Deflection yoke with leaking magnetic field prevention coils

摘要

The present invention is relative to a deflection yoke in which a leaking magnetic field preventing member is formed without a magnetic body, such that coil winding parts are formed opposite to and apart from each other at a predetermined distance in the inside of a case formed in the same curvature as that of a flange part of a separator and coils of a predetermined diameter are wound therearound at a predetermined number of turns; a current which can form the current of direction contrary to a magnetic field generated from a horizontal deflection coil supplied therewith; and a leaking magnetic field preventing member in which a cover having a plurality of heat emitting holes fixed on the case is combined with a flange part in the form of corresponding a horizontal deflecting coil by combining an attaching part of the case with a corresponding part of the flange part.
