본 고안은 편향요크용 세퍼레이터에 관한 것으로서, 특히 수평코일의 넥크부측 부위에 철편을 부착하여 3개의 비임을 일치시킴과 아울러 라스터의 왜곡을 좋게 하는 컨버어젼스 보정수단이 부여된 편향요크용 세퍼레이터에 관한 것이다.The present invention relates to a separator for deflection yoke, in particular a deflection yoke separator provided with converging correction means for matching three beams and improving raster distortion by attaching iron pieces to the neck portion of the horizontal coil. It is about.
인라인형 컬러브라운관에 있어서 편향요크가 셀프 컨버어젼스 시스템으로 되어 있는 경우 수평코일의 자계는 핀쿠션형태를 이루게 되고, 수직코일의 자계는 바렐형태를 이루게 된다.In the inline type CRT, when the deflection yoke is a self-convergence system, the magnetic field of the horizontal coil forms a pincushion, and the magnetic field of the vertical coil forms a barrel.
이 경우 R,G,B 3개의 전자비임중 R,B 비임은 일치하지만 G비임은 일치하지 않게 된다.In this case, among the three R, G and B electron beams, the R and B beams coincide, but the G beams do not coincide.
R,B비임과 G비임의 수직방향으로의 어긋남은 수직코일이나 그 외의 장치에 의해 보정되며, 수평방향으로의 어긋남은 전자총에서 보정하는 방식이 있으나 수평코일의 자계분포를 조정할 경우에는 편향요크의 넥크부측 자계를 바렐형으로 해주어야 한다.The deviation of the R, B beam and the G beam in the vertical direction is corrected by a vertical coil or other device. The deviation in the horizontal direction is corrected by an electron gun, but when adjusting the magnetic field distribution of the horizontal coil, The magnetic field on the neck side should be barrel type.
그러나 수평코일에 의한 라스터의 왜곡을 고려할 때 수평 편향 자계는 핀쿠션형태이어야 한다.However, considering the raster distortion caused by the horizontal coil, the horizontal deflection magnetic field should be pincushioned.
종래 인라인형 컬러브라운관에 있어서, R,G,B비임의 수평방향으로의 어긋남을 일치시키기 위한 수단으로 전자총에 필드 컨트롤러를 부착사용하거나, 편향요크의 세퍼레이터 외주에 철편을 부착 사용하여 왔다.Background Art [0002] In the conventional in-line color brown tube, a field controller is attached to the electron gun or a piece of iron is attached to the outer circumference of the separator of the deflection yoke as a means for matching the horizontal deviation of the R, G, and B beams.
이 경우 전자총에 필드 콘트롤러를 부착 사용하게 되면 편향요크의 전,후 이동에 따라 R,G,B 비임의 어긋난 양이 변화되어 조절되고, 세퍼레이터 외주에 철편을 부착 사용하게 되면 국부적인 자계의 변화로 R,G,B 비임의 어긋난 양이 조절되나, 화면의 라스터 왜곡 현상을 방지하는 설계가 어렵게 된다.In this case, if the field controller is attached to the electron gun, the shift amount of the R, G, B beams is adjusted according to the movement of the deflection yoke before and after, and if the iron piece is attached to the outer periphery of the separator, the local magnetic field changes. The shifted amounts of the R, G, and B beams are controlled, but it becomes difficult to prevent raster distortion of the screen.
본 고안은 상기한 문제점을 감안하여 안출한 것으로서, R,G,B 3개의 전자비임을 일치시킴과 아울러 라스터의 왜곡을 방지하고, 설계 자유도를 향상시킬 수 있는 컨버어젼스 보정수단이 부여된 편향요크용 세퍼레이터를 제공함에 그 목적이 있다.The present invention has been devised in view of the above-described problems, and is provided with a convergence correction means for matching R, G and B electron beams, preventing raster distortion, and improving design freedom. The purpose is to provide a separator for deflection yoke.
이의 실현을 위하여 본 고안은 세퍼레이터의 넥크측 접합면 부위에 홈을 형성하고, 이 홈에 철편을 삽입설치하여 구성함을 특징으로 한다.In order to realize this, the present invention is characterized in that a groove is formed at the neck-side joint surface portion of the separator, and an iron piece is inserted into the groove.
이하 본 고안을 첨부한 도면에 의거하여 실시예에 따라 설명하면 다음과 같다.Hereinafter, the present invention will be described according to embodiments based on the accompanying drawings.
제 1 도는 본 고안의 세퍼레이터 일측면을 나타내는 도면으로서 반나팔체로 된 분할 세퍼레이터(1)은 이와 대칭 형상으로 이루어진 또 하나의 분할 세퍼레이터와 조합되어 편향요크 지지체를 형성한다.FIG. 1 is a view showing one side of a separator of the present invention, and the split separator 1 made of a semi-trumpet body is combined with another split separator having a symmetrical shape to form a deflection yoke support.
이 분할 세퍼레이터(1)의 접합면(2)(2')에는 넥크부측으로 홈(3)(3')가 형성되어 있다.Grooves 3 and 3 'are formed on the side of the neck at the joint surfaces 2 and 2' of the split separator 1.
제 2 도의 도시를 통하여 알 수 있듯이 분할 세퍼레이터(1)의 접합면(2)에는 일정깊이의 홈(3)이 형성되어 있고, 이 홈(3)에는 협지돌기(4)가 돌출되어 일체로 형성되어 있다.As shown in FIG. 2, a groove 3 having a predetermined depth is formed in the joining surface 2 of the split separator 1, and the gripping protrusions 4 protrude from the groove 3 to form a single body. It is.
그리고, 분할 세퍼레이터(1)과 접합되는 또 다른 분할 세퍼레이터(1a)의 접합면(5)에는 홈(3)과 같은 위치에 홈(6)이 형성되어 있다.And the groove | channel 6 is formed in the position similar to the groove | channel 3 in the bonding surface 5 of the other separator 1a joined with the division separator 1.
또한, 접합면(2')와 접합되는 분할 세퍼레이터에도 같은 위치에 전기한 바와 동일한 구성의 협지돌기가 돌출되어 있는 홈이 형성되어 있다.Moreover, the groove | channel in which the clamping protrusion of the same structure as what was electricly protruded in the same position is also formed in the split separator joined with the joining surface 2 '.
전기한 홈(3)에 돌출되어 있는 협지돌기(4)에는 협지공(7)이 뚫어진 철편(8)이 삽입설치된다.In the pinching protrusion 4 which protrudes in the groove 3 mentioned above, the iron piece 8 through which the pinching hole 7 was drilled is inserted.
이와 같은 방식으로 해서 분할 세퍼레이터(1)과 (1a)의 접합면(2)와 (5)부위에 철편(8)이 설치되고, 반대측의 접합면(2')부위와 접합되는 홈(3')에도 또 다른 철편이 설치된다.In this manner, the iron piece 8 is provided on the joining surfaces 2 and 5 of the split separators 1 and 1a, and the groove 3 'is joined to the joining surface 2' on the opposite side. ) Another piece of iron is installed.
이와 같이 구성되는 본 고안은 철편(8)이 세퍼레이터의 넥크측 부위에 설치됨에 따라 수평코일에 한 자계분포가 제 3 도의 도시와 같이 이루어진다.According to the present invention configured as described above, as the iron piece 8 is installed at the neck-side portion of the separator, a magnetic field distribution on the horizontal coil is made as shown in FIG.
즉, 철편(8)의 부착 영역에서 자계가 더욱 바렐형으로 되어있는 것이다.That is, the magnetic field becomes more barrel-shaped in the attachment region of the iron piece 8.
따라서, R,G,B 3개의 전자비임이 일치되고 라스터의 왜곡현상도 방지된다.Therefore, the three electron beams of R, G, and B coincide with each other and distortion of the raster is also prevented.
또한 본 고안은 철편을 세퍼레이터에 홈을 형성하여 설치하므로서 설계자유도를 향상시킬 수 있는 이점도 있다.In addition, the present invention has the advantage of improving the design freedom by forming a groove in the separator to form a groove.
