US Patent 11293990 Sensor unit

A sensor unit includes a plurality of bus bars connected to a plurality of switch modules, a terminal block that integrally links the bus bars, and a plurality of magnetoelectric conversion parts that detect currents flowing through the bus bars. Embedded parts of the bus bars embedded in the terminal block are aligned in a first predefined direction with spaces therebetween. The magnetoelectric conversion parts are provided in the terminal block such that they face the embedded parts. Extension parts, extending in the first predefined direction, of any two embedded parts adjacent to each other in a predefined direction adjoin each other in a second predefined direction that intersects the first predefined direction.
