<P>PROBLEM TO BE SOLVED: To easily attach a current detecting device to a cable providing a completed current path with a simple structure, and to eliminate variance of current detection accuracy. <P>SOLUTION: A current detecting device 1 comprises: a core module 10 having a core supporting section 11 that supports a magnetic material core 7; and an element module 20 having an element supporting section 21 that supports a hall element 8 therein. At a position of a gap portion 7B of the magnetic material core 7 in the core module 10, a cable inserting path 12 is formed. The element supporting section 21 is fitted in the cable inserting path 12. Both the end portions 7A of the magnetic material core 7 and the hall element 8 are aligned by means of a first contact surface 11A and a second contact surface 11B of the core supporting section 11, and a third contact surface 21B of the element supporting section 21. The two modules 10 and 20 are connected to each other such that the modules can relatively move, and the element supporting section 21 is fixed by means of a lock mechanism in a state in which the element supporting section 21 is fitted in the cable inserting path 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
