- This left leg 22b in FIG. 12 then continues in the vertical tab 24b, which the insulation displacement slot 27b with the insertion bevels 26b 15, 16 as shown in FIGS.
- connection relationships in the field of screwless Terminal contact point trained 16b in the sub-housing 3b are the same as in Fig. 2 and need no further explanation.
- a clamping spring 28b is inserted into the contact spring 20b, the basic shape of which can be seen from FIG. 12 is.
- the clamping spring 28b is approximately triangular with a cut free and bent up in her lower leg Rag 95.
- the contact spring 20b With a connecting tab 96 provided (Fig. 15, 16), which can be seen in Fig. 14 Protrudes into the fuse housing 92, in which them with one plugged onto them, essentially U-shaped resilient fuse holder bracket 94 electrically is conductively connected.
- the fuse holder bracket 94 serves to accommodate one indicated at 95 Microfuse in the known way.
- a second such fuse holder bracket 94 is arranged, the one with a connecting tab 99 (Fig. 17) of the other Contact spring 20b '(FIG. 12) in a corresponding manner, as in Fig. 14 is electrically connected.
- Those in the sub-housing 2b are electrically insulated from the contact spring 20b accommodated contact spring 20b 'is essentially L-shaped (Fig. 12) and at 85b means of a folded part formed double-walled as well provided with the threaded hole 86b.
- the one in the threaded hole 86b screwed-in clamping screw 87b is shown in FIG. 12. Via the housing opening 90b from the outside (above) accessible.
- FIG. 11 For inserting a miniature fuse 95 into the two fuse retaining clips 94 is one shown in FIG. 11 at 100 box-shaped cover part that has an operating handle 101 and two in pairs lying vertically one above the other integrally formed clamping arms 102, 103.
- the microfuse is between the clamping arm pairs 102, 103 95 resiliently clamped, with a spare fuse in the Space between the upper clamp arms 102, 103 and the top wall 104 of the box-like cover part can be accommodated can.
- the lid part 100 is then from above into the Fuse housing 92 inserted until the between the Arm pairs 102, 103 held microfuse 95 between the Holding clips 94 is jammed.
- the fuse housing 92 not to be molded onto the sub-housings 2b, 3b, but as to form a separate part, e.g. by means of the side molded coupling parts 50 or 51 corresponding to FIG. 2 be coupled to a single element according to Fig. 1 or 7 can, whereby in these individual elements only precaution for accommodating the contact springs 20b and 20b ' 12 and 20a of FIG. 8 and a corresponding, second contact spring isolated therefrom would have to be such that both contact springs are above devices with which they attach to fuse holder clips 94 electrically on the bottom of the fuse housing 93 can be connected conductively.
- the invention therefore also includes a kit in which such individual elements of the same and different functions are included and which allows the user to use a small number of different individual parts Individual elements and different from these Clamping devices according to their respective needs build up.
- clamping devices assembled in this way for example in the form of a multi-pole terminal or Terminal strips can also be assigned to additional devices be responsible for the use of these clamps are advantageous and are added so that they do not Changes to the individual elements themselves required do.
- the strain relief has a flat, substantially T-shaped Base part 105, which consists of insulating material and on a hinge 106, a line clamping web 107 is held captive by means of two clamping screws 108, the threaded bushes 109 in the Cross legs of the base part 105 are associated with this can be screwed.
- clamping ribs 110 which deepens are arranged ensure in the usual way the correct position tensile fixation of the under elastic Deformation of the conductor insulation jammed between them electrical wire.
- the partial housing 2, 2a, 2b For coupling the strain relief to the individual elements 1, 7 and 11 are the partial housing 2, 2a, 2b each starting from the end face 14 or 14a, 14b cross-sectionally rectangular with parallel flanks
- Provide connecting channels 114 which extend over part of the Length of the partial housing 2, 2a, 2b extend and laterally are delimited by two parallel webs 115, which are opposite the adjacent side surface of the respective sub-housing are set back inside.
- the webs 115 are on their side facing the separating surface 5 in each case through an outward penetrating side wall opening rectangular latching opening 116 limits the exact Dimensions can be seen from Fig. 3. Otherwise open is formed on the underside by a molded web part 117 (Fig. 3) limited connection channels 115 behind the Locking opening 116 on the underside of the partial housing 2 (2a, 2b) in the area between the locking arms 8, like this also emerges from Fig. 3.
- connection channels 114 are chosen such that each connection channel 114 in the out Fig. 18 can be seen way for receiving a pair of locking fingers 112 is set up, the latching hook in the inserted Snap the condition into the locking opening 116 and so that the molded part 105 of the strain relief fix securely.
- the lateral distance between the locking finger pairs 112 on the base part 105 to the pitch of Individual elements i.e. whose partial housing 2 matched, so that with a two-pole clamping device the molding 105 with its locking fingers 112 in the connecting channels 114 neighboring individual elements can be used.
- the Strain relief is thus with that between the ribs 110 jammed cable on the middle between the two individual elements, i.e. whose connection point pairs 14 aligned.
- the webs 115 are opposite the adjacent side walls the partial housing 2 (2a, 2b) is set back by such an amount, that between two via the coupling elements 50, 51st positively coupled individual elements each again an insertion channel 114 'is limited, which after has the same cross-sectional dimensions at the bottom like the connection channel 114 of a single element.
- the grid of the connecting channels 114 'strung together Individual elements are the same as the grid of the connecting channels 114, as can be seen from FIG. 19, the base part 105 of the strain relief optionally also in two neighboring ones Connection channels 114 'inserted and in their locking openings 116 can be locked. In the three-pole shown Clamping device means that this is in the strain relief connecting cables clamped over the ribs 110 now on the connection points 14 of the middle single element is aligned.
- Individual elements can also have several strain reliefs are provided in such a way that molded parts 105, for example, also abutting with their transverse legs are attached.
- connection channels 114 in the described Way with the webs 115 on both sub-housings 2, 3rd (2a, 2b; 3a, 3b) are only provided for those the other sub-housings 3 (3a, 3b) with such connection channels are executed.
- strain relief in that even after the clamping device has been installed, for example in a lamp later can be inserted without the attachment of the Clamping device would have to be solved. Because the strain relief has a base part 105 inserted at the end, there are also short, simple routes for the leading the clamped cable into the connection points Cables.
