본 고안은 칼라 브라운관용 전자총의 전극 연결체에 관한 것으로, 더욱 상세하게는 전자총에 전압을 인가시키기 위하여 각 전극에 접속되는 연결체를 정확하고 안정되게 고정토록 하여 불량율을 감소시키고 생산성을 향상시키도록 한 전자총의 전극 연결체에 관한 것이다.The present invention relates to an electrode connector of an electron gun for a color CRT tube, and more particularly, to fix the connector connected to each electrode accurately and stably in order to apply a voltage to the electron gun, so as to reduce a defective rate and improve productivity. It relates to an electrode connector of an electron gun.

일반적으로 칼라 브라운관용 전자총의 전극은 음극으로부터 방사되는 전자비임을 형광 스크린에 집속시키기 위하여 다수의 통과구멍이 일직선상으로 배열형성된 인-라인(in-line)방식을 채택하고 있으며, 다수의 전극을 각각 소정의 간격을 두고 순서대로 배열하여 비이드 글래스를 고온으로 용융시켜 다수의 전극을 압착하여 지지 고정하므로써 전극 조립체를 형성하고, 이 전극 조립체의 각 전극들이 각각의 기능을 할 수 있도록 전압을 인가시키기 위한 전압인가수단을 부여하고 있다.In general, the electrode of a color CRT electron gun adopts an in-line method in which a plurality of passing holes are arranged in a straight line to focus an electron beam emitted from a cathode on a fluorescent screen. They are arranged in order at a predetermined interval, and the beads glass is melted at a high temperature to compress and support a plurality of electrodes to form an electrode assembly, and a voltage is applied to each electrode of the electrode assembly to perform its respective function. The voltage application means is provided.

이러한 브라운관용 전자총은 각 전극의 길이와 직경, 그리고 각 전극간의 간격 및 각 전극에 인가되는 전압등이 브라운관의 동작을 좌우하는 특징적인 요소가 된다.The electron gun for the CRT becomes a characteristic element that determines the operation of the CRT due to the length and diameter of each electrode, the distance between each electrode, and the voltage applied to each electrode.

상기한 바와 같이 전자총의 특성으로 나타나는 요인중에서 전극에 전압을 인가시키기 위한 종래의 전극 연결체를 제 2 도 및 제 3 도에 나타낸다. 제 2 도는 종래의 전자총의 전극 연결체를 나타내기 위한 전극조립체의 개략적인 도면으로서, 음극(K)와 다수의 각 전극(G1-G8)이 소정의 간격을 두고 일열로 배열되어 1쌍의 비이드 글래스(B)에 지지 고정되어 있으며, 그 상측에는 실드컵(S)가 용접 고정되어 있다.2 and 3 show conventional electrode connectors for applying a voltage to electrodes among the factors exhibited by the characteristics of the electron gun as described above. FIG. 2 is a schematic diagram of an electrode assembly for showing an electrode connector of a conventional electron gun, in which a cathode (K) and a plurality of electrodes (G1-G8) are arranged in a row at a predetermined interval so that one pair of ratio It is supported by the fixed glass B, and the shield cup S is welded fixed on the upper side.

이와 같이 구성되는 전자총 구성체는 포커스 품위와 해상도가 향상된 선명한 화질을 제공하기 위하여 전극(G3)와 전극(G5), (G7)를 연결체(C)로 연결하여 동일한 전압을 인가하게 되는데 종래에는 제 3 도에 나타낸 바와 같이 전극(G)의 외주에 고리형상으로 돌출형성된 테두리부(1)의 소정위치에 종단이 "ㄱ"자상으로 절곡 형성된 연결체(C)를 접촉시켜 용접으로 고정 하였다.The electron gun construct configured as described above applies the same voltage by connecting the electrode G3, the electrodes G5, and G7 to the connector C in order to provide clear image quality with improved focus quality and resolution. As shown in FIG. 3, the end portion of the rim portion 1 protruded in a ring shape on the outer circumference of the electrode G was contacted and fixed by welding by connecting the connector C, which was bent in a "a" shape.

그러나, 상기한 연결체(C)와 접속되는 다른 전극(G3), (G5)는 상기한 연결체(C)와 접속되는 용접부위를 미리 절곡시킨 용접부(2)에 용접고정하였다. 그러나, 상기한 바와 같은 종래의 연결체(C)는 용접부(2)의 위치정밀도가 보장되지 않으면 전극과의 용접부위가 일정하지 않게 되어 매번 용접위치가 달라지므로 오히려 번거롭게 되기 때문에 작업 생산성의 저하와 불량율증가의 한 요인이 된다는 문제가 있다.However, the other electrodes G3 and G5 connected to the above-mentioned connecting body C were welded and fixed to the welded part 2 in which the welded area to be connected to the above-mentioned connecting body C was bent in advance. However, in the conventional connection body C as described above, if the positional accuracy of the welding portion 2 is not guaranteed, the welding position with the electrode becomes uneven and the welding position is changed every time. There is a problem that it becomes a factor of increasing the defective rate.

본 고안은 상기한 바와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로, 본 고안의 목적은 전극과 연결체간의 용접고정을 안정되고 일정하게 하여 작업 생산성을 향상시키고, 불량율을 최소화할 수 있는 전자총의 전극 연결체를 제공하는데 있다. 상기한 바와 같은 목적을 달성하기 위하여 본 고안은 연결체의 선단에 절곡부가 절곡형성되어 전극의 테두리부에 뚫려진 관통구내로 삽입 고정되는 전자총의 전극 연결체를 제공한다.The present invention is devised to solve the problems of the prior art as described above, the object of the present invention is to stabilize the welding between the electrode and the connector is stable and constant to improve the work productivity, the electron gun that can minimize the defective rate To provide an electrode connector. In order to achieve the object as described above, the present invention provides an electrode connector of the electron gun that is bent into the bent end of the connector to be inserted into the through hole drilled in the edge of the electrode.

또한, 본 고안은 상기한 절곡부가 ""자상으로 절곡 형성된 전자총의 전극 연결체를 제공한다. 이하, 본 고안의 바람직한 실시예를 첨부된 도면 제 1 도에 따라서 더욱 상세하게 설명한다.In addition, the present invention is the above-mentioned bent portion " "Providing an electrode connector of a magnetically bent electron gun. Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

The through hole 4 is drilled inside the expansion part 3. A bent portion 6 is bent at the tip of the connecting body 5 inserted into the through hole 4. The bent portion 6 may be any shape as long as it is inserted into the through hole 4, but the state inserted into the through hole 4 should be stable. "Shape is preferred.

상기한 연결체(5)의 하측은 종래의 구성과 동일한 구성으로 절곡 형성되어 다른 전극과 용접 접속이 가능하게 되어 있다. 도면에서 미설명부호(7)은 전극지지구이고, (8)은 비임통과구멍이다.The lower side of the above-mentioned connecting body 5 is bent and formed in the same configuration as the conventional configuration, and welding connection with other electrodes is possible. In the figure, reference numeral 7 denotes an electrode support, and 8 denotes a non-passing hole.

상기한 바와 같이 구성되는 본 고안은 관통구(4)내에 연결체(5)의 절곡부(6)을 삽입한 후 스포트 용접 등의 방법으로 용접하여 고정하게 된다. 이렇게 하면 매 전자총마다 연결체(5)의 용접위치가 일정하게 되며 용접시의 연결체(5)의 유동 등에 의한 용접작업의 불안정이 해소되고 현저하게 불량율이 저하됨과 아울러 작업 생산성을 향상시키고, 확실하고 정확한 용접으로 인하여 포커스 품위와 해상도가 향상된 선명한 화질을 얻을 있는 이점이 있다.According to the present invention configured as described above, the bent portion 6 of the connecting body 5 is inserted into the through hole 4 and then welded and fixed by a method such as spot welding. This makes the welding position of the connecting body 5 constant for every electron gun. The instability of the welding work due to the flow of the connecting body 5 at the time of welding is eliminated, the defective rate is remarkably reduced, and the work productivity is improved. Due to the precise welding, there is an advantage of obtaining a clear picture quality with improved focus quality and resolution.
