CONTACT DEVICE, ELECTROMAGNETIC RELAY AND ELECTRICAL EQUIPMENT

WIPO Patent Application WO/2018/190210

A1

Provided are a contact device, an electromagnetic relay and electrical equipment capable of suppressing deterioration between a fixed contact and a movable contact by facilitating movement of a generated arc. The contact device (A1) is provided with a movable contactor (10), a pair of movable contacts (11) aligned in one direction, a pair of fixing terminals (12, 13), and a pair of fixed contacts (14, 15). At least one fixing terminal of the pair of fixing terminals (12, 13) has a contact holding part (12a, 13a). The contact holding part (12a, 13a) has a first fixed extension part (120a, 130a), and a second fixed extension part (120b, 130b). Regarding a current component flowing into a fixed contact in one direction or a current component flowing out from a fixed contact in one direction, the amount of current of the current component of the first fixed extension part (120a, 130a) side is greater than that of the current component of the second fixed extension part (120b, 130b) side.
