The vehicular lamp according to the present invention in this embodiment has the above-described configuration, and the wiring work will be described below. First, the film harness 2 is set on the lamp housing 1. At this time, the insertion hole 10 of the lamp housing 1 is aligned with the insertion hole 22 of the film harness 2 and the contact receiving portion 11 of the lamp housing 1 is
The opening 23 of the film harness 2 is fitted into the groove, and the covering cord 21 wired to the opening 23 is set in the groove 12 of the contact receiving portion 11 (see FIGS. 2 and 3). In this case, the contact receiving portion 11 of the lamp housing 1 and the opening 23 of the film harness 2 are positioned when the film harness 2 is set on the lamp housing 1, and the above-described setting is simple.

Next, the contact 3 is pressed and fixed to the contact receiving portion 11 of the lamp housing 1. At this time, the edge of the groove 33 of the contact 3 cuts the insulating coating 25 of the coating cord 21, and the connecting portion 31 (integral with the fixing portion 30) of the contact 3 and the core wire 24 of the film harness 2 are electrically connected. (See FIGS. 3, 4 and 6). In this case, the fixing (temporary fixing) between the lamp housing 1 and the film harness 2 and the electrical connection between the film harness 2 and the contact 3 are simultaneously performed. Moreover, there is no need to peel off the insulating coating 25 of the coating cord 20 or to solder the cord. Further, by fixing the contact 3, the film harness 2 can be prevented from coming off from the lamp housing 1.

On the other hand, wedge valves 4, 400, 400
Are detachably attached to the sockets 5, 500, 500, respectively, and the lead wires of the wedge valves 4, 400, 400 are electrically connected to the terminals of the sockets 5, 500, 500. Then, the wedge bulbs 4, 400, 400 and the sockets 5, 500, 500 are inserted into the insertion holes 10 of the lamp housing 1, and the sockets 5, 50 are inserted.
By turning 0, 500 around the axis, the sockets 5, 500, 500 are detachably attached to the edge of the insertion hole 10 of the lamp housing 1 via the attachment portion 50, and
Wedge bulbs 4, 400, 400 are arranged in the lamp room. At this time, the contact portions 32 of the contacts 3 are electrically connected to the exposed contact portions 51 of the sockets 5, 500, 500 (see FIGS. 4 and 5). In this case, the film harness 2 is easily fixed (finally fixed) to the lamp housing 1.

When a connector (not shown) on the power supply side is electrically connected to the connector-integrated socket 5 as shown by an arrow in FIG. 1, it is connected to the other sockets 500, 500 via the film harness 2. Power is supplied, and power is supplied to the three light source bulbs 4, 400, 400 via the three sockets 5, 500, 500. That is, 1
The power supply lines are distributed to a plurality of power supply lines via three sockets 5, 500, 500 and the film harness 2.

As described above, the vehicle lighting device of the present invention in this embodiment has only one socket 5, so that the wiring and the work of removing the wiring are simple. Also,
Since only the harness cord is wired from one socket 5, the wiring on the rear side of the lamp housing 1 is unified. Further, since the wiring can be easily removed, it is most suitable for recycling the lamp housing 1.

In particular, in this embodiment, since the film harness 2 is used, the following effects can be achieved. The covering cord 21 can be wired in a plane. It can be flexibly fitted to the shape of the lamp housing 1. The core wire 24 is hardly broken by the insulating film 20 and hardly broken.
Excellent waterproof. The type of the coating cord 25 can be unified. That is, the covering cord 25 can be made monochromatic. There is no need to use a tape or tape winding for bundling the covering cord 25.

In this embodiment, wedge bulbs 4, 400 and 400 are used as light source bulbs, but the present invention can be applied to other light source bulbs.

[0020]

As is apparent from the above description, in the vehicular lamp of the present invention, when power is connected to one of the plurality of sockets, power is supplied to the other sockets via the film harness. Power is supplied to all the light source bulbs. For this reason, since the wiring is only one socket, the wiring and the work of removing the wiring are simple.
