The invention relates to an electrical connector, particularly for splicing together related ones Head of pairs of conductors.

Frequently associated head of conductor pair bundles, z. B, of telephone cables, to be spliced, and Due to the large number of several thousand individual connections to be made, it is important that each

A known electrical connector made of a molded plastic housing includes a towards itself a housing end opening connector receiving cavity, an electrical connection member stamped and formed from a piece of sheet metal, the first and second parallel conductor receiving slots that are lateral to their axes of one another are spaced and the ends of which are open in the axial direction to the receiving cavity, wherein a first wall each receiving cavity with two conductor receiving slots is formed, which are aligned with the corresponding slots of the associated connecting member, and wherein the slots have open axial ends at the end of the housing.

A disadvantage of this known connector is that in handling and positioning of the two associated head of two pairs of conductors to be spliced result in difficulties because there is a risk that the first conductors will emerge from the slots again before the second Conductors are spliced to them, or comb-like jigs must be used to define both pairs of conductors for simultaneous splicing.

The object of the invention is to provide an electrical connector which avoids the aforementioned disadvantages and in particular for use in a semi-automatic conductor splicing device according to FIG Parallel filing by the applicant on the same date (US filing number 576 932; our AMP 3595 file) is trained.

The electrical connector according to the invention is characterized in that at the opposite end of the housing a second cavity is formed which receives a second electrical connection member that first and second conductor receiving slots arranged identically on a wall of the second cavity and the second terminal member have, so that the connecting members abut with the rear sides, and that the cavity walls Have resiliently deflectable members, each of which has a conductor holding constriction in one Wall slot defined between opposite ends of each connector slot.

The first mated conductors are simultaneously inserted into opposite ends of the connector and held securely in the slots during the insertion of the second associated conductor of the conductor pairs.

Embodiments of the invention are described below explained in more detail with reference to the drawing. Show it:

A connector 10 consists of a one-piece plastic cast insulating housing 11 and two metallic connecting members 12, which are in a snug fit in cavities 13, which are formed in opposite housing ends are received.

Each connecting member is channel-shaped in section and has Sidewalls formed with spaced-apart pairs of conductor receiving slots 14 and 15 and a pair of intermediate slots 17 are designed so that the walls of the conductor receiving slots can be bent independently of one another are. The conductor receiving slots of each pair are aligned with each other and have different widths, which results in a conductor core contact and strain relief.

Upper and lower side walls 19 and 20 of each housing cavity 13 also have slots 21 and 22, respectively, which are aligned with the conductor receiving slots 14 and 15. The upper side walls are cut out at 23 for Formation of resiliently flexible fingers 24, which extend obliquely over the slots 14 and 15 and their free ends lie between the ends of the slots. The inner ends 25 of the slots 21 are enlarged and define a constricting flexible divider member 26. The slots 21 diverge at their Outer ends and form step-like mouths 27.

The housing base 29 has a reduced width so that a conductor insertion tool is provided at each end of the housing Has access.

The connector housing can be produced in strip form, with a perforated carrier strip 31 made of Mylar (polyester

foil) or a suitable plastic, ζ. B. Eapton (thermally stable polyimide), or metal through the mold passing a molding machine and molding the housings onto the strip; the mold cavities have Recesses, so that the casting compound can flow through the holes in the carrier strip, whereby to the underside of the carrier strip lugs 32 are formed will. These lugs hold the connector securely on the strip while allowing ease of use Separating from the strip using the device mentioned at the beginning.

Corresponding conductors of conductor pairs can be spliced using this device. While Each conductor is pressed into the housing slots 21 by an insertion plunger, the inter alia. by the Divider member 26 and the side walls formed by the fingers 24 are resiliently bent apart (see FIG. 6), see above that the conductor can enter the slots 14 or 15 of the connecting member. Penetrate during insertion the slot walls adjacent to the fingers 24 insulate the conductors and establish an electrical connection with the conductor core while the other aligned slots grip the insulation or penetrate them to provide strain relief. When the head is fully in the slots is inserted, the finger 24 springs back so that its free end lies over the conductor and it in the slot holds (see. Fig. 7). The strip is then indexed to splice the next pair of conductors.

The connectors can be made in a very small size (e.g. 12.7 x 7.3 x 6.6 mm) so that they can be spliced of a cable take up very little space. The flexible pingers not only provide strain relief of the electrical connection in the axial direction of the slot, but also contribute to the "Mschlussglieder after making the connection in the housing .. to be held. Because the connecting members in the cavities are held, they are isolated from the terminations of adjacent connectors when splicing the splices after connecting the cable are bundled together and the individual conductors of the spliced pairs be determined with each other; this is important for quick repairs. The adaptation of the connector strip feed allows a large number of isolated connections to be made automatically by unskilled Operator can be produced, with little fatigue occurring in the operator; this is then very "advantageous if several thousand individual connections are made when splicing two telephone cables are. The handling of the ladder is also made easier because the ladder of each pair extends from extend one end of the cable, using the device mentioned at the same time with the connecting members are connectable.

The second embodiment according to Pig. 8 is particularly advantageous for making branch connections. The connector is similar to the first exit
