  • Patent number: 9728897
    Abstract: A power connector assembly includes a connector housing and a plurality of receptacles defined in the connector housing. Each of the receptacles defines a keyed interface profile such that each interface profile is adapted to individually couple to a respective feeder connector. Each one of the receptacles has an interface profile different from the other interface profiles. The plurality of receptacles can include a first profiled interface, a second profiled interface and a third profiled interface. Each of the first, second and third profiled interfaces can define a longitudinal connector axis. The number of profile interfaces can be increased by selection of other angle positioned within the housing which prevent incorrect receptacles from be installed (i.e. connected).

  • Patent number: 9431766
    Abstract: A keyed power connection system is disclosed. The keyed power connection system may have connectors and terminal studs. Each connector may have a captive fastener and may have a connector keying portion comprising a keyed aperture forming an opening in and defined by a connector body of the connector and having a keyed connector diameter. The connector may receive and be selectably connected to a terminal stud having a keyed stud diameter. The keyed stud diameter and the keyed connector diameter may correspond to ameliorate the risk of connecting a connector to a mismatched terminal stud. The captive fastener may engage the terminal stud to retain the connector in position relative to the terminal stud.

  • Patent number: 8559149
    Abstract: An aircraft power distribution system is disclosed that includes a power distribution box. A generator supplies power to the power distribution box, and a load receives power from the power distribution box. The power distribution box includes a board supporting plug-in pins receiving the power. A contactor is supported by the board to selectively providing power to a secondary power distribution connector supported on the board. The board includes power traces that are run within the board to connect the plug-in pins to the secondary power distribution connector. Protection and secondary power distribution circuitry is also supported by the board and connected to the contactors and/or power traces by control traces. The power and control traces eliminate loose wiring and harnesses.

  • Patent number: 7692924
    Abstract: The present invention provides a rack suitable for housing a liquid-cooled electric unit. A rack 2 comprises an electric connector 12 for supplying electricity to the housed electric unit 50, and a fluid connector 14 for supplying cooling liquid to the housed electric unit 50. The fluid connector 14 and the electric connector 12 are arranged at different positions in a horizontal cross section (plane) of the rack 2. More preferably, the electric connector 12 is mounted on a back panel 6 of the rack 2, while the fluid connector 14 is mounted on the foreside of the rack 2. Such a configuration makes it less likely that the cooling liquid leaking from the fluid connector 14 drips onto the electric connector 12.

  • Patent number: 7538990
    Abstract: An apparatus, and a method of opening and closing electrical power feed lines using a hybrid contactor, which combines a traditional set of mechanical main contacts with a high voltage solid state switch. The solid state switch provides a parallel current path around the main contacts. When the main contacts are to be opened or closed, the solid state switch is first closed, diverting current away from the main contacts to prevent arc formation when the main contacts are being opened or closed. Once the main contacts are opened or closed, the solid state switch is opened, as the parallel current path is no longer needed. Optional auxiliary contacts are connected in series with the solid state switch to provide galvanic isolation between an input terminal and an output terminal.
