Abstract

A communication plug having a plug body and a plurality of contact pairs at least partially within the plug body, the contact pairs including an inherent asymmetric coupling between individual contacts of one of the contact pairs and other individual contacts of another of the contact pairs. Second asymmetric coupling elements are connected between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. The second asymmetric coupling elements, when combined with the inherent asymmetric coupling, provide a balanced symmetric coupling between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs.

First claim

The invention claimed is:

1. A communication plug for making electrical contact between a communication cable and a communication jack, comprising:
a plug body having a cavity for receiving the communication cable, wherein the communication cable enters the plug body along an axis;
a molded body contained within the plug cavity;
a circuit board wrapped around the body;
first contacts for making electrical contact between traces on the circuit board and the cable; and
second contacts for making electrical contact between the traces on the circuit board and contacts on a jack to which the plug is interfaced.

2. The communication plug of claim 1 , wherein the circuit board is a flexible printed circuit board.

3. The communication plug of claim 2 , wherein the molded body has a generally triangular cross-section, and wherein the flexible circuit board is wrapped around the body so that first and second ends of the flexible circuit board are located in the plug body closest to where the communication cable enters the cavity.

4. The communication plug of claim 3 , wherein a first subset of IDCs are press-fit into holes in the body at the first end of the circuit board and second subset of IDCs are press-fit into holes in the body at the second end of the circuit board, and wherein the first and second subsets of IDCs make electrical contact with wires in the communication cable and with traces on the circuit board.

5. The communication plug of claim 1 , wherein the second contacts are contact pads disposed on the circuit board.

6. The communication plug of claim 1 , wherein the circuit board comprises a common mode choke for each pair of the traces on the circuit board.

7. The communication plug of claim 1 , wherein the circuit board comprises a plurality of surface mount chokes positioned in pockets in the body.
