Description

Mutual inductor connecting assembly for intelligent circuit breaker Technical Field The application relates to the technical field of electrical equipment, in particular to a transformer connecting assembly for an intelligent circuit breaker. Background Currently, in the design of intelligent circuit breakers, the circuit boards of each layer are usually connected through wires, and the wires not only carry the task of power transmission, but also are responsible for transmitting various control signals. However, when the circuit boards in the above circuit breaker are electrically connected through wires, a worker is required to manually weld the wires, which increases the production cost and reduces the production efficiency, and thus needs to be improved. Disclosure of utility model In order to simplify the assembly process of the circuit breaker and improve the production efficiency, the application provides a transformer connecting assembly for an intelligent circuit breaker. The application provides a mutual inductor connecting component for an intelligent circuit breaker, which adopts the following technical scheme: The utility model provides a mutual-inductor coupling assembling for intelligent circuit breaker, includes first circuit board, second circuit board, is located the mutual-inductor seat between first circuit board and the second circuit board, a plurality of holes of stepping down have been seted up on the mutual-inductor seat, fixedly connected with row needle in the hole of stepping down, the both ends of row needle wear out from the mutual-inductor seat respectively, be provided with respectively on first circuit board and the second circuit board with row needle grafting complex female seat, set up a plurality of jacks that are used for supplying row needle to stretch into on the female seat, be equipped with electrically conductive piece in the jack, row needle is connected first circuit board and second circuit board electricity through electrically conductive piece. Through adopting above-mentioned technical scheme, when needs connect first circuit board and second circuit board, only need place first circuit board in place earlier, put the mutual-inductor seat on first circuit board again, make the row needle stretch into the female seat of first circuit board, then put the second circuit board on the mutual-inductor, and make the row needle stretch into in the female seat of second circuit board, can realize the electricity of first circuit board and second circuit board and be connected, and need not the manual welding wire of staff and connect first circuit board and second circuit board, and then simplified the assembly process of circuit breaker, improved production efficiency.
