Patent Searching and Data


Title:
ELECTROMAGNETIC RELAY
Document Type and Number:
WIPO Patent Application WO/2020/137094
Kind Code:
A1
Abstract:
This electromagnetic relay is provided with a pair of fixed terminals, a movable contact piece, a storage part, and a magnet part. The pair of fixed terminals include fixed contacts. The movable contact piece includes movable contacts arranged so as to oppose the fixed contacts, and is movable in a direction in which the movable contacts make contact with the fixed contacts and in a direction in which the movable contacts are separated from the fixed contacts. The storage part includes a storage space for storing the fixed contacts and the movable contact piece. The magnet part includes a pair of magnets that are arranged such that different polarities oppose each other in the longitudinal direction of the movable contact piece around the storage part, the dimension of the pair of magnets in the short direction of the movable contact piece being larger than the dimension of the storage space in the short direction. The magnet part generates a magnetic field in the storage space such that arc generated between the fixed contacts and the movable contacts comes into contact with the inner wall surface of the storage part in the short direction of the movable contact piece and the arc does not come into contact with the inner wall surface of the storage part in the longitudinal direction of the movable contact piece.
