본 고안은 컬러브라운관용 편향요크에 관한 것으로서 특히 셀프컨버젼스형 편향요크에서 나타나는 핀쿠션형 디스토션을 보정할 수 있도록 한 것이다.The present invention relates to a deflection yoke for color-brown tubes, and particularly to correct pincushion-type distortion in a self-converged deflection yoke.

종래 컬러브라운관용 편향요크(2)는 제1도 및 제3도와 같이 전자총에서 나온 전자빔을 수평방향으로 편향시켜주기 위한 수평코일(3)과, 수직방향으로 편향시켜주기 위한 수직코일(4)과, 상기 코일에서 발생된 자기력의 손실을 줄여주어 자기 효율을 높여주는 페라이트코아(5)와, 상기 수직/수평코일(3)(4)사이를 절연시켜주는 홀더(6)를 구성하였다.The deflection yoke 2 for the conventional color brown tube includes a horizontal coil 3 for deflecting the electron beam emitted from the electron gun in the horizontal direction, and a vertical coil 4 for deflecting in the vertical direction, as shown in FIGS. 1 and 3. To reduce the loss of the magnetic force generated in the coil to increase the magnetic efficiency of the ferrite core (5) and the holder (6) to insulate between the vertical / horizontal coil (3) (4).

도면중 미설명부호 7은 마그네트이고 8은 필드세이퍼(FIELD SHAPER)를 나타낸다.In the drawings, reference numeral 7 denotes a magnet, and 8 denotes a field shaper.

이와같이 구성된 셀프컨버젼스형 편향요크(2)는 화면상에 제3도와 같은 핀쿠션형 디스토션이 나타나며 이를 보정하기 위해서는 편향요크(2)이 화면쪽 개구부의 수직편향자계가 제4도 같은 넥크부는 바렐자계, 개구부는 핀자계 형상을 가져야 한다. 이는 전자빔이 자계의 오른쪽 수직방향으로 힘을 받기 때문에 제5도와 같은 핀쿠션형자계가 핀쿠션형 디스토션을 보정하는데 유리하기 때문이다. 따라서 개구부쪽에 이와같은 핀쿠션형자계를 헝성하기 위해 편향요크(2)의 개구부쪽 홀더에 마그네트(7)를 부착하거나 크로스아암 같은 부재를 설치하는 등의 방법을 채택하여왔다.The self-converged deflection yoke 2 configured as described above has a pincushion-type distortion as shown in FIG. 3 on the screen. The opening should have a pin magnetic field shape. This is because the pincushion type magnetic field as shown in FIG. 5 is advantageous in correcting the pincushion type distortion because the electron beam is forced in the right vertical direction of the magnetic field. Therefore, in order to form such a pincushion type magnetic field in the opening side, the magnet 7 is attached to the opening holder of the deflection yoke 2, or a member such as a cross arm has been adopted.

종래의 핀쿠션형 이스토션을 보정하는 방법중 마그네트(7)를 사용하는 경우는 편향요크(2)의 개구부쪽 홀더에 마그네트를 부착하여 국부적으로 개구부자계를 핀쿠션자계로 만들어주어 디스토션을 보정한다. 반면 크로스아암 방식은 크로스아암 그 자체가 자계를 발생하는 능동소자가 아인 개구부의 누설자계를 이용하는 수동소자로 개구부쪽 수직방향자계를 핀쿠션형태로 바꾸어주어 좌우디스토션을 보정한다. 그리고 토로이달형 수직코일의 경사권방식을 채택하는 경우는 코아에 권선되는 각도를 경사지게 하여 개구부쪽 전단부에 권선되는 폭을 넥크쪽보다 좁게 하고, 넥크부에는 필드세이퍼로 바렐자계를 만들어 준다. 개구부쪽 권선폭이 좁아짐에 따라 개구부 수식편향자게가 핀쿠션자계로 되어 디스토션을 보정하면서, 수직편향자계에 의해서 좌우디스토션이 완전히 보정할 수 없으므로 제2도와 같은 마그네트(7)를 사용하여 보정한다.When the magnet 7 is used in the conventional pincushion type correction method, a magnet is attached to the opening holder of the deflection yoke 2 to locally make the opening magnetic field a pincushion magnetic field, thereby correcting the distortion. On the other hand, the cross arm method is a passive element using the leakage magnetic field of the opening where the cross arm itself generates the magnetic field, and corrects the left and right distortion by changing the vertical magnetic field on the opening side into a pin cushion type. In case of adopting the inclination winding method of the toroidal vertical coil, the angle wound on the core is inclined to make the width wound on the front end of the opening narrower than the neck side, and the barrel part is made of a field magnetic with the field safer. As the winding width of the opening is narrowed, the opening deflection deflection gage becomes a pincushion magnetic field, while the left and right distortion cannot be completely corrected by the vertical deflection field, and thus the magnet 7 as shown in FIG. 2 is used for correction.

그러나 이러한 마그네트 부착의 경우 양산시 작업에 따른 품질산포가 크며 국부적인 자계로 인한 미스컨버젼스를 유발시키기도 하고 크로스아암을 이용하는 경우 크로스아암의 고정이 어렵고 S/S형 편향요크(2)의 경우에는 이용이 불가능하다. 또한 경사권방식의 경우에 있어서는 개구부의 코일이 미끄러짐현상에 의하여 자계분포가 면화하고 컨버젼스의 변화가 심하게 되는등의 문제점이 있었다.However, in case of attaching magnet, quality distribution is large according to the work in mass production, and it may cause misconvergence due to local magnetic field. In case of using cross arm, it is difficult to fix cross arm and in case of S / S type deflection yoke (2) impossible. In addition, in the case of the slope winding method, there is a problem that the magnetic field distribution becomes cotton due to the sliding phenomenon of the opening and the change of convergence is severe.

본 고안은 이러한 점을 감안하여 편향요크에 의해 전자빔이 편향될때 나타나는 좌우핀쿠션형 디스토션을 보정하돌고 두개로 분할된 페라이트코아와, 상기 페라이트코아에 수직편향전류가 인가되도록 권선된 수직편향코일을 구비함으로서, 필드 세이퍼의 사용을 배제할 수 있어서 소음에 대한 문제를 해결하고 능동소자(편향코일)의 사용에 의한 컨버젼스를 개선하도록 하는데 목적이 있다.In view of the above, the present invention compensates for the left and right pincushion-type distortion that occurs when the electron beam is deflected by the deflection yoke. By doing so, it is possible to eliminate the use of the field saver to solve the noise problem and to improve the convergence by the use of an active element (deflection coil).

본 고안의 구성을 제6도에 의하여 설명한다.The configuration of the present invention will be described with reference to FIG.

페라이트코아를 도면과 같이 넥크부 페라이트코아(109)와 개구부 페라이트코아(110)의 두개로 분할하고, 상기 페라이트코아의 내외곡면은 종래와 같이 구성한다.The ferrite core is divided into two, the neck portion ferrite core 109 and the opening ferrite core 110, as shown in the figure, the inner and outer curved surfaces of the ferrite core is configured as in the prior art.

그리고 상기 페라이트코아에 권선되는 수직편향코일은 강한 핀자계을 만들어주어 디스토션을 보정하는 객구부 수직편향코일(104)과, 바렐자계를 만들어주어 컨버젼스를 보정하는 넥크부 수직편향코일(103)을 구비하였다.In addition, the vertical deflection coil wound around the ferrite core is provided with a customer part vertical deflection coil 104 for correcting distortion by making a strong pin magnetic field, and a neck part vertical deflection coil 103 for correcting convergence by creating a barrel magnetic field. .

그리고 상기 수직편향코일은 병렬 혹은 직렬로 결선하고 턴수를 동일하게 하여 넥크부 수직 편향코일(103)과 개구부 수직편향코일(104)에 동일한 전류가 흐르도록 하였다.In addition, the vertical deflection coils were connected in parallel or in series and the same number of turns so that the same current flows through the neck part vertical deflection coil 103 and the opening vertical deflection coil 104.

이와같이 구성된 본 고안 편향요크는 개구부 수직편향코일(104)에서 강한 판자계를 만들어 주어 좌우디스토션을 보정하도록 한다. 즉 종래 수직편향코일에 개구부 핀자계를 만들어 주고 또한 마그네트를 사용하여 디스토션을 보정하는 크기로 본 고안에서는 개구부 수직편향코일(104)의 핀자계를 보정한다.The invention yoke deflection yoke configured as described above makes a strong plank system in the opening vertical deflection coil 104 to correct the left and right distortion. That is, the present invention corrects the pin magnetic field of the opening vertical deflection coil 104 in the present invention to the size to make the opening pin magnetic field in the conventional vertical deflection coil and to correct the distortion using the magnet.

또 넥크부 수직편향코일(103)은 바렐자계를 만들어 주는데 개구부 수직편향코일(104)에서 핀자계를 만들어 주는 것보다 더 큰 바렐자계가 되도록 하여 컨버젼스를 보정한다.In addition, the neck portion of the vertical deflection coil 103 generates a barrel magnetic field, so that the convergence is corrected by making the barrel magnetic field larger than the pin magnetic field in the opening vertical deflection coil 104.

즉 개구부 수직편향코일(104)은 디스토션을 보정하고 넥크부 수직편향코일(103)은 컨버젼스를 보상하게 된다.That is, the opening vertical deflection coil 104 corrects the distortion and the neck vertical deflection coil 103 compensates for the convergence.

이와같은 본 고안은 필드 세이퍼를 사용하지 않으므로 소음에 대한 문제를 해결할수 있고 또한 수동소자(필드세이퍼, 마그네트)를 사용하지 않고 능동소자(편향코일)만 사용하므로 컨버젼스 문제를 개선할수 있는 고안이다.The present invention is designed to solve the problem of noise because it does not use a field saver, and also improves the convergence problem because only active elements (deflection coils) are used without using passive elements (field savers, magnets).
