PROBLEM TO BE SOLVED: To protect both primary and secondary coils and a power switch of an iron core-coil assembly from deterioration in insulation. SOLUTION: An iron core-coil assembly 10 crosses a non-end outer annular iron core 13 and the interior enclosed with an outer annular iron core 14 and supports by penetrating primary and secondary both coils 11, 12, and is housed in a main housing part 21 of an insulation case 20, and a power switch 17 is housed is an auxiliary housing part 23 of the insulation case 20. When burying and fixing by a solidifying layer 28, made of an insulation resin implanted into the respective housing parts 21, 23, a protective plate 31 of an insulation cover 30 provided integrally with the protective plate 31 coating the primary and secondary both coils 11, 12 in the main housing part 21, and a lid 32 clogging an upper plane of the auxiliary housing part 23 is supported horizontally inside the main housing part 21. Furthermore, the protection plate 31 is fixed on the primary and secondary both coils 11, 12 by a solidifying layer 38 made of an insulation resin implanted into the main housing part 21, and also the lid 32 of the insulation cover is fixed on the auxiliary housing part by the solidifying layer 38 which is made of the insulation resin in the auxiliary housing part 23. |
