Abstract
A current sensor, relating to the field of current sensors, is used to reduce the cost and assembly difficulty of current sensors. The current sensor includes a support hopper, a ring-shaped iron core, a sensing PCB board, a chip, an adapter PCB board, an adapter terminal, and an external terminal. The ring-shaped iron core has a notch located at a mounting cavity. The sensing PCB board is disposed within the mounting cavity and located at the notch, and a connection port is formed on the sensing PCB board. The chip is disposed on the sensing PCB board, with at least a portion of the chip located within the notch. The adapter PCB board is disposed outside the ring-shaped iron core and within the mounting cavity, with an adapter port and an external port respectively provided on opposite sides of the adapter PCB board. The adapter terminal is disposed between the adapter PCB board and the sensing PCB board, with both ends of the adapter terminal fixedly disposed on the connection port and the adapter port respectively. The external terminal extends beyond the support hopper, with one end of the external terminal located within the mounting cavity disposed on the external port.
