Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a multiple link switch used for various electronic devices.

BACKGROUND OF THE INVENTION With the development of digital circuit technology in recent years, there has been a rapid increase in electronic equipment and demand for smaller and thinner switches. As shown in Japanese Patent No. 1.34637, the structure was as shown in FIGS. 3 to 6. In other words, as shown in FIG.
A terminal plate 19 having terminals 16, 17, and 18 is inserted in the operating direction of the push button 20, and 20 is a push button for controlling the slider 21, which is provided in a direction perpendicular to the operating direction. It has a hole 22 and recesses 23, 23', and can slide inside the switch case 13. Reference numeral 24 denotes a U-shaped reversing spring, which connects the recesses 14 and 15 of the switch case 13 and the recesses 23 and 23' of the push button 20.
It is strung with. A plurality of switch elements 26 configured as described above are attached to the mounting bracket 26, and a push button? It is composed of a band-shaped leaf spring 27 attached so as to pass through the 20 holes 22.

Problems to be Solved by the Invention However, in the above configuration, the terminal plate 19 formed in a rectangular shape is fitted into the switch case 13 in the operating direction of the push button 20, and each terminal 16, 17 ．．
Since the switch 18 is exposed from the bottom surface of the switch case 13, it is difficult to reduce the overall height of the switch, which has the disadvantage that it cannot be used in ultra-thin electronic devices.

Therefore, the present invention aims to reduce the overall height of the switch, for example by 5.
By making it less than ff, it is possible to provide a multiple-action switch suitable for making electronic equipment thinner.

Means for Solving the Problem In order to solve this problem, the present invention provides a conductive, non-stretchable, and elastic band-like structure that is placed on a substrate on which a plurality of fixed contact portions are arranged in a row, with a spacer interposed therebetween. The interlocking body is disposed with only both ends fixed so as to face the fixed contact portion, and the interlocking body has the functions of both a movable contact piece and an interlocking function.

Function: With such a configuration, terminals are no longer necessary and the device can be made extremely thin.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is an exploded perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view of the same. 01 is an operating body 2 to be described later.
sb, has a vertical through hole 1a on the top surface, and a skirt portion 1b is formed at the bottom, and the case 1 is locked to a mounting body 4 to be described later. The engagement convex portion 1C and the pair of opposing surfaces of the inner wall have a receiving portion 1d for locking a leaf spring 3, which will be described later.

Reference numeral 2 denotes an operating body having a horizontal through hole 2a, an operating portion 2b protruding from the through hole 1a of the case 1, and slidably incorporated into the case 1, and an interlocking band to be described later. It has a convex portion 2C for operating 6. Reference numeral 3 designates a plate that is loosely inserted into the through hole 2a of the operating body 2 and supported so that its fulcrum portions 3a at both ends are bent by the receiving portions 1d of the case 1.

Reference numeral 4 denotes a mounting body for fixing and holding the operating units configured as described above in a line, and has a plurality of square holes 4a for fixing the case 1.

5 is non-stretchable and has conductivity and elasticity, and the operating body 2
It is an interlocking band that has a contact portion such as a cut-and-raised piece 5d directly below, and has holes 5a at both ends for fixing to a spacer 7 to be described later.
, sb, and the relationship between the distance 11 between the holes 5a and 5b and the distance 12 between the bosses 7b and 7C of the spacer 7 described below is 111>12.Furthermore, the fixed contact of the flexible base material 8, described later, is located only at one end. It has a hole 5C through which a conductive rivet 6 passes for electrical connection with 8C. 7 is a spacer for fixing only both ends of the interlocking band 5 and holding the interlocking band 5 at a constant distance from a fixed contact 8C described later. , has a groove 7d that is slightly larger than the width and thickness of the interlocking band 6, and bosses 7b and 7C are formed at both ends, and the hole sa of the interlocking band 5, respectively.
The 08 into which the sb is fitted and fixed has a plurality of fixed contacts 8a corresponding to the plurality of operation units, and also has a fixed contact 8C and a hole 8b at one end, and the conductive rivet 6
The interlocking band 5 and the fixed contact 8C are electrically connected by 09
is for protecting the flexible base material 8 from external forces, and
This is an under guard plate for determining the full stroke of the operating body 2. 10 to 12 are the mounting body 4 and the spacer N7.
This is an adhesive base material for fixing the spacer 7 and the flexible base material 8, and the lexical base material 8 and the under guard plate 9, respectively.

The operation of the multiple link switch configured as described above will be explained below. In FIG. 2, the leaf spring 3 is reversed upward, and due to this reverse reaction force, the operating body 2
is pushed upward and pressed against the inner wall top surface 1e of the case 1, and the fixed contact 8a and the interlocking band 5 are in a separated state. - The phallic spring 3' is inverted downward and the operating body 2' is pressurized downward by this inversion reaction force, so the interlocking band 5 is bent by the convex portion 2c' of the operating body 2'. Fixed contact 8a'
, and the cut and raised piece 5d of the interlocking band 5 and the fixed terminal 8a' are in a conductive state.

In this state, when the operating body 2 is pressed down, the interlocking band 6 begins to bend by the convex portion 2C of the operating body 2. When the operating body 2 is pressed down further, the leaf spring 3 is reversed downward and the operating body 2 is automatically pushed down. is pressurized downward, and the cut and raised piece 5d of the interlocking band 6 is brought into pressure contact with the fixed contact 8a by the convex portion 2C of the operating body 2, and the two are electrically connected. On the other hand, the convex 2c' of the operating body 2' is pushed upward by the bending action of the interlocking band 5, so that the plate spring 3'
is reversed upward, and due to this reverse reaction force, the operating body 2' is pressed against the inner wall top surface 1e' of the case 1', and the interlocking band 5
The cut and raised piece 5d and the fixed contact 8a' are separated.

Since the multiple band switch of the present invention is configured as described above, it can be made into a very thin multiple band switch.

In the text, 8 is a flexible base material, but of course it may be a printed base material, and in this case, the under guard plate 9
does not need to be used.

Effects of the Invention As described above, the present invention has a base material having fixed contacts arranged in a plane, and an interlocking band that has both an interlocking function and a movable contact piece using cut and raised pieces. This is a thin, multi-operation switch that has an excellent operating feel due to the reversing force of the leaf spring, and has very practical effects.
