Abstract

The invention relates to a magnetic latching relay with a self-locking structure, which comprises a shell, an electromagnetic deflection mechanism and a contacting device, wherein the electromagnetic deflection mechanism comprises an electromagnetic coil, a magnet and a yoke, wherein the center of the magnet is provided with a fixed rotating shaft, and the contact device comprises a movable contact and a static contact; the magnet is provided with a swinging arm which is connected with a hinge mechanism through a connecting rod, the hinge mechanism comprises a fixed arm and a movable arm, the fixed arm is connected with a fixed seat, the movable arm is connected with the movable contact through a push sheet, and the magnet pushes the movable contact to be in contact with the static contact when acting and ensures that the hinge mechanism is in a self-locking state. The hinge mechanism is additionally arranged between the swinging arm of the magnet and the movable contact of the contact device, and is self-locked when the movable contact is pushed to be in full contact with the static contact; meanwhile, the bounce of the movable contact can ensure that the self-locking state of the hinge mechanism is more stable. The invention has the advantages of simple structure, convenient manufacture and installation, higher reliability and capability of stably keeping better contact conduction state.

Description

technical field [0001] The invention relates to a relay, in particular to a magnetic latching relay which can stably maintain a contact conduction state and has a self-locking structure. Background technique [0002] Chinese patent CN 2374968Y, on April 19, 2000, disclosed an invention patent application titled "Magnetic Latching Relay". Its technical solution mainly includes a magnetic circuit system and a contact system. The chassis of the base is provided with embedded slots for the magnetic circuit system and the contact system and sockets for the bracket. There are small shaft support holes in the middle of the bracket, pins at both ends of the bracket, and yoke sleeve holes between the small shaft support holes and the pins. The patent application is mainly to solve the problems of difficult product assembly and unstable product performance. [0003] At present, during the use of the existing magnetic latching relay and the above-mentioned magnetic latching relay, due...
