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. A modular plug connector adapted for insertion into the receptacle of the jack includes a housing which is surrounded by a conductive collar which terminates the cord shield through the side of the connector housing. The conductive collar is adapted to engage the inner surfaces of the grounding and shielding part of the jack which itself is grounded to thereby ground the shield.

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 ad 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 conductive collar is adapted to engage the inner surfaces of the grounding and shielding part of the jack which itself is grounded to thereby ground the shield.

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. According to one embodiment, one of the jack housing parts which substantially surrounds the longitudinal extent of the modular plug connector when the latter is inserted into the plug receiving cavity is formed of a material which is electrically conductive and which provides good electromagnetic and radio frequency radiation shielding. In use, a cord shield terminating contact of the modular plug connector may contact one or both of the conductive housing part and a grounded jack contact to ground any electrostatic charge in the cord shield to prevent electrical arcing.

A contact for a telephone transmitter is formed of a single piece of electrically conductive metal with a connector portion adapted to receive a contact terminal of a conductor associated with a modular connector receiving jack within the telephone handset, a curved, flexible contact portion adapted to electrically engage the central or outer contact of a telephone transmitter and an intermediate fastening portion. The fastening portion cooperates with an opening formed in the base wall of a telephone transmitter cup to permit the contact to be affixed thereto such that the contact portion is situated within the cup to electrically engage the transmitter contact and such that the connector portion is situated beneath the transmitter cup base wall for engaging the contact terminal of the jack conductor.

Contact and terminal for telephone transmitter

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.
