Title:
CURRENT SENSOR AND MANUFACTURING METHOD OF CURRENT SENSOR
Document Type and Number:
Japanese Patent JP2015210250
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current sensor, and manufacturing method of the current sensor that can be efficiently assembled.SOLUTION: A current sensor 1 is configured to cause a current flowing to a busbar 9 to generate a magnetic field inside a feedback core 3; detect a magnetic flux in this instance by a magnetic field sensor 6; supply a current corresponding to a detection result by the magnetic filed sensor 6 to a feedback coil 4; and detect the current flowing to the busbar 9 by a current value supplied to the feedback coil 4 at a point of time when cancelling out the generated magnetic filed by the current flowing to the busbar 9. The busbar 9 is configured to be integrated with a holder 8 by insert molding along with the holder 8.
