PURPOSE:To contrive secure adhesion of a transformer main body and a printed board by making adhesion of the transformer main body and the printed board using soldering heat at the time of soldering a pin terminal and a copper foil on the printed board providing a heat curing adhesive sheet at the contact point of the printed board and the transformer main body. CONSTITUTION:A heat curing adhesive sheet 23 is placed at the contact point of a printed board 21 and a projection 22, simultaneously a terminal pin 17 is inserted in a hole 24 for pin terminal insertion, soldered 25 and connected to a copper foil 26 of the printed board 21. Then, the heat curing adhesive sheet 23 fixes the printed board 21 and the projection 22 by the soldering heat. This prevents that an external force affects the pin terminal even if the external force is applied to a transformer or the printed board and there is no trouble of lead wire breaking or the foil coming off which has been a trouble for the printed board so far. |
