Abstract

Electrical sliding contract is for electrical machines having a moving collector, which is transverse relative to the sliding contact. The contact has a conducting part which is applied to the collector (5) and is also connected to a fixed circuit of the machine. The conducting part (6) is contained in an envelope (8) which is positioned with respect to the collector. The conducting part has electrically conducting grains (11) and pressure means which act within the envelope (8) containing the grains, which maintains the grains in contact with each other and with the collector (5) surface. The pressure is sufficient to allow grains to be displaced with respect to each other, as well as with respect to the envelope (8) and collector (5).
