본 고안은 음극선관용 편향요크 보정장치에 관한 것으로 보다 상세하게는 새들타입의 편향코일의 내면에 보정용 기구를 삽입하여 미스컨버젼스를 보정하는 것에 관한 것이다.The present invention relates to a deflection yoke correction device for cathode ray tubes, and more particularly, to correct misconvergence by inserting a correction mechanism into an inner surface of a saddle type deflection coil.

통상 음극선관은 판넬과 네크사이에 편향요크를 장착하여 수평출력회로와 수직 출력회로로부터 신호전류를 공급받아 자력선을 방출시켜 플레밍의 왼손법칙에 의해 전자총에서 방출되는 전자빔을 편향시켜서 판넬내면에 형성되어 있는 형광체에 충돌케 함으로서 형광면에 화상을 형성하게 된다.The cathode ray tube is generally formed inside the panel by deflecting the electron beam emitted from the electron gun by Fleming's left-hand law by mounting a deflection yoke between the panel and the neck and receiving signal current from the horizontal and vertical output circuits. By colliding with a fluorescent substance, an image is formed on the fluorescent surface.

제1도에서, 편향요크(10)는 일반적으로 수평편향코일(20) 및 수직편향코일(30)을 주요 요소로 하고 이들은 코어(core)와 보빈(bobbin)에 의해 결합되며, 상기 수평편향코일(20) 및 수직편향코일(30)은 새들(saddle)형 편향코일과, 트로이달(torroidal)형 편향코일로 크게 분류되는데, 새들형 편향코일은 말안장 모양을 한 형태로 2개 1조로서 2조가 서로 마주보게 되며, 트로이달 코일은 편향요크(10)의 외측에 형성된 코어(40)에 직접 코일을 권회시켜 새들형 편향코일과 서로 직각이 되도록 조립된 구조로 되어 있다.In FIG. 1, the deflection yoke 10 generally has a horizontal deflection coil 20 and a vertical deflection coil 30 as main elements, which are coupled by a core and bobbin, and the horizontal deflection coils. 20 and vertical deflection coils 30 are classified into saddle-type deflection coils and toroidal deflection coils, and saddle-shaped deflection coils are saddle-shaped in two sets. The two pairs face each other, and the troidal coil has a structure assembled so as to be perpendicular to the saddle-type deflection coil by winding the coil directly on the core 40 formed on the outside of the deflection yoke 10.

이러한 구조로 이루어진 편향요크(10)는 통상 음극선관의 다관종에 따라 유동적으로 병행하여 사용되고 있으며, 상기 편향요크(10)의 자계분포는 일반적으로 핀쿠션자계(실패형자계)를 형성시킨다.The deflection yoke 10 having such a structure is usually used in parallel in accordance with the multiple tube type of the cathode ray tube, and the magnetic field distribution of the deflection yoke 10 generally forms a pincushion magnetic field (failure type magnetic field).

그런데 상술한 핀쿠션자계는 편향중심에서 형광면의 거리가 주변으로 갈수록 길게 되기 때문에 컨버젼스가 미끄러져 기준위치에서 벗어나게 되며, 특히 전자빔중 청색빔이나 적색빔쪽의 자계가 중앙의 녹색빔에 비해 강하게 또는 약하게 미치는 현상이 나타난다. 따라서 자계분포의 중앙위치점에 가까운 빔은 덜 편향되고, 먼 빔일수록 더욱 강한 자계의 힘을 받기 때문에 결과적으로 스크린의 주변부는 미스컨버젼스가 발생된다.However, in the pincushion magnetic field described above, since the distance of the fluorescent surface becomes longer toward the periphery of the deflection center, the convergence slips out of the reference position. The phenomenon appears. Therefore, the beam closer to the center position of the magnetic field distribution is less deflected, and the farther beam receives the stronger magnetic force, resulting in misconvergence at the periphery of the screen.

따라서 이러한 미스컨버젼스 현상을 줄이고자 여러가지 방법이 제시되었으며, 예컨데 편향코일에 인가시키는 회로를 변화시키거나, 전자총의 컨버젼스 컵내부에 차폐(Shunt)와 강조(Enhancer)라고 칭하는 내부 자성체를 붙여서 그러한 현상을 보정하고 있었다.Therefore, various methods have been proposed to reduce such misconvergence phenomena, for example, by changing the circuit applied to the deflection coil or by attaching an internal magnetic material called shunt and enhancer inside the convergence cup of the electron gun. I was correcting.

그러나 종래 기술에는 회로적으로나 전자총의 내부에 보정기구를 설치하는 것이 결과적으로 음극선관이 완성된 이후에 최종공정인 ITC(integrated tube component)공정에서 편향요크와 PCM(purity convergence magnet)후에 발생되는 상기 미스컨버젼스를 해결해 주지 못하였다.However, in the prior art, the provision of a calibrating mechanism in the circuitry or inside of the electron gun results in the deflection yoke and the PCM (purity convergence magnet) in the final tube ITC process after the cathode ray tube is completed. It did not solve the misconvergence.

또한 종래에는 보정철편을 편향코일의 내면에 부착시켜 보정하였으나 이 같은 방법도 음극선관의 관종마다 또는 같은 관종이라도 편향요크의 제품마다 각기 다른 특성을 갖고 있기 때문에, 상기 보정철편을 부착시키는 위치가 각기 달라 숙련된 작업자도 상당한 시간이 필요하였다.In addition, in the prior art, the correction iron piece was attached to the inner surface of the deflection coil, and the correction was made. However, this method has different characteristics for each tube type of the cathode ray tube or the same type of deflection yoke. Each skilled worker also required considerable time.

본 고안은 상술한 제반문제를 해결하고자 안출한 것으로, 그 목적은 편향요크의 새들형 편향코일에서 편향된 전자빔의 스크린 주변부에 미스컨버젼스를 보상하는 장치를 제공하려는 것이다.The present invention has been made to solve the above-mentioned problems, and its object is to provide an apparatus for compensating misconvergence in the periphery of the screen of the electron beam deflected in the saddle-shaped deflection coil of the deflection yoke.

이와 같은 목적을 달성하기 위하여 본 고안은 양분된 보빈의 상하에 마주보게 결합시키는 새들형 편향코일에 있어서, 상기 결합된 새들형 편향코일의 상하부 보빈사이에 절연비닐편을 부착시켜 미스컨버젼스를 보상시키는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a saddle-shaped deflection coil coupled to face up and down of a nutrient bobbin, and attaches an insulating vinyl piece between upper and lower bobbins of the saddle-shaped deflection coil to compensate for misconvergence. It is characterized by.

이하 본 고안의 바람직한 일 실시예를 기준으로 상세하게 설명한다.Hereinafter will be described in detail with reference to a preferred embodiment of the present invention.

도시된 제2도는 본 고안에 따라 보빈(60)의 일측에 절연비닐편(80)을 부착시킨 개략적인 사시도이며, 제3도는 제2도를 확대도시한 평면도이고, 제3(a)도는 본 고안의 요부와 그 작용상태를 보인 예시도이다.FIG. 2 is a schematic perspective view of the insulating vinyl piece 80 attached to one side of the bobbin 60 according to the present invention, and FIG. 3 is an enlarged plan view of FIG. 2 and FIG. Exemplary diagram showing the main part and the working state of the invention.

제2도 및 제3도에서 보듯이, 네크삽입부(15)를 중심으로 좌우측으로 미세하게 분리이격되어 설치된 한 쌍의 수평편향코일(20)과 이 수평편향코일(20)을 양쪽으로 분리시켜주는 보빈(60)과 상기 보빈(60)의 일측에 절연비닐편(80)이 부착된 구조인 것이다.As shown in FIG. 2 and FIG. 3, the pair of horizontal deflection coils 20 and the horizontal deflection coils 20 are separated from both sides by finely separating the left and right sides of the neck insertion unit 15 from each other. The main bobbin 60 and the insulating vinyl piece 80 is attached to one side of the bobbin 60 is a structure.

이렇게 이루어진 본 고안의 작용 및 효과를 살펴보면, 새들형 편향코일의 자계 분포상 상하 코일의 인접된 부위에서 자계 형상이 전자빔에 영향을 줄 수 없을 정도로 자계반경이 매우 작은 형상으로 나타나기 때문에 본 고안에 따라 부착된 절연비닐편(80)을 새들형 편향코일의 인접된 부위의 보빈에 부착함으로서 상기 편향자계 반경을 확대 변경시킬 수 있어, 스크린 주변부에서 발생되는 미스컨버젼스 현상을 최소화 할 수 있는 것이다.Looking at the operation and effect of the present invention made in this way, because the magnetic field radius in the adjacent portion of the upper and lower coils in the magnetic field distribution of the saddle-type deflection coil appears so small that the magnetic field radius does not affect the electron beam is attached according to the present invention By attaching the insulating vinyl piece 80 to the bobbins of adjacent portions of the saddle-type deflection coil, the deflection field radius can be enlarged and changed, thereby minimizing misconvergence occurring at the periphery of the screen.

이상에서 살펴본 바와 같이, 본 고안에 따라 부착된 절연비닐편은 여러가지 회로변경이나 기구적인 특성변화 없이도 컨버젼스를 보정할 수 있는 효과가 있으며, 아울러 숙력된 작업자가 아니더라도 충분히 이러한 작업을 수월하게 진행할 수 있는 것이다.As described above, the insulating vinyl piece attached according to the present invention has the effect of correcting the convergence without various circuit changes or mechanical characteristic changes, and it is possible to easily perform such a task easily even without a skilled worker. will be.
