CURRENT DETECTION MECHANISM AND ASSEMBLING METHOD TO COMPOSE CURRENT DETECTION MECHANISM

摘要

PROBLEM TO BE SOLVED: To compose a current detection mechanism of compact and easy assemblability with the minimum number of components by utilizing the junction of a already existing tested current conductor wired in an instrument.

SOLUTION: The tested current conductor pins 10a and 10b are joined each other. The tested current conductor pin 10a is mounted on a tested current conductor pattern on a printed-wiring assembly 16, while the tested current conductor pin 10b is attached to a tested current conductor line 15. A magnetic sensor 14 is mounted on the printed-wiring assembly 16. A magnetic material core 13 includes a void part 13a and a central through hole 13b. A connector member 11 houses the tested current conductor pin 10b. A supporting member 12 supports the magnetic material core 13. A through hole 12c penetrating the test current conductor pin 10a is prepared at the central part of the supporting member 12. A projected fitting section 12a erected near the through hole 12c of the supporting member 12 is prepared.
