ABSTRACT:
The present disclosure is directed to connectors and methods for passing signals through capacitive coupling and electron tunneling. The connectors according to the present disclosure can include contacts that have a dielectric film or coating applied at least at a contact interface area where the contacts engage with the contacts of a complementary mating connector. The contacts of the either or both of the connector and complementary connector can be coated with a dielectric film. The dielectric film can be selected from metal oxides and can be applied using known methods such as vapor deposition methods, oxidative methods, plating methods and adhesive coating methods. Performance parameters such as capacitance and resistance can be selected by selecting the material for the film and the thickness of the dielectric film and provides a contrast between the requirements for high frequency signal transfer using capacitive coupling and electron tunneling versus traditional metallic contact.
