Electrical contacting arrangement for piezoelectric multilayer actuator, has lead-like shaped part including lateral cross-beams having reciprocal breaking points in such manner that meander sections are formed

摘要

The arrangement has a lead-like shaped part (3) including a contacting base for a connection unit arranged on lateral outer contacting strips (2). The part is connected with the strips along a predominant or entire longitudinal axis line, in a material-fit manner. Lateral cross-beams of the part have reciprocal breaking points (4) in such a manner that meander sections are formed. The points are provided at the part or produced at preformed reference breakpoints, by thermal-mechanical stress or during continuous and alternative loadings in an actuator operation.
