Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to a light bulb socket for an automobile lamp, and more specifically, to a socket for attaching a light bulb with a pair of base pins protruding from the base. It concerns sockets.

<Prior art> This type of socket is firmly attached to the supporting part of the lamp body, and in particular, in the case of a socket for mounting a double filament bulb, it is necessary to prevent the insulator, which is the contact point of the bulb, from rotating into the socket body. It is necessary to install it.

Therefore, in the conventional socket of this kind, as shown in Fig. 1, a separately molded mounting bracket (B) is welded to the socket body (A) in order to attach the socket body (A) to the supporting part of the lamp body, and also prevents the insulator blade from rotating. In order to do this, the insulator's engaging claw C' was engaged with the guide elongated hole D drilled in the socket body A.
In manufacturing the socket, there were inconveniences such as poor workability and high cost.

<Problems to be Solved by the Invention> The present invention aims to eliminate these inconvenient manufacturing drawbacks of conventional sockets and to provide a socket for an automobile lamp that is easy to work with and can be manufactured at low cost.

<Means for Solving the Problems> The socket of the present invention automobile lamp which achieves the above object has a socket body formed in a substantially cylindrical shape with a J-slot formed at the open end thereof for hooking the base pin of the bulb. In a socket for an automobile lamp in which an insulator having a contact point with a bulb is installed inside, the central part of the peripheral wall of the socket body is gouged out and bent horizontally to form a mounting wing, and the mounting wing is It is characterized in that a protruding engagement groove is formed at the root portion of the insulator to engage the engagement claw of the insulator.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The socket body 1 is made by curling a single band-shaped metal plate and forming it into a cylindrical shape with a diameter slightly larger than the diameter of the mouthpiece of the valve A. The insulator 2 and the elastic spring 3 are housed inside the cylindrical shape. Drill J slots 4, 4 to hold the cap pin B of valve A,
Furthermore, the central part of the peripheral wall is gouged out and bent horizontally to form the mounting wing 5, and the engaging claw 2a of the insulator 2 is attached to the base of the mounting wing 5.
The engaging convex groove 6 is formed in a bulging manner.

The insulator 2 is formed into a disk shape as in the conventional case, and has contacts 7, 7 that electrically contact the valve A in the center thereof, and a cord 8 is connected to each contact 7, 7, and Engagement claws 2a that engage with the engagement convex grooves 6 of the socket body 1 are formed protruding from the same body at two locations on the left and right sides.

At this time, the left and right engaging claws 2 of the insulator 2
a and 2a are formed with different sizes to prevent reverse assembly.

The mounting wings 5 are used to attach the socket body 1 to the supporting part (not shown) of the lamp body.The mounting wings 5 are used to attach the socket body 1 to the supporting part (not shown) of the lamp body. They are integrally formed to protrude, and a screw hole 9 is bored in the center of the mounting wing 5. The mounting wings 5, 5 are bent so that the socket main body 1 faces slightly upward when mounted on the lamp body.

The engagement convex groove 6 that engages and supports the engagement claw 2a of the insulator 2 is formed by bulging the entire root portion of the mounting wing 5 outward along the longitudinal direction of the socket body 1, so that the insulator 2 can be inserted into the socket. It serves as a guide when the main body 1 moves along the longitudinal direction, and also serves as a stopper for the insulator 2 to rotate.

<Effects of the invention> In this way, the present invention scoops out the central part of the peripheral wall of the socket body and bends it horizontally to form the mounting wing, and engages the engagement claw of the insulator with the base of the mounting wing. Since the engagement convex groove is formed in a bulging manner, the mounting wing for attaching the socket body to the support part of the lamp body can be molded into the same body as the socket body, and the engagement wing for preventing rotation of the insulator can be formed. The convex groove can also be formed at the same time as the mounting wing is molded, so that the workability of the socket can be significantly improved compared to conventional sockets, and the socket can be manufactured at low cost.

Furthermore, the engaging convex groove that engages and supports the engaging claw of the insulator prevents the insulator from rotating, and at the same time serves as a guide when the insulator moves along the longitudinal direction of the socket body. The process becomes smooth and valve replacement becomes easy.

Therefore, the intended purpose can be achieved.
