Abstract

PURPOSE:To provide an operating mechanism easy to assemble with a simple structure by sliding an operating part by a guide frame, fitting a pressed protruding part into the hole of an operating panel, pressing the pressed protruding part to deflect an integrated spring part, and operating a switch. CONSTITUTION:When the mounting part 11c of a nob switch 11 is inserted along a guide frame 12c, a spring part 11b is deflected by a protruding amount (1) toward the surface side of a pressed protruding part 11a, and the pressed protruding part 11a is fitted to the hole 12a of a holder 12. When the pressed protruding part 11a is pressed, then, a secondary side pushing surface 11d pushes the nob 4a of an electric switch 4 by the deflection of the spring part 11b to operate the electric side switch 4. Thus, the switch operating structure such that the pressed protruding part is integrated with the spring part can facilitate the installation and allow a reduction in cost of the device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a switch operation structure in an electronic device housing or the like.

[Prior Art] A conventional switch operation structure will be explained with reference to FIGS. 3 and 4. FIGS. 3A and 4B are a side view, a plan view, and a cross-sectional view showing the switch operation structure, and in the figures, l is a knob switch, 2 is a holder which is the receiving part of the knob switch l, 3 is a spring that causes the knob switch 1 to slide, and 4 is an electric side switch that has electrical contacts and is mounted on a circuit board 4b on which electronic components and the like are provided.On the outer periphery of the knob switch l, , has a claw piece 1d with a tapered tip, and this claw piece 1d is hooked on the inner step part 2b of the holder 2, and the spring 3
Even if the knob switch 1 is pressed against the surface side of the holder 2, it will not come out.

Next, the operation will be explained. When the operator presses the pressing convex portion 1a of the knob switch l with a finger or the like, the sliding boss 1
c slides along the inner surface of the guide boss 2a of the holder 2, and the secondary side push surface 1b of the knob switch 1 is provided on the same sliding straight line as the center of the knob switch 1. Press knob 4a of No. 4 and switch operation #J (contact O
N or contact 0FF) is completed. For example, this switch operation is when the main power source of the electronic device is turned on or off.

Next, when the operator releases his finger from the knob switch 1.

The knob switch 1 is pushed back by the repulsive force of the spring 3 pressing against the secondary side pressing surface 1b of the knob switch ■.
By sliding the knob switch 1 until the claw ↓d comes into contact with the stepped portion of the inner side 2b of the holder 2, the knob switch 1 returns to the predetermined position before activation.

[Problems to be solved by the invention] Since the conventional switch operation structure is configured as described above, the number of parts is large, and the shape of each part is complicated, resulting in high cost. Since it is necessary to install it on a sliding straight line and the fulcrum cannot be changed, the installation method lacks flexibility, and there are also problems such as complicated assembly due to the large number of parts.

This invention was made to solve the above problems, and has a simple structure and easy installation.

The purpose is to obtain a switch operation structure that can be assembled.

[Means for Solving the Problems] A switch operation structure according to the present invention includes an actuating portion having a pressing protrusion that is in contact with the back surface of an operation panel and that is slidably fitted into a hole of the operation panel. , this actuating part includes a long piece-shaped spring part having the pressing convex part at one end, and a long piece-shaped spring part located on both sides of this spring part, extending substantially parallel to this spring part, and having one end connected to the other end of the spring part. The mounting unit integrated with the holder is composed of a part and a guide frame that holds the operating part in a slidable manner.

[Function] In the switch operation structure according to the present invention, by sliding the actuating portion onto the guide frame, the pressing convex portion faces the hole of the operation panel and is fitted into the hole. When the pressing convex part is pressed, the spring part bends and activates the switch.

[Embodiment] Hereinafter, a switch operation structure which is an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Components that are the same as those in FIGS. 3 and 4 are designated by the same reference numerals, and their explanation will be omitted.

In the figure, (2 is an operation panel 12b having a hole 12a)
The holder 11 is a knob switch as an actuating part having a pressing convex portion 11a that faces the back surface of the operation panel 12b and is slidably fitted into the hole 12a. A long strip-shaped spring portion 11b having a pressing convex portion 11a at one end, and a spring portion 11b located on both sides of this spring portion 11b, extending substantially parallel to this spring portion 11b, and having one end integrated with the other end of the spring portion 11b. The integrated mounting is comprised of a portion 11c. The holder 12 is attached to the knob switch 1 on the back side of the operation panel 12b.
The first installation has two guide frames 12c that hold the part 11c, and the guide frames 12c have a curvilinear cross section and the above-mentioned installation holds the bottom surface n and the outer side surface m of the part 11c in a slidable manner. It is possible.

In the above configuration, the knob switch 11 is installed in part 1.
1c along the guide frames 12c, 12c, and at this time, the amount of protrusion of the pressing convex portion 11a toward the surface side is 1.
The spring portion 11b is bent by the amount, and the hole 12a of the holder 12 is
Attachment is completed when the pressing convex portion 11a is inserted into the holder. When the pressing convex portion 11a is pressed, the spring portion 11
Due to the deflection of b, the secondary side pushing surface lid pushes the knob 4a of the electric side switch 4, and the electric side switch 4 is activated. Further, when the operator releases his finger, the repulsive force of the spring portion 11b causes the pressing convex portion ILa to return to the predetermined position before activation. The amount of protrusion 1 of the pressing convex portion 11a of the knob switch 11 is the same as that of the secondary side pressing surface lid and the knob 4a of the electric side switch 4.
By setting the clearance L1 to be larger than the sum of the switch stroke L2 of the electrical side switch 4, the holder 12 due to the sliding of the knob switch 11 is
It is possible to prevent it from falling off.

Further, the spring portion 11b swings about one end of the spring portion 11b as a fulcrum by pressing the pressing convex portion 11a, and
Since the next side pressing surface 11b slides, it is possible to operate the switch without any problem even if the electric side switch 4 cannot be arranged on the same straight line as the pressing convex portion 11a. That is,
If the position is opposite to the spring portion 11b, the pressing convex portion 1
1 fI′ of a! .

The electrical side switch 4 can be provided regardless of the location.

[Effects of the Invention] As described above, the present invention has an advantage in that the push-button switch operating structure is constructed by integrating the pressing convex portion and the spring portion, so that the installation is easy and the device can be manufactured at a low cost.
