Abstract

본 발명은 함침형 음극 구조체 및 그 제조방법에 관한 것이다.The present invention relates to an impregnated anode structure and a method of manufacturing the same.

이는 전자방출물질이 함침된 음극기체와 그 내부에 삽입된 상기 음극기체의 이탈이 방지되도록 상단부가 소정각도 내향 절곡되며, 그 내주면에는 다수의 돌출부가 형성된 슬리이브와 상기 슬리이브의 돌출부상에 설치되어, 상기 음극기체의 하면을 지지하는 받침판을 구비한 것이다. 그리고 이의 제조방법은 상기 슬리이브의 상단부로부터 소정간격 이격된 그 하부 외주면을 외측으로 부터 가압하여 슬리이브 내주면으로 돌출되는 다수의 돌출부를 형성하고, 슬리이브의 내경과 같거나 약간 작은 직경의 받침판과 음극기체를 상기 슬리이브의 상단부로 부터 순차 삽입하여 상기 돌출부에 의해 지지되도록 하고, 슬리이브의 상단부 가장자리를 소정각도 내향 절곡하여 그 절곡된 가장자리에 의해 상기 음극기체의 이탈이 방지되도록 한다. 이러한 본 발명은, 열에 의한 음극기체의 특성변화를 근본적으로 방지할 수 있고, 동작온도를 낮출 수 있으며 빠른 화면 출화시간을 얻을 수 있도록 된 것이다.The upper end portion is bent inward at a predetermined angle to prevent the negative electrode gas impregnated with the electron-emitting material and the negative electrode gas inserted therein, and the inner circumferential surface is installed on a sleeve having a plurality of protrusions and a protrusion of the sleeve. And a supporting plate for supporting the lower surface of the cathode gas. In addition, the manufacturing method thereof forms a plurality of protrusions protruding from the outside by pressing the lower outer circumferential surface spaced apart from the upper end of the sleeve by a predetermined distance from the outside, and a support plate having a diameter equal to or smaller than the inner diameter of the sleeve The negative electrode gas is sequentially inserted from the upper end of the sleeve to be supported by the protrusion, and the upper edge of the sleeve is bent inward at a predetermined angle to prevent the negative electrode gas from being separated by the bent edge. This invention, it is possible to fundamentally prevent changes in the characteristics of the cathode gas due to heat, it is possible to lower the operating temperature and to obtain a fast screen fire time.
