본 고안은 편향요크에 관한 것으로서, 특히 편향요크의 코일세퍼레이터에 불요복사 방지용 코일(canceller coil)을 일정각도로 유지시켜 설치할 수 있게한 불요복사 방지용 코일이 설치된 편향요크에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to a deflection yoke provided with an undesired radiation prevention coil installed in a coil separator of the deflection yoke to maintain and install an unnecessary radiation coil.
일반적으로, 편향요크(1)는 제 1 도에 도시된 바와같이 텔레비젼의 브라운관(CRT)(2) 또는 컴퓨터의 모니터 등에 장착되는 것으로, 상기 편향요크(1)의 내, 외측에 권선된 수평 수직편향코일(3)로 톱니파펄스가 인가되면 플레밍의 왼손법칙에 의하여 자계가 발생되어 전자총에서 방사되는 전자빔을 편향시켜 화면상에 위치결정시키게 된다.In general, the deflection yoke 1 is mounted on a CRT 2 of a television or a monitor of a computer as shown in FIG. 1, and the horizontal and vertical windings of the deflection yoke 1 are carried out inside and outside. When a sawtooth pulse is applied to the deflection coil 3, a magnetic field is generated by Fleming's left-hand law to deflect the electron beam emitted from the electron gun and position it on the screen.
그러나 브라운관 밖으로 편향요크의 수직 및 수평편향코일에 의해 발생되는 초저주파수(Very Low frequency)(약 10KHz∼300KHz)의 누설자계가 누출되어 인체에 악 영향을 끼칠 가능성이 있다.However, leakage of magnetic fields of very low frequency (approximately 10 KHz to 300 KHz) generated by vertical and horizontal deflection coils of the deflection yoke out of the CRT may adversely affect the human body.
따라서, 상기 초저주파수(VLF)가 브라운관밖으로 누설되는 것을 방지하기 위해 불요복사 방지용 코일(Canceller Coil)을 편향요크에 설치하여, 브라운관에서 발생되는 누설자계중 편향요크에서 방사되는 편향자계의 누설자계를 브라운관의 중앙축 전면의 30㎝와 50㎝등에서 현 레벨(Level)의 1/5∼1/10정도로 낮추어 줄 필요가 있으며 초저주파수가 발생되는 양이 일정치를 초과할 수 없도록 규격으로 정하고 있는 실정이었다.Therefore, in order to prevent the ultra low frequency (VLF) from leaking out of the CRT, an unnecessary radiation prevention coil (Canceller Coil) is installed in the deflection yoke, so that the leakage magnetic field of the deflection magnetic field radiated from the deflection yoke is generated. It is necessary to lower the current level to about 1/5 to 1/10 of the current level from 30cm and 50cm in front of the central axis of the CRT, and the standard is set so that the amount of ultra low frequency cannot exceed a certain value. It was.
그러므로, 종래에도 편향요크에 불요복사 방지용 코일을 설치하기 위해 여러가지 방법이 시도되었으나, 불요복사 방지용 코일의 설치 작업시 위치설정이 어렵고, 설치공정이 용이하지 못하여 작업성 및 생산성이 저하되는 문제점이 발생하였다.Therefore, in the past, various methods have been attempted to install an unnecessary radiation preventing coil in a deflection yoke. However, when the installation of the unnecessary radiation preventing coil is performed, it is difficult to set the position, and the installation process is not easy. It was.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로, 본 고안의 목적은, 편향요크의 코일세퍼레이터에 불요복사 방지용 코일을 일정각도 기울도록 설치하여 편향요크에서 발생되는 누설자계를 감쇄시키며, 불요복사 방지용 코일의 설치작업시 설치위치가 용이하게 설정되고, 설치공정이 간단하여 작업성 및 생산성이 향상된 불요복사 방지용 코일이 설치된 편향요크를 제공한 것이다.The present invention has been devised in view of the above problems, and an object of the present invention is to install a coil for preventing radiation in the deflection yoke so as to incline a predetermined angle to attenuate the leakage magnetic field generated by the deflection yoke, and thus unnecessary radiation. The installation position is easily set at the time of installation of the prevention coil, and the installation process is simple, thereby providing a deflection yoke having an unnecessary radiation prevention coil having improved workability and productivity.
상기와 같은 목적을 달성하기 위한 본 고안의 특징은, 브라운관에 장착된 편향요크에서 발생되는 누설자계를 감쇄하기 위한 불요복사 방지용 코일을 편향요크에 설치함에 있어서, 편향요크의 코일세퍼레이터 하단부에 형성된 마그네트홀더에 불요복사 방지용 코일을 권선시킨 코일권선 부재가 일정각도로 기울어지도록 고정되게 설치한 것이다.A feature of the present invention for achieving the above object, in the installation of the undesired radiation prevention coil to attenuate the leakage magnetic field generated in the deflection yoke mounted on the CRT on the deflection yoke, the magnet formed in the coil separator lower end of the deflection yoke The coil winding member in which the coil for preventing unnecessary radiation is wound in the holder is installed to be inclined at an angle.
이하, 본 고안의 실시예를 첨부한 도면에 따라 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 제 2 도 및 제 3 도에 나타낸 바와같이, 한쌍의 수평편향코일과 수직편향코일(3)로 구성되는 편향요크(1)의 코일세퍼레이터(4) 하단부에 형성된 마그네트홀더(5)에 불요복사 방지용 코일(6)을 권선시킨 코일권선부재(7)가 45°∼50°로 일정각도(α) 기울어 고정되도록 끼워 설치되고, 상기 불요복사 방지용 코일(6) 일끝단은 수평편향코일에 접지되고 타단은 세트내의 장치와 접지된다.The present invention has a magnet holder 5 formed at the lower end of the coil separator 4 of the deflection yoke 1 composed of a pair of horizontal deflection coils and a vertical deflection coil 3, as shown in Figs. The coil winding member 7 wound around the coil 6 for preventing radiation is fitted to be fixed at an angle α to 45 ° to 50 °, and one end of the coil 6 for preventing radiation is disposed on a horizontal deflection coil. It is grounded and the other end is grounded with the devices in the set.
한편, 상기 코일권선부재(7)는 제 4 도에 나타낸 바와같이 코일세퍼레이터(4)의 마그네트홀더(5) 양측벽에 끼워져 고정되는 삽입공간(8)이 형성되고, "H"형 지지편(9), (9a)의 테두리를 따라 불요복사 방지용 코일(6)이 권선되는 요홈(10)을 형성한다.On the other hand, as shown in FIG. 4, the coil winding member 7 is provided with an insertion space 8 which is fitted to both side walls of the magnet holder 5 of the coil separator 4 and is fixed thereto. 9), to form a groove 10 to which the coil for preventing radiation 6 is wound along the edge of (9a).
