Description

[Detailed Description of the Invention] The present invention relates to a vehicle light, and more particularly to a vehicle light having a synthetic resin housing having a parabolic reflector formed on the inner surface and a wire holding portion provided on the outer surface. .

A conventional vehicle lamp of this type is shown in FIGS. 1 and 2. In Figures 1 and 2, a is a lens, b is a housing, the leg part d of the lens a is adhesively fixed to the groove c formed around the housing b with a sealant e, and the light source bulb f is arranged inside. It has been set up. A parabolic reflector is formed on the inner surface of the housing b, and two holding pieces h having opposing protrusions g and g are formed on the outer surface, and the holding pieces h are integrally molded from synthetic resin. It has a structure in which the electric wire is inserted and held between the holding pieces h and h, and since there are protrusions g and g, it is necessary to cut out the mold, so the entire space between the holding pieces h and h is an opening k, and the part of this opening k is Since no reflecting mirror is formed, when the light source bulb f is turned on, a dark part l appears on the lens a, and the electric wire m is
Even if the opening k is maintained, light leaks from the opening k to the rear of the housing b, which poses problems in terms of appearance and functionality.

The present invention aims to provide a vehicle lamp that improves the drawbacks of the conventional lamps as described above.

Embodiments of the present invention will be described in detail below with reference to FIGS. 3 to 5.

1 is a lens, 2 is a housing, and the lens 1 has a leg portion 4 adhesively fixed to a groove 3 formed around the housing 2 using a sealant 5. A light source bulb 6 is supported within the housing 2 by a socket 7 attached to the housing 2. housing 2
is integrally molded from synthetic resin, having a reflecting mirror part 8 such as a paraboloid formed on the inner surface, and a pair of holding pieces 10, 10 having an L-shaped cross section and opposing protrusions 9, 9 on the outer surface. , and a small hole 11 having a diameter of about 3 mm is formed in the housing portion between the holding pieces 10, 10.

When the holding pieces 10, 10 are integrally molded with the housing 2, a small hole 11 is formed between the holding pieces 10, 10.
Once formed, it can be molded by forcibly cutting out the mold using a slide core 12 as shown in FIG. That is, 13 is a mold on the core side, 14 is a mold on the cavity side, these molds 13 and 14 are used to mold the main body of the housing 2, and the holding pieces 10 and 10 are made of the core mold 13 and the slide core 12. Molded by. The slide core 12 is slidably provided on the core mold 13, and has protrusions 9,
9, and an enlarged portion 16 that forms a molding space for the holding pieces 10, 10 by the core mold 13.
and a protrusion 17 at the tip. With such a mold groove construction, when the housing 2 is molded and the core mold 13 and cavity mold 14 are opened,
By protruding the protrusion 17 of the slide core 12, the protrusions 9, 9 of the holding pieces 10, 10 can be forcibly removed from the recess 15.

6A to 6D are explanatory diagrams showing the state. After molding the housing having the holding pieces 10, 10 in the state shown in FIG. 6A, the core mold 13 is opened as shown in FIG. When the ejector pin 18 is pushed out and the protrusion 17 of the slide core 12 is pushed up as shown in FIG.
2 escapes from between the holding pieces 10, 10, and when the escape is completed, the pair of holding pieces 10, 10 are restored as shown in FIG.

The vehicle lamp of the present invention is constructed as described above, and the electric wire 18 can be held in the space formed by the outer surface of the housing 2 and the holding pieces 10, 10 having the protrusions 9, 9. In this case, the protrusion 1 of the slide core 12 is located between the holding pieces 10, 10.
There is only a small hole 11 with a diameter of about 3 mm made by 7, and the space between the holding pieces is not completely open like in the conventional one, so the ineffective part of the reflector part 8 on the inner surface of the housing 2 is only the small hole 11, and the light source bulb When the lens 6 is turned on, there is almost no ineffective portion in the reflecting mirror portion 8, so that no dark portion is generated on the lens 1. Further, since the small hole 11 is an extremely small opening, the light from the light source bulb 6 is blocked by the thickness of the housing 2, the holding pieces 10, 10, the protrusions 9, 9, etc., and almost no leakage to the outside occurs.

As described above, according to the present invention, when the light source bulb is turned on, there is no dark area on the lens or light leaking to the rear of the housing, which is extremely beneficial in terms of appearance and function. .
