Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a solar connector mounting tool, which is used for mounting a solar connector. In such a solar connector, a connector housing is moved relative to an assembly and thereby pushed onto the assembly and pressed by means of this pushing. The assembly is formed here with a cable and a connector pressed with the cable and in some cases with a seal arranged on the cable.

STATE OF THE ART

It is known, for example from the Internet page www.tritec-energy.com/images/content/D_174_Rennsteig_UniversaiKit_iNST_des.pdf, a "Operating Instructions Solarkit Universal MC" (Rev. 2011-08-01 ) of the company Rennsteig Tools, in which a solar connector assembly tool for MC3 type solar connectors is illustrated and described with regard to its use. In this solar connector-Aufziehwerkzeug a conical expanding mandrel is loosely inserted into a continuous recess of a connector housing. The plug housing with the expanding mandrel disposed therein is then inserted from a first end face into a housing of the solar connector mounting tool. The expanding mandrel has a coupling head. This coupling head is coupled with a pull and reset rod which extends to and beyond a second end face of the solar connector mounting tool opposite the first end face of the housing such that the pull and reset rod projects out of the solar connector mounting tool. About a manual operation of a relative to the housing of the solar connector-Aufziehwerkzeugs pivotable hand lever, in which a magazine for an expanding mandrel is integrated, the tension and return rod can be moved out of the housing in several stages of actuation with pivoting opening and closing movements of the hand lever. In view of the coupling of the tension and return rod on the coupling head with the mandrel is pulled with this movement of the tension and return rod and the expanding mandrel in the direction of the plug housing until it comes with its Aufweitkonus to rest against the connector housing. Now, a cable with a crimped connector corresponding to the insertion path of the expanding mandrel is inserted into the housing of the solar connector mounting tool until the connector reaches a stop of the expanding mandrel. Following this, a guided against the housing Kabelklemmung is clamped on the cable and pushed to the stop in the direction of the plug housing. By repeated stepwise pivoting of the hand lever, the mandrel is then pulled with a plug and cable through the connector housing until the connector and cable have reached their destination in the connector housing. During this pulling through the mandrel and the connector with cable through the connector housing, the connector housing does not move. Finally, the cable with plug and connector housing is removed from the solar connector mounting tool. The operating instructions recommend a subsequent check of the proper fit of the plug housing on the cable and the plug.

OBJECT OF THE INVENTION

The invention has for its object to provide a solar connector mounting tool by means of which a reliable intended assembly of an assembly formed with a cable and a cable pressed connector with the cable (and in some cases with a seal arranged on the cable), is guaranteed with a connector housing.

SOLUTION

The object of the invention is achieved with the features of the independent claim. Further preferred embodiments according to the invention can be found in the dependent claims.

DESCRIPTION OF THE INVENTION

The invention relates to a solar connector assembly tool by means of which a connector housing can be pushed or pulled onto an assembly. This assembly is formed with a cable and a connector pressed with the cable. Under certain circumstances, the assembly also has a seal arranged on the cable. The solar connector mounting tool according to the invention in this case comprises embodiments in which a sliding or pulling relative movement between the plug housing and assembly takes place, so that in this case a relative movement of the plug housing and / or the module can be done.

The embodiment according to the invention is based on the finding that, for the known solar connector assembly tools, compliance with a predetermined orientation or angle of rotation of the plug in the plug housing depends on how carefully the user of the solar connector mounting tool inserts the assembly formed in the solar connector. Mounting tool inserts. Even if the mounting of the assembly group is done very carefully with the correct orientation, it may lead to undesirable changes in the orientation of the connector before the final assembly of the connector housing with the assembly, which the user may not see properly inside the solar connector assembly tool , Since the plug housing is plugged into a counter plug housing in a defined orientation predetermined by the geometry of the plug housing, it may therefore happen that the plug mounted in the plug housing with incorrect orientation does not properly cover the counter plug housing arranged in the opposite plug housing. Plug contacted or even collided with this, whereby the plugging of the plug housing in the mating connector housing may be impossible.

According to the invention it is proposed against this background that the solar connector mounting tool has a test device, via which the insertion of the module, in particular of the plug, can be checked with the correct orientation in the solar connector mounting tool. This can be done immediately with or after inserting the module. It is also possible that the test takes place immediately before moving the connector housing on the assembly for the purpose of re-testing immediately before mounting. Thus, according to the invention, the mounting reliability with respect to the orientation of the package in the plug housing can be increased.

In a further embodiment of the invention, the test device has a test position and a rest position. For example, in a rest position, the tester does not interact with the assembly. In the rest position, the insertion of the assembly in the solar connector assembly tool can be made possible or simplified. It is also possible that the rest position is taken during the movement, in particular the pushing or pushing or pulling of the plug housing relative to the assembly, whereby this assembly operation is not hindered by the testing device. On the other hand, in the test position or on the way from the rest position to the test position, the actual test is carried out as to whether the module is inserted with the correct orientation into the solar connector mounting tool.

The test device can be of any desired design and have any degrees of freedom that can include the test position and the rest position. For a particular embodiment of the invention, the test device by movement transversely to the mounting direction of the rest position in the test position (and vice versa) movable. Thus, the tester can be moved over short distances away from the module and in the direction of this.

The test device can work in any way. By way of example only, a non-limiting example may be made by means of the test device, for example, by checking that an edge of the plug is aligned with a reference edge or mark of a housing of the solar connector mounting tool. For a particular embodiment of the invention, however, a positive test is carried out: With this embodiment, the movement of the test device is blocked from the rest position to the test position, if the test device is not inserted with the correct orientation in the solar connector assembly tool, while the movement of the test device is not is blocked when the module is inserted in the solar connector mounting tool with the correct orientation. Thus, the user can tentatively operate the testing device and check whether a blockage occurs, which is an indication of whether the correct orientation is guaranteed.

It is possible that the testing device has several possibly multi-stable positions such as the test position and the rest position. In a particular embodiment of the invention, the test device is acted upon by a spring in the rest position, so that it is taken automatically. If the test device is then manually applied by the user, overcomes the user by actuating forces the spring, with which the test device can be transferred from the rest position to the test position.

In the test device, any test body can be used, which has, for example, a suitable contact surface, which can come to rest on a reference surface of the plug, if this is inserted in the correct orientation in the solar connector mounting tool, while the movement of the test specimen for other orientations is blocked. For a particular embodiment of the invention, however, the test device is formed with a test specimen having an open-edged recess. Through this open-edged recess extending in the test position of the plug. In other words, the test body can be pushed with the open-edged recess in the movement from the rest position to the test position with the open-edged recess, for example fork-shaped, over the plug when the plug is inserted in the correct orientation in the solar connector mounting tool.

DESCRIPTION OF THE FIGURES

Fig. 1 shows exemplary and highly schematic of a solar connector 1. On a cable 2, a seal 5 is arranged at a defined distance 3 from a front side 4. The seal 5 adjacent end portion of the cable 2 is stripped and crimped over a crimping tool with a plug 6. On a pre-assembled assembly 7 formed in this way, a connector housing 9 is moved, pushed or pressed by means of a solar connector assembly tool 8. In the in Fig. 1 shown fully assembled position of the solar connector 1 latches a locking lug 10 behind the plug 6. The seal 5 is compressed radially between the outer surface of the cable 2 and the stepped inner surface 99 of the plug housing 9. This is to ensure a seal of the solar connector 1. In addition, via the compression of the seal 5 between the connector housing 9 and cable 2 is a recording of acting on the cable 2 during operation forces, whereby a "strain relief" can be done.

Fig. 2 shows the solar connector mounting tool 8 in a three-dimensional view. The solar connector mounting tool 8 has a "gun-shaped" design, wherein the solid "pistol grip" forms a housing-fixed lever 11, while the "trigger" is extended according to the length of the hand lever 11 and forms a pivotable hand lever 12. The run" indicates a mounting axis 34 with a mounting direction 97 along which takes place in the solar connector assembly tool 8 moving, here pushing the plug housing 9 on the assembly 7. A housing 13 of the solar connector mounting tool 8 is formed with two half shells 14, 15, which form a dividing plane in a longitudinal center plane of the solar connector mounting tool 8.

The solar connector mounting tool 8 has a drive mechanism 16, a moving unit 17, a checking device 18, and a fixing unit 19.

The drive mechanism 16 is formed with the pivoted hand lever 12, which is rigidly connected within the housing 13 with a drive crank 20 ( Fig. 5 ). As in particular in Fig. 4 can be seen, for the illustrated embodiment, the hand lever 12 in the connected to the drive crank 20 end portion has a flattening in the region of which the hand lever 12 via a connecting pin 21 and a pivot pin 22 fixedly connected to two on both sides of the flattened plate-shaped drive crank plates 23, 24 connected , which together form the drive crank 20. The pivot pin 22 is pivotally mounted in the projecting from the drive crank plates 23, 24 end portions in the half-shells 14, 15 of the housing 13, so that the hand lever 12 with the drive crank 20 is pivotable about a predetermined by the pivot pin 22 pivot axis. The drive crank 20, here the drive crank plates 23, 24, owns / have off the pivot pin 22 an extension 25 (FIG. Fig. 5 ), to which a spring base of a tension spring 26 is articulated. The other spring base of the tension spring 26 is supported under prestress on a bolt 27 which is mounted endwise in the half shells 14, 15 of the housing 13. The spring bias of the tension spring 26 causes the hand lever 12 in Fig. 5 is applied with a torque counterclockwise, so that the hand lever 12 is acted upon by the hand lever 11 away. Hand lever 12 and drive crank 20 together form a lever, wherein hand lever 12 on the one hand and drive crank 20 are arranged on opposite sides of the pivot pin 22 formed with the pivot bearing. In Fig. 4 and 5 It can be seen that, in the end region facing away from the pivot pin 22, the drive crank 20 is held by the drive crank plates 23, 24, a pivot pin 28. On the pivot pin 28, a toothed plunger 29 is pivotally mounted between the drive crank plates 23, 24. The pivot axis of the toothed ram 29 is in this case oriented parallel to the predetermined by the pivot pin 22 pivot axis. The toothed ram 29 extends from the pivot pin 28 at the front, wherein the toothed ram 29 is acted upon by a spring element, here a via a housing-fixed pin 30 supported spiral leg spring 31, upwards. The toothed ram 29 has a toothed segment 32 in its end region facing away from the pivot pin 28. The toothed segment 32 interacts with a guide slide 33, which is displaceably guided in the direction of the mounting axis 34 with respect to the housing 13. The guide carriage 33 has on its underside a rack-like toothing 34, whose longitudinal extension in the direction of the mounting axis 34 corresponds at least to the desired assembly stroke of the solar connector assembly tool 8. The toothed segment 32 engages as a result of the loading by the spiral leg spring 31 in the toothing 35 a. The tooth contours of the toothed segment 32 and the toothing 35 are selected such that the guide carriage 33 manually in Fig. 5 can be moved to the right in the direction of the mounting axis 34, while the toothed segment 32 rides like a ratchet along the toothing 35 and repeatedly the toothed plunger 39 is pressed under application of the spiral leg spring 31 down so that the toothed segment 32 successive counter-tooth segments of the toothing 35 overcome can. On the other hand, the interaction between the toothed segment 32 and the toothing 35 blocks a manual movement of the guide carriage 33 Fig. 5 against the mounting direction 97 to the left, if not by additional, described in detail below measures the toothed ram 39 from the teeth 35 is lifted manually. An additional securing of a once reached position of the guide carriage 33 via a Zwangsgesperre 36. For this purpose, a pawl 37 via a pivot pin 38 is pivotally mounted relative to the housing 13. About a likewise supported on the housing 13 spring element, here a spiral leg spring 39, and the pawl 37 with a toothed segment 40 of the same against the teeth 35 is applied. The toothed ram 29 and the pawl 37 are in this case offset in the direction of the mounting axis 34, but arranged with a certain overlap, while these are offset transversely to the mounting axis and transversely to the longitudinal center plane. In the end region opposite the pivot pin 38, the pawl 37 has an actuating pin 31, which passes through a guide slot 42 in the half shell 15 of the housing 13. As a result of the action of the spiral leg spring 39 is without applying manual forces on the actuating pin 41, the pawl 37 in the in Fig. 5 shown upper end position, in which caused by the spiral leg spring 39, the toothed segment 40 can enter into operative connection with the toothing 35 in order to secure the once reached axial position of the guide carriage 33. If, however, the actuating pin 41 is pressed manually outside the housing 13 down, the toothed segment 40 of the pawl 37 is excluded Engagement with the toothing 35, whereby the securing effect of Zwangsgesperres 36 can be canceled. Via a driving pin 43, the toothed plunger 49 is also driven downwards by the pawl 37 when the actuating pin 41 is manually actuated downwards, so that the toothed segment 32 of the toothed plunger 29 is also disengaged from the toothing 35. Between guide carriage 33 and the housing 13 acts a spring 44 which pulls the guide carriage 33 against the mounting direction 97 to the rear, when both the toothed segment 32 and the toothed segment 40 is out of engagement with the toothing 35.

The movement unit 17, which can also be designed as a holding, drive and / or guide unit, is formed with the guide carriage 33. The guide carriage 33 has in the mounting direction in the rear end region 97 has a U-shaped cross section, the base leg of a base plate 45 and the side legs of two parallel side plates 46, 47 are formed. While the side plate 46 is formed continuously over the entire length of the guide carriage 33, the side plate 47 ends approximately centrally, so that in the front end region of the guide carriage 33 has only an L-shaped cross section. The base plate 45 is equipped with a suitable contour 48, which is adapted to the outer contour of the plug housing 9. Fig. 6 shows a side view of the guide slide 33 shown here transparent with a holding body 49 disposed therein. The holding body 49 is rotatably connected to a transversely extending to the mounting axis 34 pivot pin 50 which by aligned through holes 51, 52 of the side plates 46, 47 and parallel to the mounting axis 34 oriented guide slots 53, 54 passes through the housing 13 and in the end regions rotatably connected with wing nuts 55, 56 is connected ( Fig. 7 ). In Fig. 2 and 14 is the holding body 49 in a first operating position, in which the holding body 49 can hold a plug housing 9 with a first geometry. This holding can consist in that the plug housing 9 rests against an end face 57 of the holding body 49 and is supported. It is also possible that the end face 57 is suitably contoured to allow the holding of the plug housing 9, has a recess into which the plug housing 9 enters or the holding body 49 is "encompassed" by a sleeve-like plug housing 9. With a rotation of at least one wing nut 55, the holding body 49 about a predetermined by the pivot pin 50 pivot axis in Fig. 6 can be pivoted by 180 ° in a second operating position counterclockwise, in which the holding body 49 can hold a connector housing 9 with a second geometry deviating from the first geometry. In this second operating position, the plug housing 9 then faces the end face 57 opposite the end face 58. Again, the holding of the connector housing only in a support on the end face 58, the interaction by corresponding contouring of the end face 58 and the plug housing 9, entry of the plug housing 9 in a recess of the end face 58 or embrace the holding body 49 by the connector housing 9. For the illustrated embodiment, the pivot pin 50 is eccentrically arranged in the holding body 49 such that the distance 59 of the end face 57 of the pivot axis of the pivot pin 50 is greater than the distance 60 of the pivot axis of the pivot pin 50 from the end face 58. This has the consequence in that, depending on the operating position of the holding body, the support of a plug housing 9 takes place at different locations along the mounting axis 34, whereby different longitudinal extensions of different plug housings 9, in particular as a result of a male and a female plug housing, can be accommodated. For example, shows Fig. 17 a male connector housing 9, which has an extension 61, in the region of which the connector housing 9 is supported on the end face 58. If, on the other hand, a corresponding female plug housing is used which does not have the extension 61, the operating position of the holding body 49 is changed in such a way that this plug housing 9 is supported on the end face 57. In this case, the difference of the distances 59, 60 correspond to the length of the extension 61, by which the male connector housing 9 is longer than the female connector housing 9. It is possible that the holding body 49 with its underside in the two operating positions on the base plate 45th is supported. Under certain circumstances, an additional backup of the operating positions of the holding body 49, for example by a locking or locking device. For this purpose, transversely to the mounting axis 34 in the holding body 49 (or in a side plate 46, 47), a locking element elastically supported, which engages in the operating positions in a corresponding recess of the side plate 46, 47 (or the holding body 49).

As explained, the change in the operating position of the holding body 49 can be caused by a rotation of the wing nuts 55, 56. The pivot pin 50 has, together with the holding body 49 and the guide carriage 33 in the direction of the mounting axis 34 and by the guide slots 53, 54 predetermined (further) degree of freedom. A manual loading of the wing nuts 55, 56 in mounting direction 97 causes pushed as a unit of the guide carriage 33 with holding body 49 and the supported on the holding body 49 plug housing 9 in the mounting direction 97 to the front be, with the toothed segments 40, 32 move ratchet-like along the teeth 35.

The fixing unit 19 is arranged in the front end region of the "run" of the solar connector assembly tool 8 and serves to position and hold the pre-assembled assembly 7. The fixing unit 19 is shown in different disassembly stages in particular in the Fig. 10 to 13 and 15, 16 and 20. The fixing unit 19 is formed with a drive body 62, which is here plate-shaped, has only one degree of freedom parallel to the mounting axis 34 and is guided relative to a guide carriage 93. Via a spring element 63 of the guide carriage 93 is biased against the assembly direction 97 to the rear under bias against a stop 64 of the housing 13. If a force is exerted in the mounting direction 97 on the guide carriage 93, which force is greater than the pretensioning of the spring element 63, the guide carriage 93 can become detached from the stop 64 of the housing 13, so that a movement of the guide carriage 93 takes place in the assembly direction 97. An actuator 65, here an operating wheel 66, transverse to the mounting axis 34 by applying an actuating force 67 in the direction of in Fig. 15 shown dissolved position to be actuated while the actuator 65 due to a spring without applying the actuating force 67 in the in Fig. 16 shown fixing position returns. With the movement of the actuating member 65 between the two mentioned positions, a groove body 68 is moved. The groove body 68 has on its underside pointing to the drive body 62 a slot or a long groove 69, whose or its longitudinal axis both relative to the mounting axis 34 and with respect to the actuation direction of the actuating member 65 is inclined. In the slot or the long groove 69 engages a sliding block or pin 70, which extends from the drive body 62 upwards. With the elongated hole 69 and the pin 70, a drive connection stage 71 is formed, by means of which, in view of the inclined orientation of the slot 69, a movement of the groove body 68, caused by the actuation of the actuator 65, is converted transversely to the mounting axis 34 in a movement of the drive body 62 coaxial to the mounting axis 34. The drive body 62 has two V-shaped elongated holes 72, 73, which extend symmetrically on both sides of the mounting axis 34. The longitudinal axis of the elongated holes 72, 73 is both inclined relative to the mounting axis 34 and to the actuating direction of the actuator. Transverse to the mounting axis 34 are compared to the guide carriage two jaws 74, 75 out, which in particular in Fig. 11 can be seen. The jaws 74, 75 each have V-shaped clamping surfaces 76, 77 which together in cross-section parallelogram are arranged and a clamped in the jaws 74, 75 cable 2 clamp over the circumference, wherein the size of the parallelogram is dependent on the distance of the jaws 74, 75 from each other and thus of the diameter of the cable 2. The jaws 74, 75 are in Direction of the mounting axis 34 offset from each other, so that they are guided past each other laterally. The jaws 74, 75 each have on the bottom downwardly extending sliding blocks or pins 78, 79, with which they engage in the slots 72, 73 of the drive body 62. In this way, a further drive connection stage 80 is formed, which is a movement of the drive body 62 in the direction of the mounting axis 34, which is caused by an actuation of the actuator 65 using the drive connection stage 71 converts into a movement of the jaws 74, 75 transversely to the mounting axis 34, namely a movement of the jaws 74, 75 toward or away from each other. Like also in Fig. 15 can be seen, the jaws 74, 75 acted upon by springs 81, 82 which are supported on the housing 13 to each other. Finally, by actuation of the actuating member 65, opening of the clamping jaws 74, 75 can take place such that a cable 2 is inserted into the fixing unit 19 from above. The elimination of the actuating force 67 causes the operating position of the fixing unit 19 of Fig. 15 in Fig. 16 changed, which as a result of the springs 81, 82 and possibly another spring 83 which acts on the groove body 68 or the actuator 65, the jaws 74, 75 are closed until the clamping surfaces 76, 77 to the outer surface of the cable 2 to the plant come and pinch this and fix it. Here, the axial position of the assembly formed with the cable 2 7 is selected such that the seal 5 is in a predetermined axial position, which in particular rests against an end face of the guide carriage 93. This inserted into the solar connector assembly tool 8 state of the assembly 7 is, for example, in Fig. 17 shown. In this position, the plug housing 9 on the one hand and the assembly 7 on the other hand are arranged coaxially with each other.

The checking device 18 is arranged between the moving unit 17 and the fixing unit 19. For the illustrated embodiment, the test device 18 is formed with a test specimen 84. The test body 84 has an actuating button 85 and a hereby rigidly connected actuating plunger 86, which extends through a leading bore 87 of the half-shell 14 of the housing 13 therethrough. By means of a spring 88, which extends for the illustrated embodiment, outside of the housing 13 around the actuating plunger 86 around and caught and biased between the housing 13 and the operating knob is, the test piece 84 is applied without manual application of the actuating knob 85 to the outside. Manually, the test piece 84 can be pressed transversely to the mounting axis 34 inwardly into the housing 13. By means of corresponding (not shown) guide elements ensures that the test body 84 is not rotated about its actuating axis. Without manual operation of the specimen 84, the test device 18 is in the in Fig. 8 and Fig. 17 shown rest position. In the end region located in the housing 13, the actuating tappet 86 is formed in a rough approximation in the form of a horizontal U, so that it forms an open-edged recess 89, which is bounded by webs 90, 91. The plug 6 is formed out of round, namely flattened, in particular as a result of the crimping process in the axial region where it interacts with the test body 84. If the plug 6 is in the correct orientation, ie if it is inserted with the correct angle of rotation around the mounting axis 34 into the solar connector mounting tool 8, the plug 6 can enter the open-edged recess 89 as a result of its flattening, thus achieving a test position. If, however, the plug 6 is rotated relative to this correct orientation about the mounting axis 34, the plug 6 can not enter the open-edged recess 89, but rather collides with the recess 89 limiting webs 90, 91 of the actuating plunger 86. For the illustrated embodiment, the Webs 90, 91 formed multifunctional by not only limit the recess 89, but also form at the end portions 92 heels over which the test body 84 can be locked in the bore 87 and prevents the test specimen 84 due to the bias of the spring 88 is completely pushed out of the housing 13. It is also possible that in the event that the fixing unit 19 is released manually and the test device 18 is actuated, the webs 90, 91 of the test body 84 rotate the assembly 7 in the correct orientation.

In principle, it is possible that the described fixing unit 19 is fixed in the direction of the mounting axis 34. For the illustrated embodiment, however, the fixing unit is formed with a guide carriage 93, on which in the direction of the mounting axis 34 slidably the drive body 62 is mounted and the other explained components of the fixing unit are supported. The guide carriage 93 is pressed counter to the mounting direction 97 of the movement unit 17 by the prestressed spring element 63 against the stop 64. If a force is applied to the guide carriage 93 in the mounting direction 97, which is greater than the biasing force of the spring element 63, the guide carriage 93 can detach from the stop 64, so that the guide carriage 93 (and herewith the other components the fixing unit 19) in the mounting direction 97 can move. In order to ensure this degree of freedom of the guide carriage 93 with the associated components of the fixing unit 19, a coupling rod 94 passes between the actuator 65 and groove member 68 through a slot 95 of the half shell 15 of the housing 13, wherein the length of the elongated hole 95 at least the permissible movement of the guide carriage 93 corresponds.

1. a) Zunächst wird das Betätigungsorgan 65 mit einer Betätigungskraft 67 manuell betätigt, um die Klemmbacken 74, 75 zu öffnen. In diesem geöffneten Zustand der Klemmbacken 74, 75 wird von oben in das Solarverbinder-Montagewerkzeug 8 die vormontierte Baugruppe 7 eingelegt. Hierbei erfolgt die axiale Ausrichtung der Baugruppe 7 derart, dass die Dichtung 5 mit der dem Stecker 6 abgewandten Stirnseite an dem Führungsschlitten 93 anliegt. Durch Beseitigung der auf das Betätigungsorgan 65 wirkenden Betätigungskraft 67 wird ein Einklemmen und fixieren des Kabels durch die Klemmbacken 74, 75 zwischen den Klemmflächen 76, 77 herbeigeführt.
2. b) Je nachdem, welcher Typ eines Steckergehäuses 9 mit der Baugruppe 7 montiert werden soll, wird durch Verdrehen einer Flügelmutter 55, 56 der Haltekörper 49 in die richtige Betriebsstellung gebracht. Dann wird das Steckergehäuse 9 des der Betriebsstellung zugeordneten Typs von oben in das Solarverbinder-Montagewerkzeug 8 eingelegt, wobei die Stirnseite 98 des Steckergehäuses 9 zur Anlage an die wirksame Stirnseite 57, 58 des Haltekörpers 49 kommt und das Steckergehäuse 9 auf der Grundplatte 45 und der Konturierung 48 aufliegt.
3. c) Jetzt oder unter Umständen auch vor der Durchführung des Verfahrensschritts b) wird durch Betätigung der Prüfeinrichtung 18 überprüft, ob für die eingelegte Baugruppe 7 der Stecker 6 richtig orientiert ist, also die randoffene Ausnehmung 89 über den Stecker 6 geschoben werden kann. Ist dies nicht der Fall, muss die Baugruppe 7 gemäß a) nochmals neu in das Solarverbinder-Montagewerkzeug 8 eingelegt werden.
4. d) Zu diesem Zeitpunkt hat eine Stirnseite 100 des Steckergehäuses 9 von der Dichtung 5 noch einen Abstand, welcher einen Leerhub 101 erfordert, der ausgeführt werden muss, bevor die eigentliche Montage erfolgt. Müsste dieser Leerhub 101 bereits durch Betätigung des Antriebsmechanismus 16 mit der sukzessiven wiederholten Verschwenkung des Handhebels 12 überwunden werden, wären hierzu mehrere Betätigungsstufen des Handhebels 12 erforderlich, was einen unnötigen Aufwand darstellen würde. Um diesen Aufwand zu vermeiden, kann durch axiale Betätigung der Flügelmuttern 55, 56 entlang der Führungsschlitze 53, 54 in Montagerichtung 97 eine Verschiebung des Führungsschlittens 33 mit dem Haltekörper 46 und darauf gehaltenen Steckergehäuse 9 erfolgen, bis die Innenfläche 99 des Steckergehäuses 9 mit der Mantelfläche der Dichtung 5 in Wirkverbindung tritt. Zu diesem Zeitpunkt ist bereits der Stecker 6 mit dem der Dichtung 5 vorgelagerten Endbereich des Kabels 2 in das Innere des Steckergehäuses 9 eingetreten. Spürt der Benutzer, dass sich zu diesem Zeitpunkt ein erhöhter Widerstand gegen die Bewegung ergibt, erkennt der Benutzer, dass der Leerhub beendet ist.
5. e) Nun beginnt der eigentliche Montage- oder Presshub, für welchen der Benutzer den Handhebel 12 in Richtung des festen Handhebels 11 verschwenkt, womit der Zahnstößel 29 um einen Teilmontagehub nach vorne bewegt wird, womit auch eine Bewegung der Verzahnung 35 und damit auch des Führungsschlittens 33 mit Haltekörper 49 und Steckergehäuse 9 einhergeht. Nach diesem Teilmontagehub und Schließung der Handhebel 11 , 12 schwenkt die Feder 26 nach Beseitigung der Handkraft den Handhebel 12 wieder weg von dem festen Handhebel 11, was zur Folge hat, dass der Zahnstößel 29 zurückbewegt wird, womit das Zahnsegment 32 ratschenartig entlang der Verzahnung 35 bewegt wird. Die Position des Führungsschlittens 33 wird hierbei über das Zwangsgesperre 36 gesichert, so dass sich der Führungsschlitten 33 trotz der Beaufschlagung durch die Feder 44 nicht zurückbewegen kann.
   Nun kann der Benutzer durch erneutes und wiederholtes Verschwenken des Handhebels 12 in Richtung des Handhebels 11 weitere Teilmontagehübe erzeugen, womit letztendlich das Steckergehäuse 9 immer weiter auf die Baugruppe 7 aufgeschoben wird. Während des Montagehubs ist insbesondere die Dichtung 5 und/oder das Steckergehäuse 9 stirnseitig an der Fixiereinheit 19 abgestützt. Diese Abstützung nimmt die von der Rastnase 10 sowie dem Reibkontakt zwischen Dchtung 5 und Steckergehäuse 9 hervorgerufen Montagekraft auf.
6. f) Während des Aufschiebens des Steckergehäuses 9 auf die Baugruppe 7 ist die ausgeübte Montagekraft zunächst kleiner als die Vorspannung, mittels welcher das Federelement 63 den Führungsschlitten 93 gegen den Anschlag 64 presst. Hierbei hängt die Montagekraft maßgeblich von der Reibkraft zwischen Dichtung 5 und der Innenfläche 99 des Steckergehäuses 9 sowie der Wechselwirkung zwischen der Rastnase 10 und der Baugruppe 7 ab. Befindet sich hingegen das Steckergehäuse 9 in der fertig montierten Stellung gemäß Fig. 1, führt eine weitere Erhöhung der Montagekraft dazu, dass sich die eine Stirnseite der Dichtung 5 an einem Absatz 96 des Steckergehäuses 9 zusätzlich abstützt, womit es zu einem weiteren Anstieg der Montagekraft kommt. Überschreitet diese Montagekraft die Vorspannung, mittels welcher das Federelement 63 den Führungsschlitten 93 gegen den Anschlag 64 presst, beginnt der Führungsschlitten 93 sich zu bewegen, womit dem Benutzer sichtbar gemacht wird, dass die Montage und das Aufschieben beendet sind und eine definierte Montagekraft überschritten ist. Ein Vergleich der Fig. 18 und 19 zeigt die Bewegung des Führungsschlittens 93 mit Überschreiten der Vorspannkraft, vgl. den sich verringernden Spalt 103.
7. g) Nun kann der Betätigungsbolzen 41 in dem Führungsschlitz 42 manuell nach unten gedrückt werden, womit die Zahnsegmente 32, 40 außer Eingriff mit der Verzahnung 35 kommen und der Führungsschlitten 33 mit Haltekörper 49 über die Feder 44 zurückgezogen werden, während das Steckergehäuse 9 in seiner montierten Position auf der Baugruppe 7 verbleibt.
8. h) Anschließend wird die Fixiereinheit 19 in ihre gelöste Stellung überführt, so dass die Klemmkräfte zwischen den Klemmbacken 74, 75 und dem Kabel 2 beseitigt werden. Wird nun an dem Kabel 2 in Montagerichtung 97 mit einer Prüfkraft gezogen, stützt sich eine Stirnseite der Dichtung 5 oder die Stirnseite 100 des Steckergehäuses 9 an dem Führungsschlitten 93 bzw. anderen Bauelementen der Fixiereinheit 19 ab. Überschreitet die Prüfkraft die Vorspannung, mit welcher das Federelement 63 den Führungsschlitten 93 gegen den Anschlag 64 vorspannt, kommt es zu einer für den Benutzer spürbaren und/oder sichtbaren Bewegung des Führungsschlittens 93. Somit kann eine Prüfung des fertig montierten Solarverbinders 1 mit einer durch die Vorspannung des Federelements 63 vorgegebenen definierten Prüfkraft noch in dem Solarverbinder-Montagewerkzeug 8 erfolgen.
9. i) Für geöffnete Fixiereinheit 19 kann nun der Solarverbinder 1 aus dem Solarverbinder-Montagewerkzeug 8 entnommen werden.

The function of the solar connector mounting tool 8 is as follows:

1. a) First, the actuator 65 is manually operated with an actuating force 67 to open the jaws 74, 75. In this open state of the jaws 74, 75, the preassembled module 7 is inserted from above into the solar connector assembly tool 8. In this case, the axial alignment of the assembly 7 takes place in such a way that the seal 5 bears against the guide carriage 93 with the end face facing away from the plug 6. By eliminating the operating force 67 acting on the actuating member 65, pinching and fixing of the cable by the clamping jaws 74, 75 between the clamping surfaces 76, 77 is brought about.
2. b) Depending on which type of plug housing 9 is to be mounted with the assembly 7, the holding body 49 is brought into the correct operating position by turning a wing nut 55, 56. Then, the plug housing 9 of the operating position associated type is inserted from above into the solar connector mounting tool 8, wherein the end face 98 of the plug housing 9 to bear against the effective end face 57, 58 of the holding body 49 and the connector housing 9 on the base plate 45 and the Contour 48 rests.
3. c) Now or under certain circumstances before the implementation of the method step b) is checked by pressing the test device 18, if the plug 6 is correctly oriented for the inserted module 7, so the open-edged recess 89 can be pushed over the plug 6. If this is not the case, the assembly 7 according to a) must be re-inserted into the solar connector assembly tool 8.
4. d) At this time, an end face 100 of the plug housing 9 of the seal 5 still has a distance which requires a Leerhub 101, which must be performed before the actual assembly takes place. Would this Leerhub 101 already by Operation of the drive mechanism 16 are overcome with the successive repeated pivoting of the hand lever 12, this would require a plurality of actuation levels of the hand lever 12, which would be an unnecessary expense. To avoid this expense, by axial actuation of the wing nuts 55, 56 along the guide slots 53, 54 in assembly direction 97, a displacement of the guide carriage 33 with the holding body 46 and held thereon connector housing 9, until the inner surface 99 of the plug housing 9 with the lateral surface the seal 5 comes into operative connection. At this time, the plug 6 has already entered the inside of the plug housing 9 with the end region of the cable 2 upstream of the seal 5. If the user senses that there is increased resistance to the movement at this time, the user recognizes that the idle stroke has ended.
5. e) Now begins the actual assembly or pressing stroke, for which the user pivots the hand lever 12 in the direction of the fixed hand lever 11, whereby the toothed ram 29 is moved to a Teilmontagehub forward, bringing a movement of the teeth 35 and thus also the guide carriage 33 with holding body 49 and connector housing 9 is accompanied. After this Teilmontagehub and closing the hand lever 11, 12 pivots the spring 26 after eliminating the manual force the hand lever 12 away from the fixed hand lever 11, with the result that the toothed plunger 29 is moved back, bringing the toothed segment 32 ratchet-like along the teeth 35th is moved. The position of the guide carriage 33 is secured in this case via the Zwangsgesperre 36, so that the guide carriage 33, despite the action of the spring 44 can not move back.
   Now, the user can generate by further and repeated pivoting of the hand lever 12 in the direction of the hand lever 11 more Teilmontagehübe, which ultimately the connector housing 9 is pushed further and further onto the assembly 7. During the assembly stroke, in particular the seal 5 and / or the plug housing 9 is supported on the front side of the fixing unit 19. This support takes on the locking lug 10 and the frictional contact between Dchtung 5 and connector housing 9 caused assembly force.
6. f) During the sliding of the plug housing 9 on the assembly 7, the applied assembly force is initially smaller than the bias voltage by means of which the spring element 63 presses the guide carriage 93 against the stop 64. Here, the mounting force depends largely on the frictional force between the seal 5 and the inner surface 99 of the plug housing 9 and the interaction between the locking lug 10 and the assembly 7. If, however, the plug housing 9 is in the fully assembled position according to Fig. 1 , A further increase in the mounting force causes the one end face of the seal 5 is additionally supported on a shoulder 96 of the plug housing 9, resulting in a further increase in the assembly force. Exceeds this assembly force the bias, by means of which the spring element 63 presses the guide carriage 93 against the stop 64, the guide carriage 93 begins to move, making the user is visible that the assembly and the postponement are completed and a defined assembly force is exceeded. A comparison of Fig. 18 and 19 shows the movement of the guide carriage 93 with exceeding the biasing force, see. the decreasing gap 103.
7. g) Now, the actuating pin 41 can be manually pressed down in the guide slot 42, whereby the toothed segments 32, 40 are disengaged from the teeth 35 and the guide carriage 33 are retracted with holding body 49 via the spring 44, while the connector housing 9 in his mounted position on the assembly 7 remains.
8. h) Subsequently, the fixing unit 19 is transferred to its released position, so that the clamping forces between the jaws 74, 75 and the cable 2 are eliminated. If a test force is now drawn on the cable 2 in the mounting direction 97, an end face of the seal 5 or the end face 100 of the plug housing 9 is supported on the guide carriage 93 or other components of the fixing unit 19. Exceeds the test load, the bias with which the spring element 63 biases the guide carriage 93 against the stop 64, there is a noticeable to the user and / or visible movement of the guide carriage 93. Thus, a test of the assembled solar connector 1 with a through the Preload the spring element 63 predetermined defined test force still done in the solar connector assembly tool 8.
9. i) For open fixing unit 19, the solar connector 1 can now be removed from the solar connector assembly tool 8.

As in the illustrated embodiments, the mounting movement may consist in that the plug housing 9 held by the movement unit 17 is pushed onto the assembly 7 held in the fixing unit 19. It is within the scope of the invention but quite possible that a fixing unit holds the connector housing 9, while a moving unit einschiebt the assembly held thereon 7 in the connector housing 9. Accordingly possible is the use of a drive mechanism by means of which a mounting or retraction takes place. For example, for a pulling movement instead of a pressure-loaded actuating tappet 86, an actuating tension element with associated drive mechanism can be used. Preferably, however, no pulling takes place through the plug housing 9, as is the case for the initially described prior art.

The wing nuts 55, 56 represent an embodiment for the formation of an actuating member 102, by means of which both the idle stroke of the guide carriage 33 can be generated as well as the rotation of the holding body 49th

It is entirely possible that a spring element is formed with a plurality of partial spring elements. For example, the biasing force for the guide carriage 93 of the fixing unit 19 for the illustrated embodiments is generated with a plurality of parallel-acting part spring elements.
