Piezoelectric transformer |
摘要 |
A piezoelectric transformer element 1 is supported by a plurality of contact pins 5b provided on a printed wiring board 6. The contact pins are directly contacted to lower electrodes of the piezoelectric transformer element at its nodal points. An insulating case 4 accommodating the piezoelectric transformer element 1 is provided with a plurality of leads 3 which contact upper electrodes of the piezoelectric transformer element 1 at its nodal points. The insulating case 4 and the printed wiring board are combined together to provide electrical connection between the leads and wirings of the printed wiring board.
