Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a mounting structure for attaching an automobile coupler for electrical connection to a component such as a vehicle lamp. The present invention relates to the automobile coupler provided with a shoe portion.

<<Prior Art>> FIG. 3 shows a conventional mounting structure of this type of automobile coupler 10, which corresponds to the height H of the channel-shaped portion of the shoe portion 10a provided in the automobile coupler 10. A plate-like member made of metal or the like having a thickness of approximately the same size as the width W of the shoe portion 10a is used as the support fitting 21, and the support fitting 21 is
a locking protrusion 10b protruding from the shoe portion 11a;
A locking hole 21a is provided for locking to the shoe part 10a during installation.
Attachment is completed by inserting it in a press-fit state until the locking protrusion 10b and the locking hole 21a fit together. It goes without saying that the other end of the support fitting 21 has a shape suitable for mounting the automobile coupler 10 thereon.

<<Problems to be solved by the invention>> However, in the conventional mounting structure described above, as shown in an enlarged view in FIG.
Although the insertion force is reduced by tilting 0b in the insertion direction, the thickness of the mounting bracket 21 is inevitably determined by the height H of the shoe part 10a, which makes it thick and difficult to deform. The problem is that a large insertion force is required and the work is difficult, and for the above-mentioned reasons, excessive stress is applied to the locking protrusion 10b during insertion and it is scraped off, making it impossible to obtain sufficient holding force after installation. This caused a practical problem.

<Means for Solving the Problems> As a specific means for solving the problems that occur in the conventional structure described above, the present invention has a channel-shaped shoe portion provided with a locking protrusion, and the locking projection has a channel-shaped shoe portion. In the mounting structure for an automobile coupler in which a plate-shaped support metal fitting provided with a locking hole for locking to a locking protrusion is inserted into the shoe part, the support metal fitting is formed of a thin plate with a rising part on the peripheral edge. A mounting structure for a coupler for an automobile, characterized in that a protruding portion is provided at the front in the insertion direction of the locking hole to gradually reduce the amount of protrusion from the locking protrusion of the shoe portion as the shoe portion is inserted. By providing this, the above-mentioned conventional problems are solved by reducing the insertion force and also eliminating the possibility of the engaging protrusion being scraped off, thereby ensuring reliable retention.

<<Example>> Next, the present invention will be described in detail based on an example shown in the drawings.

In order to facilitate understanding, parts that are the same as those in the conventional example will be described with the same reference numerals, and descriptions of some overlapping parts will be omitted.

What is indicated by the reference numeral 1 in FIG. 1 is a support fitting according to the present invention, and this support fitting 1 is formed of a plate-like member made of metal or the like similar to the conventional example, and is used as a coupler 10 for an automobile. Similarly, the locking hole 1a that fits into and locks the locking protrusion 10b provided on the shoe part 10a is provided, but the plate thickness of this member is greater than the height H of the shoe part 10a. It is made thin and has a rising portion 1b on the periphery to meet the height H mentioned above.

Further, a protrusion 1c is provided in front of the attachment hole 1a of the support fitting 1 in the insertion direction.

What is shown in FIG. 2 shows the protrusion 1c in more detail in relation to the engagement protrusion 10b, and the protrusion 1c is shown in more detail in relation to the engagement protrusion 10b, from higher than the engagement protrusion 10b to none according to the insertion direction indicated by arrow S in the figure. The protruding portion 1c is formed such that the amount of protrusion gradually decreases until it becomes .

By forming the support fitting 1 in this manner, when the automobile coupler 10 is installed, the protruding portion 1c does not come into contact with the engaging protrusion 10b at the beginning of insertion, and gradually increases as the insertion progresses. The contact pressure increases as the pressure increases. Here, since the supporting metal fitting 1 of the present invention is formed thinner than that of the conventional example, deformation easily occurs due to the pressure of the abutment described above, and this pressure is absorbed by deformation,
This reduces the sudden increase in insertion force and prevents the engagement protrusion 10b from being scraped off.

Incidentally, problems such as mounting looseness and reduced strength that may occur due to the support metal fitting 1 having a thickness thinner than the height H of the shoe portion 1a can be solved by the rising portion 1b acting as a reinforcing rib. However, this will be supplemented.

<<Effect of the invention>> As explained above, according to the invention, the supporting metal fitting is formed of a thin plate with a rising part, and the protruding part whose height gradually decreases as it is inserted is placed in front of the insertion direction of the locking hole. By providing this, during the installation work, it is easy to deform when it comes into contact with the shoe part locking protrusion of the support metal fitting, relieves the contact pressure, eliminates the extremely large insertion force, and improves work efficiency. In addition, due to the above-mentioned relaxation of the contact pressure, the locking protrusion is prevented from being scraped off, and the holding performance after installation is completed is ensured, resulting in an excellent effect of improving reliability. It is something to play.
