PURPOSE:To obtain the noise absorbing device fitted to an optional part on a board by providing two split magnetic bodies combined while being penetrated to two board openings and inserting a wiring section between them from upper and lower sides. CONSTITUTION:Board openings 4a, 4b are respectively formed to both sides of a wiring part 3 and two split magnetic bodies 5a, 5b are combined as shown in the arrow B through the board openings 4a, 4b. As a result, the wiring part 3 is clipped by the split type magnetic bodies 5a, 5b from the upper and lower parts. Furthermore, both ends of the split magnetic bodies 5a, 5b act like legs 6 and they are formed to be nested. The board openings 4a, 4b are formed to the board 1 and the split magnetic bodies 5a, 5b are fitted to allow the split type magnetic bodies 5a, 5b forming a closed magnetic path to absorb high frequency spurious radiation noise emitted from the wiring section of a signal line or the like. |
