Claims

[Scope of utility model registration request]

On both sides of the outer periphery of one opening into which the lamp cap is inserted, there are hook-shaped notched grooves into which pins protruding from both sides of the lamp cap are guided and locked. A cylindrical metal socket body with a spring receiving part on the side edge and engaging holes on both sides of the outer periphery of the middle part, and a connection terminal for the lamp at the tip. The positive side and negative side lead wires that are attached to the socket body and pulled out from the other opening of the socket body, and the respective locking pieces protruding from both sides of the outer periphery to which the connection terminals are attached are engaged with each other. An insulator is movably housed in the socket body in a manner to engage with the hole, and an insulator is housed in the socket body in such a manner that one end is locked to the spring receiving portion and the other end biases the insulator toward the base of the lamp. Consists of a housed coil spring,
At the edge of the socket body on one opening side,
A notch recess is formed at a position extending in the axial direction from the drilling position of each of the engagement holes, and the inulator places each locking piece in the notch recess and presses the respective locking piece. 1. A lamp socket characterized in that each of the locking pieces is thin and flexible so that the pieces can be press-fitted into the socket main body while being bent and engaged with the respective engagement holes.
