Movable contact and stationary contact separated position, partition board are between movable contact and stationary contact, play the role of isolation, when subtracting
The rotation of speed motor energization main story, decelerating motor drives worm screw rotation, worm screw to drive turbine connection, turbine rotation that shaft is driven to connect
It connects, described to turn shaft driven gear connection, the gear band carry-over bar moves horizontally, and rack drives are moved spring and moved horizontally, and dynamic spring pushes away
Dynamic triangle contact block is moved to shell side, realizes movable contact and stationary contact point contact；When decelerating motor inverts, decelerating motor turns
Dynamic that worm screw rotation, worm screw is driven to drive turbine connection, turbine rotation drives shaft connection, described to turn shaft driven gear connection, institute
It states gear band carry-over bar to move horizontally, the movable contact and stationary contact separate, and the elasticity of spring realizes that partition board is returned to original position, inserts
Enter between stationary contact and movable contact, plays the role of arc extinguishing and isolation.
The beneficial effects of the present invention are：By moving the connection of spring and flexible arc protection component, dynamic spring movable contact to
Stationary contact moves extruding of the both ends to the triangle contact block of flexible arc protection component of spring, makes it to shell during
Side is moved, and realizes dynamic and static contact；The movable contact of dynamic spring far from stationary contact close to during, due to the effect of spring
So that partition board is resetted, between movable contact and stationary contact, plays the role of arc extinguishing and isolation；The configuration of the present invention is simple is realized automatically
Go out the electric arc that relay movable contact and stationary contact generate, and improves the service life of relay.
