The mounting structure of the temperature sensor 54 will be described in detail later. The temperature sensor 54 measures the temperatures of the blade receiving spring blocks 42a and 42b, and transmits the measurement results to the substrate 120 via the signal lines 60a and 60b.

  The substrate 120 is a circuit board on which a pattern wiring (not shown) is formed. A control unit 122 is mounted on the substrate 120. In the present embodiment, the control unit 122 is mounted on the back surface of the substrate 120. Based on the measurement result transmitted from the temperature sensor 54, the controller 122 determines whether or not the temperature of the blade receiving spring blocks 42a and 42b exceeds a predetermined threshold temperature. Then, the control unit 122 determines that the outlet 10 is in an overheated state when the temperature of at least one of the blade receiving spring blocks 42a and 42b exceeds a predetermined threshold temperature, and connects the switching unit described later to the opening / closing unit via the signal line 60c. Send an activation signal.

  Here, the predetermined threshold temperature can be set to 100 ° C. to 150 ° C., for example. The predetermined threshold temperature can be set according to the heat resistant temperature of the resin material constituting the outlet body cover 12 and the body member 44 of the outlet 10. Further, the predetermined threshold temperature may be changed according to the environmental temperature (or ambient temperature) where the outlet 10 is used. Further, a buzzer device may be mounted on the substrate 120 as a part of the notification unit. When it is determined that the temperature of at least one of the blade receiving spring blocks 42a and 42b exceeds the predetermined threshold temperature and the controller 122 is in an overheated state, the controller 122 turns on or blinks the abnormal lamp light emitting unit 136 and turns on the buzzer device. The notification operation may be performed by ringing. Furthermore, for example, melamine resin, urea resin, polybutylene terephthalate (PBT), or the like is suitably used as a resin material constituting the cover member such as the outlet body cover 12 and the body member 44.

  The control unit 122 in the present disclosure is preferably configured by a computer. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor is not limited as long as the function can be realized by executing the program.

The plurality of electronic circuits may be integrated on one chip or provided on a plurality of chips. The plurality of chips may be integrated into one device or may be provided in a plurality of devices. The program is recorded on a non-transitory recording medium such as a ROM, an optical disk, or a hard disk drive that can be read by a computer. The program may be stored in advance in a recording medium, or may be supplied to the recording medium via a wide area communication network including the Internet.

  As shown in FIG. 6, two signal lines 62 a and 62 b extend from the back surface of the substrate 120. Via these signal lines 62a and 62b, a signal indicating the measurement result by the temperature sensor 54 and the operating state (closed state or open state) of the switching unit 70 is transmitted to a power control device or a distribution board outside the outlet 10. May be.

  In the present embodiment, the substrate 120 is described as an example having a function of detecting an overheated state of the outlet 10 as an abnormality, but is not limited thereto. The outlet may have a seismic function that shuts off the power supply when an earthquake having a predetermined seismic intensity or more is detected as abnormal. In this case, the seismic intensity may be constituted by a seismic sensor capable of detecting acceleration, such as a gyro sensor, which is installed on the substrate or other part inside the outlet. The seismic sensor is connected to a control unit on the substrate via a pattern wiring on the substrate or a signal line. The control unit outputs an operation signal to the opening / closing unit 70 when it is determined that the earthquake is greater than a predetermined seismic intensity based on the input from the seismic sensor. Moreover, the outlet according to the present disclosure may be provided with such a seismic detection function and the above-described overheat detection function, or may be provided with a seismic function alone. Furthermore, the outlet according to the present disclosure may include a leakage detection function for cutting off a current when an leakage is detected as an abnormality in combination with the above-described overheating or seismic sense or alone. What is necessary is just to set it as the structure which provides an electric current sensor in an outlet socket in order to detect an electric leakage, and operates an opening-and-closing unit when the electric current which flows through a blade receiving spring block exceeds a predetermined threshold current value.

Become.

  As shown in FIG. 7, the actuating member 79 is disposed adjacent to the support lever 76 and the actuating plate 77, and is provided on the side wall surface of the housing 72 in the width direction so as to be rotatable about the shaft portion 79 a. The rear end portion (lower end portion in FIG. 7) of the actuating member 79 is urged by the press contact spring 80. As a result, the actuating member 79 is urged by the pressure contact spring 80 in a direction to rotate counterclockwise in FIG.

  The actuating member 79 is provided such that a substantially central portion in the front-rear direction Y can be engaged with the L-phase movable terminal plate 81. One end of the L-phase movable terminal plate 81 is electrically and mechanically connected to the other end of the L-phase conducting wire 54a by soldering or the like. In addition, an L-phase movable terminal portion 82 is fixed to the other end of the L-phase movable terminal plate 81 by caulking or the like, for example.

  The L-phase movable terminal plate 81 is held by the operating member 79 at a position rotated in the clockwise direction against the urging force of the pressure contact spring 85. As a result, when the actuating member 79 is rotated counterclockwise by the urging force of the press contact spring 80 as will be described later, the L-phase movable terminal plate 81 is released from being pressed by the actuating member 79, so that the press contact spring 85. It can be pushed up by the urging force.

  Further, the actuating member 79 presses an intermediate portion of the N-phase movable terminal plate 83. An N-phase movable terminal portion 84 is fixed to the other end of the N-phase movable terminal plate 83 by caulking, for example. As will be described later, when the actuating member 79 rotates counterclockwise, the N-phase movable terminal plate 83 is pushed up by the rear end portion (lower end portion in FIG. 7) of the actuating member 79 and the N-phase movable terminal portion 84.

  Then, one end portion of the operating plate 77 supported by the upper end of the support lever 76 is removed, so that the operating plate 77 is pushed into a state inclined backward (downward in FIG. 8) by the pressing force of the pressing spring 78. At this time, the operation lever 71 is rotated by the reaction force of the pressing spring 78 and the biasing force of the torsion spring 90 so that the end protrudes from the front surface of the outlet 10.

  When the support lever 76 of the operating plate 77 is disengaged from the support lever 76, the operating member 79 pushed and supported clockwise by the operating plate 77 is rotated counterclockwise by the biasing force of the pressure contact spring 80. . As a result, the L-phase movable terminal plate 81 is moved by the biasing force of the pressure spring 85, and the L-phase movable terminal portion 82 is separated from the L-phase fixed terminal portion 87. At the same time, the N-phase movable terminal plate 83 moves so as to be lifted by being pushed by the actuating member 79 that rotates counterclockwise. As a result, the N-phase movable terminal portion 84 is separated from the N-phase fixed terminal portion 89. Thus, the L-phase movable terminal portion 82 and the N-phase movable terminal portion 84 are separated from the L-phase fixed terminal portion 87 and the N-phase fixed terminal portion 89, respectively, so that the switching unit 70 is switched from the closed state to the open state. As a result, the power supply to the blade receiving spring blocks 42a and 42b is cut off, and the power supplied from the outlet 10 to the load such as home appliances through the plug is turned off. When the abnormal state is released and the operation lever 71 is manually returned from the state shown in FIG. 8 to the state shown in FIG. 7, the components in the opening / closing unit 70 are also shown in FIG. 7 from the state shown in FIG.
