LOW CROSSTALK PRINTED CIRCUIT BOARD BASED COMMUNICATIONS PLUGS AND PATCH CORDS INCLUDING SUCH PLUGS
First Claim
1. A communications connector, comprising:
- a housing;
a printed circuit board mounted at least partially within the housing, the printed circuit board including first through eighth metal-plated vias;
first through eighth contacts mounted in the first through eighth metal-plated vias, respectively, the first through eighth contacts configured as first to fourth differential pairs of contacts; and
a first conductive trace having a first curved segment that forms a first annular ring-to-via capacitor with the first metal-plated via.

Abstract
Patch cords include a cable having eight conductors that are twisted together to form four differential pairs of conductors and a plug that is attached to the cable. The plug includes a housing, a printed circuit board, and respective first through eighth plug contacts that are electrically connected to the respective first through eighth conductors via respective first through eighth conductive paths on the printed circuit board. The plug contacts are arranged in a row in numerical order. The plug includes a wire guide that has a top shelf that extends above the printed circuit board and a bottom shelf that extends below the printed circuit board. Two of the differential pairs are routed into respective first and second channels in the top shelf and the other two of the differential pairs are routed into respective third and fourth channels in the bottom shelf.

17. An RJ-45 plug, comprising:
-
a housing that receives a communications cable having first through eighth conductors; a printed circuit board that is at least partly within the housing; and first through eighth plug blades that are electrically connected to the respective first through eighth conductors of the communications cable, wherein each plug blade includes a blade portion having a bottom surface that extends along a top surface of the printed circuit board, a downwardly extending projection that is received within a respective one of the first through eighth metal-plated vias, and wherein the bottom surface of the first plug blade includes a recessed region that forms an air gap between a portion of the bottom surface of the first plug blade and a top surface of the printed circuit board when the first plug blade is mounted on the printed circuit board. - View Dependent Claims (18)
