본 고안은 브라운관에 설치사용되는 편향요크의 개선된 클램프부구조에 관한 것이다.The present invention relates to an improved clamp portion structure of a deflection yoke for use in a CRT.

주지된 바와 같이 이러한 브라운관의 편향 요크는 그 편향요크조립체 후부를 브라운관 네크부외주면에 죄어 고정시킬 수 있도록 하기 위한 클램프수단을 구비하게 되는데, 이러한 클램프수단은 보통 브라운관네크부주위를 감싸도록 방사상으로 배치된 수지재 클램프 요소들이 그 외주면에 권착되는 체결밴드에 의해 브라운관 네크부외주면에 밀착고정되어 지도록 되어 있는 바, 종래에는 마찰계수가 작은 상기 수지재의 클램프요소들이 네크부 외면에 미끄럼유동없이 밀착고정되도록 하는 것을 보장하기 위해 먼저 네크부외면에 마찰계수가 다소 큰 글라스테이프를 감아 붙인 후 목적한 바의 클램핑 작업을 해주도록 하여 왔다.As is well known, the deflection yoke of the CRT is provided with clamping means for clamping the deflection yoke assembly back to the CRT outer circumferential surface, which is usually arranged radially to surround the CRT. The resin material clamp elements are fixed to the outer circumferential surface of the CRT neck by a fastening band wound on the outer circumferential surface thereof, so that the clamp elements of the resin material having a small coefficient of friction are fixed to the outer surface of the neck part without slip flow. In order to guarantee that, the glass tape is wound on the outer surface of the neck part with a large friction coefficient, and then the clamping work is performed.

따라서 종래의 클램프부구조는 브라운관 네크부에 대한 별도의 번거로운 테이프 감기 작업을 필요로 할 뿐만 아니라 그러면서 상기 클램프요소들 및 테이프사이, 그리고 테이프와 네크부사이에 만족할 만한 안정적인 마찰접촉력이 나타나기 어렵기 때문에 시간경과에 따라 또는 외부로부터의 사소한 충격, 잔동등에 의해 클램프부의 조임상태가 이완되는 일이 잦은 것등의 문제점이 있었다.Therefore, the conventional clamp part structure not only requires a separate cumbersome tape winding operation for the CRT neck part, but also satisfactory stable frictional contact force between the clamp elements and the tape and between the tape and the neck part is difficult to exhibit. There has been a problem that the tightening state of the clamp part is frequently relaxed due to a lapse of time, or a slight impact from the outside, or afterglow.

본 고안은 편향요크 클램프부에 대한 간단하면서 효과적인 구조개선을 통해 위와 같은 종래의 문제점을 완전히 해소할 수 있게 된 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is able to completely solve the above conventional problems through a simple and effective structure improvement for the deflection yoke clamp, it will be described in detail based on the accompanying drawings as follows.

도면중 부호 1은 본 고안의 클램프구조를 가지는 편향요크조립체, 2는 이 편향요크 조립체가 설치되는 브라운관, 3은 브라운관 네크부를 각각 나타낸다.In the drawings, reference numeral 1 denotes a deflection yoke assembly having a clamp structure of the present invention, 2 denotes a CRT tube, and 3 denotes a CRT neck portion.

도시된 예에서 상기 편향요크조립체(1)의 후부에는 네크부(3) 외주면을 감싸도록 방사상으로 평행배치된 복수의 클램프요소(4)들과 이 클램프요소(4)들 외주면에 권착된 체결밴드(5)를 포함하는 클램프가 설치되어 있다.In the illustrated example, a plurality of clamp elements 4 radially arranged parallel to the outer circumferential surface of the neck portion 3 and a fastening band wound around the outer circumferential surfaces of the clamp elements 4 are arranged at a rear portion of the deflection yoke assembly 1. A clamp including (5) is provided.

본 고안은 상기 편향요크조립체(1)의 클램프 요소(4)들 내면에 마찰계수가 큰 내열, 내마모성의 탄성재, 예컨대 실리콘고무로 된 코팅층(6)를 형성하여서 된 것이다.The present invention is achieved by forming a coating layer 6 made of heat-resistant, wear-resistant elastic material, such as silicone rubber, having a large coefficient of friction, on the inner surfaces of the clamp elements 4 of the deflection yoke assembly 1.

이와 같이 된 본 고안은 마찰계수가 큰 코팅층(6)이 상기 클램프요소(4)들 내면에 미리 제공되어 있어 이들 클램프요소(4)가 상기 코팅층(6)을 통해 충분히 큰 마찰접촉력으로 유리재의 네크부(3) 외주면에 안정적으로 밀착고정되어질 수 있기 때문에 종래와 같이 네크부(3) 외주면에 대한 별도의 번거로운 테이핑작업이 전혀 필요없고 그러면서 상기 코팅층(6)이 클램프요소(4)에 일체화된 상태로 최대한 안정된 불변의 마찰 고정력을 클램프요소(4)들 및 네크부(3)사이에 제공하게 되기 때문에 시간경과나 외부로부터의 충격, 진동등에 관계없이 편향요크 조립체(1)가 항시 견실한 고정상태를 유지토록 할 수 있으며, 더욱이 이러한 작용효과를 추가경비가 별로 들지 않는 간단하고 효과적인 구조 개선을 통해 얻어낼 수 있어 그 실용성인 탁월한 신규유용한 고안인 것이다.The present invention has a coating layer 6 having a large coefficient of friction in advance provided on the inner surface of the clamp elements 4 such that the clamp element 4 is made of a neck of glass material with a sufficiently large frictional contact force through the coating layer 6. Since the part 3 can be stably adhered to the outer circumferential surface, there is no need for a separate cumbersome taping operation on the outer circumferential surface of the neck portion 3 as in the prior art, and the coating layer 6 is integrated with the clamp element 4. As a result of providing the most stable and constant frictional fixing force between the clamp elements 4 and the neck portion 3, the deflection yoke assembly 1 is always firmly fixed regardless of the passage of time, impact or vibration from the outside. In addition, this effect can be obtained through simple and effective structural improvement that does not cost much additional cost. It will anin.
