Abstract

PROBLEM TO BE SOLVED: To reduce a work cost and to control the cost of equipment for a witch operating device by a simple attaching work instead of a thermal fusing work, and to improve a product quality by reducing a variations in work. SOLUTION: When an elastic plate 10 for controlling a position is disposed in a button 7, and a bottom plate 3 holding a PWB (a base plate) 2 is screwed to an escutcheon 5, the button 7 is stably fixed by allowing and end surface of the PWB 2 to press the elastic place 10 of the button 7 to the escutcheon 5 side. Only by inserting the button 7 in the escutcheon 5 and screwing the bottom plate 3 from the back without requiring the thermal fusing, the button 7 can be fixed. Accordingly, it is possible to provide a switch operating device produced easily at an inexpensive cost, without few variations in work, with high reliability.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch operating device which is applied to a television receiver, a display monitor, and the like, and which operates a switch from outside using a button.

[0002]

2. Description of the Related Art Conventionally, a switch operating device having the following configuration is generally used.

FIG. 3 is a sectional view showing a conventional switch operating device, in which reference numeral 21 denotes a tact switch, and reference numeral 22 denotes a tact switch 21.
Is fixed to a PWB (substrate), 23 is a bottom plate for holding the PWB 22, 24 is a screw for attaching the PWB 22 to the bottom plate 23, 25 is an escutcheon as an exterior part, 26 is a screw for attaching the bottom plate 23 to the escutcheon 25, and 27 is an escutsion 25 , A button 28 for operating the tact switch 21, and 29 a hinge unit integrally provided with the button 28.

[0004] The button 28 is fixed at one end to a heat welding boss 27 provided on the escutcheon 25 by heat welding, so that the button 28 is exposed outside the escutcheon 25.
By pressing the tip 28, the hinge portion 29 is elastically deformed, and the inner end of the button 28 can operate the tact switch 21.

[0005]

In the conventional switch operating device, when the button 28 is attached to the escutcheon 25, as a method of stably fixing the button 28 without rattling, a part of the button 28 is thermally welded. Therefore, the number of man-hours is increased and equipment during the production process is required, resulting in high cost. In addition, there is a problem in that the operation position of the button 28 is defective due to the unstable position of the button 28 due to variations in the operation of the heat welding.

[0006] In view of the above-mentioned conventional problems, the present invention can achieve a reduction in work cost and equipment investment by simple mounting without using a heat welding method, and an improvement in quality by reducing variations in work. It is an object to provide a switch operating device.

[0007]

In order to achieve the above object, a switch operating device according to the present invention is provided with an elastic plate for position regulation on a button, and the button is mounted on the button by a board on which the switch is mounted via the elastic plate. The button is configured to be stably fixed by being pressed against the exterior component.

As described above, since the button does not require heat welding and is simply pressed and fixed to the exterior component, the switch is inexpensive, has a small work variation, and has high reliability. It becomes an operation device.

[0009]

The invention according to claim 1 of the present invention comprises a board on which a switch is mounted, a fixing member to which the board is fixed, an exterior component to which the fixing member is fixed,
A button provided on the exterior component for operating the switch from the outside is provided, and the button is provided with an elastic plate for elastically contacting the substrate and pressing the button against the exterior component. Since the button is fixed by simply inserting the button into the exterior component and screwing the bottom plate, for example, with a screw, the structure is inexpensive, has less work variation, and the button operation is reliable.

Hereinafter, a preferred embodiment of the present invention will be described.
This will be described with reference to FIGS.

FIG. 1 is a sectional view showing a schematic configuration inside a display monitor for explaining an embodiment of the present invention.
FIG. 2 is an enlarged cross-sectional view of the switch operating device in FIG. 1, 1 is a tact switch, 2 is a PWB (substrate) to which the tact switch 1 is fixed, 3 is a bottom plate as a fixing member for holding the PWB 2, 4 is A screw for fixing the PWB 2 to the bottom plate 3, 5 is an escutcheon as an exterior component, 6 is a screw for fixing the bottom plate 3 to the escutcheon 5, 7 is a button for operating the tact switch 1 from outside, and 8 is a button 7 A button frame 9, which is integrally formed, is provided integrally with the button frame 8, and a hinge portion for moving the button 7 back and forth, and a hinge 10 is provided on the button frame 8, and is received from the end face of the PWB 2. This is an elastic plate that transmits the applied force to the button frame 8. It is conceivable that the elastic plate 10 is integrally molded with the button frame 8 or is provided separately from the button frame 8. In addition, 11 in FIG.
T.

As shown in FIG. 2, the button frame 8 is mounted on the button frame 8 so that the tip of the button 7 projects into the through hole 5a of the escutcheon 5 in FIG.
The bottom plate 3 is fixed to the escutcheon 5 by screws 6 so that the end of the PWB 2 fixed to the bottom plate 3 by screws 4 is elastically contacted with the elastic plate 10 of the button frame 8. Then, the button 7 is sandwiched between the escutcheon 5 and the PWB 2 and further pressed and fixed to the escutcheon 5.

When the button 7 presses the tip of the button 7 exposed to the outside of the escutcheon 5, the hinge 9 is elastically deformed, and the other end of the button 7 can operate the tact switch 1. .

As described above, in the switch operating device according to the present embodiment, each member is fixed with the escutcheon 5 as a position reference, and the tact switch 1 can be stably operated in the forward and backward directions. In addition, it is not necessary to fix a part of the button 7 to the escutcheon 5 by heat welding, and the operation of the button can be performed with high reliability at low cost and with less variation in manufacturing work.

[0015]

As described above, according to the switch operating device of the present invention, there is obtained an advantageous effect that a highly reliable button operation can be obtained at a low operation cost, with a small operation variation.
