DIRECT CURRENT RELAY AND MANUFACTURING METHOD THEREFOR
Abstract:
Disclosed are a direct current relay and a manufacturing method therefor. A movable contact part provided in a direct current relay comprises a movable contact and a lower yoke positioned below the movable contact configured to attenuate an electromagnetic repulsive force generated by contact between the movable contact and a fixed contact. The movable contact is provided with a coupling protrusion portion that protrudes downward. The lower yoke is provided with a movable contact coupling portion into which the coupling protrusion portion is inserted. The coupling protrusion portion can receive pressure directed radially outward after being inserted into the movable contact coupling portion. The coupling protrusion portion is expanded radially outward by the pressure. Accordingly, the outer circumferential surface of the coupling protrusion portion can be inserted into and coupled to the inner circumferential surface of the lower yoke that forms the movable contact coupling portion.
