본 고안은 칼라음극선관에 인가된 고압을 색선별전극 및 형광막증의 Al막에 도통시키는 컨택트스프링(CONTACT SPRING)에 관련된 것으로서, 특히 컨택트스프링과 후레임과의 조립시에 용접공정을 없애고, 조립성을 향상시켜 생산성 향상과 원가절감이 가능하도록 한 칼라음극선관의 컨택트스프링에 관한 것이다.The present invention relates to a contact spring for conducting a high pressure applied to a color cathode ray tube to an Al film of a color screening electrode and a fluorescent film. In particular, it eliminates a welding process when assembling a contact spring and a frame, The present invention relates to a contact spring of a color cathode ray tube which can improve productivity and reduce cost.
종래의 칼라음극선관은 제1도에 도시된 바와 같이, 판넬(2)의 내면에 적, 녹, 청(R, G, B)의 형광물질을 도포하여 형광막(11)을 형성하고, 그 상부에 진공중착장치를 이용하여 알루미늄으로 이루어지는 알루미늄막을 형성하였다.In the conventional color cathode ray tube, as shown in FIG. 1, the fluorescent film 11 is formed by applying red, green, and blue (R, G, B) fluorescent materials to the inner surface of the panel 2, and An aluminum film made of aluminum was formed on the top using a vacuum deposition apparatus.
그리고 색선별 전극(SHADOW MASK, 6)은 후레임부(7)의 용접에 의하여 고정된 상태에서 후레임부측면에 부착된 후레임 고정 스프링(13)을 이용하여 판넬 핀(12)에 결합시켜 판넬(2) 내부 측면에 장착하였다.In addition, the color selection electrode (SHADOW MASK) 6 is coupled to the panel pin 12 by using a frame fixing spring 13 attached to the side of the frame in a state of being fixed by welding of the frame 7. ) Mounted on the inner side.
그리고 훠넬부(FUNNEL, 3)는 프리트 그라스(FRIT GLASS, 10)로서 판넬 실면에 융착시켰고, 상기 융착시 음극선관내부의 진공은 10-7Torr 정도가 적당하였다.And the funnel portion (FUNNEL, 3) was fused to the panel surface as frit glass (FRIT GLASS, 10), the vacuum inside the cathode ray tube during the fusion was about 10 -7 Torr is appropriate.
또한 컨택트스프링(1)은 전자총(4)에서 발생한 전자빔을 용이하게 형광막(11)에 도달시키기 위하여 애노드 캐비터(ANODE CAVITY, 14)를 통해 인가된 고압을 후레임부(7)의 색선별 전극 및 형광막 상부의 알루미늄막에 도통시켜 양극막을 형성하게 하는 도통매체로서, 제2도에 도시된 바와 같이 후레임부(7)에 용접공정에 의하여 부착하였다.In addition, the contact spring 1 receives the high voltage applied through the anode cavity 14 in order to easily reach the fluorescent film 11 from the electron beam generated by the electron gun 4. And a conductive medium for conducting the aluminum film on the upper portion of the fluorescent film to form an anode film, which was attached to the frame portion 7 by a welding process as shown in FIG.
그러나, 컨택트스프링(1)을 후레임부(7)에 용접하는 공정은 단순히 용접만을 위하여 별도의 공정이 필요하며, 용접이 여러차례 걸쳐 이루어지므로써 후레임에 변형이 발생하거나 작업이 매우 번거로운 불편이 있었고, 용접이 잘못된 경우에는 후레임에서 분리된 컨택트스프링은 재사용이 불가능한 문제점이 있다.However, the process of welding the contact spring (1) to the frame portion (7) simply requires a separate process only for welding, and because the welding is made several times, the deformation occurs in the frame or the work is very cumbersome, If the welding is wrong, there is a problem that the contact spring separated from the frame cannot be reused.
따라서 본 고안은 컨택트스프링과 후레임을 용접수단에 의하지 아니하면서도 용이하게 결합할 수 있는 결합 수단을 제공함에 그 목적이 있다.Therefore, an object of the present invention is to provide a coupling means that can be easily coupled to the contact spring and frame not by a welding means.
본 고안은 이를 위하여 후레임에 통공을 가지는 돌출부를 형성하고, 컨택트스프링의 하단부에는 상기 돌출부에 걸려서 컨택트스프링을 상기 돌출부에 결합하도록 하는 걸림턱을 형성함과 동시에 상기 걸림턱에 탄력을 부여하는 탄력수단을 구비토록 한 것으로서 이를 첨부한 도면에 도시된 본 고안의 실시예에 따라 상술하면 다음과 같다.The present invention forms a projection having a hole in the frame for this purpose, and at the lower end of the contact spring to form a latching jaw to engage the contact spring to the contact to the projection and at the same time to give elasticity to the locking jaw When described in detail according to an embodiment of the present invention shown in the accompanying drawings as having as follows.
후레임(7)에는, 제3도에 도시된 바와 같이, 컨택트스프링(1)의 걸림턱(17, 17')을 끼워넣기 위한 소정공간인 통공(15)을 가지는 돌출부(9)을 형성한다.As shown in FIG. 3, the frame 7 is provided with a protrusion 9 having a through hole 15, which is a predetermined space for fitting the locking projections 17 and 17 'of the contact spring 1.
컨택트스프링(1)의 하단부인 기본판(19)의 단부에는, 제4도에 도시된 바와 같이 상기 통공(15)에 끼워지는 걸림턱(17)을 형성하고, 상기 걸림턱(17)과 대향하면서 소정간격만큼 격리된 또다른 걸림턱(17')을 구비하여 양 걸림턱(17, 17')은 탄력부(16)로 연결한다.At the end of the base plate 19, which is the lower end of the contact spring 1, as shown in FIG. 4, a locking jaw 17 fitted into the through hole 15 is formed, and is opposed to the locking jaw 17. While having another locking jaw (17 ') is isolated by a predetermined interval while the two locking jaw (17, 17') is connected to the elastic portion (16).
상기 탄력부(16)는 양 걸림턱(17, 17')의 간격이 탄력을 가진 상태로 변화하기 위한 탄력을 양 걸림턱(17, 17')에 부여한다.The elastic part 16 gives elasticity to both the locking projections 17 and 17 'to change the interval between the two locking projections 17 and 17' to have elasticity.
그리고 걸림턱(17')의 일측면에는 상기 기본판(19)과 대향하고, 양컬림턱(17, 17')의 간격을 확대시키기 위한 누름판(18)을 고정한다.In addition, the pressing plate 18 is fixed to one side of the locking jaw 17 'to face the base plate 19 and to enlarge the gap between the two collar jaws 17 and 17'.
따라서, 컨택트스프링(1)을 후레임(7)에 결합하고자 하는 경우 누름판(18)과 기본판(19)을 누르면 걸림턱(17, 17')의 간격은, 제5도에 도시된 바와 같이, a에서 b로 확대된다.Therefore, when the contact spring 1 is to be coupled to the frame 7, when the pressing plate 18 and the base plate 19 are pressed, the interval between the locking jaws 17 and 17 'is shown in FIG. Zooms from a to b
이어서 양 걸림틱(17, 17')의 간격이 확대된 상태에서 양 걸림턱(17, 17')을 통공(15)에 끼운후 기본판(19)과 누름판(18)에 가한 힘을 제거하면 양 걸림턱(17, 17')은 탄력부(16)의 탄력에 의해 원래 위치로 복귀하여 그 간격은 a가 된다.Subsequently, when the distance between the two locking ticks 17 and 17 'is expanded, the two locking jaws 17 and 17' are inserted into the through hole 15, and then the force applied to the base plate 19 and the pressing plate 18 is removed. Both locking jaws 17 and 17 'are returned to their original positions by the elasticity of the elastic portion 16, and the interval becomes a.
이로인해 컨택트스프링(1)과 후레임(7)은 걸림턱(17, 17')이 돌출부(9)에 걸려 이탈하지 않음과 동시에 탄력부(16)의 탄력에 의해 탄력적으로 상호 결합한다.As a result, the contact spring 1 and the frame 7 are elastically coupled to each other by the elasticity of the elastic part 16 while the locking jaws 17 and 17 'are not caught by the protrusion 9 and are not separated.
이와같은 본 고안은 컨택트스프링과 후레임부를 용접에 의하지 아니하면서도 손쉽게 조립할 수 있어 생산성을 향상시킴을 물론 컨택트스프링의 손실을 방지하여 원가를 절감할 수 있는 작용효과가 있다.The present invention has the effect of reducing the cost of the contact spring and frame parts can be easily assembled without welding to improve productivity as well as to prevent loss of the contact spring.
