본 고안은 불요복사 방지용 코일(canceller coil)이 설치된 편향요크에 관한 것으로서, 특히 편향요크의 수직 편향코일의 외주면의 상,하측에 좌, 우로 대칭되는 불요복사 방지용 코일을 권선시켜 클램프로 고정되게한 불요복사 방지용 코일에 관한 것이다.The present invention relates to a deflection yoke in which an unnecessary radiation prevention coil (canceller coil) is installed, and in particular, a coil of an anti-radiation prevention coil symmetrically symmetrically left and right on the outer circumferential surface of the vertical deflection coil of the deflection yoke is fixed to the clamp. It relates to a coil for preventing unnecessary radiation.
일반적으로 편향요크(1)는 제 1 도에 나타낸 바와같이 텔레비젼의 브라운관(CRT)(2) 또는 컴퓨터 모니터등에 장착되는 것으로, 상기 편향요크(1)의 내,외측에 권선된 수평 및 수직편향코일(3)로 톱니파 펄스가 인가되면 플레밍의 왼손법칙에 의하져 자계가 발생되므로 전자총에서 방사되는 전자빔을 편향시켜 화면상에 위치결정시키게 되는 것이다.Generally, the deflection yoke 1 is mounted on a CRT 2 or a computer monitor of a television as shown in FIG. 1, and the horizontal and vertical deflection coils wound inside and outside the deflection yoke 1 are shown in FIG. When the sawtooth pulse is applied to (3), the magnetic field is generated by Fleming's left-hand law, so the electron beam emitted from the electron gun is deflected and positioned on the screen.
그러나 브라운관 밖으로 편향요크의 수직 및 수평편향코일에 의해 누설자계가 발생되는데, 이 누설자계는 초저주파수(Very Low Freguency)(약 10KHz∼300KHz)대로서 인체에 악영향을 끼칠 가능성이 있기때문에 상기 초주파수(VLF)가 브라운관 밖으로 누설되는 것을 방지하기 위해 불요복사 방지용 코일(Canceller Coil)을 편향요크에 설치하여 역방향의 자계를 발생시키므로서 이를 방지하여 왔고, 초저주파수가 발생되는 양이 일정치를 초과할 수 없도록 규격으로 정하고 있는 실정이었다.However, leakage magnetic fields are generated by the vertical and horizontal deflection coils of the deflection yoke outside the CRT, which are very low frequency (approximately 10 KHz to 300 KHz), which may adversely affect the human body. In order to prevent (VLF) from leaking out of the CRT, an anti-irradiation coil (Canceller Coil) has been installed in the deflection yoke to generate the magnetic field in the reverse direction, and this has been prevented, and the amount of ultra low frequency generated exceeds a certain value. It was a situation that is determined by the standard so that.
따라서 편향요크에 불요복사 방지용 코일을 부착시키기 위해 종래에 여러가지 방법이 시도되었으나 불요복사 방지용 코일의 부착공간이 늘어나 제품의 콤팩트(compact)화에 바람직스럽지 못할뿐만 아니라, 조립작업이 용이하지 못하므로 조립성 및 생산성 향상에 저해되는 문제점이 있었다.Therefore, various methods have been conventionally attempted to attach the anti-radiation coil to the deflection yoke, but the mounting space of the anti-radiation coil is increased, which is not desirable for compacting the product, and the assembly work is not easy. There was a problem that hampered improvement in productivity and productivity.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로, 본 고안의 목적은, 편향요크의 수직편향코일의 외주면의 상,하측에 좌우로 대칭되는 불요복사 방지용 코일을 권선시켜 클램프로 고정시킬 수 있도록 하여 누설자계를 제거함과 동시에 제품조립용 용이하게 하고, 제품의 콤펙트화를 가능하도록 한 편향요크의 불요복사 방지용 코일을 제공하는 것에 있다.The present invention has been devised in view of the above problems, and an object of the present invention is to wind a coil for preventing radiation that is symmetrically left and right on the upper and lower sides of an outer circumferential surface of a vertical deflection coil of a deflection yoke so as to be fixed by a clamp. The present invention provides a coil for preventing undesired radiation of a deflection yoke, which facilitates assembly of a product and enables compaction of a product while removing a leakage magnetic field.
상기와 같은 목적을 달성기 위한 본 고안의 특징은, 브라운관에 장착된 편향요크에서 발생되는 누설자계를 감쇄하기 위한 불요복사 방지용 코일을 편향요크에 설치함에 있어서, 편향요크의 수직편향코일 외주면의 상,하측에 좌,우로 대칭되는 불요복사 방지용 코일을 권선시켜 단자판의 접지편에 접지시키고, 상기 불요복사 방지용 코일의 교차부를 클램프로 고정시킨 것이다.A feature of the present invention for achieving the above object is, 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 image of the outer surface of the vertical deflection coil of the deflection yoke The left and right symmetrical anti-radiation coils are wound on the lower side and grounded to the ground piece of the terminal plate, and the intersection of the unnecessary radiation prevention coils is clamped.
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 도에 나타낸 바와같이, 편향요크(1)의 수직편향코일(3)의 외주면을 따라 좌, 우 대칭으로 교차되게 불요복사 방지용 코일(4)을 권선하고, 상기 불요복사 방지용 코일(4)의 양끝단을 단자판(5)의 수평편향코일 및 세트내의 장치와 접지된 접지편(6)에 각각 접지시키며, 상기 불요복사 방지용 코일(4)의 교차부를 클램프(7)로 구성시킨 구성으로 되어있다.The present invention, as shown in Figure 2, winding the unnecessary radiation prevention coil (4) to cross left and right symmetry along the outer circumferential surface of the vertical deflection coil (3) of the deflection yoke (1), the unnecessary radiation prevention coil Both ends of (4) are grounded to the horizontal deflection coil of the terminal plate (5) and the device in the set and the grounded ground piece (6), respectively, and the intersection of the unnecessary radiation preventing coil (4) is constituted by the clamp (7). It is composed.
이때, 상기 불요복사 방지용 코일(4)은 여러가닥의 코일이 수지로 피복된 것이다.At this time, the unnecessary radiation preventing coil 4 is coated with a resin of several strands.
이와같은 구성의 본 고안은 편향요크(1)의 수직 및 수평편향코일에 의해 인체에 해로운 누설자계가 발생되면, 상기 수평편향코일과 단자편(5)의 접지편(6)에서 서로 연결된 불요복사 방지용 코일(4)에 전류가 흘러 상기 누설자계와는 역방향의 자계가 발생된다.The present invention of such a configuration is that when the leakage magnetic field harmful to the human body is generated by the vertical and horizontal deflection coils of the deflection yoke (1), unnecessary radiation connected to each other at the ground piece (6) of the horizontal deflection coil and the terminal piece (5) The current flows through the prevention coil 4 to generate a magnetic field in the opposite direction to the leakage magnetic field.
따라서 상기 불요복사 방지용 코일(4)의 역자계에 의해 누설자계가 감쇄되므로 규격으로 정하고 있는 기준치를 맞출수 있게 된다.Therefore, the leakage magnetic field is attenuated by the reverse magnetic field of the unnecessary radiation preventing coil 4, so that the reference value specified in the standard can be met.
이상에서와 같이 본 고안은 누설자계가 감쇄됨과 동시에 불요복사 방지용 코일의 설치구조가 간편해짐에 따라 제품의 조립 및 생산성을 향상시키고 제품을 콤팩트화할 수 있는 것이다.As described above, according to the present invention, as the leakage magnetic field is attenuated and the installation structure of the unnecessary radiation prevention coil is simplified, the assembly and productivity of the product can be improved and the product can be made compact.
