Abstract
The utility model relates to a drive mechanism of an electric control mechanism for a miniature circuit breaker. The drive mechanism comprises a shell, wherein a drive motor is arranged in the shell, a handle capable of rotating around a fixed shaft is arranged on the shell, a gear located in the shell is arranged at the lower end of the handle, a crank arm and a drive gear matched with the crank arm are arranged on an output shaft of the drive motor, the drive gear is meshed with the gear, and a gap is formed between the crank arm and a matching device of the drive gear. According to the scheme provided by the utility model, the provided drive mechanism of the electric control mechanism for the miniature circuit breaker is simple and reliable in structure and lower in cost.
Description
Technical field
The present invention relates to the transmission mechanism of miniature circuit breaker, focus on inventing a kind of motor-operating mechanism of brand-new miniature circuit breaker, belong to low tension switch attachment technique field with motor-operating mechanism.
Background technology
Under the prerequisite that each item index of present miniature circuit breaker improves constantly, the applicable occasion of miniature circuit breaker also more and more widely basically all can be used miniature circuit breaker at the terminal of low-voltage distribution; The occasion that has automatic control and Long-distance Control to require simultaneously is also more and more.
The automatic control system of miniature circuit breaker is little disconnected type duplicate supply automatic control system, and is many in the market, and is little disconnected type motor-operating mechanism to the execution original paper that miniature circuit breaker carries out Long-distance Control, domestic blank, abroad also seldom.
In extensive market, under the urgent situation of demand, need a little disconnected type motor-operating mechanism that is used to control miniature circuit breaker branch, combined floodgate of exploitation to come like product outside the subrogate country, fill out the cloth domestic blank.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art the transmission mechanism of a kind of miniature circuit breaker simple and reliable for structure, lower-cost with motor-operating mechanism to be provided.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of miniature circuit breaker includes housing with the transmission mechanism of motor-operating mechanism; Drive motors is installed in the housing; The handle that can rotate around fixed axis is installed on the housing, and handle, at its lower end is equipped with gear and is positioned at housing, and connecting lever and supporting with it driving gear are installed on the output shaft of said drive motors; Driving gear and gears engaged are provided with the gap between the corollary apparatus of connecting lever and driving gear.
More excellent is; Said connecting lever front end is provided with Semicircular connecting lever boss; The driving gear rear end is provided with the gear boss, and the gear boss stretches into the indentation, there of Semicircular connecting lever boss, and the arc length of the breach of the connecting lever boss of connecting lever front end is greater than the arc length of the gear boss of driving gear rear end.
More excellent is, said connecting lever is fixedly mounted on the output shaft of drive motors, and the driving gear movable set is on the output shaft of drive motors.
More excellent is that the arc length of the breach of the connecting lever boss of connecting lever front end equates with the arc length of handle rotation.
More excellent is that said connecting lever boss is identical with the thickness of gear boss.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
This product adopts horizontal mounting means, and synchronous machine is as drive source, each item technology such as manual, electronic automatic separation; Compare with external like product, this product design is ingenious, simple and reliable for structure, and product cost is very low, has very high cost performance, helps in industry, extensively promoting.
Compare (like the motor-operating mechanism of the miniature circuit breaker of Schneider) with external existing product, this product structure is simple, and low cost of manufacture, function are more perfect, has autonomous innovative technology fully.
