본 고안은 음극선관용 전자총의 지지체에 관한 것으로서, 상세하게는 전자총의 실드컵에 고정되어 음극선관의 네크부에 탄력 접촉됨으로서 전자총을 네크부의 정중앙에 위치하는 지지체에 관한 것이다.The present invention relates to a support for an electron gun for a cathode ray tube, and more particularly, to a support for fixing an electron gun to a neck portion of a cathode ray tube so as to be elastically contacted with a neck portion of a cathode ray tube.

제 1 도에 도시된 바와같이 전자총(G)의 실드컵(S)에 용접고정되어 네크부(N)의 내측면에 탄력 접촉됨으로써 상기 전자총(G)을 네크부(N)의 정중앙에 위치되게 하는 일종의 스페이성린 전자총의 지지체(10a)는, 제 2 도에 도시된 바와 같이 실드컵(S)측면에 다수 용접고정되는 것으로서, 이를 각각 컷팅(Cutting) 및 포밍(Forming)된 후에 개별적으로 전기 용접기에 의해 부착되는 것이다. 이러한 지지체(10a)는 일반적으로 하나의 전자총에 보통 3개정도가 부착되는데, 각각 개별적으로 용접고정되는 까닭으로 서로 용접상태가 다른 문제점이 있다. 이에 의하면 전자총이 네크부의 정중앙에 위치되지 못하게 되므로 전자빔의 전행방향이 크게 수정되지 않으면 안되는 문제점이 발생된다.As shown in FIG. 1, the welding gun is fixed to the shield cup S of the electron gun G to elastically contact the inner surface of the neck part N so that the electron gun G is positioned at the center of the neck part N. FIG. As shown in FIG. 2, the support 10a of the spherical lean electron gun is welded and fixed to the shield cup S side, and each of them is individually cut after being cut and formed. It is attached by a welding machine. Generally, the support 10a is generally attached to three electron guns in one electron gun, and each weld is fixed to each other. According to this, since the electron gun cannot be located at the center of the neck part, the traveling direction of the electron beam must be largely modified.

본 고안은 이러한 문제점을 개선하여 전자총의 안치불량에 따르는 음극선관의 품질저하를 억제할 수 있는 음극선관용 전자총의 지지체를 제공함에 그 목적이 있다.The object of the present invention is to provide a support for an electron gun for a cathode ray tube that can suppress such a deterioration in quality of the cathode ray tube due to the settling of the electron gun.

상기의 목적을 달성하기 위하여 본 고안은, 음극선관용 전자총의 실드컵에 고정되는 것으로, 네크부의 내측면에 탄력적으로 접촉되는 복수개 탄력편을 구비한 음극선관용 전자총의 지지체에 있어서, 상기 다수 접촉부를 상기 실드컵의 바닥면에 용접고정될 수 있는 크기의 직경을 가진 도너츠형 몸체의 둘레에 방사상으로 형성한 점에 그 특징이 있다.In order to achieve the above object, the present invention is to be fixed to the shield cup of the cathode ray tube electron gun, the support of the cathode ray tube electron gun having a plurality of elastic pieces in elastic contact with the inner surface of the neck portion, wherein the majority of the contact portion It is characterized in that it is formed radially around a donut-shaped body having a diameter of a size that can be welded to the bottom of the shield cup.

이하 첨부된 도면에 예시된 본 고안의 한 실시예를 상세히 설명한다.Hereinafter, an embodiment of the present invention illustrated in the accompanying drawings will be described in detail.

전자총의 실드컵(S)과 거의 같은 직경의 도너츠형 몸체(11b)둘레에 세개의 탄력편(12b)이 방사상으로 형성되어 동일 방향으로 절곡되는바, 각 탄력편(12b)의 선단부에는 만곡면을 갖는 접촉부(13b)가 형성된다.Three elastic pieces 12b are radially formed around the donut-shaped body 11b having a diameter substantially the same as that of the shield cup S of the electron gun, and are bent in the same direction. A curved surface is provided at the tip of each elastic piece 12b. The contact part 13b which has is formed.

그리고 상기 몸체(11b)의 내경의 크기는 가능한 최대화하여 빔경로에 대하여 간섭을 일으키지 않도록 한다. 도면중 미설명된 부호 A는 상기 실드컵(S)의 바닥면에 상기 도너츠형 몸체(11b)를 사이에 두고 용접결합되는 애노우드 전극이며, B는 바이드글래스이다.The inner diameter of the body 11b is maximized as much as possible so as not to cause interference with the beam path. Reference numeral A, which is not described in the drawings, is an anode electrode welded to the bottom surface of the shield cup S with the donut-shaped body 11b therebetween, and B is a bead glass.

이상과 같은 구조의 본 고안의 실시예는 제 4 도에 도시된 바와 같이 결합되는데, 실드컵(S)의 바닥면에 상기 몸체(11b), 애노우드전극(A)의 순으로 저항용접되는 것이다. 이와같이 되면 몸체(11b)와 일체로 형성되는 탄력편(12b)에의 크기와 탄력이 거의 동일하기 때문에 음극선관의 네크부에 설치되었을때에 전자통의 쏠림이 방지된다. 더우기 상기 탄력편(12b)이 상기 실드컵(S)의 바닥면으로부터 연장되는 관계로 실드컵(S)의 개구부로부터 얼마 돌출되지 않더라도 충분한 길이를 얻을 수 있게 되는데 결론적으로 전자총의 전체 길이가 축소되게 된다.Embodiment of the present invention of the structure as described above is coupled as shown in Figure 4, the resistance is welded in the order of the body 11b, the anode electrode (A) to the bottom surface of the shield cup (S). . In this case, since the size and elasticity of the elastic piece 12b integrally formed with the body 11b are almost the same, the tipping of the electron tube is prevented when it is installed in the neck portion of the cathode ray tube. Furthermore, since the elastic piece 12b extends from the bottom surface of the shield cup S, a sufficient length can be obtained even if it does not protrude from the opening of the shield cup S. Consequently, the entire length of the electron gun is reduced. do.

그리고 부품의 제조조립하는 공정에 있어서도 하나의 단일품으로 가공되며 전자총의 실드컵(S)에 일시에 고정이 되므로 작업성이 크게 향상되게 된다.In the process of manufacturing and assembling the part, it is processed into a single piece and fixed to the shield cup S of the electron gun at a time, thereby greatly improving workability.

이상에서와 같이 본 고안은 음극선관의 품질을 안정시킬 뿐만 아니라 제조가공비를 제저시켜 제조공정을 단축하여 제품의 생산성 향상을 기하는 특징이 있는 것이다.As described above, the present invention is characterized by improving the productivity of the product by shortening the manufacturing process by stabilizing the quality of the cathode ray tube as well as reducing the manufacturing process cost.
