Abstract

The invention provides a circuit breaker with a protection device. The circuit breaker comprises a circuit breaker body, terminals fixedly connected to the outer wall of the circuit breaker body and protection shells, wherein an upper slide chute and a lower slide chute are formed in the upper side and the lower side of each terminal respectively; each protection shell is located at the outer side of the corresponding terminal; and an upper plane and a lower plane of each protection shell are in embedded connection with the corresponding upper slide chute and lower slide chute respectively. The circuit breaker with the protection device has the beneficial effects that the exposed terminals can be effectively covered through the arranged protection shells, so that people are prevented from accidentally touching the terminals during operation; an electric shock is effectively avoided; and the safety is ensured. Meanwhile, the protection shells correspond to the terminals one by one, so that the circuit breaker is convenient to use.

Description

Technical field [0001] The invention belongs to the field of circuit breakers, and in particular relates to a circuit breaker with a protection device. Background technique [0002] The circuit breaker is used to cut off or connect the circuit. Compared with the switch, the circuit breaker is equipped with an anti-short circuit and current limiting device, which has higher safety. Therefore, it is widely used in building circuits and various electrical equipment. The existing circuit breakers have the following shortcomings: most of the circuit breakers are combined and used in the electrical box, and the number of exposed terminals increases accordingly. When people operate one or several circuit breakers, they accidentally touch one or more of the exposed terminals. The probability of electric shock caused by the terminal increases accordingly. Summary of the invention [0003] In view of this, the present invention aims to provide a circuit breaker with a protection device to ...
