Abstract

(57) [Abstract] [Purpose] The present invention relates to a panel switch used for operating electronic devices such as a video tape recorder, a television receiver, a copying machine, and a facsimile, and prevents deformation of a spacer used for the panel switch. However, it is an object of the present invention to provide a panel switch that can be easily assembled. [Arrangement] An air hole 17 is provided in a position insulating substrate 15 corresponding to the circumference of a through hole 16a of a spacer 16, and the air hole 1 is formed.
Since the air is removed by 7 and the spacer 16 is not processed at all, the spacer 16 can be easily assembled without being deformed at the time of attachment, and the adhesive of the spacer 16 is exposed at a part of the air hole 17. Therefore, it also has an effect of preventing dust and the like from entering the switch contact portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel switch used for operating electronic equipment such as a video tape recorder, a television receiver, a copying machine, and a facsimile.

[0002]

[Prior Art]

 In recent years, as electronic devices such as video tape recorders, television receivers, copiers, and facsimiles have become more multifunctional and higher in density, the panel switches used for operation are easier to assemble and lower in price. There is a demand for higher density wiring.

A conventional panel switch of this type will be described with reference to FIGS. 4, 5A and 5B.

According to FIG. 1, reference numeral 1 is a substrate, 2 is an elastic insulating substrate 5 having a plurality of contacts 3 and wiring conductors 4 formed on one side thereof, and is bent to form an upper insulating substrate 5a and a lower insulating substrate 5b. A switch portion 6 is arranged such that the contacts 3 face each other between the substrate 5a and the lower insulating substrate 5b, and a switch portion 6 is inserted between the upper insulating substrate 5a and the lower insulating substrate 5b and has a through hole 6a and an air groove 6b in the switch contact portion. Then, 8 is a case, and 9 is an operation button, which is a spacer attached to the insulating substrate 5 with an adhesive applied on one or both sides.

In the above structure, when the operation button 9 is pressed with a hand, the lower end of the operation button 9 deforms the upper insulating substrate 5a, the upper and lower switch contacts 3 come into contact and turn on, and when the hand is released, the upper button is elastically moved upward. The insulating substrate 5a is restored and the upper and lower switch contacts 3 are separated and turned off.

[0006]

[Problems to be solved by the device]

 However, in the above-described conventional configuration, the air groove 6b is provided in the spacer 6 to prevent air accumulation when the spacer 6 is attached to the insulating substrate 5 and to prevent the deterioration of the feeling due to the thermal expansion of air in the contact portion at high temperature. Therefore, there is a problem that the spacer 6 is easily deformed and it is very difficult to attach the spacer 6 to the insulating substrate 5.

The present invention solves the above problems, and an object of the present invention is to provide a panel switch that prevents deformation of the spacer and is easy to assemble.

[0008]

[Means for Solving the Problems]

 In order to solve this problem, the panel switch of the present invention has a structure in which an air hole is provided at the position of the insulating substrate on the circumference of the through hole when the spacer is attached to the insulating substrate, and this air hole is used to remove air. It is a thing.

[0009]

[Action]

 With the above structure, since the air groove of the spacer is not necessary, the spacer can be easily assembled without being deformed during attachment.

[0010]

【Example】

 (Embodiment 1) Hereinafter, an embodiment of the panel switch of the present invention will be described with reference to FIGS. In the description, the same parts as those in the prior art will be designated by the same reference numerals. In the figure, reference numeral 15 is an elastic insulating substrate having a plurality of contacts 3 and wiring conductors 4 formed on one side, and is bent to form an upper insulating substrate 15a and a lower insulating substrate 15b, and an upper insulating substrate 15a and a lower insulating substrate 15a. The contacts 3 face each other between the insulating substrates 15b. Reference numeral 16 is a spacer which is inserted between the upper insulating substrate 15a and the lower insulating substrate 15b, has a through hole 16a in the switch contact portion, and is attached to the insulating substrate 15 by an adhesive applied on one side or both sides. Further, an air hole 17 is provided in the upper insulating substrate 15a at a position corresponding to the circumference of the through hole 16a when the spacer 16 is attached. Since the air hole 17 is provided at a position corresponding to the circumference of the spacer 16, the air hole 17 is partially blocked by the spacer 16.

In the present embodiment configured as described above, since the spacer 16 has no air groove, the insulating substrate 15 and the spacer 16 can be attached very easily.

It should be noted that the structure in which the switch is made by bending the insulating substrate having elasticity to form the upper insulating substrate and the lower insulating substrate with the spacers attached therebetween is only one example, and as shown in FIG. Even if the spacer 22 is attached between the upper insulating substrate 21 and the upper insulating substrate 21 and the air holes 23 are provided in the upper insulating substrate 21, or the air holes are provided in the lower insulating substrate, the scope of the present invention can be improved. Of course it is inside.

[0013]

[Effect of the device]

 As described above, according to the present invention, when the spacer of the insulating substrate is attached, the air hole is provided at the position corresponding to the circumference of the through hole, and the air is vented by the air hole. Assembly of the spacer is very easy, and part of the air hole is blocked by the spacer, and the adhesive on the spacer is exposed inside the air hole, preventing dust and other contaminants from entering the switch contact section. It also has the effect of making it possible to realize an excellent panel switch.
