Abstract

An assembly comprising a cable terminator comprising a wire guide, a cube shaped securing cap comprising an open end for installation over the wire guide, and pairs of piercing contacts for piercing respective conductors of the cable. When assembled, an outer end of each of the piercing contacts is exposed on an outer surface of a respective securing cap sidewall. The assembly also comprises a coupler connector comprising one of a modular (for example RJ-45 compatible) socket or a modular (for example RJ-45 compatible) plug, a rearward surface comprising a cable terminator receiving socket, wherein pairs of contacts are exposed along at least one side wall of the socket, and further wherein each of a plurality of the tines in the modular socket or the terminal contacts of the plug is interconnected with a respective one of the contacts.

Claims

1. An assembly for terminating an end of a cable, the cable end stripped to expose lengths of four twisted pairs of conductors, the assembly comprising:

a wire guide comprising a housing defining a pair of inner holes and a pair of outer guides, two opposite outer sides and four elongate parallel conductor pair receiving slots, two of said slots exposed side by side on each of said two opposite outer sides, each of said slots interconnected with a respective one of said pair of inner holes and said pair of outer guides;

a securing cap comprising an open end sized for snug installation at least partially over said wire guide opposite outer sides, a pair of opposed sidewalls each comprising two pairs of piercing contact receiving slots therein; and

a plurality of pairs of piercing contacts, each of said pairs of piercing contacts insertable into a respective pair of said piercing contact receiving slots;

wherein when assembled each of the lengths of twisted pairs of conductors is received in a respective one of said slots via said interconnected one of said pair of inner holes and said pair of outer guides and each of said opposed sidewalls is positioned adjacent a respective one of said opposite outer sides such that a piercing end of each of said piercing contacts is positioned opposite a respective one of said slots and the received length of twisted pair of conductor and in contact with the respective conductor and an outer end of each of said piercing contacts is exposed on an outer surface of a respective securing cap sidewall.

2. The assembly of claim 1, wherein said wire guide and said cap are of generally cubic form.

3. The assembly of claim 1, wherein said pair of inner holes and said pair of outer guides are elongate and generally in parallel to the cable axis when assembled.

4. The assembly of claim 1, wherein said wire guide further comprises a cable end receiving region adjacent an inlet to each of said pair of inner holes and said pair of outer guides.

5. The assembly of claim 1, wherein when assembled a direction of each conductor in its respective one of said pair of inner holes and said pair of outer guides is substantially reversed to a direction of the conductor in its respective slot.

6. The assembly of claim 1, wherein each of said slots comprises a raised ridge along a centerline thereof.

7. The assembly of claim 1, further comprising a rounded edge interconnecting each of said pair of inner holes and said pair of outer guides with said respective one of said slots.

8. A method for terminating an end of a cable comprising four twisted pairs of conductors surrounded by a jacket, lengths of the four twisted pairs of conductors exposed beyond an end of the jacket, the method comprising:

threading each of said exposed lengths of twisted pairs of conductors into a respective one of a pair of inner holes and a pair of outer guides of a wire guide, each of said inner holes and outer guides interconnected with one of four parallel conductor pair receiving slots, two of said slots exposed side by side on each of two opposed outer sides of said wire guide;

unwinding at least a piercing portion of each of the four exposed lengths of twisted pairs;

bending each of the four exposed lengths of twisted pairs of conductors such that each conductor of said piercing portion is arranged side by side and in parallel in said interconnected one of said four parallel conductor pair receiving slots;

securing a cap at least partially over said opposite outer sides and such that each of a plurality of piercing contact receiving slots in said cap is aligned with a respective one of said piercing portions; and

inserting a piercing contact via each of said piercing contact receiving slots into a respective one of said piercing portions while leaving an outer end of each of said piercing contacts exposed on an outer surface of a respective securing cap sidewall.

9. The method of claim 8, wherein said cap comprises an open end sized for snug installation over said wire guide.

10. The method of claim 8, further comprising prior to said threading straightening the exposed lengths of the four twisted pairs of conductors.

11. The method of claim 8, wherein each of said piercing portions is received snugly in said slot.

12. The method of claim 8, further comprising stripping the end of the jacket to expose lengths of the four twisted pairs of conductors.

13. The method of claim 8, wherein said inserting comprises receiving the end of the jacket within a cable receiving region defined by said wire guide.
