<p>PROBLEM TO BE SOLVED: To improve sensing accuracy of a temperature sensing sensor of a high-voltage transformer and simplify the mounting work of the sensor, by providing in its insulation molding portion a receiving portion of the temperature sensing sensor for sensing the temperature of its secondary coil. SOLUTION: A secondary coil portion 40 has not only an I-shaped core 21 and E-shaped core 23, but also has an insulation molding portion 45 for insulating the portion 40 from other parts. In this insulation molding portion 45, a sensor receiving portion 47 for the reception and fastening of a temperature sensing sensor 43 is provided. The temperature sensing sensor 43, received in the sensor receiving portion 47, is provided on the side of a secondary coil 41 and is molded together with the secondary coil 41, and is fastened to the insulation molding portion 45, when molding the portion 45. Also, in the secondary coil portion 40, a pair of coupling terminals coupled to other parts in an appliance part chamber is provided in a position separated from the temperature sensing sensor 43, i.e., in a position opposite to the sensor receiving portion 47. Thereby, the sensing accuracy of the temperature sensing sensor 43 is enhanced, and its mounting work is simplified.</p> |
