Abstract

Patch cords include a communications cable that has a first conductor and a second conductor that form a first differential pair, and a third conductor and a fourth conductor that form a second differential pair and a plug that is attached to the communications cable. The plug includes a housing that receives the communications cable, first through fourth plug contacts that are within the housing, and a printed circuit board. The printed circuit board includes first through fourth conductive paths that connect the respective first through fourth conductors to respective ones of the first through fourth plug contacts. The plug further includes a first conductive shield that extends above a top surface of the printed circuit board that is disposed between the first differential pair and the second differential pair.

Claims

1. An RJ-45 communications plug, comprising:

a housing;

a printed circuit board within the housing;

a lossy dielectric material between at least one side of the printed circuit board and the housing.

2. The RJ-45 communications plug of claim 1, wherein the lossy dielectric material comprises a carbon loaded foam.

3. The RJ-45 communications plug of claim 1, wherein the lossy dielectric material is injected within the housing.

4. The RJ-45 communications plug of claim 1, wherein the lossy dielectric material comprises an injectable and curable material.

5. The RJ-45 communications plug of claim 1, wherein the lossy dielectric material substantially fills the open area within the housing.

6. The RJ-45 communications plug of claim 1, in combination with a communications cable to provide a communications patch cord.
