Title: Rudolf Schnabl: Innovator in Electrical Contact Technology
Introduction
Rudolf Schnabl is a notable inventor based in Rodenbach, Germany. He has made significant contributions to the field of electrical contacts, holding a total of 3 patents. His innovative approaches have advanced the technology used in electrical connections, particularly through unique welding processes and laminated materials.
Latest Patents
One of Schnabl's latest patents involves a welding process that utilizes an intermediate material in the form of a metal strip. This strip features a projection on the bottom surface of its core area, which is designed to join with a contact carrier strip made of copper or a copper alloy. The bottom surface of the strip is plated with a silver-based material, ensuring that the melting point of the core area exceeds that of silver. This process allows for the creation of a semifinished product for electrical contacts by welding the silver-coated surface to the copper contact carrier strip. The resulting alloy closely resembles the eutectic alloy with 28 wt. % of copper and the remainder being silver.
Another significant patent focuses on a laminated material for electrical contacts. This material consists of a support made from base metal or a base metal alloy, topped with a contact layer of titanium nitride. This layer is further covered with a mixed layer of titanium nitride and at least one noble metal. The method for producing this laminated material is accomplished in a single step within a vacuum apparatus, utilizing reactive formation of titanium nitride.
