In the wiring structure of the vehicle lighting device to which power is supplied, the connection between the flexible substrate and the socket and / or the vehicle body-side coupler is made in two substantially parallel opposite surfaces formed in the housing of the vehicle lighting device. By inserting the connection portion of the terminal provided with a substantially U-shaped board connection portion for elastically pressing the exposed surface of the conductor portion of the flexible substrate into the recess having the two surfaces by inserting the connection portion into the recess. And the socket terminal and / or the vehicle body-side coupler terminal are exposed on the flexible substrate. By providing a wiring structure of a vehicle lamp, characterized in that through the body portion is screwed to the housing of the vehicle lamp is intended to solve the conventional problems.

【Example】

Next, the present invention will be described in detail based on an embodiment shown in the drawings. FIGS. 1 and 2 show an embodiment in which the present invention is applied to a connection terminal 1 of a vehicle lamp 10 connected to a vehicle body-side coupler 20. A housing 11 of the vehicle lamp 10 has two opposing parallel surfaces. 12
A recess 12 having a and 12b and a slit-shaped opening 13 are provided at the same time, for example, when the housing 11 is molded. The flexible board 2 has a conductor portion 2b formed of a copper foil or the like exposed by removing the cover film 2a at a position corresponding to the concave portion 12, and the exposed conductor portion 2b is It is to be fitted along the surfaces 12a, 12b. In addition, in the present invention, the connection terminal 1 is formed using a member having high conductivity and elasticity such as brass, for example, and the connection terminal 1 is formed at one end in a substantially U-shape. A substrate connecting portion 1a elastically pressed against the two surfaces 12a and 12b of the concave portion 12, and a blade portion 1b fitted to the vehicle body-side coupler 15 at another end; When the connecting portion 1a is fitted into the concave portion 12, the blade portion 1b is configured to penetrate the opening 13 and protrude to the outside of the housing 11. Further, a boss 14 is provided between the recess 12 and the opening 13 of the housing 11, and fits into a mounting hole 1c provided between the board connecting portion 1a and the blade portion 1b of the connection terminal 1. It is possible. FIG. 3 shows a joint state between the flexible board 2 and the connection terminal 1. The conductor 2b of the flexible board 2 is connected to the two surfaces 12a, 12b of the concave portion 12 and the board connecting section.
1a is elastically sandwiched between the flexible substrate 2 and the connection terminal 1 by the contact pressure, so that good conductive characteristics between the flexible substrate 2 and the connection terminal 1 can be obtained. It is fitted by 1c and fixed by means such as thermal caulking performed on the boss 14. FIG. 4 shows an example of the arrangement of the connection terminals 1 on the surface of the housing 11. Four blade portions 1b of the connection terminals 1 are arranged in a substantially rectangular shape as shown in FIG. By forming a case body 15 of an appropriate shape on the outer surface of the vehicle, a 4-P body-side coupler 20 can be mounted. Can be supplied. FIG. 5 shows an example in which the present invention is applied to the wedge base socket 3, and the light bulb terminal 4 is provided at one end with a board connecting portion 4a similar to the previous embodiment. A bulb connection 4b of known shape suitable for holding the wedge base 5a of the bulb 5 on the other side and making an electrical connection
The bulb terminal 4 is attached to the housing 11 in the same manner as in the previous embodiment, for example, the boss 14, and the sheath-shaped socket holder 6 is attached. A base socket 3 is obtained. With the above configuration, the wedge base socket 3 does not have a sliding portion with the flexible substrate 2, especially the conductor portion 2b even when the light bulb 5 is attached / detached. It is assumed that the conductor portion 2b of the extremely thin flexible substrate 2 is not damaged. The configuration described above can be changed as appropriate. For example, as shown in FIG. 6, the conductor portion 2b of the flexible substrate 2 extends beyond the recess 12 so that the mounting hole of the connection terminal 1 is formed.
If the housing 11 is extended to 1c and fixed to the housing 11 with screws 7 instead of the boss 14, electrical connection can be performed even at this portion, and further reliability can be obtained, and furthermore, The screw 7 is omitted by omitting the recess 12 as well.
It is also possible to make the electrical connection only with the fixed part by the above.

[Effect of the invention]

As described above, according to the present invention, the connection between the flexible substrate and the wedge-base socket and / or the vehicle-body-side coupler is made in the recess formed in the housing of the vehicular lamp and having two substantially parallel opposite surfaces. By inserting the substrate connecting portion of the terminal provided with a substantially U-shaped connecting portion that elastically presses the exposed surface of the conductor portion of the substrate into pressure contact, the fitting portion is fitted along the two surfaces by inserting the terminal connecting portion into the concave portion. First, when implemented as a connection terminal with the vehicle body side coupler, one wedge base socket for each series is provided with a coupler terminal, and the number of series Only the vehicle body couplers connected to each other can be gathered at one place, thereby achieving an excellent effect of simplifying a complicated process of mounting the vehicle lamp on the vehicle body. Secondly, when implemented on the wedge base socket, it is possible to fix the wedge base socket to the lamp, and do not cause sliding with the conductor of the flexible board even when attaching or detaching the bulb, The effect of preventing breakage and improving reliability is achieved.
