Estimating the term…
The invention relates, inter alia, to an additional contact (30) for a piezoelectric component (10) in the form of a multilayer structure and to a corresponding component, wherein the piezoelectric component (10) is formed by a stack (17) of alternating piezoelectric ceramic layers and electrode layers. The additional contact (30) has a contact element (31) with a contact zone (33) for connection to an electrical connecting element (20) and with a fastening zone (34) for connection to a metallized part (15, 16). In order to minimize harmful tensile/pressure loads in the additional contact (30), the additional contact (30), especially the contact element (31), is shaped so as to allow for a load distribution of the critical tensile loads, for example by means of at least one bend (32) in the contact element (31).
An additional point of contact for an electric component, particularly for a piezoelectric component of multilayer construction, having an electrically conductive contact element (31) for connecting the electric component (10) to at least one electric connection element (20), characterized in that the contact element (31) has a shape which is or can be used to rearrange the stress of the critical tensile loads.
