Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal exterior part such as a panel, a door, and a decorating machine, which is made by extruding aluminum or the like, and has buttons at various positions at various positions on its back surface. The present invention relates to a member coupling device capable of directly fixing another member such as.

2. Description of the Related Art In recent years, audio equipment such as amplifiers and tuners has been diversified. Along with that, it has become necessary to support various designs in a short period of time.

For that purpose, it is necessary to provide an exterior member joining device that simplifies the parts and requires a small amount of mold investment and a small mold manufacturing schedule.

Hereinafter, a conventional exterior member coupling device will be described with reference to FIG.

In FIG. 5, 1 is a panel, and an undercut portion
It has 1a and 1b. Reference numeral 2 is a grill having claws 2a and 2b and a boss 2c. 3 is a button, 4 is a printed circuit board, 5
Is a tact switch attached to the printed wiring board,
6 is a screw.

In the above structure, the claws 2a, 2b of the grill 2 are fitted into the undercut portions 1a, 1b of the panel 1 to join the grill 2 and the panel 1. The structure is such that members such as the button 3 and the printed wiring board 4 are fixed to the boss 2c of the combined grill with screws 6.

Problems to be Solved by the Invention However, in the above-mentioned conventional example, a large member such as the grill 2 is necessary for the boss 2c necessary for fixing the button 3 and the printed wiring board 4, and therefore a large mold,
A large amount of material was required, which led to an increase in material cost and die manufacturing schedule.

It is also possible to form holes in the ribs on the back surface of the aluminum panel and fix the members directly, but there is the drawback that the mounting height cannot be changed on the same line.

In view of the above problems, the present invention directly on the back surface of a metal exterior component such as a panel using an extrusion process of aluminum or the like,
(EN) Provided is an exterior member joining device capable of integrally molding a necessary small molded article such as a boss and greatly reducing the material cost and the die manufacturing schedule.

Means for Solving the Problems In order to solve the above problems, the exterior member coupling device of the present invention is connected to the back surface of a metal exterior component such as a panel using an extruded material such as aluminum in the extrusion direction during extrusion. A rib is formed and formed during the extrusion process, or an undercut portion is provided on the rib by pressing or cutting after the extrusion process, and a part of the rib is left by pressing or cutting, and the periphery of the remaining rib It is a plastic boss that is integrally molded.

Effect The present invention has the above-described configuration, by directly molding a small plastic required for a boss or the like directly on the back surface of an aluminum extruded panel to reduce the material and size of the mold, thereby reducing the material cost and the mold manufacturing schedule. It is possible to significantly reduce the.

Examples Hereinafter, an exterior member coupling device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of an exterior member coupling device according to an embodiment of the present invention.

The same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

1d is the remaining rib necessary for mounting the boss on the back surface of the aluminum extruded panel 1 formed by extrusion molding of aluminum and removing a part of the rib formed during extrusion processing by post-processing, and 1e is the rib 1d It is a plastic boss that is integrally molded by fitting an aluminum panel around it into a plastic molding machine.

FIG. 2 is a perspective view of a boss portion integrally molded with an aluminum extruded panel. 1g is a part of the rib 1d having an undercut formed when the panel 1 is extruded and removed by partial pressing or cutting.

FIG. 3 shows a second embodiment in which the undercut portion is not formed on the rib when the aluminum extruded panel 1 is extruded, and the undercut portion 1h is formed by post-processing by pressing or cutting.
It is an example of forming.

FIG. 4 shows a sectional view of the integrally molded boss. In order to increase the strength of the root of the rib 1d of the aluminum panel 1, the R or C surface 1i may be formed.

With the above configuration, it is possible to integrally mold a plastic boss having a tensile strength, a torsion strength, etc., which is sufficient to fix and support another member, on the back surface of the aluminum panel.

EFFECTS OF THE INVENTION As described above, according to the exterior member coupling device of the present invention, a large plastic part such as a grill is not required, and the material cost and the die manufacturing schedule are significantly reduced, and the practical value is large. is there.
