REVOLVING CONTACT DEVICE Russian patent published in 2003 - IPC

FIELD: current collecting devices. SUBSTANCE: contact device that can be use to transfer pulsed electric signals within comprehensive frequency band between source and receiver disposed in relatively rotating parts of equipment has contact ring made in the form of asymmetric transmission stripline having definite wave impedance. Newly introduced in device are two resistors arranged diametrically opposite to input, their ratings being equal to asymmetric stripline wave impedance. Insulating base together with contact ring and common wire serve as propagation medium for high-frequency components of pulsed signal. EFFECT: improved waveform of pulsed signal. 1 cl, 4 dwg
