ABSTRACT:
A heat dissipating connector assembly is provided for use in retrofit applications to replace the electrical connector within the housing of an existing light fixture. In one embodiment thereof, the connector assembly includes a hollow, externally finned cooling body having a graphite foil-lined socket opening formed through a forward end portion thereof. The socket opening communicates with an enlarged cavity within a rear portion of the body which captively retains a connector formed from two stacked metal block pairs encapsulated within and separated by silicon insulating material. Pin openings are formed through the block pairs along the junctures between their individual blocks. Entry of the pins into the block openings slightly separates the blocks in each pair thereof, against the resilient force of the insulation material, to create an automatic "pin-wiping" action. In an alternate embodiment of the connector assembly, the finned cooling body is formed from two extruded metal sections which are encapsulated within and separated by silicon insulating material. Portions of these two sections integrally define the connector portion of the improved assembly.
