Molectron, quiet spring molectron and motor, described pedestal and cover plate cooperate, and movable spring group component and motor are installed in pedestal
On, quiet spring molectron corresponding with movable spring group component be connected it is characterised in that：Also include conversion gear, sector gear, fixing axle,
Worm screw and binding post, described conversion gear is arranged on pedestal, and worm screw is arranged at motor, conversion gear include worm gear with
Gear, fixing axle is coaxial, the worm and wheel engagement of worm gear and gear, and gear is engaged with sector gear, and binding post plugs
On pedestal；Reasonable in design, when motor rotates, drives worm screw to rotate, the snail of the conversion gear that worm screw drive is engaged with
Wheel rotates, because gear is coaxial with worm gear, therefore gear thus rotates and drives the sector gear being engaged with to rotate, and motor turns
Dynamic, realize movable spring group component action so that the closure of stationary contact contact of the movable contact of movable spring group component and quiet spring molectron and
Disconnect.
Preferably, the position phase of the stationary contact of quiet spring molectron described in the utility model and the movable contact of movable spring group component
Corresponding；Realize the closed and disconnected of movable contact and stationary contact contact.
Preferably, being provided with motor output shaft on motor described in the utility model, one end of worm screw is connected to this motor
On output shaft；When motor is rotated, worm screw is driven to rotate.
Preferably, motor described in the utility model adopts micro-step motor；So that controlling more accurately, by specific biography
Motor torque is changed into linear motion by motivation structure, by changing direction of motor rotation, can achieve closure and separating action, realizes
Relay function.
This utility model compared with prior art, has advantages below and effect：Reasonable in design, low cost, performance
Stable, easy for installation, long service life, contact is reliable, meets the use demand of people.
