Title:
ELECTRIC OPERATING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2020/108553
Kind Code:
A1
Abstract:
Disclosed is an electric operating mechanism. The electric operating mechanism comprises a slide block that is capable of directly or indirectly driving, by means of its reciprocating motion, a circuit breaker to be turned on and off. The electric operating mechanism also comprises a cam, a connecting rod, one end of which is rotatably connected to the cam and the other end is rotatably connected to the slide block, a pair of guide pressure plates that are respectively disposed on two opposite sides of the slide block and cause the slide block to slide back and forth along the guide pressure plates, and a motor that drives, by means of a gear group, the cam to rotate. The output shaft of the motor is disposed downward, the cam is located directly above the gear group, and the slide block and the gear group are arranged horizontally. Compared with the prior art, the present electric operating mechanism has the following advantages: the height of the electric operating mechanism is effectively reduced; the movement direction of the slide block is controlled by means of the guide pressure plates, facilitating reducing the overall height of the mechanism and also reducing costs; the connection structure between the components is easy to remove, and if there is damage, it can be replaced individually, without the need to scrap the whole, thereby reducing costs.
