Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an outlet box,

The present invention relates to an outlet box for a wall-mounted apartment house, and more particularly, to an outlet box for a wall-mounted apartment, more specifically, an outlet box in which a plug is coupled, It is possible to prevent a safety accident such as an electric shock accident of a human body caused by an infant or the like due to exposure of an outlet terminal port by conducting electricity and to easily find an outlet hole into which a plug is inserted, .

Generally, a receptacle (Concent) is a mechanism to insert a plug by connecting it to a wiring to connect a cord used indoors in an electric indoor wiring. The outlet is installed on the wall, the floor, etc., and there are the exposed type and the buried type. The rated voltage is 110V or 220V and the rated current is 10 ~ 50A depending on the electronic and electric devices used. Usually, one or more plugs can be plugged for 10A. The outlet is equipped with a grounding terminal to prevent electric shock such as washing machine, a waterproof type such as outdoor and bathroom, a plug used for refrigerator, And so on.

Conventional receptacles may be connected to a terminal of an electric wire connected from an indoor wiring or to an intermediate portion of a wire to be wired indoors.

In a generally known outlet used for such a purpose, power is connected to an outlet, which is a connector of the indoor wiring, to supply power to various electronic products requiring power, and the electronic product is easy to be transported and stored The plug is installed at the end of the cable so that the power is cut off when the plug is detached from the outlet, the electronic product is easily transported and stored by arranging the cable, and when the plug is connected to the outlet, .

However, according to the conventional outlet used for this purpose, even when the electric plug is not connected, the outside and the inside of the outlet are electrically connected to each other. Therefore, when the electric plug is not plugged, It becomes possible to access the internal wiring, and accordingly, if a conductor such as a wire is connected to a receptacle to which the plug is not plugged, there is a possibility that an electric shock accident may occur.

That is, according to the conventional socket-outlet so far, the specification in which the terminal insertion port to which the plug is inserted is the main specification, and the exposure of the terminal insertion opening is a cause of trouble for children who are aware of the danger of adult or electricity For children who are not aware of the danger, the outlet itself has become a subject of great curiosity. This curiosity leads to behavior that is inserted into the terminal insert using sharp tools such as chopsticks, and tweezers or pointed tools 2 The inserted tool is connected to the connection terminal inside the receptacle, causing an electric shock accident.
