Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a vehicular lamp, and more particularly to a vehicular lamp in which a conductor plate is provided in the housing and the pulp is held horizontally to reduce the overall thickness of the lamp. For example, as shown in Fig. 1, the lamp has a holder C protruding from the inner surface of an I-Using (back cover) b to hold the pulp a, and a metal cylindrical socket in the holder C. , and then sandwich the negative cord f between the holder 〇 and the socket d, and bring the socket d into contact with the pulp pro metal part e to connect the cord f to the ground side.

connection. On the positive side, a button contact l with a conductor terminal dotted at the end of the cord h is crimped and attached to the insulator j, and this is pressed into contact with the positive terminal t of the pulp a by a fill spring k for connection.

In the conventional vehicle lamp having such a configuration, the socket d
The electrical connection between the inner surface of the socket d (2) J slot m and the upper part of the retaining protrusion n of the Palpro metal part e is established by the upward biasing force of the PalPro metal part e by the coil spring k. This is only the part that makes contact with the holder C, and the contact is poor, and the negative cord f is pressed into contact with the holder C by clamping it between the socket d and the holder C, so the electrical contact is unstable.

In addition, the arrangement uses #'i vinyl-covered electric wire.

When performing wiring work, multiple processes such as cutting, welding, and caulking must be performed, which results in extremely poor productivity of the lighting fixtures, which leads to incorrect wiring due to manual processing, and even inspection work. In addition, since the pulp a is arranged in the Y-Y axis direction perpendicular to the inner surface of the nousing b, there is a drawback that the leading edge of the pulp a becomes backward (thick) in the nousing b.

Therefore, recently, although not shown in the drawings, pulp has been installed parallel to the 20 inner surfaces of the housing. Further, wiring has been improved by using printed circuit boards to eliminate p-miswiring.

However, the holder for the housing.

Assembling sockets, incinerators, springs, terminals, contacts, etc. is complicated and difficult to assemble, and when pulp is placed on the side, the heat of the pulp directly heats the rear side plate of the housing. Depending on the heat resistance of the housing, it was necessary to provide a certain degree of heat resistance, and for this reason, it was not possible to reduce the thickness of the tenon lamp as expected.

This invention was made in view of the above circumstances, and its purpose is to improve the efficiency of wiring by suspending a printed circuit board. On top, the assembly work is greatly simplified by assembling a pre-united socket holder integrally into the housing from the outer surface of the rear side plate;
