Description

[Detailed Description of the Invention] [Industrial Application Field] This invention can be used in the field of automotive lighting, and particularly relates to a coupler mounting structure for a harness.

[Prior Art] In automotive lighting equipment, as shown in Fig. 5,
There is a light fixture a with a harness coupler b attached to the back side. In this case, the housing c of the lamp a
A hole is formed in the hole, a protrusion d is formed on the rear side of the coupler that fits into this hole, and the protrusion of the coupler is inserted into the hole of the housing, and the coupler is rotated approximately 90 degrees so that the protrusion is attached to the edge of the rear side of the hole. There is a means for attaching it by locking it to.

[Problems to be solved by the invention] In the case of the above conventional example, the housing c and the coupler b
If a gap is created between the coupler and the housing, rainwater, etc. may enter the lamp through the hole in the housing, causing trouble with the lamp, and there may also be drawbacks such as play in the mounting condition of coupler b, making it unstable. Ta. The present invention attempts to solve these conventional problems.

[Means for solving the problem] In order to solve this problem, the present invention provides a hole on the back of the lamp, and inserts and locks a protrusion provided on the back side of the coupler of the lamp harness into the hole. In an automobile lamp in which a coupler is attached to the hole, a sealing rib is provided around the hole and has an outer dimension that is included in the rear surface of the coupler where the projection is provided. It is.

[Function] When the rear surface of the coupler comes into pressure contact with the seal rib, the hole on the rear surface of the lamp is completely surrounded, which serves to prevent the intrusion of rainwater and the like, as well as to prevent rattling of the coupler.

[Example] Hereinafter, the present invention will be specifically explained with reference to the illustrated example. 1 is a housing made of synthetic resin;
A hole 1a for attaching a coupler to be described later is formed, and a circular sealing rib 1b is formed around this hole. As shown in FIG. 3, this seal rib 1b has an inclined surface of about θ=30° on the inside and a vertical surface on the outside, so that the cross section is approximately a right triangle, and the height is H.
is 0.8 to 1.5 m/m, and an R-shaped groove 1c is formed along the outer periphery. 2 is a coupler for harness, in the center of the upper part 2a on the back side,
A protrusion 2b is formed to fit into the hole 1a.

This coupler 2 can be assembled by inserting the protrusion 2b into the hole 1a of the housing 1 and turning it approximately 90 degrees to the right.
As shown in FIG. 4, the protrusion 2b is engaged with the rear side of the hole 1a for easy attachment.
At this time, the back side upper part 2a of the coupler 2 comes into pressure contact with the seal rib 1b, so that the hole 1a can be completely surrounded by this seal rib and the back side upper part 2a. Therefore, the seal rib 1b performs a complete sealing action, and can prevent the intrusion of rainwater and the like. Further, due to the elastic action of the seal rib 1b, no looseness occurs between the coupler 2 and the housing 1, and the attachment state of the coupler 2 is significantly stabilized. Note that when attaching the coupler 2, the seal rib 1b is attached to the rear upper part 2a of the coupler 2.
Its outer diameter is set in advance so that it is included in the upper part of the back side so that it does not protrude from the outside.

[Effects of the invention] As explained above, according to the invention, a sealing rib is provided around the hole in the housing, and the coupler is attached so as to come into pressure contact with this sealing rib, thereby preventing rainwater etc. from entering into the lamp. Moreover, it has excellent effects such as being able to firmly maintain the attached state of the coupler.
