[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to a video tape recorder,
The present invention relates to a panel switch used for operating electronic devices such as a television receiver, a copying machine, and a facsimile.

2. Description of the Related Art In recent years, as electronic devices such as video tape recorders, television receivers, copiers, and facsimile machines have become more multifunctional and higher in density, panel switches used for operation have been more easily assembled. There is a demand for lower prices and higher wiring densities.

A conventional panel switch of this type will be described with reference to FIGS. 4, 5 (a) and 5 (b).

According to FIG. 1, reference numeral 1 denotes a substrate, and 2 denotes an elastic insulating substrate 5 having a plurality of contacts 3 and wiring conductors 4 formed on one surface thereof, and is bent into an upper insulating substrate 5a and a lower insulating substrate 5b. A switch portion 6 is provided between the upper insulating substrate 5a and the lower insulating substrate 5b so that the contact 3 is opposed between the lower insulating substrate 5a and the lower insulating substrate 5b.
a, an air groove 6b, a spacer affixed to the insulating substrate 5 with an adhesive applied to one or both surfaces, 8 is a case, 9 is an operation button.

In the above configuration, the operation button 9 is manually
Is pressed, the lower end of the operation button 9 deforms the upper insulating substrate 5a, and the upper and lower switch contacts 3 come into contact and turn on,
When the hand is released, the upper insulating substrate 5a returns due to elasticity, and the upper and lower switch contacts 3 are separated and turned off.

[0006]

However, in the above-mentioned conventional structure, the air gap at the time of attaching the spacer 6 to the insulating substrate 5 and the feeling deterioration due to the thermal expansion of the air at the contact portion at a high temperature are prevented. Since the air groove 6b is provided in the spacer 6, 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.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a panel switch which prevents deformation of a spacer and is easy to assemble.

[0008]

In order to solve this problem, the panel switch according to the present invention provides an air hole at a position of the insulating substrate on the circumference of the through hole when attaching the spacer to the insulating substrate. The air vent is used to release air.

[0009]

According to the above construction, since the air groove of the spacer is not required, the spacer can be easily assembled without being deformed at the time of sticking.

[0010]

FIG. 1 shows an embodiment of the panel switch according to the present invention.
This will be described with reference to FIG. In the description, the same parts as in the related art will be denoted by the same reference numerals. In the figure, reference numeral 15 denotes an elastic insulating substrate having a plurality of contacts 3 and wiring conductors 4 formed on one surface, and is bent to form an upper insulating substrate 15a and a lower insulating substrate 15b.
The contact 3 is made to oppose between 5a and the lower insulating substrate 15b. 16 is an upper insulating substrate 15a and a lower insulating substrate 15b
Between the switch contact portion and a through hole 16a,
The spacer is attached to the insulating substrate 15 with an adhesive applied to one or both surfaces. Further, the upper insulating substrate 15a is provided with an air hole 17 at a position on the circumference of the through hole 16a when the spacer 16 is attached. Since the air holes 17 are provided at positions on the circumference of the spacer 16, the air holes 17 are partially closed by the spacer 16.

In this embodiment constructed as described above, since there is no air groove in the spacer 16, it is very easy to attach the insulating substrate 15 and the spacer 16.

The switch is formed by bending an elastic insulating substrate to form an upper insulating substrate and a lower insulating substrate and attaching a spacer between the upper insulating substrate and the lower insulating substrate. This is only one example, and as shown in FIG. A configuration in which the spacer 22 is attached between the upper insulating substrate 21 and the upper insulating substrate 21 and the air hole 23 is provided in the upper insulating substrate 21 or a configuration where the air hole is provided in the lower insulating substrate 21 is within the scope of the present invention. Of course.

[0013]

As described above, according to the present invention, an air hole is provided at a position on the circumference of a through hole when a spacer of an insulating substrate is attached, and air is evacuated by the air hole. And the spacers are very easy to assemble, and the air holes are partially closed by the spacers, and the adhesive on the spacers is exposed inside the air holes to prevent dust and other foreign matter from entering the switch contacts. Thus, an excellent panel switch can be realized.
