Title:
CURRENT DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2015083944
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current detection device capable of highly accurately and reliably measuring high current.SOLUTION: A current detection device comprises a first wiring member 11 composed of a highly conductive material, a second wiring member 12 composed of a highly conductive material, and a resistive element 13 composed of a metal material having a smaller resistance temperature coefficient than the highly conductive materials used as these wiring members. The first wiring member and the second wiring member are welded to the resistive element. The second wiring member is longer than the first wiring member. The second wiring member 12 includes a plurality of bent parts 16, 17, and 18. The plurality of bent parts include bent parts in a horizontal direction and in a vertical direction. Voltage detection terminals 14 and 15 are formed near the resistive element 13 in the first wiring member 11 and the second wiring member 12.
