Example Embodiment

[0032] Embodiment 1, referring to Figures 2a and 2b, a magnetic latching relay of the present invention includes a magnetic circuit part, a contact part, and a reaction force reed. The magnetic circuit part, the contact part, and the reaction force reed are relatively fixed. The magnetic circuit part is provided with a coil 21, an E-shaped static magnetizer component 90 and a movable magnetizer component 10. The E-shaped static magnetizer component 90 is formed by connecting the U-shaped magnetizer 11 and the bar magnet 12, the coil 21 is wound on the bar magnet 12, and an insulating material is arranged between the bar magnet 12 and the coil 21 The insulating material can be injection molded with the strip magnet 12, or wrapped or coated on the strip magnet 12. The movable magnet conductor component 10 is composed of two inverted U-shaped (ie, U-shaped structure with the opening facing down) movable magnet conductor 13, U-shaped movable magnet conductor 15, magnet 14 and push car...

Example Embodiment

[0033] The second embodiment, as shown in FIG. 3, a magnetic latching relay of the present invention is different from the first embodiment in that the static magnetic conductor component 90 is composed of two U-shaped structure conductor magnets 11, and the two U-shaped structure conductors The magnets 11 are joined together.

Example Embodiment

[0034] The third embodiment, as shown in FIG. 4, a magnetic latching relay of the present invention is different from the first embodiment in that the movable magnetizer 13 and the movable magnetizer 15 of the movable magnetizer component have openings facing upwards. The U-shaped structure.

Abstract

The invention discloses a magnetic latching relay comprising a magnetic circuit part, a contact part and a counterforce reed. The magnetic circuit part is composed of a coil, an E-shaped static magnetizer component and a moveable magnetizer component; the coil is wound on the static magnetizer component and a movable magnetizer component comprises a magnetic steel and a movable magnetizer arranged at the both sides of the magnetic steel with the same structure, the E-shaped static magnetizer component is formed by connecting two magnetizers and at lease one magnetizer is provided with a U-shaped structure. The magnetic circuit takes the shape of 'two squares stacked vertically', solves the problem of unevenness of magnetic circuit contact surface and enhances the stability of product performance; the static magnetizer of the magnetic circuit part adopts the U-shaped structure, and the movable magnetizer adopts two same U-shaped or similar structures; therefore, the manufacture difficulty of parts and assemble difficulty and precision of components are reduced, the counterforce reed causes the absorbing counterforce of the relay in working state to be balanced, thus enhancing the reliability.

Description

technical field [0001] The invention relates to a relay, in particular to a magnetic latching relay. Background technique [0002] The existing magnetic latching relay consists of a magnetic circuit part, a contact part, a pushing part and a base part. Figure 1a It is a schematic structural diagram of a typical high-power magnetic latching relay. The static spring part 71 and the moving spring part 72 are installed on the base 70. The pushing part is a pushing block 73 with slots on both sides. The magnetic circuit part is composed of "workers" Shape movable magnetizer part 74, rotating shaft 75, static magnetizer 76 and coil 77 parts are formed, and " work " shape movable magnetizer part rotates around the shaft, left movable magnetizer 74a, right movable magnetizer 74b and left static The magnetic conductor 76a and the right static magnetic conductor 76b are bonded to make the magnetic circuit part work. Figure 1b It is a structural schematic diagram of the magnetic cir...
