MULTI-CHANNEL CURRENT-COLLECTOR Russian patent published in 2018 - IPC H01R39/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to multi-channel current collector devices of miniature design. Multi-channel current collector device comprising several electrical circuits consists of housing and shaft coaxially disposed therein, on which set of alternating coaxial current collector rings and coaxial insulating washers is installed; between fixed outer and movable inner rings of each coaxial pair of current collector rings elastic conductor rings alternating with dielectric rollers are placed in contact with them; shaft is installed in housing by means of radial-thrust bearing located at one end of device, housing and shaft are made from aluminum, and dielectric cylindrical surfaces of housing and shaft, which are in contact with current collector rings, are formed by multilayer paint coatings with subsequent machining.

EFFECT: technical result is increase in efficiency, reliability, device resource increase and simplification of its manufacture.
