  • Patent number: 4227760
    Abstract: A lamp socket adapted to receive a bayonet base lamp bulb for illumination uses on an automotive vehicle. The socket is essentially cup-shaped and of one-piece plastic construction. The bulb contacting terminal members and grounding ring are all adapted to be inserted from the bulb end of the socket. The terminal members snap into designated slots in the bulb receiving wall of the socket. The grounding ring is a unitary, formed member with terminals at both opposed ends. The grounding ring forms the wall into which the bulb base is inserted. With the terminal members and grounding ring in place, terminals are provided for the engagement with conductors of a printed circuit board. The terminals have spring contactors spaced in an annulus insulated and spaced from the bulb. The bulb imposes a locking pressure on the bulb terminals by pushing the terminals further into the assembly.
