The invention discloses a stretch- and fatigue-resistant shielding
soft data cable which comprises eight
metal conductor units and an
aramid reinforcement element, wherein the
metal conductor units comprise
aramid fiber arranged at the centers, inner conducting
layers and outer conductor
layers; four symmetric insulated wire pairs are twisted around the outer surface of the
aramid reinforcement element to form a cable core; a second
polytetrafluoroethylene layer longitudinally wraps the outer surface of the cable core, gaps between the second
polytetrafluoroethylene layer and the four symmetric insulated wire pairs are filled with a plurality of cotton yarns, a cotton
fiber thread is wound around the outer surface of the second
polytetrafluoroethylene layer to form a buffer sliding layer, the winding direction of the cotton
fiber thread is opposite to the twisting direction of the four symmetric insulated wire pairs, a plurality of
metal wires are wound around the outer surface of the buffer sliding layer in parallel to form a metal shielding layer, the winding direction of the metal wires in the metal shielding layer is opposite to that of the cotton fiber thread, and a third polytetrafluoroethylene layer wraps the outer surface of the metal shielding layer. The stretch- and fatigue-resistant shielding
soft data cable has the advantages of
low friction coefficient, softness, stretch resistance and no friction static generation, and stable structural and
electrical performance after frequent moving still can be guaranteed.
