PLUG SOCKET
First Claim
1. A plug socket comprising:
- a power-saving circuit supplying or cutting off electric power to a connected electrical device according to a load current;
a mode setting unit setting any one of an automatic mode, a manual mode, and an optional automatic mode such that the power-saving circuit is operated in the set mode;
a signal input unit connected to a jack connection unit and configured to input an operation signal to supply or cut off electric power to the power-saving circuit; and
a changeover switch unit including a button or a lever to forcibly supply or cut off electric power,wherein the power-saving circuit comprises;
a switch unit switching the input electric power so that the input electric power is supplied or cut off to the electrical device and cutting off the power supply when the signal input unit is disconnected from the jack connection unit;
a load current detection unit detecting a load current according to an operation state of the electrical device and inputting a load signal; and
a control unit controlling the operation of the switch unit in response to at least one of the mode set by the mode setting unit, the load signal, and the operation signal of the signal input unit.

Abstract
Provided is a plug socket which determines operation states of a plurality of electrical devices connected to the plug socket to supply or cut off electric power to the electrical devices and selects a method for supplying or cutting off electric power to the electrical devices by setting a desired mode. Thus, it is possible to prevent the waste of energy and electrical accidents by cutting off the electric power when the electrical devices connected to the plug socket are not used. Especially, since the electric power is supplied only when the electrical devices are used in a home network system, it is possible to efficiently use electricity, significantly reduce unnecessary power consumption, and thus the cost is reduced. Moreover, in the case of a built-in plug socket, it is possible to change the time or method for cutting off electric power by setting a desired mode according to the kind of the electrical device, and thus user convenience is significantly improved.
