Title:
CURRENT SENSOR
Document Type and Number:
Japanese Patent JP2020118448
Kind Code:
A
Abstract:
To accurately measure current in a current sensor that measures a current based on a magnetic field generated by the current.SOLUTION: A current sensor (1) includes a conductor (10) through which a current to be measured flows and two magnetic sensors (21, 22). The conductor includes a first flow path (11), a second flow path (12) aligned with the first flow path in a width direction (X) of the first flow path, and a first connecting portion (13) which joins the first flow path and the second flow path. The two magnetic sensors are arranged side by side in a width direction, and detect magnetic fields (H1, H2) generated by the current flowing in the conductor. The conductor is provided with a first cutout portion (16), formed by cutting out a side edge on a side farther from the second flow path out of both side edges of the first flow path in the width direction. Of the two magnetic sensors, the first magnetic sensor (21) arranged closer to the first flow path than the second flow path is located in the vicinity of a side edge of the first flow path opposite to the first cutout portion.SELECTED DRAWING: Figure 1
