Description
본 고안은 편향요크의 페라이트코어에 관한 것으로서, 더욱 상세하게는 페라이트코어의 일부에 핀자계를 배럴화할수 있는 보정수단을 형성함으로써, 대형화면의 특성이 향상되는 편향요크의 페라이트코어에 관한 것이다.The present invention relates to a ferrite core of a deflection yoke, and more particularly, to a ferrite core of a deflection yoke, by forming a correction means capable of barrelizing a pin magnetic field on a part of the ferrite core, thereby improving the characteristics of a large screen.
일반적으로 편향요크(Deflection yoke)는 음극선관의 네크부에 설치되는 것으로서, 도 1에 도시된 바와 같이 수평편향코일(2)과 수직편향코일(3)의 조합으로구성된다. 즉 서로 분리된 한쌍의 코일세퍼레이터(1) 내주면에 수평편향코일(2)이 설치되고 이의 외주면에 수직편향코일(3)이 설치된다. 또한 수직편향코일(3)의 자계를 보강하기 위해 코일세퍼레이터(1)의 외주면에 서로 분할된 한쌍의 페라이트코어(4)가 구비된다.In general, the deflection yoke is installed in the neck portion of the cathode ray tube, and is composed of a combination of a horizontal deflection coil 2 and a vertical deflection coil 3 as shown in FIG. 1. That is, the horizontal deflection coil 2 is installed on the inner circumferential surface of the pair of coil separators 1 separated from each other, and the vertical deflection coil 3 is installed on the outer circumferential surface thereof. In addition, a pair of ferrite cores 4 are provided on the outer circumferential surface of the coil separator 1 so as to reinforce the magnetic field of the vertical deflection coil 3.
이처럼 구성된 편향요크는 음극선관의 전자총에서 발사된 전자빔을 좌,우측 및 상,하측 방향으로 편향시켜 음극선관의 형광면 상에 형성된 RGB에 충돌시키는 역할을 한다. 또한 최근들어 음극선과의 스크린부가 평면 광각화된에 따라 고난도의 편향기술을 필요로 하게 되었다. 그러나 스크린부의 중앙부와 사각부 주변부로 편향되는 편향거리의 차에 의해 편향요크의 특성중에 하나인 N/S디스토션이 핀자계화 되어 화질이 저하되는 문제점이 있다. 이를 보정하기 위해 종래에는 수직코일의 코일분포 등의 조정에 의해 이를 해결하였으나 한계가 있었다.The deflection yoke configured as described above deflects the electron beam emitted from the electron gun of the cathode ray tube in the left, right and up and down directions to collide with the RGB formed on the fluorescent surface of the cathode ray tube. In addition, recently, as the screen portion with the cathode ray is wide-angled, a high degree of deflection technology is required. However, the N / S distortion, which is one of the characteristics of the deflection yoke, becomes a pin magnetic field due to the difference in the deflection distance that is deflected to the center portion of the screen portion and the periphery of the blind portion. In order to correct this, conventionally, this was solved by adjusting a coil distribution of a vertical coil, but there was a limit.
본 고안은 종래의 여러가지 문제점을 해결하기 위해 안출한 것으로서 본 고안의 목적은 수직코일이 권회되는 페라이트코어의 일부를 가공하여 핀자계가 배럴화 되도록 함으로써, 수직코일의 권선을 조정하지 않더라도 화질이 개선되는 편향요크의 페라이트코어를 제공함에 있다.The present invention has been devised to solve various problems in the related art, and an object of the present invention is to process a part of a ferrite core in which a vertical coil is wound so that the pin magnetic field is barreled, thereby improving image quality even without adjusting the winding of the vertical coil. It is to provide a ferrite core of the deflection yoke.

상기 목적을 달성하기 위하여 본 고안은 코일세퍼레이터의 내주면에 빔을 수평으로 편향시키는 수평편향코일이 구비되고 상기 코일세퍼레이터의 외주면에 수직편향코일과 페라이트코어가 각각 구비되는 편향요크에 있어서, 상기 페라이트코어의 스크린부 쪽에 일정한 곡률반경을 갖는 한쌍의 곡면부를 형성하여 핀자계를 배럴화하는 특징이 있다.In order to achieve the above object, the present invention has a horizontal deflection coil for horizontally deflecting a beam on an inner circumferential surface of a coil separator and a vertical deflection coil and a ferrite core are respectively provided on an outer circumferential surface of the coil separator, wherein the ferrite core is provided. A pair of curved surfaces having a constant radius of curvature is formed on the screen portion of the screen to barrelize the pin magnetic field.
이하 첨부도면에 따라 본 고안의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings in detail.
도 3은 본 고안 페라이트코어의 사시도 로서, 도 1과 동일 구성요소는 동일부호를 사용하여 본 고안을 설명한다. 서로 분리된 한쌍의 코일세퍼레이터(1) 내주면에 수평편향코일(2)이 설치되고 이의 외주면에 수직편향코일(3)이 설치된다. 또한 수직편향코일(3)의 자계를 보강하기 위해 코일세퍼레이터(1)의 외주면에 서로 분할된 한쌍의 페라이트코어(10)가 구비된다.3 is a perspective view of a ferrite core of the present invention, in which the same components as in FIG. 1 will be described using the same reference numerals. A horizontal deflection coil 2 is provided on the inner circumferential surface of the pair of coil separators 1 separated from each other, and a vertical deflection coil 3 is installed on the outer circumferential surface thereof. In addition, a pair of ferrite cores 10 are provided on the outer circumferential surface of the coil separator 1 so as to reinforce the magnetic field of the vertical deflection coil 3.
페라이트코어(10)는 음극선관의 스크린부 쪽으로 한쌍의 곡면부(11)가 구비된다. 이들 곡면부(11)는 높이(ｔ)와 각도(α)에 따라 그 폭이 결정되며 또한 핀자계를 배럴화 하는 량이 달라지는 것으로서 다음 표와 같다.The ferrite core 10 is provided with a pair of curved portions 11 toward the screen portion of the cathode ray tube. The curved portion 11 has a width determined according to the height t and the angle α, and the amount of barreling the pin magnetic field is different, as shown in the following table.
이처럼 구성된 본 고안은 서로 분리된 코일세퍼레이터(1)의 내주면에 수평편향코일(2)이 각각 권회된 다음 이들이 서로 포개져 결합된다. 또한 서로 결합된 코일세퍼레이터(1)의 외주면에 페라이트코어(4)와 수직편향코일(3)이 각각 결합되어 본 고안의 편향요크가 구성된다. 또한 페라이트코어(10)는 음극선관의 스크린부 쪽으로 한쌍의 곡면부(11)가 마련된다. 이들 곡면부(11)는 연마에 의해 형성되며 자속의 집속과 자로를 형성하는 부분이 일부 없어짐으로 곡면부(11)는 정상부분에 비하여 수평자계가 덜 강하게 형성된다. 곡면부(11)는 높이(ｔ)가 15mm이고 각도(α)가 40°인 것이 바람직하다.According to the present invention configured as described above, the horizontal deflection coils 2 are wound on the inner circumferential surface of the coil separator 1 separated from each other, and then they are superimposed and combined with each other. In addition, the ferrite core 4 and the vertical deflection coil 3 are respectively coupled to the outer circumferential surface of the coil separator 1 coupled to each other to constitute the deflection yoke of the present invention. In addition, the ferrite core 10 is provided with a pair of curved portions 11 toward the screen portion of the cathode ray tube. These curved portions 11 are formed by polishing, and part of the magnetic fluxes and magnetic paths are partially removed, so that the curved portions 11 are less strongly formed in the horizontal magnetic field than the normal portions. The curved portion 11 preferably has a height t of 15 mm and an angle α of 40 degrees.
이상에서와 같이 본 고안에 따르면 수직편향코일의 자속을 강화시키는 페라이트코어의 스크린부 쪽에 한쌍의 곡면부를 형성함으로써, 핀자계를 배럴화할수 있다, 그리고 곡면부는 그 높이와 각도에 따라 곡률반경이 결정되며 화면을 보정하는량이 곡률반경에 따라 일정하게 되는 등의 효과가 있다.As described above, according to the present invention, by forming a pair of curved portions on the screen portion of the ferrite core for enhancing the magnetic flux of the vertical deflection coil, the pin magnetic field can be barreled, and the radius of curvature is determined according to its height and angle. The amount of screen correction is constant according to the radius of curvature.
