본 고안은 편향요크에 관한 것으로서, 더욱 상세하게는 음극선관의 스크린 앞에 형성되는 누설방사자계를 차폐시키도록 한 편향요크에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to a deflection yoke for shielding a leakage radiation field formed in front of a screen of a cathode ray tube.

편향요크는 반나팔체상을 갖는 1쌍의 세퍼레이터의 내측에 수평편향 코일이 위치되고, 그 외측에는 페라이트 코어에 권선된 수직편향코일이 배치되어 이루어지는 것으로서 음극선관의 네크부에 장착된다.In the deflection yoke, a horizontal deflection coil is positioned inside a pair of separators having a half-tornel shape, and a vertical deflection coil wound around a ferrite core is disposed outside the deflection yoke and is mounted on the neck portion of the cathode ray tube.

이와 같은 편향요크에 수직 및 수평 주사용 톱니파 전류를 흘리게 되면 음극에서 주사되는 전자비임은 편향요크에서 발생되는 편향자계에 의해 상하 및 좌우로 편향되어 스크린상에 라스터를 그리게 된다.When a vertical and horizontal scanning sawtooth current flows through such a deflection yoke, the electron beam scanned from the cathode is deflected up and down and left and right by a deflection magnetic field generated in the deflection yoke to draw a raster on the screen.

그런데 편향요크에서 발생되는 편향자계는 수평편향 코일에서 형성되는 수평편향자계와 수직편향 코일에서 발생되는 수직편향자계로 형성되는데, 이중에서 수평편향 자계는 인체에도 유익하지 않고 비임의 편향에도 불필요한 방사자계를 스크린의 앞쪽에 형성시키고 있다.However, the deflection magnetic field generated in the deflection yoke is formed of the horizontal deflection field formed in the horizontal deflection coil and the vertical deflection field generated in the vertical deflection coil, of which the horizontal deflection magnetic field is not beneficial to the human body and is unnecessary for the deflection of the beam. Is formed at the front of the screen.

종래에, 상기한 바와 같은 스크린의 앞쪽에 형성되는 불필요한 누설방사자계를 감소시키기 위하여 제 3 도에 나타낸 바와 같이 사각형상의 페라이트 코어(F)에 감겨진 코일(C)을 편향요크(D)의 개구부측에 부착시키고 있으나, 이는 편향요크(D)의 중앙선상에 위치되므로 인하여 스크린 앞의 좌우에 형성되는 누설자계등의 전반적인 누설방사자계까지 상쇄시킬 수 없는 단점이 있다.Conventionally, the opening of the deflection yoke D is provided with the coil C wound around the rectangular ferrite core F as shown in FIG. 3 in order to reduce unnecessary leakage radiation fields formed in front of the screen as described above. It is attached to the side, but because it is located on the center line of the deflection yoke (D) there is a disadvantage that can not cancel the overall leakage radiation field, such as the leakage magnetic field formed on the left and right in front of the screen.

또, 제 4 도에 나타낸 바와 같이 음극선관(T)의 네크부에 장착된 편향요크(D)의 전면부로 페라이트 링(R)을 설치하여 누설자계를 감소시키도록 하고 있으나, 이는 수동적인 것으로 수평주파수에 따라서 저주파수일때는 고투자율을, 고주파수일때는 저투자율의 링을 사용해야 하고 번거롭게 위치조절해야 하는 문제점이 있다.In addition, as shown in FIG. 4, the ferrite ring R is installed to the front portion of the deflection yoke D mounted on the neck portion of the cathode ray tube T to reduce the leakage magnetic field. Depending on the frequency, high permeability at low frequencies and low permeability rings at high frequencies have to be troublesome.

본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 음극선관의 스크린 앞에 형성되는 불필요한 누설 방사자계를 차폐시키는 편향요크를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a deflection yoke for shielding the unnecessary leakage radiation field formed in front of the screen of the cathode ray tube.

상기한 바와 같은 목적을 실현하기 위하여 본 고안은 음극선관의 네크부에 장착되어 음극에서 주사되는 전자비임을 편향시키는 편향요크에 있어서, 수평편향 코일의 라운드부가 위치되는 개구부측 선단에 단면 "자상으로된 1쌍의 페라이트제 차폐판을 부착 설치한 편향요크를 제공한다.In order to achieve the above object, the present invention is a deflection yoke mounted on the neck portion of a cathode ray tube and deflects an electron beam scanned from a cathode. Provided is a deflection yoke provided with a pair of ferrite shielding plates.

이하에, 본 고안의 바람직한 실시예를 첨부된 도면에 따라서 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

제 1 도는 본 고안의 편향요크를 나타내는 일부 분해 사시도로서, 부호(1)은 편향 요크를 나타내고 있다.1 is a partially exploded perspective view showing a deflection yoke of the present invention, and reference numeral 1 denotes a deflection yoke.

상기한 편향요크(1)는 1쌍의 반나팔체상 세퍼레이터(2)의 내측에 수평편향코일(3)이 그 플레어(3')가 외측방으로 놓이게 배치되고, 또 상기 세퍼레이터(2)의 외측에는 페라이트 코어(4)를 심재로 하여 감겨진 수직편향코일(5)이 부착되어 있다.In the deflection yoke 1, the horizontal deflection coil 3 is disposed inside the pair of semi-trumpet-like separators 2 so that the flare 3 'is placed outward, and the outside of the separator 2 is provided. The vertical deflection coil 5 wound around the ferrite core 4 is attached thereto.

상기한 수평편향코일(3)의 플레어(3')가 위치된 개구부(6)에는 1쌍의 차폐판(7) (7')이 끼워진다.A pair of shield plates 7 and 7 'is fitted into the opening 6 in which the flare 3' of the horizontal deflection coil 3 is located.

이들 차폐판(7)(7')은 수평편향코일(3)의 플레어(3')를 차폐할 수 있는 정도의 길이를 가지며, 제 2 도에 나타낸 바와 같이 수평편향코일(3)의 플레어(3')를 감쌀 수 있도록 대략 단면이 ""자상으로 된 페라이트제이다.These shielding plates 7 and 7 'have a length enough to shield the flare 3' of the horizontal deflection coil 3, and as shown in FIG. 2, the flare of the horizontal deflection coil 3 3 ') roughly cross section " "It's a ferrite material.

상기한 바와 같이 구성되는 본 고안의 편향요크는 음극선관의 네크부에 장착되어 편향요크(1)에서 발생되어 스크린앞에 형성되는 불필요한 누설 방사자계를 차폐시키게 되는데, 이는 1쌍의 차폐판(7)(7')이 수평편향코일(3)의 플레어(3')를 감싸는 형태로 편향요크(1)의 개구부(6)측 선단에 부착되는 것이므로 수평편향코일(3)에서 발생되는 누설자계, 특히 플레어(3')를 통해 방사되는 자계를 차폐하여 비임의 편향에 불필요한 누설자계가 생기지 않게 해준다.The deflection yoke of the present invention configured as described above is mounted on the neck portion of the cathode ray tube to shield the unnecessary leakage radiation field generated in the deflection yoke (1) and formed in front of the screen, which is a pair of shield plates (7) Since the 7 'is attached to the tip of the opening 6 side of the deflection yoke 1 in a manner to surround the flare 3' of the horizontal deflection coil 3, the leakage magnetic field generated in the horizontal deflection coil 3, in particular, By shielding the magnetic field radiated through the flare 3 ', unnecessary leakage magnetic field is not generated in the beam deflection.

이상과 같이 본 고안의 편향요크는 간단한 구성의 차폐판을 편향요크의 선단에 부착 설치함으로써, 편향요크에서 생성되는 편향자계중 특히 수평편향 코일의 플레어에서 방사되어 음극선관의 스크린 앞에 불필요한 자계를 형성하는 누설방사자계를 그 발생부위에서 차폐하는 것이므로 인체에 유해한 자계의 누설을 방지하고, 상기 누설자계에 의한 화질의 열화를 개선시켜 주는 유용한 고안이다.As described above, the deflection yoke of the present invention is attached to the distal end of the deflection yoke by installing a shield plate having a simple configuration, and radiates from the flare of the deflection yoke, in particular the horizontal deflection coil, to form an unnecessary magnetic field before the screen of the cathode ray tube It is a useful design to prevent the leakage of the magnetic field harmful to the human body, and to improve the deterioration of the image quality by the leakage magnetic field because it shields the leakage radiation magnetic field at the generating portion.
