APPARATUS FOR CONNECTING CONDUCTORS TO TWO CONNECTORS WHICH ARE BACKTO BACK BACKGROUND OF THE INVENTION This invention relates to apparatus for connecting the corresponding terminals in each of two two-row connectors to each other to produce an electrical connector adapter assembly of a type which is required under some circumstances when complex electrical harnesses are coupled to each other. The invention is herein disclosed as an embodiment containing two electrical connectors of the type disclosed and claimed in U.S. Pat. No. 3,760,335. The instant application is also related to the inventions disclosed in applications Ser. Nos. 442,958, 442,959, 442,960, in that the instant embodiment has one or more structural parts which are interchangeable with the inventions shown in those applications. Also, application Ser. No. 442,959, discloses another forrn of adapter containing two electrical connectors of the type shown herein.

U.S. Pat. No. 3,760,335 discloses an improved tworow electrical connector having two rows of electrical terminals which are adapted to be connected to the conductors in a multi-conductor cable. The terminals each have a plate-like wire-receiving portion and the wires can be connected to the terminals by simply moving them laterally of their axes and into the slots in the plates in the terminals. U.S. Pat. Nos. 3,760,335, 3,758,935 and 3,766,622 show improved apparatus for inserting the wires into the slots in the plate-like sections of the terminals and simultaneously trimming the ends of the wires.

The connectors shown in U.S. Pat. No. 3,760,335 has been received very favorable and is widely used for connecting the ends of cables and in the manufacture of complex electrical harnesses. The tooling shown in U.S. Pat. Nos. 3,758,935 and 3,766,622 is also widely used to install the connectors on the ends of cables.

Connectors of the type shown in the above-identified U.S. Pat. No. 3,760,335 are provided as male and female mating connectors which are adapted to be coupled to each other. On occasion, and where previously manufactured harnesses are being assembled to each other, if frequently happens that two identical connectors (male or female) are on the ends of portions of the harness which are to be connected to each other and these portions of the harness cannot be directly coupled. This situation commonly arises where previously prepared cables which have connectors on their ends are being added to pre-existing harness systems or electrical interconnection systems. A possible solution would be to remove one of the pre-extending connectors from the harnesses and replace it with a connector which will mate with the newly added cable, however, this is a time-consuming and expensive operation particularly if it must be carried out in a wiring bay or a similar location. It is preferable to have a supply of adapters on hand each of which comprises two identical (male or female) connectors to permit coupling of the ends of two cables which also have identical connectors on their ends.

The adapter must, of course, have the corresponding terminals in the one identical connector directly connected to the corresponding terminals in the other connector and this requires crossing of the wires in the adapter for the reason that when two identical two-row connectors are positioned back to-back, their corresponding terminals can not, under any circumstances, be directly in alignment with each other. The instant invention provides an apparatus which permits the rapid assembly of such adapters by relatively unskilled labor and under circumstances which virtually precludes the possibility of errors in the wiring.

It is accordingly an object of the invention to provide an improved apparatus for the manufacture of electrical connector adapters. A further object is to provide an apparatus for the manufacture of adapters composed of two identical two-row connectors in which the terminals of one connector are directly connected to the corresponding terminals of the other connector. A further object is to provide an apparatus which is relatively simple in construction and which can be used with previously known types of apparatus for connecting wires to terminals in electrical connectors.

These and other objects of the invention are achieved in a preferred embodiment thereof, which is briefly described in the foregoing abstract, which is described in detail below, and which is shown in the accompanying drawing in which:

A connector adapter assembly in accordance with the invention (FIG. 1) comprises two two-row electrical connectors 2, 2' which are in back-to-back relationship and which have their corresponding contact terminals electrically connected to each other. Since an understanding of some of the structural features of the connectors is required for an understanding of the invention, the connector 2 will be described below to the extent necessary for such an understanding. The connector 2' is identical to the connector 2 but it is in a different orientation and its parts are identified by the same reference numerals, differentiated by prime marks, as are used in the description which follows:

The connector 2 comprises an insulating housing having a forward or mating face 4, a rearward face 6, and a flange 8 which extends radially approximately mid-way between the faces. The forward portion 10 of the housing, which is between the mating face 4 and the flange 8, is generally trapezoidal and has a longer side l2 and a shorter side 14, this trapezoidal shape being provided for polorization purposes. The flange 8 has laterally extending ends l6, 18 which are specifically identified for the reason that the orientation of the connector in the apparatus is critical as will be described below. The forward portion of the housing has a trough-like recess 20 which is adapted to receive portion of a male connector and a plurality of contact terminals are provided in the housing which have forward contact portions which extend into this recess. Each terminal (FIG. 2) extends through a cavity 24 and has a wire-receiving portion 28 which is adjacent to the rearward face 6 of the housing, the wire-receiving portions being generally U-shaped and having wirereceiving slots which receive the ends of the wires as shown in FIG. 2. The contact terminals 22 are arranged in two parallel rows identified as A and B and are further identified by position numbers, the reference numeral I in'FIG. 4 indicating the location of position number one, the reference numeral 25 indicating position number 25, numeral 26 indicating position number 26 which is below position number one in FIG. 4 and numeral 50 indicating position number 50 which is below position number 25. The intermediate number positions in the rows A, B are between those positions specifically identified in FIG. 4.

The rearward side 6 of the housing has a transversely extending rib 30 and the rows A, B are on opposite sides of this rib. In each row, adjacent contact terminals are separated from each other by barriers 32 which are integral with the housing and the ends of the rib 30 have integral therewith oversized barriers which provide laterally oppositely directed surfaces 31. The surfaces 31 merge with surface portions 33 of the rearward face and both of these surfaces serve to locate the connector in the jig as will be described below.

Turning now to FIGS. 5 and 6, the disclosed embodiment of the invention comprises a generally rectangular metallic jig plate 34 having a surface 36 herein identified as the obverse surface and a surface 38 identified as the reverse surface. The jig plate has sides 40 and ends 42 and a central opening 44 is provided which is generally H-shaped and symmetrical about its center line. Opening 46 thus has

recesses

46, 46 on each side of its center line-adjacent to theend 43 and recesses 48, 48 adjacent to the end 42. The central opposed surfaces 52 are spaced apart by a distance which is substantially equal to the distance between the surfaces 31 of the connector housing so that the connectors 2, 2' can be positioned in the jig plate as shown in FIG. 10 with the surfaces 31 of each connector against the opposed surfaces 52 and with the surfaces 33, 33' of each connector against the surfaces 54, 54' which intersect the surfaces 52 (see FIG. 7).

Wire locating means 56, 56' are provided on each of the

sides

40, 40 of the jig plate, each of these wire 10- eating means comprising a generally T-shaped block having a head portion 58, 58' on the upper surface of which there are provided spaced apart grooves or recesses 60 which are adapted to receive wires as described below. The spacing between adjacent recesses 60 is the same as the spacing between adjacent terminal positions in, the connectors.

Fixed shear members

62, 62 are provided on the obverse surface 36, each shear member comprising a flat relatively thin metal plate 64 having a depending lip or flange 66. The plate 62 has notches 68 which extend in the plate and in the flange as best shown in FIG. 9 and the inner ends of the notches in the flange provide outside edges 70 which function as fixed shearing edges in cooperation with movable shearing edge means as will be described below. The fixed shear 62 has its plate portion 64 positioned in a shallow recess adjacent to the opening 44 on the side 40 and is held in place by suitable fasteners as shown. The fixed shear 62' is a mirror image of the fixed shear 62 and is similarly mounted on the lefthand side as viewed in FIG. 5 of thc jig plate.

The jig plate is mounted on the base or platen 76 of a suitable press (FIG. 8) having a neck portion 78 and having a head portion 80 in which contains a reciprocable ram 82. The movable or upper tooling comprises a pair of tool blocks 86, 86 which are secured to a tool mounting block 84 on the ram 82. Each tool block has depending

flanges

88, 90 on its lower end and a plurality of wire inserting punches 92 mounted in the tool block between these flanges. The individual punches 92 are dimensioned to move into the wire-receiving portions 28 of the terminals and the flanges are spaced apart by a distance such that they straddle the wire receiving portions and thebarriers when the movable tooling is in the lowermost postion (FIG. 10). The outside edges 94, 94' of the flanges on the tool blocks 86, 86' serve as movable shearing edges in cooperation with the fixed shearing edges 70, 70' during downward movement to, shear the wires immediately prior to insertion into the wire-receiving portions of the terminals.

M In use, and to produce an adapter as shown in FIG. 1, it is first necessary to connect the ends of wires to the row of terminals in the connector 2 and to connect different wires to the terminals in the row A of the connector 2. This step in the process may be carried out by an apparatus of the type shown in my co-pending application Ser. No. 442,958 or by an apparatus of the type shown in US. Pat. No. 3,758,935.

The two connectors are then positioned in the jig plate as shown in FIG. 9 with the row A of terminals of the connector 2' and the row B of terminals in the connector 2 both proximate to the reverse surface 38 of the jig plate. The wires 96 which extend from the row B of terminals in the connector 2 are passed through the opening in the jig plate to the obverse side 36 and dressed leftwardly in FIG. 9 and positioned in the recesses 60 in the wire locating means 56. After this has been done, each wire will be in alignment with the terminal in the row B which corresponds to the terminal in the row B to which it was previously connected. Similarly, the wires 96' which were previously connected to the terminals in the row A of the connector 2 are pressed through the opening in the jig block and dressed rightwardly in FIG. 9 and positioned in the recesses 60 of thewire positioning means 56. These wires 96' will each be in alignment with a terminal in the row A which corresponds with the terminal in the row A to which its end has been connected. The sectional view of FIG. 9 is thus taken such that a wire extends from position 1' (row A) in connector 2' above position 1 in row A of connector 2. This view also shows a wire extending from position 25 of row B (connector 2) to and above position 26' of row B' of connector 2'.

After the wires have been positioned as shown in FIG. 9, the jig block is mounted on the press platen by suitable locating means such as locating pins (not specifically shown) so that the rows A and B will be beneath, and in alignment with the tool blocks 86, 86. The press ram is then caused to descend to (the position of jig to shear the wires by the cooperative action of shearing edges 94, 70, 94', 70, and insert the trimmed wires into the wire receiving portions of the terminals.

It will be apparent from the foregoing description that the invention provides an extremely simple and efficient apparatus for the manufacture of adapters of the type shown in FIG. 1. FIG. 7 shows that the operation of positioning the

wires

96, 96 in the wire positioning means is extremely simple and that the likelihood of a mistake on the part of the operator is remote. The procedure outlined above thus produces two identical tworow connectors with their corresponding terminal positions connected to each other which in turn can be used to connect two cables which have connectors of the same sex on their ends.

Changes in construction will occur to those skilled in the art and various apparently different modifications and embodiments may be made without departing from the scope of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only.
