CONTACT MECHANISM AND ELECTROMAGNETIC CONTACTOR USING SAME

摘要

Provided are: a contact mechanism configured so as to be capable of suppressing electromagnetic repulsion that opens a movable contact when current is supplied, without increasing the size of the entire structure, and to improve arc-extinguishing performance; and an electromagnetic contactor using same. The shape of at least one of either a fixed contact (2), having a pair of fixed contact sections (2a, 2b) inserted in a current path, and the movable contact (3), having a pair of movable contact sections (3b, 3c) capable of being brought into contact with and separated from the pair of fixed contact sections (2a, 2b), is made a shape that generates Lorenz's force which resists electromagnetic repulsion generated in the pole opening direction between the fixed contact sections and the movable contact sections when current is supplied. Magnetic bodies (14a, 14b) that suppress force that drives an arc generated between the pair of fixed contact sections and the pair of movable contact sections towards the opposite fixed contact section side are arranged on at least either the fixed contact or the movable contact.
