In order to prevent the ring), a circuit is required and the cost increases. There were problems such as. Inclination / vibration switches using mercury are prone to malfunction due to expansion of mercury due to temperature changes. Since it does not operate with minute vibrations, it has low operation sensitivity. Mass production is difficult because it is produced manually. Since mercury is used, it is dangerous for the human body when it is damaged, and it also causes social problems because it pollutes the environment. Slow vibrations are not detected. Since soldering is required for lead wires, etc., automatic solder mounting is impossible. Because it uses mercury and glass, it is expensive and easily damaged. It is difficult to miniaturize. In order to prevent chattering, a circuit is required, which increases the cost. There were problems such as. In addition, even in the tilt / vibration switch as described above using a sphere, since it generally has a large number of parts and has a complicated structure, it is not only prone to failure, but also has a difficulty in terms of manufacturing cost. Due to the shape and the terminals led to the outside, downsizing and mass production were difficult.

[0006]

When the conductive sphere is placed in the concave portion of the projection formed on the second electrode, the conductive sphere does not contact the first electrode, and thus is in the off state. In such an off state, when the tilt / vibration switch is externally vibrated vertically or horizontally, or when the tilt / vibration switch is tilted, the conductive sphere contacts the first electrode. Therefore, the inclination and the vibration can be detected. On the other hand, when the conductive sphere is in contact with the first electrode, the conductive sphere and the second electrode are not in contact with each other, and thus the state is off. In such an off state, when the switch is externally vibrated vertically or horizontally, or when the switch is tilted, the conductive sphere comes into contact with the second electrode, so that the switch is turned on and therefore the tilt and Vibration can be detected.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the tilt / vibration switch of the present invention will be described with reference to the drawings. 1 to 3
Shows the switch 20 in a vertical position. Among these drawings, FIG. 1 is an external view, FIG. 2 is a vertical sectional view showing an off state, and FIG. 3 is a vertical sectional view showing an on state. . In these drawings, the first mounting member 21 of the tilt / vibration switch 20 is made of an insulating member such as plastic in the shape of a housing, and inside the mounting member 21, a tilted surface 21A of about 10 degrees is formed. Has been done. A second mounting member 22 is mounted on the mounting member 21, and the second mounting member 22 has a concave mounting portion 22A having an inclined surface of about 10 degrees.

The first mounting member 21 is provided with a conductive member 23A made of aluminum vapor deposited and a conductive member 23B made of a copper plate, and the second mounting member 22 is made of aluminum. A conductive member 24A configured by vapor deposition of the night and a conductive member 24B configured by a copper plate or the like are provided. A conductive sphere 25 made of a bearing or the like is housed in a housing formed of the first mounting member 21 and the second mounting member 22. A non-conductive plastic material is used for the first mounting member 21 and the second mounting member 22, and a conductive plastic material is used for the conductive member 23A and the conductive member 24A. The material and the conductive plastic material can be integrally molded with a molding die. Further, as in the present embodiment, the conductive member 23A
Further, the conductive member 24A may be provided with other conductive members such as conductive plastic, copper wire and iron wire instead of being formed by vapor deposition of aluminum foil. In the tilt / vibration switch having the above-described configuration, the conductive sphere 25 has the second mounting member 2
When mounted on the second concave mounting portion 22A, the conductive sphere 25 abuts only on the conductive member 24A arranged on the second mounting member 22, as shown in FIG. Since it does not come into contact with the conductive member 23A disposed in the above, it is in an off state because electricity is not energized. In such an OFF state, if the tilt / vibration switch 20 is externally vibrated vertically or horizontally, or if the tilt / vibration switch 20 tilts, the tilt / vibration switch 20 moves as shown in FIG. Since the conductive member 23A disposed in 21 also comes into contact with the conductive member 23A, it is in an ON state, and tilt and vibration are detected. In this case, since the first mounting member 11 and the second mounting member are cylindrical and the entire shape of the tilt / vibration switch 20 is cylindrical, vibration or tilt in all directions is detected. By the way, since the second mounting member 22 is provided with the concave mounting portion 22A of about 10 degrees, it absorbs unnecessary vibration. In addition, in the present embodiment, the inclined surface of the concave mounting portion 22A is about 10 degrees, but the angle of this inclined surface is arbitrarily set according to the strength of vibration.

In these figures, the first electrode 41 formed in the housing shape of the tilt / vibration switch 40 has a tilted surface 41A of about 40 degrees. A ring-shaped insulating member 42 is attached inside the first electrode 41. A second electrode 43 having an inclined surface 43A is attached to the insulating member 42. The second electrode 43 is attached to the first electrode 41 so that a void 44 is formed. Therefore, since the first electrode 41 and the second electrode 43 are not in contact with each other, the first electrode 41
Since the second electrode 43 is not connected to the second electrode 43, it is in an off state because electricity is not supplied. The housing composed of the first electrode 41, the insulating member 42, and the second electrode 43 includes a conductive moving member 45 including a spherical bearing.
Is housed. In addition, 46 shows a horizontal line. In the above-described second embodiment, as shown in FIG. 5, the conductive moving member 45 contacts only the inclined surface 43A of the second electrode 43, so that the first electrode 41 and the second electrode 43 do not contact each other. It is in an off state because electricity is not applied due to conduction. When the tilt / vibration switch 40 is tilted by 70 degrees in such an off state, as shown in the explanatory view showing the principle of switching from the off state to the on state in FIG. 41A of the inclined surface formed on the first electrode 41
Since the first electrode 41 and the second electrode 43 are electrically connected to each other, the inclination is detected. Further, since the first electrode 41 and the second electrode 43 are cylindrical and the tilt / vibration switch 40 is formed in a cylindrical shape as a whole, tilts in all directions are detected. Further, the inclination angle D and the inclination angle of the inclined surface 43A of the second electrode 43 are arbitrarily adjusted within the range of 5 degrees to 90 degrees according to the application.

[0009]

Since the present invention is constructed as described above, according to it, the number of parts is small, the construction is simple and durable, the cost can be reduced, the size can be reduced, and the mass production can be performed. It is good in terms of responsiveness and reliability, and has anti-theft devices, toys, precision machines, game machines, measuring instruments, vibration detection devices for industrial machinery, accessories, household overturn detection devices, home appliances, hobby products, and security devices. It is possible to obtain a tilt / vibration switch that can be used for various large and small devices such as electronic wrist watches.
