본 고안은 편향요크의 수평편향코일 구조에 관한 것으로서, 더욱 상세하게는 수평편향코일의 네크쪽 코일 분포를 조정함으로써, HCR 특성(CRT 화면의 X축상의 R/B 중심과 Green과의 수평방향의 미스콘버젼스)이 조정되도록 한 편향요크의 수평편향코일 구조에 관한 것이다.The present invention relates to a horizontal deflection coil structure of a deflection yoke, and more particularly, by adjusting the neck coil distribution of the horizontal deflection coil, the HCR characteristic (the horizontal direction of the R / B center on the X axis of the Misconvergence) is related to the horizontal deflection coil structure of the deflection yoke.

일반적으로 편향요크(Deflection Yoke)는 CRT의 네크에 설치되는 것으로서, 제 1 도에 도시된 바와 같이 수평편향코일(2)과 수직편향코일(3)의 조합으로 구성되며 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 on the neck of the CRT, and a pair of coil separators composed of a combination of a horizontal deflection coil 2 and a vertical deflection coil 3 and separated from each other as shown in FIG. (1) A horizontal deflection coil 2 is provided on the inner circumferential surface and a vertical deflection coil 3 is provided 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 CRT의 전자총에서 발사된 전자빔을 좌, 우측 및 상, 하측 방향으로 편향시켜 CRT의 형광면 상에 형성된 RGB에 충돌시키는 역할을 한다. 또한 수평, 수직편향코일(2)(3)이 코일세퍼레이터(1)에 조립된 상태에서 HCR 특성을 보정하기 수평편향코일(2)의 네크(5)에 바페라이트(bar ferrite)를 설치하였다.The deflection yoke configured as described above deflects the electron beam emitted from the electron gun of the CRT in left, right, up and down directions to collide with the RGB formed on the fluorescent surface of the CRT. In addition, bar ferrites were installed on the neck 5 of the horizontal deflection coil 2 to correct the HCR characteristics in a state in which the horizontal and vertical deflection coils 2 and 3 were assembled to the coil separator 1.

그러나 XH {수평편향코일의 자계성분인 베럴자계 및 핀자계에 기인하는 틸트(tilt)성분}특성이 HCR 특성보다 2배 정도 많이 변하기 때문에 HCR 특성 개선효과만 있고 N/S 디스토션, 랜딩특성의 개선에는 효과가 없는 단점이 있다.However, the XH {tilt component due to the magnetic field component of the horizontal deflection coil and the pin magnetic field} changes twice as much as the HCR characteristic, so it has only the effect of improving the HCR characteristics and the improvement of N / S distortion and landing characteristics. There is a disadvantage that does not work.

본 고안은 종래의 문제점을 해결하기 위해 안출한 것으로서 본 고안의 목적은 수평편향코일의 네크에서 윈도우부의 코일분포를 많게 하고 프레스부의 코일분포를 적게 함으로써, 네크에서 베럴자계를 유도하여 HCR 특성이 개선되도록 한 편향요크의 수평편향코일 구조를 제공함에 있다.The present invention was devised to solve the conventional problems, and an object of the present invention is to increase the coil distribution of the window portion in the neck of the horizontal deflection coil and reduce the coil distribution of the press portion, thereby inducing a barrel magnetic field in the neck to improve HCR characteristics. To provide a horizontal deflection coil structure of the deflection yoke as possible.

상기 목적을 달성하기 위하여 본 고안은 코일세퍼레이터의 내주면에 전자빔을 수평방향으로 편향시키는 수평편향코일이 설치됨에 있어서, 상기 수평편향코일의 후단에 윈도우부와 프레스부를 갖는 네크가 구비되고 상기 윈도우부의 코일분포가 상기 프레스부의 코일분포보다 커지도록 하여 상기 윈도우부에 베럴자계를 유도하는 보정수단이 구비된 특징이 있다.In order to achieve the above object, the present invention provides a horizontal deflection coil for deflecting an electron beam in a horizontal direction on an inner circumferential surface of a coil separator. A neck having a window part and a press part is provided at a rear end of the horizontal deflection coil, and the coil of the window part is provided. The distribution means is larger than the coil distribution of the press portion, characterized in that the correction means for inducing a barrel magnetic field in the window portion.

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 as follows.

제 3 도는 본 고안의 수평편향코일의 사시도로서, 제 1 도와 동일 구성요소는 동일 부호를 사용하여 본 고안을 설명한다. 수평편향코일(10)은 선단의 스크린(11)과 후단의 네크(12)로 분리 구성된다. 또한 네크(12)는 상측에 베럴자계를 일으키는 윈도우부(13)가 구비되고 하측에 핀자계를 일으키는 프레스부(14)가 각각 구비된다. 또한 윈도우부(13)의 코일분포가 프레스부(14)보다 크도록 하여 네크(12)에서 베럴자계를 유도하는 보정수단(16)이 구비된다. 보정수단(16)에 따르면 HCR 특성을 개선할 때 다른 특성 예컨대 N/S 디스토션, 랜딩 특성 등이 함께 개선된다. 이러한 보정수단(16)은 네크(12) 후단의 네크밴트(15) 하단에 프레스부(14) 쪽으로 연장된 돌출부(17)가 구비된다. 돌출부(17)에 의해 프레스부(14) 쪽의 코일분포가 윈도우부(13) 보다 상대적으로 작아져 네크(12)에서 윈도우부(13)이 베럴자계가 유도된다.Figure 3 is a perspective view of a horizontal deflection coil of the present invention, the first diagram and the same components to describe the present invention using the same reference numerals. The horizontal deflection coil 10 is divided into a screen 11 at the front end and a neck 12 at the rear end. In addition, the neck 12 is provided with a window portion 13 for generating a barrel magnetic field on the upper side and a press portion 14 for generating a pin magnetic field on the lower side, respectively. Further, correction means 16 for inducing a barrel magnetic field in the neck 12 are provided so that the coil distribution of the window portion 13 is larger than the press portion 14. According to the correction means 16, when the HCR characteristic is improved, other characteristics such as N / S distortion, landing characteristic, and the like are also improved. The correction means 16 is provided with a protrusion 17 extending toward the press portion 14 at the lower end of the neckband 15 behind the neck 12. The coil portion on the side of the press portion 14 is smaller than the window portion 13 by the protruding portion 17 so that the barrel portion of the window portion 13 is induced in the neck 12.

이처럼 구성된 본 고안은 네크밴트(15) 하단이 프레스부(14) 쪽으로 연장된 돌출부(17)가 구비됨으로 프레스부(14)의 코일분포가 윈도우부(13) 보다 작아진다. 이 같은 수평편향코일(10)이 코일세퍼레이터(1)에 조립된 상태에서 화면특성이 조정되면 네크(12) 쪽은 배럴자계가 유도된다. 따라서 HCR 특성을 조정할 때 네크(12) 쪽에 배럴자계가 유도됨으로 다른 특성이 함께 개선된다. 또한 HCR 특성을 조정하기 위해 별도의 바페라이트 등을 사용할 필요가 없다.The present invention configured as described above has a protrusion 17 extending toward the press portion 14 at the lower end of the neckband 15, so that the coil distribution of the press portion 14 is smaller than that of the window portion 13. When the screen characteristic is adjusted while the horizontal deflection coil 10 is assembled to the coil separator 1, the barrel magnetic field is induced on the neck 12 side. Therefore, when adjusting the HCR characteristic, the barrel magnetic field is induced on the neck 12 side, so that other characteristics are improved together. In addition, there is no need to use a separate bar ferrite or the like to adjust the HCR characteristics.

이상에서와 같이 본 고안에 따르면 수평편향코일의 네크 쪽에 형성된 윈도우부의 코일분포가 프레스부의 코일분포보다 많아지도록 하기 위해 네크밴트의 하단이 프레스부 쪽으로 연장되도록 함으로써, 네크에서 배럴자계가 유도된다. 따라서 화면특성을 조정할 때 HCR 특성을 개선시키면 다른 화면특성이 함께 개선되는 효과가 있고 또한 HCR 특성을 개선하기 위해 별도의 바페라이트 등을 사용할 필요가 없어 조립성이 향상되는 등의 효과가 있다.As described above, according to the present invention, the barrel magnetic field is induced in the neck by extending the lower end of the neckband toward the press part so that the coil distribution of the window part formed on the neck side of the horizontal deflection coil is larger than the coil distribution of the press part. Therefore, when the screen characteristic is adjusted, the improvement of the HCR characteristic has the effect of improving the other screen characteristics together, and there is an effect of improving the assemblability since there is no need to use a separate bar ferrite or the like to improve the HCR characteristic.
