Title
(EN) Additional contact for an electric component and piezoelectric component in the form of a multilayer structure
(ZH) 用于电子元件以及多层结构压电元件的附加接通体
Abstract
(EN)
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).

一种用于多层结构压电元件(10)的附加接通体(30)以及这样一种元件(10),其中压电元件(10)由一个交替设置的压电陶瓷层和电极层构成的叠堆(17)构成。所述附加接通体(30)具有一个接通部件(31),它具有一个用于与电接头部件(20)连接的接通部位(33)以及一个用于与金属体(15,16)连接的固定部位(34)。为了能够使附加接通体(30)中的有害拉/压应力最小化,所述附加接通体(30)、尤其是所述接通部件(31)具有一个形状,通过它可以实现临界拉负荷的应力重新分布。这一点例如通过接通部件(31)里面的至少一个弯曲(32)实现。
