Patent attributes
The invention relates to an electric connecting device, especially for arrangement between a steering wheel and a steering column switch module of a motor vehicle, comprising a stationary housing part and a rotationable housing part which respectively include a connecting unit and enclose at least one spiral-shaped wound-up, flexible electric conductor whose respective end is connected to the connecting unit and which is guided in a reverse-direction loop inside the housing. The conductor is associated with a forced guidance element in a positive fit, engaging the peripheral side of the conductor and resulting in a defined winding or unwinding of the conductor during a rotational movement of the rotationable housing part. The forced guidance element comprises a toothing that engages into the respective recesses in the conductor and may be assigned to the rotatable housing part, the stationary housing part, or both.
