본 고안은 음극선관용 전자총의 전극구조체에 관한 것으로서 보다 상세하게는 전극을 비이드 그래스에 융착시킬때 압력을 분산시켜 변형을 최소화할 수 있는 음극선관용 전자총의 전극구조체에 관한 것이다.The present invention relates to an electrode structure of an electron gun for a cathode ray tube, and more particularly, to an electrode structure of an electron gun for a cathode ray tube that can minimize deformation by dispersing pressure when welding an electrode to bead grass.
음극으로부터 방사되는 전자비임을 통과시키기 위한 다수의 전자비임통과구멍이 일직선상에 뚫려진 인라인형 방식을 채택하고 있으며, 특히 전자비임을 컬러음극선관의 스크린에 집속시키는 주렌즈부를 구성하는 전극들은 외부의 영향을 받지 않도록 하기 위하여 컵형태의 전극을 채용하고 있다.Adopted the in-line type in which a plurality of electron beam through holes are passed in a straight line to pass the electron beam emitted from the cathode. In particular, the electrodes constituting the main lens unit for focusing the electron beam on the screen of the color cathode ray tube are external In order to avoid the influence of the cup-shaped electrode is adopted.
제3도는 다단집속형 전자렌즈를 형성하는 인라인형 전자총전극의 측단면도로서, 음극지지구(A)에는 3개의 음극(B)가 동일수평선상으로 지지되어 있으며, 이 음극(B)내에 장치된 히터(도시생략)에 의해 가열되어 전자 비임을 방출토록 되어 있다.3 is a side cross-sectional view of an inline electron gun electrode forming a multi-stage focused electron lens, wherein three cathodes B are supported on the same horizontal line in the cathode support A, and the cathode B is provided in the cathode B; It is heated by a heater (not shown) to emit an electron beam.
그리고, 음극(B)와 근접되어 상기한 전자비임을 제어하는 제1전극(C)가 배치되어 있고, 이 제1전극(C)와 대향되어 상기 전자비임을 가속하는 제2전극(D)가 배치되어 있다.In addition, a first electrode C is disposed close to the cathode B to control the electron beam, and a second electrode D facing the first electrode C to accelerate the electron beam is disposed. It is arranged.
제2전극(D)와 대향되어 상기한 전자비임을 집속시키는 렌즈부가 제3전극(E)와 제4전극(F),로 이루어져 순차적으로 배치되어 있다.The lens unit, which faces the second electrode D and focuses the above-described electron beam, is sequentially formed of the third electrode E and the fourth electrode F.
그리고, 상기한 모든 전극들은 전극 외주에 직교상으로 형성된 플랜지(H1), (H2), (H3)가 비이드 글래스(I)에 매립되어 고정 설치되는 구성으로 되어 있다.In addition, all the electrodes described above have a configuration in which flanges H1, H2, and H3 orthogonally formed on the outer periphery of the electrode are embedded in and fixed to the bead glass I.
제4도는 제3도의 렌즈부를 형성하는 제3전극(E)와, 제4전극(F), 와 같이 컵형태를 이루는 전극의 평면도로서, 바깥면에 형성된 플랜지(H3), (H4)가 형성되어 있다.FIG. 4 is a plan view of the third electrode E forming the lens portion of FIG. 3 and the cup-shaped electrode like the fourth electrode F, and the flanges H3 and H4 formed on the outer surface are formed. It is.
이러한 플랜지(H3), (H4)는 비이드 글래스(I)에 고정되어 각 전극간의 간격을 유지시켜줌과 아울러 융착시 압력을 전극의 각부로 분산시켜 전극의 변형을 최소화하게 된다.These flanges (H3), (H4) is fixed to the bead glass (I) to maintain the distance between the electrodes, and to minimize the deformation of the electrode by dispersing the pressure during welding to each part of the electrode.
그러나, 전극의 크기가 커지거나 전극 부재의 두께가 얇으면 플랜지부의 크기가 커져 제한된 공간내에 수납하는 것이 실제적으로 어렵게 된다.However, when the size of the electrode is large or the thickness of the electrode member is thin, the size of the flange portion is large, and it becomes practically difficult to store in the limited space.
한편, 미국 특허 제4595858호 에서는 상기한 문제점을 해소하고자 전극의 벽면을 골을 형성하여 힘을 분산시키도록 하는 전극을 제안하고 있으나, 골이 전극에 나란히 설치되어 있기 때문에 힘의 분산효과를 크게 기대할 수 없다.On the other hand, US Patent No. 4,595,858 proposes an electrode to disperse the force by forming a valley on the wall of the electrode to solve the above problem, but since the valley is installed side by side on the electrode, a great effect of the force dispersion is expected. Can't.
본 고안은 상기한 바와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 전극 융착시의 압력을 분산시켜 전극의 변형을 방지함으로써 각 전극간의 경사나 편심에 의한 이상현상을 방지할 수 있는 음극선관용 전자총의 전극 구조체를 제공하는 데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to prevent the abnormal phenomenon due to the inclination or eccentricity between the electrodes by dispersing the pressure by dispersing the pressure during electrode welding An electrode structure of an electron gun for cathode ray tubes can be provided.
상기한 바와같은 목적을 달성하기 위하여 본 고안은, 컵형 전극의 장변측 플랜지상에 아치형의 돌출부를 형성시켜 융착시 압력분산을 할 수 있는 음극선관용 전자총의 전극 구조체를 제공한다.In order to achieve the above object, the present invention provides an electrode structure of an electron gun for a cathode ray tube which can form an arcuate protrusion on the flange of the long side of the cup-shaped electrode and can perform pressure dispersion during welding.
제1도는 본 고안의 전극 구조체의 사시도이고, 제2도는 본 고안의 전극 구조체의 측면도로서, 부호(1)은 전극본체를 나타낸다.1 is a perspective view of an electrode structure of the present invention, and FIG. 2 is a side view of the electrode structure of the present invention, and reference numeral 1 denotes an electrode body.
전극본체(1)은 수직부(1a)와 직교상으로 연장된 수평부(1b)상에 적,녹,청의 전자비임이 통과하는 구멍(2), (3), (4)가 뚫어져 있으며 수직부(1a)의 아래쪽에는 소정형상의 매립부(5)가 돌출 형성된 플랜지(6)이 전체 주변부에 형성되어 있다.The electrode body 1 has holes (2), (3), and (4) through which the electron beams of red, green, and blue pass through the horizontal portion (1b) perpendicular to the vertical portion (1a). The flange 6 in which the predetermined | prescribed buried part 5 protruded is formed in the whole periphery part below the part 1a.
그리고, 상기한 플랜지(6)의 장변측상에는 아치형상의 돌출부(7)이 돌출 형성되어 그 안쪽면이 수직부(1a)에 일체로 부착되어 있다.On the long side of the flange 6, an arcuate projecting portion 7 protrudes, and its inner surface is integrally attached to the vertical portion 1a.
이와 같이,구성되는 본 고안의 전극구조체는, 비이드 글래스에 플랜지(6)의 매립부(5)가 융착될 때 발생되는 압력이 돌출부(7)에 전달되어 분산되기 때문에 플랜지(6)의 변형을 방지할 수 있다.As described above, the electrode structure of the present invention, which is constructed, is deformed in the flange 6 because the pressure generated when the buried portion 5 of the flange 6 is fused to the bead glass is transmitted to and distributed to the protrusion 7. Can be prevented.
더우기 돌출부(7)이 매립부(5)에 근접되는 위치의 플랜지(6)상에 형성되어 있기 때문에 두께가 두꺼워져 융착시 받는 압력에 변형되지 않고, 압력분산이 이루어진다.Furthermore, since the protrusion 7 is formed on the flange 6 at a position close to the buried portion 5, the thickness becomes thick and does not deform to the pressure received at the time of fusion, thereby achieving pressure dispersion.
이와같이 전극을 비이드 글래스에 융착할때 그 압력을 분산 흡수함으로써 전극의 변형을 방지하여 전극간의 간격변화를 억제시킴과 동시에 각전극간의 경사나 편심을 방지할수 있게 되어 전자총의 조림정도를 향상시킬 수 있으며, 전자총의 조립오차에 기인하는 상퍼짐현상을 방지할 수 있다.In this way, when welding the electrode to the bead glass by dispersing and absorbing the pressure, it prevents the deformation of the electrode to suppress the change of the gap between the electrodes and prevents the inclination or eccentricity between the electrodes. It is possible to prevent the spreading phenomenon caused by the assembly error of the electron gun.
