Abstract
PURPOSE: To obtain easily magnetic deflecting yoke which does not generate distortion by dividing the bell shaped core in the direction of length and winding, separately on each division, coils which generate barrel magnetic field and pin- cushion magnetic field.
CONSTITUTION: The core 13 having bell form as a whole is arranged on the vertically deflecting coil 14 of a magnetic deflecting yoke, and is divided into half in the longitudinal direction and on the small diameter side division core 13P, a coil 14P is wound, so that deflecting magnetic field distribution form barrel magnetic field, and on the large diameter side division core 13H, a coil 14H is wound so that deflection magnetic field distribution forms pin-cushion magnetic field, in triodal winding by a conventional winding machine. After that, cores 13P and 13H having coils 14P and 14H wound respectively are formed in combination in front and in rear and connected by allowing a connecting metal fitting 16 to be pressure-fitted into the concaved parts 15P and 15H formed on the cores, and said coils 14P and 14H are connected, and a vertical deflecting coil is constituted. Thus, through the combination with inline type cathode-ray tube, a magnetic deflecting yoke which displays correct raster on the screen can be obtained easily.
