1. A connection system for exchanging electrical signals, comprising a first symmetrical connector and a second symmetrical connector, each symmetrical connector comprising at least one magnetic core provided with at least one turn, the symmetrical connectors being produced in a substrate made of insulating material, so as to form a half of a coupling transformer, at least one half of a coupling transformer of each connector being disposed opposite to each other so as to exchange a magnetic flux, the electrical signals being emitted by the first connector in the form of a magnetic flux, the second connector generating the electrical signals on receiving the magnetic flux,
wherein a capacitive electrical shielding layer is disposed on a surface of the insulating substrate of each symmetrical connector, openings being formed in the shielding layer so as not to come into contact with the magnetic cores and so as to allow the passage of magnetic fluxes, the shielding layer being open between the different portions of the same magnetic core flush with the surface of a symmetrical connector so as not to create a parasitic turn creating a short circuit of the coupling transformer.
