Problems solved by technology
[0003] In the existing circuit breakers, because the size of the indicating mechanism and the guide rod is usually relatively small, it is not only difficult to install during assembly, but also often occurs due to assembly errors resulting in functional failure, and the fault tolerance rate is small, not only difficult to assemble, but also time-consuming and laborious to assemble. It is inconvenient to install the circuit breaker, and it needs regular maintenance, and the disassembly is cumbersome, which is not convenient for the operator to operate and repair. These problems need to be solved urgently

The invention relates to a novel circuit breaker device convenient to install. The novel circuit breaker device comprises a base, a circuit breaker body, an insulation shell, threading holes, bunchingrings, an insulation sleeve and a wiring piece, wherein the circuit breaker body is fixedly arranged on the base, the insulation shell is fixedly arranged at an outer side of the circuit breaker body, the two threading holes are formed in the circuit breaker body, the bunching rings are movably arranged in the threading holes, and contacts are fixedly arranged below the threading holes. In the novel circuit breaker, a wire can be classified and connected by the contacts and the wiring piece, and the novel circuit breaker is difficult to get wrong; by the arranged sliding rail, a sliding blockand a metal sheet, unwinding operation can be achieved, the novel circuit breaker is simple to install, and circuit installation and maintenance is more convenient; a suction disc is arranged below the base, the novel circuit breaker is conveniently placed at an installation position; by the threading holes and the bunching rings, installation and management of a wire are facilitated; an operatoris safe to use by the arranged insulation shell; and moreover, the shell is detachable, and the novel circuit breaker device is convenient to install.
Description
technical field [0001] The invention relates to the technical field of low-voltage electrical equipment, in particular to a novel circuit breaker device which is easy to install. Background technique [0002] Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheating and underheating relays, etc., and there is generally no need to change parts after breaking the fault current. [0003] In the existing circuit breakers, because the size of the indicating mechanism and the guide rod is usually relatively small, it is not only difficult to install during assembly, but also often occurs due to assembly errors resulting in functional failure, and the fault tolerance rate is small, not only difficult to assemble, but also tim...
