Abstract

A socket for operatively holding a wedge-base lamp has terminal guards positioned within a lamp receptacle to protect electrical terminals inside the receptacle from damaging contact by a lamp as it is inserted into the receptacle. The guards comprise a pair of terminal covers located between the terminals and the open end of the receptacle, the covers defining a gap which receives a base portion of the lamp and guides it into a proper position with respect to the terminals. The lamp base has a pair of lead wires which make contact with the terminals, and guide notches formed in the gap-defining edges of the guards engage the wires and draw them into contact with the terminals as the lamp base passes through the gap.
