Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicular lamp having a socket holder.

[Conventional technology]

In a vehicle lamp having a socket holder, an elastic grommet is inserted into the interior of the socket holder, and a lead wire with an insulator attached is inserted into an insertion hole formed in the grommet to make the socket portion waterproof.

The above-mentioned socket is generally a metal cylindrical socket with a ground terminal spot welded to it, but if this spot welding is incomplete, accidents may occur where the ground terminal comes off and the lamp does not turn on. Was. It is also known to use a curling socket in which the socket and the ground terminal are integrally formed.

[Problem that the invention attempts to solve]

However, in both of the above cases, there is a problem in that although the waterproofness of the socket portion is taken into consideration, the waterproofness of the ground terminal portion is not taken into account.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention consists of a socket holder on the back of the lamp housing that is integrated with a socket insertion part and a grounding protrusion insertion part. A grommet to be inserted into the grommet is integrated with the grommet, and a thin-walled part is formed in the earthing protrusion insertion part of the grommet, the grommet is inserted into the socket holder, and the socket having the earthing protrusion is press-fitted onto the grommet. Then, the socket is assembled by piercing the thin walled part of the grommet with the grounding projection, and the thin walled part wrapped around the grounding projection waterproofs the interior of the lamp.

[Effect]

The fitting relationship between the grommet and the socket holder in which the socket insertion part and the grounding terminal insertion part are integrated is that the grommet is press-fitted into the socket holder by utilizing the elasticity of the grommet, so that there is no gap between the grommet and the socket holder. has a waterproof function. Further, since the socket is assembled to the socket holder by piercing the thin wall portion formed in the ground terminal insertion portion of the grommet with the ground terminal, the thin wall portion wraps tightly around the outer periphery of the ground terminal to provide waterproofing.

〔Example〕

Next, one embodiment of the present invention will be explained with reference to FIGS. 1 to 8.

FIG. 1 is a sectional view showing the overall structure of a vehicle lamp to which the present invention is applied, and FIG. 2 is a sectional view showing details of the socket holder shown in FIG. 1.

In FIGS. 1 and 2, 1 is a lamp housing, 2 is a socket holder assembled to the mounting part of the lamp housing 1, 3 is a lens that is mounted to a recessed part of the outer edge of the lamp housing 1 with an adhesive, etc., and 4 is a valve attached to the socket holder 2.

The socket holder 2 is attached to the attachment portion 1a of the lamp housing 1 by fitting. This socket holder 2 is made of synthetic resin or the like, and, as shown in FIG. 3, is integrally formed with a socket insertion part 2a and a grounding terminal insertion part 2b. The grommet 5 inserted into the socket holder 2 is made of an elastic member such as rubber, and has a socket insertion part 5a and a ground terminal insertion part 5b integrally formed as shown in FIG. The socket insertion part 5a has a plurality of holes 5c into which socket terminals are inserted, and the grounding terminal insertion part 5b has a hole 5d into which a grounding protrusion is inserted. A thin wall portion 5e shown in FIG. 7 is formed. The grommet 5 has a plurality of thin protrusions 5f on its outer periphery, and by press-fitting the grommet 5 into the socket holder 2 shown in FIG. 3, the thin protrusions 5f are crushed and the socket holder 2
A waterproof structure is provided between the grommet 5 and the grommet 5 as shown in FIG.

As shown in FIG. 5, the socket 6 attached to the grommet 5 is a curling socket in which a cylindrical socket part and a grounding protrusion 9 are integrally formed by punching a metal plate. An insulator 7 is assembled via a spring 7a. The lead wire 8 led out from this curling socket 6 and the grounding protrusion 9 are forcibly inserted into the respective insertion holes 5c and 5d provided in the grommet 5 in the socket holder 2, as shown in FIG. Assemble to. At this time, the thin wall portion 5e provided in the grounding projection insertion hole 5d shown in FIG. 7 is pierced by the grounding projection 9 as shown in FIG. It can be made waterproof. In addition, in the figure, 10 is a grounding cord connected to the grounding protrusion 9.

[Effect of idea]

As described above, according to the vehicle lamp of the present invention, the socket holder of the lamp is integrally formed with a socket portion and a grounding protrusion insertion portion, and the grounding protrusion insertion hole of the grommet fitted into the socket holder Since the socket is assembled to the socket holder by forming a thin-walled portion and piercing the thin-walled portion with the grounding protrusion of the socket, the inside of the lamp can be waterproofed by the thin-walled portion wrapped around the grounding protrusion. effective.
