Description

[Detailed Description of the Invention] This invention relates to a socket structure for a vehicle lamp.

Conventionally, in the socket of a vehicle lamp, by inserting the bulb while aligning the bulb pin with the J-slot groove provided in the socket body and rotating the bulb, the bulb pin is locked in the J-slot groove. In this socket, as shown in Fig. 1, an insulator c is mounted inside a bottomed cylindrical body a via a spring b, and when a valve d is inserted, The insulator c is pushed and the spring b is compressed, and the reaction force of this spring holds the valve d on the main body a, and the terminal e of the valve d and the terminal f of the insulator c are brought into pressure contact and an electrical connection is established. It is meant to be done. Reference numeral g denotes a power supply cord, which is introduced through a hole in the bottom of the main body a, and its tip is connected to the terminal f of the insulator c.

However, according to the conventional socket structure, since the spring b must be housed in the main body a, the depth of the main body a inevitably increases, which has the disadvantage of hindering the reduction in thickness of the lamp.

The present invention was devised to eliminate these conventional drawbacks, and attempts to provide a socket with a structure in which the spring is provided outside the socket body, and the base pin of the valve is engaged with the J-slot groove of the socket body. In the structure of the socket in which the valve is inserted while the socket body is stopped, a spring receiving portion is provided on the outer wall on the front end side of the socket body, and a part of the insulator that moves within the socket body is made to protrude from the socket body to accommodate the spring receiving portion. The main feature is that a spring is mounted between the spring receiving part and the spring receiving part of the socket main body so as to surround the socket main body.

Hereinafter, the present invention will be specifically explained with reference to the illustrated embodiments. Reference numeral 1 is a cylindrical socket body, and a spring receiving part 1a is provided protruding from the outer wall on the front end side (valve insertion side), and on the rear end side. Guide grooves 1b formed by notches are provided oppositely in the axial direction. Reference numeral 2 designates an insulator, and projecting pieces 2a that engage with the guide groove 1b are provided protruding from both sides, and the tips of these pieces are bent downward to form a spring receiving part 2b. 3
is a terminal provided on the front (upper surface) side of the insulator 2, to which a cord 4 for power supply is connected. The insulator 2 can be inserted into the socket body 1 by fitting the projecting pieces 2a into the guide grooves 1b of the socket body 1, respectively. At this time, the spring receiving part 2b of the insulator 2 is made to protrude outside the socket main body 1, and the coil spring 5 is attached between this spring receiving part 2b and the spring receiving part 1a of the socket main body 1, It is designed to surround the socket body 1.

The socket according to the present invention is constructed as described above, and when the valve 6 is inserted, the insulator 2 is pushed and the coil spring 5 is pulled, and the reaction force of the coil spring holds the valve 6 in the socket body 1 (not shown). Although this is omitted, the base pin of the valve is locked in the J-slot groove of the socket body as in the conventional case, and the terminal 7 of the valve 6 and the terminal 3 of the insulator 2 are brought into pressure contact and electrically connected.

According to the present invention, since the coil spring 5 is provided on the outside of the socket body 1, the length (depth) of the socket body is shorter than that of a conventional insulator in which a coil spring is provided between the insulator and the bottom of the socket body. Therefore, the amount of protrusion of the socket can be kept small and a thin lamp can be formed.
