An electric signal adapting device includes at least one first adapting interface and at least one first adaptor. The at least one first adapting interface comprises a magnetic component and a magnetic sensing component. The first adaptor is placed in correspondence with the first adapting interface. The first adaptor is electrically connected to each of the corresponding at least one first adapting interface for transferring the DC electric signal and connecting the DC electric signal to an external device. The magnetic component is configured to attract the at least one first adaptor. The magnetic sensing component is configured to determine whether the at least one first adaptor is correctly placed. When the magnetic sensing component determines that the at least one first adaptor is correctly placed, the at least one first adapting interface transfers the DC electric signal to the at least one first adaptor.

An electrical multi-conductor cable comprising a plug-in connector, in particular a line with a charging plug for electric vehicles. The cable has a central cable core, a number of conductors which are arranged concentrically in relation to one another in a ring around the cable core and are composed of individual wires, and in each case one insulation between the conductors. According to the invention, the contact apparatus has two clamping shell parts which, on the inner side thereof, have a plurality of receptacles which are radially stepped from one another. In each case one contact body is received in the receptacles of a clamping shell part and makes contact with one of the concentric conductors. Each contact body has a channel shape with a longitudinal extent and a curved cross-sectional profile around an associated conductor. A closure connects the clamping shell parts and fastens said clamping shell parts in the closed position, wherein the clamping shell parts coaxially hold the contact bodies and press each contact body against the respectively associated concentric conductor for contact-making purposes.
