본 고안은 전자총 구체 특히 전자총구체를 지지하기 위해 실드컵에 용접하여 고정하는 전자총 구체에 관한 것이다. 일반적으로 칼라 수상관은 제1도에 나타낸것처럼, 패널부(1)와 훤넬부(2) 및 네크부(3)로 구성되는 그라스발브(4)를 가지고 이 그라스발브(4)의 내외 면에는 내부도전막(5)과 외부도전막(6)이 설치되어 있다.The present invention relates to an electron gun sphere, in particular an electron gun sphere fixed by welding to a shield cup to support the electron gun sphere. In general, the collar water tube has a glass valve (4) consisting of a panel portion (1), a channel portion (2) and a neck portion (3), as shown in FIG. The inner conductive film 5 and the outer conductive film 6 are provided.
상기 내부 도전막은 네크부(3)의 내면까지 연장되어 있고, 훤넬부(2)의 일부에 절연피막(7)에 의해 격리된 가속 전극단자(8)에 전기적으로 접속된다.The inner conductive film extends to the inner surface of the neck portion 3 and is electrically connected to the acceleration electrode terminal 8 isolated by the insulating film 7 on a part of the channel portion 2.
상기 네크부(3)에는 전자총구체(9)가 내장되어 있고, 이 구체에는 제2도에 나타낸것처럼 주전 자렌즈 형성용 고압측전극(12)(13)과 주전자 렌즈 형성용 저압측전극(14)과 각 전극을 일체로 지지하는 비드그라스(15)와 실드컵(11)과 실드컵(11)의 주위에 배치되어 전자총 구체를 내크부(3)내벽에 고정하는 3본의 발브스페이서(16)와 역시 실드컵의 주위에는 훤넬부(2)의 내벽을 따라 놓여 있는 개터서포터(17)가 고정되어 있고, 그 선단에는 유도가열에 적당한 형상으로 된 링(Ring)상의 게터(18)가 고정되어 있다.The neck portion 3 is equipped with an electron muzzle 9, and in this sphere, as shown in FIG. 2, the high pressure side electrodes 12 and 13 for forming the main magnet lens and the low pressure side electrodes 14 for forming the kettle lens. ) And three valve spacers 16 arranged around the bead glass 15, the shield cup 11, and the shield cup 11 to integrally support each electrode to fix the electron gun sphere to the inner wall of the inner portion 3. ) And also a gutter supporter 17, which is placed along the inner wall of the channel portion 2, is fixed around the shield cup, and a getter 18 on a ring of a shape suitable for induction heating is fixed at its tip. It is.
이렇게 구성된 전자총 구체(9)는 스템부(도시되지 않음)를 관통하는 리드를 매개로 신호를 공급하고, 또한 훤넬부(2)의 내벽에 피복된 내부 도전막(5)에 접하는 3본의 발브스페이서(16)와 게터서포터(17)를 매개로서 고전압을 공급하고 있는 것이다. 그러나, 상기 구성에 대한 전자총 구체는 제4도에 그 단면을 나타낸 것처럼 거이 동일한 탄성력(F)을 가지는 3개의 발브스페이서(16)와 다소적은 탄성력(Fg)을 가지는 게터서포터(17)가 실드컵(11)의 주위를 적당한 간격을 가지고 배치되어 있어서, 이를 탄성력의 합성력은 "0"가 되어 네크부(3)내의 중심에 전자총 구체를 보지하도록 한다.The electron gun sphere 9 thus configured supplies three signals through a lead passing through the stem portion (not shown) and contacts the inner conductive film 5 coated on the inner wall of the channel portion 2. The high voltage is supplied via the spacer 16 and the getter supporter 17. However, in the electron gun sphere for the above configuration, as shown in the cross section in FIG. The periphery of (11) is arrange | positioned at an appropriate space | interval, and this synthesize | combination force of an elastic force becomes "0" so that an electron gun sphere may be hold | maintained in the center in the neck part 3.
그렇지만 제5도 및 제6도에 나타낸것처럼 실드컵(11)과 발브스페이서(16)는 선접촉을 하게되므로 용접작업시 취급부주의에 의해 제6도(a)처럼 잘못용접이 될 경우 발브스페이서의 탄성력(F)은 힘이 작용 방향이 바뀌게 된다.However, as shown in FIGS. 5 and 6, the shield cup 11 and the valve spacer 16 are in contact with each other. Therefore, if the welding is performed incorrectly as shown in FIG. The elastic force (F) is the direction in which the force acts.
따라서 힘의 합성력은 "0"가 되지 않고 제6도(c)처럼 여분의 힘(Fs)이 남게 되어 전자총 구체가 관축 방향보다 어긋나게 되는 결점이 있는 것이다.Therefore, the combined force of the force does not become "0" and the extra force Fs remains as shown in FIG. 6 (c), which causes the electron gun sphere to deviate from the direction of the tube axis.
그러므로, 실드컵(11)에 발브 스페이서나 게터서포터(17)를 용접 고정할때의 작업성도 나쁘게 되고, 또한 제6도(a)(b)와 같이 용접 고정될 경우 힘의 합성력은 Fs만큼 남게 되어 전자총 구체를 관축 방향에서 어긋나게 하므로서 칼라 수상관의 수직방향 라스터쉬프트(Vertical Raster Shift : VRS) 및 수평방향 라스터쉬프트(Horizontal Raster shift : HRS)가 크게 되어 결국 포커스 특성에 열화를 가져오는 문제점이 있는 것이다.Therefore, the workability at the time of welding and fixing the valve spacer or the getter supporter 17 to the shield cup 11 also becomes poor, and when the welding is fixed as shown in FIG. Problem in that the vertical raster shift (VRS) and horizontal raster shift (HRS) of the color receiving tube become large as the electron gun sphere is displaced from the tube axis direction, resulting in deterioration in focus characteristics. Is there.
따라서 본 고안은 종래의 문제점을 해결하여 작업 조건에 관계없이 전자총 구체를 관축상에 정확하게 고정하는 것이 가능한 전자총 고체를 제공하고져 하는 것으로 이를 첨부 도면과 함께 상세하게 설명하면 다음과 같다.Therefore, the present invention is to solve the conventional problems to provide an electron gun solid that can be fixed to the electron gun sphere accurately on the tube axis irrespective of the working conditions to be described in detail with the accompanying drawings as follows.
제7도(a)(b)는 본 고안에 따른 발브 스페이서의 측면도 및 단면도인 것으로, 발브 스페이서(16)의 외면을 실드컵(11)의 용접부(16b)의 외경에 대응하는 곡률(R)로 형성하는 것이다. 이러한 구성으로 이루어진 본 고안은 실드컵(11)과의 발브 스페이서(16)의 용접부(16b)를 실드컵(11)의 외경(R)과 같은 크기로 가공하므로서 용접 고정될 때 곡률(R)로 인해 면접촉을 하게 된다.7 (a) and (b) are side views and cross-sectional views of the valve spacer according to the present invention. The outer surface of the valve spacer 16 corresponds to the outer diameter of the welded portion 16b of the shield cup 11. To form. According to the present invention having the above configuration, the welding portion 16b of the valve spacer 16 with the shield cup 11 is processed to the same size as the outer diameter R of the shield cup 11 so as to have a curvature R when the welding is fixed. This is due to the surface contact.
따라서 종래보다 확실하게 전자총 구체를 지지할수 있으며 힘의 방향도 바뀜없이 힘의 합성력은 항상 "0"가 되어 불량율이 현저하게 줄어들어 생산성 향상이 이루어지고 치숭 및 정도 관리도 용이하게 할수 있는 이점이 있는 것이다.Therefore, it is possible to support the electron gun sphere more reliably than before, and the force of the force does not change, the combined force of the force is always 0 ", so that the defect rate is remarkably reduced, resulting in improved productivity and easier management of precision and precision. .
