Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a vehicle lamp, such as a tail lamp, in which a plurality of light bulbs are mounted in one housing.

[Prior art]

For example, when two light bulbs are installed in one housing, as shown in FIG.
The sockets 2A and 2B of 1B are arranged back to back and fixed to the holder 3 individually, or both the sockets 2A and 2B are welded to the bracket 4 and an integrated structure is fixed to the holder 3.

The interior of the socket has a terminal 5 that can move forward and backward in the axial direction, and is connected to the outside via a cord 6. The terminal 5 is fixed to an insulating member 7 and is configured to move in the axial direction as the coil spring 8 expands and contracts.

However, such a structure requires a plurality of sockets, each of which must be separately fixed to the holder 3 or welded together via the bracket 4. Additionally, there is a limit to how shortening the valve pitch can be done.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle lamp that has a simple structure and can reliably mount two light bulbs in a predetermined arrangement relationship.

[Summary of the idea]

The present invention uses a vehicle light fixture in which multiple light bulbs are installed in the housing, and a connector is attached to the middle of the side surface of a metal cylinder, and the contact made of the leaf spring is used as the contact part with the contact point of the light bulb. A slit is formed in each socket to serve as a guide for inserting a light bulb, creating an integrated socket holder.

〔Example〕

Figures 1 to 3 show an embodiment of the present invention, in which a metal cylinder 11 with a length of about two sockets is shown.
From both ends, J-shaped slits 12A, 12B are inserted.
is formed to serve as a guide for the plug-in base of the light bulbs 21A, 21B, and a connector mounting hole is provided in the middle to mount the connector 13. This connector 1
3 is a locking hook 13 on both sides of the insulator 13A.
B, each has a partition piece 13C in the center, and leaf springs 14A, 14B pass through both sides of the partition piece 13C, and the inner protruding parts are the light bulbs 21A, 2.
It becomes a contact with contacts 22A and 22B of 1B. This portion is curved so that the light bulbs 21A and 21B form a protruding surface. The outer protruding portions of the leaf springs 14A, 14B serve as contacts with the joint coupler 31.

Note that a mounting piece 15 is formed on the side surface of the cylinder 11.

In this way, the connector 13 is attached to the middle of the side surface of the metal cylinder 11, and the leaf springs 14A, 14B are used as contacts with the contacts 22A, 22B of the light bulbs 21A, 21B, and each half of the cylinder 11 is used as a guide. By forming the slits 12A and 12B to form a so-called integrated socket holder, the socket housing can be easily fixed, and the valve pitch can be shortened from about 100 mm to about 80 mm. Furthermore, by attaching the connector 13, a complete socket can be obtained, simplifying the structure and reducing the number of parts.

〔effect〕

As described above, according to the present invention, one cylinder has two
Since the socket has the function of an individual socket and a connector is attached in the middle to form a complete socket, the socket and its fixing structure to the housing can be simplified, and the light bulb can be installed securely. It's coming. Also, since it is an integrated type, the valve pitch can be shortened.
