At the same time, insert the anti-rotation protrusion 1b into the anti-rotation hole 2b, attach the washer 3, and tighten with the nut 4 to fix it.

However, the device shown in FIG. 1 has the following drawbacks.

That is, if the space into which the volume body 1 can fit is very small, it may be impossible or very difficult to insert the volume body 1 from the back side of the panel 2 through the shaft 1c.

In order to eliminate the above-mentioned drawbacks, the present invention provides a hole large enough to allow electrical components to pass through the mounting plate, as well as a plurality of notches around the periphery of this hole, allowing the electrical components to pass through the hole and connect to the back side of the mounting plate. By clamping the mounting plate from both sides of the surface and mounting the electrical component on the mounting plate, we provide a mounting structure for electrical components that allows electrical components to be easily mounted from the front on a mounting plate that has no depth for mounting. The purpose is to

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 2 shows an embodiment of the present invention.

In FIG. 2, the same reference numerals as in FIG. 1 indicate the same parts.

6 is a circular mounting hole provided in the mounting panel 5, 7a, 7b,
Reference numeral 7c denotes penetrating notches provided radially at mutual angles of 120 on the circumferential line of the mounting hole 6, and 8a, 8b, and 8c indicate penetrating notches 7a, 7b, and 7c of the mounting hole 6 at an angle of 60 from each of the penetrating notches 7a, 7b, and 7c. It is a non-penetrating recessed part that forms a positioning part provided on the periphery.

9 is a radial backside protrusion 9a on the circumference at an angle of 120;
The width and length of each rear projection 9at9bt9c are the same as the notches 7a and 7b.
, 7c, and when the rear protrusions 9a, 9b, and 9C are aligned with the notches 7a, 7b, and 7c above the mounting hole 6, it is parallel to the panel surface.
The back side washer 9 can pass through the mounting hole 6.

On the housing, 9d is a protrusion 1b for preventing rotation of the volume body 1.
This is a notch forming a rotation stopper provided on the back side washer 9 to be engaged with, thereby preventing the volume body 1 and the back side washer 9 from rotating relative to each other.

Reference numeral 10 denotes a back washer 90, and a front washer that is attached to the cylindrical threaded portion 1a of the volume body 1. Also, there are front side protrusions 10a and 10b which form surface contact portions at an angle of 120.
.
, 8c is bent into a crank shape with a dimension that is less than the plate thickness.

When the protrusions 10a, 10b, 10c are aligned with the recesses 8a, 8b, 8c of the mounting hole 6, they can penetrate into the panel surface by the depth of the recesses 8a, 8b, 8c.

Dimension 10d is a protrusion 1b for preventing rotation of the volume body 1.
This is a notch forming a rotation stopper provided on the front washer 10 to be engaged with.

Here, if two washers are inserted into the cylindrical threaded portion 1a of the volume body 1 in the order shown in FIG.
, 100 each protrusion 9a to 9c, 10a10c is 3 on the circumference
Each cutout 9d, 1
The position 0d is shifted by 30 between the two washers 9 and 10.

Next, to explain how to install the above configuration, insert the washers 9 and 10 into the cylindrical screw portion 1a of the volume body 1 in the order described above, and engage the anti-rotation projections 1b into the notches 9d and 10d. Fit them together and temporarily tighten them with nut 4, making sure there is no looseness.

Next, attach the volume body 1 to the mounting hole 6 from the front side of the panel 1.
Align the notches 7a, 7bs7c of the mounting hole 6 with the protrusions 9a, 9b, 9c of the back side washer 9, push the protrusions 9a, 9b, 9c into the back side 1 of the panel 5, and then remove the shirt. Hold it and rotate it 30 times to the right so that the protrusions 10a, 10b, 10c of the front washer 10 are depressed into the recesses 8a, 8b, 8c of the mounting hole 6, and then fully tighten the nut 4.

As a result, each protrusion 9a, 9b, 9 of the back side washer 9
c faces the back surface of the panel 5, and each of the protrusions 9a, 9b,
9c and each protrusion 10a, 10b, 10 of the front washer 10
The volume body 1 is fixed to the panel 5 by sandwiching the panel 5 between the panel 5 and the panel 5.

Other embodiments of the present invention are shown in FIGS. 3 to 6.

3a and 3b are each washer 9 in FIG. 2,
Corresponding to No. 10, the notch 9d is for rotation prevention.

10d is a case where the protrusions 9a to 9C and 10a' to 10c' of both washers 9 and 10 are overlapped, and the protrusions 10a' to 10d are overlapped to the protrusions 9a to 9c.
0c' is made wide, and each notch 7 in Fig. 2
a to 7c pass through the protrusions 9a to 9cl/i in FIG. 3a, but not to the protrusions 10a' to 10c' in FIG.

FIG. 4 shows an integrated version of the washers 9 and 10 in FIG.
11b are inserted into the grooves 12a and 12b provided in the washer 10, and the tips of the cut and raised portions 11a and 11b are bent to a certain extent and integrated.

When manufacturing a product, if you make what is shown in Fig. 4 in the previous process, there will be fewer mistakes when assembling the washer when installing the volume body 1. Fig. 5 shows the back washer 9 in Fig. 2. Instead, the back side protrusions 9a to 9c are provided integrally with the volume main body 1, and if this is combined with the front side washer 10, the same effect as shown in FIG. 2 can be obtained.

This embodiment is effective when manufacturing a dedicated volume.

FIG. 6 shows an example where the thickness of the panel 5 is so thin that it is difficult to provide the recesses 8a to 8c of the mounting holes 6 in FIG.
A rotation preventing portion made of =13c is provided.

In this case, instead of the front washer 10 in FIG.
It is sufficient to set the front washer with the protrusion facing the panel side.

In all of the above examples, there were three washer protrusions, but it is also possible to use two or four or more protrusions.

Further, the washer 10 in FIG. 2 and the outer washers 10 of other examples all have protrusions 10a10c and 10a'.
~10c' is provided, but if the instability of the rotational position during installation is allowed, use a shape that does not pass through the mounting hole 6, for example, a front washer of a size that allows the mounting hole 6 to be removed. etc., it is not necessary to provide any particular protrusion on the front washer.

In this case, the portion that protrudes from the mounting hole 6 and contacts the surface of the panel 5 becomes the surface contact portion.

In such a case, it is possible to fix the position by providing a protrusion on one side, or it is also possible to fix the position by hooking the protrusion on the washer 9 side to the panel from inside the panel.

In the example described above, the mounted part was a volume, but a rotary switch or other electrical parts can be mounted in the same way.

As described above, in the present invention, a mounting hole large enough to allow the electrical component to pass through is provided in the mounting plate, and a plurality of notches are provided radially from the mounting hole on the periphery of the mounting hole, and each of the notches It has a rear protrusion that rotates with the main body of the electrical component and faces the back surface of the mounting plate when the main body of the electrical component is rotated. A front washer having a rotation stopper that engages with the protrusion is fitted onto the outer periphery of the cylindrical threaded part of the electrical component, and a nut is screwed into the cylindrical threaded part of the electrical component body through the front washer. Since the mounting plate is held between the contact part and the electrical components are mounted on the mounting plate, it is possible to easily mount the electrical components from the front on the mounting plate, which has no depth for mounting.
In addition, by temporarily tightening washers to the existing cylindrical threads of electrical components, it is possible to not only handle all components as one unit when installing electrical components, but also to utilize the protrusions to prevent rotation of electrical components. This is an advantage in that the front washer can be mounted to the electrical component body to prevent it from rotating at any time, and the electrical component can be mounted to the mounting plate with a simple configuration without using separate mounting bolts. It has a positive effect.
