Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：As shown in the figure, a kind of small-sized open circuit with new type handle
Device automatic reclosing brake mechanism including housing 2, is equipped with power source 31, rotating disc and oscillating rod 35 in the housing；The power
Source drives rotating disc 33 to rotate by transmission mechanism 32；Further include the drive plate 34 being coaxially disposed with the rotating disc, described turn
Moving plate axial direction outer wall eccentric part is equipped with pushing block 331, is correspondingly provided with arc groove 341, institute with the pushing block on the drive plate
It states drive plate and the drive plate is driven to rotate by stretching into the pushing block of the arc groove;The oscillating rod is rotatably mounted on
Housing exterior walls, the rotating disc are equipped with the touch part 342 for driving the oscillating rod rotation, and the oscillating rod is used to turn
By the way that dropout needle movement is driven to make small size breaker when dynamic.One of optionally, the lock in breaker is equipped with
Dropout needle, oscillating rod stir dropout needle lock are made to thread off when swing, when use, such as want miniature circuit breaker combined floodgate, then
It needs to give control signal wire one voltage input signal, after voltage input signal provides, motor starts towards positive direction（Clockwise）
Rotation（The rotation direction of motor is completely by smart circuit electronic component module plate（Pcb board）Control）.Since worm screw is fixed on
On motor transmission shaft, so worm screw also rotates together.At this moment the worm gear being engaged with gear on worm rotates clockwise, band nutating disk
It rotates counterclockwise, finally circuit breaker handle is driven to carry out closing operation with mandrel action gear.When drive plate is according to intelligent electricity
The time programming of the wiring board setting on road reaches designated time progress closing operation, and motor stalls reach after receiving instruction
Precalculated position.Corresponding each gear also stops operating, and be parked on closing position, and shunt trip is also by drive plate drive
At the combined floodgate of lower section.At this moment miniature circuit breaker belongs to "on" position.Miniature circuit breaker, can be by manually pulling under "on" position
Fixed handle can arbitrarily separating brake or combined floodgate.Further, the product in miniature circuit breaker assembling process, using conductive column and
Conductive column using the elasticity of power spring, is pressed on smart circuit electronic component module plate by 29 combination of power spring
On, and make conductive column and smart circuit electronic component module plate electrical connection contact good；On the contrary, the other end also utilizes spring
Elasticity is pressed on conductive column on the arc striking piece of miniature circuit breaker and does not need to soldering iron welding, is easily electrically connected.Assembling and
Disassembly process is quick and easy.
