Abstract

편향요크는 수평편향코일에 의해 음극선관의 전/후 및 튿방에 발생하는 누설자계를 감쇄하도록 장착한 누설자계 방지코일에 인가되는 전류를 공급하기 위하여, 별도의 환형코어를 사용하지 않고, 편향요크의 수평축으로부터 0∼70°의 각도를 이룬 상태로 페라이트 코어를 감싸도록 권선된 유도코일을 구비함으로써, 누설자계 방지코일을 수평단에 직렬 연결하거나 환형코어를 사용하는 경우에 비하여 개발 생산공정을 단순화하였고, 환형코어를 제거함으로 인한 경비 절감을 달성하였다. 이것은 누설자계 방지장치를 장착한 모든 편향요크에 유용하다.The deflection yoke does not use a separate annular core in order to supply a current applied to the leakage magnetic field prevention coil mounted to attenuate the leakage magnetic field generated before, after and after the cathode ray tube by the horizontal deflection coil. By induction coil wound around the ferrite core at an angle of 0 to 70 ° from the horizontal axis of the circuit, the development and production process is simplified compared to the case where a leakage magnetic field coil is connected in series to a horizontal stage or an annular core is used. In addition, cost savings were achieved by removing the annular core. This is useful for all deflection yokes equipped with leakage magnetic field suppressors.
