Abstract
A jack for a modular plug connector which terminates an EMI/RFI shield surrounding the conductors of a cord, as well as the cord conductors themselves as is conventional, by which the electromagnetic and radio frequency signals radiated from the conductors and carried through the shield are grounded. The jack includes front and back parts connected to each other to define a rearwardly opening receptacle for a conventional multi-contact modular insert and a communicating forwardly opening receptacle for the modular plug connector. The jack is provided with a grounded contact which, upon insertion of the modular plug connector, electrically engages a shield terminating contact which forms a part of the modular plug connector to thereby electrically couple the grounded jack contact with the EMI/RFI shield surrounding the cord conductors. The front part and possibly the back part of the jack may be formed of a plastic material which provides good EMI/RFI shielding to control radiation of high frequency signals from within the jack as well as to suitably attenuate any high frequency signals radiated from equipment external to the jack passing into the connector receptacle.
