发明名称 Deflection yoke for braun tube and fabrication method thereof
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.
