Abstract:
1. A method for manufacturing a sealed contactor, the method comprising: forming a driving body by coupling a movable contact point, a shaft, and a core, and coupling a housing and a plate to form an air-tight space in which the movable contact and a movable contact point are disposed; air-tightly fixing a detachable chamber to a lower portion of the plate and forming an interior of the chamber under an insulating gas atmosphere; inserting the shaft and a core of the driving body protruded from the lower portion of the plate into a cylinder within the chamber under the insulating gas atmosphere and tightly attaching the cylinder to the plate by a tight-attachment inducing member mounted at a lower portion of the plate to form a sealing structure; exhausting the chamber; disassembling the chamber from the plate; and sealing the tightly attached plate and the cylinder.
