Title:
CURRENT DETECTOR
Document Type and Number:
Japanese Patent JP2018165716
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology for preventing a change in output characteristics accompanied by a short-term temperature change or a long-term secular change.SOLUTION: A current detector comprises: a magnetic core 110 arranging a hall element to be used for detecting currents to be detected in a gap; a resin case 102 the inside of which is filled by a filling material 106 in a state where the magnetic core 110 is stored together with the hall element; and adhesive 140 arranged so as to be interposed between the resin case 102 and the magnetic core 110 for regulating deformation of the magnetic core 110 accompanied with a dimensional change in the gap caused by a volumetric change in the filling material 106 in the resin case 102.SELECTED DRAWING: Figure 5
