Description

Wiring appliances

The present invention relates to a wiring device used for embedding a building material such as a wall, and more particularly, to a wiring device that blocks a circuit when a leakage current is detected.

Conventionally, a power outlet having a function of detecting a leakage of a circuit and blocking it has been conventionally known for wiring appliances (see, for example, Document 1 [Japanese Laid-Open Patent Publication No. 2006-48958]).

Although the power outlet of Document 1 has a built-in earth leakage circuit breaker, there is no record about the situation after the circuit is blocked by the earth leakage circuit breaker.

In addition, as for the wiring device, I want a wiring device with higher usability, and I hope that the user can more easily and surely recognize a state in which a leakage current is detected and the circuit is interrupted.

In view of the above problems, an object of the present invention is to provide a wiring appliance with higher usability.

The wiring device of the present invention includes a socket portion having an insertion opening through which a pin of a plug can be inserted, and a leakage detection control unit having a contact portion provided in a circuit through which the circuit is inserted into the socket portion. The plug supplies power to the load from an external power source; a shutter that opens and closes the contact portion; an opening and closing control portion that detects a leakage current of the circuit and controls the shutter to open the contact portion; and The handle is displaced in conjunction with the opening and closing of the contact portion. The insertion port and the handle are disposed on a surface of the wiring appliance. The handle is configured to be rotatable between a first position where the shutter closes the contact portion and a second position where the shutter opens the contact portion. This handle has a flat first surface. The first position is a position where the handle does not protrude from the surface so that the first surface forms the same plane as the surface. The second position is a position where the handle protrudes from the surface in such a manner that the first surface is inclined with respect to the surface.

The insertion port (1c) and the handle (2d) are provided on a surface (10aa) of the wiring device (10). The handle (2d) constitutes a first position where the shutter (25) can close the contact portion (22) and the shutter (25) A structure in which the contact portion (22) is rotated between the second positions that are disconnected. The handle (2d) includes a flat first surface (2da). The first position is a position where the handle (2d) does not protrude from the surface (10aa) so that the first surface (2da) and the surface (10aa) form the same plane. The second position is a position where the handle (2d) protrudes from the surface (10aa) such that the first surface (2da) is inclined with respect to the surface (10aa).

The wiring device (10) according to the second aspect of the present invention is the first aspect, wherein the handle (2d) is provided with a protrusion protruding from the first surface (2da) with respect to the surface (10aa). In the state, the second surface (2db) is flush with the surface (10aa). In other words, the handle (2d) includes a flat second surface (2db) different from the first surface (2da). The second surface (2db) forms the same plane as the surface (10aa) at the second position.

The wiring device (10) according to a third aspect of the present invention is the second aspect, wherein the wiring device (10) has a window portion (21ba) that exposes the handle (2d) on the surface (10aa). The first position is such that the handle (2d) is exposed from the window portion (21ba) with the first surface (2da) and the second surface (2db) is not exposed from the window portion (21ba). A position protruding from the window portion (21ba). The second position is such that the handle (2d) is inclined from the window portion such that the first surface (2da) is inclined relative to the surface (10aa) and the second surface (2db) is exposed from the window portion (21ba). (21ba) protruding position.

A fourth aspect of the wiring device (10) of the present invention is the second or third aspect, wherein the handle (2d) is provided to be connected to the first surface (2da) and the second surface (2db), The third surface (2dc) extends in a direction perpendicular to the second surface (2db).

In other words, the handle (2d) has a third surface (2dc) that connects the first surface (2da) and the second surface (2db). The third surface (2dc) extends along the normal direction of the second surface (2db).

The wiring device (10) according to the embodiment of the present invention has the effect of further improving usability.
