<p><P>PROBLEM TO BE SOLVED: To obtain a core for coils for improving insulation characteristics by achieving miniaturization and securing required creepage distance. <P>SOLUTION: In the core 2 for coils, cores 4A, 4B are covered with insulation covers 10A, 10B by combining two covers 11, 12. In the core 2 for coils, at least partial walls 12d, 12f of one cover 12 are provided in double wall structure, at least a partial wall 11d of the other cover 12 is inserted between the double wall structures of one wall, and the creepage distance between the cores housed inside and the outside are set through folded wall structure of a multiple wall composed by combining both the covers, thus enhancing insulation characteristics. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
