<p><P>PROBLEM TO BE SOLVED: To eliminate heat generation loss at a current detection part, to facilitate arrangement of a current detection mechanism around a current pattern to be measured on a printed wiring board, and to achieve reduction in size and area of footprint. <P>SOLUTION: The current detection mechanism with constituent components of a magnetic sensor 1, a holding member 2, and a magnetic core 3 is finished by only three steps of mounting the magnetic sensor 1 on the printed wiring board 4, attaching the holding member 2 to the printed wiring board 4, and attaching the magnetic core 3 to the holding member 2. The magnetic core 3 includes at least one gap part and is disposed so as to surround a cross section of a current wiring pattern 5 to be measured. The magnetic sensor 1 is mounted on the printed wiring board 4, and is further disposed in the gap part of the magnetic core 3. The holding member 2 is disposed between the printed wiring board 4 and the magnetic core 3, and holds and fixes the respective components. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
