Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp in which printed wiring is provided on the inner surface of a pack cup and pulp is held thickly laterally to reduce the overall thickness of the lamp. .
- Conventional vehicle lighting equipment, for example, as shown in Fig. 1, includes: - In order to hold the pulp a) - A pack carper provided on the rear surface of the housing H, and a holder C protruding from the inner surface of b. Enter,
Furthermore, the negative side cord f is sandwiched between the holder C and the socket d, and the socket d and the pulp pro metal part e are brought into contact to form a connection on the ground side. In addition, on the positive side, press the button contact 1 connected to the cord hI/c to the insulator j' and attach it to the insulator j'. I am doing something.

However, in such conventional vehicle lamps, the electrical connection between the socket d and the pulp pro metal part is achieved by the upward biasing force of the pulp pro metal part by the coil spring k. Inner surface of cut m and valve 20
This is the only part of the metal part e that makes contact with the upper part of the engagement cluster n, and the contact is poor, and the negative cord f is bent between the socket d and the holder 6 and 0 due to the clamping, so it is electrically The contact is not stable, and when using vinyl-coated wires, many cords such as cutting, welding, and crimping are required when modifying the wiring. The quality is extremely poor, and manual processing leads to incorrect wiring, which in turn increases the number of inspection steps.Furthermore, the rear signal light of the seedlings requires an increase in the number of pulps due to larger boards, more complicated wiring, and larger boards. This has increased significantly. For this reason, in recent years, although not shown in the drawings, lamps have been proposed that have been modified by installing a flexible printed treadle on the inner surface of the cover to eliminate problems such as wiring. In the lamp of this example, as in the example illustrated in FIG. The disadvantages are that the distance T to the bottom N of -b is long, which makes the entire lamp deeper, and the lamp must be thicker (larger).

Therefore, recently, although not shown in the drawings, a vehicle light using a pulp horizontal attachment method, in which the pulp is attached parallel to the inner surface of the pack cover, has been developed, and a light that aims to make the overall thickness of the light is thinner has been proposed. ``But--from 1917,'' for example. Light A
In order to assemble the holders, sockets, inserts, springs, button contacts, etc. using vinyl coated cord wiring to the KA-), cti, and 2-degree cover, the assembly work is done. It is complicated and difficult to assemble, and when the pulp is placed next to it, the pulp heat directly heats the pack cover, so there is a problem with the heat resistance of the back cover, so it is necessary to keep a distance of 1M degrees. For this reason, there are drawbacks such as the fact that the desired thickness of the lamp cannot be achieved with #1.

The present invention was developed in view of the above-mentioned circumstances, and the present invention is designed to automate wiring by using a conductor circuit board and to cover punctures in advance. By assembling two holder assemblies, such as a socket holder, which has been made into a holder, the assembly work is greatly simplified, and the pulp is placed horizontally, and a heat shielding slope is provided at the threshold between the seventh norib and the pack cover. Plan to make the entire light fixture thinner.]
