Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a push button switch used in an operation switch section of an electronic device.

2. Description of the Related Art In recent years, with the rapid digitization of various devices,
The number of operation switches that use thin, easy-to-assemble seat-integrated diaphragms for the operation parts of equipment is rapidly increasing. An example of a conventional push button switch using this type of diaphragm is shown in FIGS. 10 to 12. 10 to 12,
In the push button switch, a lower contact 2 is provided at a predetermined position on the lower insulating substrate 1, and a spacer 3 having a predetermined thickness having a through hole 3a at a position corresponding to the lower contact 2 is provided on the lower insulating substrate 1. The lower contact 2 and the through hole 3a are aligned with each other, and the upper contact 4 is provided on the lower contact 2 at a position corresponding to the lower contact 2. And a plurality of diaphragms 6 integrally provided on the upper part of the diaphragm sheet 7 at fixed intervals P so that the diaphragm 6 is aligned with the positions of the upper and lower contacts 2 and 4 and stacked. , And the upper and lower contacts 2, 4 on it
A case 9 having a through hole 8 formed at a position corresponding to is formed integrally by stacking the upper and lower contacts 2 and 4 and the push button 10 in a state where the push button 10 is loosely fitted in the through hole 8. ing.

In the above push button switch, when the push button 10 is pushed, the leg portion 10a pushes the central portion of the diaphragm 6 of the seat 7, and the diaphragm 6 and the upper insulating substrate 5 therebelow are set inside the through hole 3a. It is displaced downward, and the upper contact 4 and the lower contact 2 facing each other come into contact with each other to close the circuit. When the push button 10 is released, the upper and lower contacts 2 and 4 are separated by the restoring force of the diaphragm 6 and the upper insulating substrate 5,
The circuit returns to the initial open state.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention The diaphragm sheet 7 used in the above-mentioned conventional push button switch, which is formed by arranging and integrating a plurality of diaphragms 6, has the diaphragms 6 arranged at equal intervals for ease of manufacturing. ing. However, with the recent miniaturization of various devices, multifunctionalization, and diversification of designs, in the above-described conventional equally spaced diaphragm 6, a plurality of pushbutton switches are formed at equal intervals or an integral multiple thereof. However, there is a problem in that the flexibility of the position of the pushbutton switch is significantly impaired.

The present invention solves the conventional problems as described above, and the position of the push button switch is changed by adjusting the distance between the diaphragms in a diaphragm sheet integrally provided with a plurality of diaphragms at equal intervals. It is intended to provide a push button switch.

Means for Solving the Problems In order to solve the above problems, a push button switch according to the present invention comprises a diaphragm sheet integrally formed by arranging a plurality of diaphragms at equal intervals, and at least one set of adjacent diaphragms. At least either a convex portion or a bent portion is formed therebetween to reduce the interval between the adjacent diaphragms, and a push button is provided by loosely fitting in a case on the upper surface side of a predetermined diaphragm, and the lower surface side thereof. An elastic upper insulating substrate having an upper contact and a lower insulating substrate having a lower contact are integrated at a predetermined interval so that the upper and lower contacts face each other at a position corresponding to the diaphragm. It was formed.

According to the above-mentioned structure of the present invention, at least either a convex portion or a bent portion is formed with the diaphragm sheet integrally formed by arranging a plurality of diaphragms at equal intervals. As a result, the distance between the diaphragms is changed or the angle is changed, so that it is possible to obtain a push button switch in which the spacing and the direction of the arrangement are changed with the same assembly workability as in the past.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic sectional view of a push button switch according to an embodiment of the present invention. In FIG. 1, a switch panel 11 is provided with a plurality (five) of push button switches 12A to 12E arranged in a predetermined arrangement, and a case 14 in which the push buttons 13 are loosely fitted in the predetermined arrangement.
And a diaphragm sheet 17 in which a plurality of diaphragms 15 arranged below the case 14 are arranged to be integrally formed with a sheet-like member 16, and an upper contact 18 arranged on the lower surface side of the diaphragm sheet 17 is a lower surface. And an upper insulating substrate 19 having elasticity and a lower contact 21 facing the upper contact 18 arranged at a predetermined interval on the upper insulating substrate 19 via a spacer 20.
Is composed of a lower insulating substrate 22 provided on the upper surface side, and in each push button switch 12, the push button 13, the diaphragm 15, the upper contact 18 and the lower contact 21 are aligned and laminated so that they are vertically overlapped at the same position, By pressing the push button 12, the upper contact 17
And the lower contact 21 are in contact with each other.

In the diaphragm sheet 17, as shown in FIG. 3, the diaphragm 15 has nineteen diaphragms in two rows (14a to 14i).
They are arranged at equal intervals P, but on the seat member 16 between the fourth and fifth diaphragms 15d and 15e from the left of each row,
The convex portion 16a is formed by pressing from below, and the distance between the diaphragms 15d and 15e is Q which is smaller than P. As a result, the diaphragm in the switch panel 11
Pushbutton switch 12A and diaphragm 15e formed by 15b
The distance from the push button switch 12B formed in step 2P + Q is 2P + Q. As shown in FIG.
The intervals of 2C, 12C and 12D, 12D and 12E are P or integer multiples (2 times) of P, but they are modulated, so that the degree of freedom in arranging the push button switch 12 in the switch panel 11 is increased. ing.

The shape of the convex portion 16a is not limited to the acute angle mountain shape as shown in FIG. 1, but also the rectangular shape as shown in FIG. 4 and the rising portions on both sides of the convex portion 16 as shown in FIG. A plurality of folded ones or a mountain-shaped one as shown in FIG. 6 may be provided.
Further, a convex portion 16a may be provided between a plurality of sub diaphragms adjacent to each other, and the degree of freedom of arrangement of the push button switches 12 is further increased.

7 to 9 show a push button switch according to another embodiment of the present invention, in which a bent portion is provided at one place of the diaphragm sheet 17.
By forming the pushbutton switches 12 in the right angle direction by forming 16b, the position, number, angle, etc. of the bent portions 16b can be arbitrarily set, and the pushbutton switches 12 can be arranged in various patterns.

As described above, the diaphragm sheet 17 is easy to handle because it does not divide but simply forms a convex portion or a bent portion when forming the push button switches 12 arranged in different intervals and patterns. Therefore, the assembly workability is good, and it is also possible to form the convex portion or the bent portion between the adjacent diaphragms of the diaphragm sheet 17 at the time of manufacturing the diaphragm sheet 17, and perform the assembly work with high efficiency. You can

Effects of the Invention As described above, in the push button switch of the present invention, a convex portion or a bent portion is formed between the adjacent diaphragms of the diaphragm sheet, and the diaphragms can be arranged at intervals and patterns with a degree of freedom. Since it is not necessary to divide it and it can be mounted as an integrated sheet, it is easy to handle and has good assembly workability.In addition, when manufacturing a diaphragm sheet, it is possible to form convex parts between diaphragms or bend parts. Since it can be formed, the assembling work can be performed with high efficiency.
