Description

[Detailed Description of the Invention] This invention relates to an operation knob mounting structure for an electronic device that operates a switch or the like by operating an operation knob including an operation button installed on a front panel of the electronic device.

Conventionally, the operation knob mounting structure used for electronic devices is configured such that the operation knob including the operation button protruding from the front panel operates the connected switch etc. by sliding the operation knob. ing.

In this case, the front panel or the chassis placed at the rear of the front panel is provided with a guide hole into which the operation knob is inserted.The guide hole and the operation knob have similar shapes, and are generally rectangular or square. Although it is made in cross section, when installing this type of operation knob to a switch, etc., the operator needs to be careful about the installation direction and angle, etc.
If this is not done, problems such as the front panel not being able to be inserted into the protruding operating knob during assembly will occur, resulting in extremely difficult work.

This invention was made in order to eliminate the above-mentioned conventional drawbacks, and the combination of the operating knob and the guide hole into which the operating knob is fitted is limited to one direction, thereby preventing incorrect insertion. There is a knob that can be operated to provide a mounting structure.

Hereinafter, embodiments of the operation knob mounting structure of this invention will be described based on the drawings.

1 and 2 are a front view and a side view, respectively, of the operation knob mounting structure in one embodiment. When viewed from the side, the operation knob 1 is connected to the switch 3.
A connecting portion 1B connected to the chassis and a pressing portion 1A pressed by an operation button protruding from the chassis or the like are shaped at different levels. Also, when viewed from the front, the guide hole 2 formed in the chassis 2 of the electronic device has a cross-sectional shape with different widths at the top and bottom.
1 and is configured to be slidable.
The chassis 2 of the electronic device is configured to have a shape that follows the cross-sectional shape of the operating knob 1, and as shown in the figure, a pair of upper and lower regulation grooves are provided, and each regulation groove has a different shape. .

In this way, for example, by configuring the operating knob and guide hole to have a cross-sectional shape that is vertically or horizontally asymmetrical, such as having different widths at the top and bottom, and in which the pressing part and the connecting part are at different levels, this can be achieved. Since the operation knob is only mounted in one direction, the operation knob 1, guide hole 21, and switch 3 can be assembled very easily.

Figures 3a to 3f show the operation knob 1 and guide hole 2.
This is another example showing the shape of the operation knob 1, and even if the vertical width of the operation knob 1 is the same, the same effect can be obtained even if one of the shapes is partially changed.

Although the above-mentioned operation knob is shown as being connected to the chassis, the same applies to the front panel, and the operation knob may be installed to the front panel.

As explained above, the operating knob mounting structure of the electronic device of this invention is provided in the chassis or panel of the electronic device, and is fitted into a guide hole having a vertically or horizontally asymmetrical shape and having a similar shape to the guide hole. Since the connecting part connected to the switch and the pressing part protruding from the chassis and the like are pressed by an operating button, the operating knob has a different shape. It is possible to prevent installation errors, improve workability, and contribute to uniform finishing.
