摘要： A pre-assembled vacuum switch tube having a clearance between a stationary electrode rod and end plate is firstly prepared by forming an enlarged diameter part in the stationary electrode rod at a position where the rod extends from the end plate to the outside of the vacuum envelope and by arranging at least one piece of plate-like brazing material having a flat surface. The pre-assembled vacuum switch tube is put into a vacuum furnace; the interior of the vacuum switch tube is evacuated through the clearance; temperature in the furnace is elevated to melt the brazing material thereby causing the descending of the enlarged diameter part due to the dead weight of the stationary electrode rod and the vacuum switch tube is sealed by bonding of the end plate and the rod. Alternatively, the clearance is formed in such a manner that a supporting member having a through hole into which the enlarged diameter part of the stationary electrode rod is inserted is placed on the end plate and at least one piece of plate-like brazing material is arranged between the supporting member and the enlarged diameter part of the stationary electrode rod.
摘要翻译：首先，通过在固定电极棒上形成一个放大的直径部分，其中杆从端板延伸到真空外壳的外部的位置，准备了一个在固定电极杆和端板之间具有间隙的预组装的真空开关管并且通过布置具有平坦表面的至少一块板状钎焊材料。将预组装的真空开关管放入真空炉中; 真空开关管的内部通过间隙抽真空; 炉中的温度升高以熔化钎焊材料，从而由于固定电极棒的自重而导致扩大直径部分的下降，并且通过端板和杆的结合来密封真空开关管。或者，间隙形成为具有插入固定电极杆的扩大直径部分的通孔的支撑构件放置在端板上，并且布置至少一块板状钎焊材料在支撑构件和固定电极杆的扩大直径部分之间。

摘要： A novel method of producing a contact device for a switch is disclosed. According to the present invention, a powdered contact alloy material is pressed with a substrate on which is placed the contact material. The resulting molded article is sintered for bonding said contact alloy material to said substrate. The resulting sintered product is machined to have the shape of a contact and ultimately an electrode bar is attached by brazing to said substrate.
