* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 세퍼레이터 2 : 보정코일1: Separator 2: Correction coil
2a : 철심 2b : 동선2a: iron core 2b: copper wire
3 : 수직코일3: vertical coil
본 고안은 편향요크의 설계오차 또는 조립오차에 기인하는 미스 컨버어젼스를 용이하게 수정할 수 있게 한 편향요크에 관한 것이다.The present invention relates to a deflection yoke that enables easy correction of miss convergence due to a design or assembly error of a deflection yoke.
편향요크는 음극선관의 넥크 전방에 장착되어서, 전자총으로 부터 발진되는 비임을 편향시켜 화면의 모서리 부분에 까지 주사되게 하는 부품으로써, 그 주된 구조는 나팔모양의 세퍼레이터 외측에 비임의 상하방향성분을 편향시키는 수직코일이 부착되고, 내측으로 비임의 좌우방향성분을 편향시키는 수평코일이 부착되어 이루어진다.The deflection yoke is mounted in front of the neck of the cathode ray tube, and deflects the beam oscillated from the electron gun to be scanned to the edge of the screen.The main structure of the deflection yoke deflects the beam's up and down components outside the trumpet-shaped separator. A vertical coil is attached, and a horizontal coil is attached to deflect the left and right components of the beam inward.
이들 양 코일은 통전 시 비임 통로 상에 자계가 형성되게 하여, 이 자계에 의해 비임이 편향되게 하는 것인바, 이러한 편향요크에 의해 나타나는 컨버어젼스 정확도는 제1도에 도시한 바와 같이 화면의 X축 중심선 C에 나타나는 G비임을 기준으로 하여 판단된다.Both coils cause a magnetic field to form on the beam path during energization, which causes the beam to deflect by this magnetic field. The convergence accuracy exhibited by this deflection yoke is shown in FIG. Judgment is made based on the G beam appearing at the center line C of the axis.
즉, 이 G비임을 축으로하여 양측의 R, B비임이 합치될 때 정확한 컨버어젼스를 이루는 것으로 판정한다.In other words, it is determined that an accurate convergence is achieved when the R and B beams on both sides coincide with this G beam as an axis.
그런데, 제조공정에서 편향요크가 음극선관에 장치된 후에는 설계 의도와 달리 전자비임의 컨버어젼스상태가 예상과 달리 나타나는 일이 빈번하다.However, after the deflection yoke is installed in the cathode ray tube in the manufacturing process, the convergence state of the electron beam is often different from what is expected, unlike the design intention.
흔히 나타나는 현상으로는 도시한 바와 같이 R, B비임이 중앙의 G비임에 대하여 만곡지게 컨버어젼스되는 것을 들 수 있다.A common phenomenon is that the R and B beams are curved converging with respect to the center G beam as shown.
이러한 미스 컨버어젼스는 자석이나 철편등을 세퍼레이터 혹은 수직코일 사이에 개재시켜 자계범위를 보정하는 방법으로 수정하여 왔으나, 이러한 수정방법은 시간이 많이 걸리고 또 일률적이 못한 것이므로 제품의 질이 불균일하게 되는 문제와 작업성이 좋지 않은 단점을 안고 있다.This miss convergence has been modified by calibrating the magnetic field range by interposing a magnet or a piece of iron between separators or vertical coils. However, this correction method is time consuming and uneven, resulting in uneven product quality. It has the disadvantage of poor workability.
본 고안의 목적은 종래의 철편이나 자석을 부착하는 방법을 개선하여 수직코일의 전류파를 제어함으로써 미스 컨버어젼스를 수정할 수 있는 편향요크를 제공함에 있다.An object of the present invention is to provide a deflection yoke capable of correcting miss convergence by controlling a current wave of a vertical coil by improving a conventional method of attaching iron pieces or magnets.
상기 목적에 따라 본 고안은 철심의 외주에 동선을 감아 형성되는 보정코일을 세퍼레이터의 외주에 고정부착하고, 그 위로 수직코일을 부착시킨 구성을 특징으로 한다.According to the above object, the present invention is characterized in that the correction coil formed by winding copper wire around the outer circumference of the iron core is fixedly attached to the outer circumference of the separator, and a vertical coil is attached thereon.
이하, 본 고안을 첨부도면 제2도 내지 제3도를 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to FIGS. 2 to 3.
본 고안은 제2도에 도시한 바와 같이, 세퍼레이터(1)의 외주면 소정위치에 보정코일(1)이 고정 부착되고, 그 위로 통상의 수직코일(3)이 접착 고정된 구성으로 되어 이TEk.According to the present invention, as shown in FIG. 2, the correction coil 1 is fixedly attached to a predetermined position on the outer circumferential surface of the separator 1, and the normal vertical coil 3 is adhesively fixed thereon.
보정코일(2)는 철심(2a)의 외주에 동선(2b)를 감아 붙여 된 것으로서, 상기한 동선(2b)의 양단에는 별도의 컨버어젼스 보정회로로 부터 공급되는 전류를 인가받게 되어 있다.The correction coil 2 is formed by winding a copper wire 2b around the outer periphery of the iron core 2a, and receives current supplied from a separate convergence correction circuit at both ends of the copper wire 2b.
제3도는 본 고안에 적합한 컨버어젼스 보정회로의 일예를 도시하는 회로도로서, 옐로우단자(Y)와 그린단자(G) 사이에 병렬접속된 수직코일(3)의 한쪽 단에는 브리지를 이루는 4개의 다이오드(D1-D4)가 개재되어 있고, 이들 다이오드(D1-D4)의 입출력단에 상기한 보정코일(2)의 동선(2b)가 접속되어 있다.3 is a circuit diagram showing an example of a convergence correction circuit suitable for the present invention, and four bridges are formed at one end of the vertical coil 3 connected in parallel between the yellow terminal Y and the green terminal G. The diodes D1-D4 are interposed, and the copper wire 2b of the correction coil 2 described above is connected to the input / output terminals of the diodes D1-D4.
한편, 브리지를 가로 질러 가변저항(VR1)이 개재되어 있고, 또 브리지의 출력단과 보정코일(2) 사이로 가변정항(VR2)가 개재되어 이 회로를 흐르는 전류의 양을 제어할 수 있게 되어 있다.On the other hand, the variable resistor VR1 is interposed across the bridge, and the variable constant VR2 is interposed between the output terminal of the bridge and the correction coil 2 to control the amount of current flowing through this circuit.
상술한 브리지회로는 수직코일(3)에 흐르는 톱니파전류를 전파(電波) 정류하여 보정코일(2)에 파라보라전류가 인가될 수 있게 하는 것이며, 이 보정코일(2)에 흐르는 전류는 가변저항(VR1)(Vr2)에 의해 가감 조절된다.The bridge circuit described above allows the parabolic current to be applied to the correction coil 2 by propagating the sawtooth wave current flowing through the vertical coil 3, and the current flowing through the correction coil 2 is a variable resistor. It is controlled by (VR1) (Vr2).
이상과 같이 구성된 본 고안에 의해 미스 컨버어젼스가 보정되는 과정을 설명하면 다음과 같다.The process of correcting the miss convergence by the present invention configured as described above is as follows.
미스 컨버어젼스형태는 제1도에 예시한 R, G, B비임이 서로 합치되지 않고 벌어져 나타나거나 또는 G비임을 중심으로 R비임과 B비임이 크로스된 형태로 나타난다.The misconvergence form appears in the form of R, G, and B beams illustrated in FIG. 1 not being coincident with each other, or in a form in which the R and B beams are crossed with respect to the G beam.
먼저, 미스 컨버어젼스형태가 벌어져 나타나는 경우에는 가변저항(VR1)을 조작하여 보정하고, 크로스형태의 미스컨버어젼스는 가변저항(VR2)를 조작하여 보정한다.First, when the misconvergence form appears wide, it is corrected by operating the variable resistor VR1, and the cross-type misconvergence is corrected by operating the variable resistor VR2.
상술한 바와 같이 본 고안은 편향요크 자체의 조립 또는 설계오차로 인하여 나타나는 미스컨버어젼스를 보정코일의 자계로 보정하는 것이므로 종래와 같이 철편이나 자석등을 무작위로 위치선정하여 가면서 보정하는 방법에 비하여 한층 간단하고 용이하게 행할 수 있고, 또 보정된 결과는 편향요크마다 일률적으로 나타나는 것이기 때문에 제품의 질을 균일히 할 수 있는 실용성을 갖추고 있다.As described above, the present invention is to compensate for the misconvergence caused by the assembly or design error of the deflection yoke by the magnetic field of the correction coil. It is simpler and easier to perform, and the corrected results are uniformly displayed for each deflection yoke, so that the quality of the product can be made uniform.
