본 고안은 전자빔의 색선별전극인 섀도우마스크(Shadow Mask)를 지지하는 써포트 프레임(Support Frame)에 관한 것으로써, 좀 더 구체적으로는 그 구조를 개선하여 섀도우마스크의 고정작업시 섀도우마스크가 변형되지 않도록 한 것이다.The present invention relates to a support frame for supporting a shadow mask, which is a color selection electrode of an electron beam. More specifically, the structure is improved so that the shadow mask is not deformed when the shadow mask is fixed. It is to avoid.

첨부도면 제 1 도는 일반적인 칼라음극선관을 나타낸 종단면도로써, 전방의 판넬(1)과, 상기 판넬과 결합되어 음극선관(진공용기)을 구성하며 후방으로 전자총(도시는 생략함)이 봉입되는 네크(Neck)부(2)가 형성된 판넬(3)과, 상기 판넬(1)의 내면에 도트(Dot) 또는 스트라이프(Stripe)타입으로 도포된 적, 녹, 청의 형광체층(4)과, 상기 형광체층의 근접부에 위치되게 판넬에 위치되어 색선별역할을 하는 섀도우마스크(5)와, 상기 섀도우마스크를 판넬에 고정시켜 주는 써포트 프레임(6)과, 상기 판넬의 외주연에 설치되어 전자총에서 발사되는 전자빔을 편향시키는 편향요크(7)로 구성된다.1 is a longitudinal cross-sectional view showing a general color cathode ray tube, which is coupled to the front panel 1 to form a cathode ray tube (vacuum container), and a neck in which an electron gun (not shown) is enclosed rearward. A panel 3 on which the neck part 2 is formed, a phosphor layer 4 of red, green, and blue applied on the inner surface of the panel 1 in a dot or stripe type, and the phosphor A shadow mask (5) positioned on the panel to be positioned in the vicinity of the layer to serve as color screening, a support frame (6) for fixing the shadow mask to the panel, and installed at an outer periphery of the panel to shoot from an electron gun And a deflection yoke 7 for deflecting the electron beam.

따라서 전자총에서 발사된 전자빔은 색선별역할을 하는 섀도우마스크(5)의 미세한 구멍을 통해 상기 판넬(1)의 내면에 도포된 소정의 형광체에 부딪히게 되므로 전자총에 인가된 영상신호를 재현하게 된다.Therefore, the electron beam emitted from the electron gun hits a predetermined phosphor applied to the inner surface of the panel 1 through the minute hole of the shadow mask 5 which plays a role of color discrimination, thereby reproducing an image signal applied to the electron gun.

상기한 바와 같이 색선별역할을 하는 섀도우마스크(5)를 금형으로 프레스 성형시에는 써포트 프레임(6)과 접속되는 스커트부(skirt)(5a)가 제2도의 θ 각만큼 벌어지는데, 이러한 스커트부의 벌어짐은 스프링 백(Spring Back)량에 의해 결정된다.As described above, during the press molding of the shadow mask 5, which serves as color selection, into a mold, a skirt 5a connected to the support frame 6 is opened by the θ angle of FIG. 2. Is determined by the amount of spring back.

근래에는 음극선관에 인바아(Invar)재질의 섀도우마스크를 적용하기 때문에 기존의 재질에 비해, 스프링 백량이 커지게 되고, 이에 따라 스커트부의 벌어짐량도 커지게 된다.In recent years, since the Invar material shadow mask is applied to the cathode ray tube, the amount of spring back is increased, and thus the amount of opening of the skirt portion is increased.

제 2 도는 종래의 써포트 프레임에 섀도우마스크가 고정된 상태의 종단면도로써, 써포트 프레임(6)의 절곡부(6a)가 수직으로 되어 있기 때문에 섀도우마스크(5)의 프레스성형시 벌어진 스커트부(5a)를 써포트 프레임(6)의 절곡부(6a)에 용접고정을 위해 삽입시, 특해 섀도우마스크가 써포트 프레임의 내측에 용접되어 고정되는 타입(Mask Inside Frame Assemley : MIFA)의 섀도우마스크에서는 섀도우마스크의 변형이 더욱 심하게 발생되었음은 물론 곡률반경(曲率半經)이 변경되는 불량을 야기시키게 되었다.FIG. 2 is a longitudinal sectional view in which a shadow mask is fixed to a conventional support frame. The bent portion 6a of the support frame 6 is vertical, so that the skirt portion 5a that is formed when the shadow mask 5 is press-molded. In the shadow mask of the type (Mask Inside Frame Assemley: MIFA) in which the shadow mask is welded and fixed to the inside of the support frame when inserting it into the bent portion 6a of the support frame 6 for welding fixation, Not only did the deformation occur more severely, but it also caused a defect in which the radius of curvature was changed.

본 고안은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로써, 써포트 프레임의 절곡부를 섀도우마스크의 스커트부형상과 대응되게 형성하여 섀도우마스크의 용접고정을 위해 접속시에 섀도우마스크의 형상이 변형되지 않도록 하는데 그 목적이 있다.The present invention has been devised to solve such a problem in the related art, and the bent portion of the support frame is formed to correspond to the skirt portion of the shadow mask so that the shape of the shadow mask is not deformed when connected for welding fixing of the shadow mask. The purpose is to avoid it.

상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 써포트 프레임의 절곡부에 섀도우마스크의 스커트부를 고정하도록 된것에 있어서, 상기 써포트 프레임의 절곡부에 섀도우마스크의 스커트부의 경사각과 대응되는 경사각으로 절곡되게 경사면을 형성하여서 된 음극선관의 서포트 프레임 구조가 제공된다.According to an aspect of the present invention for achieving the above object, to be fixed to the skirt portion of the shadow mask to the bent portion of the support frame, bent at an inclination angle corresponding to the inclination angle of the skirt portion of the shadow mask to the bent portion of the support frame A support frame structure of a cathode ray tube formed by forming an inclined surface is provided.

이하, 본 고안을 일 실시예로 도시한 첨부된 도면 제 3 도를 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIG. 3 of the accompanying drawings.

첨부도면 제 3 도는 본 고안의 써포트 프레임에 섀도우마스크가 고정된 상태의 종단면도로써, 본 고안은 섀도우마스크(5)의 스커트부(5a)가 용접고정되는 써포트 프레임(6)의 절곡부(6a)에 스커트부의 경사각(θ)과 대응되는 경사면(6b)을 형성하여 스커트부(5a)가 경사면(6b)에 탄력적으로 접속되도록 되어 있다.FIG. 3 is a longitudinal sectional view in which the shadow mask is fixed to the support frame of the present invention, and the present invention is a bent portion 6a of the support frame 6 to which the skirt portion 5a of the shadow mask 5 is welded and fixed. ), The inclined surface 6b corresponding to the inclination angle? Of the skirt portion is formed so that the skirt portion 5a is elastically connected to the inclined surface 6b.

이와 같이 구성된 본 고안의 작용, 효과를 설명하면 다음과 같다.Referring to the operation, effects of the present invention configured as described above are as follows.

인바아(Invar)재질로 형성된 써포트 프레임(6)의 절곡부(6a)에 섀도우마스크(5)의 스커트부(5a)를 내측으로 압축시키면서 밀어 넣으면 상기 스커트부(5a)가 θ각의 내측으로 압축되었다가 스커트부(5a)의 접속부인 경사면(6b)에 도달하면 자체 탄성력에 의해 초기상태로 환원되어 스커트부(5a)가 경사면(6b)에 긴밀히 접속되므로 섀도우마스크(5)가 변형되지 않게 된다.When the skirt portion 5a of the shadow mask 5 is pressed into the bent portion 6a of the support frame 6 formed of an Invar material while being pressed inward, the skirt portion 5a is moved inward of the θ angle. When it reaches the inclined surface 6b, which is compressed and reaches the connection portion of the skirt portion 5a, it is reduced to its initial state by its elastic force so that the shadow portion 5 is not deformed because the skirt portion 5a is closely connected to the inclined surface 6b. do.

이와 같이 써포트 프레임(6)에 섀도우마스크(5)를 결합하고 난 후에는 종래와 마찬가지로 용접작업으로 이들을 일체화하게 된다.After the shadow mask 5 is coupled to the support frame 6 as described above, these are integrated by welding as in the prior art.

이상에서와 같이 본 고안은 써포트 프레임의 절곡부상에 섀도우마스크의 스커트부의 경사각과 대응되는 경사면을 형성하는 간단한 구조에 의해 이들의 결합작업시 섀도우마스크가 변형되는 것을 미연에 방지할 수 있게 되므로 제품의 신뢰도를 향상시키게 되는 효과를 얻게 된다.As described above, the present invention has a simple structure that forms an inclined surface corresponding to the inclination angle of the skirt portion of the shadow mask on the bent portion of the support frame, thereby preventing the shadow mask from being deformed during the joining operation. The effect is to improve the reliability.
