[Means to solve the problem]

This invention was developed by improving and eliminating the above-mentioned drawbacks of the conventional lighting lamp connector mounting structure.It expands elastically when inserted, returns to its original state after insertion, and retains one mounting piece of the connector. A plate-shaped holding piece with a narrow entrance and wide internal holding hole formed from one end along the direction of connector insertion, and the other mounting piece of the connector are fitted and supported so that they can slide along the direction of connector insertion. an L-shaped support member that forms a fitting groove together with the side wall surface of the lamp housing;
The connector is mounted opposite to the side wall surfaces of two lamp housings, and the side wall surfaces of the lamp housings serve as guide surfaces when inserting the connector.

[Effect]

The connector can be easily installed and fixed by inserting one mounting piece of the connector into the L-shaped support member and pushing the other mounting piece into the holding hole of the holding piece.

〔Example〕

Examples of this invention will be described below with reference to the drawings.

In FIGS. 3 and 4, reference numeral 15 is a lamp housing for a combination lamp that is attached to the rear of the vehicle. A lens 16 is attached to the front (rear of the vehicle), and a lamp mounting portion 17 is attached to the rear (interior of the vehicle). 1
8 is formed. This lamp mounting part 17,1
8 has an L-shape as a whole and is curved backwards to give it a bulge. 19, 20 are lamp mounting parts 17,
A lamp socket 18 is attached, and 21 and 22 are lamps. 23 is each lamp socket 19, 2
A connector connected to the ends of lead wires 24 and 25 led out from 0, and mounting pieces 2 are attached to the upper and lower end surfaces of the connector.
6 and 27 are integrally formed in the vertical direction. 28
is, for example, an L-shaped support member integrally formed in the longitudinal direction of the vehicle under the vertical surface 18a of the orthogonal outer surface of the lower lamp mounting portion 18, and the lower mounting piece 27 of the connector 23 is connected between the vertical surface 18a and the vertical surface 18a. A fitting groove 29 is configured to be slidably fitted. Reference numeral 30 denotes a holding piece that is integrally formed above and opposite to the L-shaped support member 28 from the upper end base of the lamp mounting part 18 toward the rear, and has an inlet 31a on its free end side as shown in FIG. A substantially circular holding hole 31 is formed with a narrow inner portion 31b and a wider inner portion 31b. The width of the entrance 31a of this holding hole 31 is made sufficiently narrower than the thickness of the upper mounting piece 26 of the connector 23.
Once pushed into the holding hole 31 beyond the entrance 31a, the attachment piece 26 is prevented from coming off thereafter.

With the above configuration, when attaching the connector 23, the connector 23 is placed along the lower lamp mounting part 18 of the lamp housing 15 with its opening side facing backward, and the lower mounting piece 27 of the connector 23 is attached to the lamp mounting part 18 of the lamp housing 15. The upper mounting piece 2 is inserted into the fitting groove 29 between the vertical surface 18a and the L-shaped support member 28.
6 into the holding hole 31 formed in the holding piece 30, and the fitting piece 26 is fitted into the inside 31b of the holding hole 31 beyond the entrance 31a, thereby completing the installation of the connector 23.

With the above mounting structure, the mounting pieces 26 and 27 of the connector 23 are connected to the corresponding holding holes 30 of the holding piece 30.
The connector 23 can be attached by pushing it along the fitting groove 29 between the vertical surface 18a of the L-shaped support member 28 and the vertical surface 18a of the lamp mounting portion 18 and the L-shaped support member 28, which simplifies the attachment work. In addition, in the installed state, the vertical surface 18a of the lamp mounting portion 18, the L-shaped support member 28, and the holding piece 30 prevent movement in the vertical direction and in the direction perpendicular to the sliding direction. Since it prevents movement in the sliding direction, it will not come off while driving. In addition, since the connector 23 is arranged in the front and rear direction of the vehicle body,
The lead wires 24, 25, etc. are aligned in the longitudinal direction of the vehicle body along the lamp housing 15, and do not spread out, making wiring easy.

[Effect of idea]

According to the present invention, by using the side wall surface of the lamp housing as a guide surface when inserting the connector,
When inserting the connector, it is sufficient to move the connector to the connector insertion start position by touching it against the side wall surface of the lamp housing, and then push it in as it is, and the insertion posture is stable from beginning to end.

In addition, the present invention has a structure for holding the connector on both sides.
One is elastically expanded into a holding hole with a narrow entrance for insertion, and the other is slidably supported in the insertion direction.This allows the connector to resist resistance when inserted. is only on one side and can be easily inserted with little force.

Furthermore, in the present invention, since the holding piece and the L-shaped support member are attached to the side wall surface of one lamp housing, the side wall surface of the lamp housing can be used as a guide surface when inserting the connector, and one of the holding pieces can be used as a guide surface when inserting the connector. It can also be used as a groove wall of a fitting groove that serves as a means, and the rigidity of the holding means is improved and the structure is simplified. Furthermore, since the connector can be attached closely to the lamp housing, the installation space can be reduced.

Of course, in the present invention, the connector can be attached and detached with one touch, and the structure can be simplified, the number of parts can be reduced, and the connector can be provided at low cost.
