<p>The invention relates to means for guided, unidirectional or bi-directional transmission of electrical signals between a primary module (2) and a secondary module (3), incorporated in a vehicle steering wheel, by way of a two-wire line (18a, 18b; 18c, 18d). To be able to separate the primary module (2) and the secondary module (3), the primary two-wire line (18a, 18b) and the secondary two-wire line (18c, 18d) are terminated by a primary (12) or a secondary winding element (14) respectively which can be coupled to each other in the manner of a transformer by way of an air-gap (18; 18'). A primary shell-type core (11) holds the primary winding element (12), has a central opening (20) for the passage of a steering column supporting the steering wheel, and is substantially rotationally symmetrical to the axis (A) of symmetry of this central opening (20). The primary winding element (12) and the secondary winding element (14) are in the form of a toroid, the secondary winding element (14) is concentric to the primary winding element (12), and one receiving chamber (15) formed by the primary shell-type cores (11) and the secondary shell-type cores (13) holds the two winding elements (12, 14).</p> |
