The invention relates to a cam switch-on / off mechanism for a switching device. The cam switch-on / off mechanism comprises a cam handle (2) for switching on / off the switching device, a push rod (3), a thruster (4) and a base shell (1), wherein the cam handle (2) comprises a handle (S4), a cam (S5) and a revolving shaft (S0); the cam (S5) is sleeved on the revolving shaft (S0); the handle (S4) is fixedly connected to the upper portion of the cam (S5); one end of the push rod (3) is connected with the output end of the thruster (4), and the other end of the push rod (3) is connected with the cam (S5) in a matching way; the handle (S4) is connected with the handle or the handle revolving shaft of the switching device; the thruster (4) is used for driving the push rod (3) to move linearly in a reciprocating way; the push rod (3) is used for driving the cam handle (2) and the handle of the switching device rotate clockwise or anti-clockwise in order to realize switch-on / off of the switching device. The cam switch-on / off mechanism is simple in structure, and can be switched on / off by using one set of mechanism, the size of a product is reduced, and the production and assembly costs are lowered. Moreover, the mechanism acts stably and reliably, and is high in security.
Description
[technical field] [0001] The invention relates to the technical field of electrical switchgear, in particular to a cam closing and opening mechanism for switching electrical appliances. [Background technique] [0002] The non-manual closing and opening actions of switching appliances are usually completed by rotating motors, linear motors, electromagnets (electromagnetic coils) or other forms of power devices. The utility model patent with the authorized announcement number CN203165828U and the patent number 201320135199.X discloses an actuator for operating a circuit breaker. This patent uses two sets of mechanisms to realize the closing and breaking of MCB (miniature circuit breaker). Among them, the rotating motor drives the closing mechanism (rack, handle and handle connector) to complete the closing of the MCB; the tripping connector (electromagnet not shown) completes the opening of the MCB; and the closing mechanism of the linear motor includes It consists of a linea...
