Abstract
Abstract An improved electrical contact member formed of an electrically conductive metal and adapted for mounting in a cavity in an insulated housing body, where said contact member is subjected to elevated temperatures sufficient to cause softening or relaxation of said metal. The improvement therein is achieved by the addition thereto of a U-shaped insert, fabricated from steel resistant to softening or relaxation at said elevated temperatures, at one end of said contact member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
165 words
An improved electrical contact member comprising a conductor connecting end constituted by a pair of interconnected parallel plates joined by a pair of transverse straps to define a wire receiving mouth conveying to a pair of aligned wire receiving slots and in respective plates, and a tab receiving end constituted by extensions of said parallel plates with the end most portions thereof split to define two legs and having a tab receiving slot, where each said leg is provided with means for engaging an insert, a U-shaped insert fabricated from a sheet of spring steel and located between said parallel plates in a position perpendicular to the planes of said parallel plates, and seated in said means, where one end of said insert engages corresponding legs of each said plate, and the opposite end of said insert engages the other legs of each said plate, whereby the split legs of each said plate define a common slot with said insert for receiving a tab therein.
Claim 2
Dependent Claim
