More particularly, the present invention relates to a device having an electroceramic device having a first electrical contact provided on a first side surface of the electroceramic device. A second electrical contact is provided on a second side surface of the electroceramic device.
- Electroceramic components for example piezoelectric transformers (PT) are known from the prior art, for example from US Pat. No. 2,830,274 A from 1958 to Charles A. Rosen.
- a piezoelectric transformer is an electromechanical resonance transformer that uses a combination of the inverse piezoelectric effect (excitation) and direct piezoelectric effect (voltage generation) to convert an input voltage with a given transformation ratio into one
- Frequency and transmission ratio are determined by the dimensions and the electromechanical material properties.
- piezoelectric transformers are operated with an electrical driver chip which impresses electrical excitation in a suitable resonant mode. Areas of application are, for example, the generation of a high voltage for the supply of fluorescent tubes.

- the electroceramic component To operate the transformer safely and efficiently, the electroceramic component must be securely contacted and positioned so that the quality of the resonance is minimized as much as possible. In addition, the power loss should be sufficiently dissipated and it must be created a way to hold the component, clamp or assemble.
- EP 0 814 518 B1 discloses a simple outer insulation structure which is intended to partially create the above favorable conditions.
