본 고안은 브라운관의 개터구조체에 관한 것으로 특히, 바튬(6a)이 새도우마스크 및 전자총쪽으로 비산되는 것을 막아주면서 브라운관 내부에서 바튬이 균일하게 비산되도록 하여 브라운관 내부의 진공도를 높여줌으로써 화상을 콘트라스트를 높여주도록 한 브라운관의 게터구조체에 관한 것이다.The present invention relates to the Gator structure of the CRT, in particular, to prevent the scattering of the lithium (6a) toward the shadow mask and the electron gun to ensure that evenly scattered in the inside of the CRT to increase the degree of vacuum inside the CRT to enhance the image contrast It relates to a getter structure of a CRT.
일반적으로 브라운관을 제조할 때 브라운관의 내부를 진공상태로 만들어주기 위해 로터리펌프(Rotary Pump)또는 디퓨젼점프(Diffdusion Pump)로 공기를 외부로 펌핑하여 브라운관 내부 기압을 10-6Torr정도로 만들어준다음, 바튬이 혼입된 게터(Getter)를 외부에서 고주파로 가열하여 비산(flashing)시켜줌으로써 바튬이 브라운관 내부의 공기와 화합되도록 하여 브라운관의 진공도를 10-7Torr이하로 만들어 주게 된다.In general, when manufacturing the CRT, the internal pressure of the CRT is made to 10 -6 Torr by pumping air to the outside using a rotary pump or a diffusion pump to make the inside of the CRT vacuum. In addition, by heating the high-frequency getter in which the lithium is mixed and flashing it, the lithium is combined with the air inside the CRT to make the vacuum degree of the CRT less than 10 -7 Torr.
종래 개터구조체는 제4도에 도시된 바와같이, 게터안테나(31) 선단부에서 퍼널쪽에 스프링(32)이, 퍼널 반대쪽에 캡(33)이 각각 설치되고, 이 캡(33)의 하부 원주둘레에는 바튬(34)이 부착된 구조로 되어, 이러한 게터 구조체를 브라운관 내부에 설치한 상태에서 진공펌프로 브라운관 내부를 배기시킨 다음, 상기 스프링(32)쪽 퍼널 외부에 설치된 봄바딩코일(Bombarding Coil)에 전류를 인가시켜주게 되면, 상기 스프링(32)을 매개로 고주파로 바튬(34)이 상기 캡(33)주변 방사 방향으로 비산하면서 브라운관 내부에 잔류된 공기와 결합되어 브라운관 내부의 진공도를 높여주는 한편, 상기 바튬과 결합된 화합물은 브라운관 내벽이나 전자총, 인너쉴드 또는 새도우미스크에 달라붙게 된다.In the conventional gutter structure, as shown in FIG. 4, a spring 32 is provided on the funnel side at the tip of the getter antenna 31, and a cap 33 is provided on the opposite side of the funnel, and the lower circumferential circumference of the cap 33 is provided. Batteries (34) attached to the structure, such that the getter structure is installed inside the CRT tube, the evacuation of the CRT tube with a vacuum pump, and then to the Bombarding coil (Bombarding Coil) installed outside the funnel on the spring (32) side When the current is applied, the lithium 34 is scattered in the radial direction around the cap 33 at high frequency through the spring 32, and is combined with the air remaining in the CRT to increase the degree of vacuum in the CRT. , The compound combined with the lithium is attached to the inner wall of the CRT, electron guns, inner shields or shadow mice.
그러나 이때 바튬이 전자총쪽으로 비산하게 되면 바튬화합물이 전자총의 전극사이에 끼이게되어 전자총이 동작할 때 아아크가 발생됨으로써 브라운관의 화면특성이 블량하게 되고, 또 많은 양의 바튬화합물이 새도우마스크에 부착하게 될 경우 새도우마스크의 열변형이 불균일하게 일어남으로써 화상이 선명하지 않게되며, 만약 바튬 화합물이 스크린의 알루미늄 증착막에 비산될 경우 휘도를 저하시키는 문제점이 있다.However, when the lithium is scattered toward the electron gun, the lithium compound is sandwiched between the electrodes of the electron gun, and arc is generated when the electron gun is operated. Therefore, the screen characteristics of the CRT are poor, and a large amount of the lithium compound adheres to the shadow mask. If the thermal mask of the shadow mask is non-uniform, the image is not clear. If the lithium compound is scattered on the aluminum deposition film of the screen, there is a problem of lowering the brightness.
이에 본 고안은 상기와 같은 제반 문제점을 해결하기 위해 안출된 것으로, 바튬의 비산 각도를 제어하도록 다수의 관통홀의 형성된 캡을 설치하여 화질을 향상시킬 수 있도록한 브라운관의 게터구조체를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and the object of the present invention is to provide a getter structure of the CRT tube to improve the image quality by installing a cap formed of a plurality of through holes to control the scattering angle of the lithium. have.
상기와 같은 목적을 달성하기 위한 본 고안은, 게터안테나의 선단부에 바튬의 비산 각도를 제어해주도록 캡이 설치되는바, 이 캡은 바튬을 포위하도록 깔대기 형상으로 절곡형성되면서 전자총 방향의 원주부를 제외한 나머지 부위에 바튬이 관통할 수 있도록 다수의 작은 관통홀이 형성된 구조로 되어, 브라운관 외부에서 고주파를 발생시켜바튬을 가열하여 증바러시키면 바튬이 상기 캡의 관통홀을 통과하여 브라운관 내부로 균일하게 비산하게 되나, 이때 캡의 전자총쪽 원주부가 막혀 있으므로해서 이쪽 방향으로는 바튬이 비산되지 못함으로써 전자총에 바튬이 부착되는 것을 최소화하여 전자총의 동작중 아이크가 발생되거나, 또는 새도우마스크라던가 알류미늄 증착막에 과다한 바튬이 집중적으로 부착되는 것을 방지하여 화질의 저하를 방지할 수 있도록 되어있다.The present invention for achieving the above object, the cap is installed on the tip of the getter antenna to control the scattering angle of the lithium, this cap is bent in a funnel shape to surround the lithium while the circumferential portion in the direction of the electron gun It has a structure in which a number of small through-holes are formed to allow lithium to penetrate the remaining portions, and when the high-frequency is generated outside the CRT to heat and increase the battium, the BA passes through the through-hole of the cap and uniformly into the CRT. At this time, since the circumferential part of the electron gun side of the cap is blocked, the lithium cannot be scattered in this direction, thereby minimizing the attachment of lithium to the electron gun, causing the occurrence of ike during operation of the electron gun, or excessive shadow mask or aluminum deposition film. Prevents deterioration of image quality by preventing the adhesion of lithium It is supposed to be.
이하 본 고안을 첨부한 예시도면에 의거하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
브라운관(1)의 새도우마스크(2)를 지지하는 프레임(3)과 인너쉴드(4) 사이에 게터물질을 정착해 주도록된 게터안테나(5)가 고정되게 되는바, 이 게터안테나(5)의 한쪽 선단에는 퍼널(6)과 접촉하도록된 스프링(7)이 부착되고, 이 스프링(7) 반대쪽 게터안테나(5)상에는 게터물질이 바튬(8)이 채워진 용기(9)가 각각 고정되며, 이 용기(9)의 중앙에는 제2도에 도시된 바와같이 단면이 대칭이면서 상기 바튬(8)의 상부를 포위하도록 사다리꼴 모양으로 절곡시켜진 캡(10)이 고정되는 한편, 이 캡(10)의 전자총쪽 방향의 원주부에 형성된 경사면(10a)을 제외한 나머지 부위에는 상기 바튬(8)이 비산하면서 통과할 수 있도록 다수개의 관통홀(11)이 형성된 구조로 되어 있다.The getter antenna (5) is fixed between the frame (3) supporting the shadow mask (2) of the CRT (1) and the inner shield (4). The getter antenna (5) is fixed. One end is provided with a spring (7) in contact with the funnel (6), and on the opposite getter antenna (5), a container (9) filled with getter material (8) is fixed, respectively. In the center of the container 9 is fixed a cap 10, which is bent in a trapezoidal shape so as to be symmetrical in cross section and surrounds the upper part of the lithium 8, as shown in FIG. The remaining portions except the inclined surface 10a formed in the circumferential portion in the electron gun direction have a structure in which a plurality of through holes 11 are formed so that the lithium 8 can fly through.
다음은 이상과 같이 구성된 본 고안의 작용 효과에 대해 설명한다.The following describes the effects of the present invention configured as described above.
브라운관(1) 내부 프레임(3)과 인너쉴드(4)사이에 가조립된 게터안테나(5)를 매개로 본 고안 게터구조체를 정착하고서, 브라운관(1)을 배기시킨 다음 퍼널(6) 바깥쪽에 설치된 봄바딩코일에 고전압을 인가시켜주게 되면, 이 봄바딩코일과 게터안테나(5) 선단의 스프링(7) 사이에 고주파가 발생하게 되어 이 고주파가 상기 바튬(8)을 가열하여 증발 비산시켜주게 된다.The getter structure of the present invention is settled through a getter antenna (5) preassembled between the inner frame (3) and the inner shield (4) of the CRT, exhausting the CRT (1), and installed outside the funnel (6). When a high voltage is applied to the bombarding coil, a high frequency is generated between the spring binding coil and the spring 7 at the tip of the getter antenna 5, which causes the high frequency to heat and evaporate the lithium 8. .
이때 용기(9)로부터 비산되는 바튬(8)은 캡(10)에 의해 그 비산각도가 제어되게 되는바. 즉 바튬(8)을 감싸는 캡(10) 원주부의 전자총쪽 경사면(10a)에는 관통홀(11)이 형성되어 있지않아 바튬(8)이 전자총으로 비산하지 못하나, 캡(10)의 전자총쪽 경사면(10a)을 제외한 나머지 모든 부위에서는 관통홀(11)을 통해 바튬(9)이 균일하게 비산하게 된다. 이렇게 비산된 바튬(8)은 브라운관(1) 내부에 소량 남아있는 공기와 화합하여 브라운관 내부의 진공도를 더욱 높여주게되고, 상기 공기와 화합된 바튬화합물은 브라운관(1) 내벽과 인너쉴드(4)측벽에 골고루 달라붙게 된다.In this case, the scattering angle of the lithium 8 scattered from the container 9 is controlled by the cap 10. That is, since the through hole 11 is not formed in the electron gun-side inclined surface 10a of the circumferential portion of the cap 10 surrounding the lithium 8, the lithium 8 is not scattered by the electron gun, but the electron gun-side inclined surface of the cap 10 In all other portions except for 10a, the lithium 9 is uniformly scattered through the through hole 11. The scattered battium (8) is combined with a small amount of air remaining in the brown tube (1) to further increase the degree of vacuum inside the brown tube, and the compound of the air is combined with the air is the inner wall and inner shield (4) of the brown tube (1) It will stick evenly to the side walls.
이상과 같이 설명된 본 고안은, 게터안테나(5)의 선단에 설치된 용기(9)에 채워진 바튬(8)이 다수의 관통홀(11)이 형성된 캡(10)에 의해 둘러싸이게 되어 그 비산각도가 제어되는바. 특히 바튬(8)이 전자총쪽으로 비산되는 것을 최소화시켜 자자총의 동작중 아아크가 발생되는 현상을 방지해줌으로써 브라운관의 휘도 저하 미화상불량 현상을 방지해주는 효과가 있다.According to the present invention described above, the lithium 8 filled in the container 9 provided at the tip of the getter antenna 5 is surrounded by the cap 10 in which the plurality of through holes 11 are formed, and the scattering angle thereof is thus increased. Is controlled. In particular, by minimizing the scattering of the lithium (8) toward the electron gun to prevent the phenomenon of arcing during operation of the magnetic field gun has the effect of preventing the deterioration of the luminance degradation of the picture tube.
