Description

[Detailed explanation of the idea] The present invention relates to a headlight for a motorcycle.

As shown in FIGS. 1 and 2, a conventional headlight case 2 made of synthetic resin is attached to the front fork via bolts 7 through openings provided in headlight mounting bosses 8 provided on both left and right sides. The headlight case 2 houses a wire harness 10 for connecting various electrical components and a coupler 6. It consists of a coupler half body 6b that houses the female terminal, and they are pulled apart by placing a finger on the end 6C of the coupler half body 6a and the flange 6d of the coupler half body 6b and removing the claw 6f of the engaging part 6e. It has become.

These wire harnesses and couplers are connected and installed inside the headlight case, but there is limited space inside the headlight case, so if you do not store the wire harness and coupler efficiently, it will be difficult to install the headlight body. This causes the inconvenience of being difficult.

By the way, if the above-mentioned coupler is positioned and fixed inside the headlight case, the wire harness can be made as short as possible, and the coupler can be stored more efficiently. In order to fix it, it is desirable to form a recess in the inner wall surface of the headlight case, and to fit a part of the coupler mounting bracket or the flange of the coupler into the recess, or to fix it with bolts or the like after fitting.

It is convenient to form the recessed portion in the inner wall surface when the headlight case is molded using a synthetic resin, but forming the recessed portion using a mold poses a problem of mold cutting.

Therefore, when forming four or more recesses on the inner wall surface of the headlight case during molding, the present invention arranges the recesses so that they do not become an obstacle to the mold-cutting process, and the shape of the recesses is adjusted so that they do not become an obstacle to the mold-cutting process. The challenge is to create a shape that does not.

The measures taken to solve this problem are as follows.

(1) A pair of left and right bosses are provided protruding from the bottom center of the bottom of the headlight case.2) A recess is formed on the inner end surface of the boss of the headlight mounting boss, and this recess is also placed on the front side of the headlight case. (3) Forming a recessed portion opening on both upper and lower sides in the inner end surface of the boss protruding from the center of the lower part of the bottom surface of the headlight case, and forming grooves on both left and right side surfaces of the recessed portion.

The above means works as follows.

In other words, the mounting bosses of the four couplers are formed symmetrically on the headlight mounting part and the bottom, respectively, and the recesses provided in these bosses all open toward the front (large diameter part) of the headlight case. , the die cutting direction and its opening direction match.

Therefore, by pulling out the female mold toward the front side of the headlight case, the convex portion of the female mold for forming the recessed portion can be pulled out from the recessed portion without any trouble.

In addition, the bosses are arranged symmetrically and in a dispersed manner inside the headlight case, so when removing the female protrusion from the concave part of each boss during die cutting, there is no need to force the headlight case locally. No force acts on it.

Next, this means will be explained in more detail with reference to the drawings.

Recesses 8a, 8a are formed in the headlight mounting bosses 8, 8 protruding from the inner end surfaces of the left and right sides of the bowl-shaped headlight case 2 made of synthetic resin. It opens toward the front (large diameter part).

Further, bosses 5, 5 are symmetrically provided on the bottom 2a of the headlight case 2, and vertically penetrate through the inner end surface of the boss 5.
In addition, a recessed portion 5a opening toward the front surface of the headlight case 2 is formed, and a groove 5b is formed on the inner surface of this recessed portion 5a.

Note that the groove 5b may optionally be made to match the desired mounting direction of the coupler.

Four couplers are attached to this headlight case 2 as follows.

First, a coupler support piece 9 made of a metal strip is provided in the upper recessed portion 8a and is fastened with a tightening bolt 7, and the support piece 9 holds both sides of the coupler 6 with elastic tongue pieces 9a.

Further, a flange 6d of the coupler 6 is supported by the lower recessed portion 5a by being fitted into the groove 5a.

In addition, 3 and 4 in the figure indicate insertion holes for inserting harnesses such as wire harnesses and couplers from various electrical components.

In this way, according to the present invention, the boss for supporting the coupler of the harness to be stored in the inner space of the bowl-shaped headlight case made of synthetic resin is recessed so as not to hinder the mold cutting after the headlight case is molded. Since the entry part is integrally shaped, there is no need to separately provide a support member for the coupler, and the coupler can be easily and reliably fixed.

Additionally, since the coupler support is positioned within the headlight case, the length of the wire harness can be made shorter than before, making storage more efficient.

Furthermore, since the conventional mounting parts can be used for the headlight mounting bosses on both the left and right sides of the headlight case, there is no need to form new bosses. This has the effect of reinforcing the area around the insertion hole for harnesses that opens at the bottom of the case.
