| 摘要 | Disclosed is a magnetic latching relay having an asymmetrical solenoid structure, the magnetic latching relay comprising a magnetic circuit portion, a contacting portion, and a drive portion; the magnetic circuit portion comprises a magnetic conductive component, a coil rack, and a coil; the drive portion comprises a movable iron core; further comprising two pieces of magnetic steel, the two magnets being respectively disposed on the two sides of a coil axis and being respectively adjacent to or in contact with the corresponding sides of the magnetic conductive component; and the two pieces of magnetic steel are within the movement range of the movable iron core in the axial direction of the coil, and are biased towards the moving direction of the movable iron core when a contact is in the closed state, such that the retaining force of the moving iron core is substantially the same in both closed and open states of contact. The present invention introduces biased magnetic steel into a relay having a solenoid magnetic circuit structure to make the relay a magnetic latching relay, for ensuring low heat dissipation while solving the problem of unbalanced action reset voltage of a solenoid magnetic circuit, thus improving product performance and operational reliability. | ||||||
