VACUUM INTERRUPTER FOR CONTACTOR AND METHOD OF MANUFACTURE THE SAME

摘要

PURPOSE: A vacuum interrupter for a switch and a manufacturing method thereof are provided to reduce the number of manufacturing processes by spot-welding the assembly to a flange after a guide bearing and a bearing cap are assembled. CONSTITUTION: A body(110) is made of insulation materials and has a cylindrical shape. A fixed electrode(180) is installed on the lower side of a body. A fixed contact(190) is installed on the upper side of the fixed electrode. A movable electrode(120) operates a bellows(121). A flange(150) is installed on the upper side of the body. A bearing cap(140) is attached to the flange. A guide bearing(130) is made of the insulation materials and is formed on the bearing cap.
