Abstract

본 발명은 인라인 전자총을 갖는 칼라 브라운관용 편향요크에 관한 것으로써, 좀더 구체적으로는 평면 칼라 브라운관에서 나타나는 상, 하 핀쿠션 디스토션을 보정할 수 있도록 한 것이다.The present invention relates to a deflection yoke for a color CRT tube having an inline electron gun, and more specifically, to correct the upper and lower pincushion distortion shown in a flat color CRT.

이를 위해, 8자형으로 권회된 보조코일(9)을 홀더(5)의 내측면에 대칭되게 고정함과 동시에 상기 보조코일(9)을 수평 편향코일(2)과 직렬로 연결하여 수평 편향코일의 개구부(9a)에서 상기 수평 편향 코일의 자계장(11)방향과 반대방향의 자계장이 형성되도록 하고, 중간부에서는 상기 수평편향코일의 자계장방향과 같은 방향의 자계장이 형성되도록 하여서 된 것이다.To this end, the auxiliary coil 9 wound in an eight-shape is symmetrically fixed to the inner surface of the holder 5 and at the same time the auxiliary coil 9 is connected in series with the horizontal deflection coil 2 to provide a horizontal deflection coil. The magnetic field in the direction opposite to the magnetic field 11 direction of the horizontal deflection coil is formed in the opening 9a, and the magnetic field in the same direction as the magnetic field direction of the horizontal deflection coil is formed in the middle portion.
