Title:
CURRENT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/095566
Kind Code:
A1
Abstract:
A current detection device according to the present invention can suppress the deformation of a case or cover due to increased temperature, can accurately detect a magnetic field generated by currents which are to be measured and respectively flow through a plurality of bus bars, and can maintain high current detection accuracy, wherein first shielding plates are arranged on a magnetic sensor side and second shielding plates are arranged on a bus bar side such that the bus bars and a magnetic sensor are sandwiched therebetween in the thickness direction of the bus bars, the plurality of first shielding plates on the magnetic sensor side are integrally formed with the cover, at least a portion of the cover is divided between adjacent first shielding plates, and the plurality of second shielding plates arranged on the bus bar side are integrally formed with the case.
