Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to the structure of a holder used in an audio device.

(B) Problems to be Solved by Conventional Techniques and Inventions Conventionally, as a structure of a holder for fixing a component such as a printed circuit board to a chassis or a housing via a holder, for example, as shown in FIG. The one shown in FIG. 5 is known.

Numerals 20 and 21 in FIGS. 4 and 5 denote holders formed by cutting and raising the chassis 22, and by mounting the printed circuit board 23 on the mounting surface 20a of the holder 20 and the mounting surface 21a of the holder 21, the printed circuit board 23 I was trying to get the earth.

However, the above-mentioned conventional one has a drawback that the vibration of the chassis 22 is transmitted to the components on the printed circuit board 23 via the holder 20 or 21, so that the vibration deteriorates the reproduced sound quality of the audio device.

Further, since the holder 20 or 21 is cut and raised in the chassis 22, holes 24 or 25 are formed, and this hole has a drawback that it becomes an obstacle in obtaining the safety standard of each country.

The present invention has been made in view of the above points, and its purpose is not to interfere with the acquisition of safety standards.
Another object of the present invention is to provide a holder structure that does not deteriorate the reproduction sound quality of an audio device.

(C) Means for Solving the Problem The structure of the holder of the present invention is such that the holder main body made of resin and the holder main body made of resin are fixed to the chassis and the housing via the holder. A metal conductor having a substantially U-shaped cross section is provided to electrically connect a first surface of the holder, which is in contact with the chassis or the housing, and a second surface for fixing a component such as the first printed circuit board. The conductor is press-fitted into the holder, and a third surface for fixing components such as the second printed circuit board is provided.

(D) Operation According to the present invention, in the holder in which parts such as a printed circuit board are fixed to the chassis or the housing via the holder, the holder main body made of resin is brought into contact with the chassis or the housing of the holder. A metal conductor having a substantially U-shaped cross section for electrically conducting the first surface and a second surface for fixing a component such as a printed circuit board is provided, and the metal conductor is press-fitted into the holder main body, and the second Since the third surface for fixing components such as the printed circuit board is provided, the holder has a flexible structure, so that the vibration of the chassis and the housing is damped.

Therefore, the reproduced sound quality of the audio device is not adversely affected. In addition, it is possible to reliably ground the attached parts.

(E) Embodiment An embodiment of the structure of the holder according to the present invention is shown in FIGS.
A description will be given based on the figure.

FIG. 1 is an exploded perspective view, FIG. 2 is a perspective view of a holder, and FIG. 3 is a side sectional view showing a state where a printed circuit board on a chassis is fixed by the holder.

In the figure, 1 is a holder, and this holder 1 is composed of a holder main body (hereinafter referred to as main body) 2 made of resin and a metal conductor 3 having a substantially U-shaped cross section.

The main body 2 is provided with a convex portion 4 for positioning the holder 1 on a chassis or a casing and a fixing hook 5.

Further, since the metal conductor having a substantially U-shaped cross section is press-fitted and fixed to the main body 2 so as to sandwich the main body 2, the holder 1
The first surface 6 that is in contact with the chassis or the housing is electrically connected to the second surface 7 that fixes components such as the first printed circuit board.

In the holder structure thus configured, the chassis 8
The holder 1 is mounted on the upper side, and the first surface 6 of the holder 1 is further attached.
If the printed circuit board 9 is fixed to the mounting hole 6a formed by the screw 10 with the screw 10, the printed circuit board 9 is fixed on the chassis 8 and the ground pattern of the printed circuit board 9 is grounded to the chassis 8 via the metal conductor 3. .

If the metal conductor 3 is provided with a projection (dough), the projection bites into the first surface 6 and the second surface 7 of the main body 2, and therefore the metal conductor 3 does not separate from the main body 2.

In this embodiment, in order to fix the holder 1 more reliably, the chassis 8 is screwed with the screws 11.

In addition, the holder 1 has a surface 12 having a step with the second surface 6.
Is provided, and components such as the second printed circuit board can be fixed to the surface 12.

As described above, the structure of the holder of the present invention is such that the holder main body made of resin and the chassis or housing of the holder are fixed to the chassis and the housing through which the parts such as the printed circuit board are fixed. A metal conductor having a substantially U-shaped cross section for electrically conducting a first surface in contact with the second surface for fixing a component such as a printed circuit board, and the metal conductor is press-fitted into the holder body. is there.

(F) Effect of the Invention According to the structure of the holder according to the present invention, since it is configured as described above, since the holder has the flexible structure, the vibration of the chassis and the housing is attenuated.

Therefore, the reproduced sound quality of the audio device is not adversely affected.

In addition, it is possible to reliably ground the attached parts.

Two PCBs can be fixed depending on the shape of the holder.

In addition, it has excellent features such as a simple structure and a low cost, which makes it easy to implement.
