Abstract

A connector plug for interconnecting plurality of twisted pairs of wires in a cable has a body portion having a flared recess therein. A flared insert fits within the recess and has a top surface having first and second wire pair guiding channels and a bottom surface having third and fourth wire pair guiding channels extending from a cable entrance end to a contact end of the body portion. The insert has a channel defining cross-tail which is insertable into the end of the cable and the cable is crimped thereto by a crimping ring. A contact bearing contact base is mounted on the contact end of the body portion with the contacts immediately adjacent the end of the insert. Thus, the wires stay twisted from the cable to the contacts.

Claims

1. A connector for cordage having one or more twisted wire pairs, said connector comprising:

a body portion having a cable entrance end, a contact end, and a recess therein between said ends;

said contact end having a linear array of contacts across the width thereof with at least two contacts at each end of the array and at least four or more contacts intermediate the ends of the array;

said recess having a flared portion for guiding wire pairs to said contacts at the ends of the array;

an insert member in said recess and extending from said cable entrance end to said contact end immediately adjacent thereto and having a flared shape to conform the flared portion of said recess, said insert member having a top surface and a bottom surface;

one of said surfaces of said insert having first and second substantially parallel wire guide channels separated by a wall portion for guiding first and second wire pairs from said cable entrance end to said contacts intermediate the ends of the array; and

the other of said surfaces having third and fourth wire guide channels which conform to the flared shape of said insert for guiding third and fourth wire pairs from said entrance end to said contacts at the ends of the array.

2. A connector as claimed in claim 1 wherein said one of said surfaces is said top surface.

3. A connector as claimed in claim 1 wherein said one of said surfaces is said bottom surface.

4. A connector as claimed in claim 1 wherein said insert member has one end thereof adjacent said cable entrance end having a cross-tail for insertion into the end of the cable, said cross-tail defining said first, second, third, and fourth channels.

5. A connector as claimed in claim 4 wherein said first and second channels defined by the cross-tail are directed to said top surface and said third and fourth channels are directed to said bottom surface.

6. A connector as claimed in claim 4 and further comprising a crimping ring for surrounding that portion of the jacket of the cable in which said cross-tail is located.

7. A connector as claimed in claim 1 wherein said body portion has, at the contact end, an array of slots for receiving a plurality of contacts, said contacts being mounted on a contact base member and insertable in said slots.

8. A connector as claimed in claim 7 wherein said body portion has an array of a plurality of latching posts having latching projections thereon extending upward from said body portion.

9. A connector as claimed in claim 8 wherein said contact base member has an array of a plurality of openings therein through which said latching posts pass when said contacts are fully inserted in said slots.

10. A connector as claimed in claim 9 and further comprising a cover member having an array of a plurality of latching arms depending from the underside thereof, said latching arms having latching projections thereon and being spaced to pass through said openings in said contact base to latch with said latching posts on said body portion to hold said body portion, said insert, said contact base, and said cover member firmly together.

11. A connector as claimed in claim 10 and further comprising an anti-snag cover movably mounted on said body portion.
