CURRENT-COLLECTING DEVICE Russian patent published in 2014 - IPC H01R39/00 

FIELD: electricity.

SUBSTANCE: invention relates to current-collecting devices, providing for transmission of electric DC, AC and pulse signals in wide range of frequencies and capacities between a source and a receiver, arranged in mutually rotating parts of an object, and may be used in electric engineering, control systems, radar location, for information coding. The device comprises a stator of a current-collecting device, made of dielectric rings with adhered contact surfaces from electroconducting material, along which current-collecting bars fixed on rotor rings slide. Rings of the stator and rotor form rotary electric connections. A set of rings with current-conducting wires is in a dust-moist-proof body filled with a lubricant dielectric liquid. Packets of rings are combined into groups by types of transmitted signals and placed into a set depending on their capacity and range of frequencies.

EFFECT: reduced electric interference from power signals with width-pulse modulation transmitted by power lines and increased resistance to electric leaks and breakthroughs.
