CONSTITUTION: The sub-socket device includes a case body(101). The case body(101) has an assistant plug(102) and at least one assistant sock device(103), for allowing electrical connection corresponding to a socket buried in a wall in order to receive a commercial alternating current power and a plug of a device side power supply code for supplying power to electronic devices. The case body(101) includes a main power switching means for connecting or cutting off the power supply line connected to the plug(102) and the sock device(103), a means for removing electronic waves from the power supply line, a means for cutting off excessive voltage introduced from the power supply line, and a means for cutting off excessive current flowing into the device side via the supply power line.
