摘要:
There is provided an electrical connector, including a housing which receives a plurality of elongated contacts for receiving electrical signals. Each contact includes a free end. Each contact having a major bend therein. At least a portion of adjacent contacts between their respective free ends and major bends are not parallel so that electrical signal transmission of the connector is enhanced.

There is provided an apparatus for reducing pair to pair cross talk which arises in electrical connectors due to closely spaced elongated parallel contacts while maintaining proper longitudinal balance and characteristic impedance of each pair. The cross talk which occurs within the connector is reduced by modifying certain circuit paths either inside or outside of the connector so that each conductor of a first pair which is parallel to and cross talking with an adjacent conductor of a second pair in the connector is relocated adjacent and parallel to the other conductor of the second pair over a predetermined distance. A substantial amount of incident reflected signal, due to impedance mismatch, is reduced by the addition of an additional circuit path, which carries the same signal as one of the relocated conductors of the first pair, at a position adjacent to the other conductor. It is preferred that the relocation of the circuit paths and the additional circuit path occur on a circuit board which is attached to the connector.

A telecommunications connectivity system including a patch panel comprising a plurality of ports, each port including first and second electrical terminals, the first electrical terminal enabling at least one data communications standard not enabled by the second electrical terminal. The telecommunications connectivity system also includes a terminal selection system including a terminal selector that houses an electrical connector. The terminal selector may be installed in one of the ports such that the electrical connector connects to either the first or second electrical terminal, as preselected. The telecommunications connectivity system also includes a wall receptacle system electrically connected to each of the ports, the wall receptacle system including first and second jacks, the first jack enabling at least one data communications standard not enabled by the second jack.

A wireless distribution secured cabling system includes faceplates, each of which contains an antenna or other radiating element and an active amplifier, which serves as a bi-directional repeater for the wireless communication system. The system further includes a patch panel or distribution module which connects multiple cables, which may be either twisted pair or coaxial, to amplifier, acting as a power divider and/or an impedance matching device. An antenna, which may be mounted either outside of a building structure or inside the building structure, provides communications between the structured cabling system and a service provider base station.

A keyed modular connection system including a nonstandard wiring configuration, a plug wired in the preselected nonstandard wiring configuration and including exterior surfaces that define plug recesses, a jack wired in the preselected nonstandard wiring configuration and including interior surface that define jack recesses, plug protrusions extending from the external surfaces of the plug and configured to be received by the jack recesses when the plug is inserted into the jack, jack protrusions extending from the internal surfaces of the jack and configured to be received by the plug recesses when the plug is inserted into the jack, and when a plug not wired in the preselected nonstandard wiring configuration is attempted to be inserted into the jack, the jack protrusions prevent the attempted insertion, and when the plug is attempted to be inserted into a jack not wired in the preselected nonstandard wiring configuration, the plug protrusions prevent the attempted insertion.
摘要:
Patch cords suitable for Category 6 data transmission applications terminated at the two ends by first and second modular plugs that differ from each other in a complementary manner such that relative positioning of wire pairs is maintained at both ends of the patch cord, and without any crossing of any wire of one pair over a wire of another pair within either modular plug. Within each plug, wire-receiving passages receive the ends of the cable wires. Within one of the modular plugs, the wire-receiving passages corresponding to position numbers 3 and 6 (Pair P3) are offset from the remaining wire-receiving passages in a direction relatively farther from the terminal side of the plug. Within the other of the modular plugs, the wire-receiving passages corresponding to position numbers 3 and 6 (Pair P3) are offset from the remaining wire-receiving passages in a direction relatively closer to the terminal side of the plug. The offsets allow the conductors of each of the Pairs P1, P2, P3 and P4 to remain paired as much as possible to maintain characteristic impedance so as to improve return loss characteristics. In addition, the wires are separated as pairs from other pairs as much as possible to reduce crosstalk couplings.
摘要:
A multi-media cross-connect facility which employs an industry-standard "Type 89" bracket as a mounting base. A support for a set of connection devices, such as snap-in modular jacks, fiber optic cable coupler adapters and coaxial cable coupler adapters, takes the form of an elongated rectangular panel. The panel is formed of sheet metal having a thickness of 1/16 inch, with the edges rolled to define hems resulting in 1/8 inch thick mounting regions along the sides. The 1/16 inch thick intermediate region has apertures for receiving snap-in connection devices, while the 1/8 inch thick mounting regions, which are also provided with notches, are properly received by the "Type 89" bracket.
