Abstract

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.
