이 고안은 편향요크에 관한 것으로써, 더욱 상세하게는 음극선관(CRT)에서 발생되는 누설자계를 방지하는 누설자계 방지용 코일이 고정부재에 감겨져 코일세퍼레이터에 설치됨으로써 작업성이 향상됨과 동시에 제품의 소형화가 이루어지도록 한 편향요크의 누설자계 코일 고정장치에 관한 것이다.The present invention relates to a deflection yoke. More specifically, a leakage magnetic field preventing coil that prevents leakage magnetic fields generated in a cathode ray tube (CRT) is wound around a fixing member and installed in a coil separator, thereby improving workability and miniaturizing the product. It relates to a leakage magnetic field coil fixing device of the deflection yoke to be made.

일반적으로 T.V수상기 또는 모니터등의 음극선관에 사용되는 편향요크는, 코일세퍼레이터의 내,외측에 감겨진 수평 및 수직 편향코일에 톱니파 펄스를 인가시키게 되면 플레밍의 왼손법칙에 의하여 자계가 발생되므로 전자총에서 방사되는 R(적색), G(녹색), B(청색)의 전자빔을 편향시켜 화면상에 주사위치를 결정하게 되는 것이다.In general, deflection yokes used in cathode ray tubes such as TV receivers or monitors have a magnetic field generated by Fleming's left-handed law when a sawtooth pulse is applied to the horizontal and vertical deflection coils wound inside and outside the coil separator. Diffuses on the screen are determined by deflecting the emitted R (red), G (green), and B (blue) electron beams.

그러나, 상기 편향요크의 수평 및 수직 편향코일에 의해 음극선관 밖으로 누설자계가 발생되는데 이 누설자계는 초저주파수(약 10㎑∼300㎑)대로서 인체에 악영향을 끼칠 가능성이 높기 때문에, 편향요크에 누설자계와 반대방향의 자계를 발행시키는 누설자계 방지용 코일을 설치하여 상호 감쇠시킴으로써 초저주파수대의 누설자계가 음극선관 밖으로 누설되는 것을 방지하여 왔고, 상기 초저주파수가 발생되는 양이 일정치를 초과할 수 없도록 규격, 예를 들면, 국제적인 안전규격에서는 음극선관에서 5m떨어진 위치에서 0.5밀리렌트겐매시이하로 정하고 있는 실정이다.However, the leakage magnetic field is generated out of the cathode ray tube by the horizontal and vertical deflection coils of the deflection yoke. Since the leakage magnetic field is very low frequency (about 10 kHz to 300 kHz), it is highly likely to adversely affect the human body. By installing a leakage magnetic field preventing coil that generates a magnetic field opposite to the leakage magnetic field and mutually attenuating, the leakage magnetic field of the ultra low frequency band has been prevented from leaking out of the cathode ray tube, and the amount of the ultra low frequency generated may exceed a certain value. The standard, for example, the international safety standard, is defined as less than 0.5 millent genmash at a position 5 m away from the cathode ray tube.

종래에는, 상기와 같은 누설자계를 방지하기 위하여 제1a, b도에 나타낸 바와 같이, 누설자계 방지용 코일(1)이 감겨져 안내되는 다수개의 걸림돌기( 2)가 고정부재(3)의 소정부위에 형성되고, 상기 고정부재(3)의 중앙에는 누설자계방지용 코일( 1)의 감김상태를 조정할 수 잇는 조절부재(4)가 장착되며, 이 고정부재(3)의 일측에는 결합편(5)이 형성되어 코일세퍼레이터(6)의 스크린부(7) 외주면에 형성된 결합편(8)에 끼워 맞춤됨으로써 편형요크(9)에 소정각도로 기울어져 설치되었다.Conventionally, in order to prevent the leakage magnetic field as described above, as shown in FIGS. 1A and 1B, a plurality of locking projections 2, on which the leakage magnetic field preventing coil 1 is wound and guided, are placed on a predetermined portion of the fixing member 3. It is formed, the center of the fixing member (3) is equipped with a control member (4) for adjusting the winding state of the leakage magnetic field prevention coil (1), the coupling piece (5) on one side of the fixing member (3) It was formed and fitted to the engaging piece 8 formed on the outer circumferential surface of the screen portion 7 of the coil separator 6 so as to be inclined at a predetermined angle to the knitted yoke 9.

그러나, 상기와 같은 누설자계방지용 코일의 고정장치는, 대형광각용 음극선관의 편향요크에 사용할 수 있으나 소형의 편향요크에는 부적합한 것으로써, 편향요크(9)의 스크린부(7)에 고정부재(3)가 소정각도로 기울어져 설치되므로 설치공간을 많이 차지하여 T.V수상기 또는 모니터내에 장착되는 다른 부품들과 접촉되고, 고정부재(3)를 편향요크(9)에 설치할 때 발생하는 오차로 인하여 누설자계를 감쇄시킬 수 있는 효율이 저하됨과 동시에 누설자계방지용 코일(1)을 조정할 수 있는 조절부재(4)가 밖으로 나가기 때문에 조정작업이 불편하며, 누설자계 방지용 코일( 1)이 고정부재(3)의 걸림돌기(2)에 감겨진 후 외측으로 빠져나가 흘러내리게 되므로 작업성이 저하되는 문제점이 있었다.However, the fixing device for the leakage magnetic field preventing coil as described above may be used for the deflection yoke of the large-angle wide-angle cathode ray tube, but is unsuitable for the small deflection yoke, so that the fixing member (for the screen portion 7 of the deflection yoke 9) 3) is installed at an inclined angle so that it takes up a lot of installation space and is in contact with other components mounted in the TV receiver or monitor, and leaks due to an error occurring when the fixing member 3 is installed in the deflection yoke 9. Since the efficiency to attenuate the magnetic field is reduced and the adjusting member 4 for adjusting the leakage magnetic field preventing coil 1 goes out, adjustment work is inconvenient, and the leakage magnetic field preventing coil 1 is fixed to the fixing member 3. After being wound on the locking projection 2, the product was dropped outward and flowed down, which led to a problem of deterioration of workability.

이 고안은 상기와 같은 문제점을 해결하기 위한 것으로서 이 고안의 목적은, 음극선관에서 발생되는 누설자계를 방지하는 누설자계방지용 코일이 고정부재의 감김홈에 감겨져 코일세퍼레이터의 스크린부 상면에 형성되는 고정편에 수직상태로 설치됨으로서, 고정부재에 감겨지는 누설자계방지용 코일이 풀어지면서 외측으로 빠져나갈 염려가 없을 뿐만 아니라, 상기 누설자계방지용 코일이 감겨지는 시작선과 끝선을 용이하게 배선할 수 있어 작업성이 향상되고, 고정부재가 코일세퍼레이터의 스크린부 상면에 수직상태로 설치되므로 설치공간을 작게 차지하여 제품의 소형화 제작이 가능해짐과 동시에 스크린부에 마그네트등을 장착할 수 있어 화면상에 발생되는 디스토션(Distortion)등을 미세조정할 수 있는 편향요크의 누설자계방지용 코일의 고정장치를 제공하는 데 있다.The object of the present invention is to solve the above problems, and the object of the present invention is to prevent the leakage magnetic field generated in the cathode ray tube coil is wound around the winding of the fixing member is formed on the upper surface of the screen of the coil separator fixed Since it is installed vertically on the side, there is no fear that the leakage magnetic field coil wound around the fixing member is released, and it is possible to easily wire the start line and the end line on which the leakage magnetic field coil is wound. It is improved, and the fixing member is installed vertically on the upper surface of the screen of the coil separator, so it takes up a small installation space, making the product compact, and at the same time, it is possible to mount magnets on the screen, so that distortion occurs on the screen. Fixed coil for preventing leakage magnetic field of deflection yoke that can finely adjust distortion To provide a device.

상기와 같은 목적을 달성하기 위한 이 고안의 특징은, 음극선관에서 발생되는 누설자계가 감쇠되도록 코일세퍼레이터의 스크린부에 누설자계방지용 코일이 설치되는 편향요크에 있어서, 상기 누설자계 방지용 코일의 시작선과 끝선이 각각 감겨지는 감김봉이 지지편 일측에 형성되며, 상기 지지편의 테두리를 따라 누설자계 방지용 코일이 감겨지는 감기홈이 형성되고 그 하부에 결합편이 형성되는 고정부재와, 상기 고정부재의 결합편이 결합되어 수직상태로 설치되도록 하는 고정편이 스크린부 상면에 형성되는 코일세퍼레이터로 이루어지는 편향요크의 누설자계 방지용 코일의 고정장치에 있다.In order to achieve the above object, a feature of the present invention is a deflection yoke in which a leakage magnetic field preventing coil is installed in a screen portion of a coil separator so that a leakage magnetic field generated in a cathode ray tube is attenuated. Winding rods each of which is wound around the end line is formed on one side of the support piece, the fixing member is formed with a winding groove for winding the leakage magnetic field prevention coil is wound along the edge of the support piece and the coupling piece is formed at the bottom thereof, The fixing piece to be coupled to be installed in a vertical state is in the fixing device of the coil for preventing the leakage magnetic field of the deflection yoke consisting of a coil separator formed on the upper surface of the screen portion.

이하, 이 고안에 따른 편향요크의 누설자계방지용 코일의 고정장치를 첨부된 도면에 의하여 상세히 설명한다.Hereinafter, the fixing device of the leakage magnetic field prevention coil of the deflection yoke according to the present invention will be described in detail with the accompanying drawings.

제2도 및 제3a, b도는 이 고안에 따른 편향요크의 누설자계방지용 코일의 고정장치를 설명하기 위해 실시예를 나타낸 도면으로서, 먼저 편향요크(11)는 네크부( 12)와 스크린부(13)로 이루어지는 코일세퍼레이터(14)의 내측에 수평편향코일(도시하지 않음)이 감겨지고, 외측으로는 수직편향코일(15)이 감겨지는 페라이트 코어(16)가 코어클램프(17)에 의해 조립되며, 상기 코일세퍼레이터(14)의 스크린부(13)의 상면에는 공간부(18)을 갖도록 고정편(19a)(19b)을 각각 형성시킨다.2 and 3a, b is a view showing an embodiment for explaining the fixing device of the leakage magnetic field prevention coil of the deflection yoke according to the present invention, first, the deflection yoke 11 is the neck portion 12 and the screen portion ( A core deflection core 16 is assembled with a ferrite core 16 on which a horizontal deflection coil (not shown) is wound on the inner side of the coil separator 14, which is formed of 13, and a vertical deflection coil 15 is wound on the outer side. Fixing pieces 19a and 19b are formed on the upper surface of the screen portion 13 of the coil separator 14 so as to have a space 18.

또한, 누설자계방지용 코일(20)의 시작선과 끝선이 감겨지는 감김봉(21a) (21b)이 고정부재(22)의 지지편(23) 일측에 각각 형성되고 , 상기 고정부재(22)의 지지편(23) 중앙부에는 공간부(24)가 형성되며 그 테두리를 따라 누설자계방지용 코일(20)이 안내되어 감겨지는 감기홈(25)이 형성되고, 이 지지편(23)의 하부에는 결합편(26)이 양측에 형성되어 코일세퍼레이터(14)의 스크린부(13)상면에 형성되는 고정편(19a)(19b)의 공간부(18)에 결합된다.In addition, winding rods 21a and 21b on which the start line and the end line of the leakage magnetic field preventing coil 20 are wound are formed on one side of the support piece 23 of the fixing member 22, respectively, to support the fixing member 22. A space portion 24 is formed at the center of the piece 23, and a winding groove 25 is formed to guide and wind the leakage magnetic field preventing coil 20 along the edge thereof, and a coupling piece is formed below the support piece 23. (26) are formed on both sides and are coupled to the space portion 18 of the fixing pieces 19a and 19b formed on the upper surface of the screen portion 13 of the coil separator 14.

상술한 바와 같은 이 고안은 누설자계방지용 코일(20)의 시작선과 끝선을 구분하여 고정부재(22)의 감김봉(21a)(21b)에 감을 수 있어 수직편향코일과 용이하게 배선시켜 연결시킬 수 있으며, 상기 누설자계방지용 코일(20)의 풀어짐이 방지되므로 지지편(23)의 테두리를 따라 형성된 감김홈(25)에 감겨지는 누설자계방지용 코일(20)이 외측으로 빠져나갈 염려가 없게 되고, 상기 지지편(23)의 공간부(24)는 재료의 손실을 방지하기 위해 형성된다.This design as described above can be wound on the winding rods 21a and 21b of the fixing member 22 by dividing the start line and the end line of the leakage magnetic field preventing coil 20 so that the vertical deflection coil can be easily wired and connected. In addition, since the release of the leakage magnetic field preventing coil 20 is prevented, there is no fear that the leakage magnetic field preventing coil 20 wound around the winding groove 25 formed along the edge of the support piece 23 may escape to the outside. The space portion 24 of the support piece 23 is formed to prevent the loss of material.

또한, 고정부재(22)의 결합편(26)이 코일세퍼레이터(14)의 스크린부(13) 상면에 형성된 고정편(19a)(19b)의 공간부(18)에 결합되어 수직상태로 설치됨으로서 설치공간을 작게차지하여 제품의 소형화 제작이 가능해지고, 상기 코일세퍼레이터(14)의 스크린부(13) 외주면에 마그네트(도시하지 않음)등을 장착할 수 있는 여유가 생기므로 화면상에 발생되는 디스토션등을 미세 조정할 수 있게 된다.In addition, the coupling piece 26 of the fixing member 22 is coupled to the space portion 18 of the fixing pieces 19a and 19b formed on the upper surface of the screen portion 13 of the coil separator 14 so as to be installed in a vertical state. Distortion generated on the screen can be made possible by miniaturizing the product by minimizing the installation space, and there is room to mount a magnet (not shown) on the outer circumferential surface of the screen unit 13 of the coil separator 14. Etc., it becomes possible to fine tune.

그리고, T.V수상기 또는 모니터등의 음극선관에 편향요크(11)를 장착한 후, 상기 편향요크(11)의 수평 및 수직 편향코일(15)에 톱니파 펄스를 인가시키게 되면 자계를 형성하여 전자층에서 방사되는 R.G.B.의 전자빔을 주사시켜 화면상에 주사위치를 결정하게 되고, 상기 수평 및 수직편향코일(15)에 의해 음극선관 밖으로 누설자계가 발생하게 되면, 고정부재(22)에 감겨진 누설자계방지용 코일(20)에서 형성되는 반대 자계로 인하여 누설자계를 감쇠시키게 됨으로써 인체에 해로운 누설자계는 음극선관 밖으로 발생되지 않게 된다.When the deflection yoke 11 is mounted on a cathode ray tube such as a TV receiver or a monitor, a sawtooth pulse is applied to the horizontal and vertical deflection coils 15 of the deflection yoke 11 to form a magnetic field in the electronic layer. When the electron beam of the emitted RGB is scanned to determine the dice on the screen, when the leakage magnetic field is generated out of the cathode ray tube by the horizontal and vertical deflection coil 15, for preventing the leakage magnetic field wound on the fixing member 22 Since the leakage magnetic field is attenuated by the opposite magnetic field formed in the coil 20, the leakage magnetic field harmful to the human body is not generated outside the cathode ray tube.

이상에서와 같이 이 고안은 음극선관에서 발생되는 누설자계를 감쇠시키는 누설자계방지용코일이 고정부재에 감겨져 코일세퍼레이터의 스크린부 상면에 수직상태로 설치됨으로써, 누설자계방지용 코일의 풀어짐이 방지되면서 배선이 용이해져 작업성이 향상됨과 동시에 설치공간을 작게 차지하여 제품의 소형화 제작이 가능해지는 유용한 고안인 것이다.As described above, this design prevents the leakage magnetic field coil from attenuating the leakage magnetic field generated by the cathode ray tube, which is wound around the fixing member and installed vertically on the upper surface of the screen of the coil separator. It is easy to improve the workability and at the same time occupy a small installation space is a useful design that makes it possible to miniaturize the product.
