Description

  The present invention relates to a seismic sensor that senses vibrations such as earthquakes, an outlet for responding to an abnormality, and a wiring system using the outlet for responding to an abnormality.

  In Japan, an earthquake-prone country, many damages have been caused by earthquakes. One example is the Great Hanshin-Awaji Earthquake that occurred on January 17, 1995. The earthquake has lost about 6,400 lives. This earthquake caused fires at many points. It is said that this fire occurred more often when the subsequent power supply resumed than immediately after the earthquake. In many cases, an electric heater or an electric appliance having a heat generating part that is connected to an outlet is pressed by furniture or is sandwiched between household items. In this state, some electrical products have their own power supply, and some electrical products did not work well under an abnormal situation when the safety switch in the event of a fall. Under such circumstances, when electric power supply resumes after a while since the occurrence of the earthquake, these electric products generate heat and cause a fire. As households are widely electrified, it is extremely important to ensure the safety of electrical products in the event of such an earthquake.

  Therefore, a technique for detecting the shaking when an earthquake occurs and cutting off the power supply to the wiring device attached to the wall-embedded outlet has been proposed as the first related technique of the present invention. (For example, Patent Document 1). The wiring device according to the first related technology uses the electric product through the plug inserted into an outlet. When the vibration detector in the wiring device senses vibration in this state of use, the earthquake determination unit in the wiring device also determines the earthquake by removing the daily vibration. This wiring device is provided with a cutoff circuit that cuts off the power of the electrical product supplied from the plug when the earthquake judgment unit judges that an earthquake has occurred, and the power supply to the receptacle is cut off from this point. Yes.

  However, in this first related technique, a special wiring device is inserted on a wall-embedded outlet, and an electric product plug is inserted into this. Therefore, the wiring apparatus protrudes from the wall-embedded outlet arranged on the wall surface by the thickness, and a large space is required when an electric product plug is further inserted into the wiring apparatus. In addition, since the wiring device is inserted on the outlet, the wiring device itself lacks stability. For this reason, it is difficult for the device part that senses the internal vibration of the wiring device to distinguish between the daily vibration and the vibration of the earthquake, and there is a problem that the earthquake determination unit is expensive and the price of the wiring device itself is expensive. . In addition, since the wiring device can be easily removed from the outlet, the wiring device itself may be lost due to mischief or the like of the child, and may not be useful when an abnormal abnormality occurs.

  Therefore, the present inventor has proposed a wiring system that can provide a plug insertion port on the wall surface and can cut off the power supply at the time of abnormality relatively inexpensively as a second related technique (see Patent Document 2). The seismic sensor used in the wiring system of the second related technology has a projection that protrudes upward from the upper surface of the cylindrical metal body on the extension of the central axis, and a lower surface of a weight disposed on the cylindrical metal body. It stands still in a state where it overlaps with a protrusion protruding downward from the top and bottom, and waits for the occurrence of an earthquake. In this standby state, when an earthquake occurs and the position of the two protrusions shifts due to vibration and the weight moves downward, the contact of the mechanical switch that is linked to the vertical movement of the weight opens, and the power to the outlet Supply is cut off.

JP 2002-367737 A (paragraphs 0018 and 0019, FIG. 1) Japanese Patent Laying-Open No. 2004-304964 (paragraphs 0029 to 0031, FIG. 1)

  According to the second related technique, various problems caused by the first related technique can be solved by incorporating the seismic sensor itself into the outlet. However, in the second related technique, once the seismic sensor detects an earthquake, it is necessary to accurately superimpose the projection of the weight again on the projection of the cylindrical metal body using a mechanical reset mechanism. If the reset mechanism operates incompletely, the contact of the switch cannot be mechanically closed, and there is a problem that the wiring does not return normally. Therefore, realization of a highly reliable reset mechanism is indispensable, but it was difficult in view of miniaturization of the mechanism.

  Accordingly, an object of the present invention is to provide a seismic sensor that does not require a mechanical reset mechanism that accompanies vibration detection, and a recovery-abnormality outlet and wiring system that prevents power supply from being resumed when the vibration stops. There is to do.

  <First Embodiment of the Invention>

  Next, a first embodiment of the present invention will be described.

  FIG. 7 shows a cross-sectional structure of the seismic sensor according to the first embodiment of the present invention. The seismic sensor 100 has a rectangular parallelepiped shape, and has a structure in which an upper end and a lower end of an apparatus main body 101 formed of resin are sealed by a resin bottom lid 102 and an upper lid 103.

  One end of the first electrode plate 105 is exposed from the boundary position between the upper part of the one side surface 104 of the apparatus main body 101 and the upper lid 103. Further, one end of the second electrode plate 106 is exposed from the boundary position between the same side surface 104 and the bottom cover 102 in the lower part of the apparatus main body 101. The first electrode plate 105 has a short straight portion from the middle of one L-shaped metal plate in the direction opposite to the direction of the short straight portion 105A of the metal plate, that is, from the middle of the long straight portion 105B. A plate-like member having a shape in which a short straight portion 105C having the same length as 105A protrudes in the opposite direction to the straight portion 105A is used. This one plate-like member bends the two short straight portions 105A and 105C at right angles to the long straight portion 105B so as to bend in the same direction.

  A rectangular parallelepiped upper concave portion 111 is formed in the upper part of the apparatus main body 101. A wall member 112 having a height shorter than the depth of the upper space 111 from the bottom by the thickness of the straight portion 105B of the first electrode plate 105 protrudes in the center of the upper recess 111 in a cylindrical shape. The two straight portions 105 </ b> A and 105 </ b> C of the first electrode plate 105 are fixed by bonding the apparatus main body 101 and the upper lid 103 while sandwiching the outer wall surface of the wall member 112.

  A rectangular parallelepiped lower recess 113 is formed from the center to the lower part of the inside of the apparatus main body 101. The bottom of the cylindrical space 111A partitioned by the wall member 112 in the upper recess 111 has a partially spherical shape that is recessed downward by a surface 114 that forms a part of the spherical surface. Due to this partial spherical shape, an opening 115 having a predetermined diameter D communicating with the lower recess 113 is formed at the center of the bottom of the upper recess 111.

  The second electrode plate 106 disposed at the bottom of the lower recess 113 includes a first linear portion 106A having one end protruding as a terminal outside the apparatus main body 101, and a second line bent at a right angle from the other end side. It is comprised from the linear part 106B. The second straight portion 106B is processed into a shape whose cross section is folded back in a U-shape. As a result, the portion 106BA farthest in the height direction from the first straight portion 106A (hereinafter referred to as the support portion) 106BA is in a state before the turn in the second straight portion 106B, and the bottom portion of the lower recess 113 after processing. They are parallel at a predetermined interval.

  In the support portion 106BA, the vicinity of one end of the plate-shaped diaphragm 116 shown in the figure is fixed by a rivet 117. A part of the diaphragm 116 is formed by pressing so as to form a dish-like portion 116 </ b> A whose periphery protrudes into the shape of a round dish. Therefore, at the position of the cross section shown in FIG. 7, the head of the rivet 117 is hidden behind the dish-like portion 116A and is not shown.

  A metal pendulum 118 (118A, 118B, 118C) is inserted into the lower recess 113 by a predetermined distance from the opening 115 located at the bottom of the cylindrical space 111A. The pendulum 118 includes a head portion 118A having a diameter larger than that of the opening 115, a body portion 118B having a diameter smaller than that of the opening portion 115, and a contact portion 118C processed into a tapered shape at the tip of the body portion 118B. .

  FIG. 8 shows the pendulum as a single component. This will be described with reference to FIG.

  The head 118A of the pendulum 118 has a projection 118AA formed at the center of the top thereof. The protrusion 118AA is used to fix the lower end side of the first compression spring 121 to the head 118A of the pendulum 118 in the cylindrical space 111A.

  The lower half of the head portion 118 </ b> A forms a partial spherical surface having the same curvature as the surface 114. Therefore, the pendulum 118 is swingable around the center of the sphere constituting the partial spherical surface in a state where the lower half surface of the head portion 118A is pressed against the bottom of the cylindrical space 111A by the first compression spring 121. Yes.

  The body portion 118B forms a small diameter portion 118BA in which the vicinity of the end connected to the contact portion 118C is cut into a ring shape. A fastener 123 is attached to the small diameter portion 118BA, and a washer 124 having an inner diameter larger than the outer diameter of the body portion 118B is attached thereon. A second compression spring 125 is mounted on the washer 124 so that the outer periphery of the body portion 118B can move up and down. The washer 124 serves to limit the downward movement of the second compression spring 125.

  A cylindrical first weight 126 having a U-shaped cross section is attached to the body portion 118B so as to be movable up and down. A second compression spring 125 is housed in a compressed state between the washer 124 and the ceiling portion of the recess 127 opened downwardly of the first weight 126. When the pendulum 118 swings left and right or moves up and down by an external force such as an earthquake, the second compression spring 125 has a role of converging these vibrations at an early stage to make the body portion 118B stationary in the vertical direction. Yes.

  The contact portion 118C has a tip end portion 118CA that forms a partial spherical surface and is rounded. The distal end portion 118CA maintains a state in which the body portion 118B is in sliding contact with the inner surface of the dish-shaped portion 116A while the body portion 118B is stationary in the vertical direction. In this state, the first electrode plate 105 and the second electrode plate 106 are electrically connected via the first compression spring 121, the pendulum 118, and the diaphragm 116.

  On the other hand, when the pendulum 118 swings left or right and the tip end portion 118CA is separated from the inner surface or the outer periphery of the dish-shaped portion 116A, the electrical connection between the first electrode plate 105 and the second electrode plate 106 is performed. Connection is broken. FIG. 7 specifically shows the time when the pendulum 118 swings using a one-dot chain line. Assuming that the pendulum 118 swings to the right as shown in the drawing, the tip 118CA is away from the dish-shaped portion 116A during that time.

  FIG. 9 illustrates a main part of the seismic sensor according to the first embodiment. One end of the diaphragm 116 constituting the seismic sensor 100 is positionally fixed by the support portion 106BA of the second electrode plate 106 by the rivet 117 as already described. The other end of the diaphragm 116 is a free end, and a second weight 131 is fixed in the vicinity of the free end.

  Further, with the pendulum 118 stationary and its tip 118CA (FIG. 8) is in contact with the inner center of the dish-shaped portion 116A, the diaphragm 116 is kept almost horizontal. At this time, the end portion 116B on the free end side of the diaphragm 116 is positioned slightly below the protruding portion 101A partially protruding from the inner wall of the lower recess 113. The protrusion 101 </ b> A has a role of regulating the upper limit position of the vibration of the diaphragm 116 when vertical vibration is applied to the seismic sensor 100.

  The operation when the pendulum 118 is given a force to vibrate in the vertical direction will be described using a one-dot chain line in FIG. It is assumed that a force that causes the pendulum 118 to oscillate in the vertical direction due to an earthquake or the like is increased to a certain extent. Then, at a certain timing, the lower end portion of the first weight 126 comes into contact with the upper end portion of the second weight 131 and pushes it downward. Then, at this timing, the tip end portion 118CA of the pendulum 118 is separated from the dish-shaped portion 116A. Also at this time, the electrical connection between the first electrode plate 105 and the second electrode plate 106 shown in FIG. 7 is temporarily turned off.

FIG. 10 shows a main part of the circuit configuration of an abnormal-time wall-embedded outlet using a seismic sensor. The wall socket type outlet 200 for responding to an abnormality includes an exciting coil (L _{1) of} the first relay circuit 201 between the first electrode plate 105 and the second electrode plate 106 of the seismic sensor 100 shown in FIG. ) 202 and a first DC power source 203 are provided in series. When the seismic sensor 100 senses a roll or pitch corresponding to, for example, a seismic intensity of a predetermined level or more, the first circuit portion 204 is at least temporarily between the first electrode plate 105 and the second electrode plate 106. Turn off.

In addition to the first circuit portion 204, the abnormal-time wall-embedded outlet 200 includes a second circuit portion 205 and a third circuit portion 206. The second circuit portion 205 includes a second DC power supply 208, and a normally open (NO) contact 209 of the first relay circuit 201 and a second relay circuit are connected to the second DC power supply 208. A series circuit of 207 exciting coils (L ₂ ) 210 is connected. Further, the normally open contact 209 of the first relay circuit 201 is connected in parallel with a normally open contact 211 of the second relay circuit 207 and a series circuit including a reset switch 212 that is normally on. .

  Therefore, when the exciting coil 202 of the first circuit portion 204 is excited, the normally open contact 209 of the first relay circuit 201 is closed and the exciting coil 210 of the second relay circuit 207 is excited. As a result, the normally open contact 211 is closed and the second relay circuit 207 is held by itself. That is, when the space between the first electrode plate 105 and the second electrode plate 106 of the seismic sensor 100 is temporarily turned off, the second relay circuit 207 of the second relay circuit 207 is subsequently turned on even when the space between them is turned on again. The normally open contact 211 is continuously turned on. This on state continues unless the user manually turns off the reset switch 212.

  The third circuit portion 206 includes a pair of blade receiving brackets 214 and 215 attached to the abnormal-time wall-embedded outlet 200 as circuit components. One blade receiving bracket 214 is connected to one end of a normally closed contact (NC) 216 of the second relay circuit 207 and the other end is connected to one end of a commercial power source 217 wired in the house. Yes. The other end of the commercial power source 217 is connected to one end of a thermo switch 218 such as a bimetal, and the other end is connected to the other blade receiving bracket 215. The thermo switch 218 is a switch that opens a contact when a temperature rises above a predetermined temperature by detecting an indoor fire or abnormal heat generation in the outlet. The normally closed contact 216 of the second relay circuit 207 and each contact of the thermo switch 218 have a contact structure that enables on / off of the current of the rated power.

  In an initial state in which vibration exceeding the specified level due to an earthquake or the like is not applied to the house in which the wall-type outlet 200 for emergency response is embedded, the normally closed contact 216 of the second relay circuit 207 is on. Therefore, the commercial power source 217 is supplied to the pair of blade receiving brackets 214 and 215 in a state where the thermo switch 218 does not sense an abnormal temperature, and the use is possible. Assume that an earthquake with a seismic intensity equal to or greater than that occurs in this state. Then, the seismic sensor 100 detects this and the normally closed contact 216 of the second relay circuit 207 is turned off. Even when the shaking of the earthquake is stopped and the space between the first electrode plate 105 and the second electrode plate 106 shown in FIG. 7 is turned on again, the normally closed contact 216 of the relay circuit 208 is maintained in the off state. Even if a power plug (not shown) is attached to the blade receiving brackets 214 and 215, power is not supplied to the power plug. Thereby, even if an electric power company recovers the supply of the commercial power source 217, for example, it is possible to prevent a situation in which an electric stove that has fallen due to an earthquake generates heat and a fire occurs.

  The user presses the reset switch 212 after checking the safety of the home appliance using the wall-type outlet 200 corresponding to the abnormality. Then, the exciting coil 210 of the second relay circuit 207 is demagnetized, the normally open contact 211 is turned off again, and the self-holding circuit cancels the self-holding. As a result, the normally closed contact 216 of the second relay circuit 207 is turned on again, and supply of the commercial power source 217 to the pair of blade receiving brackets 214 and 215 is started unless the thermo switch 218 senses an abnormal temperature. Will be.

FIG. 11 shows an example of a wiring system using the abnormal-time wall-embedded outlet according to the first embodiment. A house 301 to which the wiring system 300 is applied is provided with a breaker (distribution panel) 302 as an entrance for supplying electric power from the outside, and electric wires 304 to 306 for each system are connected to the respective internal branch breakers. Has been. In this example, the electric wire 304 of the 1st system is connected to the lighting fixtures 307-309. The second electric wire 305 is connected to the air conditioner 311. The electric wires 306 of the third system are connected to the abnormal-time wall-embedded outlet 200 and the normal-time wall-embedded outlets 321 ₁ , 321 _{2 according} to the first embodiment. The normal-time wall-embedded outlets 321 ₁ and 321 ₂ are conventional wall-embedded outlets that have been used in the past, and do not have a power supply cutoff function against an earthquake or fire.

  <Second Embodiment of the Invention>

  Next, a second embodiment of the present invention will be described.

  FIG. 12 shows a cross-sectional structure of a seismic sensor according to the second embodiment of the present invention. The seismic sensor 400 of the second embodiment also has a rectangular parallelepiped shape, and has a structure in which the upper end and lower end of the apparatus main body 401 formed of resin are sealed by a resin bottom lid 402 and an upper lid 403. It has become.

  One end of the first electrode plate 405 is exposed from the boundary position between the upper portion of one side surface 404 of the apparatus main body 401 and the upper lid 403. In addition, one end of the second electrode plate 406 is exposed from the boundary position between the same side surface 404 and the bottom cover 402 at the lower part of the apparatus main body 401. The first electrode plate 405 has a short straight portion from the middle of one L-shaped metal plate in the direction opposite to the direction of the short straight portion 405A of the metal plate, that is, from the middle of the long straight portion 405B. A plate-like member having a shape in which a short straight portion 405C having the same length as 405A protrudes in a direction opposite to the straight portion 405A is used. This one plate-like member bends the two short straight portions 405A and 405C at right angles to the long straight portion 405B so as to bend in the same direction.

  First to third upper concave portions 411 to 413 are formed inside the upper lid 403 so that the respective bottom portions are in contact with the upper portion of the apparatus main body 401. Of these, a straight portion 405C is arranged on the inner wall located at the right end portion in the drawing of the first upper recess 411, and a straight portion is placed on the inner wall located at the left end portion in the drawing of the third upper recess 413. 405A is arranged. These two straight portions 405C and 405A play a role of fixing the electrode plate 405 at a predetermined position in the seismic sensor 400 together with the upper lid 403 and the apparatus main body 401.

  The second upper concave portion 412 is a substantially cylindrical space having a circular cross section when cut perpendicular to the paper surface. The bottom of the second upper recess 412 communicates with a lower recess 414 opened in the apparatus main body 401 by a cylindrical opening 415 having a circular cross section. The flat plate portion having a predetermined width that forms the straight portion 405B of the electrode plate forms a raised portion 405D that bulges upward about the point through which the central axis of the cylindrical opening 415 passes. A circular hole 416 which is shorter than the diameter of the cylindrical opening 415 and is concentric with the portion corresponding to the top of the raised portion 405D is formed.

  The second electrode plate 406 disposed at the bottom of the lower concave portion 414 includes a first linear portion 406A having one end protruding as a terminal to the outside of the apparatus main body 401 and a second linear portion bent at a right angle from the other end side. It is comprised from the linear part 406B. The second straight line portion 406B is processed into a shape whose cross section is folded back in a U shape. As a result, a portion (hereinafter referred to as a support portion) 406BA that is farthest in the height direction from the first straight portion 406A in the state before the folding in the second straight portion 406B is the bottom portion of the lower recess 414 after processing. They are parallel at a predetermined interval.

  A diaphragm 417 made of a conductor is fixed on the support portion 406BA by a rivet 117. The diaphragm 417 forms a protrusion 417A whose center position is raised. The rivet 117 positions the diaphragm 417 in the horizontal direction so that its legs are positioned at the apex of the protrusion 417A when a perpendicular line is drawn from the center position of the cylindrical opening 415.

  A metal pendulum 419 (419A, 419B, 419C) is inserted from the circular hole 416 of the cylindrical second upper recess 412 toward the lower recess 414 by a predetermined distance. The pendulum 419 includes a head portion 419A having a diameter larger than that of the circular hole 416, a body portion 419B having a diameter smaller than that of the circular hole 416, and a contact portion 419C processed in a tapered shape at the tip of the body portion 419B. .

  FIG. 13 shows the pendulum as a single component. This will be described with reference to FIG.

  A head 419A of the pendulum 419 has a disk shape. The head 419 </ b> A has a downward force due to the weight of the pendulum 419. Therefore, the first compression spring 121 shown in FIG. 7 of the first embodiment is not used. Of course, a protrusion as shown in FIG. 7 may be arranged on the head 419A, and one end of the compression spring may be fixed thereto.

  The lower surface of the head 419A is supported by the upper end of the raised portion 405D shown in FIG. In this state, the body portion 419B can swing within a free space defined by the circular hole 416 and the cylindrical opening 415.

  The body portion 419B forms a small-diameter portion 419BA in which the vicinity of the end connected to the contact portion 419C is cut into a ring shape. A fastener 423 is attached to the small diameter part 419BA, and a washer 424 having an inner diameter larger than the outer diameter of the body part 419B is attached thereon. A compression spring 425 is mounted on the washer 424 so that the outer periphery of the body portion 419B can move up and down. The washer 424 serves to limit the downward movement of the compression spring 425.

  A cylindrical first weight 426 having a U-shaped cross section is attached to the body portion 419B so as to be movable up and down. A compression spring 425 is accommodated in a compressed state between the washer 424 and the ceiling portion of the recess 427 opened downward of the first weight 426. When the pendulum 419 swings to the left or right by an external force such as an earthquake or moves in the vertical direction, the compression spring 425 has a role of converging these vibrations at an early stage to make the body 419B stationary in the vertical direction.

  The contact portion 419C is a portion corresponding to the hypotenuse of an isosceles triangle, excluding its tip, and when the pendulum 419 attached with the first weight 426 is stationary under its own weight, the cross section is also on the hypotenuse of the isosceles triangle. It contacts the outer peripheral portion of the corresponding protrusion 417A. In this contact state, the two isosceles triangles are opposite to each other, and the oblique sides of the contact part are parallel to each other.

  Further, the surface of the contact portion 419C and the protrusion portion 417A is processed by gold plating. For this reason, the pendulum 419 and the second electrode plate 406 are electrically connected well in a state where the pendulum 419 is stationary due to its own weight. The upper surface of the raised portion 405D of the first electrode plate 405 and the head portion 419A of the pendulum 419 are also processed by gold plating. For this reason, the first electrode plate 405 and the pendulum 419 are always electrically connected well. That is, the first electrode plate 405 and the second electrode plate 406 are electrically connected in a state where no vibration such as an earthquake is applied to the pendulum 419.

  On the other hand, when the pendulum 419 swings and the contact portion 419C moves away from the protrusion 417A, the electrical connection between the first electrode plate 405 and the second electrode plate 406 is cut off. FIG. 12 specifically shows the time when the pendulum 419 swings using a one-dot chain line. Assuming that the pendulum 419 swings in the right direction as shown in the figure, the contact portion 419C is in a state of being separated from the projection portion 417A.

  FIG. 14 illustrates a main part of the seismic sensor according to the second embodiment. One end of the vibration plate 417 constituting the seismic sensor 400 is positionally fixed by the support portion 406BA of the second electrode plate 406 by the rivet 418 as already described. The other end of the diaphragm 417 is a free end, and a second weight 431 is fixed in the vicinity of the free end.

  In addition, with the pendulum 419 standing still and its contact portion 419C in contact with the protrusion 417A, the diaphragm 417 is kept almost horizontal. At this time, the end 417B on the free end side of the vibration plate 417 is positioned slightly below the protrusion 401A partially protruding from the inner wall of the lower recess 414. The protrusion 401A has a role of regulating the upper limit position of vibration of the diaphragm 417 when vertical vibration is applied to the seismic sensor 400.

  The operation when the pendulum 419 is given a force to vibrate in the vertical direction will be described using a one-dot chain line in FIG. It is assumed that a force that causes the pendulum 419 to vibrate in the vertical direction due to an earthquake or the like is increased to a certain extent. Then, at a certain timing, the lower end portion of the first weight 426 comes into contact with the upper end portion of the second weight 431 and pushes it downward. Then, at this timing, the contact portion 419C of the pendulum 419 is separated from the protrusion 417A. Also at this time, the electrical connection between the first electrode plate 405 and the second electrode plate 406 shown in FIG. 12 is temporarily turned off.

  The circuit configuration of the abnormal-time wall-embedded outlet shown in FIG. 10 can also be applied to the seismic sensor 400 of the second embodiment. However, “seismic sensor 100” shown in FIG. 10 is replaced with “seismic sensor 400”, “first electrode plate 105” is replaced with “first electrode plate 405”, and “second electrode plate 106” is replaced. "Is replaced with" second electrode plate 406 ". FIG. 11 can also be applied to the seismic sensor 400 of the second embodiment.

  FIG. 15 shows the connection relationship of the outlets in the first example to which the wiring system of the first embodiment is applied.

The third connection terminal 363 electrically connected to the first connection terminal 361 is used for wiring of a subsequent outlet. The fourth connection terminal 364 electrically connected to the second connection terminal 362 is also used for wiring of the subsequent outlet.

As described above, the first and second normal-time-capable wall-embedded outlets 321 ₁ and 321 ₂ do not include the seismic sensor 100, its associated circuit, and the thermo switch 218. However, connecting the first and second normal-time embedded wall outlets 321 ₁ , 321 ₂ in series to the abnormal-time wall-embedded outlet 200 allows the abnormal-wall-type outlet 200 to be abnormal. When the power supply to the corresponding plug is detected and detected, the first and second normal-time corresponding wall-embedded outlets 321 ₁ and 321 ₂ also turn off the power supply to the corresponding plug.

  FIG. 16 shows an external appearance when the wall-embedded outlet is embedded in the wall. The lower half of the first embodiment is provided with a plug insertion portion 371 in the abnormal-time wall-embedded outlet 200. Here, power supply insertion ports 372 and 373 and a ground insertion port 374 corresponding to the pair of blade brackets 214 and 215 shown in FIG. 10 are provided.

  In addition, two LED (Light Emitting Diode) lamps, a normal lighting lamp 375 and an abnormal lighting lamp 376, and a reset switch 212 are arranged above the plug insertion part 371 where another set of plug insertion parts is originally arranged. Has been. The normal lighting lamp 375 is, for example, a green lamp, and indicates that the specified abnormal earthquake has not occurred and the temperature inside the abnormal-time wall-embedded outlet 200 is normal. In a state where the normal lighting lamp 375 is lit, power is supplied to the plug insertion portion 371.

The abnormal lighting lamp 376 is a red lamp, for example, and indicates that a specified abnormal earthquake has occurred or that the temperature inside the wall-type outlet 200 corresponding to an abnormal time has become abnormal. In the state where the abnormal lighting lamp 376 is lit, power is not supplied to the plug insertion portion 371. The user presses the reset switch 212 after searching for the cause of the abnormality and confirming the state of the electrical product to be used. At this time, if the cause of the abnormality is gone, the abnormal lighting lamp 376 is turned off and the normal lighting lamp 375 is turned on instead, and the supply of power to the plug insertion portion 371 is started. If power is supplied to the abnormal-time wall-embedded outlet 200, power is also supplied to the first and second normal-time wall-embedded outlets 321 ₁ and 321 ₂ .

Of course, there is a case where it is desired to always supply power to the first and second normal-time corresponding wall-embedded outlets 321 ₁ and 321 ₂ regardless of whether the power supply of the abnormal-time wall-embedded outlet 200 is turned on or off. Further, it is necessary to start supplying power to the first and second normal-time wall-embedded outlets 321 ₁ and 321 ₂ without waiting for a reset operation of the reset switch 212 when the commercial power supply is restored. In some cases. For example, to listen to earthquake information, a radio is connected to the first normal-time-internal wall outlet 321 ₁ , or an Internet connection router is connected to the second normal-time-internal wall outlet 321 ₂ . Is the case. In such a case, one end of the electric wire 341 ₁ may be connected to the upstream side of the power supply with respect to the normally closed contact 216 of the second relay circuit 207. As a result, commercial power can be supplied to the first and second normal-time wall-embedded outlets 321 ₁ and 321 ₂ regardless of whether or not the second relay circuit 207 operates.

  FIG. 17 shows the connection relationship of the outlets in the wiring system according to the second embodiment of the present invention. In the wiring system 300B of the second embodiment, the same parts as those in FIG. 15 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

In the second embodiment, in addition to the third electric wire 306, a fourth electric wire 381 is prepared. Third fault response-wall outlet 200 ₇ having a seismic sensor 100 ₇ for detecting an abnormality when there is an earthquake or more "seismic intensity 7" is towards the system of wires 306, one stage of the parallel connection Connected to the eyes. Further, fault response-wall outlet 200 ₅ with a seismic sensor 100 ₅ for detecting an abnormality when there is an earthquake or more "seismic intensity 5" toward the fourth line of the electric wire 381, connected in parallel Connected to the first stage. The subsequent stage of one of the fault response-wall outlet 200 _7, when the first and second ordinary correspondence-wall outlet 321 _1, 321 _2, using a wire 341 _1, 341 _2, 342 _1, 342 ₂ The connection is the same as in FIG. The subsequent stage of the other fault response-wall outlet 200 _5, third and fourth normal response-wall outlet 321 _3, 321 _4, using a wire 343 _1, 343 _2, 344 _1, 344 ₂ The connection is the same as in FIG.

Thus, when the earthquake is less than "seismic intensity 7" in the wiring system in 300B "intensity 5" or more of the second embodiment is generated, the fault response-wall outlet 200 ₅ the third and fourth normal response The wall-embedded outlets 321 ₃ and 321 ₄ stop their power supply all at once. Also, if the seismic intensity 7 or earthquake occurs not only two fault response-wall outlet 200 _5, 10 _7, four normal response-wall outlet 321 _{1-321 4} feeding them It will stop all at once. Thus, it is possible to economically create a wiring system according to the degree of earthquake. In the second modification, the description of the operation when the temperature becomes abnormal is omitted.

  FIG. 18 shows a wiring system according to a third embodiment of the present invention. In the wiring system 300C of the third embodiment, the same parts as those in FIG. 15 or FIG. 17 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

In the third embodiment, the abnormality at the next stage of the corresponding-wall outlet 200 ₇ having a seismic sensor 100 ₇ for detecting an abnormality when there is an earthquake or more "seismic intensity 7" first normal when corresponding wall connecting the implantable outlet 321 _1, fault response-wall outlet 200 ₅ with a seismic sensor 100 ₅ for detecting an abnormality when there is "intensity 5" or more seismic to the next stage Is connected. Further, a second normal-time-capable wall-embedded outlet 322 ₂ is connected to the next stage, and a seismic sensor 100 ₃ for detecting an abnormality when an earthquake having a seismic intensity of 3 or higher is detected in the next stage. and the fault response-wall outlet 200 ₃ are connected. As it is further connected next third the normal response-wall outlet 321 _3.

As a result, when an earthquake of “seismic intensity 3” or more and less than “seismic intensity 5” occurs, power supply to the abnormal-time-corresponding wall-embedded outlet 2003 ₃ and the third normal-time-corresponding wall-embedded outlet 321 ₃ is stopped. Moreover, the "intensity 5" or more seismic below 'seismic intensity 7 "occurs, fault response-wall outlet 200 ₃ and fault response-wall outlet 200 ₅ and the second and third normal corresponding wall implantable The power supply to the outlets 321 ₂ and 321 ₃ is stopped. Further, when "seismic intensity 7" or more earthquake would feed all implantable outlet 200 _3, 200 _5, 200 _7, 321 ₁ to 321 ₃ shown in FIG. 18 is stopped.

  In the connection structure shown in FIG. 18, the wall socket type outlet 200 for detecting an earthquake having a large seismic intensity is arranged closer to the breaker 302 or the switchboard shown in FIG. 11. Therefore, even if the abnormal-time-corresponding wall-embedded outlet 200 on the side where the seismic intensity is small fails for some reason, the seismic intensity increases so that a larger seismic intensity is detected. If is operated, all power supply is cut off after that. Therefore, it is possible to take a more reliable measure against an abnormality.

  In the first and second embodiments and each example described above, the present invention is applied to the abnormalities of the earthquake and the temperature rise of the wall-embedded outlet, but the present invention is also applied when other abnormalities are detected. The same can be applied. In addition, there are various methods for detecting earthquakes and abnormal temperatures, and it is not limited to the specific detection principle or detection configuration shown in the first and second embodiments and each example. Of course. Furthermore, the present invention is naturally applicable to abnormal vibrations other than earthquakes.

  Moreover, the seismic sensor 100 shown in FIG. 7 and the seismic sensor 400 shown in FIG. 12 are sensors that can be used independently, and are necessarily used by being incorporated in the wall outlet type wall outlet 200 corresponding to an abnormality. There is no need. For example, it is possible to attach the seismic sensors 100 and 400 to the side of a gas stove used on a table and stop the gas emission using a circuit that holds the output.

  According to the seismic sensor 100 of the first embodiment described above, by adjusting the spring pressure of the first compression spring 121 and the second compression spring 125, the sensitivity to the earthquake and the dish-shaped portion 116A can be adjusted. The tip 118CA of the pendulum can be adjusted. Moreover, in the second related technology, the weight placed on the pendulum is dropped by the vibration of the pendulum, so it is necessary to accurately reset the dropped weight to the upper end of the pendulum at the time of resetting. The form of the seismic sensor 100 does not require such a complicated mechanism, and can improve the reliability of the apparatus.

  In addition, when incorporating the seismic sensors 100 and 400 into a device such as the wall socket type outlet 200 for handling an abnormal time, the sensor itself does not necessarily have a sealed structure. For example, some devices such as the device main body 101 shown in FIG. 7 may be omitted, or a device may be simplified by embedding a terminal in the device to reduce the size and weight of the seismic sensor. Of course, the cost can be reduced.

  In addition, according to the embodiment described above, even if the subsequent outlet of the wall-type outlet corresponding to the abnormal time is a wall-type outlet corresponding to the normal time that is not the wall-type outlet corresponding to the abnormal time, the power is supplied to the electric product at the time of abnormality. The supply of power can be cut off in the same manner, and an economical wiring system can be constructed. This can greatly reduce the occurrence of troubles caused by energization.

  In addition, by disconnecting the contact point on the switchboard or the power supply side by an earthquake with a greater seismic intensity, it is possible to cope with smaller earthquakes due to some troubles. Since the wall-embedded outlet can be disconnected due to displacement caused by a greater earthquake and the power supply downstream can be cut off, a highly reliable wiring system can be configured at low cost.

  Furthermore, an LED lamp that lights up in the normal state, an LED lamp that lights up in the abnormal state, and a reset switch are arranged on the surface of the wall-embedded outlet corresponding to the abnormal time. Accordingly, the user can easily isolate the failure when an electric appliance such as a home appliance connected to the outlet does not operate. In addition, when an LED lamp that is lit when an abnormality occurs, the safety of an electric appliance such as a home appliance can be confirmed before pressing the reset button.

  In the embodiment, the wall-removable outlet for abnormal situations is provided with one set of plug insertion portions 371. However, for example, the earth insertion port 374 may be omitted and two sets of plug insertion portions may be provided. Is possible. In the embodiment, the lower half of the head portion 118A of the pendulum 118 is a partial spherical surface having the same curvature as the surface 114, but may be a partial spherical surface having a shorter diameter. Instead of the reset switch, a reset hole for moving the first weights 126 and 426 with an object such as a wire mechanically inserted from the outside may be provided.

  Moreover, although the embodiment has been described on the assumption that the wall-type outlet for responding to abnormalities cuts the power supply by one relatively large vibration, the present invention is not limited to this. In a normal earthquake, large shakes occur multiple times simultaneously. Therefore, an electrical counting circuit may be arranged in the seismic sensor, and it may be detected that abnormal vibration has occurred when the OFF state appears continuously for a predetermined number of times of two or more. . Thereby, it is possible to prevent a detection error such that the power supply is stopped when the user of the abnormal-time wall-embedded outlet accidentally hits a foot or an object against the abnormal-wall-compatible wall outlet.

  Furthermore, although the first embodiment and the second embodiment and each example have been described with respect to an abnormal-time wall-embedded outlet, the abnormal-time outlet according to the present invention is not limited to an outlet that is embedded in a wall. The name of the outlet is not limited as long as the outlet is fixed in position and the built-in seismic sensor can accurately detect an earthquake. For example, there is a case where an outlet called an exposed outlet or a temporary outlet mainly attached to a pillar or wall of a house or factory after construction is fixed and power is supplied to the plug. Naturally, the present invention can also be applied to an outlet exposed from the surface of such a pillar or wall.

  In addition, when wiring is performed using a plurality of seismic sensors having different seismic intensities, it is natural that the power supply of each outlet can be controlled by various combinations other than those described in the embodiment.

  Further, in the first embodiment, as shown in FIG. 7 or FIG. 8, the front end portion 118CA of the contact portion 118C is in contact with the inner surface of the dish-shaped portion 116A. The contacted portion does not necessarily have to be recessed in a dish shape. Further, although the seismic sensor 100 has a sealed structure in the embodiment, it is not necessarily required to be sealed.

  FIG. 19 corresponds to FIG. 7 and shows another shape of the diaphragm. In the seismic sensor 100A of the modification of the first embodiment, a part of the plate-like diaphragm 501 is pressed so that the cone is horizontally cut at a predetermined height and the upper part is removed. 501A is formed. Also in this modified example, the tip 118CA (see FIG. 5) of the contact portion 118C is in contact with a flat portion that forms the upper portion of the convex portion 501A while the metal pendulum 118 is stationary. Then, as shown by the one-dot chain line in FIG. 19, the pendulum 118 rolls over a predetermined angle or the contact piece 131 (see FIG. 9) of the weight 126 is pushed down by the vertical vibration of the seismic sensor 100A. As a result, the front end portion 118CA and the convex portion 501A are temporarily in non-contact.

  The first to third examples described above can be applied not only to the first embodiment but also to the second embodiment.
