A connector jack usable with a plug having a plurality of plug contacts. The jack includes a body having a receptacle sized and configured to receive the plug therein, a circuit board, and a plurality of contact tines extending within the receptacle. Each tine has a first end fixedly attached to the circuit board and a second free end, and is positioned in the receptacle for contact by a corresponding one of the plug contacts and moved in response thereto in a first direction as the plug is inserted into the receptacle. The jack also includes a plurality of resilient spring members extending within the receptacle, each positioned adjacent to a corresponding one of the tines to be engaged thereby when moved in the first direction by the corresponding plug contact as the plug is inserted into the receptacle, and apply a supplemental force thereto to increase contact force and tine resiliency.

Electrical connector jack

An angled patch panel having left and right end panel sections and left and right central panel sections, each section having at least one connector mounting aperture. The left central panel section and left end panel section being attached together at an angle other than 180 degrees, and the right central panel section and right end panel section being attached together at an angle other than 180 degrees. The patch panel includes left and right mounting plates, and left and right end reawardly extending extension plates. The left end panel section extends from the left end extension plate inwardly and forwardly and terminates at a first forward position facing toward the left side, and the right end panel section extends from the right end extension plate inwardly and forwardly and terminating at a second forward position facing toward the right side, and the left central panel section extends from the left end panel section inwardly and forwardly and terminates at a third forward position facing toward the left side, and the right central panel section extends from the right end panel section inwardly and forwardly and terminates at a fourth forward position facing toward the right side. The third forward position being forward of the first forward position, and the fourth forward position being forward of the second forward position.

Patch panel

A connector isolation station system includes ports to receive connectors and includes shield members. The shield members have material properties to substantially shield, attenuate, absorb, diminish, or otherwise hinder or at least partially block wireless signals and noise from impinging upon or otherwise interfering with signal transmissions occurring through the connectors located in the connector isolation station. For instance, transmissions through adjacent connectors are substantially prevented from interfering with one another.

Connector isolation station system

Implementations of a shielded connector system involve connector isolation shielding using shield enclosures to reduce crosstalk and noise transmitted between adjacent signal cable connectors. These implementations allow for manufacture of new equipment and also retrofitting of existing equipment for connector isolation shielding using standard connector configurations without specialized labor intensive terminations for cable and for connectors required of conventional approaches.

A insulation displacement connector (IDC) patch panel includes a circuit (PC) board with interdigitated capacitance for balancing out inherent capacitance found within IDCs of the panel. Unwanted cross-talk signals are reduced as a consequence.

A connector jack having a body with a receptacle to receive a plug, a circuit board, and contact tines extending within the receptacle. Each tine has an end attached to the circuit board and a free end, and is moved in response to contact by a corresponding one of the plug contacts in a first direction as the plug is inserted into the receptacle. The jack includes resilient spring members extending within the receptacle, each positioned adjacent to a corresponding one of the tines to be engaged thereby when moved in the direction by the corresponding plug contact as the plug is inserted into the receptacle, and apply a supplemental force to increase contact force and tine resiliency. A tine contact portion has a pair of lateral members that receive a spring engagement portion therebetween and has a recess in which the spring engagement portion is positioned.

A compensating jack connector includes a printed circuit (PC) board with wire trace layers for reducing unwanted crosstalk originating in wire pairs including those found within a conventional communication plug coupled to the compensating jack connector. Some embodiments of the PC board of the compensating jack connector include layers having inter-digitated capacitance to form compensative capacitive coupling and multi-point compensative coupling and inductance to form inductive coupling to reduce the unwanted crosstalk. Pairs of wire traces are so oriented in some of the PC board layers to couple inductance between one pair of wire traces with inductance between another pair of wire traces to contribute in reduction of unwanted crosstalk. Some embodiments of multi-point compensative coupling position inter-digitated capacitance at different time delay distances from origination points of unwanted crosstalk and having different polarities to contribute in reduction of unwanted crosstalk. Other embodiments of the PC board have layers that include other capacitive coupling having a single time delay distance from a source of unwanted crosstalk. Further embodiments of the PC board of the compensating jack connector include layers having combinations of the inductive compensative coupling, multi-point compensative coupling, and the other capacitive coupling.

Communication connector with inductive compensation

A modular higher density communications coupling system including a universal platform for supporting multiple connectors from a single outlet hole is disclosed. The platform includes a main body member having a registration ridge extending forward of the main body member for extending into a standard sized outlet hole. A pair of apertures adjacent to each other extend through the main body member and are generally surrounded by the registration ridge. A pair of connector housings are attachable to the rear of the platform in alignment with the apertures for housing connectors. A pair of retaining members on two sides of the apertures hold the connector housings in position. A pair of support members extend rearwardly from the main body of the platform on the other two sides of the apertures. A termination plate is mounted in the support members, the termination plate having a plurality of electrical couplings for connecting the wire from a wall to the connector. A grounding screw mount provides easy access from the front, side or rear. The relationship between the retaining members, apertures, and support members facilitates a higher density of electrical couplings than previously possible in the prior art. Telecommunications apparatus of the type identified within the specification, in combination with the aforesaid, is contemplated as coming within the scope of the present invention.
