DEFLECTION YOKE

摘要

PURPOSE: A deflection yoke is provided to prevent a change of a deflection property due to an assembly distribution by assembling strongly a ferrite core with a simple assembly structure. CONSTITUTION: A deflection yoke(4) comprises a coil separator(10) including a screen part(11) combined with one side of a screen surface of a cathode ray tube and a neck part(13) combined with an electron gun part of the cathode ray tube; a horizontal and a vertical deflection coil(16) for forming a horizontal and a vertical deflection magnetic field; a ferrite core(14) of a magnetic substance for strengthening a magnetic field and surrounding an outer circumference of the vertical deflection coil; and a coupling device provided on an outer circumference of the ferrite core being adjacent to the screen part in such a manner that the ferrite core is fixed to the screen part.
