본 발명은 편향요크의 VCR 개선용 네크암에 관한 것으로서 편향요크의 네크부에 결합시켜 XH 또는 YH 등의 편향특성을 보정하기 위한 네크암을 네크부 상면에 체결 결합하여 편향용크의 편향특성에 대한 보정을 용이하게 수행할 수 있도록 한 편향요크의 VCR 개선용 네크암에 관한 것이다.The present invention relates to a neck arm for improving the VCR of the deflection yoke, and is coupled to the neck portion of the deflection yoke, and the neck arm for correcting deflection characteristics such as XH or YH is coupled to the upper surface of the neck portion for deflection characteristics of the deflection yoke. The present invention relates to a neck arm for improving the VCR of a deflection yoke so that correction can be easily performed.

일반적으로 편향요크는 음극선관의 외주에 장착되어 음극선관의 전자총으로부터 발사되는 전자빔을 편향시켜 정확도 있는 화상을 구현되게 한다.In general, the deflection yoke is mounted on the outer circumference of the cathode ray tube so as to deflect the electron beam emitted from the electron gun of the cathode ray tube to realize an accurate image.

이러한, 편향요크는 음극선관으로부터 발사되는 전자빔을 수직방향으로 편향시키는 수직편향코일과, 전자빔을 수직방향으로 편향시키는 수직편향코일과, 전자빔을 수평방향으로 편향시키는 수평방향코일과, 상기 수직편향코일의 위치를 정밀도 있게 구분함과 동시에 상호 전기적으로 절연될 수 있도록 하는 세퍼레이터로 구성된다.Such a deflection yoke includes a vertical deflection coil for deflecting an electron beam emitted from a cathode ray tube in a vertical direction, a vertical deflection coil deflecting an electron beam in a vertical direction, a horizontal coil deflecting an electron beam in a horizontal direction, and the vertical deflection coil. It is composed of a separator that can precisely classify the positions of and to be electrically insulated from each other.

이때, 음극선관의 전자총에서 발사되는 R(RED), G(GREEN), B(BLUE)의 전자빔은 상기 편향요크에 의하여 소정 각도로 편향된 후 섀도우마스크에 형성된 관통공을 통과하고 패널(PANEL)의 내주에 장착된 형광면 각각의 스트라이프(stripe)에 봉착하여 발광함으로써 텔레비젼의 스크린에 정상적인 화상을 구현하게 된다.At this time, the electron beams of R (RED), G (GREEN), and B (BLUE) emitted from the electron gun of the cathode ray tube are deflected at a predetermined angle by the deflection yoke, and then pass through the through holes formed in the shadow mask, and the panel (PANEL) By sealing the light on each stripe mounted on the inner circumference and emitting light, a normal image is realized on the screen of the television.

한편, 상기 세퍼레이터의 내주연에 장착되는 수평편향코일은 그 장착된 상태또는 권회된 형상에 따라 편향각도의 차이를 발생할 수 있는데, 편향각도가 어긋나 화면상에 역크로스 및 미스컨버젼스를 초래함으로써 정상적인 화상의 구현을 어렵게 만드는 경우도 있다.On the other hand, the horizontal deflection coil mounted on the inner circumference of the separator may cause a difference in the deflection angle depending on the mounted state or the wound shape. The deflection angle is displaced, resulting in reverse crossover and misconvergence on the screen. It can also make implementation difficult.

이러한, 경우 페라이트(ferrite) 재질의 네크암을 사용하여 역크로스 및 미스컨버전스 등 편향특성을 보정하게 되는데, 상기 네크암은 화면의 X축 또는 Y축 상에 나타나는 화면상의 수평편향코일의 수평 자계(XH,YH)에 패턴변화를 주어 편향특성을 보정하여준다.In this case, the deflection characteristics such as reverse cross and misconvergence are corrected by using a ferrite neck arm, which is a horizontal magnetic field of the horizontal deflection coil on the screen which appears on the X or Y axis of the screen. XH, YH) gives a pattern change to correct deflection characteristics.

나아가, 상기 네크암은 세페레이터의 네크부 상면에 형성된 네크암 고정구조 내에 고정된다.Further, the neck arm is fixed in the neck arm fixing structure formed on the upper surface of the neck portion of the separator.

그런데, 종래기술에 의하면 네크암을 고정하기 위한 고정구조가 일정한 틀로 형성되어 있고 그 내에 네크암의 위치/고정되는 구조이므로 네크암의 고정위치에 대한 적절한 변동이 불가능하게 되는 단점이 있었으며 이에 따라 편향특성의 조절이 용이하지 못하게 되는 문제점이 있었다.However, according to the related art, since the fixing structure for fixing the neck arm is formed in a predetermined frame and the position / fixing structure of the neck arm is located therein, there is a disadvantage in that proper fluctuation of the fixing position of the neck arm is impossible. There was a problem that the adjustment of the property is not easy.

따라서 본 발명의 주 목적은 편향요크의 네크부에 탈착방식으로 네크암을 결합하되 네크부의 상면과 외주연에 밀착되도록 결합하여 편향요크의 VCR 특성 보정을 개선시킬 수 있도록 하는 편향요크의 VCR 특성 개선용 네크암을 제공하는데 있다.Therefore, the main object of the present invention is to improve the VCR characteristics of the deflection yoke to improve the VCR characteristics correction of the deflection yoke by coupling the neck arm to the neck portion of the deflection yoke in a detachable manner but close to the upper surface and the outer periphery of the neck portion. It is to provide dragon neck cancer.

위와 같은 목적을 달성하기 위하여 본 발명의 편향요크의 VCR특성 개선용 네 크암은 편향요크의 네크부에 결합하여 VCR 특성을 개선하는 네크암에 있어서, In order to achieve the above object, the neck arm for improving the VCR characteristics of the deflection yoke of the present invention is coupled to the neck portion of the deflection yoke in the neck arm for improving the VCR characteristics.

The inner portion 112b cut to be formed is formed so as to be bent in the horizontal direction so as to be hooked to the lower end of the side of the neck 111.

또한, 상기 네크암(112)은 네크부(111)의 외주연에 밀착될 수 있도록 밀착부(112a,112a')를 만곡시켜 수직방향으로 직립되게 형성시키되 상호 일정간격으로 이격되도록 수평방향으로 절곡된 부위에 내입부(112a)를 형성시켜 밀착부에 탄력성을 부여하도록 함으로서 네크부에 결합시 보다 탄력적으로 네크부의 외주연에 밀착부(112a,112a')가 결합될 수 있도록 한다.In addition, the neck arm 112 is bent in the horizontal direction so as to be perpendicular to the vertical direction by bending the contact portion (112a, 112a ') so as to be in close contact with the outer periphery of the neck portion 111. By forming the inner portion (112a) in the portion so as to give elasticity to the close contact portion to be coupled to the neck portion 112a, 112a 'to the outer periphery of the neck more elastically when combined.

더불어, 걸림부(112c)는 내입부와 일정간격으로 이격되어 일측을 절곡시키고 타측은 개방시켜 자체 탄성을 갖도록 부여하여 네크암을 네크부의 일측단턱에 결합시킬 때 탄력적으로 손쉽게 결합될 수 있도록 한다.In addition, the engaging portion (112c) is spaced at a predetermined interval with the inner portion is bent one side and the other side is open to give it has its own elasticity so that it can be easily elastically coupled when the neck arm is coupled to one side of the neck portion.

위와 같이 구성된 본 발명의 바람직한 실시예를 첨부한 도면을 참조하면서 보다 상세히 설명하면 다음과 같다. When described in more detail with reference to the accompanying drawings, preferred embodiments of the present invention configured as described above are as follows.

도 2 또는 도 3에서 도시한 바와 같이, 본 발명의 편향요크의 VCR 특성 개선용 네크암은 편향요크(100)의 네크부(111)에 결합하여 VCR 특성을 개선하는 네크암(112)에 있어서,2 or 3, the neck arm for improving the VCR characteristics of the deflection yoke of the present invention is coupled to the neck portion 111 of the deflection yoke 100 in the neck arm 112 for improving the VCR characteristics. ,

상기 네크암(112)은 네크부(111)의 외주연에 밀착 가능하게 만곡시킨 밀착부(112a,112a')를 형성시키고 그 중앙으로 상기 밀착부(112a,112a')를 상호 일정간격으로 유격되도록 절개된 내입부(112b)를 형성시키되 상기 네크부(111)의 측면 하단에 상호 걸릴 수 있도록 수평방향으로 걸림부(112c)를 절곡시켜 구성한다.The neck arm 112 forms contact portions 112a and 112a 'which are curved to be in close contact with the outer circumference of the neck portion 111, and the contact portions 112a and 112a' are spaced apart from each other at regular intervals. The inner portion 112b cut to be formed is formed so as to be bent in the horizontal direction so as to be hooked to the lower end of the side of the neck 111.

이렇게 구성된 네크암(112)은 편향요크(100)의 네크부(111) 양측에 대칭되게 각각 결합시키되 먼저, 걸림부(112c)를 편향요크(100)의 네크부(111) 하단에 걸리도록 한 다음 네크암(112)의 일측단을 네크부(111) 측으로 가압하면 걸림부(112c)는 자체 탄성에 의해 벌어지면서 밀착부(112a)가 네크부(111)의 외주연에 밀착된다.The neck arm 112 configured as described above is symmetrically coupled to both sides of the neck portion 111 of the deflection yoke 100, but first, the catching portion 112c is hung on the lower end of the neck portion 111 of the deflection yoke 100. Next, when one side end of the neck arm 112 is pressed toward the neck portion 111 side, the locking portion 112c is opened by its elasticity, and the contact portion 112a is in close contact with the outer circumference of the neck portion 111.

이때, 밀착부(112a) 또한 절개된 내입부(112b)에 의해 자체 탄력성이 부여되어 있으므로서 네크부(111)의 외주연에 밀착부(112a,112a')가 긴밀하게 밀착되게 결합하여 편향특성(XH,YH)에 대한 특성보정을 용이하게 할 수 있는 효과가 있다.At this time, since the close contact portion 112a is also provided with its own elasticity by the cut-in indentation 112b, the close contact portion 112a and 112a 'are closely coupled to the outer periphery of the neck 111 so that the deflection characteristics There is an effect of facilitating the characteristic correction for (XH, YH).

이상에서 살펴본 바와 같이, 편향요크의 네크부에 탈착방식으로 네크암을 결합하되 네크부의 상면과 외주연에 밀착되도록 결합하여 편향요크의 VCR 특성 보정을 개선시킬 수 있도록 하는 효과가 있다.












As described above, the neck arm is coupled to the neck portion of the deflection yoke in a detachable manner, but the neck arm is coupled to be in close contact with the upper surface and the outer periphery of the neck portion, thereby improving the VCR characteristic correction of the deflection yoke.
