DEFLECTION YOKE FOR CATHODE RAY TUBE

摘要

PURPOSE: A deflection yoke for a cathode ray tube is provided to be capable of establishing a standard of design and laying the foundation of optimization by reducing the design factors of RAC(RectAngular Cone)-type deflection coil. CONSTITUTION: A horizontal and a vertical deflection coils deflect horizontally or vertically an electron beam emitted from an electron gun respectively. A ferrite core reduces loss of the magnetic force generated from the horizontal and the vertical deflection coil so as to increase the magnetic efficiency. A holder fixes the horizontal deflection coil, the vertical deflection coil and the ferrite core in a predetermined position, and insulates the horizontal deflection coil from the vertical deflection coil. The center(CX) of the major axis arc(31X) in the inside of the horizontal deflection coil coincides with or adjoins to the center of the major axis arc(33X) in the outside of the vertical deflection coil.
