Abstract

The invention discloses a magnetic latching relay of a directly-operated type magnetic circuit structure. The magnetic latching relay comprises a magnetic circuit part, a contacting part and a pushing part. The magnetic circuit part comprises a coil, an iron core, an inner yoke, an outer yoke, two permanent magnets and two pole pieces. The inner yoke and the outer yoke are of an opening-shaped structure respectively. The iron core is arranged in the coil. The coil is arranged in the inner yoke in a sleeved mode. The outer yoke is arranged outside the inner yoke in a sleeved mode. The two pole pieces are arranged between the inner yoke and the outer yoke respectively. Movable gaps are arranged between the pole pieces, the inner yoke and the outer yoke. The two ends of the iron core penetrate out of the inner yoke respectively and are fixed with the corresponding pole pieces. The two permanent magnets are symmetrically arranged between the inner yoke and the outer yoke with the iron core as an axis respectively. The two faces of each permanent magnet are attached with the inner yoke and the outer yoke respectively. According to the magnetic latching relay, large driving power can be formed during relay coil electrifying, large retention force can be formed during relay coil outage, the magnetic latching relay has the advantages that magnetic disturbance resisting capacity is enhanced, product size is reduced, and cost is lowered.

Description

technical field [0001] The invention relates to a magnetic latching relay, in particular to a magnetic latching relay with a direct-acting magnetic circuit structure. Background technique [0002] The structure of the existing magnetic latching relay consists of a magnetic circuit system, a contact system, a driving part and a base. The magnetic circuit system generally consists of two basically symmetrical magnetic circuits, including stationary magnetizer parts, movable magnetizer parts and coils. The contact system includes a moving spring part and a static spring part. The pushing part is generally played by a push card. The relay coil passes the positive pulse voltage, the magnetic circuit system works, pushes the card to push the moving spring part, and makes the contacts contact, the relay operates, the coil passes the reverse pulse voltage, the magnetic circuit system works, pushes the card to push the moving spring part, and the contacts disconnected, the relay res...
