Abstract

PURPOSE: To facilitate the pincushion correction of a cathode tube by providing a vertical deflection coil in the troidal winding fashion for the core of a deflection yoke provided inside thereof with a saddle-wound horizontal deflection coil.
CONSTITUTION: A troidal coil is wound in three separate coils on a semicircular ferrite core 11a obtained by splitting a funnel-shaped ferrite core 11 into two parts along the axis of the funnel. In the central portion of the ferrite core 11a, a first coil 13 wound between the inner circle (P) and the outer circle (H) at a regular angle and a second and third coils 14 and 15, respectively, simmetrically wound with respect to the first coil 13 are provided. The second coil 14 and the third coil 15 are wound divergently on the inner circle (P) and convergently on the outer circle (H). The coils 13, 14 and 15 are connected in series.
