SHEET 11 0F 12 1 HARNESS MANUFACTURING APPARATUS INCORPORATING HARNESS TESTING MEANS BACKGROUND OF THE INVENTION This invention relates to an apparatus of the general type disclosed in application Ser. No. 347,965, now US. Pat. No. 3,845,535, for connecting wires to the terminals in an electrical connector. The instant invention is also related to applications Ser. No. 347.956 and 347,957 as will be more fully explained below.
Application Ser. No. 347,965, now US. Pat. No. 3,845,535, discloses and claims an apparatus for trimming the ends of wires and inserting the trimmed ends into the electrical contact terminals in a multi-contact electrical connector. One distinguishing feature of some embodiments of the apparatus disclosed in application Ser. No. 347,965, now US. Pat. No. 3,845,535, is that the portion of the apparatus which holds the connector is separate from the portion which inserts the wires into the terminals in the connector, the later part of the apparatus hving means to permit its being mounted on the former. This feature of my prior apparatus particularly adapts it for having in a harness making method and apparatus is disclosed in application Ser. No. 347,957 which teaches that a completed harness can be manufactured by lacing wires over a harness board in accordance with the wiring plan of the harness in a manner such that portions of the wires extend adjacent to connectors contained in the apparatus of application Ser. No. 347,965.When the wires are inserted by the apparatus into the terminals in the connector the harness is substantially completed and can be removed from the harness board and, after testing,
put to use.
The instant invention is directed to an improved apparatus having a means, which may be in the form of a printed circuit board, for holding the connector to which wires are to be connected. This feature facilitates the use of the prior apparatus and permits it to accommodate connectors of different sizes by merely changing the printed circuit board thereby increasing its usefulness. In accordance with a further aspect of the instant invention, the printed circuit board upon which the connector is mounted has conductors thereon that engage the contact terminals in the connector being wired. These printed circuit board conductors are, in turn, connected to wires which extend to, and form a part of, an electrical testing means so that the connector can be electrically tested and immediately after the wires have been connected thereto. This capability of the instant invention in turn permits the testing, at the time of manufacture, of a completed electrical harness as will be described below.
It is accordingly an object of the invention to provide an improved apparatus for inserting conductors into terminals in a multi-contact electrical connector. A further object is to provide a conductor inserting apparatus having improved means for holding the electrical connector to which the conductors are to be connected. A still further object is to provide a conductor inserting apparatus having means for electrically testing the connector after the conductors have been inserted into the terminals in the connector. A still further object is to provide a harness making method and apparatus having means for testing the entire harness immediately after the manufacture thereof and while the harness is mounted on a harness board.

By way of background information for the description of the instant invention, FIGS. l4I7 show features of a connector 2 which is adapted to be used in the disclosed embodiment of the invention and an electrical harness I which can be manufactured and tested in accordance with the principles of the invention. The harness I comprises a plurality of electrical connectors 2 each of which contains electrical contact terminals to which conductors 6 are connected. ,The conductors extend between and among the connectors in accordance with a predetermined wiring plan so that when the harness connectors 2 are attached to complementary connectors in an electrical apparatus, the motors, switches, control devices, etc. of the apparatus will be interconnected. The harness shown in FIG. 17 has suitable wrapping material 8 wound over the conductors as is common practice in the harness making art.
Each connector 2 (FIGS. 14-16) comprises an insulating housing I having a mating face 12 and a rearward face 14. The housing has an upper surface 18 (as viewed in the drawing) and a lower surface 20 and end surfaces 22. A plurality of contact receiving cavities extend through the housing and each cavity contains an electrical contact terminal 4.
Each terminal 4 has an elongated web 24 from the forward end of which reversely bent contact arms 26 extend for engagement with conductors on a printed circuit board. At its rearward end, each terminal has sidewalls 28 which are bent inwardly towards each other to define an open seam 30 which serves as a wire receiving slot. Advantageously, the sidewalls are partially transversely sheared on each side of the seam 30, these shear lines extending to punched holes 34 to prevent perpetration of cracks at the ends of the shear lines. As shown in FIG. 16, after a wire has been connected to the terminal, it will be received between the edges of the slot 30 and the edges penetrate the insulation of the wire and establish contact with the conducting core. The wire 6 extends laterally from the connector through an opening in the upper surface 18 which communicates with cavity in which the terminal is contained. A back cover 35 is advantageously fitted over each connector and serves as a strain relief for the wires as described in detail in the above-identified application Ser. No. 347,956.
A preferred form of inserting apparatus in accordance with the invention (FIGS. 1 and 2) comprises a fixed base section 38, which is mounted on a harness board 42, and an actuator or insertor which can be affixed to the base section 38 when the operation of inserting the wires into the terminals 4 in the connector is being carried out. Before proceeding with a detailed description of the structural details of this apparatus, it should be explained that when a harness is manufac tured, a plurality of base sections 36 are mounted on a harness board 42 (FIG. 12). Connectors 2 are mounted in each base section 38 and wires are laced over the board and between connectors. After the wire lacing operation has been completed, the actuator 40 is assembled to each of the base sections in turn and the wires are trimmed and inserted into the terminals in the connectors.
The fixed base section 38 comprises a frame 44 hav' ing a central body 46 (FIG. 9) on which there is provided an upstanding transversely extending integral rib 48 of rectangular cross-section. Feet 50 extend rearwardly as viewed in FIGS. 1 and 9 from the central body and are secured to the upper surface 174 of the harness board by suitable fasteners 52. The central and forward portions of the base section overhand, and extend into, an opening 178 in the harness board for reasons which will be explained below.
A rear wire jig or comb 54 is mounted on transverse rib 48 and comprises an elongated bar 56 which is disposed against the rightwardly facing side of rib 48 as shown best in FIG. 9. A plurality of spaced apart barriers 58 are provided on the upper surface of the bar 56 and extend leftwardly as viewed in FIG. 4 over and beyond the upper surface of the rib 48 of the frame.
The forwardly extending portions of these barriers (which are on the left in FIG. 4) are relatively more 5 thick than the end portions 62 as shown in FIG. 5 so that the space between the forward portions of the barriers is somewhat more narrow than the space between adjacent barriers at the rearward ends thereof. Advantageously, the spacing between adjacent barriers 58 is such that when two wires are located between two adjacent barriers, one wire will be above the other so that the two wires will be guided into the associated contact terminal as is also described below. It will be noted that the barriers are notched as shown at 60 adjacent to rearward ends 62 thereof. This notch facilitates removal of scrap wire from the comb or jig after a wire inserting operation has been carried out.
The wires are trimmed concomitantly with insertion into the terminals by means of a fixed shear bar 66 which has a generally rectangular cross-section and which has upwardly extending cars 68 at its ends, these ears being disposed against the end barriers 58 of the wire jig 54. Fixed shear 66 is secured against the leftwardly facing side, as viewed in FIG. 4, of the rib 48 and the leftwardly facing surface of the shear member is undercut as shown in 70 to define a fixed shearing edge 72 which extends parallel to, and is immediately beneath, the ends of the barriers 58. This fixed shear member cooperates with a movable shearing means mounted on the insertion tooling to cut the wires as will be later described. It is preferred practice to locate the fixed shear such that the wire enters the upper portion of the terminal before cutting of the wire is completed to ensure accurate placement of the wire.
A spacer block 74 having a rectangular cross-section is mounted against the leftwardly facing surface 49 of rib 48 immediately beneath the fixed shear 66. As will be apparent from FIG. 4, when the parts are in the positions that occupy during a wire inserting operation, the surface 18 of the housing of the connector is located against this spacer block 74. Since the connector must be precisely located with reference to the wire insertion tooling, the location of spacer 74 is important or even critical for best results. The shear bar 66 must also be precisely located so that the wires will be cut at the desired locations. Advantageously, the spacer 74 and the shear bar 66 are both secured to the rib 48 by means of set screws which permit these members to be moved leftwardly under very precisely controlled conditions from the positions shown in FIG. 4.
The frame 44 has a pair of depending arms 76 on its lefhand end which extend into the opening 178 in the harness board and the lower ends 78 of these arms extend rightwardly as viewed in FIG. 4 so that they are substantially beneath the insertion tooling. A carrier frame 80 is pivoted on these arms in a manner described below and comprises a transversely extending bar 82 having integral latch housing blocks 84 on its ends. A pair of depending arms 86 extend downwardly from the bar 82 and are locating inwardly from the latch housing blocks 84, the lower ends of the arms 88 being outwardly offset and extending rightwardly as viewed in FIG. 4. The lower end portions 88 of the arms 86 are provided with integral bosses 89 which are disposed against the rightwardly portions 78 of the depending arms 76 of the static section of the frame. The carrier frame 80 is pivotally connected to the end portion 78 of the static portion of the frame by pivot pins 90 as shown so that the carrier frame can be swung along a counterclockwise arc from the position shown in FIG. 4.
The inwardly or opposed surfaces 92 of the bosses 89 are counterbored at 94 and slots 96 extend from these counterbores radially to the ends of the arms. These counter bores receive laterally extending ears 100 on the side edges of a printed circuit board 98 as shown in FIG. 7. The printed circuit board thus is located be tween the depending arms 86 of the carrier frame 80 and lies in a plane which is between the transverse bar 82 of the carrier frame and the central body portion of the fixed frame 44. The widths of the ears 100 are slightly less than the diameter of the counterbores so that the printed circuit can be swung about an axis extending between the centers of the counterbores. The slots 96 are provided to permit removal of the printed circuit board as will be described at a more appropriate time. It will also be noted that the printed circuit board has parallel conductors 102 on its surface and these conductors are used during testing as is also described below. The connector 2, to which wires are to be connected is simply mounted on the upper end of the printed circuit board 102 so that the board serves as a mounting means for the connector during operation.
A front wire jig or comb 104 is mounted on the transverse bar 82 of the carrier frame 80. This front wire jig comprises a generally channel-shaped member having a central web 106, and depending flanges 108, 110. On its upper surface, there are provided a plurality of spaced apart barriers 112 which have the appearance of trunkcated triangles but which may be rectangular if desired. These barriers are spaced apart by distances corresponding to the spacing between the barriers on the rear wire jig 54 so that wires placed between aligned barriers in the two-wire jigs will be located above the terminals contained in the connector in FIG. 4. The wire jig 104 is secured to the rib or bar 82 by suitable fasteners with the web against the upper surface of the bar and depending flanges 108, 110 straddling the bar 82.
Latching means are provided for latching the carrier frame 80 in its closed position as shown in FIGS. 2 and 4, this latching means comprising latch levers 114 which are pivotally mounted in slots 116 on the downwardly facing sides of the latch housings 84 on the ends of the transverse bar 82 of the carrier frame 80. The forward ends of the levers are hooked as shown at 119 and are adapted to engage latch dogs 120 mounted in recesses on the upwardly facing surfaces of the frame member 44. The levers 114 are resiliently biased in a clockwise direction as viewed in FIGS. 3 and 4 by springs 122 which are contained in recesses in the housing blocks 84 and which bear against the latch arms adjacent to the hooked ends thereof.
As shown in FIGS. 3 and 4, an additional latch dog 124 is provided which extends horizontally from one of the depending arms 76 of the fixed frame 44. This horizontally extending latch dog comprises a stamped plate-like member and prevents the carrier frame 80 from swinging in a counterclockwise direction beyond the position shown in FIG. 3. The latch arm 114 which engages the fixed latch dog 124 can be disengaged from the dog when it is desired to swing the carrier frame through a further counterclockwise arc to change the printed circuit board 78.
It should be explained at this point that the fixed or lower tooling is loaded with a connector 2 by opening the carrier frame to the position of FIG. 3. The printed circuit board 98 is swung through a slight counterclockwise are so that it is directed obliquely upwardly between the carrier frame 80 and the central portion of the fixed frame 54. A connector 2 is then mounted on the upper end of the printed circuit board 102 and the carrier frame is then swung through a clockwise arc to its closed position and the latch arms 114 engage the latch dogs 120. The printed circuit board is precisely centered when the parts are in their closed positions by positioning blocks 126 which are mounted against the opposed surfaces of the frame 44 adjacent to the central portion thereof. The edges of the printed circuit board move over these positioning blocks 126 and the board is thereby precisely centered and the connector will also be precisely centered with its contact terminals in alignment with the spaces between barriers in the wire jigs and in alignment with the insertion punches 160 in the insertion tooling described below.
The actuator or movable tooling member 40 is mounted on the frame 44 by means of channels 128 which have inwardly directed cylindrical housings 134 and laterally extending arms 133 on their sidewalls. These mounting channels are secured in notches 130 in the oppositely facing sides of the central portion of the frame by fasteners 132 which extend through the mounting arms 133 in the channels and into the frame. The mounting means for the upper tooling comprises, in each channel, a pin 136 is contained in the housing 134 and which extends through an opening in the web of the channel, pin 136 has a reduced diameter end portion which extends through a central opening in the end wall of the cylindrical housing 134 on the channel. A spring 140 is interposed between the end wall of housing 134 and a shoulder on the pin. This spring normally biases the pins outwardly through the web but these pins can be moved inwardly against the compression of the springs 140 by suitable handles 142 provided on the ends of the pins 136.
The upper portion 40 of the tooling is mounted on the lower tooling assembly 38 by merely locating the upper tooling above the lower tooling as shown in FIG. 1 and moving the lowering the upper tooling in the position of FIG. 2 so that the legs 144 move into the channels 128 and cam pins 136 inwardly. The pins then move through the webs of the channels and into openings 146 on the lower ends of the mounting arms 144. The upper tooling is removed by retracing the pins by means of the handles 142.
The upper tooling comprises a housing 146 having a cover plate 148 in which a slide member 150 is contained and guided. Slide 150 has an insertion tool holder 152 secured to and extending across, its lower end and a channel 154 is provided in this tool holder in which the inserter 158 is mounted. The rightwardly facing flange as viewed in FIG. 4 on the lower end of tool holder 152 provides a shearing edge 156 which, during descent of the slide, moves past the fixed shearing edge 72 to shear the wires which have previously been positioned in the wire jigs 54. The inserter 158 has a series of pairs of depending inserting punches 160 and 162 which are so dimensioned that they will push the trimmed wire into the terminal with which they are associated as shown in FIG. 4. The left hand flange 157 of the tool holder 152 cooperates in this wire inserting step so that after the slide 150 has reached the lower most limit of its travel, the wire will be located in the slot of the associated terminal.
The slide 150 is resiliently biased upwardly by suitable spring means (not specifically shown) and is moved downwardly on by a cam 166 which is mounted on a pin 164 which is supported in extending bearing portions 162 of the housing 146. A handle 168 is supported on the pin 164 and is secured to the cam 166 by a pin 167 so that if the handle 168 is swung through a counterclockwise arc from the position of FIG. 4, the contoured surface of the cam will engage a cam follower 170. This cam follower is mounted in the upper end of the slide 150 so that the slide and the inserter, which is carried thereon, will be moved to its lowered position. it is desirable to provide auxiliary means for lifting the slide from its lowered position and to this end, I provide crescent shaped lifts 172 on each side of the cam 166. These lifts are so contoured that they will engage pins on the cam 166 and lift the slide when the handle 168 is returned to the position shown in FIG. 4.
FIG. 9 shows the upper surface 174 of a harness board on which four lower tooling assembles 38 have been mounted adjacent to openings 178 in the harness board. A harness board so arranged might be used to produce extremely simple harness as shown in FIG. 14. To produce such harness, each of the lower tooling assemblies are loaded with a connector 2 and the tooling assemblies are closed as described above, that is the carrier 80 is swung to its closed position (FIG. 4) and latched. Wire or wires are then laced over the harness board between suitable guide and retaining pegs 175 between and among the several tooling assemblies in accordance with the desired wiring plan. The wire is not cut at the fixed tooling assemblies 38 but is laced in and out" through each assembly. In other words, the wire enters an assembly adjacent to the board openg 178, is laced between aligned barriers 112, 58 in the wire jigs 104, 54 and then is reversed and laid between another pair of aligned barriers in the same assembly. Thereafter, it is laid on the board along a path extending to another pre-determined lower tooling as sembly 38 and the process is repeated. Ocassionally, it may be necessary to cut a wire at a tooling assembly and start anew as explained in the above identified application Ser. No. 347,957. The wire for the lacing operation may be drawn from an endless source such as a reel.
After the wires have been laced over the board. the upper tooling assembly 40 is assembled to each of the four lower tooling assemblies 38 in turn and the handle 168 is swung to cut the wires and insert the cut ends into the terminals in the connectors 2. The cutting operation will result in the production of loops of scrap wire adjacent to the rearward wire jigs 54 and these can be removed by passing a thin awl-like tool through the notches between the barriers 62, 58. After the upper tooling assembly has been assembled to all of the lower tooling assemblies and the wires have been cut and inserted into the terminals in the connectors 2, the barness will have been completed and testing of the barness can be carried out as described immediately below.
Referring now to FIG. 10, the underside 176 of the wiring board has a testing harness 182 supported or suspended thereon comprising wires 186 which extend from suitable testing circuits which may include indicator lights in a housing 190 which may be located remote from the underside of the board for maximum operator convenience. The wires 186 extend to connectors 184 which may be identical to the previously identified connectors 2. The contact terminals in the con nectors 184, engage the conductors 102 on the printed circuit boards and, since these conductors extend to and contact the terminals in the connectors 2 on the upper surface of the board which are now part of the completed harness. the harness can be tested by merely energizing the testing circuits in the housing 190. Any opens or misplaced wires in the harness can be readily detected during this very brief testing procedure and the harness can be repaired or reworked in a very brief time. The practice of the invention thus eliminates the need for a time-consuming and costly final electrical test which is usually made by plugging the connectors of the harness with connectors or printed circuit boards of the testing apparatus.
It is desirable to have the capability in the apparatus to accommodate varying sizes of connectors, that is connectors having different numbers of contact terminals therein. If, for example, it is desired to connect wires to a relatively smaller connector 2A (FIG. 8) then the connectors previously described, it is merely necessary to remove the printed circuit board 102 from the apparatus and substitute a printed circuit board 102 which has a tongue 180 extending from its upper edge as viewed in FIG. 8. This tongue is dimensioned to fit into the mating face of the connector 2A and to center and support it in the tool or apparatus in the manner previously described. It will thus be apparent that the apparatus can be modified to accept varying sizes of connectors by simply changing the printed circuit board.
The board is changed by simply opening the carrier frame until its accurate movement is stopped by the latch dog 124. The lever 114 which engages this latch dog is then depressed so that disengagement from latch dog 124 takes place and the carrier is swung through a further counterclockwise arc until the slots 96 extend vertically upwardly. The printed circuit board 98 is then swung normally of its own plane until the ears are in alignment with the slots 96. The board can then be moved upwardly with the ears biasing through the slots and the printed circuit board 980 can be similarly assembled to the carrier.
The invention presents several salient features and advantages which may be employed with beneficial re sults individually or in combination with each other in the harness making art and in processes where wires are simply being connected to the terminals in a single connector. For example, the printed circuit board 98 serves as a support for the connector to which wires are being connected and can be replaced to accommodate different sizes of connectors as noted above. Under some circumstances, it may not be required that the electrical connections be tested at the time the wires are inserted into the terminals and under such circumstances, the panel-like member can be in the form of a simple board which has supporting means for the connector. This feature of the invention may be used in a wire inserting apparatus which is not specifically intended for use in the harness making art but it is used only to connect wires in a cable to the terminals in a connector.
Under other circumstances, it may be desirable to test the connector electrically even though the apparatus is not being used for harness making as described above. It will be apparent that such electrical tests can be conducted by the practice of the invention where individual wires are being connected to terminals in a connector and the wires are not part of an electrical harness as disclosed herein.
Finally, the testing procedure disclosed herein may be used with other types of connectors such as connectors of the type disclosed in US. Pat. No. 3,760,335. To carry out such electrical tests, the connector to which wires are being connected would be mated with a complementary connector would have wires extending from its terminals to a test apparatus as explained above. Such in situ electrical testing can be carried out with wire inserting apparatus of types other than that shown in the instant application, for example, wire inserting apparatus of the type shown in US. Pat. No. 3,758,935 and 3,766,622.
