Description
Technical field
A kind of magnetic latching relay is the utility model is related to, more particularly to a kind of promotion of bistable magnetic latching relay
Mechanism.
Background technology
Magnetic latching relay be it is a kind of can frequently folding, the on-load switch of the high-power electric current of defined can be carried.It is existing
A kind of relay having is to flow through current induced magnetic field using coil, then by permanent magnet, can also be protected under powering-off state
Standing state is held, enables contact closed and disconnected, to reach the electric current of control heavy load.It is widely used in electric power, distribution
And industrial automation.
But in the design of existing magnetic latching relay so that the movable contact of magnetic latching relay is contacted and produced with stationary contact
The elastic construction of raw certain pressure, generally only single spring or the movable contact spring of conduction are unilateral to be taken on.Because by unilateral
Take on structure, cause contact centering and stability poor, the eccentric contact in contact easily causes contact force unstable, thus reduces
The life-span of contact and the ability of resistance to shorting electric current, under thus causing the load-bearing capacity of powerful magnetic latching relay significantly
Drop.
In addition, in the design of existing magnetic latching relay, due to the thrust collar on the armature component of driving movable contact spring movement
Be to drive push jack to translate by rotating manner, then drive what the movable contact of movable contact spring moved by push jack, its thrust collar and push jack it
Between have micro Relative sliding and certain friction, for a long time using that can produce abrasion on rear contact surface, the generation of abrasion is led
The further increasing of frictional force is caused, so that the driving force of armature component has major part consumption rubbing in thrust collar and push jack
Wipe in power, cause magnetic latching relay Reliability of Microprocessor to decline, and reduce the service life of magnetic latching relay.
Utility model content
In order to solve the above problems, the utility model proposes a kind of pushing mechanism of bistable magnetic latching relay, it is intended to
