In addition, the conventional outlet has been inconvenient to check the power consumption of the electrical appliance used to be connected to the outlet.

In addition, the conventional outlet has a problem that it is difficult to check the position of the terminal insertion port at night, it is difficult to accurately insert the connection terminal portion of the plug into the terminal insertion hole.

In order to prevent accidental electric shock during use, Korean Patent Registration No. 1435339 has been proposed for 'shutter opening and closing safety outlet'.

Korean Patent Registration No. 1415339, 'Shutter-opening safety outlet' includes a shutter for opening and closing the plug insertion part of the outlet and a shutter operation means for fixing or releasing the shutter to close the plug insertion part of the outlet to prevent accidental electric shock. prevent.

However, Korean Patent Registration No. 1415339 'Shutter-opening safety outlet' requires not only closing the plug fitting with the shutter and locking the shutter with the shutter operation means when it is not in use, but also hassle of opening the shutter again after unlocking the shutter. There was this.

In other words, in order to supply power to an electric apparatus using an outlet, the shutter closing the plug fitting part must be opened, and when the plug is not in use, the shutter must be closed to prevent the plug from being coupled to the plug fitting part.
