According to this configuration, even if an earthquake with a set seismic intensity does not occur, when the house tilts, it is detected, the electric path is shut off, and the power supply to the outlet is shut off. Therefore, when it becomes a state which is easy to generate a short circuit and a fire, outlet outlet output can be stopped certainly and generation of a fire, an electric shock accident, etc. can be prevented. Moreover, by installing on a wall surface, there is no possibility of erroneously detecting the inclination of a house.

The invention according to claim 2 is characterized in that in the configuration according to claim 1, the earthquake sensing unit has an acceleration sensor to sense an earthquake and also sense an inclination, and also serves as a collapse sensing unit.

According to this configuration, by connecting the signal input / output terminals of the embedded socket device to each other, if the earthquake sensing unit of any of the connected embedded socket devices outputs an earthquake occurrence signal, the connection is started from itself. All embedded receptacle devices being shut off operate. Therefore, even if there is an embedded type outlet device in which the earthquake sensing unit has failed, by interconnecting a plurality of embedded type outlet devices, it is possible to cut off the outlet output reliably in response to an earthquake.

The invention of claim 4 is characterized in that, in the configuration according to any one of claims 1 to 3, it has a tracking detection unit for detecting a tracking discharge, and the shutoff control unit shuts off the electric path when the tracking discharge occurs. Do.
According to this configuration, since the electric path is shut off when the tracking discharge is detected, the occurrence of a fire can be reliably prevented.

The invention according to claim 5 is characterized in that, in the configuration according to claim 4, the display unit displays whether the interruption cause is due to earthquake detection or tracking generation.
According to this configuration, it is easy to grasp and cope with whether the interruption cause is due to the earthquake or the tracking later by the display of the display unit.

The invention according to claim 6 is characterized in that, in the configuration according to any one of claims 1 to 5, it has a sound notification unit for notifying a notification sound when the blocking mechanism unit operates.
According to this configuration, since the notification sound is notified when the shutoff mechanism unit operates, the resident can recognize that the shutoff operation has been performed, and it is easy to handle.

  According to the present invention, even if an earthquake with a set seismic intensity does not occur, when the house is tilted, the shutoff operation is performed to shut off the power supply to the outlet. Therefore, when it becomes a state which is easy to generate a short circuit and a fire, outlet outlet output can be stopped certainly and generation of a fire, an electric shock accident, etc. can be prevented. Moreover, by installing on a wall surface, there is no possibility of erroneously detecting the inclination of a house.

Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. FIG. 1 is a circuit block diagram showing an example of the embedded socket device according to the present invention. In the embedded socket device 1, an electric circuit interrupting mechanism 11 is provided in the middle of an electric circuit L of 100 V and the electric cable L is connected. It has a function to shut off the output from the outlet 12 which is being carried out.
Reference numeral 2 denotes a control unit, which operates the electric path interrupting mechanism 11 which performs an open operation by opening an on-off contact (not shown) which is interposed between the earthquake detecting portion 21 including the acceleration sensor 21a and the tracking detecting portion 22 and the electric path L.

In FIG. 2, the surface indicated by S is a front surface exposed from the wall surface, and the protrusion B on the right side is a portion accommodated in a not-shown outlet box disposed in the wall surface. The output terminal 26, the control unit 2 and the like are accommodated. In addition, the front surface S is covered and installed by the decorative board which is not illustrated.
In the embedded type outlet device 1, two outlets 12 are vertically disposed, and the display 24a, the operation lever 25 for opening and closing the electric path blocking mechanism 11, the test switch 28, and the reset switch 29 are disposed on the left side of the outlet 12. It is done.

  Reference numerals 31 and 32 shown in FIG. 3 denote connection portions of a 100 V power supply line consisting of two wires connected to the embedded socket device 1, and a neutral phase port (N phase port) 31 and a voltage phase port (L1 or L2 phase) And 32). The signal input / output terminal 26 is provided at the upper end of the projection B as shown in FIGS.

The earthquake sensing unit 21 detects the magnitude of the earthquake by the built-in acceleration sensor 21a, and outputs an earthquake occurrence signal to the outlet CPU 27 when it detects an earthquake of a predetermined seismic intensity such as seismic intensity 5 or higher. Ru.
In addition, the acceleration sensor 21a detects the inclination, recognizes the state where the implantable receptacle device 1 is installed on the wall surface as an upright state (state of 0 degree), for example, an inclination of an angle set at 45 degrees or more When the inclination of (4) occurs, it is determined that the vehicle has collapsed and a collapse signal is output to the outlet CPU 27. The seismic intensity threshold for outputting the earthquake occurrence signal and the threshold for the detected inclination are set at the time of shipment from the factory.

  The tracking detection unit 22 has a sensor hole 22a between two plug receptacles of the outlet 12, and a discharge generated between the blades of a plug (not shown) connected to the outlet 12 at the back of the sensor hole 22a. A sensor circuit for detecting (tracking discharge) is provided, and an internal circuit detects the occurrence of tracking via the sensor hole 22a. When the tracking detection unit 22 detects tracking, the outlet CPU 27 recognizes it and operates the electric path shut-off mechanism unit 11 through the power supply trip circuit 23.

  The power supply trip circuit 23 receives the trip signal (cutoff signal) output from the outlet CPU 27 and operates the circuit shutoff mechanism unit 11.

  The display part 24a which comprises the notification part 24 is comprised by LED, and displays a state by light emission or blink. In addition, the buzzer 24b constituting the notification unit 24 notifies of an alarm when the outlet CPU 27 outputs a trip signal in response to the operation of the circuit interruption mechanism unit 11.

The signal input / output IF 26a externally outputs an earthquake occurrence signal generated by the outlet CPU 27 of its own from the signal input / output terminal 26 to which the signal line is connected, and notifies the outlet CPU 27 when an earthquake occurrence signal is transmitted from the outside. Interface. By connecting the signal input / output terminal 26 to the signal input / output terminal 26 of another embedded socket device 1 via a signal line, interlocking of the embedded socket devices 1 is enabled.
The connection of the implantable receptacle devices 1 with each other through the signal line is carried out via an outlet control unit (not shown) in which the terminals are internally connected to each other, and a signal connected to the implantable receptacle device 1 The lines are all connected to the outlet control unit.

The implantable outlet device configured as described above operates as follows. When the earthquake occurrence signal is output from the earthquake sensing unit 21, the outlet CPU 27 outputs a trip signal to the power supply tripping circuit 23 to cause the circuit breaker 11 to shut off. As a result, the outlet 12 is disconnected from the power path L, and the power supply to the connected load (not shown) is stopped.
At the same time, the display unit 24a constituting the notification unit 24 is operated to blink, for example, and the display operation is performed to notify that the interruption operation is the interruption due to the occurrence of an earthquake. Further, the buzzer 24b is sounded to notify the resident of the operation of the circuit breaker 11 by a buzzer sound. The notification operation of the notification unit 24 is stopped by the operation of the reset switch 29.

  Also, even if the earthquake sensing unit 21 itself does not output an earthquake occurrence signal, if an earthquake occurrence signal is received from the outside via the signal input / output terminal 26, the outlet CPU 27 outputs a trip signal to the power supply trip circuit 23 Then, the circuit breaker mechanism 11 is operated to shut off. Also in this case, the notification unit 24 performs the above-described notification operation.

  Furthermore, the earthquake sensing unit 21 detects the tilt of the dwelling unit even if the sensed seismic intensity does not reach the set seismic intensity and does not output the earthquake occurrence signal, and outputs the collapse signal if the tilt is equal to or greater than the preset tilt. Do. In response to the collapse signal, the outlet CPU 27 outputs a trip signal to the power supply trip circuit 23 to cause the circuit breaker 11 to shut off. As a result, as in the case of receiving the earthquake occurrence signal, the outlet 12 is disconnected from the electric path L, and the power supply to the connected load (not shown) is stopped. Then, the buzzer 24b is sounded to notify that the circuit breaker mechanism 11 has operated.

  On the other hand, when tracking discharge occurs in the outlet 12, the tracking detection unit 22 detects it and outputs a tracking detection signal. The outlet CPU 27 that has received this tracking detection signal shuts off the electric path shut-off mechanism unit 11. Then, a display operation different from the interruption due to the occurrence of an earthquake, for example, an LED is made to light the indicator 24a, and the buzzer 24b is sounded to notify the resident that the electric circuit interruption mechanism unit 11 has operated by a buzzer sound.

As described above, even if an earthquake having a set seismic intensity does not occur, the shutoff operation is performed when the house is tilted, and the power supply to the outlet 12 is shut off. Therefore, the output of the outlet 12 can be reliably stopped when a condition such as a short circuit or a fire is likely to occur, and the occurrence of a fire or an electric shock accident can be prevented. Moreover, by installing on a wall surface, there is no possibility of erroneously detecting the inclination of a house. In addition, since the earthquake detection unit 21 also detects the inclination of the house, a separate collapse detection unit is not required.
Furthermore, by connecting the signal input / output terminals 26 of the embedded receptacle device 1 to each other, if the earthquake sensing unit of any of the connected embedded receptacle devices 1 outputs an earthquake occurrence signal, it is connected starting from itself. All embedded socket devices 1 shut off. Therefore, even if there is an embedded type outlet device 1 in which the earthquake sensing unit 21 has failed, by connecting the plurality of embedded type outlet devices 1, it is possible to reliably carry out a blocking operation that has received an earthquake.
Also, since the electric path is shut off when the tracking discharge is detected, the occurrence of a fire can be reliably prevented.
In addition, it is easy to grasp whether it is the cause of the blocking by the earthquake or tracking later by the display of the display part and it is easy to deal with it and to notify the notification sound when the electric circuit blocking mechanism part 11 operates, the resident performs the blocking operation Recognizable and easy to deal with.

In addition, although the said embodiment comprises the display part 24a by one LED, it is sufficient to provide several LED and to carry out a color display, and you may display the interruption cause by the difference in a color. In addition, when the collapse signal is output, the display unit 24a does not perform the display operation with only the buzzer sound, but the emission display may be performed in a form different from earthquake detection or tracking detection.
Furthermore, an overcurrent detection unit or a short circuit current detection unit may be provided for the electric path L, and a function similar to that of the branch circuit breaker may be added.
