Patent number: 7674122Abstract: 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.Type: GrantFiled: August 13, 2008Date of Patent: March 9, 2010Inventor: Denton L.

Publication number: 20080242134Abstract: 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.Type: ApplicationFiled: April 15, 2005Publication date: October 2, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventor: Bernd Wandler

Patent number: 7427207Abstract: 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.Type: GrantFiled: July 27, 2006Date of Patent: September 23, 2008Inventor: Denton L. Jackson, III

Publication number: 20080220638Abstract: A loadbreak connector system and methods for visible break include first and second mating connector assemblies configured to make or break an electrical connection under energized circuit conditions, the first and second mating connectors selectively postionable relative to one another. One of the first and second mating connectors includes an arc follower, and the other of the first and second mating connectors includes an arc interrupter. The arc interrupter is configured to receive the arc follower, and the first and second meting connectors are positionable in an disconnected position wherein the arc follower remains engaged to and is located within the arc interrupter. Arc energy is distributed among multiple locations to reduce arc intensity.Type: ApplicationFiled: May 23, 2008Publication date: September 11, 2008Inventors: David Charles Hughes, Brian Rodd Steinbrecher

Patent number: 7422455Abstract: 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.Type: GrantFiled: October 26, 2006Date of Patent: September 9, 2008Assignee: Intel CorporationInventor: Ori Eshet

Patent number: 7407400Abstract: 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.Type: GrantFiled: June 18, 2007Date of Patent: August 5, 2008Assignee: International Business Machines CorporationInventors: Mithkal M. Smadi, Anthony C. Spielberg

Patent number: 7404724Abstract: 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.Type: GrantFiled: April 2, 2004Date of Patent: July 29, 2008Inventor: Robert Dennis Miller
