Current detection system for use in e.g. electric vehicle, has metallic washer brought into contact with shunt, so that current passes through another metallic washer and through metalized holes towards central axis

摘要

The system (20) has a metal rod (18) connected by a metallic washer (34) to a surface of a plate (12) of a printed circuit board, where the plate is provided with a number of metalized holes (38) spaced from a central axis (35). A shunt (47) is brought into contact with another surface of the plate of the printed circuit board. Another metallic washer (48) is brought into contact with the shunt, so that a current passes through the former metallic washer and through the holes towards the central axis. A metal ring (32) is placed between the metal rod and the former washer.
