Description

Outlet {CONCENTIC PLUG}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outlet, and more particularly, to a buried type outlet installed in a wall surface of a building.

In general, an outlet refers to a device that connects a wire and inserts a plug to connect a cord used indoors in an indoor wiring of electricity, and is classified into two types, a buried type and an exposed type.

Among them, the buried type outlet is attached to the interior wall, and the current flows in order to supply the power necessary for using the electric equipment. Therefore, when the plug is not removed from the outlet after the use of the electric equipment is completed, the inserted plug There is a problem that energy is wasted due to power leakage due to the power leakage, and a standby power cut-off outlet has been developed to improve this problem.

However, the conventional standby power cut-off outlet has been limited in size of the rear, side, etc. because of a predetermined standard for a buried type outlet, so that components such as a circuit board had to be placed in the part where the plug for the power plug is to be placed.

As a result, only one outlet for standby power cut-off was placed in a two-hole outlet, and based on this concept, even if the number of outlets was expanded, the outlet having an odd number of outlets, such as three or five outlets, had to be configured. There was no.

Not only does this significantly reduce the space utilization of a receptacle with a specified size, but also generally requires that appliances be turned off after use (microwave ovens, TVs, computers, etc.) and products that must always be turned on. Even in view of the presence of refrigerators, FAX, etc. (for regular power), an outlet having only a standby power cut-off outlet is not useful.

In particular, when replacing the existing two-prong outlet with the outlet for standby power cut off, if the microwave oven and the refrigerator is connected to the existing outlet, the refrigerator needs a constant power source, so a problem arises in that a current must be supplied from a separate power source.

Therefore, there is a need for an outlet capable of increasing the space utilization by utilizing all the spaces of the outlet and having both a standby power cut-off and a regular power outlet.
