International Classification:

H05K 7/20

US Classification:

361699, 361689, 174 151, 165 804, 16510433

Abstract:

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

Assignee:

Hamilton Sundstrand Corporation - Windsor Locks CT

International Classification:

H01R 13/24

US Classification:

439700, 439246

Abstract:

An electrical connection includes a socket having a bore and a pin. The pin is allowed to move along an axis defined inwardly into the socket bore, and also to move radially relative to the axis. The socket bore has a generally conical portion. The pin has a generally conical face. The generally conical face of the pin is in contact with the generally conical portion of the socket. A motor system including such a connection is also disclosed. In another feature, an electrical connection includes a socket having a bore and a pin. The pin is allowed to move along an axis defined inwardly into the bore, and also to move radially relative to the axis. The pin is spring-biased into the bore such that an end of the pin seats on an end face of the bore.

International Classification:

G01L 1/00

US Classification:

73783, 73855, 3406861, 340687

Abstract:

A sensor assembly for sensing relative movement between adjacent panels includes a base and first and second arms pivotally mounted to the base. An electrical connecting element is attached to the first and second arms and holds the first and second arms in a first position to indicate a first condition. When the first and second arms have moved relative to each other by a predetermined amount, the electrical connecting element breaks to indicate a second condition.

International Classification:

B64D 41/00

US Classification:

244 58

Abstract:

An electric power generation and distribution system includes a primary distribution panel, which preferably operates at 230 VAC, and a High Voltage Direct Current (HVDC) panel in direct electrical communication therewith. The HVDC panels power motor controllers which drive electric motors residing in the center or aft sections of the aircraft. As many of the large electrical loads are located in the aft section of the aircraft, an aft electronics bay is located adjacent the aircraft wing roots to house the primary distribution panels and the HVDC panels.

International Classification:

H02H 3/08

US Classification:

361 931

Abstract:

A solid state power control module contains non-volatile memory. A switch for opening is provided to break a supply of power to a component. The switch is operable to trip (open) when an undesirable condition is detected, and further to be opened upon receiving a control signal. A status of the switch is stored in the non-volatile memory. A detector is provided for identifying when a module has been mounted in a housing, and communicates with the non-volatile memory if it is determined that the module is newly installed in a housing. A system and method are also claimed.

Appl. No.:

11/274996

Inventors:

Francis Belisle - Roscoe IL, US

Assignee:

Hamilton Sundstrand Corporation - Rockford IL

International Classification:

H01R 9/00

US Classification:

361823, 361824

Abstract:

An electrical distribution system provides a Line Replaceable Modules (LRM) with a printed wire board (PWB) which is of a relatively thick construction. The PWB is manufactured of a relatively thick construction to provide structural support for a multitude of electrical components as well as a board mounted contactor. Each contactor is mounted directly to the PWB. As the primary contactor switch function is board mounted, support functions such as coil drivers, economizing switches, auxiliary switches become PWB mounted components that are assembled to the PWB for communication through the board circuit traces rather than the heretofore required wiring harnesses.

US Classification:

361 931, 361 935, 361748, 361752

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.
