LOW CROSSTALK PRINTED CIRCUIT BOARD BASED COMMUNICATIONS PLUGS AND PATCH CORDS INCLUDING SUCH PLUGS

摘要

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.

1. A patch cord comprising:
a communications cable that includes a first conductor and a second conductor that are twisted together to form a second differential pair of conductors, a third conductor and a sixth conductor that are twisted together to form a third differential pair of conductors, a fourth conductor and a fifth conductor that are twisted together to form a first differential pair of conductors, and a seventh conductor and an eighth conductor that are twisted together to form a fourth differential pair of conductors; and a plug that is attached to the communications cable, the plug comprising:
a housing that receives the communications cable;a printed circuit board that is at least partly within the housing;a first plug contact that is electrically connected to the first conductor via a first conductive path on the printed circuit board, a second plug contact that is electrically connected to the second conductor via a second conductive path on the printed circuit board, a third plug contact that is electrically connected to the third conductor via a third conductive path on the printed circuit board, a fourth plug contact that is electrically connected to the fourth conductor via a fourth conductive path on the printed circuit board, a fifth plug contact that is electrically connected to the fifth conductor via a fifth conductive path on the printed circuit board, a sixth plug contact that is electrically connected to the sixth conductor via a sixth conductive path on the printed circuit board, a seventh plug contact that is electrically connected to the seventh conductor via a seventh conductive path on the printed circuit board, and an eighth plug contact that is electrically connected to the eighth conductor via an eighth conductive path on the printed circuit board, where the first through eighth plug contacts are arranged in a row in numerical order;a wire guide that has a top shelf that extends above a top surface of the printed circuit board and a bottom shelf that extends below a bottom surface of the printed circuit board,wherein two of the first through fourth differential pairs of conductors are routed into respective first and second channels in the top shelf of the wire guide and the other two of the first through fourth differential pairs of conductors are routed into respective third and fourth channels in the bottom shelf of the wire guide.
