<p><P>PROBLEM TO BE SOLVED: To provide a surface-mounted type current sensor of magnetic noise resistance, capable of detecting multiple measurement currents with one current sensor, capable of making adjustment of output signal of the magnetic sensor unnecessary, capable of realizing improved productivity and assemblability, and also realizing size reduction and lower price. <P>SOLUTION: The current sensor is constituted, so that current paths 21, and 22 are composed of approximately parallel 2 straight parts and curved parts connecting the straight part, the magnetic body 4 is composed of a cap part and protruded part opposite to the cap part, and the straight parts of the current paths 21, and 22 are passed through the magnetic part 4. Between the protruded parts the magnetic sensors 11, 12 are disposed. Multiple gap parts are provided on the magnetic body, a pair of current path 21 and the magnetic sensor 11 , and another pair of current path 22 and the magnetic sensor 12 are arranged in respective gap parts by each set. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
