Description

[Detailed Description of the Invention] This invention relates to an improvement of a socket holder for an automobile lamp.

There is a socket holder which is attached to a reflector of an automobile lamp by caulking and locks the socket to form a light source part of the lamp. This type of socket holder has a cylindrical body a as shown in Figure 1.
A caulking part c for attachment to the reflector b is formed at the end of the reflector b, and a J-slot d for locking a socket (not shown) is cut out in the side wall of the main body a. In this case, the J-slots d are usually provided at three locations and are formed by notches from the edge of the main body a, so there is a drawback that the thickness of the material of the socket holder main body a cannot be made thinner for reasons of strength. In addition, as a result, the caulking part c, which is integrally formed with the main body a, becomes considerably thicker, requiring strong clamping force during caulking work, which not only makes the work difficult, but also when the reflector b is made of synthetic resin. This has the disadvantage of damaging or deforming the reflector. In order to prevent such inconvenience, it is possible to form a caulking ring e separately from the main body a' and attach it to a synthetic resin reflector using this caulking ring e, as shown in Figure 1B. However, the disadvantage is that the installation work is troublesome and the cost is high.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional sockets, and an object thereof is to provide a socket holder that can be formed from a thin metal plate, is easy to install, and has excellent performance. In order to achieve this object, the present invention has a structure in which the socket holder body is formed into a flap shape, and a J-slot hole is punched in the side wall of the socket holder body.

Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiments. Reference numeral 1 denotes a socket holder main body, the end portion of which is formed in the shape of a lapper whose diameter gradually increases, and a flange 1a is formed on the other end. A caulking part is provided integrally. Reference numeral 2 denotes J-slot holes punched in the side wall of the main body 1, and these are provided at at least three locations from the inclined side wall to the vertical wall of the main body 1.

The socket holder constructed in this way is used by inserting the caulking part b into the attachment hole of the reflector 3 and fixing it by caulking, as shown in FIG. Then, the valve 5 is inserted into this socket holder via the valve ring 4, and the socket 6 is also inserted, and the claw piece 6a formed at the tip of the socket is locked in the J slot hole 2. A valve 5 and a socket 6 can be attached. A terminal plate 8 is mounted inside the socket 6 via a coil spring 7, and this terminal plate is electrically connected to a lead wire 9. The terminal plate 8, which is biased forward by the coil spring 7, is connected to the valve. 5 is pressed and held, the valve is energized, and the socket 6 is urged rearward by the action of the coil spring 7, so that the socket 6 can be held. Note that 10 is a socket cover, which is fitted and attached to the flange 1a of the socket holder.

Since the socket holder according to the present invention has a structure in which the J-slot hole 2 is formed by punching, there is no notch on the edge of the socket holder main body, and the rigidity can be increased compared to the conventional one. Therefore,
It can be formed from a thinner metal plate than conventional ones, making it easier to caulk and attach the reflector to the reflector, and even if the reflector is made of synthetic resin, it will not be damaged or deformed. Further, since the socket holder is formed into a flap shape, the socket can be inserted and locked easily and securely even if the J slot hole is not a notch hole. Furthermore, since there is no notch on the edge of the socket cover as in the conventional case, it is possible to prevent injury during installation work, and the workability is good as the socket covers do not get caught in each other during the plating work, which improves workability and prevents deformation. It also has the advantage of being able to prevent this.
