Description

[Detailed description of the invention] The present invention relates to a volume mounting device in which a plurality of volumes are arranged side by side on a printed circuit board, the volume is housed in a cabinet, and a plurality of knobs protruding from the cabinet can be rotated. The purpose of this is to improve the operability of the knobs.

Generally, when installing a volume on a printed circuit board, the first
As shown in the figure and FIG. 2, the volume main body 3 is made to correspond to the recess 2 of the printed circuit board 1, and its mounting legs 3a are inserted into the mounting holes of the printed circuit board 1 and soldered.
b was electrically connected to the printed circuit board 1.

However, when using the volume 3 with the above-mentioned mounting legs 3a, the instability of the support of the mounting legs 3a causes variations in the individual mounting conditions. When attached, the knob 4 was also attached at an angle.

Therefore, if this is housed in a cabinet and the knob 4 is made to protrude beyond the operation window arranged in parallel in the cabinet, the knob 4 will come into contact with the wall of the operation window, so that the knob itself cannot be operated. This had the disadvantage of significantly deteriorating performance and operational feel.

The present invention eliminates these conventional drawbacks,
Hereinafter, the present invention will be explained with reference to drawings of embodiments.

3 to 8 show an embodiment of the volume mounting device of the present invention, in which 11 is a printed circuit board, 12 is a volume main body to which a lead-out terminal 12a is electrically connected to the printed circuit board 11; Reference numeral 13 denotes a knob attached to the operating shaft 12b of the volume main body 12 with a screw 14.

Here, the volume main body 12 is connected to the printed circuit board 11.
At one end, a plurality of them are arranged in a line.

15 is a printed circuit board 1 on which the volume main body 12 is attached.
1 is fixed, and a plurality of sets of arc-shaped guide pieces 16 a , 16 b are provided at one end thereof facing each other, and the guide pieces 16 a , 16
A protrusion 17 is provided at the center of b.

Here, the guide pieces 16a, 16b and the protrusion 17 are 1
As a set, a plurality of them are arranged in parallel so as to correspond to the volume body 12 attached to the printed circuit board 11, respectively.

Reference numeral 18 denotes the cabinet body, in which the chassis structure 15 and the printed circuit board 11 are connected to screws 19 and 22.
It is installed with this.

Reference numeral 20 denotes a cabinet lid body that is integrated with the cabinet body 18, and a plurality of operation windows 23 for the knobs 13 are arranged in parallel on its top plate 20a.

Further, on the inner surface of the front plate 20b of the cabinet lid body 20, arc-shaped guide pieces 21a, 21 are arranged opposite to each other.
A plurality of sets of the knobs b are arranged in parallel so as to face the knob 20.

In this way, the volume body 12 is attached to one end of the printed circuit board 11.
A plurality of sets of guide pieces 16 a and 16 b of the knob 13 attached to the volume body 12 are arranged in parallel on the chassis structure 15 on which the printed circuit board is supported, and the guide pieces 16 a and 16 b are arranged in parallel. If the knob 13 of the volume main body 12 is configured to guide the knob 13, the volume main body 12 can be attached to the printed circuit board 11 simply by holding its leading terminal 12a.

Then, a knob 1 attached to the volume body 12 is provided.
3 are guide pieces 16a, 16b and 21a, 21b
Even if the horizontal attachment angle of the volume main body 12 to the printed circuit board 11 varies slightly due to the relationship in which the volume main body 12 is supported by the above-described structure, the lead-out terminal 12a has flexibility and can absorb this variation.

In the above embodiment, guide pieces 16 a and 16 b are provided on the chassis structure 15 and the cabinet lid body 20, respectively.
, 21 a and 21 b were provided, but Fig. 9 and Fig. 1
As shown in FIG. 0, the guide piece 17a of the chassis structure 15.

If a mechanism for maintaining the horizontal mounting state of the volume body 12 is added to 17b, the guide pieces 21a and 21b are not necessarily required for the cabinet lid body 20.

As described above, according to the present invention, a plurality of volume bodies are arranged side by side at one end of a printed circuit board, and a substantially ring-shaped volume body is installed in a chassis structure in which the printed circuit board is supported to horizontally support the mounted state of the volume body. Since we have provided a guide piece,
The volume main body can be attached to the printed circuit board using only lead-out terminals, improving the installation workability.

Moreover, even if the mounting angle of the volume main body to the printed circuit board by the lead-out terminal varies slightly, since the lead-out terminal has spring properties, the mounting angle of the volume main body to the printed circuit board can be corrected using the guide piece. Can be done.

Therefore, when the chassis structure and the printed circuit board are installed in the cabinet, there will be no problem such as the knob attached to the volume body coming into contact with the cabinet's operation window and impairing its operability and feeling. Its practical value is extremely great.
