본 고안은 음극선관용 이너실드에 관한 것으로, 특히 이너실드의 변형을 감소시키고자 한 음극선관용 이너실드에 관한 것이다.The present invention relates to an inner shield for cathode ray tubes, and more particularly to an inner shield for cathode ray tubes intended to reduce deformation of the inner shield.
일반적으로, 음극선관에는 여러 부품이 장착되어 있는데, 그 중에서 패널의 내측 공간부에 새도우 마스크 및 프레임이 장착되어 있고, 이 프레임에는 클립을 통해 이너실드가 구비되어 있다. 이 이너실드의 지자계의 영향을 감소시키고, 난반사를 방지할 목적으로 설치된 것이다.Generally, a cathode ray tube is equipped with various components, among which a shadow mask and a frame are mounted in the inner space of the panel, and the frame is provided with an inner shield through a clip. The inner shield is designed to reduce the influence of the geomagnetic field and to prevent diffuse reflection.
종래에는 첨부된 예시 도면 제 1 도 및 제 2 도에 도시된 바와 같이, 튜브(10)안의 프레임(20)에 장착되는 이너실드(30)가 원추형을 이루면서 형성되어 있는데, 이 이너실드(30)의 측벽(31)은 평활한 면으로만 형성되어 있다. 따라서, 이러한 이너실드(30)가 대형화되는 경우에, 얇은 판으로 이루어진 이너실드(30)의 측벽(31)이 상대적으로 약해져 튜브(10)의 내측으로 변형되어 전자총으로 부터 주사되는 전자비임의 새도우가 발생되는 문제점이 있었다.Conventionally, as shown in FIGS. 1 and 2 of the accompanying drawings, the inner shield 30 mounted on the frame 20 in the tube 10 is formed in a conical shape, and the inner shield 30 is formed. The side wall 31 of is formed only in the smooth surface. Therefore, when the inner shield 30 is enlarged in size, the side wall 31 of the inner shield 30 made of a thin plate is relatively weak and is deformed into the inside of the tube 10 to be shadowed by the electron beam. There was a problem that occurred.
이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 튜브 안의 프레임에 장착되는 이너실드에 있어서, 상기 이너실드의 측벽부에 단차를 두고 절곡부가 형성된 구조로서, 이너실드의 변형을 방지하도록 한 것이다.The present invention has been devised to solve the above problems, in the inner shield is mounted to the frame in the tube, the bent portion is formed with a stepped side wall portion of the inner shield, to prevent deformation of the inner shield It is.
이에 본 고안을 첨부된 예시 도면에 의거 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.
본 고안은 첨부된 예시 도면 제 3 도에 도시된 바와 같이 튜브(10)의 프레임(20)에 장착되는 이너실드(30)에 있어서, 상기 이너실드(30)의 측벽부(40)에 단차를 두고 절곡부(50)가 형성된 구조로 되어 있다.According to the present invention, in the inner shield 30 mounted on the frame 20 of the tube 10 as shown in FIG. 3 of the accompanying drawings, the stepped portion of the side wall portion 40 of the inner shield 30 is provided. It has a structure in which the bent part 50 is formed.
이와 같이 구성된 본 고안의 작용 및 효과는 다음과 같다.The operation and effects of the present invention configured as described above are as follows.
본 고안은 이너실드(30)를 튜브(10)안에 조립하고자 하는 경우, 먼저 소정의 위치로 운반하여야 하므로 다수개의 이너실드(30)를 적재하게 된다. 이 때, 적재하는 과정에서 이너실드(30)까지 충돌하더라도 이너실드(30)의 측벽부(40)에 단차를 두고 절곡부(50)가 형성되어 있어 외부의 충격력을 상쇄시켜 변형이 방지된다. 또한, 예기치 않은 충격을 받더라도 이너실드(30)의 측벽부(40)가 변형되지 않으며, 관종에 대형화됨에 따라 이너실드(30)의 크기가 대형화되더라도 측벽부(40)가 약화되어 튜브(10)의 내측으로 변형되지 않는 것이다.In the present invention, when the inner shield 30 is to be assembled into the tube 10, first, the inner shield 30 must be transported to a predetermined position so that a plurality of inner shields 30 are loaded. At this time, even when colliding up to the inner shield 30 in the loading process, the bent portion 50 is formed with a step on the side wall portion 40 of the inner shield 30, and the deformation is prevented by offsetting the external impact force. In addition, the side wall portion 40 of the inner shield 30 is not deformed even when subjected to an unexpected impact, and as the size of the inner shield 30 is enlarged as the size of the inner shield 30 increases, the side wall portion 40 is weakened and the tube 10 is reduced. It will not deform inside.
이와 같이 본 고안에 이너실드의 측벽부가 조립시 변형되지 않고 형태를 그대로 유지할 수 있어 전자총으로부터 방출되는 전자비임의 차단을 방지하여 화면의 품위를 향상시킬 수 있는 효과가 있다.As described above, the sidewall portion of the inner shield can be maintained without being deformed during assembly, thereby preventing the blocking of the electron beam emitted from the electron gun, thereby improving the quality of the screen.
