본 발명은 칼라 음극선관에 관한 것으로서, 더 상세하게는 패널 내면의 알루미늄증착막과 펀넬내면의 흑연도전막과의 전기적인 접속에 관한 것이다.The present invention relates to a color cathode ray tube, and more particularly, to an electrical connection between an aluminum deposition film on a panel inner surface and a graphite conductive film on a funnel inner surface.

통상적으로 칼라 음극선관은 제1도에 나타내 보인 바와 같이 형광막(2a)이 형성된 패널(2)의 내측면에 스터드핀(2b)이 마련되고 이 스터드핀(2b)에는 섀도우마스크(3a) 및 인너실드(3b)와 결합된 프레임(3)이 그 외주면에 고정된 훅스프링(3c)에 의해 패널(2)내부에 위치되며, 상기 패널(2)은 내면에 흑연도전막(5a)이 형성되고 그 네크부(5b)에 전자총(6)이 봉입된 펀낼(5)이 봉착되어 된 것이다. 이와 같이 구성된 칼라 음극선관(1)은 펀낼(5)의 네크부(5b)에 장착된 전자총(6)으로 부터 열전자가 방출되어 상기 섀도우마스크(3a)를 통과한 후 형광막(2a)에 랜딩됨으로써 하나의 희소를 이루게 되는데, 상기 형광막(2a)을 발광시킨 열전자는 전자총(6)으로 부터 방출된 후속 열전자가 형광막(2a)에 조사(Landing)되는 것을 방해하게 된다. 따라서 상기 형광막(2a)의 형광체를 발광시키고 남은 열전자를 음극선관의 외부로 접지시키게 되는데 그 경로를 살펴보면 다음과 같다. 즉 형광막의 형광체를 발광시키고 남은 열전자는 블랙메트릭스 및 알루미늄 증착막과, 알루미늄 증착막과 스터드핀을 연결하는 흑연막, 훅스프링, 프레임, 프레임에 고정되어 그 단부가 흑연도전막과 접촉된 콘택트 스프링, 흑연도전막, 애노우드단자를 순차적으로 경유하여 칼라 음극선관의 외부로 접지되게 된다. 그런데, 상기 열전자의 이동 경로중 상기 블랙메트릭스 및 알루미늄 증착막을 연결하는 흑연막은 작업자가 붓으로 칠하여 형성하고 있으므로, 흑연의 도포불량, 또는 패널의 소성 공정시 흑연막이 떨어져 이들의 전기적 접속이 이루어지지 않게 되는 경우가 많았다. 특히, 프레임(3)과 흑연도전막(5a)을 접지시키는 콘택트 스프링(7)은 프레임(3)에 용접하거나, 인너실드(3b)와 프레임(3)을 결합하는 클럽에 의해 고정하게 되므로 이에 따른 많은 작업공수가 소요되어 생산성의 향상을 도모할 수 없는 문제점이 있었다.In general, as shown in FIG. 1, the color cathode ray tube is provided with a stud pin 2b on the inner surface of the panel 2 on which the fluorescent film 2a is formed, and the shadow mask 3a and the stud pin 2b are provided on the inner surface of the panel 2. The frame 3 coupled with the inner shield 3b is positioned inside the panel 2 by a hook spring 3c fixed to its outer circumferential surface, and the panel 2 has a graphite conductive film 5a formed therein. The funnel 5 in which the electron gun 6 is enclosed in the neck part 5b is sealed. In the color cathode ray tube 1 configured as described above, hot electrons are emitted from the electron gun 6 mounted on the neck portion 5b of the funnel 5 and pass through the shadow mask 3a and then landed on the fluorescent film 2a. As a result, one rareness is achieved. The hot electrons emitting the fluorescent film 2a prevent the subsequent hot electrons emitted from the electron gun 6 from being irradiated to the fluorescent film 2a. Therefore, the phosphor of the fluorescent film 2a is emitted and the remaining hot electrons are grounded to the outside of the cathode ray tube. The path is as follows. That is, the remaining hot electrons after emitting the phosphor of the phosphor film are fixed to the black matrix and aluminum deposition film, the graphite film connecting the aluminum deposition film and the stud pin, the hook spring, the frame, and the frame, and the contact springs and graphite whose ends are in contact with the graphite conductive film. The conductive film and the anode terminal are sequentially grounded to the outside of the color cathode ray tube. However, the graphite film connecting the black matrix and the aluminum deposition film in the moving path of the hot electrons is formed by a worker painting with a brush, so that the graphite film may fall off during the coating process of the graphite or the baking process of the panel so that the electrical connection is not made. There were many cases. In particular, the contact spring 7 for grounding the frame 3 and the graphite conductive film 5a is fixed to the frame 3 by welding or by a club that couples the inner shield 3b to the frame 3. There is a problem that can not improve the productivity due to the large number of work labor.
