본 고안은 전자총의 컨버전스컵 구조에 관한 것으로서, 컨버전스컵의 제작을 간편하게 하여 잡업효율을 향상하고 벌브스페이서를 컨버전스컵과 일체로 형성하여 벌브스페이서의 부착 위치불량을 제거하기 위하여 안출한 것이다.The present invention relates to the structure of the convergence cup of the electron gun, to simplify the production of the convergence cup to improve the working efficiency and to form a bulb spacer integrally with the convergence cup to devise to remove the defective placement of the bulb spacer.

일반적으로 전자총의 상단에 설치되는 컨버전스컵은 네크내부에 장착되어, 캐소드와 각 전극의 통과공을 통과한 전자빔이 브라운관의 형광체와 새도우마스크에 랜딩이 잘되도록 전자빔을 집속하는 역할을 담당하고, 상기 컨버전스컵의 외주면에 용접 고정된 수개의 벌브스페이서는 브라운관의 펀넬(FUNNEL)내부에 도포된 흑연 재질의 도전막과 탄접되어 전자총에 양전기를 제공함과 아울러 전자총의 중심을 잡아주어 발출된 전자빔이 형광체와 새도우마스크에 정확하게 랜딩되는 것을 도와준다.In general, the convergence cup installed at the top of the electron gun is mounted inside the neck, and serves to focus the electron beam so that the electron beam passing through the cathode and the through hole of each electrode is landing on the phosphor and shadow mask of the CRT. Several bulb spacers welded and fixed to the outer circumferential surface of the convergence cup are in contact with the conductive film made of graphite coated inside the FUNEL of the CRT to provide positive electric charge to the electron gun and to hold the center of the electron gun. It helps to land correctly on the shadow mask.

그러나 종래의 컨버전스컵(10)은 도면 제4도에 도시한 바와같이 수개의 통과공(13)을 구비한 하부판(12)이 주벽부(11)와 일체로 형성한 다음, 상기 주벽부(11)의 외주면 적소에 수개의 벌브스페이서(20)를 용접 고정하여서 된 것으로써, 상기 컨버전스컵(10)의 주벽부(10)와 통과공(13)을 가진 하부판(12)을 일체로 형성하기 위해서는 고도의 기술 및 여러장치를 필요로 하고, 이에 따른 작업효율이 매우 저하되며, 또한 주벽부(11)의 외주면에 벌브스페이서(20)를 용접 고정하는 과정에서 컨버전스컵(10)에 대한 각 벌브스페이서(20)의 부착위치가 일정하게 부착되지 않는 상태로 네크(미도시)내부에 전자총(1)을 결합 고정하면 캐소드 및 전극을 지난 전자빔이 컨버전스컵(10)을 통과하면서, 형광체 및 새도우마스크와의 중심축이 일치하지 않아 수상관의 선명도가 저하되는 문제점이 있었다.However, in the conventional convergence cup 10, as shown in FIG. 4, the lower plate 12 having several passage holes 13 is integrally formed with the main wall portion 11, and then the main wall portion 11 is formed. In order to integrally form the lower plate 12 having the circumferential wall portion 10 and the through hole 13 of the convergence cup 10 by welding several bulb spacers 20 in place on the outer circumferential surface of It requires a high technology and a variety of devices, the work efficiency is very low, and each bulb spacer for the convergence cup 10 in the process of welding and fixing the bulb spacer 20 to the outer peripheral surface of the main wall portion 11 When the attachment position of the 20 is fixed to the inside of the neck (not shown) in a state where the attachment position is not fixed, the electron beam passing through the cathode and the electrode passes through the convergence cup 10, and the phosphor and the shadow mask Of the tube is inconsistent with the central axis of There was a problem.

본 고안은 이와같은 문제점들을 해결하기 위하여 컨버전스컵의 주벽부를 형성하는 판재에 벌브스페이서를 일체로 형성한 다음, 통과공이 천공된 하부판에 용접 결합하므로써, 그 성형과정이 용이하게 작업효율이 높아지고, 벌브스페이서가 적정 위치에 정확하게 형성되므로 수상관이 선명도를 높은 정도로 유지할 수 있도록 한 전자총의 컨버전스컵 구조를 제공함에 있다.In order to solve these problems, the present invention forms a bulb spacer integrally on the plate forming the main wall of the convergence cup, and then welds to the lower plate where the through-holes are perforated, so that the molding process becomes easier and the work efficiency is increased. The spacer is formed precisely in the proper position, and thus provides a convergence cup structure of the electron gun, which allows the receiving tube to maintain a high degree of sharpness.

따라서 이러한 목적을 달성하기 위하여 본 고안은 전자총의 전방에 위치하고, 벌브스페이서가 구비된, 컨버전스컵에 있어서 소정크기의 판재에 적정 간격을 두고 벌브스페이서를 수개 포밍한 다음, 이 판재를 원통형상으로 형성하여 용접 결합하고, 그 개구된 하부에 통과공이 형성된 하부판을 용접 결합하여서 된 특징이 있다.Therefore, in order to achieve the above object, the present invention is located in front of the electron gun, and in the convergence cup equipped with a bulb spacer, several bulb spacers are formed at appropriate intervals on a plate of a predetermined size, and then the plate is formed into a cylindrical shape. By welding, and joining the lower plate formed with a through hole in the lower portion of the opening.

이하, 본 고안의 실시예에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail based on the embodiment of the present invention as follows.

제1도는 본 고안의 컨버전스컵의 분해사시도로써 가상선과 같은 판재(11)의 적소에 수개의 벌브스페이서(20)의 벽부를 절개하여 형성한 다음, 이를 도면과 같이 원통으로 구성하여 두 끝단을 용접결합하고, 상기 벌브스페이서(20)를 외향 돌출토록 하여 네크와의 결합시 네크의 내벽에 밀착탄접되도록 하는 한편, 개구된 하부에 관통공(13)이 소정 천공된 하부판(12)을 용접고정하여서 된 것이다.FIG. 1 is an exploded perspective view of the convergence cup of the present invention, formed by cutting the wall portions of several bulb spacers 20 in place of a plate 11 such as an imaginary line, and then constructing a cylinder as shown in the drawing to weld both ends. By coupling the bulb spacer 20 to the outward so as to be in close contact with the inner wall of the neck when engaged with the neck, while welding the fixing the lower plate 12 with a predetermined through hole 13 in the lower opening It is.

제2도는 컨버전스컵(10)이 전자총(1) 상단에 설치된 것을 도시한 것이고, 제3도는 본 고안인 컨버전스컵(10)을 측면에서 절개한 것을 도시한 것이다.2 is a view showing that the convergence cup 10 is installed on the upper side of the electron gun 1, and FIG. 3 is a side cutaway view of the convergence cup 10 of the present invention.

이와같이 본 고안은 컨버전스컵(10)을 제작할 때, 벌브스페이서(20)가 포밍 형성된 판재(11)를 원통형상으로 용접결합하여 통과공(13)이 천공된 하부판(12)에 용접토록 하므로써, 작업공정이 매우 단순하여 생산성이 증가하고, 벌브스페이서(20)의 부착위치 불량으로 인한 브라운관의 불량을 완전 제거하도록 된 매우 신규 유용한 고안이다.In this way, the present invention, when manufacturing the convergence cup 10, the bulb spacer 20 is welded to the formed plate member 11 formed in a cylindrical shape by welding the through-hole 13 to the perforated lower plate 12, work The process is very simple and the productivity is increased, it is a very novel and useful design to completely eliminate the defects of the CRT due to the poor attachment position of the bulb spacer 20.
