And the above circuit is turned on. In the contact mechanism unit 3, the movable terminal 15f and the first terminal portion 15d are electrically insulated from each other at a position where the movable terminal 15f is separated from the first terminal portion 15d, and the circuit can be blocked. Similarly, the contact mechanism unit 3 can correspond to the operation of the operation unit 3a, and the second plug piece connecting body 15b can be in contact with the third terminal portion 15g and the second terminal portion 15e in the second plug piece connecting body 15b. And moving between the positions where the movable terminal 15f is separated from the third terminal portion 15g. In other words, the wiring device 10 is configured to switch the power supply to the load of the contact mechanism unit 3 to the on/off state in accordance with the operation of the operation unit 3a by the operator.

The operation portion 3a is provided with protruding protrusions 3d on both sides of the opposite side in the short side direction. The operation portion 3a is disposed so as to be inserted into the first through hole 11be of the first outer cover 11b, and is exposed by the third through hole 4bc of the cosmetic sheet 4. In other words, the third through hole 4bc of the cosmetic sheet 4 is filled in the operation portion 3a of the first through hole 11be of the first outer cover 11b. The projection 3d of the operation portion 3a is supported by the fifth groove provided in the first outer cover 11b. The fifth groove is configured as a bearing portion of the projection 3d. Since the operation portion 3a is rotatably supported by the fifth groove, the projection 3d can be attached to the first outer cover 11b so as to be swingable.

The wiring device 10 is disposed from the front side, and is disposed such that the operation portion 3a is positioned between the insertion opening 1c of the socket portion 1 and the handle 2d of the leakage detecting control portion 2, and is closer to the insertion handle 2d. The position of port 1c. In any of the ON position and the OFF position, the operation unit 3a causes the operation unit 3a to protrude from the surface 10aa of the wiring tool 10. The wiring device 10 is disposed closer to the insertion port 1c than the handle 2d by the operation portion 3a, so that the operator can naturally detect the handle 2d of the control unit 2 in comparison with the leakage. It is preferable to operate the operation portion 3a of the contact mechanism portion 3 first. Since the wiring device 10 is more inclined to operate the contact mechanism portion 3 than the leakage detecting control portion 2, it is easier for the operator to recognize that the circuit has leakage.

The opening and closing control unit 23 is provided with a pulling device. The driving of the pulling device allows the plate portion 25i to be pulled out from the assembly portion 25a in the shutter 25 which will be described later. The opening and closing control unit 23 is configured to detect leakage caused by a ground fault. The opening and closing control unit 23 is configured to drive the shutter 25 by a pulling device when it is detected that there is a leakage.

The leakage detecting control unit 2 can pressurize the test button 28a during energization, and the conductive contact spring 28b contacts the lead terminal of the printed circuit board 23b to artificially create a ground fault state. The leakage detecting control unit 2 outputs a signal from the zero comparator 23a when the contact spring 28b contacts the lead terminal to drive the pulling device.

The leakage detecting control unit 2 does not output a signal from the zero comparator 23a in the normal state. The leakage detecting control unit 2 outputs a signal from the zero comparator 23a at the time of a ground fault. The wiring device 10 detects that a signal from the zero-phase comparator 23a is detected, and it is possible to detect that a ground fault has occurred somewhere in the circuit from the wiring tool 10 to the external load.

In the contact portion 22, the movable contact 22b is brought into contact with the fixed contact portion 22a by the pressurization of the movable contact 22b by the movable frame 25h.

In the shutter 25, when the plate portion 25i resists the elastic force of the second spring 25k and rotates away from the frame portion 25a, one end of the rocker 25g is separated from the plate portion 25i. When one end of the rocker 25g is detached from the plate portion 25i, it rotates around the third shaft portion 25e.

The surface 10aa of the instrument 10 is moved in a direction in which it protrudes. In the shutter 25, the connecting portion 25c is pulled up as the handle 2d rotates, causing the rocker 25g to move along the guide groove 25ac of the rack portion 25a. In the shutter 25, as the rocker 25g moves, the rocker 25g loses the force of pressurizing the movable frame 25h. When the movable frame 25h is no longer pressurized by the rocker 25g, the movable contact 22b is detached from the fixed contact portion 22a, and the above circuit can be blocked.

In the first position, the handle (2d) is positioned so as not to protrude from the surface (10aa) such that the first surface (2da) and the surface (10aa) are flush with each other. In the second position, the handle (2d) is positioned at a position protruding from the surface (10aa) such that the first surface (2da) is inclined with respect to the surface (10aa). The operation unit (3a) can be configured to swing between an ON position at which the contact mechanism unit (3) energizes the circuit and an OFF position at which the contact mechanism unit (3) blocks the circuit. The operation portion (3a) protrudes from the surface (10aa) so as to be inclined with respect to the surface (10aa) regardless of the ON position or the OFF position.

The wiring device (10) of the embodiment of the present invention has an effect of further improving the operability.
