The bistable state magnetic latching contactor comprises a cover assembly, wherein the lower part of the cover assembly is connected with a casing; a static iron core is fixed on the upper part inside the casing; the lower part of the static iron core is connected with a movable iron core assembly; the upper part of the static iron core is connected with a movable contact assembly; a copper bush is arranged outside the static iron core; a coil assembly is arranged between the outside of the copper bush and the casing; an upper spring is arranged between the static iron core and the movable contact assembly; and a lower spring is arranged between the static iron core and the movable iron core assembly. Compared with the prior art, the bistable state magnetic latching contactor for the power supply switch of the electric tricycle aims to eliminate the electric energy consumption and improve the performance of products and eliminates the defects that the traditional electromagnetic switch loses electric energy when being connected because a coil is always in the electrified state and the coil is easy to burn down due to long-term energization and heating.
Description
Technical field
The present invention relates to a kind of electromagnetic switch, a kind of bistable state magnetic latching contactor for power supply switch of electric tricycle specifically is provided.
Background technology
Switching on and off of former traditional electrical magnetic switch is to lean against to apply certain driving voltage on the coil and realize, switch in running order (such as switch connection) then coil need apply driving voltage, only be in another operating state (disconnecting such as switch), at this moment the driving voltage on the coil just can remove, so as long as switch connection just needs coil to pass to driving voltage always, its long-time heating power consumed energy, because self-heating resistance increases, the magnetic force that produces (number of ampere turns) reduces, be reflected on the switch and can make the switch contact pressure drop, cause the switch contact unreliable; If under summer high temperature environment, because the long-term heating power of coil also may burn out coil, and disablement.
Summary of the invention
The present invention be directed to above deficiency, a kind of bistable state magnetic latching contactor for power supply switch of electric tricycle is provided, to eliminate electric energy loss and to enhance product performance as purpose, eliminate the traditional electrical magnetic switch when switch connection, because coil is in "on" position loss electric energy always, and the deficiency of long-term heating power easy burn-out coil also can be eliminated the impact that the switch contact quality is subjected to the coil power voltage fluctuation in addition.
