Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a seismic sensor and an outlet with a seismic power breaker that senses vibrations caused by an earthquake, tilting of a house, collapse, etc. to shut off the power supply.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, for example, a small seismic ground fault device as shown in FIG. 9 has been known as a device for cutting off power supply by detecting vibration due to an earthquake or the like, inclination of a house, and collapse.

That is, a plastic pin 111 and an earth pin 112 that are inserted into the insertion ports 301 and 302 of the commercial power outlet 300 are provided on one end side of the case body 110 of the synthetic resin case 100. The socket 120 of the case body 110 is provided with a seismic sensor 200 that senses vibrations such as an earthquake.

The seismic sensor 200 is configured, for example, as shown in FIG. That is, for example, the base portion 250 connected to the ground pin 112 and the clasp 251 connected to the plaque pin 111 are integrally formed.

A suspension wire 222 having a ring portion 223 is attached to the clasp 251 of the mouthpiece portion 250, and the ring portion 221 of the suspension wire 220 is connected to the ring portion 223 via a ring member 224. Further, a pendulum contact 231 is attached to the lower end thereof. In this way, the ring portions 221 and 223 are connected via the ring member 224, so that the pendulum contact 231 can be swung smoothly.

Further, the fixed contact 240 fixed inside the tube portion 210 is connected to the base portion 250 via a lead wire 241.

When the pendulum contact 231 comes into contact with the fixed contact 240 due to vibration or the like, a short circuit is made between the clasp 251 and the base 250, that is, between the plaque pin 111 and the ground pin 112, causing an electric leakage. The operation of the earth leakage breaker connected to the electric wiring inside the house shuts off the supply of commercial power.

[0008]

[Problems to be solved by the device]

 As described above, the above-described conventional seismic leakage device can cut off the supply of commercial power by detecting the vibration due to an earthquake, the inclination of the house, the collapse, etc. by inserting it into the commercial power outlet 300. However, there is an advantage that no new construction is required for installation.

[0009] Furthermore, by sensing the vibration of the seismic leakage device, for example, the operation of an earth leakage breaker in the house shuts off the supply of commercial power to the entire house, which may cause a secondary disaster such as a fire accompanying an earthquake or the like. There is also an advantage that it can be prevented.

However, by cutting off the supply of the commercial power supply to the whole house in this way, there is an advantage that a secondary disaster such as a fire can be prevented in advance, but on the other hand, an earth leakage breaker in the house can be prevented. When it is not possible to recover immediately, there is a problem that you cannot hear information from TV or radio.

On the other hand, in the above-described seismic sensor 200, by connecting the ring parts 223 and 223 via the ring member 224, the pendulum contact 231 can be swung smoothly, for example, When vertical vibration is applied and the pendulum contact 231 vibrates up and down, the ring portion 221 and the ring member 224 or the ring portion 223 and the ring member 224 may be separated for a moment. In such a case, poor contact may occur.

The present invention has been made in response to such a circumstance, and it is possible to surely cut off the power supply in the event of a disaster and also to secure the power supply in necessary places. And to provide an outlet with a seismic power breaker.

[Embodiment of the invention]

 Hereinafter, details of embodiments of the present invention will be described in detail with reference to the drawings. In the drawings described below, parts common to those in FIGS. 9 and 10 are designated by the same reference numerals.

FIG. 1 shows an embodiment of the seismic sensor of the present invention. As shown in the figure, the exterior body 201 of the seismic sensor 200 includes a tube portion 210 and a base portion 250. The tube portion 210 is made of glass, and the tip portion 211 is horizontal, the body portion 212 is cylindrical, and the connection end portion 213 is welding drawn.

The base body 252 of the base 250 is made of a metal material and has a screw cap shape. A spiral groove is formed in the mouthpiece body 252, and a stopper plate 251 is attached to the center portion on the upper end side thereof via an insulating member 253.

Here, the exterior body 201 can manufacture most of the exterior structure of the light bulb by utilizing the manufacturing material, the manufacturing equipment, and the manufacturing technology of the light bulb.

A vibration sensing mechanism 230 is built in the exterior body 201. In the seismic mechanism 230, when the pendulum contact 231 comes into contact with the fixed contact 240, vibration due to an earthquake or the like, inclination of a house, collapse, etc. are detected.

That is, the suspension wire 222 having the ring portion 223 is attached to the clasp 251 of the mouthpiece portion 250. The ring portion 223 of the suspension line 220 is connected to the ring portion 223 via a ring member 224. A pendulum contact 231 is attached to the lower end of the suspension line 220 via a current limiting resistor 232.

The ring portions 221 and 223 and the ring member 224 constitute a relay portion 220A, and the ring portions 221 and 223 are connected via the ring member 224, so that the swinging of the pendulum contact 231 is smoothly performed. It is supposed to be done.

A stranded wire 225 is connected between the upper end of the suspension wire 220 and the lower end of the suspension wire 222. The twisted wire 225 is, for example, a twisted wire of a very fine copper wire. Further, the stranded wire 225 itself does not carry more Joule heat than necessary due to the current limitation by the resistor 232, and is therefore made as thin as possible.

As a result, since the stranded wire 225 has a sufficient flexibility as compared with a single wire, an unnecessary tensile force may be applied between the upper end portion of the hanging wire 220 and the lower end portion of the hanging wire 222. Therefore, the pendulum movement of the pendulum contact 231 can be performed without any trouble.

Although the stranded wire 225 is used in this example, a conductive wire other than the stranded wire may be used in some cases.

The fixed contact 240 is formed of a conductive metal material in a cylindrical shape, and is fixed to the inner surface of the tube portion 210 by fitting or glass welding. Further, the fixed contact 240 is connected to the base 250 through a lead wire 241.

Next, the operation of the seismic sensor 200 having the above configuration will be described. First, in the seismic sensor 200, a set value to be reacted in advance is set so as not to excessively react to a weak vibration or the like. Incidentally, this set value is adjusted by the lengths of the suspension lines 220 and 222, the ratio of the mutual diameters of the pendulum contact 231 and the fixed contact 240, and the diameter of the pendulum contact 231.

When the seismic sensor 200 is used, for example, when it is used in an outlet 400 with seismic power circuit breaker shown in FIGS. 2 to 4 described later, the stopper 251 is, for example, one end side of the current sensing coil 403. The base body 252 is connected to the other end side of the current sensing coil 403 via the amplifier 404, for example. When the seismic sensor 200 is placed vertically, the pendulum contact 231 is located at the center of the tube portion 210.

In this state, when vibration or the like exceeding the above-mentioned set value is applied to the seismic sensor 200, the pendulum contact 231 makes a pendulum motion. At this time, the ring portion 221 of the suspension wire 220 supporting the pendulum contact 231 is point-contact supported to the ring member 224, and the resistor 232 has a cylindrical shape. Since the weight balance of the state is made uniform, the pendulum contact 231 does not make an irregular pendulum motion, but makes a regular motion in any vibration direction of 360 degrees.

At this time, the stranded wire 225 connected between the upper end of the suspension wire 220 and the lower end of the suspension wire 222 is as thin as possible and has sufficient flexibility as described above. Therefore, the pendulum contact 231 does not cause an irregular pendulum motion.

When the pendulum contact 231 comes into contact with the fixed contact 240 due to the pendulum motion, a current flows between the pendulum contact 231 and the fixed contact 240, so that vibration or the like is detected.

Further, vertical vibration is applied to the seismic sensor 200, and the pendulum contact 231 vibrates up and down, so that it is between the ring portion 221 and the ring member 224, or between the ring portion 223 and the ring member 223. Even if the member 224 and the member 224 are momentarily separated from each other, the stranded wire 220 connected between the upper end of the suspension wire 220 and the lower end of the suspension wire 222 maintains the continuity of the suspension wires 220, 222. Therefore, it is possible to reliably detect vibrations.

As described above, in this embodiment, when the pendulum contact 231 makes a pendulum motion due to vertical vibration, for example, the ring portions 221 and 223 of the relay portion 220A and the ring member 224 are momentarily separated from each other. Even if contact failure occurs, both ends of the relay portion 220A are electrically connected by the fine stranded wire 225, so contact failure is avoided, and vibration due to contact between the pendulum contact 231 and the fixed contact 240, etc. Is reliably detected.

FIGS. 2 and 3 show an embodiment of an outlet with a seismic power circuit breaker according to the present invention. Further, in this embodiment, the above-described seismic sensor 200 is incorporated.

As shown in these figures, a cover plate 402 is attached to the front side of the outlet body 401 of the outlet 400 with seismic power circuit breaker. The cover plate 402 is fixed to the outlet body 401 by, for example, a bolt (not shown) attached from the front side of the outlet body 401.

On the left half side of the cover plate 402, two auxiliary outlets 410 each having an insertion port 411 are provided.

It should be noted that the number of these auxiliary outlets 410 is not limited to two, and may be one or three or more. Further, these auxiliary outlets 410 are not limited to the cover plate 402, and may be provided on the upper, lower, left and right side surfaces of the outlet main body 401.

At the center of the right half of the cover plate 402, a breaker lever 420 of a breaker 420A described later is arranged so as to be rotatable in the arrow direction. Below the breaker lever 420, a test button switch 421 for testing the operation of the outlet main body 401 is arranged.

The breaker lever 420 and the test button switch 421 are covered by a protective cover 430 having operation holes 432 on both sides. Further, a small hole 431 into which a thin toothpick-shaped member can be inserted is formed in a portion of the protective cover 430 corresponding to the test button switch 421.

The protective cover 430 is made of a transparent or translucent resin or the like, and makes it easy to recognize the position of the breaker lever 420. Further, since the breaker lever 420 is covered with the protective cover 430, the erroneous operation of the breaker lever 420 is prevented.

That is, when the seismic-sensing power breaker-equipped outlet 400 is used at home, for example, the plaque pin 440 provided on the back side of the breaker lever 420 is used by mounting it on a wall outlet. Since it is installed about 20 cm above the floor, it will be installed within the reach of everyday life. In this case, there is a risk of being misled by an infant or the like, but the protective cover 430 protects the breaker lever 420 from erroneous operation.

FIG. 4 is a connection diagram of an outlet 400 with a seismic power circuit breaker. As shown in the figure, the commercial power input obtained through the plaque pin 440 is supplied to the auxiliary outlet 410 side through the breaker lever 420 of the earth leakage breaker 420A and the lines 401a and 401b.

A current sensing coil 403 is arranged near the breaker lever 420, and the breaker lever 420 is turned off by operating an amplifier 404, which will be described later, by sensing the current by the current sensing coil 403. ing.

One end of the current sensing coil 403 is connected to a clasp 251 that is electrically connected to the suspension lines 220 and 222 of the base 250 of the seismic sensor 200 via a line 402a. The other end of the current sensing coil 403 is connected to the base body 252 via the amplifier 404 and the line 402b.

The test button switch 421 is interposed between one end of the current sensing coil 403 and the other end via the amplifier 404. When the test button switch 421 is turned on, the current sensing coil 403 is driven and the breaker lever 420 is turned off, so that the operation test can be performed.

Next, the operation of the seismic-sensitive power breaker-equipped outlet 400 configured as described above will be described.

First, when the outlet body 401 of the seismic-sensitive power circuit breaker outlet 400 is used at home, for example, the plaque pin 440 is inserted into the outlet 301 of the commercial power outlet 300 shown in FIG.

Next, a plug of an electric stove or an electric appliance such as a television is inserted into the insertion port 411 of the auxiliary outlet 410 of the outlet main body 401. At this time, when the contact of the breaker lever 420 is closed, as shown in FIG. 4, the electric power from the commercial power source is supplied to the electric appliance through the lines 401a and 401b inside the outlet main body 401 and the auxiliary outlet 410. Made possible.

At this time, since the seismic sensor 200 is maintained vertically inside the outlet main body 401, the contact between the pendulum contact 231 and the fixed contact 240 is avoided as described above.

In this state, when performing an operation test of the outlet main body 401, a toothpick-shaped thin member is inserted from the small hole 431 of the protection cover 430 and the test button switch 421 is pressed. As a result, the lines 402a and 402b connected to the above-described current sensing coil 403 are closed, and the breaker lever 420 is turned off by the operation of the current sensing coil 403, so that normal operation can be confirmed.

After confirming the normal operation of the outlet main body 401, the breaker lever 420 is restored. In this case, power can be supplied from the outlet main body 401 by inserting a finger from one of the operation holes 432 on both sides of the protective cover 430 and returning the breaker lever 420 to the home position.

On the other hand, when a vibration or the like exceeding the set value is applied to the seismic sensor 200, the pendulum contact 231 makes a pendulum motion. At this time, the ring portion 221 of the suspension wire 220 supporting the pendulum contact 231 is point-contact supported to the ring member 224, and the resistor 232 has a columnar shape, and the suspension wire 220 suspends the suspension wire 220. Since the weight balance in the lowered state is uniform, the pendulum contact 231 does not make an irregular pendulum motion, but makes a regular motion in any vibration direction of 360 degrees.

At this time, the stranded wire 225 connected between the upper end of the suspension wire 220 and the lower end of the suspension wire 222 is as thin as possible and has sufficient flexibility as described above. Therefore, the pendulum contact 231 is prevented from performing an irregular pendulum motion.

When the pendulum contact 231 comes into contact with the fixed contact 240 due to the pendulum motion, a current flows between the pendulum contact 231 and the fixed contact 240, and the breaker lever 420 is turned off by the operation of the current sensing coil 403. As a result, the supply of commercial power from the auxiliary power supply 410 is cut off.

At this time, vertical vibration is applied to the seismic sensor 200, and the pendulum contact 231 vibrates up and down, so that the ring portion 221 and the ring member 224 or the ring portion 223 and the ring member 224 are vibrated. Even if the member 224 is separated from the member 224 for a moment, the stranded wire 225 connected between the upper end of the hanging wire 220 and the lower end of the hanging wire 222 maintains the electrical continuity of the hanging wires 220, 222. Therefore, the breaker lever 420 is turned off by the operation of the current sensing coil 403, and the supply of commercial power from the auxiliary outlet 410 is surely cut off.

As described above, in this embodiment, the seismic sensor 200 and the earth leakage breaker 420A are housed in the outlet body 401, and the earth leakage breaker 420A is automatically shut off by the detection of the seismic sensor 200. In addition, by returning the breaker lever 420 provided on the main body 401 of the outlet to the fixed position, electric power can be immediately obtained, so that information from a television, a radio, or the like can be heard.

FIG. 5 shows another embodiment in which the configuration of the outlet 400 with seismic power circuit breaker shown in FIGS. 2 and 3 is modified. In the drawings described below, parts common to those in FIGS.

The figure shows a form in which an insertion plug is extended through a plug cord.

That is, the outlet body 401A of the seismic power circuit breaker-equipped outlet 400A has an elongated cubic shape. The breaker lever 420 and the test button switch 421 described above are provided on the upper surface side of the outlet main body 401A. The breaker lever 420 and the test button switch 421 are covered with the above-mentioned protective cover 430.

Further, a plug cord 442 is pulled out from the vicinity of the protective cover 430 on the upper surface side of the outlet main body 401A. The plug cord 442 can be pulled out from any position, not limited to the vicinity of the protective cover 430.

A plug plug 441 having a plaque pin 440 is provided at the tip of the plug cord 442. As a result, when the outlet main body 401A is used, both a wall outlet and a floor outlet can be used.

An auxiliary outlet 410 having the above-mentioned insertion port 411 is provided on the front side surface of the outlet main body 401A. The auxiliary outlet 410 can be provided not only on the front side surface but also on the left and right side surfaces, and the number thereof may be two or more.

Further, the seismic sensor 200 described above is built in the inside of the outlet main body 401A. Further, the connection state of the outlet main body 401A is substantially the same as that in FIG.

The seismic-sensitive power breaker-equipped outlet 400 having such a configuration is used as follows.

First, since the insertion plug 441 of the outlet main body 401A is extended through the plug cord 442, it can be used as a wall outlet or a floor outlet as described above.

Then, for example, when a floor outlet is used, the plug pin 440 of the insertion plug 441 is inserted into the insertion port (not shown) of the floor outlet, and the outlet main body 401A is placed on the floor or the like. In this case, since the lower surface side of the outlet main body 401A is a flat plate, the outlet main body 401A can be installed in a stable state.

When the operation test of the outlet main body 401A is performed after the installation of the outlet main body 401A is completed, as described above, a toothpick-shaped thin member is inserted from the small hole 431 of the protective cover 430 and the test button is pressed. The switch 421 is turned on.

After confirming that the operation of the outlet main body 401A is normal, a finger is inserted from one side of the protective cover 430 to return the breaker lever 420 to the normal position in the same manner as above.

When vibration or the like exceeding the set value is applied to the seismic sensor 200, the pendulum contact 231 contacts the fixed contact 240 due to the pendulum motion, and the breaker lever 403 operates due to the operation of the current sensing coil 403. When 420 is turned off, the supply of commercial power source power via the auxiliary socket 410 is cut off.

At this time, when the vertical vibration is applied to the outlet main body 401A, as described above, the twisted line 225 is provided between the upper end of the suspension line 220 and the lower end of the suspension line 222. Since it is connected, there is no malfunction due to poor contact, and the power is shut down normally.

Therefore, in this embodiment, since the insertion plug 441 extends from the outlet main body 401A via the plug cord 442, both a wall outlet and a floor outlet can be used.

It is like this.

The breaker lever 420 and the test button switch 421 described above are provided on the mounting plate 405a. Further, the breaker lever 420 and the test button switch 421 are covered with the above-mentioned protective cover 430.

Further, the cover plate 405 is provided with two auxiliary containers 410 having the above-mentioned insertion port 411. Here, the number of these auxiliary outlets 410 is not limited to two, and may be one, or may be three or more.

Inside the outlet main body 401B, a socket 450 for mounting the seismic sensor 200 and an earth leakage breaker 422 are provided.

An input line 460 of a commercial power source is connected to the earth leakage breaker 422. The output of the commercial power source via the earth leakage breaker 422 is connected to each auxiliary outlet 410 via a line 461. Furthermore, the socket 450 and the earth leakage breaker 422 are connected via a line 462.

[0112] The seismic power interrupter-equipped outlet 400B having such a configuration is used as follows.

First, the input line 460 of the commercial power source is drawn out from the opening 501 opened in the wall 500 during electrical work, and its end is connected to a predetermined portion of the earth leakage breaker 422.

After the connection of the input line 460 is completed, the main body 401B of the cover is pushed against the opening 501 of the wall 500 until the back side of the mounting plate 405a of the cover plate 405 is pressed against the outer periphery of the opening 501. Put in.

At this time, the back surface side of the mounting plate 405a of the cover plate 405 is pressed against the outer peripheral portion of the opening portion 501, and the opening portion 501 is blindfolded, so that the mounting finish is neat.

When the operation test of the outlet main body 401B is performed after the mounting of the seismic-sensitive power circuit breaker outlet 400B and the contact of the breaker lever 420 are closed, as described above, the small hole 431 of the protective cover 430 is used. Then, a toothpick-shaped thin member is inserted to turn on the test button switch 421.

After confirming that the operation of the outlet main body 401B is normal, a finger is inserted from one side of the protective cover 430 to return the breaker lever 420 to the normal position in the same manner as above.

When a vibration exceeding the set value is applied to the seismic sensor 200, the pendulum contact 231 contacts the fixed contact 240 due to the pendulum motion, and the breaker lever 420 operates due to the operation of the current sensing coil 403. Is turned off, and the supply of commercial power from the auxiliary outlet 410 is cut off.

At this time, even when the vertical vibration is applied to the outlet body 401A, as described above, the twisted line 225 is provided between the upper end of the suspension line 220 and the lower end of the suspension line 222. Since it is connected by, there is no malfunction due to poor contact, and the power is shut down normally.

Therefore, in this embodiment, when the outlet main body 401B is pushed into the opening 501, which is a wall hole that is opened in the wall during electrical work, the back side of the mounting plate 405a of the cover plate 405 is opened. Since it is pressed around the portion 501, the opening 50 is blindfolded, and the finish of mounting is neat.
