일반적으로 편향요크는 음극선관의 전자총에서 발사된 전자빔을 좌·우측 및 상·하측으로 편향시켜 음극선관의 형광면 상에 형성된 RGB에 충돌시키는 역할을 하는 것으로서, 도 1에 나타낸 바와 같이 전자빔을 편향시키는 수평편향코일(미 도시됨)과 수직편향코일(4)의 조합으로 구성되며, 이분 형성된 세퍼레이터(2) 내주면에 수평편향코일(미 도시됨)이 설치되고 상기 세퍼레이터(2)의 외주면에 수직편향코일(4)이 설치된다.In general, the deflection yoke deflects the electron beam emitted from the electron gun of the cathode ray tube to the left, right side, and the upper side and the lower side and collides with the RGB formed on the fluorescent surface of the cathode ray tube. Composed of a combination of a horizontal deflection coil (not shown) and a vertical deflection coil (4), a horizontal deflection coil (not shown) is installed on the inner peripheral surface of the separator (2) formed in two parts and vertical deflection on the outer peripheral surface of the separator (2) Coil 4 is installed.

또한, 수직편향코일(4)의 자계를 보강하기 위해 상기 세퍼레이터(2)의 외주면에 서로 분할된 한쌍의 페라이트코어(5)가 장착되며 세퍼레이터(2)의 외주면 후단에 돌출 형성된 지지돌편(3)에 의해 고정된다.In addition, in order to reinforce the magnetic field of the vertical deflection coil 4, a pair of ferrite cores 5, which are divided with each other, is mounted on the outer circumferential surface of the separator 2 and protrudes at the rear end of the outer circumferential surface of the separator 2.

이러한 종래 기술에 따른 편향요크의 페라이트코어 고정구조에 의하면, 상기 페라이트코어(5)를 세퍼레이터(2)의 외주면에 장착·고정시 지지돌편(3)의 지지력이 약하여 외부의 충격 또는 흔들림으로 인한 페라이트코어(5)의 유동이 발생할 수 있으므로 컨버전스의 조절이 용이하지 못하여 편향요크의 특성을 저하시키는 문제점이 있었다.According to the ferrite core fixing structure of the deflection yoke according to the prior art, the support force of the support stone piece 3 is weak when the ferrite core 5 is mounted on the outer circumferential surface of the separator 2 so that the ferrite core may be caused by external impact or shaking. Since the flow of the core 5 may occur, it is not easy to adjust the convergence, and thus there is a problem of lowering the characteristics of the deflection yoke.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적으로 하는 바는 세퍼레이터의 외주면 후단에 서로 대응되어 돌출 성형된 한쌍의 고정돌기를 형성하고 상기 고정돌기의 좌·우측 상부에 서로 대응되어 돌출 성형된 한쌍의 누름편을 각각 형성하여 페라이트코어를 이중으로 눌러줌으로써 외부의 충격 또는 흔들림으로 인한 페라이트코어의 유동을 방지하여 컨버전스의 조절을 용이하게 하고 편향요크의 특성이 안정되도록 하는데 있다.Accordingly, the present invention has been proposed to solve the above problems, and its purpose is to form a pair of fixing protrusions protrudingly formed to correspond to each other at the rear end of the outer circumferential surface of the separator and to each other on the upper left and right sides of the fixing protrusions. Correspondingly, by forming a pair of pressing pieces each protrudingly formed to press the ferrite cores in a double way to prevent the flow of the ferrite cores due to external impact or shaking to facilitate the control of convergence and to stabilize the characteristics of the deflection yoke. .
