Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for attaching a coupler to a vehicle lamp.

[Conventional technology]

Traditionally, when connecting a power supply cord or the like to the light source of a vehicle lamp, a resin coupler made by combining the ends of multiple cords has been used, making the connection process easier and improving work efficiency. It was effective.

Since there is a concern that the coupler itself may break due to vibration during driving, it has come to be fixed to the socket cover or lamp housing of the lamp, especially those that are attached to the lamp housing. As shown in FIGS. 3 to 5, an L-shaped piece c is provided on both sides of the bottom surface b of the coupler a, a pair of locking grooves d are provided, and a part of the lamp housing is recessed rearward. Coupler mounting part e formed integrally with
has a flange f that protrudes from left and right sides and is latched to the locking groove d, and a projection h that is latched to a hole g drilled in the mounting surface between the flange f on the bottom surface of the coupler. By inserting and sliding the collar portion into the locking groove of the coupler, the protrusion locks into the hole and the coupler is fixed to the back surface of the lamp housing.

[Problem that the invention attempts to solve]

However, in the case of the above-mentioned conventional lamp housing, since the coupler mounting portion is formed by recessing as described above, when a reflective surface is formed on the inner surface, a large recess is formed in the reflective surface. As a result, there was a problem in that visibility when the lamp was turned on was extremely poor.

[Means for solving problems]

The present invention has been developed in consideration of the above-mentioned conventional problems.A convex engaging body is provided protruding from the center of the bottom of the coupler, and L-shaped pieces are provided on both sides of the bottom to engage a pair of opposing locks. A cylindrical body is provided on the back surface of the lamp housing, and the cylindrical body is provided with a pair of flanges that engage with the respective engagement grooves of the coupler and a standing wall that engages with the engaging body of the coupler. The problems of the prior art are solved by providing a guide body having a pair of ribs at its tip that are located near the cylindrical body and support the rear end of the coupler attached to the cylindrical body.

[Effect]

In the present invention, the coupler mounting portion can be formed without recessing the lamp housing, and even when a reflective surface is formed on the inner surface of the lamp housing, no recess is formed on the reflective surface side.

〔Example〕

Next, the present invention will be explained in detail based on an embodiment shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a resin coupler provided at the end of a power supply cord to a lamp, etc. On the back side of the coupler 1, L-shaped pieces 10 are provided on both the left and right sides, as shown in Figure 1. Opposite locking grooves 2 are formed. Further, a convex engaging body 3 whose surface is inclined toward the coupler insertion direction is integrally protruded from the center between the locking grooves 2 .

4 in the figure is a coupler attachment part provided on the back surface of the lamp housing, and the coupler attachment part 4 consists of a cylindrical body 5 and a guide body 6 that protrude rearward (upwards in the drawing) from the lamp housing. It is something. As shown in FIG. 1, a pair of flanges 50 are provided on both sides of the upper end of the cylindrical body 5, facing laterally and corresponding to the locking grooves of the coupler. A standing wall 51 on which the engaging body 3 of the coupler 1 is engaged is provided at the rear.
Further, the guide body 6 is located near the cylinder body 5,
The guide body 6 and the cylindrical body 5 are arranged side by side along the coupler insertion direction, and a pair of ribs 60 are integrally provided at the tip of the guide body 6 so that the rear end of the coupler is positioned. They are separated by the width dimension.

When attaching the coupler 1 to the coupler attachment part 4, insert the flanges 50 into each of the locking grooves 2 of the coupler 1, slide the coupler until it abuts the rear end 20 of the locking groove 2, and insert the coupler into the cylindrical body 5. The above-mentioned engaging body 3 may be attached to the vertical wall 51 of the cylindrical body 5 once.
After that, it is latched onto the upper end of the standing wall 51 and fixed without moving back and forth in the insertion direction. Furthermore, when sliding the coupler,
The coupler is positioned between the ribs 60 and guided toward the cylindrical body 5, and even when inserted into the cylindrical body 5, the rear end of the coupler is positioned and supported without moving in the left-right direction.

[Effect of idea]

As explained above, according to the present invention, the engagement body is provided on the back surface of the coupler, and the back surface of the lamp housing is provided with a collar that engages with the engagement groove of the coupler and a standing wall that engages with the engagement body. A cylindrical body is provided facing rearward from the lamp housing, and a guide body having a pair of ribs that guides the coupler toward the cylindrical body and prevents the rear end from moving is also provided rearward from the lamp housing. This eliminates the need to provide a hole in the lamp housing that corresponds to the engaging body of the coupler, and no recess is formed on the inner surface of the lamp housing due to the coupler mounting portion, and the inner surface corresponding to the coupler mounting portion is It can be formed into a curved surface that is continuous with the surface of the part. Even if a reflective surface is formed on the inner surface of the lamp housing, the effective reflective surface will not be reduced, and the visibility when the lamp is lit will not deteriorate, resulting in excellent practical effects. .
