본 고안은 음극선관에 관한 것으로, 특히 게터부의 구조를 개선하여 전자총의 변위를 방지한 음극선관에 관한 것이다.The present invention relates to a cathode ray tube, and more particularly, to a cathode ray tube in which the structure of the getter part is improved to prevent displacement of the electron gun.

일반적으로 음극선관은 전자총에서 발사된 열전자에 의해 패널내벽에 도포된 형광막을 발광시켜 화상을 얻는 것으로서, 종래 음극선관은 제 1 도에 도시된 바와 전자총부(10)와, 상기 전자총부(10)상단에 설치된 쉴드컵(20)과, 상기 쉴드컵 주위에 설치되어 전자총부(10)를 벌브의 네크부(30) 내벽에 지지하는 복수개의 스페이서(40)와, 상기 쉴드컵(20)에 그 일측이 고정되며, 네크부(30)의 내벽을 따라 만곡되게 길게 형성된 콘테이너 지지편(50a)에 의해 지지되는 게터(50)를 구비하고 있다.In general, a cathode ray tube emits a fluorescent film coated on an inner wall of a panel by hot electrons emitted from an electron gun, thereby obtaining an image. In the related art, a cathode ray tube includes an electron gun portion 10 and an electron gun portion 10 as shown in FIG. A shield cup 20 provided at an upper end, a plurality of spacers 40 installed around the shield cup to support the electron gun part 10 on the inner wall of the neck part 30 of the bulb, and the shield cup 20 One side is fixed, and the getter 50 is supported by the container support piece 50a elongately curved along the inner wall of the neck part 30, and is provided.

상기와 같은 구성을 갖는 종래 음극선관은, 전자총부(10)를 스페이서(40)에 의해 네크부(30) 내면에 지지함에 있어서, 상기 스페이서(40)는 쉴드컵(20)주위에 3개 설치하므로 가장 적절하게 전자총부(10)를 네크부(30)에 지지할 수 있게 하기 위해서는 등간격 즉, 120°의 간격을 가지고 쉴드컵(20)에 설치되어야 하는 것이나, 상기 전자총부(10) 선단에 설치된 쉴드컵(20)의 일측에 게터(50)를 지지하며 탄성을 갖도록 길게 만국되어 형성된 콘테이너 지지편(50a)의 일측이 고정되어 있어, 이를 감안하여 스페이서(40)를 임의의 각도로 쉴드컵(20)에 설치한 뒤 전자총부(10)를 네크부(30)에 지지시키는 것이었다. 하지만 음극선관의 생산과정에서 음극선관의 내부부품의 상호 조합의 필요성에 따라 전자총부(10)와 전극의 위치가 관측의 전후방향으로 변동하며, 또한 펀넬(60)의 각도와 네크부(30)의 내경도 여러 종류로 되어 있어, 콘테이너 지지편(50a)의 탄성력을 감안하여 스페이서(40) 상호 간격을 정하더라도 이에 의해 네크부(30)에 지지되는 전자총부(10)는 상당한 편위를 갖고 네크부(30)에 지지되는 것이다.In the conventional cathode ray tube having the above-described configuration, in supporting the electron gun portion 10 by the spacer 40 on the inner surface of the neck portion 30, three spacers 40 are provided around the shield cup 20. Therefore, in order to most appropriately support the electron gun 10 to the neck 30, it should be installed in the shield cup 20 at equal intervals, that is, at an interval of 120 °, but the tip of the electron gun 10 One side of the container support piece 50a which is formed to support the getter 50 on the one side of the shield cup 20 installed on the container cup 20 is long enough to have elasticity, and in consideration of this, the spacer 40 is shielded at an arbitrary angle. After installing in the cup 20, the electron gun part 10 was supported by the neck part 30. As shown in FIG. However, in the production process of the cathode ray tube, the position of the electron gun unit 10 and the electrode varies in the front and rear direction of the observation according to the necessity of mutual combination of the internal parts of the cathode ray tube, and also the angle of the funnel 60 and the neck portion 30 Since the inner diameter of the container is also various, the electron gun portion 10 supported by the neck portion 30 has a considerable deviation even though the spacers 40 are spaced apart from each other in consideration of the elastic force of the container support piece 50a. It is supported by the part (30).

또한 콘테이너 지지편(50a)은 음극선관이 동작시 편향요크(도시되지 않음)에 의해 발생된 편향자계에 의해 상기 콘테이너 지지편(50a)이 자화되어 콘버어젼스 특성을 떨어뜨리는 등의 문제점이 발생됐다.In addition, the container support piece 50a may have a problem such that the container support piece 50a is magnetized by a deflection magnetic field generated by a deflection yoke (not shown) when the cathode ray tube is operated, thereby degrading the convergence characteristics. done.

본 고안은 상기와 같은 문제점을 감안하여 안출된 것으로서, 게터를 패널 내부에 직접 장착함으로써 게터의 지지편을 생략하여 지지편이 갖고 있는 탄성력을 없애줌으로써 스페이스에 의해 네크부에 지지되는 전자총부의 편위를 막을 수 있고 콘버어젼스 특성이 떨어지는 것을 막을 수 있는 음극선관을 제공함에 그 목적이 있다.The present invention has been devised in view of the above problems, and by directly mounting the getter inside the panel, the support piece of the getter is omitted and the elastic force of the support piece is eliminated, thereby eliminating the deviation of the electron gun supported by the neck by the space. It is an object of the present invention to provide a cathode ray tube which can be prevented and prevents the deterioration of the convergence characteristic.

상기 목적을 달성하기 위하여 본 고안에 따른 음극선관은 전자총부와, 상기 전자총부 선단에 설치된 쉴드컵부와, 상기 쉴드컵부 주위에 구비되어 전자총부를 네크부 내벽에 지지고정하는 복수개의 스페이서와, 상기 네크부내벽을 따라 펀넬내벽에 설치된 게터를 구비하여된 음극선관에 있어서, 상기 게터부가 판넬내벽에 몰입 고정되는 몰입걸림구와 게터부를 지지고정하며 상기 몰입걸림구에 끼워고정할 수 있도록 탄성력을 갖는 걸고리형 스프링 지지체를 구비하여 됨을 특징으로 한다.In order to achieve the above object, the cathode ray tube according to the present invention includes an electron gun part, a shield cup part installed at the tip of the electron gun part, a plurality of spacers provided around the shield cup part to support and fix the electron gun part on the inner wall of the neck part, and the neck part. In the cathode ray tube provided with a getter installed on the inner wall of the funnel, the hook-type spring having an elastic force so as to support the immersion latch and the getter portion immersed fixed to the panel inner wall and to be fixed to the immersion latch opening It is characterized by having a support.

이하 본 고안에 따른 음극선관의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of a cathode ray tube according to the present invention will be described in detail with reference to the accompanying drawings.

제 2 도는 본 고안에 따른 음극선관을 도시한 것으로서, 음극선관(1)은 패널부(도시되지 않음)와 봉합되는 펀넬부(1a) 및 네크부(1b)로써 구성되어지며, 상기 네크부(1b) 내면에는 그 선단에 쉴드컵(3)이 설치된 전자총부(4)가 스페이서(2)에 의해 지지되어 위치고정되며, 상기 펀넬부(1a) 내측면에는 게터부(5)가 마련된다.2 shows a cathode ray tube according to the present invention, the cathode ray tube 1 is composed of a funnel portion 1a and a neck portion 1b sealed with a panel portion (not shown), and the neck portion ( 1b) On the inner surface, the electron gun portion 4 provided with the shield cup 3 at the tip thereof is supported and fixed by the spacer 2, and a getter portion 5 is provided on the inner surface of the funnel portion 1a.

상기 게터부(5)는 게터(5a)를 지지하고 잇는 걸고리형 스프링 지지체(5b)와, 상기 게터지지체(5b)에 삽입되어 고정되는 몰입걸림구(5c)를 구비하여 된 것이며, 상기 몰입걸림구(5c)는 펀넬부(1a)내측면에 몰입고정되어 있다.The getter portion 5 is provided with a hook-type spring support 5b supporting the getter 5a and an immersion latch 5c which is inserted and fixed to the getter support 5b. The sphere 5c is immersed and fixed to the inner surface of the funnel portion 1a.

상기와 같이 본 고안에 따른 음극선관은, 패널부와 펀넬부(1a)를 서로 봉착하기 전에, 게터부(5)를 설치하게 되므로 펀넬부(1a) 내면에 몰입고정된 몰입걸림구(5c)에 게터(5a)를 지지하는 탄성체인 걸고리형 스프링 지지체(5b)를 끼워고정함으로써, 전자총부(4) 선단에 설치된 쉴드컵(3)에 일측을 고정하여 게터(5a)를 지지하도록 길게 만곡되게 형성한 콘테이너 지지편을 생략할 수 있는 것이어서, 콘테이너 지지편의 탄성력을 우려하지 않고, 스페이서(2)에 의해 전자총부(4)를 네크부(1b)에 위치고정시킬 수 있는 것이다. 즉, 쉴드컵(3)에 복수개의 스페이서(2)를 설치함에 있어, 네크부(1b)에 전자총부(4)를 지지할 수 있는 이상적인 간격인 등간격 및 3개의 스페이서(2)를 설치할때는 120°의 간격을 갖도록 하고, 4개의 스페이서(2)를 설치할때는 90°의 간격을 갖도록 설치할 수 있는 것이다.As described above, the cathode ray tube according to the present invention has a immersion latch 5c immersed and fixed to the inner surface of the funnel portion 1a because the getter portion 5 is installed before the panel portion and the funnel portion 1a are sealed to each other. By fastening the hook-type spring support 5b, which is an elastic body supporting the getter 5a, to one side to the shield cup 3 provided at the tip of the electron gun section 4 to be bent long to support the getter 5a. Since the formed container support piece can be omitted, the electron gun part 4 can be fixed to the neck part 1b by the spacer 2, without worrying about the elastic force of the container support piece. That is, in installing the plurality of spacers 2 in the shield cup 3, in the equal intervals and the three spacers 2, which are ideal intervals for supporting the electron gun portion 4 in the neck portion 1b, The interval of 120 °, and when installing the four spacers (2) can be installed to have a distance of 90 °.

이로인해서 상기 스페이서(2)에 의해 지지되는 전자총부(4)를 네크부(1b) 내면에 중심위치에 정확히 오도록 위치고정시킬 수 있는 것이다.Thus, the electron gun portion 4 supported by the spacer 2 can be fixed so as to be exactly at the center position on the inner surface of the neck portion 1b.

또한 종래 콘테이너 지지편이 음극선관이 동작시 자화되어 이에 따라 콘버어젼스 특성이 저하되는 것을 방지할 수 있는 것이며, 불량품을 재생하여 펀넬부(1a)를 재사용할 경우, 펀넬부(1a) 내면에 몰입고정된 몰입걸림구(5c)로부터 걸고리형 스프링 지지체(5b)을 해체시킨 뒤 플래쉬된 게터(5a)를 걸고리형 스프링 지지체(5b)에서 제거하고 새로운 게터(5a)를 걸고리형 스프링 지지체(5b)에 지지시킨뒤 다시 몰립걸림구(5c)로 삽입하면 재사용할 수 있는 것이어서, 코스트 절감을 도모할 수 있는 것이다.In addition, the conventional container support piece is to prevent the magnetization of the cathode ray tube during operation, thereby reducing the convergence characteristics, and immersed in the inner surface of the funnel portion 1a when reusing the funnel portion 1a by regenerating defective products. After dismantling the hook spring support 5b from the fixed immersion latch 5c, the flashed getter 5a is removed from the hook spring support 5b, and the new getter 5a is hooked on the hook spring support 5b. After supporting it, it can be reused by inserting it into the immersion latch 5c, thereby reducing the cost.
