Abstract
A magnetic latching relay comprises a magnetic circuit system, a contact system and an auxiliary force spring. The magnetic circuit system, the contact system and the auxiliary force spring are relatively fixed. The contact system comprises a static spring part and a moveable spring part. The magnetic circuit system comprises an E-shaped stationary magnetizer component and a movable magnetizer component. A coil is wound on the stationary magnetizer component, and an insulating material layer is arranged between the stationary magnetizer component and the coil. The movable magnetizer component is arranged above the stationary magnetizer component and is linked with the moveable spring part through a pushing clamp. The movable magnetizer component comprises a steel magnet and two identically-structured movable magnetizers connected to the two sides of the steel magnet. The two movable magnetizers of the movable magnetizer component move and shift between different pole faces contacting the stationary magnetizer component along with movement of the movable magnetizer component. The auxiliary force spring is mounted in a position for preventing a contact from bouncing to provide auxiliary counter-force in the closing process of the contact.

[summary of the invention]
The technical problem that the present invention solves be overcome prior art deposit protect problem, provide a kind of simple in structure, work simplification, and magnetic latching relay stable and reliable for performance.
The present invention is achieved by the following technical solutions: a kind of magnetic latching relay, comprise magnetic circuit system, contact system, auxiliary power spring, wherein, described magnetic circuit system, contact system, auxiliary power spring are relatively fixing, described contact system comprises quiet spring part and moving spring part, described magnetic circuit system comprises the static magnetic conductor parts of an E shape and movable magnetic conductor parts, and coil winding, on static magnetic conductor parts, is provided with insulation material layer between static magnetic conductor parts and coil; Movable magnetic conductor parts are arranged on the top of static magnetic conductor parts and are partly connected by a push card and moving spring; Movable magnetic conductor parts comprise a magnet steel and are connected to two movable magnetic conductors with same structure of magnet steel both sides, movably two movable magnetic conductors of magnetic conductor parts mobile transposition in the different pole-faces that contact from static magnetic conductor parts with the movement of movable magnetic conductor parts; Auxiliary power spring fitting provides the position of auxiliary counter-force for preventing that contact generation from bouncing in closing of contact process.
Further, described static magnetic conductor parts consist of two U-shaped structure magnetic conductors, and two U-shaped structure magnetic conductors also together.
Further, the E shape structure that described static magnetic conductor parts are formed in one.
Further, described auxiliary power spring is fixed on the static magnetic conductor parts of E shape.
Further, described auxiliary power spring is fixed in push card.
Compared with prior art, the magnetic circuit system of magnetic latching relay of the present invention directly drives its movable magnetic conductor assembly linear movement, and this has reduced the difficulty of part manufacture and difficulty and the precision of parts assembling, has simplified production technology, has reduced production cost.In addition, due to auxiliary power spring being installed in magnetic latching relay, and auxiliary power spring fitting provides the position of auxiliary counter-force for preventing that contact generation from bouncing in closing of contact process, while making magnetic latching relay work, on movable contact spring, moving contact can steadily contact with fixed contact on static contact spring piece, both prevented the contact damage that clashes between contact and cause when contacting fast, also prevented that the contact on moving spring from the problem that spring causes arcing occurring, and has improved the reliability of magnetic latching relay.
