Abstract

The invention discloses a plug-in type small circuit breaker, comprising a circuit breaker socket and a circuit breaker body. A dovetail slot adapted to be installed with the circuit breaker body is arranged on the circuit breaker socket. The circuit breaker socket is provided with an inlet terminal assembly and an installation hole connected with an external wire. The circuit breaker body comprises a housing and a conductive plug, wherein a movable contact assembly, a static contact assembly, a double-gold protection assembly, an outlet terminal assembly, an arc extinguishing system and a handle for controlling the two to be turned on or off are arranged in the housing; Wherein the conductive plug extends out of the housing, and the conductive plug is connected with the conductor of the static contact assembly; The outlet terminal assembly is provided with a conductive plate, a terminal frame and a fastening screw which are electrically connected with the exterior; As that conductiveplate of the outlet terminal assembly is connected with the terminal frame and the outlet side, the circuit breaker body can be quickly insert and extracted from the mounting groove of the circuit breaker socket for installation and replacement, and the circuit break body is convenient for users to use safely.

Description

technical field [0001] The invention relates to the field of circuit breakers, more specifically, it relates to a plug-in miniature circuit breaker. Background technique [0002] Existing miniature circuit breakers all adopt an integral structure, using a complete casing to assemble various components of the miniature circuit breaker in the casing, and the inlet and outlet terminals are also placed in the complete casing. A card plate is installed at the bottom of the miniature circuit breaker, and the miniature circuit breaker is installed on the standard guide rail through the standard guide rail installed in the meter box or distribution box. The incoming and outgoing wires are respectively connected to the external wires and pressed tightly with the screws on the terminal of the miniature circuit breaker to realize the connection and breaking operations of the power supply side and the load side to realize power supply and power failure, and to protect people, animals an...
