[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a switch structure when a switch button is installed on a member to be attached, and particularly to a switch structure that operates a plurality of switches with one switch button.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in electronic equipment such as audio equipment, a switch structure of a type in which a single switch button operates a plurality of switches has been widely used due to downsizing of the equipment. Such a switch, for example, what is generally called a double function switch, has two switches arranged on the back side of one switch button and mounted so that the switch button oscillates. The switch is configured to be operated.

[0003]

[Problems to be solved by the device]

 In the conventional switch structure of this type, the structure for holding the switch button in the equilibrium state and returning to the original state after the pressing operation is complicated, and therefore the spring, sponge, rubber, etc. There was a drawback that required special parts of. It is also possible to realize a double function with a slide switch, but in general, the structure of the push switch and the slide switch are completely different, so if you try to change the push or slide operation method, not only the switch button but also the printed circuit board It was necessary to change the shape of the upper switch and the attached member such as the front panel, and it was difficult to standardize the switch structure between both types.

However, even an operation switch having the same function can give a completely different feeling to a push switch and a slide switch, and because of a simple product design change due to a change in the switch button operation method, it is possible to switch between both methods. There is a strong demand to standardize the switch structure. In terms of operability, it is important to be able to easily change the switch button operating method.

It is an object of the present invention to provide a simple switch structure, and yet to easily select a switch operating method.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention attaches a switch button to an opening formed in a member to be attached, and operates a plurality of switches individually arranged on the back side of the member to be attached by operating the switch button. In the switch structure, a plurality of elastic switch operating pieces are integrally formed with the attached member in the opening of the attached member, and the switch operating pieces are individually provided on the back surface of the switch button. It is characterized in that it is provided with a raised portion having an inclined surface that gradually protrudes toward the central portion for pressing.

In addition, a switch button is attached to the opening formed in the member to be attached, a button cap is attached to the upper portion of the switch button, and the button cap is operated to operate a plurality of buttons arranged on the back side of the member to be attached. In the switch structure for individually operating the switches, a plurality of elastic switch operation pieces integrally formed with the attached member are formed in the opening of the attached member, and the switch button is provided on the rear surface of the switch button. Is provided with a raised portion having an inclined surface that gradually protrudes toward the central portion in order to individually press the switch operation pieces, and a protruding portion that protrudes downward is provided at a side end portion of the button cap. Is provided on the upper surface of the switch button and the surface of the button cap, and at least one has a convex portion and the other has a convex portion or a concave portion. That it is provided in the right asymmetrical position it is an feature.

Further, the switch operation piece described above is characterized in that the tip end portion thereof, which comes into contact with the inclined surface of the raised portion, is formed into a spherical shape.

[0009]

[Action]

 The switch operating piece, which has elasticity and operates multiple switches individually, is easily injection-molded with resin as a unit with the mounted member, so the number of switch parts does not increase and the structure is simple. Can be converted. The back surface of the switch button is provided with a raised portion having a sloped surface that gradually protrudes toward the central portion. When a part of the switch button is pressed, the switch button tilts and the raised portion is moved. The switch operation pieces are individually pressed by the inclined surfaces, and the switches corresponding to the pressed switch operation pieces are pressed to perform the switch operation.

After the switch operation, the switch button is automatically returned to the state before being pressed by the elasticity of the switch operation piece. Although the above is the case of the push switch, when the slide switch is to be used next, the gap between the switch button and the opening formed in the mounted member is provided by an amount enough for the switch button to slide.

Further, a protrusion protruding downward is provided at the side end of the switch button, and the protrusion allows the switch button to come into contact with the base of the switch operation piece even if the switch button is operated in the pressing direction. The switch button will not tilt and will not move in the pressing direction. Then, as in the case of the push switch, since the back surface of the switch button is provided with a raised portion having an inclined surface that gradually protrudes toward the center, sliding the switch button causes the raised portion of the back surface to move. By the inclined surface, the switch operation pieces in the sliding direction are individually pressed, and the switches corresponding to the switch operation pieces are pressed to perform the switch operation.

After the switch operation, the switch button is automatically returned to the state before sliding by the elasticity of the switch operation piece. With this switch structure, it is possible to adapt to a push switch or a slide switch by slightly changing the shape of the switch button end. By applying this, as a structure for attaching a button cap to the upper part of the switch button, a protruding part that protrudes downward is formed at the side end part of the button cap, and at least on the upper surface of the switch button and the back surface of the button cap. A convex portion is provided on one side and a convex portion or a concave portion is provided on the other side in an asymmetrical manner.

As a result, depending on the direction in which the button cap is attached to the switch button, the direction in which the convex portions and the convex portion or the concave portion of both are fitted or the direction in which they are overlapped without being fitted is generated. Since the height position where the switch button is attached to the button cap is different in the direction in which the convex portion and the convex portion or the concave portion are fitted to each other, the protruding portion and the switch formed on the side end portion of the button cap are different. The distance between the operation piece and the base changes.

Therefore, depending on the mounting direction of the button cap, a push switch structure or a slide switch structure can be easily formed with the same structure. The switch operation piece of the mounted member described above is provided with a spherical portion for contacting the inclined surface of the protruding portion provided on the lower surface of the switch button, so that the switch operation piece and the inclined surface of the protruding portion are formed. It can be prevented from being caught and the reliability is improved.

【Example】

 One embodiment of the present invention is shown in FIG. FIG. 1A is a plan view of a switch structure according to an embodiment of the present invention, and FIG. 1B is a sectional view. This embodiment shows an example applied to adjustment of contradictory functions such as the volume of an audio device. Reference numeral 10 denotes a member to be attached which constitutes a front plate of an audio device made of synthetic resin, and 11 is a switch operating piece which is formed in a leaf spring shape and has elasticity, and a switch button which is formed as an opening 12 in the member to be attached 10. In the present embodiment, the fitting position of 13 is injection-molded integrally with the mounted member 10 so as to face left and right in this embodiment.

On the back surface of the switch button 13, a raised portion 15 having an inclined surface that gradually protrudes toward the center is formed, and on both side surfaces of the switch button 13, the opening 12 of the mounted member 10 is formed. A claw 16 for fitting is provided. Further, the printed circuit board 4 is installed in parallel on the back side of the mounted member 10, and the switch 3 is placed on the printed circuit board 4 at a position where it can be pressed by the switch operation piece 11 according to the mounting position of the switch button 13. Solder mounted.

Further, in the switch operation piece 11, the switch pressing portion of the switch operation piece 11 is provided with a projecting portion 14 for surely pressing the switch 3, and further, an inclined surface of the raised portion 15 of the switch button 13. The tip end of the switch operation piece 11 that comes into contact with is formed in a spherical shape. Then, the switch button 13 is installed in the opening 12 of the mounted member 10 by the fitting claws 16 on both side surfaces.

In the switch structure configured as described above, when a part of the switch button 13 is pressed to operate a desired switch, for example, the left side is pressed as shown in FIG. 2, the switch is raised by the raised portion 15 on the lower surface of the switch button 13. Button 13 tilts to the left. Therefore, only the left switch operating piece 11 is pressed by the left inclined surface of the raised portion 15, and the left switch 3 is pressed.

A protrusion 17 is provided at the end of the switch button 13, and when the switch button 13 is tilted by a pressing operation, the protrusion 17 at the end of the switch button 13 becomes the base of the switch operation piece 11. By making contact with each other, the tilt range of the switch button 13 is restricted, and damage to the switch 3, the switch operation piece 11, etc. is prevented.

After the switch operation, the switch button 13 is pushed up by the elasticity of the switch operation piece 11 and automatically returns to the state before the push. By making the tip of the switch operation piece 11 which is the contact portion with the raised portion 15 spherical, it is possible to prevent the switch operation piece 11 and the inclined surface of the raised portion 15 from being caught when the switch button 13 is pressed. Therefore, the switch operation piece 11 can be pressed and returned smoothly, and the reliability can be improved.

FIG. 3 shows an embodiment in which the switch structure according to the present invention is applied to a slide switch, and the gap between the switch button 23 and the opening 22 formed in the mounted member 20 is set to be an excess as much as the switch button 23 can slide. It is provided. Further, in this embodiment, the distance between the protruding portion 27 at the end of the switch button 23 and the switch operating piece 21 is almost eliminated, so that even if the switch button 23 is pressed, the switch button 23 and the base of the switch operating piece 21 are Since the switch button 23 is in contact with the switch button 23, the switch button 23 does not tilt, and the switch operation is prevented from being performed by pressing the switch button 23.

On the lower surface of the switch button 23, as in the case of the push switch button shown in FIG. 1, a raised portion 25 having an inclined surface that gradually protrudes toward the center is formed. When the slide operation, for example, the slide operation to the left side as shown in FIG. 4, the raised portion 25 provided on the back surface of the switch button 23 also slides to the left side, and the left side inclined surface of the raised portion 25 pushes the left switch operation piece 21. Then, the switch 3 on the left side is pushed down.

After the switch operation, the elasticity of the switch operation piece 21 causes the switch button 23 to automatically return to the central stable position before the slide in which the elasticity of the left and right switch operation pieces 21 is balanced. Since the raised portion 25 of the switch button 23 comes into contact with the switch operation piece 21 from the lateral direction, the tip of the switch operation piece 21 with which the raised portion 25 comes into contact is made spherical, so that the switch operation piece 21 is not damaged. As a result, the switch operation piece 21 can be pressed and returned smoothly, and the reliability can be improved.

FIG. 5 is a front view and a side view showing a switch button, FIG. 5 (a) corresponds to the switch button 13 in the push switch system according to the embodiment of FIG. 1, and FIG. 5 (b) is shown in FIG. This corresponds to the switch button 23 in the slide switch system according to the embodiment. FIG. 6 is a switch structure configured to be applicable to both a push switch and a slide switch by using the same member by applying the difference between the protrusions 17 and 27 at the side ends of the switch button in the push switch and the slide switch. FIG.

Similar to the above, the gap between the switch button 33 and the opening 32 formed in the mounted member 30 is provided by the amount that the switch button 33 can slide, and the back surface of the switch button 33 gradually increases toward the center. A raised portion 35 having a protruding inclined surface and a claw 36 for fitting into the opening 32 of the mounted member 30 are formed. Furthermore, a left-right asymmetric convex pattern 38 is formed on the upper surface of the switch button 33.

A button cap 40 is attached so as to cover the switch button 33 from the upper surface. Inside the back surface of the button cap 40, a convex pattern 48 formed only on a certain direction of the convex pattern 38 formed on the upper surface of the switch button 33 is formed. Therefore, by changing the mounting direction of the button cap 40 by 180 degrees, the convex portion pattern 38 of the switch button 33 and the convex portion pattern 48 of the button cap 40 are not fitted and overlap each other (FIG. 6 (a)). There is a matching direction (Fig. 6 (b)).

As shown in FIG. 6A, in the direction in which the convex pattern 48 of the button cap 40 and the convex pattern 38 of the switch button 33 overlap each other, the switch button 33 is attached shallowly in the button cap 40, The projecting portion 47 at the end of the cap 40 projects slightly downward, so that the switch button 33 functions as a tilting push switch.

As shown in FIG. 6B, in a direction in which the button cap 40 and the convex pattern of the switch button 33 are fitted to each other, the switch button 33 is deeply attached inside the button cap 40, and the end portion of the button cap 40 is attached. Since the projecting portion 47 of the above largely projects toward the base side of the switch operating piece 31, it does not act in the pressing direction and becomes a slide switch.

That is, with the same switch configuration, by changing the mounting direction of the button cap 40, it is possible to easily form a push switch or a slide switch. FIG. 7A is a rear view of the button cap 40. As shown in FIG. 7A, the button cap 40 has a pair of fitting claws 49 of different lengths for fitting the button cap 40 and the switch button 33. , 50 are provided asymmetrically, and the lengths of the claws 49, 50 are the end portions of the switch button 33 when the convex pattern 48 of the button cap 40 and the convex pattern 38 of the switch button 33 are fitted to each other. It corresponds to the length to the lower surface of the switch button 33 and the length to the lower surface of both end portions of the switch button 33 when the convex pattern 48 and the convex pattern 38 overlap each other.

Further, recesses 39 are provided at both end portions of the switch button 33 so that the claws 49 or 50 which are not involved in fitting the button cap 40 and the switch button 33 can escape. The fitting caps 49 and 50 of the button cap 40 can be easily used as a push switch or a slide switch depending on whether the convex pattern 38, 48 overlaps or not.

In this embodiment, the projection patterns 38 and 48 are provided on both the upper surface of the switch button 33 and the back surface of the button cap 40. Can be Further, in the present embodiment, the left and right switch structures are used, but the same applies when a larger number of switches are installed.
