A characteristic diagram showing the characteristics.
그리고 이하에서는 도 1을 참조하여 설명하며 동일부품에는 동일한 부호를 부여하였다.Hereinafter, a description will be given with reference to FIG. 1 and like reference numerals refer to like parts.
먼저 도 1을 참조하면, 좌,우 대칭형으로 되어 하나로 합체되는 한쌍의 코일 세퍼레이터(10)을 구비한다.First, referring to FIG. 1, a pair of coil separators 10, which are symmetrical left and right, are merged into one.
코일 세퍼레이터(10)는, 음극선관의 스크린면에 결합되는 스크린부(11)와, 리어 커버(rear cover;12) 및 이 리어 커버(12)의 중심면으로부터 일체로 연장 형성되어 음극선관의 전자총부에 결합되는 네크부(13)로 이루어진다.The coil separator 10 is integrally formed from the screen portion 11 coupled to the screen surface of the cathode ray tube, the rear cover 12 and the center surface of the rear cover 12 to form electrons of the cathode ray tube. It consists of a neck 13 coupled to the gun.
코일 세퍼레이터(10)의 내,외주면에는 수평편향자계와 수직 편향자계를 형성하기 위한 수평편향코일(100)과 수직편향코일(15)이 각각 마련된다.The inner and outer circumferential surfaces of the coil separator 10 are provided with a horizontal deflection coil 100 and a vertical deflection coil 15 to form a horizontal deflection magnetic field and a vertical deflection magnetic field, respectively.
그리고 수직편향코일(15)을 통한 수직자계를 강화시키기 위한 페라이트코어(16)가 마련된다.And a ferrite core 16 for strengthening the vertical magnetic field through the vertical deflection coil 15 is provided.
한편, 전술한 수평편향코일(100)은 실질적으로 본 발명의 특징적인 요소를 갖고 있는 것으로서, 그 상세한 구조를 보면, 전면 일측에는 즉, 스크린부측 중심부에는 자계 약화를 위한 홈부(110)가 마련되며, 후면에는 네크부가 마련된다.On the other hand, the above-described horizontal deflection coil 100 as having substantially the characteristic elements of the present invention, when looking at the detailed structure, the groove portion 110 for weakening the magnetic field is provided on one side of the front surface, that is, the center of the screen portion side Neck is provided on the back.
이 홈부(110)는 도 3에서와 같이 그 형성각도는 0'＜ θ ＜ 20' 범위에서 형성된다.As shown in FIG. 3, the groove 110 is formed at an angle of 0 '<θ <20'.
또한 홈부(110)의 깊이를 t라 할 때 1㎜＜ t ＜10㎜ 범위내에서 형성되도록 함이 바람직하다.In addition, when the depth of the groove 110 is t, it is preferable to be formed within the range of 1 mm <t <10 mm.
이와같이 수평편향코일(100)의 전면부 즉, 스크린부의 중심부에 홈부(110)를 형성함에 의해서는, 감도 향상을 통한 소비전력을 줄일 수 있게된다.Thus, by forming the groove 110 in the front portion of the horizontal deflection coil 100, that is, the center of the screen portion, it is possible to reduce the power consumption by improving the sensitivity.
또한 전면부의 자계가 약화됨으로써, 디스토션의 핀(PIN)화 되어 도 4에서와 같이 화면상의 왜곡이 점선으로 나타내 보인 바와 같이 개선되는 효과를 얻게된다.In addition, as the magnetic field of the front part is weakened, the pin of the distortion is reduced, so that the distortion on the screen is improved as shown by a dotted line as shown in FIG. 4.
또한 S3V가 배럴(BARREL)화 됨으로써 도 5에서와 같이 컨버젼스 특성이 개선되는 효과를 얻게된다.In addition, as S3V is barreled, the convergence characteristic is improved as shown in FIG. 5.
상술한 바와 같이 본 발명에 따른 편향요크에 의하면 다음과 같은 효과를 얻는다.As described above, according to the deflection yoke according to the present invention, the following effects are obtained.
첫째, 수평편향코일의 스크린부 중심부측에 마련된 홈부를 통해 자계를 약화시켜 감도 향상을 통한 소비전력을 줄일 수 있는 이점이 있다.First, there is an advantage that the magnetic field is weakened through the groove provided in the center portion of the screen portion of the horizontal deflection coil, thereby reducing power consumption through improved sensitivity.
둘째, 디스토션이 핀화 됨으로써 화면상의 왜곡을 보정할 수 있는 이점이 있다.Second, there is an advantage that the distortion on the screen can be corrected by distortion.
셋째, S3V가 배럴화 됨으로써 컨버젼스 특성을 조정하기가 용이한 이점이 있다.Third, there is an advantage that it is easy to adjust the convergence characteristics by the barreled S3V.
