Communications jacks having contact wire configurations that provide crosstalk compensation
First Claim
1. A communications jack, comprising:
- a housing having a plug aperture that is configured to receive a mating plug that is inserted along a horizontal plug axis;
a generally vertically-oriented wiring board that is mounted substantially normal to the horizontal plug axis;
a first contact wire and a second contact wire that form a first differential pair of contact wires, the first and second contact wires each having a fixed portion that is mounted in the vertically-oriented wiring board and a deflectable portion that is at least partially positioned in the plug aperture; and
a third contact wire and a fourth contact wire that form a second differential pair of contact wires, the third and fourth contact wires each having a fixed portion that is mounted in the vertically-oriented wiring board and a deflectable portion that is at least partially positioned in the plug aperture;
wherein at least a portion of the first differential pair of contact wires is positioned between the contact wires of the second differential pair of contact wires in a plane that is normal to the vertically-oriented wiring board;
wherein the deflectable portions of the third and fourth contact wires include a crossover;
wherein the fixed portions of the third and fourth contact wires are spaced farther apart vertically than are the fixed portions of the first and second contact wires.

Abstract
Communications jacks include a housing having a plug aperture that is configured to receive a mating plug that is inserted along a horizontal plug axis and a vertically-oriented wiring board that is mounted substantially normal to the horizontal plug axis. First through fourth contact wires are mounted in the vertically-oriented wiring board, with the first and second contact wires forming a first differential pair of contact wires and the third and fourth contact wires forming a second differential pair of contact wires. At least a portion of the first differential pair of contact wires is positioned between the contact wires of the second differential pair of contact wires, and deflectable portions of the third and fourth contact wires include a crossover. Additionally, the fixed portions of the third and fourth contacts are spaced further apart vertically than are the fixed portions of the first and second contacts.
