Abstract

A collector shoe for a collector with a carbon brush and a support has, between the carbon brush and supporting element, a galvanically applied metallic layer, which, at least at one end, either extends itself over the carbon brush at an angle, its extension which forms an angle being at least partially molded onto the supporting element or embedded into the latter and designed as an electrical connection element, or is linked with an electrical element which extends beyond the carbon brush, forms an angle and is similarly molded onto the supporting element or embedded in the latter. An advantageous process for producing said collector shoe consists producing the carbon brush with excess length, covering it in the metallic layer and then cutting it to length, and consequently bending the projecting metallic layer into the angular shape and embedding it in the directly molded-on supporting element of synthetic material.
