Abstract
본 고안은 브라운관 제조에 쓰이는 인너쉴드 형상에 관한 것이다.The present invention relates to the inner shield shape used in the manufacture of CRT.
종래에는 프레임과 평행하게 겹쳐진 인너쉴드를 클립으로 결합시켰으나 체결력이 부족하여 외부에서 힘이 가해질 경우 인너쉴드가 유동되거나 이탈되는 문제점이 있었다.Conventionally, the inner shield overlapped in parallel with the frame is coupled with a clip, but there is a problem that the inner shield flows or leaves when a force is applied from the outside due to a lack of fastening force.
본 고안은 인너쉴드의 클립 체결용 홈 주변부를 돌출되도록 굴곡부를 형성시켜 클립으 체결력을 향사시켰다.The present invention is to form a bent portion to project the peripheral portion of the clip fastening groove of the inner shield to improve the fastening force of the clip.
이에 따라 인너쉴드를 프레임에 견고하게 결합시키므로써 인너쉴드의 유동이나 이탈을 방지하여 브라운관의 품질을 향상시키는 효과가 있다.Accordingly, the inner shield is firmly coupled to the frame, thereby preventing the inner shield from flowing or escaping, thereby improving the quality of the CRT.

본 고안은 브라운관 제조에 관한 것으로 특히 프레임(Frame)에 결합되는 인너쉴드(Inner Shield)의 형상에 관한 것이다.The present invention relates to the production of CRT, and more particularly to the shape of the inner shield (Inner Shield) is coupled to the frame (Frame).
인너쉴드는, 전자총이 조사한 전자빔이 지자기의 영향으로 이동이 생기는데, 이러한 지자기의 영향을 감소시켜 스크린 품위를 떨어뜨리지 않도록 브라운관 내면에 부착되는 얇은 금속판을 말한다. 이러한 인너쉴드(2)는 제1도 (a)와 같이 새도우 마스크(Shadow Mask)를 지지하는 프레임(1)에 클립(Clip)을 이용하여 결합되어 있다.The inner shield is a thin metal plate attached to the inner surface of the CRT so that the electron beam irradiated by the electron gun is moved by the influence of the geomagnetism, so as to reduce the influence of the geomagnetism and not degrade the screen quality. The inner shield 2 is coupled to the frame 1 supporting the shadow mask as shown in FIG. 1 (a) by using a clip.
종래의 인너쉴드(2)는 제1도 (b)에 도시되어 있듯이 프레임(1)과 평행상태로 겹쳐져 홈에 삽입된 클립(3)에 의해 결합되어 있다. 이때 인너쉴드(2)는 클립(3) 상단부의 누르는 압력을 받고는 있으나 클립(3)과의 접촉부위가 좁고 프레임(1)과 평행하게 밀착되어 있으므로 클립(3)이 누르는 압력도 크지 않다. 따라서 인너쉴드는 프레임에 안정되게 결합되어 있지 못하므로 운송, 이동, 취급중에 생기는 외부의 약한 충격에도 이탈되기 쉬운 문제점이 있었다.The conventional inner shield 2 is joined by a clip 3 inserted in a groove overlapping in parallel with the frame 1 as shown in FIG. At this time, the inner shield (2) is under pressure to press the upper end of the clip (3), but the contact area with the clip (3) is in close contact with the frame (1) in close contact with the clip (3) is not large. Therefore, since the inner shield is not stably coupled to the frame, there is a problem that the inner shield is easily separated from the external weak impact generated during transportation, movement, and handling.
이에 본 고안은 인너쉴드와 프레임의 결합을 견고하고 안정되게 하는 것을 목적으로 한다.Therefore, the present invention aims to make the inner shield and the frame tight and stable.
위와 같은 목적을 달성하기 위하여 본 고안은 클립의 결합력을 높이기 위하여 인너쉴드의 클립 체결용 홈 주위를 상부로 돌출되도록 굴곡진 형상으로 만드는 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that it is made in a curved shape so as to protrude upwards around the clip fastening groove of the inner shield to increase the coupling force of the clip.
본 고안의 특징에 의하면 인너쉴드는 클립상부에 의해 눌러지는 압력이 커지고 클립과의 접촉부위 이외의 주변부에서도 클립의 누르는 압력이 전달되게 된다.According to a feature of the present invention, the inner shield is pressurized by the upper portion of the clip is increased, and the pressing pressure of the clip is also transmitted in the peripheral portion other than the contact portion with the clip.
이하 제2도를 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIG. 2.
제2도에서 보듯이 본 고안에서는 인너쉴드(5)의 클립 체결용 홈 주위부분을 프레임(1)과 벌어지도록 굴곡부(6)를 형성시킨다.As shown in FIG. 2, in the present invention, the bent portion 6 is formed to open the peripheral portion of the clip fastening groove of the inner shield 5 with the frame 1.
이에 따라 클립(3)이 인너쉴드(5) 프레임(1)을 결합시켜 주는 힘, 즉 인너쉴드(5)를 누르는 압력이 커진다. 또 클립과 접촉하는 인너쉴드(5)의 접촉부 이외의 주변부에도 누르는 압력이 전달되므로 체결력이 강화된다.Thereby, the force which the clip 3 couple | bonds the inner shield 5 frame 1, ie, the pressure which presses the inner shield 5, becomes large. In addition, since the pressure is transmitted to the peripheral portions other than the contact portion of the inner shield 5 in contact with the clip, the tightening force is strengthened.
위와 같이 본 고안은 인너쉴드와 프레임을 견고하고 안정되게 결합시키므로써 인너쉴드가 유동되거나 이탈되는 것을 방지하여 브라운관의 품질을 향상시키는 효과가 있다.As described above, the present invention has an effect of improving the quality of the CRT by preventing the inner shield from flowing or leaving by combining the inner shield and the frame firmly and stably.
