Device for the inductive transmission of electrical power
First Claim
1. A device for inductive transmission of electric energy, provided with a primary side power line comprising two wires deployed parallel to each other, wherein the power can be drawn by at least one mobile pick-up on a secondary side by means of inductive coupling along its energy path, wherein a data line, comprising two wires, deployed in parallel to each other on the primary side, is provided for additional inductive transmission of data to or from the pick-up, and wherein both wires of the data line are arranged adjacent to one of the wires of the power line and wherein they are deployed further away from the other wire of the power line, and wherein they are arranged symmetrically to a plane, to which the profile of the conductor of the adjacent wire of the power line is also symmetrical.

Abstract
The invention relates to a device for the inductive transmission of electrical power, comprising a power line which is situated on the primary side of said device and which consists of two wires which are guided in a parallel manner relative to each other. Power can be drawn from line by at least one mobile consumer, which is situated on the secondary side, by means of inductive coupling. Said device is provided with a data line which is situated on the primary side for the additional inductive transmission of data to and/or from the consumer. Said data line consists of two wires which are guided in a parallel manner relative to each other. Each of the data line wires is arranged adjacent to one of the two power line wires and in a manner that is symmetrical to a plane. The cross section of the conductor of the adjacent wire of the energy line is also symmetrical relative to the plane. The inductive coupling between the power line and the data line can be thus kept very low, and simultaneously enables the inductor, which is to be provided on the secondary side for the magnetic coupling with the data line, to be integrated into or mounted on the energy-transmitting consumer. The data line can be fixed to the power line or both lines can be integrated therewith in a common cable.

14. A cable for the primary conductor loop of a device for inductive transmission of electrical power at least to one mobile pick-up, having a conductor that is provided with an approximately symmetrical profile and surrounded by insulation, wherein for the purposes of simultaneous transfer of data to and/or from the pick-up, two other conductors having a significantly smaller profile are arranged parallel to the first conductor and symmetrically to plane of symmetry of its profile;
- and wherein the other conductors are also surrounded by insulation and tightly attached to the first conductor, and wherein the angular position of the two other conductors with respect to the first conductor is visible from outside by the form of the cable and/or by a marking.
