Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite switch used for various electronic devices such as information terminal devices and operated by tilting and pressing an operation unit.

[0002]

2. Description of the Related Art In recent years, electronic devices such as information terminal devices have been increasingly miniaturized and diversified in operation functions.

In order to operate these diversified functions, many switches are used in electronic devices, and it is necessary to reduce the number of operation units on an operation surface in order to downsize the devices. In some cases, a method has been adopted in which an operation mechanism for operating a plurality of switches collectively is incorporated as a component of an electronic device.

[0004]

However, in the above-described method of incorporating an operating mechanism as a component of an electronic device, the number of switches that can be operated by a single operation unit is limited, and the electronic device is incorporated in the electronic device. There has been a problem that it is difficult to engage the operation mechanism with the switch, and the cost of the electronic device increases.

The present invention has been made to solve such a conventional problem, and a plurality of switches can be individually operated by tilting or pressing a single operation unit. It is an object of the present invention to provide a composite switch as a pre-integrated electronic component that can be operated in two steps and can be operated continuously.

[0006]

Means for Solving the Problems In order to solve the above problems, the present invention has the following arrangement.

[0007] The invention described in claim 1 of the present invention is capable of swinging about a midpoint of two opposing sides of a square as viewed from above, as a fulcrum,
An operating body supported by the case, a push button penetrating through the center of the operating body and arranged to be movable up and down, and sandwiching the swing center axis of the case below the tilting directions when the operating body swings. A composite switch consisting of a peripheral push switch arranged at two symmetrical positions and having different operation strokes arranged on one side, and a central push switch arranged in the case below the push button When the operating body is tilted in one direction by tilting the operating body of one operating unit including an operating body and a push button disposed in the center of the operating body, the two peripheral push switches in the tilting direction lower are One of them can be operated by pressing first, and the other can be operated by further tilting, and the central push switch can be operated by pressing the push button. Effect that can realize the switch is obtained.

According to a second aspect of the present invention, in the first aspect of the present invention, in particular, the peripheral push switch and the central push switch are each formed of elastic metal on a fixed contact which is insert-molded and fixed in a case. It is formed by mounting a thin circular dome-shaped movable contact, and arranging a driving body made of an insulating material on the top, and is formed compactly and inexpensively as a whole push switch and composite switch. The operation and effect that the push switch has a sense of moderation during operation can be obtained.

According to a third aspect of the present invention, in the first aspect of the present invention, in particular, each of the peripheral push switches presses the movable contact via a driving body formed of an elastic insulating material. It is a type, and by compressing and elastically deforming a driving body made of an elastic insulating material, it is possible to increase a pressing operation stroke of a peripheral push switch and easily set an operation stroke to a predetermined size. Is obtained.

According to a fourth aspect of the present invention, in the third aspect of the present invention, the tip of the driving body of the peripheral push switch has a spherical shape, and the lower surface of the operating body abuts on the apex thereof. When the operating body is tilted and swung in one direction, and when the driving body of the peripheral push switch is pressed down on its lower surface, the lower surface of the operating body always presses the apex of the driving body. The effect that the peripheral push switch can be operated stably can be obtained.

According to a fifth aspect of the present invention, in the third aspect of the present invention, in particular, two peripheral push switches arranged at symmetric positions with respect to the swing center axis of the case are provided. The driving bodies are connected and integrated, and each of the driving bodies is independently elastically deformable. Since the driving bodies of the two peripheral push switches are integrated, the number of constituent members of the entire composite switch is reduced. It is easy to assemble with less power, and the position of the two driving bodies is stable, and it is easy to make the operation strokes of the two peripheral push switches corresponding to the one driving body almost the same. Is obtained.

According to a sixth aspect of the present invention, in the fifth aspect of the present invention, in particular, two peripheral push switches arranged symmetrically with respect to the center axis of oscillation of the case are provided. Two sets of drive units that are connected and integrated are made of an elastic insulating material with the same shape and dimensions and different compression elastic coefficients, and two sets of drive units that are connected and integrated with the drive units of two peripheral push switches Since the body can be formed of two types of elastic insulating materials having different compression elastic moduli using the same molding die, the effect of reducing the number of necessary molding dies can be obtained. .

According to a seventh aspect of the present invention, in the invention of the fifth aspect, in particular, connection of two peripheral push switches arranged symmetrically with respect to a swing center axis of the case. Since two integrated driving bodies are formed at the same height with the same elastic insulating material and have different outer diameters or thicknesses, and the two driving bodies are formed of the same elastic insulating material, The operational effect is obtained that these two sets of driving bodies can be simultaneously formed by one molding die.

The invention according to an eighth aspect of the present invention is the invention according to the third aspect, in particular, in which the driving bodies of all the peripheral push switches are made of the same elastic insulating material and have the same shape and dimensions, and have the same specifications. The operating forces of the movable contacts of the two peripheral push switches arranged on one side of the swing center axis of the case are different from each other. Although two types of movable contacts are required for the peripheral push switch to be installed, it takes more time and effort to process, and the cost can be reduced by using a single type of high-cost driving body. The effect that the cost can be reduced can be obtained.

According to a ninth aspect of the present invention, in the first aspect of the present invention, in particular, the push button can be independently moved up and down with respect to the through hole at the center of the operating body so as to swing together with the operating body. And the central push switch presses the movable contact through a driving body made of a rigid insulating material. The upper end of the driving body is in contact with the lower surface of the push button. During the tilting operation of the operating body, both the push buttons can be tilted smoothly while the lower surface thereof slides between the upper ends of the corresponding driving bodies, and the push button is pressed to press the central push switch. In such a state, it is possible to obtain the effect of operating the peripheral push switch by tilting the operation body.

According to a tenth aspect of the present invention, in the invention of the ninth aspect, an operation knob which moves up and down and swings together with the push button is attached to the tip of the push button. By operating the peripheral push switch by tilting one of the operation knobs, the central push switch can be individually operated by pressing the operation knob, and by operating the tilt while holding down the operation knob, Thus, an operational effect can be obtained in that a composite switch capable of operating the central push switch and the central push switch continuously can be provided.

(Embodiment) FIG. 1 is an external perspective view of a composite switch according to an embodiment of the present invention, FIG. 2 is a side sectional view thereof, FIG. 3 is a front sectional view thereof, and FIG. FIG. 5 is an exploded perspective view taken along a line PP.

In FIG. 1, reference numeral 1 denotes a box-shaped case made of an insulating resin and having a rectangular shape in a top view, and first to second peripheral push switches 2 to 5 (hereinafter, referred to as first to fourth corners) near four corners on the bottom surface. A central push switch 6 (hereinafter, referred to as a central switch 6) is provided at the center (refer to FIG. 6), and a center of two opposing walls is provided at the center. , Two support holes 1A for swingably supporting an operation body 7 described later.

The first switch 2 to the fourth switch 5
As shown in FIG. 4 and FIG. 5, the contact portions are provided at two positions symmetrical with respect to a line connecting two support holes 1A of the case 1 serving as a swing center axis of the operating body 7. A fixed contact 8 composed of an outer peripheral contact 8A and a central contact 8B, a fixed contact 9 composed of an outer peripheral contact 9A and a central contact 9B, and a fixed contact 10 composed of an outer peripheral contact 10A and a central contact 10B, which are insert-molded and fixed in four recesses. And a fixed contact 11 composed of an outer peripheral contact 11A and a central contact 11B, and a circular dome-shaped movable contact 2A, 3A, 4A made of an elastic metal thin plate is provided on each outer peripheral contact 8A, 9A, 10A and 11A.
And 5A are placed on the outer periphery of the lower surface, and the center of the lower surface is opposed to the center contacts 8B, 9B, 10B and 11B, respectively, and is turned ON / OFF by being pressed from above, and has a compact contact structure. .

The above-mentioned four movable contacts 2A to 5A have the same shape and dimensions and substantially the same reversing operation force.
That is, the four contact portions have substantially the same switch operating force.

Then, the first switch to the fourth switch 5
Drivers 2B to 5B made of an elastic insulating material such as rubber are mounted on the movable contacts 2A to 5A of the respective contact portions, and the movable contacts 2A of the respective contact portions via the drivers 2B to 5B. By pressing ~ 5A, the first switch 2 ~
The fourth switch 5 is configured to operate with a large pressing operation stroke.

The driving bodies 2B to 5B are provided in the case 1
2 symmetrical two lines across the line connecting the two support holes 1A
B and 3B and 4B and 5B are connected and integrated to form connection driving bodies 12 and 13 having the same shape and dimensions.
Each of the driving bodies 2B to 5B can be elastically deformed independently.

By adopting such a configuration, the number of constituent members of the composite switch as a whole is small, it is easy to assemble, and the distance between the two drivers 2B, 3B and 4
The positions between B and 5B are stable, and the pressing operation strokes of two peripheral push switches 2 and 3 and 4 and 5 are the same.

Although the connecting driving bodies 12 and 13 are formed by using the same molding die, the connecting driving body 12, ie, the driving bodies 2B, 3B, is higher than the connecting driving body 13, ie, the driving bodies 4B, 5B. It is formed of a hard elastic insulating material having a large compression elastic coefficient, that is, a small amount of compressive deformation for the same pressing force.

On the other hand, the central switch 6 is also the case 1
A circular dome shape made of an elastic metal thin plate is formed on the outer peripheral contact 14A of the fixed contact 14 including the outer peripheral contact 14A and the central contact 14B insert-molded and fixed in a recess provided at the center of the line connecting the two support holes 1A. A contact portion is formed by placing the outer periphery of the lower surface of the movable contact 6A and making the center of the lower surface face the center contact 14B, and a driving body 15 made of a rigid insulating material is placed on the upper portion of the movable contact 6A.

FIG. 6 is a plan view showing a state where the first to fourth switches 5 and the center switch 6 are arranged in the case 1.

The upper surface of the case 1 accommodating the switches 2 to 6 has a metal cover 1 having five holes 16A through which the upper halves of the drivers 2B to 5B and 15 penetrate.
The operation body 7 and the push button 17 made of insulating resin are mounted on the upper part of the operation body 7.

The configuration of the mounting portion is such that two circular protrusions 7B (see FIG. 3) provided below the two opposite sides of the substantially rectangular flat plate portion 7A of the operating body 7 are two of the case 1. The operating body 7 is inserted into the support hole 1A, and
A line connecting A is swingably supported as a swing center axis, and an outer peripheral portion of the push button 17 can be vertically moved independently but swings together by a non-circular through hole 7C at the center of the operating body 7. Engaged and held as described above.

On the lower surface of the flat plate portion 7A of the operating body 7, an upper end 2C of four driving bodies 2B to 5B having a spherical shape is provided.
5C are in contact with each other, and the lower end surface of the push button 17 is in contact with the spherical upper end portion 15A of the driving body 15 of the central switch 6.

The composite switch according to the present embodiment is constructed as described above. Next, as shown in the side sectional view of FIG. 7, the operation knob 18 is inserted into the non-circular holding hole 17A at the tip of the push button 17. The operation in the case of mounting and operating will be described.

In the normal state, all the contact portions of the first to fourth switches 5 and the center switch 6 of the present composite switch are in the OFF state.
The operation knob 18 is in a horizontal state as shown in FIG. 8 which is a cross-sectional view taken along the line QQ in FIG. 6 in a state where the operation body 7, the push button 17, and the operation knob 18 are mounted.

In this state, as a first operation, when a downward pressing force is applied to the upper left surface of the operation knob 18, as shown in the side sectional view of FIG. 9 (however, the operation knob is not shown in cross section). The operating knob 18, the push button 17 to which the operating knob 18 is attached, and the operating body 7 in which the outer periphery thereof is engaged
Swings around a line connecting the two circular projections 7B below the operating body 7 supported by the two support holes 1A, and is tilted to the left.

Then, as the left side of the operating body 7 is lowered, the driving body 2 which comes into contact with the lower surface on the left side of the flat plate portion 7A.
The upper ends 2C and 4C of the spherical shapes B and 4B are pushed downward, and the driving bodies 2B and 4B push the movable contacts 2A and 4A of the lower first switch 2 and third switch 4 downward while compressing and deforming themselves. Press

However, since the elastic insulating material forming the driving body 2B has a larger compression elastic coefficient than the elastic insulating material forming the driving body 4B as described above, the downward pressing stroke, that is, the compression stroke is the same. Even if there is, the driving body 2B has a smaller amount of compressive deformation, so that the driving body 2B
The force that pushes the lower movable contact 2A is greater than the force that the driver 4B pushes the movable contact 4A.

For this reason, when the pressing stroke of the operating knob 18, that is, the amount of tilt of the operating body 7 becomes larger than a predetermined value, first, the pressing force of the driving body 2 B against the movable contact 2 A reverses the circular dome-shaped movable contact 2 A. As shown in FIG. 9, the movable contact 2A is elastically inverted with a sense of moderation, and the outer peripheral contact 8A of the fixed contact 8 and the central contact 8B are short-circuited via the movable contact 2A. .

As a result, the first switch 2 operates,
The signal is transmitted to a circuit of an electronic device using the composite switch via an output terminal (not shown) connected to each contact.

At this time, since the pressing force of the driving body 4B on the movable contact 4A of the third switch 4 is smaller than the reversing operation force of the movable contact 4A, a sectional view taken along the same cutting line as that of FIG. As shown in FIG. 10, only the first switch 2 operates and the third switch 4
Is deformed by compression, but the movable contact 4A does not perform the reversing operation.

Then, from this state, the pushing force applied to the operation knob 18 is increased, and as shown in the side sectional view of FIG. 11 (however, the operation knob is not shown in cross section), when the left side of the operation body 7 is further lowered, When the upper ends 2C and 4C of the driving bodies 2B and 4B are further pressed, the driving body 2B of the first switch 2 is compressed and deformed while the movable contact 2A is pressed against the center contact 8B, and the driving body 4B of the third switch 4 is also pressed. Further, when the amount of compression and deformation becomes equal to or more than a predetermined value and the pressing force on the movable contact 4A exceeds the reversing operation force of the movable contact 4A, a cross-sectional view similar to that of FIG. As shown in FIG. 12, the movable contact 4A is elastically inverted with a sense of moderation, and the movable contact 4A
The outer peripheral contact 10A of the fixed contact 10 and the central contact 10
B is short-circuited, and the third switch 4 operates.

Thereafter, when the pressing force applied to the operation knob 18 is removed, the movable contacts 2A and 4A and the driving members 2B and
B tries to return to the original shape by the elastic restoring force, and pushes back the operating body 7, the push button 17 and the operating knob 18 to the original positions, thereby returning to the normal state shown in FIGS. 7 and 8. The switch 2 and the third switch 4 are turned off again.

Similarly, when a downward pressing force is applied to the upper right surface of the operation knob 18, the second switch 3 and the fourth switch 5 can be operated.

As described above, the first switch 2 and the third switch 4 or the second switch 3 are operated by tilting the operating body 7 and the push button 17 by applying a pressing force to the left upper surface or the right upper surface of the operation knob 18. And the fourth switch 5 can be operated in two steps at different operation strokes.

At this time, the lower surfaces of the flat plate portion 7A of the operating body 7 that has been tilted at this time press the driving bodies 2B, 4B and 3B.
The upper ends 2C and 4C and 3C and 5C of the driving bodies 2B and 4B and 3B and 5B are always spherical.
Since the vertex of B is pressed, the first to fourth switches 5 to 5 can be operated stably.

Further, when a downward pressing force is applied to the upper left surface or the upper right surface of the operation knob 18 to tilt the operating body 7 and the push button 17, almost no downward force is applied to the push button 17. The lower end face is the driving body 1 of the central switch 6.
The center switch 6 does not operate only by moving along the upper end portion 15A of the spherical shape of FIG.

Next, as a second operation, FIGS.
When a downward pressing force is applied to the center of the upper surface of the operation knob 18 in the normal state shown in FIG. 13, the push button 17 having the operation knob 18 mounted on the engagement hole 17A is pressed as shown in the side sectional view of FIG. Then, the driving body 15 of the central switch 6 moves downward independently of the operating body 7 and contacts the lower end thereof.
, The center of the spherical upper end 15A is pushed downward, and the driving body 15 pushes the movable contact 6A of the central switch 6 therebelow.

When the pressing force on the movable contact 6A becomes larger than the reversing operation force of the circular dome-shaped movable contact 6A, as shown in FIG. 13, the movable contact 6A elastically inverts with a sense of moderation, and 6A, the outer peripheral contact 14A of the fixed contact 14 and the central contact 14B are short-circuited.

As a result, the central switch 6 operates,
The signal is transmitted to a circuit of an electronic device using the composite switch via an output terminal (not shown) connected to each contact.

Thereafter, when the pressing force applied to the operation knob 18 is removed, the movable contact 6A attempts to return to the original circular dome shape by the elastic restoring force, and the driving body 15 and the push button 17 are pressed.
By pushing back the operation knob 18 to the original position, the normal state shown in FIGS. 7 and 8 is restored, and the central switch 6 is again turned off.

When pressing the push button 17 by applying a downward pressing force to the center of the upper surface of the operation knob 18, the push button 17 only moves up and down independently of the operation body 7, so that the operation body 7 The first switch 2 to the fourth switch 5 do not operate.

Then, as a third operation, in the above-described second operation, the operation knob 18 is pressed downward to elastically invert the movable contact 6A of the central switch 6, and the outer contact 14A of the fixed contact 14 In the state where the center contact 14B is short-circuited and the center switch 6 is operated, when a further pressing force is applied in a direction to tilt the operation knob 18 to the left, as shown in a side sectional view of FIG. The push button 17 to which this is mounted and the operating body 7 with which the outer periphery is engaged
Swings around the line connecting the two circular protrusions 7B at the lower part of the operating body 7 supported by the two support holes 1A of the case 1 as the center line, as in the case of the first operation described above, and moves leftward. It is inclined to.

When the first switch 2 and the third switch 4 on the lower left side of the flat plate portion 7A are operated in two steps with different operation strokes when the operating body 7 is tilted, the case of the first operation described above Is exactly the same as that described with reference to FIGS.

Thereafter, when the downward and tilting pressing forces applied to the operation knob 18 are removed, the movable contacts 2A, 4A and 6A of the first switch 2, the third switch 4, and the center switch 6, and the driving body 2B 4B, the first switch 2, the third switch 4, and the center switch 6 are turned off by the elastic restoring force of the first operation and the second operation. Is the same.

Similarly, in a state where the operation switch 18 is pressed and the center switch 6 is operated, the operation knob 1 is further moved.
When a pressing force is applied in a direction to incline 8 to the right, the second switch 3 and the fourth switch 5 can be operated in two steps.

When a downward pressing force is applied to the operation knob 18 and a pressing force in the direction of tilting leftward or rightward is applied, the lower end surface of the push button 17 is driven by the driving body 15 of the central switch 6. The upper end 15A of the driving body 15 can move while sliding smoothly because the upper end 15A of the driver 15 has a spherical shape.

As described above, according to the present embodiment, the push button 1
By tilting one operating knob 18 as an operating unit attached to the holding hole 17A at the tip of the 7, one side of the swing center axis of the operating body 7 of the peripheral first to second switches 5 to 5. Can be operated in two steps, and the central switch 6 can be operated by pressing.
Can be operated individually, and the operation knob 18
When the tilting operation is performed while the button is pressed, the central switch 6 and the peripheral first to fourth switches 5
Can be continuously operated, and a composite switch as an electronic component integrated in advance can be realized.

In the composite switch according to the present embodiment described above, the driving bodies 2B to 5B of the peripheral first to fourth switches 5 are symmetric with respect to the two support holes 1A of the case 1. 2B, 3B and 4B by two,
5B are connected and integrated to form a connected driving body 1 having the same shape and dimensions.
2 and 13, the connection driving body 12, ie, the driving bodies 2B, 3B, and the connection driving body 13, ie, the driving body 4B,
5B is formed of an elastic insulating material having a different compressive elasticity coefficient so that the amount of compressive deformation with respect to the pressing force is different. And the third switch 4 and the second switch 3 and the fourth switch 5 are operated in two steps at different operation strokes.

However, as shown in FIG. 15 which is a cross-sectional view of a composite switch in which the driving body of the peripheral push switch is changed from the above configuration, two support holes 1A of the case 1 are provided.
, Two driving bodies 19, 20 and 21, 22 (not shown, 20 and 22) which are symmetrical about a swing center axis which is a line connecting the connecting driving bodies 23 and 24 are the same. It is made of an elastic insulating material at the same height, and circular holes 21A, 22A (2
2A is not shown) to reduce the thickness in the radial direction so that the driving bodies 21 and
The amount of compressive deformation with respect to the pressing force of 22 can be made larger than the driving bodies 19 and 20 on the connecting driving body 23 side.

With such a structure, the two connected driving bodies 23 and 24, that is, the driving bodies 19 to
22 can be simultaneously formed by one molding die.

As a method of changing the amount of compressive deformation with respect to the pressing force between the corresponding driving bodies, the outer diameter of the driving body may be changed.

Further, another configuration is such that, when the operation knob 18, that is, the operation body 7 is tilted, the two push switches arranged on one side of the swing center axis of the operation body 7 are operated in two steps at different operation strokes. FIG. 16 is a sectional view of a composite switch in which the driving body and the movable contact of the peripheral push switch are changed from the above configuration.

Referring to FIG.
Fourth switch 28 (26, 28 not shown), each driver 25B-28B (26B, 28B not shown)
Are the same specifications formed in the same shape and size with the same elastic insulating material.

However, a circular dome-shaped movable contact 25A of a peripheral push switch, which is provided two on each side of a swing center line which is a line connecting the two support holes 1A of the case 1, is provided.
27A, 26A, 28A (26A, 28A not shown)
Have the same diameter and height, but the elastic metal sheet, which is a material, has a movable contact 27A with respect to the movable contacts 25A and 26A.
And 28A are thicker, and therefore, the reversing operation force when pressed is greater at the movable contacts 27A and 28A.

For this reason, the operating knob 18 and the operating body 7
When the tilt operation is performed, the first switch 25 on the lower surface of the tilt operation side is used.
Alternatively, the third switch 27 or the fourth switch 28 operates in different operation strokes by operating the second switch 26 first and further tilting the operation knob 18.

In this manner, the movable contacts 25A to 25A-2 of the first to fourth switches 25 to 28 in the vicinity are provided.
8A requires two types having different material thicknesses.
Since the cost can be reduced by using only one type of 28B, the cost of the entire composite switch can be reduced.

[0065]

As described above, according to the present invention, a plurality of switches can be individually operated by tilting or pressing one operation unit, and two-stage operation can be performed during the tilting operation. In addition, there is obtained an advantageous effect that a composite switch as an electronic component integrated in advance, which can be operated continuously, can be realized.
