  • Patent number: 7674122
    Abstract: This invention relates to providing a means to removeably mount a feed through/grounding bushing commonly used to bond together, ground and/or park power distribution cables. Many pieces of power distribution equipment have U brackets for removable attachment of accessories and temporary placed maintenance equipment. The present invention addresses holding the bushing at an angle relative to the U bracket and surrounding surface and adjustability of the bushing height relative to the U bracket for strain relief and adjusting for improved work room. Also addressed is the advantage of cable identification by numbering the wells so that a lineman may readily select the cables even after the bushing may have been set aside for equipment replacement. This is especially useful on but not limited to this invention since the U bracket mounting means is moveable and would not always provide positive identification of one end of a multi well bushing.

    Abstract: A high-voltage connector is described, having a plug (10) with a rubber cone (131; 132, 133) for insertion in a socket (20). A connector of this kind is also referred to as a rubber-cone plug system and is used in particular for connecting X-ray generators to high voltage generators. The connector is characterized in particular by the facts that the rubber cone has a first portion (131) having a first angle of application (A) in a tight-fitting joint (14) and at least one second portion (132, 133) having a second angle of application (B) in the tight-fitting joint, and that respective female contacts (16, 17), into which contact pins (23, 24) for making contact with the high voltages extend, are incorporated in each second cone portion (132, 133). The first angle of application (A) is preferably greater than the second angle of application (B) in this case, thus causing good insulation against high voltages to be ensured by a high applied pressure from the plug.

  • Patent number: 7431601
    Abstract: An automatic power line disconnect apparatus has a sensor pin for signaling the separation of the plug from the disconnect apparatus. The operative movement of the sensor pin is shorter than the length of the male electrical connectors on the apparatus, thereby insuring that the apparatus is disconnected from the power line before the electrical connectors' contact is broken to reduce electrical connector erosion from arcing. A motor driving a rack and pinion gear combination responds to an engine starter signal by driving the rack in a direction that disconnects the power line plug from the automatic disconnect apparatus. Further circuits are provided to lock out low voltage starter signals, photoelectric detectors to control movement of the rack, and timer circuits to limit the duration of the motor operation and to lock out starter signals when the disconnect apparatus is being separated from the power line plug.

  • Patent number: 7431599
    Abstract: The present invention relates to a cable termination system for connection of a cylindrical member, such as a cable, within a housing containing multiple bores. One or more bores of the housing are held in a radially expanded state by one or more retaining devices. The cable may be coupled to a coupling device, such as a metallic lug, and inserted into a first bore such that a connection is made with a first mating device inserted into a second bore. Additionally, a second mating device may be inserted into a third bore to finalize the connection. After the connection is completed, each retaining device is de-coupled from its respective bore causing the housing surrounding the bore to contract to its original state, thereby forming a tight seal between the housing and the cable or mating device.

  • Publication number: 20080242134
    Abstract: A high-voltage connector is described, having a plug (10) with a rubber cone (131; 132, 133) for insertion in a socket (20). A connector of this kind is also referred to as a rubber-cone plug system and is used in particular for connecting X-ray generators to highvoltage generators. The connector is characterized in particular by the facts that the rubber cone has a first portion (131) having a first angle of application (A) in a tight-fitting joint (14) and at least one second portion (132, 133) having a second angle of application (B) in the tight-fitting joint, and that respective female contacts (16, 17), into which contact pins (23, 24) for making contact with the high voltages extend, are incorporated in each second cone portion (132, 133). The first angle of application (A) is preferably greater than the second angle of application (B) in this case, thus causing good insulation against high voltages to be ensured by a high applied pressure from the plug.

  • Patent number: 7427207
    Abstract: This invention relates to providing a means to removeably mount a feed through/grounding bushing commonly used to bond together, ground and/or park power distribution cables. Many pieces of power distribution equipment have U brackets for removable attachment of accessories and temporary placed maintenance equipment. The present invention addresses holding the bushing at an angle relative to the U bracket and surrounding surface and adjustability of the bushing height relative to the U bracket for strain relief and adjusting for improved work room. Also addressed is the advantage of cable identification by numbering the wells so that a lineman may readily select the cables even after the bushing may have been set aside for equipment replacement. This is especially useful on but not limited to this invention since the U bracket mounting means is moveable and would not always provide positive identification of one end of a multi well bushing.

  • Patent number: 7422455
    Abstract: A port (such as, but not limited to, an RJ45 port) may comprise a cavity having a plurality of pins and an electrostatic discharge element coupled to a system ground. As the plug is inserted into the cavity, the electrostatic discharge element contacts the plug prior to the plug coming into electrical contact with the port pins and provides a discharge path to the system ground during a cable discharge event. Once the plug is fully inserted within the port, the electrostatic discharge element does not electrically contact the plug or the port pins and therefore has substantially no affect on the normal connection between the port and the plug.

  • Patent number: 7407400
    Abstract: Methods and arrangements to methods and arrangements to attenuate electrostatic discharges of a cable are disclosed. 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: 7404724
    Abstract: ESD damage caused by connecting devices that have separate grounds, is reduced by equalizing the charge on the first and second device grounds before connecting their signal lines together; but when the grounds are equalized, the transfer of charge between them is sufficiently slowed down so as to avoid harming components within the device receiving the extra charge. In one embodiment, a connector for connection with a complementary connector is provided with an inhibited shell. The inhibited shell is mounted to the connector body for connection with a shell on a complementary connector. The inhibited shell is configured (e.g., with a conductive polymer having a desired resistance) to sufficiently slow down the detrimental transfer of charge between the separate grounds on the connected devices while at the same time allowing them to equalize with one another.
