Abstract

The present invention relates to apparatus for detecting load using the electromagnetic induction. The present invention has the effect that the user may be not turned off the power source of the operating devices in carelessly as displaying the operating status of the load by the inducted current occurred in the inducted current generator. The present invention consists a load detecting meaning for detecting the operating status of load of the power line and as above said current converter using the electromagnetic induction as operating load; and a display meaning for representing the operating status of the detected load by as above said load detecting meaning. The present invention is used the detecting load using electromagnetic induction.

Description

Apparatus for Detecting Load using Electromagnetic Induction
Technical Field
This invention relates to apparatus for detecting load, and in particularly, relates to apparatus for detecting load using electromagnetic induction for detecting the operating status of the load as representing the operating status of the load in a display meaning.
Background Art
Fig. la and Fig lb depict the connection diagram of the conventional apparatus of the power connection. First, the conventional apparatus in accordance with the field of the invention is followed.
As illustrated with Fig. la and Fig. lb, in case that the connected power cord by using the conventional electric outlet becomes raveled with each other, the discrimination of the operating status of the load is impossible from the power connection meaning. In particularly, as illustrated with Fig. lb, in case that the multiple power cord by using the multi-tap become raveled, the discrimination of the operating status of the load is more impossible from the power connection meaning (in example, the power cord, the electric outlet, the multi-tap). As result, the case that the user isolates the power source as detaching the special power cord from the electric outlet or the multi-tap is frequently occurred.
In particularly, in case that the detached power cord by mistake is the power cord of the operating computer, the conventional apparatus has the problem as the damage of the hard-disc or the system file by isolating sudden power source.
Disclosure of Invention
The present invention is represented for overcoming the problem as above said, and has the object that supplies an apparatus for detecting load using the electromagnetic induction for displaying the operating status of the load by using the electromagnetic induction.
