Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lamp housing for an electrical component for an automobile, and more specifically to a gasket holding structure for a lamp housing formed separately from an outer lens. It is something.

[Prior Art] Fig. 4 shows an electrical component for an automobile. The lamp housing 10 is provided with an apron part 10b for locking the outer lens 2 at the periphery of the opening 10a, and the inner circumferential surface is formed by performing optical inner surface treatment as necessary. The outer lens 2 is attached to the outer lens 2 via a gasket 3 to prevent water from seeping into the outer lens 2, and screw holes 4 are provided at appropriate locations where the apron portion 10b and the periphery of the outer lens 2 come into contact with each other. It was installed through the hole and assembled with screws.

The gasket 3 sandwiched between the apron portion 10b and the outer lens 2 is fixed by tightening the screws, and the gasket 3 is also attached to the vehicle body using the same screws, thereby reducing the installation work and cost. Ta. Incidentally, the gasket 3 may be fixed in advance to the periphery of the opening 10a of the apron or the like using an adhesive or the like.

[Problems to be solved by the invention] However, in conventional lamp housings, there is no structure to hold the gasket, and depending on where it is installed on the vehicle body, the gasket may just be caught on the periphery of the opening. The problem is that the gasket is placed in a very unstable condition and may fall off during installation or if the screws are not tightened, and the installation work is troublesome because the gasket is not fully retained. The dot was hot. Further, even when the gasket is fixed to the apron portion of the lamp housing with an adhesive or the like, there is a problem in that it takes time and extra cost to hold the gasket.

[Means for Solving the Problems] The present invention is a specific means for solving the above-mentioned conventional problems, in which an outer lens formed separately is attached to the opening via a gasket. In lamp housings for automotive electrical components,
an apron portion extending outward from the periphery of the opening;
A second apron part that is parallel to the apron part and extends further outward than the apron part with an appropriate gap is integrally molded by using a sliding mold, and the apron part and the second apron part are integrally molded. The present invention provides a lamp housing characterized in that a gasket is held in a groove-shaped portion formed between the lamp housing and the lamp housing, and the above-mentioned conventional problems are solved by providing a portion for holding the gasket at the periphery of the opening. It is something to do.

[Example] Next, the present invention will be explained in detail based on the illustrated example. In order to facilitate understanding, parts that are the same as those in the conventional example will be described with the same reference numerals, and descriptions of some overlapping parts will be omitted.

1 and 2 show a lamp housing of the present invention, and an apron portion 1b extending outward from the periphery of the opening 1a of the lamp housing 1.
and a second apron part 1c which is provided parallel to the apron part with an appropriate gap behind the apron part 1b and extends further outward than the apron part 1b. apron part 1c
A groove-shaped portion 1d into which a gasket is fitted is formed between the two. The lamp housing is molded using a mold, and the apron portion 1b and the second apron portion 1c are integrally formed by sliding the portion of the mold that is used to form the grooved portion. The wall thickness and protrusion width of each of the apron portions 1b and 1c, the width of the groove portion, etc. are also appropriately formed by making a mold.
Note that reference numerals 4 indicate screw holes provided at several locations, and the screw holes are set at appropriate angles so that they communicate with the mounting holes on the vehicle body side even when the outer lens 2 is arranged at an angle, for example. provide and form;
Moreover, it is provided in a position where it can be easily installed.

Further, the inner circumferential surface of the lamp housing can of course be provided with silver coating as in the conventional example, and an appropriate optical inner surface treatment may be applied as necessary.

FIG. 3 shows the lamp housing of the present invention holding the gasket. The gasket 3 is held by fitting into a groove-shaped portion, and an apron portion 1b, a gasket 3, and a second gasket are arranged at the periphery of the opening of the lamp housing in order from the opening side.
The apron portion 1c protrudes in a stepped manner and forms a contact surface with the periphery of the outer lens. Then, as shown in FIG. 3, the second apron part, which is larger than the first apron part, receives the gasket, and by bringing the seal part 2a of the outer lens into contact with this gasket,
A seal will be created.

[Effects of the invention] As explained above, the lamp housing of the automotive electrical component of the invention has a groove-shaped part formed from the apron part and the second apron part provided around the opening,
By fitting the gasket, which had been unstably placed around the periphery of the opening, into the groove and holding the gasket, the opening of the lamp housing is now close to vertical or facing downward. Even if the so-called gasket is installed on the vehicle body in a state where it is likely to fall off, such as in a state where the gasket is attached, it can be held by simply fitting the gasket into the groove, or by fixing it in an appropriate location using adhesive or the like. This has excellent effects such as saving the time and expense associated with holding the gasket, and making it easier to attach the gasket to the vehicle body.
