11 : 인너쉴드 13 : 콘텍트스프링11: inner shield 13: contact spring

본 고안은 칼라 음극선관의 게터스프링 구조에 관한 것으로서, 좀더 구체적으로는 게터스프링에 콘텍트스프링을 일체화하여 원가를 절감함과 함께 조립작업을 간편하게 행할 수 있도록 한 것이다.The present invention relates to the getter spring structure of the color cathode ray tube, more specifically, to integrate the contact spring to the getter spring to reduce the cost and to simplify the assembly work.

일반적으로 칼라 음극선관은 주로 칼라 텔레비젼에 사용되어 영상신호(휘도신호와 칼라신호)에 의해 적(Red), 녹(Green), 청(Blue)색의 형광체를 발광시켜 칼라 화면을 재현하는 것으로서, 그 형태는 대략 판넬(Pannel)(1)과 후방으로 단면이 축소된 네크(Nedk)부(2)가 일체화되어 있는 펀넬(Funnel)(3)로 이루어져 구근형상(Bulb Form)의 외형을 갖고 있다.In general, color cathode ray tube is mainly used in color television to reproduce color screen by emitting red, green, and blue phosphors by video signal (luminance signal and color signal). Its shape consists of a panel (1) and a funnel (3) in which a neck portion (2) of which a cross section is reduced to the rear is integrated, and has a shape of a bulb form. .

이와같이 된 음극선관의 네크부(2)내에는 전자빔을 방출시킬 수 있도록 전자총(4)이 설치되어 있고, 펀넬(3)의 네크부(2) 전방 외주연에는 전자총(4)에서 방출된 전자빔을 수평 및 수직방향으로 편향시켜 주도록 편향 요크(5)가 설치되어 있으며, 상기 전자총(4)에는 아노드(Anode)(도시는 생략함)에 인가된 고압에 의해 음극 선관 내부를 고진공(10-7~10-8Torr)상태로 유지시키는데 사용되는 게터(Gatter)(6)를 지지하여 줌과 함께 상기 아노드에 인가된 고압을 전자총(4)으로 전달시켜 주는 게터스프링(Gatter Spring)(7)이 부착되어 있다.In the neck portion 2 of the cathode ray tube thus formed, an electron gun 4 is installed to emit an electron beam, and the electron beam emitted from the electron gun 4 is placed at the outer periphery of the neck portion 2 of the funnel 3. to give to the deflection in the horizontal and the vertical deflection yoke 5, and that is provided, the electron gun 4 is provided with an anode (anode) to the inside of the cathode-ray tube a high vacuum (10-7 by the high voltage applied to the (city is omitted) A getter spring (7) which supports a getter (Gatter) 6 which is used to maintain a ˜10 -8 Torr state and transmits the high pressure applied to the anode to the electron gun 4 together with the zoom. Is attached.

그리고 상기 네크부(2)의 대향측인 판넬(1) 내에는 전자총(4)에서 방출된 전자빔이 통과되도록 작은 구멍이 무수히 뚫린 새도우마스크(Shdow Mask)(8)가 프레임(9)에 고정된 상태로 지지되어 있고, 상기 판넬(1) 내측면에는 새도우마스크(8)를 통과한 전자빔이 부딪힐 때 화상이 맺혀지도록 형광체(10)가 도포되어 있으며, 상기 프레임(9)의 후방에는 전자총(4)에서 방출되는 전자빔이 지자계나 누설자계에 의해 진로가 변형되지 않도록 막아주는 인너쉴드(Inner Shield)(11)가 복수개의 판스프링(12)에 의해 고정되어 있고, 상기 프레임(9)에는 아노드에 인가된 고압을 새도우마스크(8)와 형광체(10)로 전달하여 주도록 콘텍트스프링(Contact Spring)(13)이 용접에 의해 고정되어 있다.In the panel 1 on the opposite side of the neck portion 2, a shadow mask 8 having a small number of small holes is fixed to the frame 9 so that the electron beam emitted from the electron gun 4 passes. It is supported in a state, and the phosphor 10 is coated on the inner surface of the panel 1 to form an image when the electron beam passing through the shadow mask 8 strikes, and the electron gun (behind the frame 9) An inner shield 11 which prevents the electron beam emitted from 4) from being deformed by the earth magnetic field or the leakage magnetic field is fixed by a plurality of leaf springs 12. The contact spring 13 is fixed by welding so as to transmit the high pressure applied to the node to the shadow mask 8 and the phosphor 10.

따라서 펀넬(3)의 외측둘레면 일측에 부착된 아노드로 고압을 인가하면 이 고압이 상기 펀넬의 내측둘레면에 도포된 흑연을 통해 음극선관 내부로 전달되므로 상기 음극선관 내부가 진공상태로 되는데, 이때 고압의 일부가 펀넬(3)의 내측둘레면에 도포된 흑연과 접촉되어 있는 게터스프링(7)을 통해 전자총(4)으로 전달됨과 함께 콘텍트스프링(13)을 통해 프레임(9)과 상기 프레임에 복수개의 판스프링(12)으로 고정된 인너쉴드(11)로 전달된다.Therefore, when a high pressure is applied to the anode attached to one side of the outer periphery of the funnel 3, the high pressure is transferred to the inside of the cathode ray tube through graphite applied to the inner periphery of the funnel, so that the inside of the cathode ray tube is in a vacuum state. At this time, a part of the high pressure is transferred to the electron gun 4 through the getter spring 7 which is in contact with the graphite coated on the inner circumferential surface of the funnel 3 and the frame 9 and the frame through the contact spring 13. The inner shield 11 is fixed to the plurality of leaf springs 12.

이와같이 하여 전자총(4)에 고압이 전달되면 상기 전자총이 작동되어 전자빔을 방출하고 이 방출된 전자빔은 펀넬(3)의 네크부(2) 전방 외주연에 설치된 편향요크(5)의 자계에 의해 수평 및 수직방향으로 편향되는데, 이때 콘텍트스프링(13)을 통해 고압을 전달받은 인너쉴드(11)가 편향된 상태로 계속 방출되는 전자빔의 지자계나 누설자게를 막아 상기 전자빔의 진로가 도중에 변형되지 않도록 한다.In this way, when a high pressure is transmitted to the electron gun 4, the electron gun is activated to emit an electron beam, and the emitted electron beam is horizontal by the magnetic field of the deflection yoke 5 installed at the outer periphery of the neck portion 2 of the funnel 3 in front. And it is deflected in the vertical direction, in this case, the inner shield 11 received the high pressure through the contact spring 13 to prevent the geomagnetic field or leakage of the electron beam continuously emitted in a deflected state so that the path of the electron beam is not deformed on the way.

한편 전자총(4)에서 방출된 전자빔은 프레임(9)에 고정된 새도우마스크(8)의 각 구멍을 통과하여 판넬(1)의 내측면에 도포된 형광체(10)에 부딪히므로 상기 형광체를 이루는 적, 녹, 청색이 발광하고 이에 따라 화상이 맺혀지는 것이다.On the other hand, the electron beam emitted from the electron gun 4 passes through each hole of the shadow mask 8 fixed to the frame 9 and hits the phosphor 10 coated on the inner surface of the panel 1 to form the phosphor. Red, green, and blue light emit light, thereby forming an image.

상기에서 고압을 전자총(4)으로 전달하여 주는 게터스프링(7)의 끝단에는 게터(6)가 지지되어 있는데, 상기 게터는 음극선관 조립공정시 상기 게터에 담긴 소이물질이 타면서 음극선관 내부의 잔류가스 및 이물질을 제거하여 상기 음극선관 내부를 고진공 시켜주도록 위함이다.The getter 6 is supported at the end of the getter spring 7, which transmits the high pressure to the electron gun 4, wherein the getter is burned by the foreign matter contained in the getter in the cathode ray tube assembly process. This is to remove the residual gas and foreign substances to high vacuum inside the cathode ray tube.

그러나 이와같은 일반적인 칼라 음극선관에 사용되는 종래의 콘텍트스프링은 케터스프링과 별도로 만들어져 있으므로 부품수가 증가됨과 함께 조립공수가 많아져 제작비가 상승됨은 물론 상기 콘텍트스프링을 용접할 때 발생되는 이물질에 의해 내전압 특성이 저하되는 문제점도 있었다.However, the conventional contact springs used in such a general color cathode ray tube are made separately from the ketter spring, so that the number of parts increases and the number of assembly operations increases, as well as the manufacturing cost, and withstand voltage characteristics due to foreign substances generated when welding the contact springs. There was also a problem of deterioration.

본 고안은 상기 문제점을 해결하기 위해 안출한 것으로서, 새도우마스크와 형광체에 고압을 전달하여 주는 콘텍트스프링의 끝단으로 전자총에 고압을 전달하여 주는 게터스프링에 일체화하여 부품수를 줄임에 따라 조립작업을 편리하게 행할 수 있도록 함과 함께 제작비도 저감시킬 수 있도록 하는데 그 목적이 있다.The present invention was devised to solve the above problems, and it is convenient to assemble by reducing the number of parts by integrating it with the getter spring which delivers high pressure to the electron gun to the end of the contact spring which delivers high pressure to the shadow mask and the phosphor. The purpose is to reduce the production cost as well as to be able to do so.

상기 목적을 달성하기 위한 본 고안 형태에 따르면 전자총에 부착된 게터스프링의 끝단으로 인너쉴드에 접촉되도록 콘텍트스프링을 일체 형성하여서 된 본 고안 칼라 음극선관의 게터스프링 구조가 제공된다.According to the present invention for achieving the above object there is provided a getter spring structure of the present invention color cathode ray tube formed by integrally forming a contact spring to contact the inner shield to the end of the getter spring attached to the electron gun.

이하 본 고안을 일실시예로 도시한 첨부된 도면 제3도 내지 제4도를 참고로 하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 to 4 of the accompanying drawings.

첨부도면 제3도는 본 고안 게터스프링을 갖는 칼라 음극선관의 전체 구조를 개략적으로 나타낸 단면도이고 제4도는 본 고안 게터스프링을 갖는 칼라 음극선관의 요부 구조를 나타낸 확대도로서, 전자총(4)에 부착되어 게터(6)를 지지함과 함께 고압을 상기 전자총(4)으로 전달하여 주는 게터스프링(7)의 끝단에 인너쉴드(11)에 접촉되도록 콘텍트스프링(13)을 일체 형성한 구조이다.FIG. 3 is a cross-sectional view schematically showing the overall structure of the color cathode ray tube having the getter spring of the present invention, and FIG. 4 is an enlarged view showing the main structure of the color cathode ray tube having the getter spring of the present invention, and is attached to the electron gun 4. The contact spring 13 is integrally formed to support the getter 6 and to contact the inner shield 11 at the end of the getter spring 7 which transmits the high pressure to the electron gun 4.

이와같이 구성된 본고안 케터스프링(7)을 조립할때는 상기 게터스프링의 끝단으로 일체 형성된 콘텍트스프링(13)이 인너쉴드(11)에 접촉되도록 하면된다.When assembling the subject matter keter spring 7 configured as described above, the contact spring 13 formed integrally with the end of the getter spring may be in contact with the inner shield 11.

한편 게터스프링(7)이 조립 완료된 상태에서 고압이 상기 게터스프링(7)을 통해 전자총(4)으로 전달될 때 이 고압은 상기 게터스프링(7)의 끝단에 일체 형성된 콘텍트스프링(13)을 통해 인너쉴드(11)로도 전달되고 계속해서 프레임(9)을 통해 새도우마스크(8)와 형광체(10)로 전달되므로 상기 전자총(4)에서 방출된 전자빔이 편향요크(5)에 의해 수평 및 수직방향으로 편향되어 새도우마스크(8)를 통과한 다음 형광체(10)에 부딪힘에 따라 상기 형광체의 발광에 의해 화상이 맺혀진다.On the other hand, when the high pressure is transmitted to the electron gun 4 through the getter spring 7 in the state where the getter spring 7 is assembled, the high pressure is formed through the contact spring 13 integrally formed at the end of the getter spring 7. It is also transmitted to the inner shield 11 and subsequently transmitted to the shadow mask 8 and the phosphor 10 through the frame 9 so that the electron beam emitted from the electron gun 4 is moved horizontally and vertically by the deflection yoke 5. As the light is deflected and passes through the shadow mask 8 and then hits the phosphor 10, an image is formed by light emission of the phosphor.

그러므로 본 고안은 게터스프링에 콘텍트스프링이 일체 형성되어 있어 부품수가 줄어들게 되므로 조립작업이 편리하게 됨과 함께 제작비가 절감되는 효과가 있다.Therefore, the present invention has a contact spring formed integrally with the getter spring, so that the number of parts is reduced, thereby making the assembly work more convenient and reducing the manufacturing cost.
