Filed:

Nov 18, 2008

Appl. No.:

12/273524

Inventors:

Andrew Adams Litteer - Clay NY, US

Assignee:

Cooper Technologies Company - Houston TX

International Classification:

H01R 13/644

US Classification:

439139

Abstract:

Receptacles configured to securely mate with hazardous area plugs are provided. The receptacles include a housing, a locking plate, and a sliding lockout key. The sliding lockout key prevents the locking plate from rotating when the receptacle and plug are disconnected or when a standard plug is inserted into the receptacle. When the proper plug is inserted into the receptacle, the sliding key portion is depressed and allows rotation of the locking plate. Upon rotation, pins from the plug contact internal pins of the receptacle and make an electrical connection.

Abstract:

Lighting assemblies or lighting fixtures suitable for use in a hazardous location are provided. Generally, the lighting fixtures include a light source assembly, a heat sink, a driver housing or gear module, and a conductive sealing member between the light source assembly and the heat sink. The conductive sealing member has a thermal conductivity of at least about 6 Watts per meter-Kelvin, and/or a thermal impedance of less than about 0. 21 degree-C. inch squared per Watt. The lighting fixtures have controlled directional heat transfer from the light source assembly to the exterior of the lighting fixture, while minimizing the heat transferred to the driver housing.
