权利要求

1. A piezoelectric transformer comprising a rectangular plate shaped ceramic body with one-half of its length polarized in the direction of thickness and the remaining half polarized in the axial direction, a pair of input electrodes applied on the opposite surfaces of said one-half polarized in the direction of thickness, and an output electrode on the outer end of said remaining half polarized in the axial direction, the improvement which comprises an output electrode of conductive rubber, said output electrode being fitted over the outer end of said longitudinally polarized half of said ceramic body and having an integral stem extension adapted for connection to a lead wire remote from said output electrode.

2. A piezoelectric transformer comprising a rectangular plate shaped ceramic body with one half of its length polarized in the direction of thickness and the remaining half polarized in the longitudinal direction, a pair of input electrode plates of conductive rubber, said electrode plates covering and in direct electric contact with substantially the entire surface of said half polarized in the direction of thickness, means to fixedly secure said electrode plates tO said ceramic body and adapted to support said ceramic body, and an output electrode of conductive rubber fitted over the outer end of said remaining half polarized in the longitudinal direction.

3. The piezoelectric transformer according to claim 2 wherein said input electrode plates include integral means to connect said input lead wires to said electrode plates.

4. The piezoelectric transformer according to claim 3 wherein said integral means comprise axial extensions of said electrode plates.

5. The piezoelectric transformer according to claim 3 wherein said integral means comprise projections vertically extending from the surface of said electrode plates.

6. The piezoelectric transformer according to claim 2 wherein said clamping means comprises a pair of stationary stays spaced apart from said ceramic bodies and a pair of supporting rods arranged between respective stays and said electrode plates, said supporting rods being made of elastic conductive rubber and wherein said input leads wires are connected to said supporting rods at portions thereof close to said stays.
