MULTICHANNEL ROTATING LIQUID CURRENT COLLECTOR Russian patent published in 2022 - IPC H01R39/00 

FIELD: radar ranging.

SUBSTANCE: invention relates to multichannel current-collecting devices and can be used for simultaneous reception/transmission of electric signals of different frequency and power, including digital interfacing signals, as well as supply voltages of direct and alternating current from moving part of antennas to fixed part of antenna-feeder paths of radar stations both civil and military purposes. Multichannel rotating liquid current collector is a metal housing with a cover, inside which there is a contact column installed on bearing supports, consisting of contact pairs (contact rings), connected by means of wires and cables with external and internal electric connectors. Structural implementation of differential circuits enables to provide noise-immune high-speed transmission of a signal in digital form, and connection of high-frequency contact rings in two points spaced relative to each other by 180°, by means of dividers and matching transformers stability of transmission coefficient during rotation of current collector during transmission of high-frequency signals with operating frequency of 120 MHz.

EFFECT: technical result is expansion of functional capabilities of multichannel current collector by increasing maximum operating frequency to 120 MHz, minimizing signal losses, providing noise-immune high-speed signal transmission in digital form, which leads to improvement of technical and operational characteristics of the product as a whole.
