An edge connector for connecting to a mating connector includes an outer conductor having a main body and plug-in portion, and first and second inner-conductor contacts arranged at least partly inside the outer conductor. The inner-conductor contacts each comprise a coupling end and a contact end. A shortest spacing between the coupling end and the contact end of the first inner-conductor contact is different from a shortest spacing between the coupling end and the second contact of the second inner-conductor contact. The overall electrical lengths of the inner-conductor contacts are the same. The contact ends are arranged in parallel on a main plane and in the plug-in portion. The inner-conductor contacts are arranged at least partly inside a receiving chamber of the main body. The main plane divides the receiving chamber into first and second asymmetric chamber portions. An insulator galvanically isolates the inner-conductor contacts from the outer conductor.
