도 3 및 도 4를 참조하면, 본 고안에 따른 편향요크의 디스토션 보정장치는 도 1에 나타낸 바와 같이 편향요크(10)는 네크부(12)와 스크린부(14)로 이루어지는 코일세퍼레이터(16)의 내측에 수평편향코일(H1)(H2)이 감겨지고, 외측으로 수직편향코일(V1)(V2)이 감겨진 페라이트코어(18)가 코어클램프(20)에 의해 조립된다.3 and 4, the deflection yoke distortion correction apparatus according to the present invention, as shown in Figure 1, the deflection yoke 10 is a coil separator 16 consisting of a neck portion 12 and the screen portion 14 A horizontal deflection coil (H1) (H2) is wound on the inside of the ferrite core 18 wound around the vertical deflection coil (V1) (V2) is assembled by the core clamp (20).

상기 보정부재(22)(24)는 양측으로 돌출편(26)(28)이 형성되어 연결편(30)으로 연결된다.The correction members 22 and 24 are protruding pieces 26 and 28 formed at both sides thereof, and are connected to the connection piece 30.
또한, 상기 보정부재(22)(24)의 돌출편(26)(28)에는 보정코일(XH-C1)(XH-C2)이 복수가닥으로 감겨져 수평편향코일(H1)(H2)에 연결되고, 상기 보정코일(XH-C1)(XH-C2)은 가변저항(VR)에 병렬로 각각 연결된다.Further, correction coils X H- C 1 (X H -C 2) are wound in a plurality of strands on the protruding pieces 26 and 28 of the correction members 22 and 24, respectively, to the horizontal deflection coils H 1 and H 2.
