1. A device for electrical energy supply and/or data supply of stationary end devices, that may transmit and/or receive data signals, using inductive coupling, comprising:

  • an oblong holding device;

    a number of end devices that may have different widths in the direction of longitudinal extension of the holding device and occur as narrow or wide end devices;

    wherein the holding device permits the end devices to be held lined up adjacent to one another, even with gaps therebetween, and to this end includes a support rail that permits free positionability of the end devices at any location along the support rail;

    a number of adjacently arranged transmitting coils along the holding device, wherein at least some of the transmitting coils have a dimension in the longitudinal direction of the holding device that is approximately the same as the width of narrow end devices;

    the transmitting coils are embodied for generating magnetic field lines with a useable portion parallel to the longitudinal extension of the holding device and may be switched individually or to create groups, wherein interconnecting results in virtually longer coils having a common magnetic field in order to be able to handle wider end devices;

    at least some of the end devices each have at least one receiving coil that spans a plane transverse to the usable portion of the magnetic field lines of the transmitting coils;

    the end devices with their receiving coils may be geometrically allocated to the individual transmitting coils or to transmitting coils switched in groups, in that electromagnetic couplings are used only between pre-determined transmitting coils and receiving coils for energy and/or data supply;

    wherein one or a plurality of the end devices is supplied with energy and/or data signals in a contactless manner by current application of individual transmitting coils or of interconnected transmitting coil groups.
