摘要： A gas bushing is constructed in such a manner that a center conductor includes: a main electrically-conductive portion having a first outside diameter; and a larger-diameter portion being provided in an upper end portion of the center conductor and having a second outside diameter that is larger than the first outside diameter; and a connection portion connecting the main electrically-conductive portion and the larger-diameter portion together; a lower end of the larger-diameter portion is positioned lower than a lower end of the flange portion, and the lower end of the larger-diameter portion and an upper end of the connection portion are connected together in such a manner that a curvature of an external surface of the center conductor is continuous and that a connecting section has a round shape.

摘要： A piston rod includes a large-diameter portion that is formed on the side of a movable contact, and a small-diameter portion that is formed on the side of an insulating operation rod relative to the large-diameter portion, and that is formed with an outer diameter smaller than the inner diameter of an inner peripheral surface of an insulating cylindrical member. The insulating cylindrical member includes a cylindrical portion that is interposed between the outer peripheral surface of the small-diameter portion and the inner peripheral surface of the insulating operation rod, a bottom portion that is arranged opposed to the distal end of the small-diameter portion, and a through hole through which a coupling pin is inserted through the piston rod and the insulating operation rod.
摘要翻译：活塞杆包括形成在可动触头侧的大直径部分和形成在绝缘操作杆相对于大直径部分侧的小直径部分，并且形成有外径小于绝缘筒状构件的内周面的内径。所述绝缘筒状部件具有设置在所述小径部的外周面与所述绝缘操作杆的内周面之间的圆筒部，与所述小直径部的前端相对配置的底部，以及连接销穿过活塞杆和绝缘操作杆插入的通孔。
