본 고안은 음극 선관용 전자총 구체에 관한 것으로 특히 발브 콘텍트 스프링의 구조를 개선하여 전자총의 조립성을 좋게할 뿐만 아니라 신뢰성을 향상시키도록한 전자총 구체에 관한 것이다.The present invention relates to an electron gun sphere for a cathode ray tube, and more particularly to an electron gun sphere for improving the structure of the valve contact spring to improve the assembly of the electron gun as well as to improve the reliability.
종래 음극 선관용 전자총의 발브 콘텍트 스프링은 발브의 네크부에 삽입시킬시 제5격자의 플랜지면 상측에 일정간격을 띄운다음 저항 용접을 시키므로 발브 콘텍트 스프링의 탄성력이 약하게 되어 마이크로 포닉의 불량이 발생되었고 상기 용접위치가 작업자의 감각에 의해 임의로 결정되므로 정확하고 일관된 작업을 할 수 없게 되어 불량이 발생되어 제품의 신뢰성이 떨어지는 문제점이 발생되었다.When the valve contact spring of the conventional cathode ray tube gun gun is inserted into the neck portion of the valve, resistance contact welding is performed after spaced a certain distance above the flange surface of the fifth grid, so that the elastic force of the valve contact spring is weakened, resulting in a microphonic defect. Since the welding position is arbitrarily determined by the operator's sense, it is impossible to perform accurate and consistent work, which causes a problem inferior in reliability of the product.
따라서 상기한 문제점을 개선시키기 위해 본 고안은 발브 콘텍트 스프링의 절단부를 굴곡되게 형성하여 탄성력을 일정하게 유지시켜 작업 능률을 향상시키고자 한 것이다.Therefore, in order to improve the above problems, the present invention is to form a cut portion of the valve contact spring to bend to maintain a constant elastic force to improve the work efficiency.
종래의 음극 선관용 전자총의 구성을 첨부된 도면에 따라 설명하면, 음극 선관용 전자총은 전자총의 외부에 전자 코일이나 자석을 설치하여 전자 비임의 집속을 행하게 하는 전자 집속형 전자총과 전자총에 집속전자렌즈를 구비하고 정전집속을 행하게 하는 정전집속형으로 크게 대별되는 데, 상기 정전집속형 전자총은 음극, 제1격자전극, 제2격자전극, 제3격자전극, 제4격자전극 제5격자전극을 갖추고 있으며 제3격자전극과 제5격자전극에 동일한 전압을 인가하는 유니포텐셜형 전자총과 이와는 달리 전자비임의 촛점 조정을 행하게 하는 바이포텐셜 전자총이 있는바, 제1도는 상기 유니포텐셜 전자총을 나타낸 것으로써 전자를 방사하는 음극(1)과 제1격자전극(2), 제2격자전극(3), 제3격자전극(4), 제4격자전극(5), 제5격자전극(6) 및 상기한 것들을 일정하게 배설하도록 하는 절연 지지봉(7)과 발브의 내면에 칠해진 내장 흑연(9)을 통해 인가된 고압을 상기 제5격자전극(6)에 전해주며 제2도에 도시한 네크부(10)에서 일정 위치에 있도록 지탱해주는 역할을 하는 발브 콘텍트 스프링(8)으로 구성되어 있는데, 상기 발브 콘텍트 스프링(8)은 제2도와 같이 제5격자전극(6)의 플랜지면(11)상측에 일정간격(ℓ)만큼 띄운 다음 저항 용접을 한다.Referring to the configuration of a conventional cathode ray tube electron gun according to the accompanying drawings, the cathode ray tube electron gun is an electron focusing electron gun and an electron focusing electron lens to install an electron coil or a magnet outside the electron gun to focus the electron beam It is roughly divided into electrostatic focusing type to perform electrostatic focusing, the electrostatic focusing electron gun is equipped with a cathode, a first grid electrode, a second grid electrode, a third grid electrode, the fourth grid electrode fifth grid electrode And a bipotential electron gun that applies the same voltage to the third and fifth grid electrodes, and a bipotential electron gun that allows the electron beam to be focused. FIG. 1 shows the universal electron gun. The cathode (1) and the first lattice electrode (2), the second lattice electrode (3), the third lattice electrode (4), the fourth lattice electrode (5), the fifth lattice electrode (6) and the above-mentioned Keep things constant The high pressure applied through the insulating support rod 7 and the embedded graphite 9 painted on the inner surface of the valve is transmitted to the fifth lattice electrode 6 and is positioned at the neck portion 10 shown in FIG. It is composed of a valve contact spring (8) that serves to support the, the valve contact spring (8) is a predetermined interval (ℓ) above the flange surface 11 of the fifth grid electrode (6) as shown in FIG. Float and then do resistance welding.
상기와 같이 용접된 발브 콘텍트 스프링(8)은 제3도와 같이 네크부(10)에 삽입되어 봉지공정에서 삽입되는데, 이때 발브 콘텍트 스프링(8)은 네크부(10)에 밀착되어 탄성을 가지게 되어 전자총 구체를 일정 위치에 고정시켜 주게 되며 발브의 내면에 칠해진 내장흑연(9)을 통해 인가된 고압을 제5격자전극(6)에 전달시켜 주는 역할을 하게 된다.The valve contact spring 8 welded as described above is inserted into the neck portion 10 and inserted in the encapsulation process as shown in FIG. 3, wherein the valve contact spring 8 is in close contact with the neck portion 10 to have elasticity. The electron gun sphere is fixed at a predetermined position and serves to transfer the high pressure applied through the embedded graphite 9 painted on the inner surface of the valve to the fifth grid electrode 6.
상기에 따라 발브 콘텍트 스프링(8)은 네크부(10)에 삽입될때 변형되기도 하며 용접위치의 일정간격(ℓ)에 따라 탄성력이 변형되기도 한다.According to the above, the valve contact spring 8 may be deformed when inserted into the neck portion 10, and the elastic force may be deformed according to a predetermined distance ℓ of the welding position.
제4도는 용접위치에 따른 탄성력의 변화 선도를 나타낸 것으로 탄성력이 Ts 이하가 될 경우 마이크로 포닉의 불량이 발생되어 용접위치는 ℓs 이상이 되어야 하나 작업자의 감각에 의해서 용접 위치를 찾게 되므로 정확하고 일관된 작업을 할 수가 없어 불량이 발생되는 문제점이 발생되었다.4 shows the change of the elastic force according to the welding position. When the elastic force is less than Ts, the microphonic defect is generated and the welding position should be ℓs or more. I can not do that a problem occurs that a defect occurs.
따라서 상기한 문제점을 개선시킨 본 고안의 기술 구성을 제4도와 제5도에 따라 설명하면, 발브 콘텍트 스프링(8)의 저항편(12)를 제4도의 용접위치에 따른 탄성력의 변화선도에서 탄성력이 가장 안정되는 길이인 ℓ1만큼의 길이를 갖도록 하여 굴곡성형시켜 제5격자전극(6)의 플랜지면(11)에 맞추어 놓고 용접을 한다.Therefore, the technical configuration of the present invention, which improves the above-mentioned problems, will be described with reference to FIG. 4 and FIG. 5, in which the resistance piece 12 of the valve contact spring 8 is changed in the elastic force according to the welding position of FIG. This is the most stable length by the length of 1, bend-molded to match the flange surface 11 of the fifth grid electrode (6) and welded.
따라서 본 고안은 발브 콘텍트 스프링(8)의 저항편(12)를 탄성력이 가장 안정되는 길이(ℓ1)만큼 굴곡 형성시켜 용접시키므로 발브 콘텍트 스프링의 작업성을 향상시켜 생산성을 높이며 또한 탄성력을 일정하게 유지시켜 마이크로 포닉의 불량을 방지시켜 제품에 대한 신뢰도를 증진시킬 수 있는 효과를 제공한다.Therefore, the present invention bends and welds the resistance piece 12 of the valve contact spring 8 by the length (l 1 ) in which the elastic force is the most stable, thereby improving the workability of the valve contact spring, thereby improving productivity and making the elastic force constant. It provides the effect of improving the reliability of the product by preventing the failure of the microphonic.
