METHOD OF ASSEMBLING DOUBLE-SIDED FLEXIBLE PRINTED CABLE WITH MODAL REDUNDANCY Russian patent published in 2024 - IPC H02H3/22 H04B15/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, specifically to methods of cable redundancy. For redundancy of flexible cables, support conductor is located on lower side, redundant and standby conductors are located to the left of it on upper and lower sides, wherein like redundant and standby conductors are arranged one above the other in dielectric layer. Attenuation of external conductive emissions is provided by arrangement, implying use of two additional signal conductors in flexible printed cable, which leads to amplification of electromagnetic coupling between signal conductors and excitation of a larger number of modes in the transmission line during pulse action supplied between the active and reference conductors. Increase in redundancy ratio is achieved due to introduction of additional signal conductor into configuration of flexible printed cable. In case of failure of the redundant circuit, a similar technical result will be achieved in the reserve circuit.

EFFECT: attenuation of external conductive emissions and increase of redundancy ratio.
