Title:
CURRENT SENSOR
Document Type and Number:
Japanese Patent JP2016023974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current sensor that can be downsized while maintaining insulation resistance.SOLUTION: A current sensor 100 comprises: a U-shaped current path 1 through which a current to be measured flows; a U-shaped magnetic field control plate 3 for controlling a magnetic field generated by the current to be measured; a rectangular shaped insulating substrate 5; a magnetic sensor element 7a, mounted on the insulating substrate 5, for measuring the magnetic field; and a plurality of terminals 9 provided on the insulating substrate 5 and electrically connected to the magnetic sensor element 7a. The terminals 9 are arranged along a first short side 5a of the insulating substrate 5, the magnetic sensor element 7a is arranged at a center of an opening width of the magnetic field control plate 3, and both of end parts 1a of the current path 1 are arranged so as to be in contact with both of long sides 5c of the insulating substrate 5 facing each other. The current path 1 is formed so that a center of a wider part 1b formed in both of the end parts 1a of the current path 1 is closer to a second side 5b of the insulating substrate 5 than a center of a narrower part 1c formed in a vicinity of the magnetic sensor element 7a.SELECTED DRAWING: Figure 1
