편향요크의 폴 마그네트 지지구조{Support structure for pole magnet of deflection yoke}Support structure for pole magnet of deflection yoke

본 발명은 편향요크의 폴 마그네트 지지구조에 관한 것으로, 더욱 상세하게는 폴 마그네트를 지지하는 네크에 외부의 영향력이 작용하더라도 폴 마그네트의 안정된 지지를 유지하도록 하여 컨버전스의 조정을 용이하게 할 수 있도록 한 편향요크의 폴 마그네트 지지구조에 관한 것이다.The present invention relates to a pole magnet support structure of a deflection yoke, and more particularly, to maintain a stable support of a pole magnet even when an external influence is applied to the neck supporting the pole magnet to facilitate adjustment of convergence. It relates to a pole magnet support structure of a deflection yoke.

일반적으로 편향요크는 음극선관의 전자총으로부터 발사되는 전자빔을 편향시키는 장치로서 도 1에 나타낸 바와 같이, 전자빔을 수평방향으로 편향시키는 수평편향코일(미 도시됨)과, 전자빔을 수직방향으로 편향시키는 수직편향코일(24)과, 두 편향코일의 위치를 정밀도 있게 구분함과 동시에 상호 전기적으로 절연될 수 있도록 하는 세퍼레이터(20)로 구성된다.Generally, a deflection yoke is a device for deflecting an electron beam emitted from an electron gun of a cathode ray tube, as shown in FIG. 1, a horizontal deflection coil (not shown) for deflecting an electron beam in a horizontal direction, and a vertical deflection for deflecting an electron beam in a vertical direction. A deflection coil 24 and a separator 20 for precisely distinguishing the positions of the two deflection coils and being electrically insulated from each other.

이때, 상기 음극선관의 전자총에서 발사되는 R(Red), G(Green), B(Blue)의 전자빔은 편향요크(10)에 의하여 소정 각도로 편향되어 섀도우마스크에 형성된 관통공을 통과해서 패널(panel)의 내주에 장착된 형광면 각각의 스트라이프(stripe)에 봉착하여 발광함으로써 텔레비젼의 스크린에 정상적인 화상을 구현한다.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 10 and pass through the through-holes formed in the shadow mask to make the panel ( A normal image is realized on the screen of a television by sealing a stripe of each of the fluorescent surfaces mounted on the inner circumference of the panel and emitting light.

이와 같이 음극선관의 전자총에서 발사되는 전자빔을 소정 각도로 편향시키는 기능을 수행하는 수평편향코일(미 도시됨) 및 수직편향코일(24)은 세퍼레이터(20)의 내·외주연에 장착된 상태 또는 권회된 형상에 따라 편향각도가 어긋나 전자빔의 미스랜딩 및 미스컨버전스 등을 초래하여 정상적인 화상을 구현하지 못하는 경우가 발생되기도 하는데, 이러한 경우 통상적으로 퓨리티 자석 또는 컨버전스 자석이라 불리는 폴 마그네트(30)로 자계에 변화를 줌으로써 컨버전스를 조정하여 양질의 화면을 제공하게 된다.As such, the horizontal deflection coil (not shown) and the vertical deflection coil 24, which perform the function of deflecting the electron beam emitted from the electron gun of the cathode ray tube at a predetermined angle, are mounted on the inner and outer circumferences of the separator 20 or Depending on the wound shape, the deflection angle is shifted, which may result in mis-landing and misconvergence of the electron beam, thereby failing to realize a normal image. By changing the convergence, the convergence is adjusted to provide a good picture.

한편, 상기 기능을 수행하는 폴 마그네트(30)는 네크(23)에 장착될 수 있도록 원형의 링타입으로 성형되어 이루어지고, 상기 네크(23)는 세퍼레이터(20)의 네크부(21) 상면에 일체로 얇고 일정한 두께로 형성되어 폴 마그네트(30)를 지지할 수 있는 구조로 이루어진다.On the other hand, the pole magnet 30 performing the function is made of a circular ring type to be mounted on the neck 23, the neck 23 is formed on the upper surface of the neck portion 21 of the separator (20) It is integrally formed in a thin and constant thickness is made of a structure capable of supporting the pole magnet 30.

그런데, 종래 기술에 따른 편향요크(10)의 폴 마그네트 지지구조는 상기 폴 마그네트(30)를 지지하는 네크(23)의 두께가 얇아 네크밴드의 체결 등 외부의 영향력에 쉽게 찌그러지는 현상이 발생하여 폴 마그네트(30)의 지지상태가 해제되어 유동이 발생하게 됨으로써 미스랜딩 및 미스컨버전스 조정이 용이하지 못하여 품질의 안정성이 저하되는 문제점이 있었다.By the way, the pole magnet support structure of the deflection yoke 10 according to the prior art has a thin thickness of the neck 23 supporting the pole magnet 30 is easily crushed by external influences such as fastening the neck band. Since the support state of the pole magnet 30 is released and the flow is generated, mislanding and misconvergence adjustment is not easy, and thus there is a problem in that stability of quality is deteriorated.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적으로 하는 바는 폴 마그네트를 지지하는 네크의 하부 두께를 확대 성형하여 네크의 상부보다 더 두꺼운 두께를 갖도록 한 폴 마그네트 지지구조를 제공함으로써 외부의 영향력이 작용하더라도 쉽게 찌그러지지 않고 폴 마그네트를 안정되게 지지되도록 하여 폴 마그네트의 미스랜딩 및 미스컨버전스 조정이 용이하도록 하므로 품질의 안정성을 향상시킬 수 있도록 하는데 있다.Therefore, the present invention has been proposed to solve the above problems, and its purpose is to extend the bottom thickness of the neck supporting the pole magnet by forming a pole magnet support structure to have a thickness thicker than the top of the neck. By providing a pole magnet that can be stably supported without being easily distorted even when an external influence is applied, it is possible to improve mis-landing and misconvergence adjustment of the pole magnet, thereby improving quality stability.

Forming to have a thickness thicker than the upper is a basic feature of the technical configuration.

위와 같이 구성된 본 발명의 바람직한 실시예를 도면을 참조하면서 상세히 설명하면 다음과 같다.Referring to the preferred embodiment of the present invention configured as described above in detail with reference to the drawings as follows.

도 2는 본 발명에 따른 편향요크의 폴 마그네트 지지구조를 나타낸 사시도이고, 종래와 동일 작용을 하는 동일 구성에 대해서는 동일 명칭 및 동일 부호를 병기 사용하기로 한다.Figure 2 is a perspective view showing a pole magnet support structure of the deflection yoke according to the present invention, and the same name and the same reference numerals will be used for the same configuration having the same function as the conventional.

도 2에 나타낸 바와 같이, 본 발명에 따른 편향요크(10)의 폴 마그네트 지지구조는 전자빔을 수평방향으로 편향시키는 수평편향코일(미 도시됨)과, 전자빔을 수직방향으로 편향시키는 수직편향코일(24)과, 수직편향코일(24) 및 수평편향코일(미 도시됨)의 위치를 정밀도 있게 구분함과 동시에 상호 전기적으로 절연될 수 있도록 하는 세퍼레이터(20)로 구성된다.As shown in FIG. 2, the pole magnet supporting structure of the deflection yoke 10 according to the present invention includes a horizontal deflection coil (not shown) for deflecting the electron beam in the horizontal direction, and a vertical deflection coil for deflecting the electron beam in the vertical direction ( 24) and a separator 20 for precisely classifying the positions of the vertical deflection coil 24 and the horizontal deflection coil (not shown) and electrically insulating each other.

상기 세퍼레이터(20)는 네크부(21)와 플랜지부(22)로 이루어지며, 상기 네크부(21)의 상면에는 직립상태의 원형으로 성형되어 폴 마그네트(30)를 끼움 결합하고 지지하는 네크(50)가 일체로 형성된다.The separator 20 is composed of a neck portion 21 and a flange portion 22, the neck portion 21 is formed in a circular shape of an upright state on the upper surface of the neck portion 21 to fit and support the pole magnet 30 ( 50) is integrally formed.

이때, 상기 네크(50)는 하부의 두께를 확대 성형하여 상부보다 더 두꺼운 두께를 갖도록 형성된다.At this time, the neck 50 is formed to have a thickness thicker than the upper portion by expanding the thickness of the lower portion.

이와 같이 구성된 본 발명에 따른 편향요크(10)의 폴 마그네트 지지구조의 지지동작을 설명하면 다음과 같다.Referring to the supporting operation of the pole magnet support structure of the deflection yoke 10 according to the present invention configured as described above are as follows.

폴 마그네트(30)를 파지하여 세퍼레이터(20)의 네크부(21) 상면에 형성된 네크(50)에 끼워 가압하면 두께가 확대 성형된 네크(50)의 하부 외주연에 밀착되어 지지됨으로써 폴 마그네트(30)의 고정을 완료하게 되고, 네크밴드의 체결 등 외부의 영향력이 네크(50)에 작용하더라도 두텁게 형성된 네크(50) 하부의 폴 마그네트(30) 지지구조에 의해 폴 마그네트의 안정된 지지를 유지하게 되어 미스랜딩 및 미스컨버전스 등을 초래할 경우 이에 능동적으로 대응하여 폴 마그네트를 좌·우 방향으로 움직임으로써 전자빔의 궤도를 효과적으로 조정하게 된다.When the pole magnet 30 is gripped and pressed to the neck 50 formed on the neck 21 of the separator 20, the pole magnet 30 is held in close contact with the lower outer periphery of the enlarged neck 50, thereby supporting the pole magnet ( 30) is completed, and even if an external influence such as fastening of the neck band acts on the neck 50, the pole magnet 30 supporting structure under the thick neck 50 is formed to maintain stable support of the pole magnet. Therefore, in case of mis-landing and mis-convergence, the trajectory of the electron beam is effectively adjusted by moving the pole magnet in the left and right directions in response to this.

이상에서 살펴본 바와 같이 본 발명에 따른 편향요크의 폴 마그네트 지지구조에 의하면, 폴 마그네트를 지지하는 네크의 하부에 확대 성형시킨 네크 두께를 제공하여 폴 마그네트를 지지하게 함으로써 네크밴드의 체결 등 외부의 영향력이 작용하더라도 쉽게 찌그러지지 않고 폴 마그네트를 안정되게 지지하여 미스랜딩 및 미스컨버전스 조정을 용이하도록 하므로 품질의 안정성을 향상시키는 효과가 있다.As described above, according to the pole magnet support structure of the deflection yoke according to the present invention, by providing an enlarged neck thickness formed on the lower part of the neck supporting the pole magnet to support the pole magnet, external influence such as fastening the neck band Even if this action is not easily crushed, the pole magnet is stably supported to facilitate mis-landing and mis-convergence adjustment, thereby improving quality stability.
