摘要:
A communication jack that withstands insertion of a communication plug with which the jack is not configured to mate without being damaged. The communication jack comprises a wire board and a number of contact wires that extend above the wire board and that are electrically coupled to respective contact regions on the wire board at first ends of the contact wires. The contact wires having second ends that are freely disposed for making electrical connections with corresponding contact wires of a mating communication plug. Each of the freely disposed ends of the contact wires are cantilevered from respective fist ends of the contact wires such that the contact wires are capable of being deflected when the freely disposed ends wipe against respective contact wires of the mating communication plug. Some of the freely disposed ends are deflected to a lesser degree than at least two opposing, outer freely disposed ends when the freely disposed ends wipe against and are deflected by respective contact wires of a mating communication plug. The freely disposed ends that are deflected to a lesser degree than the opposing, outer freely disposed ends abut a surface of the wire board. The configuration of the wire board is such that the opposing, outer freely disposed ends avoid abutting the surface of the wire board when the freely disposed ends wipe against and are deflected by respective contact wires of a mating communication plug.

A communication jack connector includes a wiring board having a front region, and a number of contact wires for engaging and making electrical connections with corresponding terminals of a conforming plug connector. The contact wires have free ends formed to be deflected resiliently in a direction toward the front region of the wiring board when engaging the plug connector. At least one clearance opening is formed in the wiring board at a location where the free end of a corresponding contact wire would otherwise contact an upper surface of the board when deflected by the plug connector. The clearance opening is dimensioned so that part of the free end of the contact wire deflects into the opening a certain distance from the upper surface of wiring board while the contact wire maintains sufficient resilient force to connect electrically with the corresponding terminal of the plug connector.

A back-end variation control cap configured for use with a jack module including a plurality of insulation displacement connectors, the cap being configured for routing a plurality of twisted conductor pairs. The cap includes an upper portion, a bottom portion, a plurality of twisted pair channels extending between the upper portion and the bottom portion, and a pair of opposed end walls, each of the end walls including a plurality of wire constraints disposed thereon. Each wire constraint has opposed surfaces configured to retain one of the conductors and each twisted conductor pair extends through one of the twisted pair channels and the conductors of the twisted conductor pairs are disposed in the plurality of wire constraints such that each conductor is aligned with one of the insulation displacement connectors when the bottom portion is disposed adjacent the jack module.

A patch panel with pivoting bracket assembly is provided which reduces the tendency for optical fiber patch cords to entangle or snarl in front of the couplings of the patch panel. In a preferred embodiment, the patch panel incorporates a plurality of couplings, with each of the couplings configured to optically communicate with an optical fiber cable. Each of the couplings is moveable between a patching position and a stowed position so that, in the patching position, each of the couplings are configured to receive a patch cord connector in a first direction, thereby allowing the patch cord to optically communicate with an optical fiber cable. In the stowed position, the cables of patch cords engaging the couplings are directed toward the mounting surface in a second direction. Preferably, the first direction and the second direction are oriented toward the mounting surface. A method aspect of the invention is also presented.

A patch panel with patch cord plug keyway incorporates at least one jack. The jack communicates with a transmission medium, such as a cable, with the jack including a plug-receiving cavity and a keyway. The plug-receiving cavity is configured to receive and securely mount the plug of a patch cord so that the transmission medium cooperating with the jack electrically communicates with the patch cord when the plug is in an engaged position. The keyway is formed through the jack and communicates with the plug-receiving cavity. Additionally, the patch cord plug incorporates a key which engages the keyway of the jack. So configured, the key assists a technician in aligning the patch cord plug with the plug-receiving cavity of a jack during patching operations. In a preferred arrangement, they key is formed on a rotatable lever which places the plug in a locking and unlocking orientation.

A preferred embodiment of a strain relief apparatus includes a body member incorporating a first end for facing the cable-receiving end of a connector, a second end for facing away from the cable-receiving end of a connector, and a flap extending from the body member. The flap is movable between an unbiased position and a forwardly-displaced position so that in its unbiased position the flap is oriented in an overlying relationship with a trigger of the connector. In its forwardly-displaced position, the flap urges the trigger toward the bottom side of the connector such that the trigger urges a latch of the connector to its unlatched position. Preferably, the flap has a handle extending therefrom, with the handle being configured so that a technician can reposition the flap from its unbiased position to its forwardly-displaced position as well as manipulate the connector, such as during patching operations.
