* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 편향요크 11 : 라인홈1: deflection yoke 11: line groove

12 : 보정자성유니트 13 : 플렌지12: correction magnetic unit 13: flange

본고안은 칼라수상관용 편향요크와 관련된 것으로서, 좀더 상세히는 상기 편향요크측의 플렌지부위에 미스콘버젼스 보정기능의 보정자성 유니트를 선택적으로 부착가능케 되는 라인홈부를 구비시킨 편향요크에 관한 것이다.The present invention relates to a deflection yoke for a color receiving tube, and more particularly, to a deflection yoke having a line groove portion for selectively attaching a correction magnetic unit having a misconvergence correction function to a flange portion on the deflection yoke side.

이러한 기술분야의 칼라수상관 편향요크는 제1도와 같이 나타내었다.The color water pipe deflection yoke of this technical field is shown in FIG.

여기서는 칼라수상관의 퍼늘(2)부로부터 이어진 목부(7)에 정집중 조립기체(6), 편향요크(5), 새도마스크(4)등이 포함된 형태로 되고, 우전면축의 패널(3) 내면에 형광막(8)이 도포되어진 형태로 된다. 그리고, 상기 편향요크(5)는 칼라수상관 제작시 노광으로 형성된 R, G, B 화소에 전자총측의 3전자빔이 화면 전체에 정확히 랜딩되어지도록 칼라수상관의 퍼늘(2)와 목부(7)로 이어지는 사이에 위치고정된다.In this case, the neck (7) connected to the perimeter (2) of the color water pipe includes a concentrated assembly body (6), a deflection yoke (5), a shadow mask (4), and the like. 3) The fluorescent film 8 is coated on the inner surface. In addition, the deflection yoke 5 includes the perimeter 2 and the neck 7 of the color receiving tube so that the three electron beams on the electron gun side are accurately landed on the entire screen in the R, G, and B pixels formed during exposure during the manufacturing of the color receiving tube. The position is fixed in between.

즉, 여기서는 칼라수상관 화면 전체의 퓨리티(Purity)는 편향요크(5)를 상기 위치에 고정시킨 상태에서 편향요크(5)의 자기장으로 3 전자빔을 편향시키면서 칼라수상관의 새도우마스크(4) 한점으로 컨버젼스 시킴으로서 달성되어 질수 있다.In other words, here, Purity of the entire color receiver screen is one point of the shadow mask 4 of the color receiver tube while deflecting three electron beams with the magnetic field of the deflection yoke 5 while the deflection yoke 5 is fixed at the position. Can be achieved by convergence.

그러나, 상기와 같은 기술에서 인라인 배열의 3 전자빔이 정확히 편향요크(5)측의 편향 중심을 통과하는 이상적인 경우에 그 정확한 퓨리티 조건을 부여가능케 되는 것이나, 현실에 있어서는 상기 칼라수상관의 제작과정에서 발생하는 여러요인으로 전자빔이 상기 편향요크(5)의 중심점을 통과하지 못하는 경우가 많은 것이었다.However, in the above technique, it is possible to impart the exact purity condition in the ideal case where three electron beams of the in-line array pass exactly through the deflection center on the deflection yoke 5 side, but in reality, in the manufacturing process of the color receiver, In many cases, the electron beam did not pass through the center point of the deflection yoke 5.

즉, 제2도의 (a)(b)에선 상기 편향요크(5)측의 핀큐션 자계와 배럴자계를 나타내었다.That is, in Fig. 2 (a) and (b), the pincushion magnetic field and the barrel magnetic field on the deflection yoke 5 side are shown.

그리고, 여기서의 핀쿠션 및 배럴자계의 영향으로 여러가지 미스컨버젼스 패턴이 화면상에 출현하게 되고, 이는 편향요크(5)를 조정하므로서 보정가능케 된다.In addition, various misconvergence patterns appear on the screen under the influence of the pincushion and barrel magnetic field, which can be corrected by adjusting the deflection yoke 5.

그러나, 여기서는 상기 편향요크(5)의 조정에 의해 그 미스컨버젼스를 보정할 수 있지만 모든 경우에 항상 만족된 다이나믹(dynamic) 컨버젼스를 행할 수 없으므로 이로인한 문제점이 있었던 것이었다.However, here, the misconvergence can be corrected by the adjustment of the deflection yoke 5, but there is a problem due to the fact that dynamic convergence cannot be always performed in all cases.

또, 편향요크(5) 제작 과정중 발생될수 있는 오차등으로 인하여 생긴 미스컨버젼스는 퍼늘(2)부에 자성체를 붙여 전자빔을 관축방향으로 또는 그 반대방향으로 이동시켜 컨버젼스를 조정하는 수단도 있을수 있으나, 이 또한 퍼늘부에 별도의 자성체를 부착하는 것은 그 구조적 복잡성이 수반되고 그 사용상의 불리함이 증가되어 바람직한 형태로 기대되기 어려운 것이었다.In addition, the misconvergence caused by errors that may occur during the manufacturing process of the deflection yoke 5 may have a means of adjusting the convergence by attaching a magnetic material to the perimeter 2 to move the electron beam in the tube axis direction or vice versa. In addition, attaching a separate magnetic material to the permeable part was accompanied by its structural complexity and its disadvantages of use, which was difficult to be expected in a preferred form.

본 고안은 상기와 같은 종래 문제점을 개선하고저 안출된 것이다.The present invention improves on the conventional problems as described above and is designed.

본 고안은 그 목적이 편향요크측의 미스컨버젼스를 편향요크 플랜지측에서 선택적으로 조정가능케 되므로서 그 편리성 및 고품위의 화질제공이 가능케 되는 편향요크를 제공코저 한 것이다.The object of the present invention is to provide a deflection yoke which enables the misconvergence of the deflection yoke side to be selectively adjusted on the deflection yoke flange side, thereby providing convenience and high quality image quality.

본고안은 특히 편향요크의 프랜지 부위에 라인홈을 구비하고 이에 선택적으로 보정자성 유니트를 조립가능케하는 구성을 그 특징으로 하는 것이다.In particular, the present invention is characterized by having a line groove at the flange portion of the deflection yoke and selectively assembling the correction magnetic unit.

이하에서 이를 그 실시예와 함께 좀더 상세히 설명하면 다음과 같다.It will be described below in more detail with the embodiment as follows.

즉, 제3도는 본 고안에 의한 편향요크(1)를 나타내었다.That is, FIG. 3 shows the deflection yoke 1 according to the present invention.

여기서는 편향요크(1)의 장구경방향플랜지(13)의 외곽 원주면을 따라 라인홈(11)을 삭설하고 이에는 보정자성 유니트(12)를 선택적으로 조립맞춤 가능케된 구성으로 되어있다.Here, the line groove 11 is cut along the outer circumferential surface of the long diameter flange 13 of the deflection yoke 1, and the correction magnetic unit 12 is configured to be selectively assembled and fitted.

또, 상기 보정자성 유니트(12)는 제4도 (a)와 같이 장방쐐기(12a) 또는 원추쐐기(12b) 형태로 구성할 수 있다.In addition, the correction magnetic unit 12 may be configured in the form of a rectangular wedge 12a or a cone wedge 12b as shown in FIG.

또, 상기 장방쐐기(12a)는 또는 원추쐐기(12b)는 상기 라인홈(11)에 조립맞춤 가능한 어떠한 유형도 만족할수 있음을 알수있다.Further, it can be seen that the rectangular wedge 12a or the conical wedge 12b can satisfy any type that can be assembled to the line groove 11.

또, 상기 라인홈(11)측의 보정자성 유니트(12)는 그 자체 수평폭 길이가 1cm정도로, 3-5cm 간격으로 설치하면 바람직하다.In addition, it is preferable that the correction magnetic unit 12 on the side of the line groove 11 has its own horizontal width of about 1 cm and is provided at intervals of 3-5 cm.

이러한 구성의 본 고안은 그 작용 및 효과는 다음과 같다.The present invention of this configuration is as follows.

즉, 본고안의 편향요크(1)로 미스컨버젼스를 조정할때는 제4도 (a) 및 (b)의 같은 보정자성 유니트로 라인홈(11)에 선택적으로 끼워 넣으므로서 미스컨버젼스를 조정할수 있다.That is, when adjusting the misconvergence with the deflection yoke 1 of this paper, it is possible to adjust the misconvergence by selectively inserting it into the line groove 11 with the same correction magnetic unit shown in Figs. 4A and 4B.

이때 보정자성 유니트(12)는 편향요크측의 투과율과 위치에 따라 조정양이 달라지므로서 그 컨버젼스 조정이 가능케 되는 것이다.At this time, the correction magnetic unit 12 is capable of adjusting the convergence because the amount of adjustment varies depending on the transmittance and the position of the deflection yoke side.

이러한 본 고안은 편향요크측의 플랜지부위에 미스컨버젼스의 보정자성 유니트를 선택적으로 끼워맞춤 가능한 조립구조를 두므로서 이러한 물품의 미스컨버젼스 조정을 이룰수 있고 고품위 화질의 칼라수상관 제작이 가능케 되는 유익한 특징이 있는 것이다.The present invention provides an assembly structure capable of selectively fitting a mis-convergence correction magnetic unit on the flange side of the deflection yoke, which makes it possible to achieve misconvergence adjustment of the article and to produce a high-quality color water pipe. Is there.
