본 고안은 브라운관의 섀도우 마스크에 관한 것으로 특히 스피커의 음파에 의한 화면의 떨림을 방지할 수 있는 섀도우 마스크에 관한 것이다.The present invention relates to a shadow mask of a cathode ray tube, and more particularly to a shadow mask capable of preventing image shaking due to sound waves of a speaker.

섀도우 마스크(Shadow Mask)는 전자빔이 통과하는 다수개의 구멍이 뚫린 얇은 금속판으로서 프레임(Frame)에 스폿 용접되고, 프레임 측면에 용접된 홀더(Holder)가 판넬(Panel)에 부착된 서터드 핀(Stud Pin)을 삽입하는 방식으로 판넬에 장착된다.A shadow mask is a thin metal plate with a plurality of holes through which an electron beam passes, and is spot welded to a frame, and a stud pin with a holder welded to the side of the frame is attached to a panel. It is mounted on the panel by inserting a pin).

이러한 섀도우 마스크를 용접부위를 중심으로 살펴보면 제1도에 도시된 바와 같이 종래의 섀도우 마스크(10)는 스커트(11)에서 일정부위 양측면을 삼각형으로 절단하여 용접부(12)를 형성시켜 용접점(13)을 위치시킨다. 그러나 이러한 종래의 섀도우 마스크는 TV가 대형화 및 고음질화 되므로 스피커의 음파에 의해 진동이 TV샷시(Chassis)를 거쳐 프레임으로 전달되어 섀도우 마스크로 전달될때 용접부에서 진동을 흡수하지 못하므로, 섀도우 마스크의 진동에 의한 화면의 떨림 현상(Micro Ponic)이 일어나는 문제점이 있었다.As shown in FIG. 1, the shadow mask 10 is formed by cutting a triangle on both sides of a portion of the skirt 11 into triangles to form a weld 12. ). However, since such a conventional shadow mask has a larger and higher quality TV, vibration is transmitted to the frame through the TV chassis by the sound waves of the speaker, and thus the vibration is not absorbed by the weld when transmitted to the shadow mask. There was a problem that the screen shake caused by (Micro Ponic) occurs.

이에 본 고안은 프레임의 진동을 흡수하여 자체의 진동을 최소화하여 화면의 떨림 현상을 방지하는 섀도우 마스크를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a shadow mask that absorbs the vibration of the frame to minimize vibration of the frame and thus prevents the shaking of the screen.

위와 같은 목적을 달성하기 위하여 본 고안의 섀도우 마스크는 용접부가 스커트 끝단보다 길게 돌출되고 양측면에 절단홈이 형성되며, 용접부 하부 위치에 용접점을 두며, 각변마다 다수개인 것을 특징으로 한다.In order to achieve the above object, the shadow mask of the present invention has a welded portion protruding longer than the end of the skirt, and cutting grooves are formed on both sides thereof, and a welded point is provided at the lower portion of the welded portion, and each of the shadow masks is characterized by a large number.

본 고안의 특징에 의하면 프레임의 진동이 섀도우 마스크 용접부에서 흡수되어 섀도우 마스크의 진동에 의한 화면의 떨림 현상을 방지할 수 있다.According to a feature of the present invention, the vibration of the frame is absorbed by the shadow mask welding part, thereby preventing the shaking of the screen due to the vibration of the shadow mask.

이하 도면을 참조하여 본고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2도에 도시된 바와 같이 본 고안의 섀도우 마스크(20)는 용접부(22)가 스커트(21)의 각변마다 2개 이상씩이며, 용접부(22) 양측면은 절단홈이 형성되어 있으며, 용접부(22)는 스커트(21) 끝단보다 길게 돌출되어 있다. 용접점(23)은 용접부(22)하부에 위치시킨다.As shown in FIG. 2, the shadow mask 20 according to the present invention has two or more welded parts 22 for each side of the skirt 21, and both sides of the welded part 22 are formed with cutting grooves. 22 protrudes longer than the end of the skirt 21. The welding point 23 is located under the weld 22.

이하 본고안의 작용 효과를 설명한다.The effect of this proposal will be described below.

스피커의 음파에 의한 진동이 TV샷시를 거쳐 프레임에 전달되면 프레임의 진동은 먼저 섀도우 마스크(20)의 용접점(23)으로 전달된다. 용접점(23)에서의 진동은 용접부(22)상부, 측면이 절단되기 시작한 부위까지의 용접부(22)부분이 스프링처럼 진동을 흡수해주므로 섀도우 마스크(20)자체의 진동을 최소화 할 수 있다.When the vibration of the sound wave of the speaker is transmitted to the frame through the TV chassis, the vibration of the frame is first transmitted to the welding point 23 of the shadow mask 20. The vibration at the welding point 23 may minimize the vibration of the shadow mask 20 itself because the portion of the welding part 22 up to the upper part of the welding part 22 and the side where the side starts to be cut absorbs the vibration like a spring.

이와 같이 본고안의 섀도우 마스크는 스피커 음파에 의한 섀도우 마스크의 진동을 최소화 하므로서 화면의 떨림 현상을 방지하는 효과가 있어 브라운관의 품질을 향상시킨다.In this way, the shadow mask in this paper minimizes the vibration of the shadow mask caused by speaker sound waves, thereby preventing the shaking of the screen, thereby improving the quality of the CRT.
