본 고안은 전자총용 히이터 지지체에 관한 것이다.The present invention relates to a heater support for an electron gun.
전자총의 캐소오드는 히이터에 의해 가열되어 전자를 방출하는 열전자방출 물질을 포함하고 있으며, 히이터로 열전자방출물질을 가열하는 방식에 따라 필라멘트 상에 직접 열전자방출물질을 도포하여 열전달이 되게 하는 직열형 캐소오드와, 필라멘트를 슬리이브 내측에 위치시키고 이 슬리이브 상에 열전자방출물질을 도포하여 열전달이 되게 하는 방열형 캐소오드로 나누어진다.The cathode of the electron gun includes a hot electron-emitting material that is heated by a heater to emit electrons, and is a direct-heat casing that applies heat electron-emitting material directly onto the filament for heat transfer according to a method of heating the hot electron-emitting material with the heater. It is divided into an anode and a heat dissipating cathode which places the filament inside the sleeve and heat transfers by applying a hot electron emission material on the sleeve.
전자의 직열형 캐소오드는 동작시간이 빠른 이점이 있지만 필라멘트에 도포된 열전자방출물질이 불안정하여 사용수명이 짧고 또 제작이 어렵기 때문에 부부분의 텔레비젼은 방열형 캐소오드를 사용하고 있는 실정이다. 방열형 캐소오드에서 슬리이브와 히이터는 각각 비이드글라스에 매립되는 지지체에 의해 소정위치로 배열된다.The direct thermal cathode of the electron has the advantage of fast operating time, but because of the unstable hot electron emission material applied to the filament is short and the life is difficult to manufacture a couple of TVs are using a heat radiation cathode. In the heat dissipating cathode, the sleeve and the heater are each arranged in a predetermined position by a support embedded in the bead glass.
히이터 지지체의 일반적인 구조는 제 2도에 도시한 바와 같이 2쌍의 매립간(A)마다 지지간(B)을 용접연결시킨 구성으로 되어 있고, 일부 지지간(B)은 복잡하게 절곡된 구조로 되는 바, 이는 지지간(B)에 단자역활을 겸비시켜서 필라멘트(F)로 소정의 전압을 인가할 수 있게 하기 위함이다.As shown in FIG. 2, the general structure of the heater support has a structure in which the support bar B is welded to each of the two pairs of buried rods A, and some of the support bars B are complexly bent. This is to combine the terminal role between the support bar (B) to be able to apply a predetermined voltage to the filament (F).
그러나 상술한 히이터 지지체는 그 제조에 많은 부품을 필요로 하고, 더구나 이들 부품은 서로 다른 형태로 밴딩형성되는데다 여기에 히이터를 결선하기도 상당히 어려워서 생산성 향상과는 다소 거리가 먼 구조를 갖고 있다는 단점을 보여준다.However, the heater support described above requires a large number of parts for its manufacture, and furthermore, these parts are banded in different shapes, and it is also difficult to connect the heaters, which has a structure far from productivity. Shows.
본 고안의 목적은 상술한 종래의 히이터 지지체와는 달리 밴딩이 복잡하지 않고 간결하게 형성된 전자총용 히이터 지지체를 제공함에 있다.It is an object of the present invention to provide a heater support for an electron gun, in which banding is not complicated and is simply formed, unlike the above-described conventional heater support.
상기 목적에 따라 본 고안은 서로 대향하는 1쌍의 평상상 단자판에 매립간을 직교방향으로 연결하고, 전기한 단자판의 사이로 다수의 절연체를 일정 간격마다 개재시킴과 아울러 단자판의 일축으로 다소 좁은 폭을 이루는 접속부를 상호 어긋나는 위치로 연장 형성시켜 구성됨을 특징으로 한다.In accordance with the above object, the present invention connects the buried in the orthogonal direction to a pair of flat terminal boards facing each other, interposes a plurality of insulators at regular intervals between the electrical terminal boards, and also has a rather narrow width as one axis of the terminal board. It is characterized in that the connecting portion is formed by extending to form a mutually shifting position.
이하 본 고안의 바람직한 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도에 도시한 바와 같이 본 고안 지지체는 서로 대향하는 1상의 평상판 단자판(1)에 매립간(2)을 직교방향으로 연결하고, 또 전기한 단자판(1)의 사이에는 다수의 절연체(3)를 일정 간격마다 개재시켜 양단자판(1)이 서로 대치되게 한 구성으로 되어 있다.As shown in FIG. 1, the support according to the present invention connects the buried interposer 2 to the orthogonal direction with the one-phase flat plate terminal plates 1 facing each other, and between the terminal plates 1, which are described above, a plurality of insulators ( Both terminals 1 are replaced by interposing 3) at regular intervals.
상기한 단자판(1)은 일측에 절곡연장부(4)를 보유하고 타측에는 스텝에서 연장되는 리이드(L)와 용접되기 위한 접속부(5)를 형성하고 있으며, 이들 접속부(5)는 용접작업이 용이하게 되도록 상호 어긋난 위치로 대향되게 형성하는 것이 좋다.The terminal plate 1 has a bent extension portion 4 on one side and a connection portion 5 for welding with the lead L extending in the step on the other side, and these connection portions 5 are welded. It is good to form it so that it may oppose mutually shifted position so that it may become easy.
또 단자판(1) 사이에 다수 개재되는 절연체(3)로는 결정화글라스나 세라믹을 사용할 수 있다.Crystallized glass or ceramics can be used as the insulator 3 interposed between the terminal plates 1 in a large number.
이들 절연체(3)에 의해 양 단자판(1)은 일정 간격을 두고 상호 대치된 상태로 일체화된다.By these insulators 3, both terminal plates 1 are integrated in a state where they are opposed to each other at regular intervals.
이와 같이 구성된 본 고안 지지체에 의하면, 각각의 단자판(1)은 필라멘트(F)의 어느 한쪽과 용접 연결되어 전기적으로 병렬 접속시키게 되고, 또한 매립간(2)은 통상의 비이드그라스에 매립되어 단자판(1)을 지지시켜줌으로써, 종래의 히이터 지지체와 동일하게 필라멘트(F)가 슬리이브 내측으로 위치되게 하는 것이나, 본 고안 지지체는 평판상으로 된 1쌍의 단자판(1) 사이를 절연체(3)로 일정 간격 대치되게 한 구조이므로 부품수가 줄어 들고, 또 복잡한 밴딩을 요하지 않으면서도 스템 리이드(L)와의 전기적 결선이나 필라멘트(F)의 용접 연결이 현저하게 용이해져서 생산성의 향상을 도모할 수 있는 실용성을 갖추게 되는 것이다.According to the inventive support structure configured as described above, each terminal plate 1 is connected to one of the filaments F by welding and electrically connected in parallel, and the buried interposer 2 is embedded in a conventional bead glass and the terminal plate. By supporting (1), the filament (F) is positioned inside the sleeve in the same way as the conventional heater support, but the support of the present invention supports the insulator (3) between the pair of terminal plates (1) in the form of a plate. As the structure is replaced at regular intervals, the number of parts is reduced, and the electrical connection to the stem lead (L) and the welding connection of the filament (F) are remarkably easy without requiring complicated banding, thereby improving productivity. Will be equipped.
