Description

[Detailed description of the invention] This invention relates to the structure of a vehicle light fixture that uses a flange light bulb, especially the attachment part of a headlight connector.The purpose is to reduce the number of parts and The purpose is to simplify the structure, simplify the work of replacing light bulbs, and obtain a product that is as inexpensive as possible.

Looking at the structure of a headlight that uses a commonly used flange light bulb, the flange of the flange light bulb is inserted into the flange fixing bracket fixed to the rear surface of the reflector, and the flange is further pressed from behind. In order to fix the metal fitting, a specially shaped spring is loaded into the metal fitting to maintain vibration resistance, and the connector is fitted into the metal fitting in such a state.

Therefore, the flange fixing bracket is indispensable, which increases the number of parts, naturally increases man-hours, and requires space, so the connector position is moved back and forward. The space protruding from the back of the lamp is large, making it difficult to replace the light bulb in a narrow space, and the product price is also high.

This proposal aims to eliminate the drawbacks of sloping as much as possible.
Hereinafter, a specific configuration of one embodiment will be described in detail with reference to the drawings.

Fig. 1 is an exploded perspective view of the headlamp according to the present invention, where L is a lamp body with a reflecting part formed on a substantially parabolic surface, B is a locking part protruding to the rear of the lamp body, and ■ is a light bulb. This is a flanged light bulb that has a flange almost at the center of the cap.As shown in Figure 2, the locking part B is an annular receiver on both sides of the seat W, with the tips facing each other in an L-shape. The locking protrusions 1, 1 are bent and have a locking hole drilled at their tips, and a stopper S is provided below the protrusions, respectively, and these pieces are fixed to the rear surface of the lamp body.

Note that the receiver may not have the seat W and the locking protrusions 1, 1 and the stopper S may be formed integrally with the lamp body.

K is a connector which, as shown in the perspective view in Fig. 3A, has a substantially convex shape, and is provided with cutout steps E with retaining protrusions N formed on both sides. Send one to
Cord insertion hole, approximately U-shaped, h2. H3 is perforated as shown in the figure, and its bottom has a bulge as seen in the opening of the same figure, and the left and right ones are
The one in the center is like an L-shape when opposed to each other.
Inside the left and right ones, there are terminal insertion holes h'l as shown in the figure.
h'2. As shown in an enlarged perspective view in FIG. 4, on the surface C where h'3 is in contact with the locking part B fixed to the lamp body, each of the terminal insertion holes and the cord are formed in the shape of a ■ character. Each electrode PI of the flanged light bulb is connected to the insertion hole.

P2. Electrode insertion hole h″1.h″2. h″
3 are provided with holes, respectively, and as shown in the figure, each contact t to which a cord l' is connected is loaded into the connector K having such a shape.

Since this projector is constructed in a diagonal manner, the operation and effect as well as the installation procedure will be described below with reference to Fig. 1. The receiver of the locking part B is inserted so as to be in contact with the seat W, and in this state, the connector K is inserted into each terminal insertion hole h'l, h'2. h'3 is each electrode P of the light bulb, P2. Place it so that it matches P3, and press it downward until the engaging protrusion N of the connector fits into the locking hole at the tip of the locking protrusion l of the locking part B. .

As shown above, according to the present invention, the connector is not inserted in the axial direction of the bulb, as is the case with conventional models, and there is no flange fixing metal fitting that occupies wasted space in the axial direction. Therefore, there is no need for a specially shaped pressing spring, and it is sufficient to simply press in a direction perpendicular to the axial direction, making it particularly easy to replace the light bulb, even in the narrow space of the car body. Not only can it be operated without difficulty, but it also has excellent vibration resistance because the notch step E formed on both sides of the connector in the fitted state is sandwiched by the locking protrusions L. Moreover, the number of parts is small and the manufacturing man-hours can be reduced.
Therefore, there are various excellent effects that can achieve the intended purpose of the present invention, such as the ability to obtain inexpensive products.
