<P>PROBLEM TO BE SOLVED: To provide a coreless type current detection device in which variation of a gap between a magnetoelectric transducer and a bus bar due to a dimensional tolerance and thermal expansion is prevented, and consequently variation of current detection sensitivity is prevented. <P>SOLUTION: The current detection device 10 includes an electronic board 2 on which a hall element 1 is mounted, a metal spacer 5, and a current detection bus bar 6. The electronic board 2, spacer 5, and current detection bus bar 6 are connected with a connection mechanism comprising a plurality of screws 4 passing through a plurality of first through holes 21 at both sides of the hall element 1 on the electronic board 2, through holes of the tubular spacer 5, and a plurality of third through holes 62 of the current detection bus bar 6; and a plurality of screw receiving sections 63 to which the screws 4 are screwed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
