Abstract

본 발명은 이중보조코일을 구비한 편향요크장치에 관한 것으로, 수상관이 대형화되는 추세에 맞춰 수상관 스크린에서 발생되는 래스터 디스토션과 미스컨버젼스 현상을 해소하기 위한 것이다. 이와 같은 본 발명은 편향요크(10)에 권선되어 있는 주편향코일(11) 내측에 편향요크(10)의 관축을 중심으로 일정 권선각(θ₁)(θ₂)의 범위내에 각각의 전원(20′)(21′)을 가지는 이중보조코일(20)(21)이 권선되어 구성된다. 이와 같은 본 발명에 의하면 대형 또는 평면스크린을 가지는 수상관에 있어서 래스터디스토션과 미스컨버젼스를 용이하게 보정할 수 있는 이점이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deflection yoke device having a double auxiliary coil, and to solve a raster distortion and a misconvergence phenomenon occurring in a water tube screen in accordance with a trend of an enlarged water tube. In the present invention as described above, each power source within a range of a constant winding angle θ ₁ and θ ₂ around the tube axis of the deflection yoke 10 inside the main deflection coil 11 wound around the deflection yoke 10. The double auxiliary coils 20 and 21 having 20 'and 21' are wound. According to the present invention as described above, there is an advantage of easily correcting raster distortion and misconvergence in a water pipe having a large or flat screen.
