Abstract: A plug and jack connector for multi-conductor cable is provided with shielding to attenuate EMI/RFI radiation passing into and out from the jack and/or plug and an arrangement for grounding electrostatic charge carried on the cable shield. The jack is designed for insertion into a printed circuit board and includes a front housing part formed of electrically conductive material, an insulative rear housing part and a plurality of contacts having leads which are totally enclosed within the housing. The front housing part is the shielding member of the jack and is adapted to be grounded, such as by mounting on a chassis. The plug is of modular construction. Shield apparatus surrounds the plug to provide interference attenuation and extends into a cable shield terminating portion of the plug cavity to electrically engage a conductive ferrule applied around the cable which engages the cable shield to provide a path for grounding the cable shield.

Abstract: A jack adapted for connection to a printed circuit board or the like for a modular plug connector having a cord shield terminating contact includes a housing formed of plurality of jack parts adapted to interfit with each other to define an elongated receptacle for receiving the connector. One of the jack parts constitutes a grounding and shielding part formed of electrically conductive material and having top, bottom and side walls defining a closed, sleeve-like member. Each of the walls has a longitudinally extending inner surface at least a substantial portion of which bounds the plug receptacle so that a substantial portion of the receptacle is bounded on all of its sides by the electrically conductive material of the grounding and shielding part. The top, bottom and side walls of the grounding and shielding parts substantially surround the plug receiving receptacle on all of its sides substantially over its length.

Abstract: A jack for modular plug connectors designed for connection to a printed circuit board includes a housing formed of three parts which when interfitted define a receptacle for receiving a modular plug connector which terminates a multi-conductor cord. A plurality of jack contacts are held through the interfitting relationship of the various housing parts in a manner such that the jack contacts are entirely enclosed within the housing except for the projecting portions thereof which are adapted to be inserted into the printed circuit board. The plug receiving receptacle is partially defined by a surface adapted to provide a backing support for the jack contact portions engaged by the contact terminals of the modular plug connector.

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.

Abstract: A modular plug connector is provided with a device for terminating the shielding of a cord to prevent or at least substantially reduce the radiation of electromagnetic and radio frequency interference from the region of the connector, such as when the cord is used in the transmission of high frequency digital-based data. The device also advantageously provides for the isolation and grounding of electrostatic discharge. The shield terminating device in one embodiment is constituted by a contact passing through the housing of the modular plug connector into the cord-receiving cavity of the connector housing so as to electrically engage the shield sheath of the cord.

Abstract: An improved modular plug connector is provided with a contact as a part of the connector itself for terminating the foil shield of a cord to prevent or control the radiation of interference-causing electromagnetic and radio frequency signals from the region of the connector, such as when the cord is used in the transmission of high frequency digital-based data. The connector incorporating the shield terminating contact also advantageously provides for the isolation and grounding of electrostatic charge. The shield terminating contact is constituted by a contact pin which passes through a side wall of the connector housing into the cord-receiving cavity to electrically engage the cord shield.
