Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a novel automotive lamp. Specifically, an object of the present invention is to provide a novel automobile lamp in which a light bulb-socket combination consisting of a light bulb attached to a socket can be temporarily fixed, and the manufacturing cost thereof does not increase too much. It is something.

BACKGROUND TECHNOLOGY AND PROBLEMS Recent automotive lighting equipment, particularly rear combination lamps, have become larger in size, and many have portions that wrap around to the sides of the vehicle body. In such rear combination lamps, due to problems with the structure and/or strength of the car body, a part of the car body is arranged in such a way that the part that wraps around to the side at the rear of the lamp is separated from other parts. It may be done. Such a case is shown in FIG. A is such a combination lamp for an automobile, and a light chamber b of a body c in which a plurality of light chambers b are integrally formed.
The lamp includes a lens d covering the opening of the lamp, and a light bulb e disposed in each lamp chamber b. The outermost light chamber bs corresponding to the wraparound lens part is formed with a slight distance from the other light chambers b, and when the lamp a is attached to the vehicle body f, the rear side of this light chamber bs is connected to the vehicle body f. It is covered by a part of the g is a back cover attached to the body c so as to cover the rear of the other light chambers b except for the outermost light chamber b; light bulbs are inserted through a light bulb holder (not shown) attached to this back cover g. e is held in the light chamber b, and the wiring related to the other light chambers b except for the light chamber bs are gathered in this back cover g. However, regarding the outermost light chamber bs,
Since the rear side of the light chamber BS is covered by a part of the vehicle body f at the time of installation, it is not possible to cover the rear side of the light chamber BS with the back cover g. That is,
If a back cover is attached to body C that covers even the light chamber BS, it is impossible to attach it to body F. Therefore, it is conceivable to connect the light bulb e in the light chamber bs and the wiring in the back cover g via a cord, but since the rear part of the light chamber bs is covered by a part of the vehicle body f, the cord cannot be connected. It cannot be made to follow the body. Therefore, conventionally, as shown in Figure 1, a light bulb e is attached to the light chamber bs via a removable socket h, and a connector i is attached to one end. Connect the other end of the cord j to the socket h, provide another connector k that opens on the side of the back cover g, and after assembling the lamp a to the car body f, connect the socket h to the socket h provided in the car body f. Light chamber through hole l
bs, and then connect connector i to connector k on back cover g.

However, in such a conventional lamp a, the socket h cannot be attached to the lamp chamber bs until the lamp a is assembled to the vehicle body f.
Therefore, if the connector i is connected to the connector k in advance, the socket h will be in a freer state, so the socket h will become loose during transportation or assembly work. This will not only result in poor workability, but also cause damage to the cord j, socket h, or bulb e. Therefore, the subassembly consisting of the bulb e, socket h, connector i, and cord j is kept separate from the lamp body a, and after the lamp body is assembled to the vehicle body f, the connector i is connected to the connector k of the back cover g. , socket h into the light chamber
Attachment to the bs is carried out. This eliminates the drawbacks mentioned above, but
This time, the number of items to be managed during storage and transportation has doubled, creating inefficiency in terms of management.At the same time, the lamp body a has been assembled to the vehicle body f and then transported separately. The subassembly must be taken out and assembled into the lamp body,
The workability is still not good.

Therefore, as shown in Figure 2, the lamp body m
An automobile lamp has been proposed in which a supporting wall n is provided protruding from the rear surface, a socket mounting hole o is formed in the supporting wall n, and a socket of a light bulb-socket combination is temporarily mounted in the socket mounting hole o. (Jitsukai 1976-
162803), but according to this, a slide core must be used in the mold to form the socket mounting hole o in the support wall n, which increases the mold cost, which is reflected in the cost. be.

Purpose of the invention Therefore, the present invention aims to provide a new automotive lighting device that can ensure temporary fixation of the light bulb-socket assembly until it is attached to the vehicle body, and that does not require high manufacturing costs. It is.
