본 고안은 편향요크(Deflection Yoke)에 관한 것으로서, 더 상세하게는 쎄퍼레이터에 형성되는 밴드부의 구조를 개량한 편향요크에 관한 것이다.The present invention relates to a deflection yoke, and more particularly to a deflection yoke in which a structure of a band portion formed in a separator is improved.
일반적으로 편향요크는 음극선관의 네크부에 설치되어 전자총으로부터 주사되는 전자빔을 수평 편향코일에서 발생하는 바렐분포 자계와 수직편향코일에서 발생하는 핀쿠션자계를 이용하여 상하 혹은 좌우로 편향시켜줌으로써 양호한 퓨리티 및 콘버어젼스 특성을 지니는 화면을 재생토록 하는 역할을 한다.Generally, the deflection yoke is installed on the neck of the cathode ray tube to deflect the electron beam scanned from the electron gun up and down or left and right by using the barrel distribution magnetic field generated from the horizontal deflection coil and the pincushion magnetic field generated from the vertical deflection coil. It plays the role of playing the screen with the convergence characteristic.
이러한 편향요크의 종래구조가 제1도에 도시되어 있는바, 이는 절두원추형의 코일쎄퍼레이터(10)의 외주면에 페라이트(11)에 감긴 한쌍의 수직편향코일(12)이 설치되고, 상기 코일쎄퍼레이터(10)의 내주면에는 수평편향코일(도시되지않음)이 설치된다. 그리고 상기 코일쎄퍼레이터(10)의 선단부에는 자계보정수단인 크로스 아암(13)이 설치되고, 후단부에는 클램프(15)에 의해 음극선관의 네크부(도시되지 않음)에 고정설치되는 밴드부(14)가 형성된다. 이러한 밴드부(14)는 다수의 축방향 절결홈(14a)에 의해 분할된 다수의 돌출편(14b)으로 형성되어 직경이 감소될 수 있도록 되어 있다.The conventional structure of such a deflection yoke is shown in FIG. 1, which is provided with a pair of vertical deflection coils 12 wound around the ferrite 11 on the outer circumferential surface of the truncated cone coil separator 10, and the coil separator A horizontal deflection coil (not shown) is installed on the inner circumferential surface of the radar 10. A cross arm 13, which is a magnetic field correction means, is installed at the tip end of the coil separator 10, and a band part 14 fixed to the neck part (not shown) of the cathode ray tube by the clamp 15 at the rear end part. ) Is formed. This band portion 14 is formed of a plurality of protruding pieces 14b divided by a plurality of axial notched grooves 14a so that the diameter can be reduced.
이와 같은 구성된 종래 편향요크는 음극선관의 네크부에 코일 셰퍼레이터(10)의 밴드부(14)를 삽입하고 클램프(15)로 상기 밴드부(14)를 네크부에 반고정시킨 상태에서 좌우로 회전시키면서 전자빔의 편향상태를 조절한 다음 클램프(15)로 밴드부(14)를 네크부에 위치고정하게 된다. 그러나 종래의 편향요크는 밴드부(14)가 다수의 축방향 절결홈(14a)에 의해 분할된 다수의 돌출편(14b)으로 형성되어 있으므로, 편향상태를 조절하는 과정에서 상기 돌출편(14b)에 마찰력으로 인한 비틀림응력이 발생하게 되고 이 상태에서 클램프(15)에 의해 위치고정되게 된다. 따라서 차후 음극선관의 동작시 발생되는 열에 의해 상기 돌출편(14b)이 열팽창되면서 비틀림응력이 작용하는 돌출편(14b)에 원상태로 복원되려는 힘이 작용하게 됨에 따라 상기 코일 쎄퍼레이터(10)의 최초 고정위치가 변하게 되어 퓨리티 및 콘버어젼스 특성이 저하되는 문제점이 있었다. 또한 밴드부(14)가 다수의 돌출편(14b)으로 형성되어 있으므로, 구조적으로 그 강도가 약하여 클램핑력이나 운반시 외부의 충격으로 돌출편이 파손되는 문제점이 있었다.In the conventional deflection yoke configured as described above, the band portion 14 of the coil separator 10 is inserted into the neck portion of the cathode ray tube and the clamp portion 15 is rotated from side to side while semi-fixing the band portion 14 to the neck portion. After adjusting the deflection state of the electron beam, the band portion 14 is fixed to the neck portion by the clamp 15. However, in the conventional deflection yoke, since the band portion 14 is formed of a plurality of projection pieces 14b divided by a plurality of axial notched grooves 14a, the deflection yoke is provided on the projection pieces 14b in the process of adjusting the deflection state. Torsional stress due to the frictional force is generated and in this state is fixed by the clamp 15. Therefore, as the projecting piece 14b is thermally expanded by the heat generated during the operation of the cathode ray tube in the future, a force for restoring to the original state is applied to the projecting piece 14b to which the torsion stress acts. There is a problem in that the fixed position is changed and the purity and convergence characteristics are lowered. In addition, since the band portion 14 is formed of a plurality of protruding pieces 14b, the strength of the band 14 is structurally weak, so that the protruding pieces are damaged due to clamping force or external impact during transportation.
본 고안은 상술한 바와 같은 문제점을 감안하여 안출된 것으로서, 편향상태조절시 마찰력으로 인한 비틀림응력이 발생되지 않으며, 구조적으로 그 강도가 보강된 밴드부를 갖는 편향요크를 제공함에 그 목적이 있다.The present invention is conceived in view of the above problems, the torsional stress caused by the frictional force is not generated when adjusting the deflection state, and its purpose is to provide a deflection yoke having a structurally reinforced band portion.
상기 목적을 달성하기 위하여 본 고안은, 수직편향코일과 수평편향코일이 설치된 코일쎄퍼레이터와, 코일쎄퍼레이터에 연속되게 형성된 밴드부와, 상기 밴드부에 설치되어 코일쎄퍼레이터를 음극선관의 네크부에 위치고정시키는 클램프를 구비하여된 편향요크에 있어서, 상기 밴드부가 중심 축방향으로의 장공이 그 둘레에 다수형성된 원통형으로 된 점에 그 특징이 있다.In order to achieve the above object, the present invention provides a coil separator provided with a vertical deflection coil and a horizontal deflection coil, a band part continuously formed on the coil separator, and a coil part installed on the band part to locate the neck of the cathode ray tube. In a deflection yoke provided with a clamp for fixing, it is characterized in that the band portion has a cylindrical shape with a large number of long holes in the central axial direction.
이하 첨부된 도면을 참조하여 본 고안에 따른 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도에는 본 고안에 따른 편향요크가 도시되어 있는 바, 이는 종래와 마찬가지로 절두원추형의 코일쎄퍼레이트(1)의 외주면에 페라이트(2)에 감긴 한쌍의 수직 편향코일(3)이 설치되고, 상기 코일쎄퍼레이터(1)의 내주면에는 수평편향코일(도시되지 않음)이 설치된다. 그리고 상기 코일쎄퍼레이터(1)의 선단부에는 자계보정수단인 크로스아암(4)이 설치되고, 후단부에는 본 고안의 특징에 따라 클램프(6)에 의해 음극선관의 네크부(도시되지 않음)에 고정설치되며 그 축방향으로 장공(5a)이 다수 형성된 원통형 밴드부(5)가 형성된다.2 shows a deflection yoke according to the present invention, which is provided with a pair of vertical deflection coils 3 wound around the ferrite 2 on the outer circumferential surface of the truncated cone-shaped coil separator 1, as in the prior art. A horizontal deflection coil (not shown) is installed on the inner circumferential surface of the coil separator 1. A cross arm 4, which is a magnetic field correction means, is installed at the front end of the coil separator 1, and the rear end of the coil separator 1 is connected to the neck of a cathode ray tube (not shown) by a clamp 6 according to a feature of the present invention. The cylindrical band portion 5 is fixedly installed and has a plurality of long holes 5a formed therein.
이와 같이 구성된 본 고안에 따른 편향요크는 음극선관의 네크부에 코일쎄퍼레이터(1)의 밴드부(5)를 삽입하고 클램프(6)로 상기 밴드부(5)를 반고정시킨 상태에서 좌우로 회전시키면서 전자빔의 편향상태를 조절한 다음 클램프(6)로 밴드부(5)를 네크부에 위치고정하게 되는데, 이때 밴드부(5)가 그 중심 축방향으로 장공(5a)이 다수 형성된 원통형으로 형성되어 있으므로, 편향상태조절시 밴드부(5)에 마찰력으로 인한 비틀림응력이 발생되지 않아 종래와 같이 음극선관의 동작시 발생되는 열로 인한 코일쎄퍼레이터의 위치변동이 발생되지 않게 된다. 또한 밴드부(5)가 그 축방향으로 장공(5a)이 다수 형성된 원통형으로 형성되어 있으므로, 종래에 비해 그 구조적 강도가 강하여 클램핑력이나 운반시 발생되는 충격으로 인해 밴드부가 파손되는 것을 극소화 시킬 수 있게 된다.In the deflection yoke according to the present invention configured as described above, the band portion 5 of the coil separator 1 is inserted into the neck portion of the cathode ray tube and rotates from side to side in a state in which the band portion 5 is semi-fixed by the clamp 6. After adjusting the deflection state of the electron beam, the band portion 5 is fixed to the neck portion by the clamp 6, since the band portion 5 is formed in a cylindrical shape in which a plurality of long holes 5a are formed in the central axial direction thereof. When the deflection condition is adjusted, the torsional stress due to the frictional force is not generated in the band part 5, so that the positional change of the coil separator due to the heat generated during operation of the cathode ray tube does not occur as in the prior art. In addition, since the band portion 5 is formed in a cylindrical shape in which a plurality of long holes 5a are formed in the axial direction, its structural strength is stronger than that of the conventional one, so that the band portion can be minimized from damage due to the clamping force or the impact generated during transportation. do.
이상에서 설명한 바와 같이 본 고안은 밴드부가 그 축방향으로 장공이 다수 형성된 원통형으로 구성되어 있으므로 전자빔의 편향상태 조절시 밴드부에 마찰력으로 인한 비틀림응력이 발생되지 않아 코일쎄퍼레이터의 최초 고정위치가 변동되지 않게 되고, 종래에 비해 그 구조적 강도가 강하여 클램핑 또는 운반시 발생되는 밴드부의 파손을 극소화 시킬수 있게 된다.As described above, since the band part is formed in a cylindrical shape in which a plurality of long holes are formed in the axial direction thereof, the torsional stress due to the frictional force is not generated when the deflection state of the electron beam is adjusted so that the initial fixed position of the coil separator does not change. Compared with the related art, its structural strength is stronger than that of the related art, thereby minimizing damage to the band portion generated during clamping or transportation.
