COIL UNIT
Document Type and Number:
Japanese Patent JP2018046142
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a coil using the wiring pattern of a substrate in the winding, with a low loss structure not causing a gap in a core.SOLUTION: A primary winding 11 wound spirally around an annular core 5 is constituted of wiring patterns 36a-36f for joining the terminals 73a-73e, 75a-75e of an FPC7, respectively, to corresponding connection terminals 32b-32f, 33a-33e of a substrate 3, and conductive patterns 71a-71e for interconnecting them in series. A secondary wiring 13 wound spirally around the annular core 5 is constituted of wiring patterns 37a-37c for joining the terminals 93a, 93b, 95a, 95b of an FPC9, respectively, to corresponding connection terminals 34b, 34c, 35a, 35b of the substrate 3, and interconnecting them, and conductive patterns 91a, 91b for interconnecting them in series.SELECTED DRAWING: Figure 1
