ABSTRACT:
A Christmas lamp socket is provided that includes a socket body and an inner cylindrical wall inserted into the socket body. The socket body has two opposing elongate vertically directed plates inside, an annular groove formed in an inner surface at an upper end thereof. The inner cylindrical wall is formed by two semi-cylindrical walls combined together, each wall having a vertical slot formed in an outer surface for receiving a respective one of the two vertical plates of the socket body therein. Each wall also has an annular ridge formed on an outer surface at the upper end thereof for engagement with the annular groove of the socket body to stably couple the cylindrical inner wall to the socket body. A threaded portion is formed on each inner wall to mate with a threaded metal portion of a lamp. A slot is formed between abutting vertical ends of the two semi-cylindrical inner walls for an elongate conductor to extend therein and protrude out of the slot to contact the metal screw base of a lamp.
