Magnetic latching circuit structure and relay

Abstract

A magnetic holding circuit structure and a relay are disclosed. The magnetic circuit structure includes a yoke, a magnetic assembly, and a coil assembly. The magnetic assembly, disposed within the magnetic circuit space of the yoke, includes two permanent magnets and a movable magnetic conductor movably disposed between the permanent magnets. The two permanent magnets are fixedly disposed relative to the yoke, with two first magnetic pole faces of the permanent magnets contacting the inner ring surface of the yoke, and two second magnetic pole faces facing each other with the same polarity. The movable magnetic conductor has movable pole faces at both ends, with each movable pole face facing the two second magnetic pole faces. When the magnetic holding circuit structure is in a holding state, one movable pole face is in contact with only one of the second magnetic pole faces, while the other movable pole face is separated from the other second magnetic pole face. The coil assembly is fixedly disposed relative to the yoke and configured to drive the movable magnetic conductor to move between the permanent magnets in response to an input signal. none
