Wire connector for telecommunications cables

The present invention relates to a wire connector for the incoming and outgoing wires of a telecommunications cable, in which the connector body (3) comprises a cover portion (1) and a bottom portion (2). For the termination of two wires (4) there is fixedly mounted a solderless, non-screwed, strip-free terminal (5) having a polytropic air gap, a resilient tab (7) having a crimped portion (6) being integrally formed at one end of said terminal (5) and the contact arms (5a) of said terminal (5) being offset relative to the cable axis at an angle of about 45 degrees. The bottom portion (2) of the connector body (3) is provided with either tubular or channel-like guide means (8, 8a) and clamping ribs (9), a cutting blade (10) for separating the cable wires being also inserted. The cover portion (1) is formed with an aperture (11) for insertion of a test prod (12).

We claim:

1. A wire connector for connecting incoming and outgoing pairs of wires of a telecommunications cable, said connector comprising: a connector body (3) consisting of a cover portion (1) and a bottom portion (2), there being fixedly mounted in said bottom portion (2) at least one solderless, non-screwed, strip-free terminal element (5) for the termination of a pair of wires (4), said terminal element comprising contact arms (5a) and a resilient tab (7) integrally formed therewith, said tab having a crimped portion (6) at the distal end thereof adapted to engagingly receive a test prod, said contact arms (5a) of said terminal element (5) being positioned at an angle of 45 degrees relative to the axis of the connecting wires; said bottom portion (2) comprises tubular guide means (8) or channel-like guide means (8a) to receive and clamping ribs (9) at the inner ends of said guide means to retain in position the incoming and outgoing pair of cable wires; a cutting blade (10) for separating the cable ends is inserted in said bottom portion (2); said cover portion (1) furthermore comprises an aperture (11) adapted to receive a test prod (12) said aperture being positioned so that upon insertion, the test prod displaces and engages said resiliently oriented crimped portion of said tab for external connection to said terminal element.

2. A wire connector according to claim 1, characterized in that insertion lugs (13) are integrally formed with the cover portion (1), said lugs being adapted to force one of the wires between each pair of said contact arms for electrical interconnection of the two wires through the terminal element, and severing of the wire ends by means of said cutting blade when said cover portion is coupled with said bottom portion.

3. A wire connector according to claim 1, characterised in that said cover portion (1) and said bottom portion (2) are joined to one another by means of an arcuate film hinge (14) and in assembled position are latched to one another by means of detents (15).

4. A wire connector according to claim 1, characterized in that the contact ends (5b) of said contact arms (5a) are angular and are supported for stabilization in guide passages (5c) formed in said bottom portion.

5. A wire connector according to claim 1, characterized in that said connector is formed with end faces (16) said end faces being provided with connecting means (17) for serially connecting a plurality of said wire connectors to form a multipoint connector.

6. A wire connector according to claim 1, characterised in that both said cover portion (1) and said bottom portion (2) of the connector body (3) are made of plastics material.
