Description

[Detailed Description of the Invention] The present invention relates to an automotive lamp, and more particularly to an improvement in the mounting structure of a socket holder for mounting a socket and a mounting body for mounting the socket holder.

As shown in FIGS. 1 and 2, a conventional automobile lamp has a socket holder a having a flange b formed thereon, and a holding piece C projecting upward from the flange b by a certain distance. On the other hand, a mounting body such as a housing d
Insert part a' above socket holder a and presser piece C.
A hole e and a recess f are formed, and the insertion part a' of the socket holder a and the holding piece C are aligned with the hole e and the recess f, and the socket holder a is attached so that the seven flange b is attached to the outer wall of the mounting body d. By inserting the socket holder a into contact with each other and then rotating the socket holder a, the holding piece C and the flange b sandwich the mounting body d, and thereby the socket holder a is assembled to the mounting body d. ing.

By the way, in the conventional automobile lamp shown above, the holding piece C of the socket holder a is provided above the flange b, so that the holding piece C is located inside the lamp chamber in the assembled state.

For this reason, it is not possible to visually check whether the socket holder a is reliably assembled to the mounting body d after assembly.

In order to improve this problem, lamps that allow the assembly status to be visually confirmed have been proposed (for example, Utility Model Application No. 54-114259), but the conventional lamps are difficult to position the socket holder relative to the mounting body. Since this is not done, the filaments of the pulp are not constant, and such a structure poses a problem in terms of light distribution characteristics.

In view of the above-mentioned conventional problems, the present invention not only makes it possible to check from the outside whether the socket holder and the mounting body are reliably assembled, but also enables the mounting of the socket holder to the mounting body. It is an object of the present invention to provide a lighting device for an automobile that can ensure positioning and improve assembly reliability.

The details of the present invention will be explained below with reference to FIGS. 3 to 7.

3 to 7 show an embodiment of a vehicle lamp according to the present invention.

In the figure, 1 is a socket holder, and 2 is a mount to which the socket holder 1 is attached.

As shown in FIG. 7, the socket holder 1 is formed into a cylindrical shape that includes an insertion part 1a for the mounting body and a socket holder main body 1b below the insertion part 1a.

A seven flange 11 is formed between the insertion portion 1a and the main body 1b.

The flange 11 is basically circular, but has a pair of notches lie formed at diametrically opposed outer peripheral edges.

That is, the flange 11 is cut out at a portion of its outer peripheral edge facing each other in the diametrical direction to form a portion Ha where the notch 11c is located and a circular portion Nb where the notch He is not.

Between the circular portion 11b of the flange 11 and the socket holder body 1b, there is a protruding wall 1 integrally formed therewith.
2 and 12 are provided.

That is, as shown in FIG. 7, the protruding walls 12, 12 each have the same height as the outer peripheral edge of the circular portion 11b, and are formed integrally with the socket holder body 1b from the circular portion 11b. .

Furthermore, between the portions 1, 1a where the notches are located and the socket holder main body 1b, there is a protruding wall 13°1 that is integral with the socket holder main body 1b.
3 is provided.

That is, the protruding wall 13. has the same height as the portion 11a, and hangs down from the portion 11a to form a socket holder body lb.
is formed integrally with.

Therefore, the height of the protruding wall 13 is shorter than the height of the protruding part 12.

On the other hand, the mounting body 2 is formed with a circular insertion hole 21 into which the insertion portion 1a of the socket holder 1 can be inserted, and in the illustrated embodiment is made of a back cover.

A pair of locking portions 22 for locking the socket holder 1 are provided on the outer surface of the mounting body 2 outside the insertion hole 21 .

That is, as shown in FIG. 5, the locking portion 22 has an upright portion 22a that stands outward and has approximately the same thickness as the flange 11 at a position diametrically opposed to the insertion hole 21.
In addition, a hook portion 22b extending toward the top of the insertion hole 21 is formed at the tip of the upright portion 22a.

The distance between the hook portions 22b of the pair of locking portions 22 is such that the portion 11a where the pair of notches of the 7 langes are located can be inserted through, but the other circular portion 11b cannot be passed through; The pair of engagement parts are connected to the part 11 where the flange has a cutout part.
insert part 1a of the socket holder with
When the socket holder 1 is rotated after inserting the socket into the insertion hole 21, the hook portion 22b presses the flange portion 11 against the outer wall of the mounting body 2, and the protruding wall 12 presses against the hook portion 22.
By colliding with b, the socket holder 1 can be positioned and attached to the mounting body 2 at a fixed angular position.

In addition, in FIGS. 3 to 5, 3 is a socket and 4 is a light bulb.

Since the automotive lamp according to the present invention has the above-described configuration, in order to assemble it, the notched portion 11a of the flange 11 and the locking portion 22 of the mounting body 2 must be aligned with each other at the insertion portion of the socket holder 1. 1a is inserted into the insertion hole 21 of the mounting body 2, and the flange 11 is brought into contact with the outer wall of the Sakai body 2 as shown in FIG. Since the portion 22 and the mounting body 2 sandwich the flange 11 and the locking portion 22 collides with the protrusion wall 12, it can be confirmed from the outside that the socket holder 1 is assembled to the mounting body 2. At the same time, the positioning of the socket holder 1 with respect to the mounting body 2 can be kept constant due to the collision between the protrusion wall 12 and the locking portion 22.

As a result, it is possible to prevent the socket holder from falling off as in the conventional case, and to perform reliable assembly in terms of light distribution characteristics.

In addition, in the present invention, since the projecting walls 12 and 13 function as the knobs during assembly, assembly is easy, and the flange 11 and the socket holder body 1b are connected to the projecting wall 12. , 13, the strength of the socket holder can be improved.

As described above, according to the present invention, it is possible to visually check from the outside whether the socket holder and the mounting body are reliably assembled, and in particular, it is possible to check the positioning of the socket holder during assembly. This has the effect of increasing assembly reliability.
