In this case, it is inconvenient to insert a plug into an outlet prepared to use another plug, or to bend the lead wire connected to the plug by force.

In addition, there is a problem that the terminal for the telephone or the TV antenna terminal for the same standard that does not have the same specifications for the outlet does not have to be used together with the power outlet and must be provided by installing a separate electric box.

The present invention was devised to solve this problem, and its purpose is to form a plug insertion hole for 110V and 220V in one outlet integrally, so that the plug can be inserted into a plug insertion hole according to the working voltage without using a separate adapter. It is to be inserted correctly.

Another object of the present invention is to form a voltage display part of the number, color, or other symbol on the outlet so that the user can visually identify the current supply voltage, thereby preventing damage to the electrical appliance due to incorrect insertion of the plug. It is to be done.

Another object of the present invention is to install a safety cover formed with a plug insertion hole for 110V and 220V to be rotatable on the front of the outlet to prevent an electric shock due to chopsticks in advance.
