This is a vibration detection switch.

The electric tilt switch described in Japanese Patent Application Laid-Open No. 62-103931 is a tilt vibration switch in which a ball bearing is sandwiched between an upper cap and a concave lower base. When the bearing contacts only the base and tilts, the bearing contacts the upper cap at a predetermined angle.

The tilt switch described in Japanese Patent Application Laid-Open No. Sho 62-55842 has a through hole provided in a conical bottom surface, a push button bar is disposed in the through hole, and the push button bar is protruded from the push button bar by a spring. This is a switch having a structure in which the push button rod is pressed by a ball bowled on the bottom surface so that the push button rod does not rise rapidly.

In the switch mechanism described in Japanese Patent Application Laid-Open No. 1-152426, a fixed contact is provided on a substrate, a slope is formed on an upper portion by a vertical slider and a horizontal slider, and the slope is expanded and contracted by a spring to contact a sphere. , A switch mechanism using a spherical movable contact.

[0015]

The problems of the above-mentioned prior art are listed below.

First, a vibration detecting device of a portable alarm described in Japanese Patent Application Laid-Open No. 61-180392 is composed of a linearly extending wire, a metal ball, and an outer wall.
Since the metal sphere moves along the radial line, when the metal sphere comes into contact between the line and the outer wall, the metal sphere conducts to sense vibration. However, the metal object should be able to move freely if the vibrations, which is the original purpose, are to be detected. In the state where it is supported by, and when there is vibration, it is initially in a state where it is supported by the above-mentioned linear body and the outer wall, and when there is no vibration, it is also a structure that returns to the supported state, Vibrations that are too weak to leave the supported state cannot be detected. Therefore, when the vibration is weak, the metal sphere is supported by the radially arranged wires, so that the metal body is kept in contact with the outer wall and the vibration cannot be detected.

The vibration detection switch described in Japanese Patent Application Laid-Open No. 59-60835 is a vibration detection switch using a magnet, and is wrapped in a magnetic material from a recess in the center of the inverted conical bottom surface by vibrations such as earthquakes. The ball pops out, is absorbed by the annular magnet on the side wall of the inverted cone, and has a structure for conducting between the inverted cone and the side wall. By manually lifting the annular magnet, the ball returns to the original depression in the center of the bottom surface of the inverted cone. However, it does not return to the recess at the center of the inverted conical bottom surface due to vibration. In addition, if the vibration detection switch itself is tilted other than the vibration, the ball is absorbed by the annular magnet on the side wall, and a linear motion occurs. This vibration detection switch is intended to detect an earthquake or the like, and needs to be manually released once the switch is turned on.

With respect to the electric tilt switch described in Japanese Patent Application Laid-Open No. Sho 62-103931, a ball bearing is sandwiched between an upper cap and a concave dish-shaped lower part, and the ball bearing moves from the center of the concave dish-shaped lower part. When the upper cap and the concave dish-shaped lower part come into contact with each other and become conductive, the inclination is output. However, the electrical tilt switch cannot detect the signal unless the switch is tilted by a certain angle or more. Therefore, it is impossible to detect vibration or reaction.

The tilt switch described in Japanese Patent Application Laid-Open No. H4-249019 is a tilt switch having a conical inner wall of a casing. When the tilt switch is tilted, the sphere moves from the conical bottom surface of the inner wall of the casing and comes into contact between the wall surface and the conical bottom surface. However, it is impossible to detect the tilt switch unless the tilt switch tilts more than a certain degree.

The encapsulation switch described in Japanese Patent Application Laid-Open No. Sho 62-165822 is a switch that detects vibration and inclination with a conductive sphere that moves in a space between an upper contact and a lower mortar-shaped contact. When the enclosing switch is tilted or vibrated, the conductive sphere protruding from the lower mortar-shaped contact contacts the upper contact and conducts to output vibration or tilt. However, the enclosed switch cannot be detected unless it is tilted or vibrated to some extent. That is, it is impossible to detect a weak vibration or a recoil.

The fall / vibration switch described in Japanese Patent Application Laid-Open No. 6-52763 is a switch that falls and vibrates with a sphere moving in a space surrounded by an upper body and a lower terminal plate. However, the fall / vibration switch cannot be detected unless the inclination or vibration is applied to a certain degree or more. Therefore, it is impossible to detect a weak vibration or reaction.

The cylindrical position detecting switch described in Japanese Patent Application Laid-Open No. 61-42043 is a switch that detects a position by conducting a conductive sphere with a contact provided in a depression of a cylindrical container. However, the cylindrical position detection switch detects the position by conducting to the electrode at the bottom of the recess when a conductive ball enters the recess. for that reason,
Since the position is detected depending on whether or not there is conduction, only two states can be detected.

The rollover high impact detection device for a vehicle described in Japanese Patent Application Laid-Open No. 58-189930 is a device for shutting off a power supply system circuit when the vehicle is overturned or receives a strong impact due to an accident. The sphere has a structure in which the switch detects a roll when the vehicle rolls over, and a horizontal acceleration sensing member detects the switch by pressing the switch when a strong impact is applied. However, since the vehicle rollover high impact detection device is intended to cut off the power supply circuit in the event of an accident, it has a structure that cannot be used repeatedly once an impact is applied.

The tilt switch described in Japanese Utility Model Laid-Open Publication No. 4-112436 detects a sphere with a photosensor or a switch at the bottom of a cone and detects that the sphere is tilted by the movement of the sphere due to the tilt. However, similarly to the example described in the above-mentioned Japanese Patent Application Laid-Open No. 61-42043, this tilt switch detects the position depending on whether or not there is conduction, so that only two states can be detected.

The tilt switch described in Japanese Patent Application Laid-Open No. Sho 62-55842 is a switch having a structure in which a pushbutton is provided on a conical bottom surface, and when the sphere is not on the conical bottom surface, the pushbutton bar does not rise rapidly. However, this is also disclosed in the above-mentioned JP-A-61-4.
Similarly to the switch described in Japanese Patent No. 2043, the position is detected based on whether or not there is conduction, so that only two states can be detected.

The inclined contact point described in Japanese Patent Application Laid-Open No. 57-189421 is composed of a conical light bulb and a donut-shaped current-carrying element. This is disclosed in the above-mentioned JP-A-61-180.
As with the vibration sensing device of the portable alarm described in Japanese Patent Publication No. 392, a structure that returns to a supported state cannot detect weak vibrations that cannot be separated from the supported state.

The vibration sensor described in Japanese Patent Application Laid-Open No. 61-187621 has a plurality of pillars having a conductive portion and an insulating portion, and a conductive member capable of freely moving to a portion surrounded by the plurality of pillars. This is a vibration sensor composed of a sphere. However, when the vibration sensor is in a conductive or non-conductive state due to the inclination, even if the conductive sphere moves by vibration, the conductive sphere remains in contact with the column member, and it is impossible to detect the conductive or non-conductive state.

The switch mechanism described in JP-A-1-152426 is a switch using a spherical movable contact. However, this example differs from the present invention in structure and purpose only because the sphere is a movable contact.

As described above, in the conventional example, there is a problem that the movement of the metal sphere is limited, and it is difficult to detect it by a weak vibration or a recoil.

Accordingly, an object of the present invention is to solve the above-mentioned problems in the prior art by vibrating the metal sphere freely by minimizing the vertical and vertical movements as much as possible. It is an object of the present invention to provide a tilt vibration switch which performs reliable operation detection regardless of the strength of tilt, recoil and recoil.

[0031]

SUMMARY OF THE INVENTION The object of the present invention is to provide a switch according to the present invention, that is, a cylindrical case having both ends opened and a cylindrical case.
A pair of bases covering both ends of the case and having four holes each
Penetrate the board and four holes each to almost the same depth.
Four conductive pins each having the same length and four conductive pins each
Contacting at least two of the conductive pins
And a conductive sphere as a contact point, penetrating through one of the substrates
Four conductive pins are connected to the four conductive pins
Four conductive pins are opposed to the conductive pins, and each of the four conductive pins is
Are arranged to form a substantially square, and
The length of one side is almost equal to the distance between the conductive pins facing each other.
Smaller than the diameter of the conductive sphere, and
Arrange the wire so that its length is larger than the diameter of the conductive sphere.
When the cylindrical case vibrates and reacts, the electrical contacts move.
By repeating conduction and non-conduction when moving , motion detection of the motion detection target is performed continuously and in all directions.

Also, when the case is rotated, the conductive sphere may have a contact with any one of the plurality of conductive pins. Furthermore, when the conductive sphere contacts a plurality of conductive pins, the pins may be electrically connected. Further, it is more preferable that the conductive sphere moves and repeats conduction and non-conduction to continuously detect vibration, tilt, and recoil. More preferably, the shape of the case is cylindrical. Further, the number of conductive pins is preferably four for each substrate.

According to the tilt vibration switch of the present invention, by adjusting the interval between the conductive pins supporting the conductive sphere,
A moving object such as a sphere is built in to detect vibration, tilt, and recoil of the motion detection target because of the structure that allows sensitivity adjustment. Then, by detecting whether or not there is a moving object at a certain position, movement due to vibration, tilt, and recoil is detected as conduction or non-conduction, so only when the motion detection target is operating Will be detected. This makes it possible to detect horizontal vibration, tilt, and recoil in addition to vertical vibration, tilt, and recoil. Further, even if the tilt vibration switches are in the same posture, it is possible to detect the vibration, tilt, and recoil of the motion detection target with a single device.

The tilt vibration switch of the present invention has a structure in which the sensitivity can be adjusted by adjusting the interval between the conductive pins that support the conductive sphere.
The conduction is detected only when the conductive sphere moves inside the cylindrical shape due to the inclination and reaction, and the conductive sphere contacts between the conductive pins. When the tilt vibration switch is vertical and vibration, tilt, and recoil are applied in the horizontal direction, the conductive sphere moves in the horizontal direction from the normal position.
At this time, the conductive sphere jumping out of the normal position is separated from the support position of the conductive pin and becomes non-conductive. Then, when an even greater vibration or inclination is applied, the conductive sphere negotiates with the upper substrate.

The same conductive pins as those of the upper substrate are arranged on the lower substrate of the tilt vibration switch according to the present invention, and the conductive pins of the upper substrate and the lower substrate are conductive even when they contact. become. Even if circumferential rotation is applied to the tilt vibration switch, the conductive sphere repeatedly conducts and non-conducts with the conductive pins of the upper substrate and the lower substrate.
Furthermore, even if the tilt vibration switch is tilted beyond a certain angle,
In other words, even if the tilt vibration switch is in a horizontal state or a state in which it rotates vertically, the same conductive pins are arranged on the upper substrate and the lower substrate, so that tilt, vibration, and recoil in any direction are possible. Can be detected.

The advantages of the tilt vibration switch of the present invention have been described above.
Since it is composed of the conductive pin, the conductive sphere, and the case, the size, weight, and productivity can be improved. Furthermore, no power supply is required due to the mechanical switch structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the tilt vibration switch according to the present invention will be described with reference to the drawings.

FIG. 1 is an external view showing a tilt vibration switch according to the present invention. There are lids above and below the cylindrical case 4, and disc-shaped substrates 2a and 2b are provided on the upper and lower lids.
Four concentric holes are formed in the substrates 2a and 2b, and pins 1a and 1b are inserted into the holes. These substrates 2a, 2b
And the pins 1a and 1b constitute a lid portion.
b is insulating and pins 1a and 1b are conductive.

FIG. 2 is a perspective view showing a lid portion of the tilt vibration switch of the present invention, and is a diagram showing one of the upper and lower lid portions. Four conductive pins 1a are inserted into one insulating substrate 2a. In this embodiment, the number of pins is four.
, But if necessary, more, for example, 8, 16
It can be individual.

FIG. 3 is a sectional view when the tilt vibration switch of the present invention is in a vertical state. It comprises an upper substrate 2a, a lower substrate 2b, a conductive pin 2b, a conductive pin 1a, a conductive pin 1b, and a conductive sphere 3, and the conductive sphere 3 is placed in a cylindrical case. Arrangement of conductive pins 1a and 1b
The relationship between the position and the conductive sphere will be described.
The four conductive pins 1a and 1b face each other,
And four conductive pins 1a (1b) form a substantially square
And the length of one side of the square is 1
Of the opposing conductive pins 1a, 1b of the pair of substrates 2a, 2b.
Approximately equal to the distance, smaller than the diameter of the conductive sphere 3,
In addition, the length of the square diagonal line is equal to the diameter of the conductive sphere 3.
Are arranged so as to be larger. Thus, even when the tilt vibration switch is rotated in the circumferential direction, the conductive sphere repeats conduction and non-conduction with the conductive pins of the upper substrate and the lower substrate. Furthermore, even if the tilt vibration switch is tilted by a certain angle or more, that is, the tilt vibration switch becomes horizontal or turns up and down, the upper substrate,
Since similar conductive pins are arranged on the lower substrate,
Inclination, vibration, and recoil in any direction can be detected.

Next, vibration detection of the tilt vibration switch of the present invention will be described with reference to FIG. When vibration is applied to the tilt vibration switch, the conductive sphere 3 jumps out of the state in which the conductive pins 1b of the lower substrate 2b are supported, separates from the conductive pins 1b of the lower substrate 2b, and becomes non-conductive. When the vibration is eliminated, the conductive sphere 3 returns to the original normal position, and the conductive sphere 3 and the conductive pin 1 on the lower substrate 2b are again returned.
It conducts with b. However, when a larger vibration is applied, the conductive sphere 3 leaves the state where the conductive pins 1b of the lower substrate 2b are supported, and the conductive spheres 3 of the upper substrate 2a.
a. Therefore, the conductive pins 1a of the upper substrate 2a
And the conductive pins 1b of the lower substrate 2b are brought into contact with each other, thereby establishing a conductive state therebetween. Vibration detection is performed by repeating this conduction and non-conduction.

Next, the tilt detection of the tilt vibration switch of the present invention will be described with reference to FIG. FIG. 4 is a cross-sectional view illustrating a state where the tilt vibration switch is tilted.
When the tilt vibration switch itself is tilted by a certain angle or more, the conductive sphere 3 enters between the conductive pin 1a of the upper substrate 2a and the conductive pin 1b of the lower substrate 2b, and the state becomes as if it has fallen into a groove. Stabilize. At this time, when circumferential rotation is applied to the tilt vibration switch, the conductive spheres 3 are connected to the conductive pins 1a of the upper substrate 2a and the conductive pins 1a of the lower substrate 2b.
The conductive and non-conductive states are repeated by moving in the groove between the first and second b. Therefore, even if the tilt vibration switch is tilted more than a certain angle (Φ) and the tilt vibration switch is turned over, the upper substrate 2a and the lower substrate 2
Similarly, since the conductive pins 1a and 1b are arranged in b, it is possible to detect any inclination or vibration in any direction. Thus, inclination detection is performed.

FIG. 5 is a cross-sectional view showing a state in which the tilt of the tilt vibration switch of the present invention is in a horizontal state in an extreme example. Also in this case, the conductive pins 1a of the upper substrate 2a and
The conductive sphere 3 is connected between the conductive pin 1b of the lower substrate 2b and the conductive pin 1a and the conductive pin 1b.

[0044]

As described above, according to the tilt vibration switch of the present invention, the pattern A in which the conductive sphere 3 inside the tilt vibration switch is made of a conductive substance due to the vibration, tilt, and recoil of the operation detection object (for example, connection The circuit is mechanically opened and closed by contacting both points with the conductive pin 1a) and the pattern B (for example, when one of the connection points is the conductive pin 1a and the other is the conductive pin 1b). And therefore,
The operation detection of the operation detection target can be performed without supplying power from the outside. Further, since it is not necessary to prepare a power supply circuit for the tilt vibration switch, the peripheral circuits can be simplified.

Further, since the tilt vibration switch of the present invention has contacts in all directions around the conductive sphere 3, 36
That is, motion detection in all directions of 0 ° is performed. Thus, the operation can be detected regardless of the direction of the switch.

Furthermore, since there are a total of 12 parts, two substrates, one case, one conductive sphere, and eight conductive pins, the number of parts is small and assembly is easy. .
