Abstract
Provided is a multi-breakpoint built-in connection direct-current circuit breaker. The invention mainly aims to solve the problem that because series wiring of the existing multi-breakpoint built-in connection direct-current circuit breaker is often carried out at an external wiring terminal of the circuit breaker to make two or more poles of the circuit breaker connected in series into a series connection breakpoint, users cannot use the circuit breaker conveniently, and the occupied space is large. The multi-breakpoint built-in connection direct-current circuit breaker is characterized in that the bottom of each fastening screw passes through a base and each fastening screw is equipped with a matching fastener; the bottom of the base is provided with a mounting cavity; a series connection plate is arranged between the top inner wall of the mounting cavity and the fasteners; and the two ends of the series connection plate are respectively connected with the adjacent fastening screws. The invention provides a multi-breakpoint built-in connection direct-current circuit breaker which adopts an internal connection mode. The series connection plate is adopted for connection at the bottom of a wiring terminal of the circuit breaker to make two or more poles of the circuit breaker connected in series into a series connection breakpoint, and the shape of a conductor for connection does not move out of the shell of the circuit breaker. The multi-breakpoint built-in connection direct-current circuit breaker has the advantages of compact structure, convenient use and less space occupation.
