Title:
CURRENT DETECTOR
Document Type and Number:
Japanese Patent JP3678646
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a current detector whose productivity is superior and which can be mounted easily on a small inverter device.
SOLUTION: The current detector is provided with a current sensor 1; the current sensor 1 is composed of a core 12 which is composed of a U-shaped magnetic material to form a magnetic circuit, a magnetism detecting element 3 which detects the magnetic flux amount of the magnetic circuit and a sensor enclosure 5 which integrates the core 12 and the element 3 and which forms a U-shaped recess 13, comprising an opening at one end along the inside of the core 12; the current detector is provided with an electrical conductor 6 which supplies a current, to be detected, detected by the current sensor 1; and the current detector is constituted, in such a way that the electrical conductor 6 is situated inside the U-shaped recess 13; in the sensor element 5 inside of the mounting part of the current sensor 1.
