Automatic switching circuit breaker with novel power-obtaining structure

Abstract

The invention discloses an automatic switching circuit breaker with a novel power-obtaining structure, and the switching circuit breaker comprises a circuit breaker and a controller. Two ends of the circuit breaker are provided with conductive boards, and a side surface of the circuit breaker is closely attached to a side surface of the controller. The controller is provided with a conductive part. The switching circuit breaker is characterized in that power-obtaining springs which are used for conduction are disposed between the conductive boards and a conductive column; a side surface, closeto one side of the controller, of the circuit breaker is provided with a first through hole, and a side surface, close to one side of the circuit breaker, of the controller is provided with a secondthrough hole; the power-obtaining springs comprise a first spring part and a second spring part; the first spring part is inserted into a housing of the circuit breaker through a first through hole, and the second spring part is inserted into the housing of the controller through a second through hole, and is electrically connected with the conductive part. Through the above technical scheme, theinvention irons out the defects in the prior art, and provides the automatic switching circuit breaker with the novel power-obtaining structure. The switching circuit breaker is simple in structure, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of circuit breakers, in particular to an automatic opening and closing circuit breaker with a novel power-taking structure. Background technique [0002] With the development of smart electrical appliances, there are more and more functional requirements for circuit breakers, such as remote control of the automatic opening and closing function of the circuit breaker; automatic opening when overvoltage and undervoltage, automatic closing when normal voltage; and fee control When the ammeter is used in conjunction with the function of automatic opening of the arrears and automatic closing of the renewal fee; when the circuit breaker is connected with the controller for controlling the automatic opening and closing of the circuit breaker, it is necessary to take power from the circuit breaker, especially from the multi-pole When the circuit breaker takes power, many assembly processes, maintenance efficiency, welding pro...

AI Technical Summary

Problems solved by technology

The existing technology exists: 1. The power-taking place is designed at the inlet and outlet ends of the circuit breaker, and the conductive sheet is used to weld or directly touch the conductive plate of the circuit breaker, and the other end is electrically connected to the PCB board, and the PCB board is along the surface of the inlet and outlet ends of the circuit breaker. Pass through, and then seal the outer surface by covering it with an insulating cover plate; 2. Use the cable lead wire to be welded to the inlet and outlet terminals of the circuit breaker, and then pass through the circuit breaker and welded to the circuit board of the controller; the above structures are different in number of poles or modules. Several circuit breakers need to prepare multiple PCB boards and insulating cover plates, which brings inconvenience to production and maintenance, increases production costs, lead wires are connected to electricity, and the wiring is more complicated. The lead wires may fall off due to external force, which is unsafe.
