NOISE-PROOF POWER SUPPLY BUS Russian patent published in 2024 - IPC H02G5/06 H01R4/58 H02B1/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to power supply of direct and/or alternating voltage with high currents from one and/or several sources to one and/or several electric power consumers. Noise-proof power supply bus includes a housing and an insulated conductor located inside in the form of a plate, which provides for the transmission of electric power. Due to the base U-shaped in the cross section and the cover in the form of a plate, which form a current-conducting bus for reverse currents and at the same time a housing, inside of which there is a current-conducting bus of direct currents, which allows generally reducing parasitic parameters due to decreasing linear inductance and increasing linear capacitance. For electrical connection to source and/or consumer of electrical energy of current-conducting buses in them there are recesses, in which flexible electric conductors are soldered, the opposite ends of which are soldered to lugs of one and/or group of electric connectors for connection to one and/or group of sources and/or consumers of electric energy. Assembled electric bus and flexible conductors are completely covered with metallised fabric having electric contact with casings of electric connectors, which provides resistance to electrostatic discharge. Between the current-conducting buses and the metallised fabric there are insulators from a group of dissimilar materials, including an oxide film, a lacquer and an adhesive film, which provides high electric strength. Formed air cavity between the current-conducting buses is filled with an electrically insulating material from fibreglass laminate and/or under pressure with an epoxy foam compound.

EFFECT: high electrical and mechanical strength of the power supply bus with low parasitic parameters and high resistance to external electromagnetic interference and electrostatic discharge.
