Description

Technical Field

[0001] The utility model relates to the technical field of magnetic latching relays, in particular to a magnetic latching relay. Background Art

[0002] The magnetic latching relay is a new type of relay developed in recent years. Since the contact state of the magnetic latching relay is maintained by the magnetic force of the permanent magnet, when controlling the contact switching, it is only necessary to input a certain width of forward or reverse DC pulses at both ends of the coil to achieve the connection and disconnection of the magnetic latching relay. Therefore, a magnetic latching relay is needed.

[0003] According to a magnetic latching relay disclosed on the patent website (authorization announcement number: CN 216412972 U), "The utility model relates to a magnetic latching relay, including a housing, a shell cover matched with the housing, a movable plate assembly installed in the housing, a first static plate, a second static plate, a magnetic steel assembly for driving the movable plate assembly, and a coil assembly for driving the magnetic steel assembly to move, the first static plate has a static contact, the movable plate assembly includes a push plate and a movable plate fixedly installed in the push plate, a movable contact is installed on the movable plate at a position corresponding to the static contact, and the second static plate is connected to the movable plate assembly by a soft copper wire. A magnetic latching relay of the utility model solves the problem of insensitivity of traditional magnetic latching relays under stress by setting the movable plate assembly as a technical solution in which the movable plate and the reed plate are installed in the push plate and are driven to move by the magnetic steel assembly, thereby providing a magnetic latching relay."

[0004] In view of the above description, the applicant believes that the following problems exist: when the device is in use, the coil assembly includes a skeleton, a coil body wrapped around the skeleton, and yokes installed at both axial ends of the skeleton, the magnetic steel assembly includes an armature that forms a magnetic attraction with the yoke, and a fixing plate for fixing the coil assembly and the magnetic steel assembly is also installed above the coil assembly in the shell, the shell has a first hinge hole, the fixing plate has a second hinge hole, the magnetic steel assembly has a hinge shaft, one end of the hinge shaft is inserted and matched with the first hinge hole, and the other end is inserted and matched with the second hinge hole to form a rotatable hinged connection, the connection state between the moving contact and the static contact is switched between contact and disconnection by rotating the moving plate assembly, the shell has a card block, and the shell cover has a buckle that matches the card block. Through the setting of the above structure, the coil assembly generates a magnetic field under the principle of coil and iron core, and moves under the magnetic force of the yoke and the armature. The magnetic steel assembly rotates under the hinge of the clamping plate, and the magnetic steel assembly pushes the pushing assembly to achieve contact and disconnection between the moving contact and the static contact. The device needs to be wound around the wiring point or welded at the wiring point during wiring, which makes the wiring steps very cumbersome. Utility Model Content
