Abstract:
Embodiments of the present invention relate to the field of telecommunication, and more specifically, to communication connectors such as, for example, shielded plug and jack connectors. In an embodiment, the present invention is a communication jack that includes a housing and a front sled assembly having a plurality of plug interface contacts (PICs), the front sled assembly being moveable along a horizontal plane of the communication jack between a first position and a second position, the first position being different from the second position.
Abstract:
A communications cable has coated conductor wires separated by a wire separator to form a twisted pair configured to maintain a distance of approximately 0.45 mm between the conductors and a characteristic impedance of approximately 100 ohms. The coating on the conductors may be an enamel or other appropriately thin insulating material.
Abstract:
A Rj45 plug (34) comprising: a housing (42,50) with an opening; a sled assembly (60,100,152,180) contained within the housing wherein the sled assembly (10,100,152,180) has a plurality of contacts (68,158,184) accessible via the opening; and a plug interface contact (PIC) cover (62,112,158,182) at least partially surrounding a first contact of the plurality of contacts wherein the PIC cover (62,112,158,182) is electrically insulated from the first plug interface contact of the plurality of contacts and electrically connected to a second plug interface contact of the plurality of contacts.
Abstract:
A communications cable (22) having a plurality of twisted pairs (26) of conductors and various embodiments of a metal foil tape (34) between the twisted pairs (26) and a cable jacket (33) is disclosed. The metal foil tapes (34) include a cut (37) that creates discontinuous regions (38) in a metal layer (35) of the metal foil tapes (34). When the metal foil tapes (34) are wrapped around the cable core (23), the discontinuous regions (38) overlap to form at least one overlapping region. The cuts (37) are formed such that overlapping region is small and limits current flow through the metal foil tapes (34), thereby minimizing alien crosstalk in the communications cable (22).
Abstract:
A communication connector has a housing for receiving a communication plug, a printed circuit within the housing, a switch which actuates the printed circuit board, and a translating crossbar which engages the switch. The printed circuit board is moved dependent upon a type of plug inserted. The movement of the circuit board can help to selectively engage one of two sets of circuit traces and groupings of contacts.
Abstract:
The present invention provides a communication jack for connecting to one of a first plug and a second plug. The jack includes a housing, plug interface contacts, and coupling circuitry. The plug interface contacts are at least partially within said housing and include a plurality of contact pairs having at least a first contact pair and a second contact pair. The coupling circuitry is configured for engaging said first contact pair and said second contact pair when said first plug is inserted into said housing. The coupling circuitry is configured for disengaging from said first contact pair and said second contact pair when said second plug is inserted into said housing.

Abstract:
A method of detecting a fault in a power distribution system is provided. The method comprises: providing a power source; providing a load to be powered by the power source; providing a connection from the power source to the load; placing a current source on the connection from the power source to the load; detecting a change in a voltage on the connection indicative of a change of an impedance in the power distribution system; and determining a fault is present within the power distribution system based on the detected change in the voltage on the connection.
