Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a mounting structure for a wedge base bulb mounted on an automobile lamp or the like.

<Prior art> Wedge base valves are smaller and lighter than other valves, so conventionally the pinching portion 2 is connected to the valve socket B as shown in FIGS. 4 and 5.
By holding the terminal 5 assembled inside, the valve socket is attached and held. However, as wedge base valves have become larger, there has been a problem in that the wedge base valves tend to fall off or shift from the valve sockets due to vibrations, etc., resulting in poor electrical contact with the terminals in the valve sockets.

<Problems to be solved by the invention> The present invention has been developed in view of the above-mentioned problems in the past, and even when the wedge base valve becomes larger, the wedge base valve can easily become stuck in the valve socket due to vibrations, etc. It is an object of the present invention to provide a mounting structure for a wedge base valve that is free from the risk of falling off or shifting and causing poor electrical contact with the terminals in the valve socket.

<Means for Solving the Problems> The mounting structure of the wedge base valve of the present invention that achieves the above purpose has a structure in which the wedge base valve is provided with wires on both the left and right sides of the pinching part of the wedge base valve that are closer to the lead wires exposed on the pinching part. An engaging groove is horizontally recessed in the upper position, and an appropriate number of latch claws that engage with the engaging groove are protruded upward to allow elastic swinging on the rim of the valve mounting opening of the valve socket. It is characterized by the fact that it was established.

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

The wedge base bulb A conforms to the standard, and has a flat pinching part 2 formed in the lower part of the light bulb part 1, and a filament 3 in the light bulb part 1.
The lead wire 4 connected to the pinching part 2 is exposed from the lower end of the pinching part 2 on both left and right sides.

The pinching part 2 of the wedge base valve A has an engaging groove 7 on both left and right sides for engaging the latching claw 6 of the valve socket B, and the upper end of the lead wire 4 exposed on the pinching part 2. A recess is formed in the horizontal direction at the upper position.

On the other hand, the valve socket B has an appropriate number of latching claws that can be elastically swung upward from the mouth edge of the valve mounting opening 8 of the valve socket B in correspondence with the engaging groove 7 formed in the pinching part 2 of the valve. 6 are formed in a protruding manner, and the right and left sides of the pinching portion 2 of the valve A are supported by the latching claws 6 in a resilient clamping manner. In addition, 9 in the figure is the pinching part 2 of valve A.
These are elastic support claws for supporting both sides of the

<Effects of the invention> Since the mounting structure of the wedge base valve of the present invention is configured in this way, when the wedge base valve is mounted on the valve socket, the pinching part is pinched by the terminal built into the valve socket and at the same time The latching pawl of the valve socket is elastically engaged with the engaging groove formed in the upper part of the pinching part in a pinching manner. As a result, even when the wedge base valve becomes larger, there is no risk of the wedge base valve falling out of the valve socket due to vibration, etc., or shifting and causing poor electrical contact with the terminals of the valve socket. .

Moreover, the engagement groove of the pinching part that engages with the latch claw of the valve socket is formed above the lead wire exposed on the pinching part, so that the wedge base valve can be held more stably. At the same time, the latch claw of the valve socket can be reliably engaged with the engagement groove of the pinching portion without being obstructed by the lead wire of the wedge base valve or the terminal of the valve socket.

Therefore, the intended purpose can be achieved.
