Abstract

A network connection system for connecting computer and telephone network components, including a twisted pair cable termination connector for use with twisted pair cable, the twisted pairs being arranged within an outer cable jacket such that each twisted pair substantially occupies a cross sectional quadrant of the cable. The connector includes a pair separator having four passages arranged to substantially keep the four twisted pairs in a quadrant relationship relative to one another and in which the twisted relationship of each twisted pair is maintained substantially until the conductors are electrically terminated to their respective conductive contact member; and a mating component adapted to couple with the twisted pair cable termination connector.

a twisted pair cable termination connector for use with twisted pair cable having four twisted pairs of conductors, the twisted pairs being arranged within an outer cable jacket such that each twisted pair substantially occupies a cross sectional quadrant of the cable, the connector comprising;

a conductive contact member for each conductor to which the conductors are couplable in electrically conductive relationship;

a pair separator having four passages arranged to substantially keep the four twisted pairs in a quadrant relationship relative to one another and in which the twisted relationship of each twisted pair is maintained substantially until the conductors are electrically terminated to their respective conductive contact member;

a first pair guide formed of a dielectric material that defines four channels therethrough, the four channels including at least one crossing channel that guides one of the twisted pairs to a crossed location relative to other twisted pairs; and

a mating component adapted to couple with the twisted pair cable termination connector.

2. The network connection system as claimed in claim 1, further comprising

a second pair guide and in which the first pair guide and the second pair guide have opposed handedness with regard to their respective crossing channels.

3. The network connection system as claimed in claim 1, in which the conductive contact members of the twisted pair cable termination connector comprise insulation displacement contacts having a first forked end and a second forked end in which the first forked end is adapted to pierce insulation of one of the twisted pair conductors and to receive and grip a conductive core of the twisted pair conductor in mechanical and conductive relation and in which the second forked end is adapted to grippingly receive a blade shaped contact in mechanical and conductive relation.

4. The network connection system as claimed in claim 1, in which the pair separator of the twisted pair cable termination connector further comprises at least one tower, one of the four passages passing through the tower such that one of the twisted pairs can pass through the tower and its two conductors can be terminated to the conductive contacts located substantially at an end of the tower.

5. The network connection system as claimed in claim 1, in which the pair separator of the twisted pair cable termination connector further comprises a wall, the wall being located substantially adjacent to a termination of one of the four passages and supporting at least two of the conductive contacts such that one of the twisted pairs can pass through the passage and be terminated to the conductive contacts substantially at an end of the wall.

6. The network connection system as claimed in claim 1, in which the mating component comprises a connector to RJ jack comprising a female RJ interface and contacts that are releasably couplable to the conductive contact members.

7. The network connection system as claimed in claim 1, in which the mating component comprises a connector to connector jack adapted to couple two twisted pair cable termination connectors together.

8. The network connection system as claimed in claim 1, in which the four passages are located in the pair separator such that one of each four passages is located adjacent to a wall of the pair separator that extends outwardly from the pair separator.

9. The network connection system as claimed in claim 1, in which the pair separator has four corners and in which the four passages are located in the pair separator such that each of the four passages is located adjacent to one of the four corners of the pair separator.

10.

11. The network connection system as claimed in claim 1, in which the pair separator presents a multilobed entrance having multiple lobes to receive the twisted pairs, each of the lobes transitioning within the pair separator into one of the four passages.

12. The network connection system as claimed in claim 1, in which the pair separator and the mating component have mating alignment features that permit the pair separator and the mating component to be coupled to one another only in a desired orientation.
