이 고안은 편향요크에 관한 것으로서, 더욱 상세하게는 불요복사 방지용 코일이 감겨지는 한쌍의 고정부재가 편향요크의 페라이트 코어에 감겨진 수직편향코일 외측에 결합되어 설치되도록 한 편향요크의 불요복사 방지용 코일 고정장치에 관한 것이다.The present invention relates to a deflection yoke, and more specifically, a deflection yoke unnecessary radiation prevention coil in which a pair of fixing members to which an unnecessary radiation prevention coil is wound is installed to be coupled to an outer side of a vertical deflection coil wound on a ferrite core of the deflection yoke. It relates to a fixing device.
일반적으로, 편향요크는 TV수상기의 음극선관 또는 컴퓨터 모니터 등에 장착되는 것으로, 상기 편향요크의 내, 외측에 권선된 수평 및 수직편향코일로 톱니파 펄스가 인가되면 플레밍의 왼손법칙에 의하여 자계가 발생되므로 전자총에서 방사되는 전자빔을 편향시켜 화면상에 위치를 결정시키게 되는 것이다.In general, the deflection yoke is mounted on a cathode ray tube or a computer monitor of a TV receiver, and when a sawtooth pulse is applied to the horizontal and vertical deflection coils wound inside and outside the deflection yoke, a magnetic field is generated by Fleming's left hand law. The electron beam emitted from the electron gun is deflected to determine the position on the screen.
그런, 상기 편향요크의 수직 및 수평편향 코일에 의해 음극선관 밖으로 누설자계가 발생되는데 이 누설자계는 초저주파수(약, 10KHz∼300KHz)대로서 인체에 악영향을 끼칠 가능성이 있기때문에 상기 초저주파수가 음극선관 밖으로 누설되는 것을 장지하기 위해 불요복사 방지용 코일을 편향표크에 설치하여 반대방향의 자계를 발생시킴으로써 이를 방지하여 왔고, 초저주파수가 발생되는 양이 일정치를 초과할 수 없도록 규격으로 정하고있는 실정이다.The leakage magnetic field is generated out of the cathode ray tube by the vertical and horizontal deflection coils of the deflection yoke. The leakage magnetic field has an extremely low frequency (about 10 KHz to 300 KHz), which may adversely affect the human body. In order to prevent leakage from outside the pipe, an anti-radiation coil has been installed on the deflection mark to prevent the magnetic field in the opposite direction, and this has been prevented and the standard is set so that the amount of ultra low frequency cannot exceed a certain value. .
종래에, 상기한 바와같은 불요복사 방지용 코일을 펀향요크에 설치하기 위해서 제1도에 나타낸 바와같이, 편향요크(1)의 수직편향 코일(2)의 외주면을 따라 좌, 우 대칭으로 교차되게 불요복사 방지용 코일(3)을 감고, 상기 불요복사 방지용 코일(3)의 양끝단을 단자판(4)의 수평편향코일(도시하지 않음) 및 세트내의 장치와 접지된 접지편(4a)에 각각 연결시키며, 상기 불요복사 방지용 코일(3)의 교차부를 클램프(5)로 고정시킨다.Conventionally, as shown in FIG. 1, in order to install the unnecessary radiation preventing coil as described above in the funnel yoke, it is unnecessary to cross left and right symmetrically along the outer circumferential surface of the vertical deflection coil 2 of the deflection yoke 1. Winding the copy protection coil 3, and connecting both ends of the unnecessary radiation protection coil 3 to the horizontal deflection coil (not shown) of the terminal plate 4, the device in the set and the grounded ground piece 4a, respectively. The intersection of the unnecessary radiation prevention coil 3 is fixed with the clamp 5.
그리나, 상기와 같은 편향요크(1)는 크로스 토크(Cross Talk)를 조정하여 화면을 보정할 경우, 불요복사방지용 코일(3)이 편향요크(1)의 수직편향 코일(2) 외주면에 감겨져 고정되므로 불요복사 방지용 코일(3)의 회전이 불가능하여 일측으로 기울어지게 되고, 상기 불요복사 방지용 코일(3)이 기울어진 상태에 따라 크로스 토크값(dB)이 저하됨은 물론 크로스 토크값이 높은 경우에도 불요복사 방지용 코일(3)에서 발생되는 자계의 영향으로 화면의 직각도가 저하되어 화면이 불량하게 되는 문제점이 있었다.However, in the deflection yoke 1 as described above, when the screen is adjusted by adjusting the cross talk, the unnecessary radiation preventing coil 3 is wound around the outer peripheral surface of the vertical deflection coil 2 of the deflection yoke 1 and fixed. Therefore, it is impossible to rotate the unnecessary radiation prevention coil 3 and tilts to one side, and the cross torque value (dB) is lowered as the unnecessary radiation prevention coil 3 is inclined, and the crosstalk value is high. Due to the influence of the magnetic field generated by the unnecessary radiation prevention coil 3, there is a problem that the screen perpendicularity is lowered and the screen is poor.
이 고안은 상기와 같은 문제점을 해결하기 위한 것으로, 이 고안의 목적은, 편향요크의 페라이트 코어에 감겨진 수직편향 코일 외측에 불요복사 방지용 코일이 감겨지는 한쌍의 고정부재를 대향되도록 설치함으로써, 고정부재를 회전시켜 크로스 토크값을 조정시키므로 화면의 직각도를 보정할 수 있어 화션의 특성을 향상시킬수 있는 편향요크의 불요복사 방지용 코일 고정장치를 제공하는데 있다.The present invention is to solve the above problems, the object of the present invention, by fixing the pair of fixing member is wound to the outer side of the vertical deflection coil wound on the ferrite core of the deflection yoke, the fixing member is fixed, The present invention provides a coil fixing device for preventing undesired radiation of the deflection yoke, which can correct the squareness of the screen by adjusting the cross talk value by rotating the member.
상기와 같은 목적을 달성하기 위한 이 고안의 특징은, 음극선관에 장착된 편향요크에서 발생되는 누설자계를 감쇄하기 위한 불요복사 방지용 코일을 편향요크에 설치함에 있어서; 고정부재의 일측에는 검림돌기가 형성되며 타측에는 걸림편이 형성되고, 상기 고정부재의 한쌍이 결합되어 편향요크의 페라이트코어에 감겨진 수직편향 코일 외측에 설치되며, 이 고정부재의 외주면에 불요복사 방지용 코일이 감겨져 설치되는 편향요크의 불요복사 방지용 코일 고정장치에 있다.A feature of this 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 cathode ray tube in the deflection yoke; One side of the fixing member is formed with a blackening protrusion, the other side is formed with a hook piece, the pair of the fixing member is coupled to the outside of the vertical deflection coil wound on the ferrite core of the deflection yoke, to prevent unnecessary radiation on the outer peripheral surface of the fixing member It is in the coil fixing device to prevent unnecessary radiation of the deflection yoke in which the coil is wound.

A pair of fixing members 18 is provided outside the vertical deflection coil 16.
이때, 상기 고정부재(18) 일측에는 걸림돌기(19)가 형성되며 타측에 형성된 걸림편(20)과 상호 결합되어 고정부재(18)가 대향되도록 설치되고, 이 고정부재(18) 외주면의 상, 하측에 좌, 우로 대칭되게 불요복사 방지용코일(21)을 감는다.At this time, one side of the fixing member 18 is formed with a locking projection 19 is coupled to each other and the locking piece 20 formed on the other side is installed so that the fixing member 18 to face, the upper surface of the fixing member 18 Winding the anti-radiation coil 21 symmetrically to the left and right in the lower side.
그리고, 상기 불요복사 방지용 코일(21)의 양끝단을 단자판(12)의 수평편향 코일 및 세트내의 장치와 접지된 접지편(12a)에 각각 연결시키고, 상기 불요복사 방지용 코일(21)의 교차부를 클램프(22)로 고정시킨다.Then, both ends of the unnecessary radiation prevention coil 21 are connected to the horizontal deflection coil of the terminal plate 12 and the device in the set and the grounded piece 12a grounded, respectively, and the crossing portion of the unnecessary radiation prevention coil 21 is connected. Secure with clamp 22.
한편, 제3도의 (b)는 이 고안에 따른 고정부재의 다른 실시상태를 설명하기 위한 도면으로, 고정부재(18) 외주면 상, 하측에 좌, 우로 대칭되는 요홈(23)이 형성되고, 상기 고정부재(18)의 요홈(23)에 불요복사 방지용코일(21)이 감겨진다.On the other hand, Figure 3 (b) is a view for explaining another embodiment of the fixing member according to the present invention, on the outer peripheral surface of the fixing member 18, grooves symmetrically formed left and right are formed, The unnecessary radiation prevention coil 21 is wound around the groove 23 of the fixing member 18.
상술한 바와같이 이 고안은 크로스 토크를 조정하여 화면을 보정할 경우, 먼저 편향요크(11) 자체의 크로스토크값을 조정시키고, 상기 편향요크(11)의 수직편향 코일(16) 외주면에 설치된 고정부재(18)를 회전시키면서 불요복사 방지용 코일(21)의 설치위치를 변동시켜 크로스 토크값을 상승시키며, 상기 상기 불요복사 방지용코일(21)의 크로스 토크값이 상승되면서 화면의 직각도가 향상될 수 있는 것이다.As described above, when the screen is corrected by adjusting the crosstalk, the present invention first adjusts the crosstalk value of the deflection yoke 11 itself, and is fixed to the outer peripheral surface of the vertical deflection coil 16 of the deflection yoke 11. The crosstalk value is increased by changing the installation position of the unnecessary radiation preventing coil 21 while rotating the member 18, and the squareness of the screen is improved while the cross torque value of the unnecessary radiation preventing coil 21 is increased.
