본 고안은 편향요크에 관한 것으로서, 더욱 상세하게는 음극선관의 스크린 앞에 형성되는 누설 방사자계를 차폐시키도록 한 편향요크에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to a deflection yoke for shielding a leakage radiating field formed in front of a screen of a cathode ray tube.
일반적으로 편향요크는 반나팔체상을 갖는 1쌍의 세페레이터의 내측에 수평 편향코일이 위치되고, 그 외측에는 페라이트 코어에 권선된 수직 편향코일이 배치되어 이루어지는 것으로서, 음극선관의 네크부에 장착된다.In general, the deflection yoke is a horizontal deflection coil located 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 수평주사용 톱니파 전류를 흘리게 되면 음극에서 주사되는 전자비임을 편향요크에서 발생되는 편향자계에 의해 상하 및 좌우로 편향되어 스크린상에 라스터를 그리게 된다.When a vertical and horizontal injection 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 수직편향코일에서 발생되는 수직편향자계가 형성되는데, 이중에서 수평편향자계는 스크린의 앞쪽에 인체에도 유익하지 않고 비임의 편향에도 불필요한 방사자계를 형성시키게 된다.By the way, the deflection magnetic field generated in the deflection yoke is formed with a horizontal deflection magnetic field formed in the horizontal deflection coil and a vertical deflection magnetic field generated in the vertical deflection coil, of which the horizontal deflection magnetic field is not beneficial to the human body in front of the screen. It also forms an unnecessary radiation field even in the case of deflection.
종래에, 상기한 바와 같은 스크린의 앞쪽에 형성되는 불필요한 누설방지자계를 감소시키기 위하여 편향요크(D)의 개구부측에 사각형상의 페라이트코어(F)에 코일(C)을 권선하여 제3도에 나타낸 바와 같이 개구부측에 부착시키고 있으나, 이는 편향요크(D)의 중앙선상에 위치되므로 인하여 스크린앞의 좌, 우에 형성되는 누설자계등의 전반적인 누설방사자계는 상쇄시킬수 없다.Conventionally, the coil C is wound around a rectangular ferrite core F on the opening side of the deflection yoke D in order to reduce the unnecessary leakage preventing magnetic field formed in front of the screen as shown in FIG. As it is attached to the opening side, but because it is located on the center line of the deflection yoke (D), the overall leakage radiation field, such as the leakage magnetic field formed on the left and right in front of the screen cannot be canceled out.
또, 제4도에 나타낸 바와 같이 음극선관(T)의 네크부에 장착된 편향요크(D)의 전면부에 페라이트 링(R)을 설치하여 누설자계를 감소시키도록 하고 있으나, 이는 수동적인 것으로 수평주파수에 따라서 저주파수일때는 고투자율을, 고주파수일때는 저투자율의 링을 사용해야 하는등의 문제점이 있다.In addition, as shown in FIG. 4, a ferrite ring R is provided on the front surface of the deflection yoke D mounted on the neck of the cathode ray tube T to reduce the leakage magnetic field. According to the horizontal frequency, there is a problem of using a high permeability at low frequency and a low permeability ring at high frequency.
본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 음극선관의 스크린 앞에 형성되는 불필요한 누설 방사자계를 차폐시키도록 한 편향요크를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to provide a deflection yoke to shield 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; 개구부측 선단에 내측으로 절곡 형성된 1쌍의 차폐판을 갖는 페라이트 시이트가 부착 설치되는 편향요크를 제공한다.In order to achieve the above object, the present invention is a deflection yoke mounted on the neck portion of the cathode ray tube deflecting the electron beam is scanned from the cathode; Provided is a deflection yoke to which a ferrite sheet having a pair of shield plates bent inwardly at an opening side end is attached.
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.
제1도는 본 고안의 편향요크를 나타내는 일부 분해 사시도로서, 부호(1)은 편향요크를 나타낸다.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 코일세퍼레이터(2)의 내측에 별도로 권선된 1쌍의 수평편향코일(3)이 부착설치되고, 그 외측에는 1쌍의 수직편향코일(4)이 페라이트코어(5)에 권선되어 있다.The deflection yoke 1 has a pair of horizontal deflection coils 3 wound separately on the inner side of the coil separator 2, and a pair of vertical deflection coils 4 is disposed on the outer side of the coil separator 2. ) Is wound.
상기한 코일 세퍼레이터(2)의 개구부(6)측 선단에는 내측으로 절곡 형성된 1쌍의 차폐판(7)(7')을 일체로 보유한 페라이트 시이트(8)가 제2도에 나타낸 바와 같이 결합되어진다.At the tip of the opening 6 side of the coil separator 2, a ferrite sheet 8 integrally holding a pair of shield plates 7 and 7 'bent inward is coupled as shown in FIG. Lose.
상기한 차폐판(7)(7')은 수평편향코일(3)에서 비임의 편향에 불필요한 자계를 형성시키는 부분인 라운드부(3')를 차폐하는 길이면 충분하다.The shielding plates 7 and 7 'are sufficient to shield the round portion 3', which is a part of the horizontal deflection coil 3, which forms an unnecessary magnetic field for beam deflection.
상기한 바와 같이 구성되는 본 고안의 편향요크는 음극선관의 네크부에 장착되어 편향요크(1)에서 발생되어 스크린앞에 형성되는 불필요한 누설방사자계를 차폐시키게 되는데. 이는 페라이트 시이트(8)를 편향요크(1)의 개구부(6)측 선단에 부착 시키므로써, 특히 수평편향코일(3)의 라운드부(3')에서 발생되는 비임의 편향에 불필요한 누설 방사자계를 차폐판(7)(7')이 차폐시키게 된다.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. This causes the ferrite sheet 8 to be attached to the tip of the opening 6 side of the deflection yoke 1, thereby avoiding a leakage radiation field that is unnecessary for deflection of the beam generated in the round portion 3 'of the horizontal deflection coil 3. The shield plates 7 and 7 'will shield.
이상과 같은 본 고안의 편향요크는 간단한 구성의 페라이트 시이트를 편향요크의 선단부에 부착 설치하므로써, 편향요크에서 생성되는 편향자계중 음극선관의 스크린 앞에 형성되는 불필요한 누설방사자계를 차폐하여 자계의 누설을 방지하고, 인체에도 영향을 미치지 않는 유용한 고안이다.As described above, the deflection yoke of the present invention attaches a ferrite sheet having a simple configuration to the distal end of the deflection yoke, thereby shielding the unnecessary leakage radiation field formed in front of the screen of the cathode ray tube of the deflection yoke generated by the deflection yoke to prevent leakage of the magnetic field. It is a useful design that prevents and does not affect the human body.
