ABSTRACT:
An RJ connector with integrated magnetics which incorporates a structure to eliminate aperture leakage. In one embodiment, the RJ connector includes a housing having a top portion and a bottom portion and structured and arranged to receive a plug. A plurality of contact fingers are provided in the housing for making contact with corresponding contacts in the plug. Placed on the bottom portion of the housing is a bottom shield. The bottom shield comprises an insulating material and electrically isolated sections of conductive material embedded within the insulating material. The conductive material and the insulating material form an electrostatic/electromagnetic shield on the bottom of the connector. Each section of conductive material is connected to one of the signal pins of the connector. By carefully controlling the area, shape, and/or thickness of the conducting and insulating materials within the bottom shield, and their relative positions to one another, a certain amount of electrical capacitance will be present between each of the signal pins and ground. This capacitance acts to shunt any high frequency electronic noise present on the signal lines and effectively prevents EMI from exiting the system enclosure.
