A deflection yoke has a non-magnetic conductor on a screen-bent portion or a neck-bent portion of a vertical deflection coil, and the non-magnetic conductor is connected to ground by means of a lead line for the purpose of eliminating a ringing phenomenon caused by stray capacitance between horizontal and vertical deflection coils, and the vertical deflection coil and a ferrite core, which can be adopted to any saddle-saddle type deflection yokes having saddle-shaped vertical and horizontal deflection coils. A considerable amount of the stray capacitance is passed to the ground, and the ringing phenomenon is improved.

Deflection yoke

A deflection yoke has an induction coil wrapped about its ferrite core at an angle of from 0 to 70 degrees from the horizontal axis of the deflection yoke to supply current to a leakage magnetic-field canceling coil also mounted to the deflection yoke for attenuating a leakage magnetic field produced from the front, rear and side of a cathode ray tube within the deflection yoke without using a separate circular core. This improves the operation and simplifies the production of the deflection yoke as compared to deflection yokes having the leakage magnetic-field canceling coil serially connected to the horizontal deflection coil or using a separate circular core.
