专利汇可以提供Supporting means for piezoelectric transformers专利检索，专利查询，专利分析的服务。并且In a piezoelectric transformer comprising a ceramic body in the form of an elongate plate of piezoelectric material with one half polarized in the direction of thickness and the remaining half in the longitudinal direction, a pair of input electrodes secured to the opposite sides of said one half and an output electrode secured to the end surface of the remaining half, there is provided supporting means including means for mechanically clamping and supporting the piezoelectric transformer at at least one of the transverse line nodes of the longitudinal mechanical vibrational movement thereof which support permits free longitudinal vibrations while suppressing undesirable vibrating modes.，下面是Supporting means for piezoelectric transformers专利的具体信息内容。

权利要求

1. A piezoelectric power transformer comprising a ceramic body in the form of an elongated rectangular plate of piezoelectric material, one half of the length of said ceramic body being polarized in the direction of thickness of said ceramic body, the remaining half being polarized in the longitudinal direction, a pair of constraint-free input electrodes substantially coextensive with and secured to the opposite sides of said one half of said ceramic body, an output electrode secured to the end surface of said remaining half, and supporting means including only a constraining transverse linear mechanical support at at least one of the transverse nodal lines of the longitudinal mechanical vibrational movement of said piezoelectric transformer, said transverse linear mechanical support applying transverse constraining forces to opposite surfaces of said ceramic body at said nodal lines sufficient to suppress undesirable transverse vibration modes without interferring with said longitudinal mechanical vibrational movement.

2. The transformer according to claim 1 in which said supporting means comprises at least one rigid insulator frame fitted about said piezoelectric transformer at said transverse nodal line and with minimal width in the direction of the longitudinal vibrational movement of said piezoelectric transformer, and means adjustably connecting opposite sides of said frame for applying said constraining forces.

3. The transformer according to claim 1 in which said supporting means comprises at least one insulative elastic band fitted about said ceramic body at said transverse nodal line of the longitudinal mechanical vibrational movement of said piezoelectric transformer and stationary means for mechanically supporting opposite sides of said elastic band.

4. Apparatus according to claim 3 wherein said ceramic body is formed with a pair of projections projecting from opposite surfaces thereof on said nodal line and said projections are received within said insulative elastic band extending transversely of said ceramic body.

5. Apparatus according to claim 2 in which said rigid frame comprises a pair of insulative rigid members extending transversely of said ceramic body at the nodal line of the longitudinal mechanical vibrational movement of said piezoelectric transformer and clamping screw means for clamping opposite ends of said pair of insulative rigid members.
