Title: Erhard Grohs: Innovator in Electrical Conductivity
Introduction
Erhard Grohs is a notable inventor based in Oberursel, Germany. He has made significant contributions to the field of electrical conductivity through his innovative patents. With a total of 2 patents, Grohs has focused on developing advanced materials and processes that enhance the performance of electrical components.
Latest Patents
One of Grohs' latest patents is a process for the production of multi-layered brushes. This process involves charging a mould with at least one electrically conductive powder and compressing the contents to form a crude brush. The heat treatment of the crude brush and the fixing of the ends of the electrical conductors are also key steps in this innovative process. The method is characterized by the simultaneous introduction of at least two conductive powders to create a brush formed by integral blocks, optimizing the junction between these blocks in the compression direction.
Another significant patent by Grohs is a sliding contact member designed for high current densities. This member is notable for being free of toxic metals such as lead and antimony. It includes copper, carbon, and an added material selected from metals or metal alloys with a melting temperature substantially below that of copper. This design ensures that the sliding contact member is electrically conductive and capable of carrying high current densities while promoting cooling and good slidability against a mating contact member.
