Description

A plurality of DC multi-taps {Concentric plug}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of direct current multi-tapes, and more particularly, to a functional outlet that outputs a plurality of voltages from a single outlet.

BACKGROUND OF THE INVENTION [0002] The use of electrical products in offices and homes has increased, and in particular, outlets with a plurality of outlets have been widely used to use computer-related electrical appliances such as computers, printers and Internet routers. On the other hand, when a plurality of plugs are plugged into such an outlet and the main switch is turned on for use during business hours, there is a case where the plug is plugged into the outlet but the electric appliance is not used.

Even if you know that energy is wasted if you put the plug of the appliance into the outlet when the appliance is not used, you can use it by putting it under the desk with the main switch of the outlet plugged in It is very troublesome to remove the unused plug from the outlet, which is a waste of energy because it is used while the plug is plugged in.

In addition, since the outlet is placed under the desk or in the corner space even if the outlet having the individual switch is used to save energy, the user does not use the electric appliance which is not used yet while turning off the power, .

In order to solve this problem, in Korean Patent Laid-Open Publication No. 10-2000-0030155 (published on June 05, 2000), a plurality of plugs are inserted into an outlet provided with an individual switch for operating various electric products, It is equipped with a desk switch with separate switches to prevent energy wastage by turning off the power supply of unused electric appliances. A receptacle is disclosed.

However, such a conventional outlet provides only a single voltage, for example, a commercial voltage of 220V, and therefore, when the voltage is changed and used, a separate voltage conversion adapter according to each required voltage has to be used.
