Title:
CURRENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/117169
Kind Code:
A1
Abstract:
A current sensor 1 is capable of being miniaturized without lowering measurement accuracy, and comprises: a busbar 2; a magnetic sensor 6 for measuring an induced magnetic field generated from the busbar 2; a circuit substrate 7 on which the magnetic sensor 6 is mounted; a case 3 for securing the busbar 2 and the circuit substrate 7; a lid 4 for closing the case 3; and a lid magnetism-shield 8 provided to the lid 4. The lid magnetism-shield 8 has notches 8a in the periphery thereof, and in the lid 4, holes 4a are formed that expose the edges of the notches 8a in the lid magnetism-shield 8. The foregoing makes it possible to reduce the distance between adjacent lid magnetism-shields 8 when positioning the lid magnetism-shields 8 using a pressing part of a mold during the formation of the lid 4.
