Abstract:
1. A data and energy transmission system for passenger boarding bridges for airplanes of the type of those comprising a telescopic tunnel with variable length comprising at least said data and energy transmission system wherein it comprises at least a series of conductor rails insulated by means of an insulating casing, arranged along the inner section of the telescopic tunnel, on the outer surface of the latter, being electrically connected to the first structure, at least one pantograph mechanism electrically connecting the series of conductor rails with the second structure, which is in permanent contact with said conductor rails, sliding along such rails following the movement of the outer section of the telescopic tunnel with respect to the inner section during the extension and retraction of the telescopic tunnel, and data transmission means connected to the first structure and to the second structure, the sliding of the pantograph mechanism on the series of conductor rails allowing data and current transmission between the first structure and the second structure, said energy and data being transmitted from said first structure and second structure to the other points of the telescopic tunnel.
