  • Publication number: 20030073328
    Abstract: An interconnection system includes spacers arranged adjacent each other in a row, the spacers having cable sections disposed therein. Each cable section has at least one center conductor and an outer conductive shield. All of the cable sections have one end exposed on a first plane and a second end exposed on a second plane. Electrically conductive contacts are disposed within apertures in a pair of interposers so as to have one end making electrical contact with one of the cable sections and another end extending through its respective aperture in its respective interposer.

  • Publication number: 20020146941
    Abstract: A socket connector for a pin connector including a module body with a plurality of slots is described. A plurality of wafers are installable in a corresponding plurality of slots in the module body and each wafer has multiple offset tuning forks. The module body has a coring wall with multiple wedge shaped protrusions for each of the offset tuning forks of the wafer.

  • Publication number: 20020094705
    Abstract: The present invention is directed to a high density electrical connector which can provide 80 or more twinax connections per linear inch in a 20 millimeter card slot. In a typical electronic system package, 20 millimeters is the spacing from center line to center line of the adjacent parallel daughtercards. Twinax cable is coaxial cable that contains two inner conducting wires rather than one. The two inner conducting wires provide two physical channels. Coaxial cable is called “coaxial” because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as ground.

  • Patent number: 6354885
    Abstract: The present invention is used in conjunction with two piece connector systems. The present invention provides an integral keying and an electrostatic discharge path. The daughtercard connector has at least two electrostatic discharge paths into an electrostatic discharge contact which then provides a path to a guide pin of the backpanel housing.

  • Patent number: 6267625
    Abstract: The present invention provides an electrical interconnect system using multiple grounding methods to reduce or prevent spurious signals from interfering with high density contacts carrying high speed transmissions. A first connector includes an insulative pillar partially surrounded by a plurality of signal contacts. A central ground contact is at least partially located within the insulative pillar. A second connector includes a plurality of flexible signal contacts for mating with the signal contacts adjacent the insulative pillar. Additionally, flexible ground contacts in the first connector are in contact with an electrically conductive shield. The second connector also includes a central ground contact for receiving the central ground contact of the first connector. The ground contacts provide a first method of providing a ground path to reduce spurious signals from entering the signal path.

  • Patent number: 6206729
    Abstract: Disclosed is an electrical interconnect system using multiple grounding methods to reduce or prevent spurious signals from interfering with high density contacts carrying high speed transmissions. A first connector includes an insulative pillar partially surrounded by a plurality of signal contacts. A ground contact is at least partially located within the insulative pillar. A second connector includes a corresponding plurality of flexible signal contacts for mating with the signal contacts adjacent the insulative pillar. The second connector also includes a ground contact for receiving the ground contact of the first connector. The ground contacts provide a first method of providing a ground path to reduce spurious signals from entering the signal path. An electrically conducting shield is located outside the signal contacts when the first and the second connectors are mated. The first connector includes a member which provides a ground path between the first connector and the electrically conducting shield.

  • Patent number: 5997361
    Abstract: An electrical cable connector is disclosed for connecting a plurality of electrical conductors to a printed circuit board. The cable connector includes a cable socket connector having a plurality of female insulation displacement contacts which can be mated with male signal-carrying pins contained in a pin shroud on a printed circuit board. The cable socket connector is comprised of a hood which retains two or more wafers. Each wafer contains a plurality of insulation displacement contacts. The cable socket connector may include a latch for securing the cable socket connector to the pin shroud and shielding to prevent extraneous signals from being transmitted into the circuits on the printed circuit board through the cable connector. The cable connector also includes an arrangement for keying the cable socket connector to the pin shroud to control the location of insertion of the cable socket connector into the pin shroud.

  • Patent number: 5152700
    Abstract: A printed circuit board connector includes a daughterboard connector and a pin header. The daughterboard and pin header contacts are secured in their respective housings by interference nibs which are mounted on resilient portions of the contacts. Various constructions are disclosed for separating contact from a carry strip by means of a weakened break-line which will secure the contact to the carry strip during post-manufacturing operations and will form a sharp V-shaped tip when the contact is intentionally removed from the carry strip.
