    • The invention concerns a device for connecting vibrating components having different electric potentials, in particular for connecting a stator housing (8) for an electric motor (1) with a housing (4) for control electronics (6) inside a clutch actuator of a motor vehicle, containing electrical contact means (30) for establishing an electrically conductive connection between the components, and means (26) for establishing its mechanical connection. The invention provides that the means for establishing the mechanical connection have at least one plastic ring (26) held in an opening (16) of a first component (2, 4, 6) and a neck-shaped attachment segment (14) formed in a second component (1, 8), whereby, by pushing the neck-shaped attachment segment (14) of the second component (1, 8) into the opening (16) of the first component (2, 4, 6), the plastic ring (26) can be compressed in the radial direction, forming a non-positive connection between the two components, and, simultaneously, the electrical contact means (30) can be engaged with each other.
    • 本发明涉及用于连接具有不同电位的振动部件的装置,特别是用于将用于电动机(1)的定子壳体(8)与电动机的离合器致动器内的控制电子装置(6)连接的壳体(4) 车辆,包含用于在所述部件之间建立导电连接的电接触装置(30),以及用于建立其机械连接的装置(26)。本发明提供用于建立机械连接的装置具有至少一个塑料环(26) 保持在形成在第二部件(1,8)中的第一部件(2,4,6)和颈部附接部分(14)的开口(16)中,由此通过将颈部附接部分 第二部件(1,8)的第二部件(14)插入到第一部件(2,4,6)的开口(16)中,塑料环(26)可以沿径向方向被压缩,从而在第二部件 两个组成部分,同时, 电接触装置(30)可彼此接合。
