본 고안은 칼라 수상관용 전자총 구체의 플랜지에 관한 것으로서, 특히 접속할때 일어나는 외력을 감소시키고 조립시에 생기는 전극의 충격을 흡수하도록한 칼라 수상관용 전자총 구체의 플랜지에 관한 것이다.The present invention relates to a flange of an electron gun sphere for a collar receiving tube, and more particularly, to a flange of an electron gun sphere for a collar receiving tube to reduce external force occurring during connection and to absorb an impact of an electrode generated during assembly.

종래의 칼라 수상관용 전자총의 G3(3), G4(4) 전극은 본체(11')의 저면에 3개의 전자빔 통과공(12')을 형성하고 상부의 양측으로 플랜지(5')을 구성하여 이를 전자총 구체(9)에 설치하는데 전자총 구체(9)에는 제 2 도에서와 같이 복수의 전자총 전극 조립체의 마운트 서포터(8')와 복수의 음극 조립체(7)가 있으며 이들과 대행하는 곳에 전자빔 방향으로 G1 전극(1'), G2 전극(2'), G3 전극(3'), G4 전극(4')을 순차배치하여 각 전극을 지지하는 두 개의 절연물 비이드그라스(10')사이에서 융착 고정하고 동시에 이들 사이에서 소정의 전극 간격을 유지하도록하며 전자총 전극 구체의 조립 작업 간이화, 조립 정밀도 향상 혹은 칼라 음극 선관의 전자총을 싸고 있는 유리관 목부분의 직경을 적게하여 전자총 전극 구체의 점유체적 축소화를 실현하는 수단으로서 전기적, 구조적으로 공통이고 각 전자비임 통로에 실질적으로 개별의 전자렌지를 형성하는 집적 전극을 구비한 전자총 전극 구체가 일반적이다.The G3 (3) and G4 (4) electrodes of the conventional color water tube electron gun are formed with three electron beam through holes 12 'at the bottom of the main body 11', and the flanges 5 'are formed at both sides of the upper part. It is installed in the electron gun sphere 9, which has a mount supporter 8 'and a plurality of cathode assemblies 7 of the plurality of electron gun electrode assemblies, as shown in FIG. G1 electrode 1 ', G2 electrode 2', G3 electrode 3 'and G4 electrode 4' are sequentially arranged to weld between two insulator beads 10 'supporting each electrode. To maintain the predetermined electrode spacing between them, and to simplify the assembly work of the electron gun electrode sphere, to improve the assembly precision, or to reduce the occupancy reduction of the electron electrode sphere by reducing the diameter of the neck of the glass tube surrounding the electron gun of the color cathode ray tube. Electrical and structural as a means of realization In general, electron gun electrode spheres having an integrated electrode which are common to and form a substantially separate microwave oven in each electron beam passage are common.

이와같이 구성된 종래의 칼라 수상관용 전자총의 작용 효과를 설명하면 다음과 같다.The operation and effect of the conventional color water tube electron gun constructed as described above are as follows.

고온으로 용융된 비이드그라스(10')에 다수의 그리드 전극(1', 2', 3', 4')을 소정의 간격으로 융착할 때 각 그리드 전극(1', 2', 3', 4')에서는 조립공정중 기계에서 발생된 충격이 순간적으로 가해지고 비이드그라스(10')의 열변형에 의해 불규칙한 확장이 전자총 축방향 또는 축에 수직인 방향으로 미세한 치수 변동을 발생시키며 전자총 품종을 구별하기 위해 비이드그라스(10')의 색상에 따라 용융점을 900℃-1200℃로 하여 산포가 크기 때문에 각 그리드 전극(1', 2', 3', 4')의 양쪽 끝의 비이드그라스(10')삽입부의 응력이 서로 달라서 미세한 치수 변동이 일어난다.When the plurality of grid electrodes 1 ', 2', 3 ', 4' are fused at predetermined intervals to the beadgrass 10 'melted at a high temperature, the grid electrodes 1', 2 ', 3', In 4 '), the impact generated by the machine during the assembly process is instantaneously applied, and the irregular expansion is caused by the thermal deformation of the beadgrass 10', causing a slight dimensional change in the direction of the electron gun axial or perpendicular to the axis. In order to distinguish between the bead glass 10 'according to the color of the melting point of 900 ℃-1200 ℃ because of the large dispersion, bead at both ends of each grid electrode (1', 2 ', 3', 4 ') The stresses of the inserts of the glass 10 'are different from each other, resulting in minute dimensional variations.

이와 같이 종래에는 비이드그라스에 각 그리드 전극을 융착시킬때 기계적인 충격이 각 그리드 전극에 미치기 때문에 미세한 변형이 발생하고 전자총 제조 공정중 G4 전극의 경우는 많은 접촉이 가해지기 때문에 G3 전극과 평행을 이루지 못하고 어긋나는 문제점이 있었다.As described above, when the grid electrodes are fused to beadgrass, mechanical shocks are applied to the grid electrodes so that minute deformation occurs, and in the case of the electron gun manufacturing process, G4 electrodes have a lot of contacts, so they are parallel to the G3 electrodes. There was a problem that could not be achieved.

따라서 본 고안은 이러한 문제점을 개선하고자 안출한 것으로서 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Therefore, the present invention is described in detail based on the accompanying drawings as having been devised to improve such a problem as follows.

칼라 수상관용 전자총의 G3(3), G4(4) 전극은 본체(11)의 저면에 3개의 전자빔 통과공(12)을 형성하고 상부의 양측으로 플랜지(5)를 구성하여 이를 전자총 구체(9)에 설치하는데 전자총 구체(9)에는 복수의 전자총 전극 조립체의 마운트서포터(8)와 복수의 음극 조립체(7)가 있으며 이들과 대향하는 곳에 전자 비임 방향으로 G1 전극(1), G2 전극(2), G3 전극(3), G4 전극(4)을 순차 배치하여 각 전극을 지지하는 두개의 절연물 비이드그라스(10) 사이에서 융착 고정하고 동시에 이들 사이에서 소정의 전극 간격을 유지한 것에 있어서, G3 전극(3), G4 전극(4)의 플랜지(5)에 ""형 홈(5a)을 형성한다.The G3 (3) and G4 (4) electrodes of the color water tube electron gun form three electron beam through holes 12 on the bottom surface of the main body 11, and the flanges 5 are formed on both sides of the upper portion to form the electron gun sphere (9). The electron gun sphere (9) has a mount supporter (8) and a plurality of cathode assemblies (7) of the plurality of electron gun electrode assemblies, and the G1 electrode (1) and the G2 electrode (2) in the direction of the electron beam are opposed to them. ), The G3 electrode 3 and the G4 electrode 4 are sequentially arranged to be fusion-fixed between two insulator beads 10 supporting the electrodes, and at the same time to maintain a predetermined electrode gap therebetween. The flange 3 of the G3 electrode 3 and the G4 electrode 4 " &Quot; formed grooves 5a.

이와 같이 구성된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

플랜지(5)에 ""형 홈(5a)을 형성한 G3 전극(3), G4 전극(4)을 비이드그라스(10)에 소정의 간격으로 융착하면 각 그리드 전극(1, 2, 3, 4)에 전자총 조립 공정중 순간적으로 가해지는 기계적 충격과 비이드그라스(10)에 생기는 열변형에 의한 축방향 또는 축에 수직 방향으로의 미세한 치수 변동 및 용접에 의한 외력이 발생하더라도 G3 전극(3), G4 전극(4)의 플랜지(5)에 형성한 홈(5a)이 흡수하므로서 G3 전극(3), G4 전극(4) 간격의 평행을 유지할 수 있다.On flange (5) When the G3 electrode 3 and the G4 electrode 4 on which the grooves 5a are formed are fused to the beadgrass 10 at predetermined intervals, an electron gun assembly process is performed on the grid electrodes 1, 2, 3, and 4. G3 electrode (3), G4 electrode (4) even if minute dimensional fluctuations in the axial direction or perpendicular to the axis due to mechanical shock applied to the beadgrass (10) and external force due to welding are generated. By absorbing the groove 5a formed in the flange 5 of), parallelism between the G3 electrode 3 and the G4 electrode 4 can be maintained.

상술한 바와 같이 본 고안은 전자총 전극의 플랜지에 홈을 형성하여 접속할 때 일어나는 외력 및 조립에서 생기는 전극의 충격을 흡수하는 효과가 있다.As described above, the present invention has the effect of absorbing the external force generated when the groove is connected to the flange of the electron gun electrode and the impact of the electrode generated in the assembly.
