Description
본 고안은 편향요크의 틸트코일에 관한 것으로서, 더욱 상세하게는 틸트코일이 감기는 보빈의 내부에 코일의 권회방향을 유도하는 수단을 구비함으로써, 권선이 균일하게 이루어져 보정효과가 향상되는 편향요크의 틸트코일에 관한 것이다.The present invention relates to a tilt coil of a deflection yoke, and more particularly, a means for inducing a winding direction of a coil inside a bobbin to which the tilt coil is wound, whereby the winding is uniform and the correction effect of the yoke is improved. It relates to a tilt coil.
일반적으로 편향요크(Deflection Yoke)는 음극선관의 네크부에 설치되는 것으로서, 도 1에 도시된 바와 같이 수평편향코일(2)과 수직편향코일(3)의 조합으로 구성된다. 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, 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 코일세퍼레이터(1)의 스크린부에는 지자계에 의한 화상회전(raster rotation)을 보정하기 위한 틸트코일(6)이 사용된다. 도 2에 도시된 바와 같이 코일세퍼레이터(1)의 스크린부와 같은 직경을 갖는 보빈(5)의 외주면에 틸트코일(6)이 일정량 권회되고 이러한 코일에 의해 화상회전이 보정된다.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, a tilt coil 6 for correcting raster rotation caused by a geomagnetic field is used for the screen portion of the coil separator 1. As shown in Fig. 2, the tilt coil 6 is wound around the outer circumferential surface of the bobbin 5 having the same diameter as the screen portion of the coil separator 1, and the image rotation is corrected by this coil.
그러나 보빈(5)의 외주면이 평면으로 구성됨으로 틸트코일(6)의 권회시 코일(6)이 불균일하게 권회되어 서로 엉키게 되면 화면보정이 제품마다 틀리게 나타나게 되어 신뢰성이 저하되는 등의 단점이 있다.However, since the outer circumferential surface of the bobbin 5 has a flat surface, when the coils 6 are wound unevenly when the tilt coil 6 is wound up, the screen correction appears wrong for each product, and thus there is a disadvantage in that reliability is lowered. .
본 고안은 종래의 여러가지 문제점을 해결하기 위해 안출한 것으로서 본 고안의 목적은 코일세퍼레이터의 스크린부에 설치되는 틸트코일이 균일하게 권회되어 적층되도록 이를 감는 보빈에 코일의 권회를 안내하는 수단을 마련함으로써, 틸트코일에 의한 화면보정이 균일하도록한 편향요크의 틸트코일을 제공함에 있다.The present invention has been devised to solve various problems of the prior art, and an object of the present invention is to provide a means for guiding the winding of a coil in a bobbin wound around the coil so that the tilt coil installed on the screen of the coil separator is uniformly wound and stacked. In addition, the present invention provides a tilt coil of a deflection yoke, which makes the screen correction by the tilt coil uniform.

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 틸트코일의 단면도 로서, 도 1과 동일 구성요소는 동일 부호를 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(4)가 구비된다. 그리고 코일세퍼레이터(1)의 스크린부에 이의 직경과 동일한 직경을 갖는 보빈(10)이 구비된다. 보빈(10)은 지자계에 의한 화상회전을 보정하기 위한 틸트코일(12)이 감기는 것으로 틸트코일(12)이 균일하게 권회도록 하는 수단이 구비된다. 이러한 수단은 보빈(10)의 외주면에 형성된 가이드홈(11)에 의해 형성된다. 가이드홈(11)은 틸트코일(12)의 직경과 동일한 직경을 갖는 반원호형의 요홈으로 구성되며 이들 가이드홈(11)이 균일하게 다수열 배열된다.Figure 3 is a cross-sectional view of the tilt coil of the present invention, the same components as in Figure 1 will be described the present invention 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 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. And the bobbin 10 which has the diameter same as its diameter is provided in the screen part of the coil separator 1. As shown in FIG. The bobbin 10 is provided with means for allowing the tilt coil 12 to be uniformly wound by winding the tilt coil 12 for correcting image rotation caused by the geomagnetic field. This means is formed by a guide groove 11 formed on the outer circumferential surface of the bobbin 10. The guide grooves 11 are composed of semi-circular arc-shaped grooves having the same diameter as that of the tilt coil 12, and these guide grooves 11 are uniformly arranged in a plurality of rows.
이처럼 구성된 본 고안의 편향요크는 음극선관의 전자총에서 발사된 전자빔을 좌,우측 및 상,하측 방향으로 편향시켜 음극선관의 형광면 상에 형성된 RGB에 충돌시키는 역할을 한다. 또한 코일세퍼레이터(1)의 스크린부에는 화상회전을 보정하기 위한 틸트코일(12)이 구비된다. 틸트코일(12)은 보빈(10)의 외주면에 다수열 권회되어 적층된다. 그리고 권회되는 과정에서 보빈(10)의 외주면에 형성된 가이드홈(11)에 순착적으로 감긴 상태로 적층됨으로 코일의 엉킴이 방지되고 화면의 보정이 제품마다 균일해진다.The deflection yoke of the present invention configured as described above serves to collide with the RGB formed on the fluorescent surface of the cathode ray tube by deflecting the electron beam emitted from the electron gun of the cathode ray tube in left, right and up and down directions. In addition, a tilt coil 12 for correcting image rotation is provided at the screen portion of the coil separator 1. The tilt coils 12 are wound and stacked in multiple rows on the outer circumferential surface of the bobbin 10. In addition, the coil is prevented from being entangled and stacked on the guide groove 11 formed on the outer circumferential surface of the bobbin 10 in the winding process, and the screen correction is uniform for each product.
이상에서와 같이 본 고안에 따르면 코일세퍼레이터의 스크린부에 화면회전을 보정하기 위한 틸트코일이 구비된다. 틸트코일은 스크린부와 동일한 직경을 갖는 보빈의 외주면에 감기게 되며 이때 보빈에는 틸트코일을 균일하게 정열된 상태로 감을수 있는 가이드홈이 다수열 배열돼 있다. 따라서 보빈에 감긴 틸트코일이 서로 엉키게 되지 않으므로 제품마다 화면의 보정이 균일해져 신뢰성이 향상되는 등의 효과가 있다.As described above, according to the present invention, a tilt coil for correcting screen rotation is provided on the screen portion of the coil separator. The tilt coil is wound on the outer circumferential surface of the bobbin having the same diameter as the screen portion, and the bobbin has a plurality of guide grooves for winding the tilt coil in a uniformly aligned state. Therefore, since the tilt coils wound on the bobbin are not tangled with each other, the screen is uniformly calibrated for each product, thereby improving reliability.
