ABSTRACT:
A lamp base having a floating rivet pin is described. Due to mechanical stress, sealed beam reflector leads may need mechanical strengthening; however, heat stress may be transmitted through the strengthening means. A rivet pin may be coupled in the lamp base having one face abutting the base, a shaft portion closely, but slideably positioned in a passage and a second face offset from the base. During thermal expansion of the lead, the second pin face may approach abutment with the base without stressing the seal structures. The floating rivet pin, secured by being snugly fit radially in the base passage to hold the floating pin, then resists the twisting that may occur during mounting.
