Abstract: A coupling device serves for the contact-free transmission of data signals between signal conductors of two signal lines with the aid of a coupling structure. At least one signal conductor is a signal core of a signal cable. Coupling portions of the two signal conductors are positioned parallel in relation to one another in a defined way with the aid of the coupling structure. At least a first signal conductor preferably being free from galvanically connected coupling elements lies in a coupling aid. The contact-free coupling dispenses with connecting additional coupling elements at the ends to a signal cable in an electrically conducting manner. By obviating the need for special connector fabrication, this achieves the effect of simplifying assembly and at the same time also improving data transmission reliability, since faults that occur for example in a crimping or soldering process are ruled out.
