본 고안은 편향 요크의 코일 권선용 금형에 관한 것으로서, 더욱 상세하게는 음극선관에 있어서, 적, 녹, 청의 각색광에 대응하는 전자비임을 편향시키는 새들형 코일을 용이하고 정확하게 보정하여 제작토록 한 편향 요크의 코일 권선용 금형에 관한 것이다.The present invention relates to a coil winding die of a deflection yoke, and more particularly, in a cathode ray tube, a saddle coil for deflecting an electron beam corresponding to red, green, and blue color light is easily and accurately compensated for deflection. A yoke coil winding die.
일반적으로 음극선관의 편넬부에 부착되어지는 편향요크는 크게 반나팔체상의 세퍼레이터와 세퍼레이터의 내측및 외측에 부착되는 새들형의 수평코일과 페라이트 코어에 권선되는 수직코일과, 편향요크를 네크부에 고정시키는 고정부로 나누어진다.In general, the deflection yoke attached to the cathode portion of the cathode ray tube is divided into a semi-permanent separator, a saddle-shaped horizontal coil attached to the inside and the outside of the separator, a vertical coil wound around the ferrite core, and a deflection yoke on the neck. It is divided into fixing parts for fixing.
상기한 새들형 코일은 인라인형의 전자총에서는 수평코일에 사용되어지고, 델타형의 전자총에서는 수평 및 수직코일에 사용되고 있다.The saddle coil is used for horizontal coils in inline electron guns and horizontal and vertical coils in delta electron guns.
전자총에서 발사된 3줄의 전자비임은 전자렌즈에 의해 집속되고 스크린과 대향 설치된 새도우 마스크 구멍을 통하여 전자비임이 형광체에 부딪쳐 화상이 나타나게 된다.The three rows of electron beams emitted from the electron gun are focused by the electron lens, and the electron beam hits the phosphor through a shadow mask hole opposite to the screen, resulting in an image.
이때의 화상을 크로스 패턴상태에서 보면 적, 녹, 청의 비임이 한점에 접속되지 않고 흩어져 있게 된다.When the image at this time is viewed in a cross pattern state, the beams of red, green, and blue are scattered without being connected to one point.
이러한 현상이 미스 콘버젼스인데 이는 브라운관내에 전자총 장착이 정위치에 되지 않던가 아니면 전자총의 비임통과 구멍의 간격이 잘못 형성되면 발생되게 된다.This is a misconvergence, which occurs when the gun is not mounted in the CRT or the gap between the non-passage and the hole of the gun is incorrectly formed.
이러한 미스 콘버젼스를 보정하기 위하여 편향요크의 편향코일을 수정하게 된다.In order to correct this misconvergence, the deflection coil of the deflection yoke is modified.
상기 편향코일중 수평코일은 새들형상으로 권선되어 부착되는데 제3도에 나타낸 바와 같이 핀구션 자계를 형성하는 개구부(A)와 배럴형 자계를 형성하는 네크부(B)와 균일한 자계를 형성하는 중간부(C)로 이루어진다.Among the deflection coils, the horizontal coil is wound and attached to the saddle shape, and as shown in FIG. 3, the opening A forms the pincushion magnetic field and the neck portion B forming the barrel magnetic field, and forms a uniform magnetic field. It consists of an intermediate part (C).
이 자계들의 영향으로 미스 콘버젼스 및 상하 왜곡 현상이 발생되는데 미스 콘버젼스의 영향은 중간부(C)에서 대부분 발생되고, 상하 왜곡현상은 개구부(A)의 영향이 크나전체 자계분포에 따라 영향을 주므로 권선시에 세심한 주의를 요하게 되며 코일을 권선하는 금형의 수정이 필수적으로 된다.The effects of these magnetic fields cause miss convergence and vertical distortion. Most of the influence of the miss convergence occurs in the middle part C, and the vertical distortion phenomenon is largely influenced by the opening A. Because of the influence, it requires careful attention in winding and modification of the mold winding the coil is essential.
종래 편향요크의 코일 권선용 금형은 제4도에 나타낸 바와 같이 코아(D)가 돌출 형성된 자형 금형(E)에 요흠(F)가 형성된 웅형 금형(G)를 결합하여 공간에 코일을 권선하도록 하는 분할형 금형이 사용되고 있다.Conventional deflection yoke coil winding die is divided into a male mold (E) formed with a core (E) protruding core (D) as shown in FIG. Mold molds are used.
상기한 금형은 코일의 각부분 또는 한 부분을 수정할 필요가 있을 때에는 조립된 금형을 분해한다음 덧붙임 용접등의 작업을 한후 저하될 뿐만아니라 금형의 조립은 정밀한 작업을 요하므로 시간적으로 손실을 가져오고 수정부분에 대한 정확도도 떨어진다고 하는 문제점이 있다.When the above-mentioned mold needs to modify each part or one part of the coil, it disassembles the assembled mold and then deteriorates after the work such as welding. Furthermore, as the assembly of the mold requires precise work, it causes time loss. There is a problem that the accuracy of the modified portion is also poor.
본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로 본 고안의 목적은 수정부분에 대한 정확한 수정이 용이하고 작업능률이 향상된 편향요크의 코일권선용 금형을 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above is an object of the present invention is to provide a mold for the coil winding of the deflection yoke easy to correct the corrected portion and improved work efficiency.
