본 고안은 칼라브라운관에 있어서, 새도우마스크를 설치지지하기 위한 프레임의 구조개선에 관한 것이다.The present invention relates to a structural improvement of a frame for supporting a shadow mask in a color brown tube.
주지된 바와 같이 칼라브라운관에는 전자총으로 부터 방출된 청, 녹, 적의 전자비임들을 해당 형광점들에 정확히 선택랜딩시켜 소망하는 바의 칼라화상을 얻어내도록 하기 위한 새도우마스크라는 특유의 색선택구조물이 설치사용 되는데, 이 새도우마스크는 보통 브라운관 판넬내측의 스터드핀과 협력작용하는 홀더가 부착된 일정형태의 프레임을 통해 판넬내측에서 설치지지된다.As is well known, the color-brown tube is equipped with a unique color selection structure called shadow mask to precisely select and land the blue, green, and red electron beams emitted from the electron gun to the corresponding fluorescent points to obtain the desired color image. These shadow masks are usually installed inside the panel via some type of frame with holders that cooperate with the stud pins inside the CRT panel.
본 고안은 위와 같은 새도우마스크 프레임 중에서 특히 코너부에 홀더가 부착되는 종류의 프레임의 구조개선과 관련한 것이다.The present invention relates to the improvement of the structure of the type of the frame is attached to the holder, especially in the corner of the shadow mask frame as described above.
종래에 재작사용되어 왔던 이러한 종류의 새도우마스크 프레임은 제 1 도에서 보는 바와 같이 한 단일체의 프레임소재를 소망하는 프레임 형태로 포밍(forming)하고 중앙 대공(1')을 타발해내어서 만들어진 단일체의 프레임(1)을 형성한 후 홀더(2)들을 용접부착한 구조로 되어 있었기 때문에 그 제작이 매우 까다로울 뿐만 아니라 중앙 대공(1')을 타발해낼 때 상당면적의 폐기 스크랩이 발생하기 때문에 재료의 낭비가 심한 문제점이 있었다.This type of shadow mask frame, which has been reworked in the past, is formed by forming a single frame material into a desired frame shape as shown in FIG. 1 and punching out the central hole 1 '. Since the holder 1 was welded after the frame 1 was formed, the fabrication of the frame 1 was not only very difficult, but also a large amount of waste scrap occurred when the central hole 1 'was punched out. There was a serious problem.
본 고안은 이러한 종래의 문제점을 해소하기 위해 안출한 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional problem, it will be described in detail based on the accompanying drawings as follows.
제 2 도는 본 고안의 한 바람직한 실시예에 따른 새도우마스크 프레임(10)의 정면구조를 도시한 것인데, 이 프레임(10)은 도시된 바와 같이 프레임(10)전체가 서로 마주보는 한쌍의 장변부재(10a)와 서로 마주보는 한쌍의 단변부재(10b)들로 분리형성되고, 이들 부재를 홀더(20)들과 함께 도시된 형태로 용접조립하여서 이루어진 것이다.2 is a front view of the shadow mask frame 10 according to an embodiment of the present invention, the frame 10 is a pair of long side members (the whole frame 10 facing each other, as shown) It is formed by separating a pair of short side members 10b facing each other with 10a), and welding these members together with the holders 20 in the form shown.
상기 제 2 도의 실시예에 있어서는 분리형성된 한 장변부재(10a)와 한 단변부재(10b)의 서로 잇대어지는 부위들에 이들 부재의 조합시 상호 적합하게 중첩될 수 있는 코너벽부(10a')(10b')들 및 코너벽부(10a'')(10b'')들이 제공되고, 이들 코너벽부(10a')(10b ') 및 코너벽부(10a'')(10b'')가 상호 중첩되게 상기 장변 및 단변부재(10a)(10b)들을 조합한 후 홀더(20)를 상기 중첩된 코너벽부(10a')(10b') 및 코너벽부(10a'')(10b'')들과 함께 용접고정시켜 프레임(10)을 이루도록 되어있다.In the embodiment of FIG. 2, the corner wall portions 10a 'and 10b, which can be suitably overlapped with each other in the combination of the formed long side member 10a and the short side member 10b, are joined together. 'And corner wall portions 10a' 'and 10b' 'are provided, and the long sides such that the corner wall portions 10a' and 10b 'and the corner wall portions 10a' 'and 10b' 'overlap each other. And combining the short side members 10a and 10b and welding the holder 20 together with the overlapping corner wall portions 10a 'and 10b' and the corner wall portions 10a '' and 10b ''. The frame 10 is formed.
제 3 도는 본 고안의 다른 가능한 실시예를 도시한 것인데, 이 실시예에 있어서는 분리형성된 한 장변부재(10a)와 한 단변부재(10b)가 서로 잇대어지는 부위들에 이들 부재의 조합시 상호일직선으로 잇대어지는 절반크기씩의 코너벽부(10a''')(10b''')들이 제공되어 있고, 이와 같이 일직선으로 잇대어진 코너벽부(10a''')(10b''')들을 홀더(20)와 함께 용접고정시켜 프레임(10)을 이루도록 되어 있다.3 shows another possible embodiment of the present invention, in which the long side member 10a and the short side member 10b, which are separately formed, are joined to each other at a position where these members are joined to each other in a straight line. There are provided corner wall portions 10a " '10b' ", which are joined in half sizes, and thus the holders 20 are connected to the straight corner wall portions 10a " " The welding is fixed together with the frame 10.
이와 같이 된 본 고안의 새도우마스크 프레임은 프레임(10) 전체가 상술한 바와 같은 장변부재(10a)들 및 단변부재(10b)들로 분리형성된 후 이들 부재를 홀더(20)와 함께 용접고정시켜 목적하는 바의 프레임을 이루도록 되어 있기 때문에 프레임 전체를 한 단일체의 프레임소재로 부터 포밍하고 필요한 구멍을 타발하여 제작해야 했던 종래에 비해 프레임 제작을 보다 간편용이하게 할 수 있을 뿐만 아니라 중앙 대공(10')의 형성을 위한 타발 스크랩이 발생하는 않으므로 재료의 낭비를 극소화할 수 있게 된 뛰어난 이점들을 지닌 것이다.The shadow mask frame of the present invention as described above is formed by separating the long frame member (10a) and the short side member (10b) as described above the entire frame (10) by welding and fixing these members together with the holder (20) Since it is designed to form a frame of the bar, not only can the frame manufacturing be more convenient than the conventional one, which had to form the entire frame from a single frame material and punched out the necessary holes, but also the center anti-air hole (10 '). Since punching scraps do not occur for the formation of, it has excellent advantages that minimize waste of material.
