Abstract

A method for terminating a telecommunications cable where the cable comprises a plurality of twisted pairs of wires is disclosed. The method comprises providing an interconnection module comprising a pair of contacts for each of the twisted pairs, aligning the end portions and interconnecting each of the aligned end portions with a corresponding pair of conductive contacts. Aligning comprises arranging the end portions such that when connected to the contact pairs, the twisted pairs remain uncrossed.

Claims (24)

1. A method for terminating a telecommunications cable, the cable comprising four twisted pairs of wires arranged in a generally parallel relationship to a common axis, each of the twisted pairs having an exposed end portion, the method comprising:

providing an interconnection module comprising four pairs of substantially flat Insulation displacement contact IDC terminals, a corresponding one of said four pairs of Insulation displacement contact IDC terminals for terminating each of the twisted pairs, wherein each Insulation displacement contact IDC terminal of each pair of said four pairs of Insulation displacement contact IDC terminals lie in the same plane;

aligning the end portions; and

interconnecting each of the aligned end portions with said corresponding pair of Insulation displacement contact IDC terminals;

wherein said aligning the end portions comprises arranging the end portions such that when connected to their corresponding Insulation displacement contact IDC terminal pairs, said twisted pairs remain uncrossed.

2. The method of claim 1 , further comprising, prior to interconnecting each of the aligned end portions:

providing a wire lead guide comprising of a guide body defining a plurality of non-intersecting passageways; and

inserting each of said end portions through a corresponding one of said passageways.

3. The method of claim 2 , further comprising four non-intersecting passageways through said body and further wherein each of said end portions is inserted through a dedicated one of said passageways.

4. The method of claim 1 , wherein each of said terminals comprises a bifurcated contact plate and interconnecting each of the aligned end portions comprises inserting said aligned end portions into said bifurcation.

5. The method of claim 1 , wherein the aligned end portions lie substantially in the same plane.

6. The method of claim 4 , wherein the end portions are bent substantially at right angles to the common axis prior to interconnecting each of the aligned end portions.

7. The method of claim 1 , wherein said terminals are arranged in two substantially parallel and aligned rows of terminals and wherein interconnecting each of the aligned end portions further comprises connecting every second of the aligned end portions to a pair of terminals in a different row.

8. The method of claim 1 , wherein said terminals are arranged in two substantially parallel rows of two pairs of terminals each, said rows defining an insertion region there between, and further comprising positioning the aligned end portions in said insertion region prior to interconnecting each of the aligned end portions.

9. The method of claim 1 , wherein said end portions are aligned such that adjacent end portions are connected with pairs of terminals in different rows.

10. The method of claim 1 wherein each of the twisted pairs is coded with a colour selected from the group consisting of blue, orange, green and brown and wherein each of said pairs of terminals is colour coded with a colour selected from the group consisting of blue, orange, green and brown, each of said colour coded pairs of terminals for interconnection with the twisted pair having the same colour code.

11. The method of claim 10 , wherein said colour coded pairs of terminals are arranged such that said green coded pair of terminals and said brown coded pair of terminals are on a first side of said insertion region and said orange coded pair of terminals and said blue coded pair of terminals are on an opposite side of said insertion region, said orange coded pair of terminals being opposite said green coded pair of terminals and said brown coded contact pair being opposite said blue coded contact pair and wherein the twisted pairs are distributed in an ordered sequence of blue, orange, green and brown around the common axis, and aligning the end portions further comprises arranging the end portions such that blue is adjacent to brown and green is adjacent to orange.

12. The method of claim 11 , wherein aligning the end portions further comprises arranging the end portions in the order green, orange, brown then blue.

13. The method of claim 10 , wherein said colour coded pairs of terminals are arranged such that said orange coded pair of terminals and said brown coded pair of terminals are on a first side of said insertion region and said green coded pair of terminals and said blue coded pair of terminals are on an opposite side of said insertion region, said orange coded pair of terminals being opposite said green coded pair of terminals and said brown coded pair of terminals being opposite said blue coded pair of terminals and wherein the twisted pairs are distributed in an ordered sequence of blue, orange, green and brown around the common axis, and aligning the end portions further comprises arranging the end portions such that blue is adjacent to brown and green is adjacent to orange.

14. The method of claim 13 , wherein aligning the end portions further comprises arranging the end portions in the order orange, green, brown then blue.

15. The method of claim 1 , wherein the cable is a Unshielded Twisted Pair UTP cable.

16. The method of claim 1 , wherein the cable is selected from the group consisting of Unshielded Twisted Pair cables UTP cables, Screened Twisted Pair ScTP cables and flat cables.

17. The method of claim 1 , wherein the cable is selected from the group consisting of round cables and flat cables.

18. The method of claim 1 , further comprising mounting a sleeve over each of the end portions prior to interconnecting each of the aligned end portions.
