Publication number: 20230245819Abstract: A connection system for exchanging electrical signals, includes a first symmetrical connector, and a second symmetrical connector. Each symmetrical connector has at least one magnetic core provided with at least one turn. The symmetrical connectors are produced in a substrate made of insulating material so as to form a half of a coupling transformer At least one half of the coupling transformer of each connector is arranged opposite one another so as to be able to exchange a magnetic flux. The electrical signals are emitted by the first connector in the form of a magnetic flux, and the second connector generates the electrical signals on receiving the magnetic flux.Type: ApplicationFiled: May 20, 2021Publication date: August 3, 2023Applicant: SAFRAN ELECTRONICS & DEFENSEInventors: François GUILLOT, Patrice CHETANNEAU, Pascal SPOOR
