Abstract:
An RJ45 communication jack has a housing with a top, bottom, front, and back. A foil is immediately adhered to and partially covers the housing. A top or bottom of the housing is covered by a first portion and a second portion of the foil wherein the first portion and the second portion are separated by a nonconductive gap. The gap extends from the front of the housing to the rear of the housing.
Abstract:
This application describes a jack for improving crosstalk attenuation. The jack has a housing, a foil at least partially surrounding the housing, a printed circuit board, and at least one pair of insulation displacement contacts and vias. Each pair of insulation contacts and vias are associated with a differential signal. A conductive trace stub is routed on the printed circuit board near the edge of the board proximate to the foil in order to at least partially balance the coupling from one of the insulation displacement contacts and vias of a pair to the foil with the other insulation displacement contact and via of the pair by electrically connecting the trace stub to the via that is further from the foil.
Abstract:
The present invention generally relates to the field of network communications, and more specifically to networks for crosstalk reduction/compensation and communication connectors which employ such networks. In an embodiment, the present invention is an RJ45 jack with an orthogonal. compensation network to meet CAT6A or higher performance standard. For the 3:6-4:5 wire-pair combination, the orthogonal compensation network begins in the jack nose (plug interface contact (PIC)) section, and utilizes a flexible printed circuit board in the nose section, split PIC contacts in the rear nose, and circuitry in the rigid printed circuit board to create the orthogonal compensation network.

A top or bottom of the housing is covered by a first portion and a second portion of the foil wherein the first portion and the second portion are separated by a nonconductive gap. The gap extends from the front of the housing to the rear of the housing. With such foils placed on each one of a series of adjacent jack housing, common mode noise caused by capacitive coupling between adjacent ones of the foils is reduced.
