Description

영상표시기기의 디가우싱 코일 고정구조{Fixing structure of Degaussing coil in Display device}Fixing structure of Degaussing coil in Display device}

본 발명은 영상표시기기에 관한 것으로서, 보다 상세하게는 영상표시기기에 장착되는 디가우싱 코일의 고정구조에 관한 것이다.The present invention relates to an image display device, and more particularly, to a fixing structure of a degaussing coil mounted on an image display device.

일반적으로 텔레비전이나, 모니터와 같이 음극선관을 이용한 영상표시기기에는 지자계의 영향으로 음극선관이 놓이는 방향에 따라 화상이 변형되는 현상을 방지하는 디가우싱(degaussing) 장치가 구비되어 있다.In general, a video display device using a cathode ray tube such as a television or a monitor is provided with a degaussing device that prevents the image from being deformed according to the direction in which the cathode ray tube is placed due to the influence of the geomagnetic field.

상기 디가우싱 장치는 음극선관 주위에 설치된 디가우싱 코일과, 상기 디가우싱 코일에 전압을 인가하여 음극선관에 형성된 자계를 제거하는 제어회로를 포함하여 이루어진다.The degaussing apparatus includes a degaussing coil installed around the cathode ray tube, and a control circuit for removing a magnetic field formed in the cathode ray tube by applying a voltage to the degaussing coil.

도 1에 나타난 것과 같이 상기 디기우싱 코일(10)은 브라운관(C)의 상하방에 각각 한 개씩 장착되는데, 디가우싱 코일의 고정구조는 디가우싱 코일(10)의 양선단이 브라운관(C)의 상하 모서리에 구비된 취부 브라켓(12)에 끼워지고, 상하 디가우싱 코일(10)이 타이밴드(tie band)(20) 등의 고정수단에 의해 서로 묶임으로써 흔들림이 방지되는 방식으로 이루어져 있다.As shown in Figure 1, the degaussing coil 10 is mounted one by one each in the upper and lower sides of the Brown tube (C), the degaussing coil fixed structure is the both ends of the degaussing coil 10 is Brown tube ( C) is fitted to the mounting bracket 12 provided in the upper and lower corners, and the upper and lower degaussing coils 10 are tied to each other by fixing means such as tie bands 20 to prevent shaking. consist of.

여기서, 상기 타이밴드(20)는 소정길이의 밴딩부(201)와, 상기 밴딩부(201)의 일측 선단에 구비되어 밴딩부(201)의 타측 선단을 결속하는 클립(202)으로 이루어져 있으며, 상기 클립(202)에 밴딩부(201)가 결속되어 폐곡선을 이루게 된다.Here, the tie band 20 is composed of a bending portion 201 of a predetermined length and a clip 202 provided at one end of the bending portion 201 to bind the other end of the bending portion 201, The bending portion 201 is bound to the clip 202 to form a closed curve.

따라서, 이러한 종래의 디가우싱 코일 고정구조에 의하면 양 디가우싱 코일(10)(10)이 타이밴드(20)에 의해 잡아당겨진 상태로 고정되기 때문에 흔들림이 방지되어 안정된 디가우싱 작용을 수행하게 된다.Therefore, according to the conventional degaussing coil fixing structure, since both degaussing coils 10 and 10 are fixed in a pulled state by the tie band 20, shaking is prevented to perform a stable degaussing action. Done.

그러나, 상술한 바와 같은 종래의 디가우싱 코일 고정구조에 의하면 타이밴드(20)를 이용하여 상하 디가우싱 코일(10)(10)을 서로 고정하는 과정에서 밴딩부(201)를 클립(202)에 결속시키는 번거로운 작업을 필요로 하게 됨으로써 영상표시기기의 생산성이 저하된다는 문제점이 발생한다.However, according to the conventional degaussing coil fixing structure as described above, the banding portion 201 is clipped 202 in the process of fixing the upper and lower degaussing coils 10 and 10 by using the tie band 20. By requiring a cumbersome work to bind to the ()) there is a problem that the productivity of the image display device is lowered.

또한, 밴딩부(201)와 클립(202)의 결속 시 작업자에 따라 밴딩부(201)에 대한 클립(202)의 결속 위치가 달라지기 때문에 양 디가우싱 코일(10)(10)간의 간격을 일정하게 유지할 수 없게 되는데, 이에 따르면 디가우싱 코일(10)의 형태가 불균일하게 됨으로써 결과적으로 소자(消磁)효과가 저하되는 등, 영상표시기기의 상품성이 떨어진다는 문제점이 발생한다.In addition, since the binding position of the clip 202 with respect to the bending portion 201 varies depending on the operator when the bending portion 201 and the clip 202 is bonded, the distance between the degaussing coils 10 and 10 is increased. Since the shape of the degaussing coil 10 becomes non-uniform, this causes a problem that the merchandise of the image display device is inferior, such as deterioration of the element effect.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로, 상하 양 디가우싱 코일의 고정 작업이 수월해지고, 고정강도가 일정하게 유지되도록 함으로써 영상표시기기의 생산성 및 상품성 향상에 도움이 되는 디가우싱 코일 고정구조의 제공을 목적으로 한다.The present invention has been made to solve the above-described problems, the degaussing to facilitate the fixing of the upper and lower degaussing coils, and to maintain a constant fixed strength to help improve the productivity and productability of the image display device An object of the present invention is to provide a coil fixing structure.
