  • Patent number: 5226835
    Abstract: A plug for interconnecting a pair of wires at its input with a pair of insulation displacement connectors (IDC) at its output is improved. The plug comprises a dielectric housing and a pair of non-insulated conductors within the housing that cross over and are spaced-apart from each other. Each conductor comprises a generally flat blade portion for insertion into an IDC at one end, and a terminal for making electrical contact with a wire at the other. In the illustrative embodiment of the invention, the terminal comprises an insulation displacement connector. Additionally, the conductors are identical to each other, but are reverse-mounted with respect to each other to achieve crossover.

  • Patent number: 5186647
    Abstract: An electrical connector for conducting high frequency signals includes a number of input and output terminals that are interconnected by a pair of metallic lead frames that are mounted on a dielectric spring block. The lead frames are identical to each other and comprise several flat elongated conductors, each conductor terminating in a spring contact at one end and an insulation-displacing connector at the other. The lead frames are mounted on top of each other and their conductors are all generally parallel and close to each other. Only three of the conductors of each lead frame are arranged to overlap each other; and this occurs in a designated crossover region without electrical contact being made because of a reentrant bend in the conductors in the crossover region. As a result, crosstalk between specific conductors can be reduced by judiciously choosing the location of the crossover and the particular crossover pattern.

  • Patent number: 4865564
    Abstract: An easily assembled connecting block provides interconnection between modular plugs and insulated telephone wires or the like. The connecting block includes: (i) a metallic lead frame comprising a number of flat elongated conductive elements that terminate in closely spaced flat wires at one end thereof, each conductive element terminating in two pairs of insulation-displacing contact fingers at the other end; and (ii) a dielectric block for receiving the closely spaced wires within a jack housing contained therein and for supporting the metallic lead frame. In one embodiment the connectors are an integral part of the lead frame itself and are "sandwiched" between a pair of dielectric blocks, each block having a plurality of corresponding slots for guiding wires into the region between opposing contact fingers of the connectors.

  • Patent number: 4820192
    Abstract: An easily assembled connecting block provides interconnection between modular plugs and insulated telephone wires or the like. The connecting block includes: (i) a metallic lead frame comprising a number of flat elongated conductive elements that terminate in closely spaced flat wires at one end thereof, (ii) an equal number of metallic connectors that electrically couple to the conductive elements of the lead frame and further provide at least two pairs of opposing contact fingers for insulation displacement; and (iii) a dielectric block for receiving the closely spaced wires within a jack housing contained therein and for supporting the metallic lead frame. In one embodiment the connectors are an integral part of the lead frame itself and are "sandwiched" between a pair of dielectric blocks, each block having a plurality of corresponding slots for guiding wires into the region between opposing contact fingers of the connectors.

  • Patent number: 4650269
    Abstract: A modular plug connector is adapted to terminate a cord having a number of insulated solid wire conductors. The connector includes a dielectric housing that facilitates interconnection between the solid wire conductor and a metallic terminal which slides into a terminal-receiving slot of the dielectric housing. The metallic terminal includes three tangs, or blades, that pierce the insulation surrounding the solid wire and achieve electrical contact. Adjacent tangs grasp the solid wire on opposite sides of its center line, but are controllably spread before making contact with the wire by cam surfaces molded into the side walls of the terminal-receiving slot. Reliable connections are therefore made between a metallic terminal and a solid wire conductor without severing it.
