Abstract: The present invention provides a plug-in wire terminal system for a lamp socket. The system includes a bushing mounted in a passage through the base wall of the socket and a terminal gripping the lead of a connecting conductor that is adapted to plug into the hollow core of the bushing. The terminal is permanently mounted in the bushing by way of an outwardly biased cone portion that includes a plurality of biasable side strips that snap out once the cone passes an internal shoulder in the core of the bushing. The terminal has a biased contact portion that electrically connects the terminal with the bushing. The bushing includes a flared inner rim that both holds the bushing in place and electrically connects the bushing to a bottom flange extension of the screw shell mounted in the socket.
