[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automotive lamp, and more particularly to a flexible printed wiring board connection structure for an automotive lamp using a flexible printed wiring board.

[0002]

2. Description of the Related Art FIGS. 13A and 13B are views showing the structure of a conventional automotive lamp, in which FIG. 13A is an assembled perspective view, and FIG. 13B is a partial longitudinal sectional view.

A bulb socket insertion hole 3 for inserting a front portion of the bulb socket 2 is provided in a bulb socket mounting portion 1a provided on a back portion of the automatic lamp body 1.

The valve socket 2 comprises a knob 21 formed at the rear, a central flange 22 and a front valve mounting portion 23, and abuts around the valve socket insertion hole 3 on the front of the flange 22. The part is provided with a seal member 22a formed of an elastic member such as rubber.

The bulb mounting portion 23 is provided with two engaging projections 23a at positions symmetrical with respect to the center axis of the bulb socket 2. The bulb socket insertion hole 3 of the automobile lamp body 1 is provided. Is inserted into the groove 3a provided in the groove.

A pair of connection terminals 24 formed of a conductive material such as copper is provided inside the seal member 22a, and will be described later when the bulb socket 2 is mounted on the vehicle lamp body 1. The electric power is supplied to the bulb (bulb) 5 attached to the bulb attaching section 23 through the internal wiring (not shown) by contacting the connecting section 42 a of the flexible printed wiring board 4.

FIGS. 14A and 14B show the structure of the flexible printed wiring board 4. FIG. 14A is a partial plan view thereof, and FIG. 14B is a vertical sectional view taken along the line AA in FIG. .

In the flexible printed wiring board 4, a conductive material 42 such as a thin copper plate is printed on a flexible first insulating sheet 41 (FIG. 14A), and the first conductive sheet 42 is further printed thereon. It is formed by covering with a second insulating sheet 43 of the same material as the insulating sheet 41 (FIG. 14 (a) shows that the second insulating sheet 43 is translucent and the conductive material 4
2 can be seen through), and since the predetermined wiring has already been made, the wiring is much easier than in the case of connecting a plurality of color-coded conductors as in the related art, and there is no possibility that the conductors are entangled with each other. .

In the center of the flexible printed wiring board 4, a valve socket insertion hole 44 for inserting the valve mounting portion 23 of the valve socket 2 is provided, and the wiring of the conductive material 42 is located in the vicinity of the valve socket insertion hole 44. The portion of the second insulating sheet 43 in contact with the connection terminal 24 of the valve socket 2 is removed, and the connection portion 4
2a is formed.

The bulb socket insertion hole 44 has substantially the same shape as the bulb socket insertion hole 3 provided in the bulb socket mounting portion 1a of the vehicle lamp body 1, but the cutout portion 44a is slightly larger than the groove 3a. Is formed in,
The valve socket 2 can be easily inserted.

Returning to FIG. 13 (b), the flexible printed wiring board 4 has an adhesive (or adhesive) 6 applied to one surface thereof on the back surface, and is tightly fixed to the bulb socket mounting portion 1a of the lamp body 1. The front portion of the valve socket 2 is inserted into the valve socket insertion hole 3 so that the engagement projection 23a passes through the groove 3a, the seal member 22a is pressed against the flexible printed wiring board 4, and the knob 21 is slightly rotated. The engagement projection 23a engages with the back surface of the bulb socket mounting portion 1a of the vehicle lamp main body 1 and is firmly fixed to the bulb socket insertion hole 3.

Since the front of the vehicle lamp body 1 is covered with a glass lens (not shown) or the like in a sealed state, the temperature rises by turning on the bulb 5 and the equipment is damaged by thermal expansion. Therefore, the air vent hole 7 (FIG. 13A) is provided, and the upper end 8a of the U-shaped waterproof cap 8 is attached to the projection 7a of the air vent hole 7.

The waterproof cap 8 has a through hole inside, but since the lower end 8b is oriented in the horizontal direction, there is a possibility that rainwater or the like may enter the automobile lamp body 1 from this portion. Absent.

[0014]

However, in the above-described conventional structure for connecting a flexible printed wiring board in a vehicle lighting device, since the bulb socket 2 is inserted into the center of the flexible printed wiring board 4, a large bulb socket is required. The insertion hole 44 must be provided, and therefore, as shown in FIG. 14A, the conductive material 42 of the other wiring must be routed around the valve socket insertion hole 44 largely. , The insertion hole 44
It is inevitable that the width of the flexible printed wiring board 4 is increased by the diameter of and the cost is increased. Also,
In the case where a complicated wiring is formed by the conductive material 42, the wiring is further complicated by bypassing the valve socket insertion hole 44, and the cost is also increased in that aspect.

The present invention solves such a problem and reduces the size of the flexible printed wiring board in the width direction, while at the same time ensuring a flexible supply of bulb power to the bulb socket.
