Abstract

A communication connector assembly including a wire board, and a number of elongated terminal contact wires extending above a top surface of the board. The contact wires have free end portions for making electrical contact with a mating connector, and base portions formed opposite the free end portions for supporting the contact wires on the board and for connecting the wires to conductors on or within the board. The base portions project normal from the top surface of the board. Pairs of the contact wires are coupled to one another along a first coupling region between their free end portions and their base portions and horizontal with respect to the top surface of the wire board, so that crosstalk introduced by the mating connector of a given polarity, is reduced over the first coupling region. The base portions are also configured to enter the wire board with a pattern defining one or more second coupling regions wherein the base portions are coupled to one another with a polarity opposite the given polarity, so that the introduced crosstalk is further reduced over the second coupling regions.

Claims

1. A communication connector assembly, comprising:

a wire board;

a number of elongated terminal contact wires extending above a top surface of the wire board for making electrical connections with corresponding terminals of a mating connector, wherein the contact wires include;

free end portions for making electrical contact with the mating connector;

base portions opposite the free end portions, wherein the base portions are formed to support the contact wires on the wire board and to connect the contact wires to conductive paths on or within the board, and the base portions project in a normal direction with respect to the top surface of the board;

certain pairs of the terminal contact wires are coupled to one another along a first coupling region between the free end portions and the base portions of said wires and horizontal with respect to the top surface of the wire board, wherein crosstalk of a certain polarity introduced by the mating connector is reduced over the first coupling region; and

the base portions of the terminal contact wires are configured to enter the wire board with an entry pattern that defines one or more second coupling regions wherein the base portions are coupled to one another with a polarity opposite said certain polarity so that said crosstalk is further reduced over the second coupling regions.

2. A connector assembly according to claim 1, wherein the base portions of the terminal contact wires enter the wire board at positions along four parallel rows that are perpendicular to the direction of the contact wires above the top surface of the wire board.

3. A connector assembly according to claim 2, wherein the number of said terminal contact wires is eight, and the base portions of the contact wires enter the wire board at said positions defining two parallel lines drawn diagonally through said four parallel rows.

4. A connector assembly according to claim 2, wherein the number of said terminal contact wires is eight, and the base portions of the contact wires enter the wire board at said positions defining three connected lines drawn diagonally through said four parallel rows.

5. A communication jack connector, comprising:

a jack housing having a plug opening, the plug opening having an axis and the housing being constructed and arranged for receiving a mating plug connector in the plug opening along the direction of the plug axis; and

a communication connector assembly for electrically contacting said mating plug connector when the plug connector is received in the jack housing, said connector assembly comprising;

a wire board having a front portion which is supported in the jack housing;

a number of elongated terminal contact wires extending above a top surface of the wire board for making electrical connections with corresponding terminals of a mating connector, wherein the contact wires include;

free end portions for making electrical contact with the plug connector inside the jack housing;

base portions opposite the free end portions, wherein the base portions are formed to support the contact wires on the wire board and to connect the contact wires to conductive paths on or within the board, and the base portions project in a normal direction with respect to the top surface of the board;

certain pairs of the terminal contact wires are coupled to one another along a first coupling region between the free end portions and the base portions of said wires and horizontal with respect to the top surface of the wire board, wherein crosstalk of a certain polarity introduced by the plug connector is reduced over the first coupling region; and

the base portions of the terminal contact wires are configured to enter the wire board with an entry pattern that defines one or more second coupling regions wherein the base portions are coupled to one another with a polarity opposite said certain polarity so that said crosstalk is further reduced over the second regions.

6. A jack connector according to claim 5, wherein the base portions of the terminal contact wires enter the wire board at positions along four parallel rows that are perpendicular to the direction of the contact wires above the top surface of the wire board.

7. A jack connector according to claim 6, wherein the number of said terminal contact wires is eight, and the base portions of the contact wires enter the wire board at said positions defining two parallel lines drawn diagonally through said four parallel rows.

8. A jack connector according to claim 6, wherein the number of said terminal contact wires is eight, and the base portions of the contact wires enter the wire board at said positions defining three connected lines drawn diagonally through said four parallel rows.
