<p><P>PROBLEM TO BE SOLVED: To make a current detector compact by minimizing the size in the conductor insertion part of a magnetic core, and thereby to downsize the magnetic core. <P>SOLUTION: An electrical junction box 1 includes the current detector 10 that has: a magnetoelectric conversion element 14; and the magnetic core 11 provided with a gap 12 in which the magnetoelectric conversion element 14 is arranged, and detects the magnetic flux induced in the magnetic core 11 as a current. The magnetic core 11 has the conductor insertion part 13 into which a conductor 20 for current detection can be inserted. The conductor 20 has: a terminal 21 connected to the other member; a circular cross-section part 22 perpendicular to the axial direction of the conductor 20 and having the diameter R set equal to or smaller than the inner diameter Y of the conductor insertion part 13; and a thin part 23 having thickness set equal to or smaller than the width dimension X of the gap 12. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
