Abstract

The utility model relates to the technical field of electrical equipment, and discloses a mechanical electrical equipment circuit breaker convenient for wiring, which comprises a front shell and a rear shell, and the front shell is fixedly arranged at the front end of the rear shell. When the mechanical and electrical equipment circuit breaker convenient for wiring is in wiring operation, wiring terminals are installed and fixed at the end positions of an upper connecting wire harness and a lower connecting wire harness respectively, and then the terminals are correspondingly inserted into connector lugs in inner grooves respectively; a first inserting hole and a second inserting hole in the pressing plate are inserted into the inner groove corresponding to the exteriors of the threaded column and the second inserting hole respectively, and finally two sets of rubber gaskets are arranged on the outer side of the threaded column in a sleeving mode and are screwed into the exterior of the threaded column through connecting nuts; according to the utility model, the pressing plate can be used to press and fix the wiring terminals on the three groups of connector lugs in the inner groove, multiple groups of wires can be fixed at the same time, the wiring process is simplified, quick wiring can be carried out on the open circuit, and the problem that simplified wiring of the circuit breaker is inconvenient is solved.
