    Abstract: A ground fitting allows simplified electrical connection between a ground wire carried in a metal sheathing, and a ground point such as a water pipe or ground rod. The metal sheathing is cut and separated and a short length of ground wire is exposed. The ground wire is inserted laterally into a wire clamp portion of the ground fitting, and opposing ends of the metal sheathing carrying the ground wire are inserted longitudinally under clamping plates on opposite sides of the ground fitting. A ground screw is tightened against the ground wire to hold the ground wire in the ground fitting and plate screws securing the clamping plates are tightened to secure the sheathing between the clamping plates and clamp seats. Ridges may be provided on one or both of the clamping plates and the clamp seat to engage a spiral exterior surface of the metal sheathing.

    Abstract: Embodiments may include connectors with discharge elements integrated into the connectors to interconnect conductors of a cable to attenuate or discharge an electrostatic charge built up on the conductors. In some embodiments, the conductors are momentarily connected to ground as the connector couples with another connector to interconnect a cable with, e.g., a computer. In further embodiments, the discharge elements interconnect the conductors of a cable to redistribute an electrostatic charge and thereby minimize the impact of a discharge when the cable couples with an electronic system such as a computer. Another embodiment comprises a male connector with discharge elements, which ground conductors of the cable as the cable is being inserted into the connector. The discharge elements are pushed out of the way of the conductors as the conductors couple with the connector.

  • Patent number: 7581966
    Abstract: An electric wire is crimped by electric-wire crimping claws of a ground terminal. The electric wire is thermocompression-bonded to a thermocompression bonding surface of the ground terminal. The ground terminal is fixed to a vehicle body panel by a fastening force of a bolt and a nut and by an engaging force of a vehicle body fixing claw. The ground terminal is adapted so that each of the crimping force and a thermocompression bonding force is weaker than a fixing force. Consequently, in a case where the electric wire is peeled off in a direction perpendicular to the thermocompression bonding surface, the electric wire can easily be detached from the vehicle body panel without removing the bolt and the nut. Also, a vehicle body mounting hole is placed in the vicinity of the electric wire crimping claws and the thermocompression bonding surface, so that the moment of the ground terminal is reduced.

  • Patent number: 7491071
    Abstract: An end portion of a shielding layer is inserted between an inner tubular portion and an outer tubular portion of a shield ring by the use of a tubular pushing jig, and in this condition when a shield shell is inserted into the shield ring in a direction opposite to the direction of inserting of the shielding layer, the shield ring is pressed by the shield shell, so that a gap between the inner tubular portion and the outer tubular portion decreases, and the shielding layer is firmly held between the inner and outer tubular portions, thereby achieving a fixed condition of the shielding layer. Namely, the shield ring and the shield shell are fixed to the end portion of the shielding layer.

  • Patent number: 7459643
    Abstract: A dual-clamp device attaches a pair of metal clad cables to a junction box. The clamp device is integrally formed defining a pair of side-by-side cable receiving members separated by a central web. Each cable receiving member is generally in the form of an elongate split cylinder permitting radial resilient movement. Forward fingers on each cable insertion end of the cable receiving member provides for engagement with the wall in the junction box upon insertion. The cable receiving member supports the wall of the junction box between the forward fingers and a spring tab on the central web.

  • Patent number: 7456356
    Abstract: A grounding clip is a shelf-grounding device includes a resilient conductive clip that installs onto a fully assembled shelving unit, providing a plurality of electrical connections between the shelf and post to reduce the risks from electrostatic discharge, or ESD. The clip can be installed and removed without the use of tools and is held securely in place when attached. Since the clip is attached after the shelving unit is assembled, less skill is required by the installer during the installation or reconfiguration process. The clip is reusable and provides electrical connectivity between the shelf and post regardless of whether the shelving unit was assembled with conductive or plastic split sleeves.

    Abstract: A connector module is coupled to a ground terminal to discharge accumulated charges. The connector module includes a connector and a metallic housing. The connector has a connecting port. The metallic housing is covered over the connector. The metallic housing has a contact surface as the ground terminal and a flexible portion protruding from the contact surface contacts the ground terminal to discharge the accumulated charges to decrease the electromagnetic interference (EMI) problems, and malfunctions of electronic system caused by electrostatic discharge (ESD) are also decreased. The stability and the reliability of the connector module are thus ensured.
