Abstract:
A copper head socket for a light bulb comprising:(a) a base seat having an open end, another end of the base seat having a cylindrical shape center shaft hole, an inner bottom edge of the cylindrical shape center shaft hole being provided with a blocking edge, a wall surface of the cylindrical shape center shaft hole being formed into a plurality of deep and shallow slots by means of a plurality of protruded rails;(b) a connection seat which is a hollow cylinder having one end connected to the open end of the base seat and an inner bottom end of another end of the hollow cylinder being provided with an edge and a pair of protruded arch-shaped blocks;(c) a threaded base seat including two corresponding members having one end hingedly mounted together to grip a copper cap of the light bulb when the light bulb is inserted into the threaded base seat, another end of the threaded seat having a center aperture;(d) a press-stopping mechanism having a press rod, a rotating peg inserted into a top end of the press rod, and a spring mounted at a top section of the rotating peg, wherein the press rod is a hollow shaft body and a top end of the shaft body has eight positioning teeth which can slide within the shaft hole of the rotating peg, a middle section of the shaft body is provided with four stopping teeth and a bottom section of the shaft body is inserted at the top end of the press rod, and the spring is restricted in between a hole edge of the top end of the rotating peg and the shaft hole of the base seat such that the rotating peg and the press rod maintain an elastic pressure;(e) a hole cap which covers the shaft hole of the base seat and providing passage for wires of a power source;(f) a positive wire end of a power source passes the hole cap, the rotating peg, the press rod in sequence and is welded at an outlet at a bottom end of the press rod, and a negative wire end passes through the base seat and is welded at the threaded base seat to form a loop; andthereby a copper capped electrical light bulb can urge the socket so that loading and/or unloading of the light bulb can be achieved easily and conveniently.
