Description

Circuit breaker suitable for convenient installation in narrow space Technical Field The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker suitable for convenient installation in a narrow space. Background A circuit breaker refers to a switching device capable of closing, carrying and opening a current under normal circuit conditions and closing, carrying and opening a current under abnormal circuit conditions within a prescribed time. The circuit breaker is divided into a high-voltage circuit breaker and a low-voltage circuit breaker according to the application range, the division of high-voltage and low-voltage boundaries is fuzzy, the circuit breaker is generally called a high-voltage electric appliance with the voltage of more than 3kV, the circuit breaker can be used for distributing electric energy, an asynchronous motor is not frequently started, the power supply circuit, the motor and the like are protected, when serious overload, short circuit, undervoltage and other faults occur, the circuit can be automatically cut off, and the functions of the circuit breaker are equivalent to the combination of a fuse type switch, an overheat relay and the like. And the parts are not required to be changed after breaking the fault current. The power distribution is an extremely important link in the process of generating, conveying and using electricity. The distribution system comprises a transformer and various high-low voltage electrical equipment, and a low-voltage circuit breaker is an electrical appliance with wide application range. Because the application scope of circuit breaker is comparatively extensive, when installing the circuit breaker in the less regional of certain space, the installation is comparatively difficult, and traditional circuit breaker is all fixed the wire on the circuit breaker through the screw, is inconvenient for use appurtenance to carry out the fixed connection to the wire in the narrow and small space, has certain inconvenience in the time of the actual installation. Disclosure of utility model The utility model aims to provide a circuit breaker suitable for convenient installation in a narrow space, so as to solve the problems that the circuit breaker has wider application range, is difficult to install in certain areas with smaller space, is fixed on the circuit breaker by screws in the prior art, is inconvenient to use auxiliary tools to fixedly connect the wires in the narrow space, and has certain inconvenience in actual installation. In order to achieve the purpose, the circuit breaker comprises a circuit breaker body and wire inserting grooves formed in the upper end and the lower end of the circuit breaker body, wherein the side face of the circuit breaker body is provided with a mounting groove, a fixing structure is arranged in the mounting groove and comprises a connecting block which is slidably arranged in the mounting groove, a plurality of sliding grooves are formed in the connecting block at equal intervals, sliding blocks are slidably arranged in the sliding grooves, a first spring is fixedly arranged on the side wall of each sliding block and the inner wall of each sliding groove, and the sliding blocks are movably connected in the wire inserting grooves.
