Abstract

An assembly comprising a cable terminator comprising an elongate wire guide comprising a top end and four conductor pair receiving channels, and a securing cap configured for installation over the top end and comprising four pairs of piercing contacts exposed on an upper surface is disclosed. Each pair of the piercing contacts are interconnected with a respective conductor pair, and a coupler connector comprising a forward surface comprising an RJ-45 compatible socket, wherein tines are exposed within the socket and a rearward surface comprising a cable terminator receiving socket. Pairs of contacts are exposed on an end wall of the socket. Each of the tines is interconnected with a respective one of the contacts. When the cable terminator is inserted into the cable terminator receiving socket, the upper surface of the securing cap is positioned against the end wall and each of the piercing contacts comes into contact with a respective one of the contacts, thereby interconnecting each of the tines with one of the conductors.

Claims

1. An assembly for terminating a cable comprising four pairs of conductors, the assembly comprising:

a cable terminator comprising;

an elongate wire guide comprising a top end and four conductor pair receiving channels; and

a securing cap configured for installation over said top end and comprising four pairs of piercing contacts exposed on an upper surface thereof, wherein each pair of said piercing contacts are interconnected with a respective conductor pair; and

a coupler connector comprising a forward surface comprising an RJ-45 compatible socket disposed therein, wherein eight tines are exposed within said RJ-45 compatible socket and a rearward surface comprising a cable terminator receiving socket disposed therein, wherein four pairs of contacts are exposed on an end wall of said socket, and further wherein each of said tines is interconnected with a respective one of said contacts;

wherein when said cable terminator is inserted into said cable terminator receiving socket, said upper surface of said securing cap is positioned against said end wall and each of said piercing contacts comes into contact with a respective one of said contacts, thereby interconnecting each of said tines with a respective one of the conductors.

2. The assembly of claim 1, wherein each of said conductor pair receiving channels comprises a first portion running a long a length of said wire guide, a second portion in said flat end and at right angles to said first portion and a curved portion interconnecting each of said first portions with a respective one of said second portions.

3. The assembly of claim 2, wherein each second portion is arranged along a respective axis and further wherein each of said axes intersects another of said axes at right angles.

4. The assembly of claim 1, wherein said wire guide further comprises a plurality of tabs protruding from a wire guide side and said cap comprises plurality of slots in a cap side and further wherein said tabs engage respective ones of said slots when said cap is placed over said wire guide, thereby retaining said cap against said wire guide.

5. The assembly of claim 1, wherein said wire guide further comprises a cable receiving cuff opposite said flat end and defining a cable receiving opening opposite said flat end.

6. The assembly of claim 5, wherein said cable receiving opening is substantially circular.

7. The assembly of claim 5, wherein said cuff is comprised of four elongate flexible fingers, each of said fingers separated from an adjacent flexible finger by one of said four conductor pair receiving slots and comprising a transverse crimp receiving notch on an outer surface thereof.

8. The assembly of claim 7, wherein the cable comprises a jacket and each of said elongate flexible fingers combine to define a cylindrical inner surface adapted for gripping the jacket.

9. The assembly of claim 7, wherein each of said fingers is separated from an adjacent one of said fingers by one of said four conductor pair receiving slots.

10. The assembly of claim 8, further comprising a band and wherein each of said fingers comprises a transverse band receiving notch on an outer surface thereof, wherein securing said band in said band receiving notches forces said flexible fingers inwards such that said cylindrical inner surface grips the cable jacket.

11. A method for terminating a cable comprising a jacket surrounding four pairs of conductors, the method comprising:

removing a length of said jacket from an end of said cable to expose a free end of each of said pairs of conductors;

feeding said free ends in a respective conductor pair receiving slot in a wire guide;

placing a cap over a top end of said wire guide, said cap comprising a plurality of pairs of piercing contacts arranged along an upper surface thereof, wherein when said cap is installed on said top end, each of said pairs of piercing contacts align with a respective pair of conductors;

piercing an insulation of each of said conductors with a piercing first end of an aligned one of said piercing contacts, wherein a contacting second end of each of said piercing contacts remains exposed on said upper surface;

inserting said cap and said wire guide into a cap and wire guide receiving socket in a rearward surface of a coupler connector such that each of said contacting second ends of said piercing contacts comes into contact with a respective one of eight contacts exposed on an end wall of said cap and wire guide receiving socket, said coupler connector further comprising a forward surface comprising an RJ-45 compatible socket disposed therein, wherein eight tines are exposed within said RJ-45 compatible socket and each of said tines is interconnected with a respective one of said contacts.

12. The method of claim 11, further comprising using a tool configured to receive said cable, cap and wire guide to move said piercing contacts relative to said cap such that they pierce an insulation of said conductors.

13. The method of claim 11, wherein each of said conductor pair receiving slots comprises a first slot portion running substantially in parallel to a length of said wire guide, a second slot portion at right angles to said first slot portion and exposed at said top end and a curved portion interconnecting said first and second slot portions, and further wherein said feeding comprises feeding each of said free ends into a respective one of said first slot portions, over a respective one of said curved portions and into a respective one of said second slot portions.

14. The method of claim 13, wherein each of said second slot portions ends at a side edge of said wire guide, and wherein prior to said cap being placed over a top end of said wire guide, said free ends are trimmed such that they are flush with said side edge.
