摘要： A deflection yoke is provided for a CRT, which includes horizontal and vertical deflection coils that deflect electron beams emitted from an electron gun in a horizontal or vertical direction, a ferrite core that reduces a loss of magnetic force caused by the horizontal and vertical deflection coils thereby enhancing magnetic efficiency, and a holder that holds the horizontal deflection coils, the vertical deflection coils, and the ferrite core at required positions, and provides insulation between the horizontal deflection coils and the vertical deflection coils. The horizontal and/or vertical deflection coils have a substantially rectangular shape on a screen side, and the ferrite core is circular or elliptical. This reduces material costs and reduces convergence and distortion errors, because a dimensional distribution of an inside surface area of the ferrite core is reduced with respect to related art deflection yokes, and polishing of an inside surface becomes easier. This significantly improves production yield and the dimensional distribution of the ferrite core.

摘要： The present invention discloses a cathode ray tube including a deflection yoke which can remarkably decrease a leakage magnetic field. In the deflection yoke, a diameter of an end of a ferrite core to a screen side is 50% to 85% of a diameter of an end of a horizontal deflection coil to the screen side, and an interval between the end of the horizontal deflection coil to the screen side and the end of the ferrite core to the screen side is 27% to 50% of a length of the horizontal deflection coil in a tube axis direction. As a result, the cathode ray tube can overcome problems of general cancel coils, and reduce the leakage magnetic field even at a high deflection angle.

摘要： A deflection yoke for a Braun tube includes a primary 4-pole convergence yoke adapted to be positioned at a neck portion of a funnel of a Braun tube and a secondary 4-pole convergence yoke positioned in the vicinity of the funnel where horizontal and vertical deflection coils and a ferrite core are installed, for correcting a misconvergence generated due to the primary 4-pole convergence yoke, wherein at least one of the vertical and the horizontal deflection coils is wound at a first holder, and the secondary 4-pole convergence yoke is installed as an auxiliary coil wound on at least one side of the inner side or the outer side of the first holder. With this construction, occurrence of an inverse-magnetic field due to an induced magnetic field is prevented and thus a misconvergence can be easily corrected.
