Connector assembly, electrical device and electrically conductive connection arrangement

By connecting an impedance element in series between the connector shielding layer and the device housing, the equivalent resistance of the circuit between the shielding layer and the device housing is adjusted, thus solving the problem of erosion caused by excessive induced current in the shielding wire. This enables flexible control of the induced current and avoids erosion and the generation of additional EMI noise.
