ABSTRACT:
A lamp socket (10) has first and second cylindrical body halves (12, 14) respectively. The first body (12) half has a first outer surface (16) and a first inner mating surface (18), the first inner mating surface (18) including a first depression (19). An insulating sheet (20) is positioned adjacent the inner mating surface (18). A plug (22) is fitted into the first depression (19) and includes a flange (24) that overlies the insulating sheet (20) and maintains the insulating sheet (20) in contact with the first inner mating surface (18). The second body half (14) has a second outer surface (26) and a second inner mating surface (28) and includes a second depression (30). The second body half (14) overlies the first body half (12) with the mating surfaces (18, 28) adjacent one another with the insulating sheet (20) held therebetween. The second depression (30) encompasses the flange (24). A dual function retainer (32) holds the various pieces together and comprises a tubular member (34) extending from the first body half outer surface (16) though the plug (22), the tubular member (34) being deformed at its inner terminus (36) to thereby maintain the plug (22) in position in the depression (19); and a threaded member (37) extends through the tubular member (34) and through an aperture (38) in the second body half (14). Means (40) on the threaded member (37) retain the first and second body halves (12, 14), together. In an alternate embodiment, the tubular member (34) is threaded, thus eliminating the need for a washer and nut.
