<p>PROBLEM TO BE SOLVED: To eliminate the winding process of lead wires and shrink the mounting capacity by inserting an insulating member covering nearly the whole face of a coil board between the coil board and a circuit board in cooperation with a pedestal. SOLUTION: An insulating member covering nearly the whole face of a coil board 22 is inserted between the coil board 22 and a circuit board 24 in cooperation with a pedestal 21. The coil board 22 formed into a thin plate shape is laminated and fitted in the thickness direction of the pedestal 21 of an assembled current detector 20, the winding process of lead wires is omitted to simplify the assembling process, the thickness is largely reduced, and this apparatus can be made thin. When a circuit board 24 is approached to the thinned coil board 22, nearly the whole face of the coil board 22 is covered with the pedestal 21 and the insulating member 28 laminated on it, the creeping distance between the coil board 22 and the circuit board 24 is made long by multiple barrier walls 26a-26d formed on the insulating member 28, and the withstand voltage characteristic is maintained.</p> |
