USB data line structure capable of long-distance stable transmission

Abstract

The utility model relates to data transmission technical field, specifically including the conductor assembly, shielding layer, insulating layer and outer sheath that set successively from inside to outside, the conductor assembly includes at least two transmission core wires and a ground core wire, and each transmission core wire is by multiple silver plated copper core strands and is made, and the strand number is 16 24, and single copper core diameter is 0.08 0.12mm, shielding layer is the composite structure, including the aluminium foil shielding layer of inner layer and the braided shielding layer of outer layer, and the thickness of aluminium foil shielding layer is 0.02 0.04mm, and the braided shielding layer adopts the braiding of tinned copper wire and is made. The utility model discloses by setting up by multiple silver plated copper core strands and is made and the transmission core wire structure of optimization twisted parameter (pitch 8 12mm, adjacent reverse twisting), replaces the signal amplification function of multiple amplifiers in the prior art, realizes long distance transmission signal low attenuation, low crosstalk effect at the same time, avoids the data line structure complex problem caused by the amplifier setting, and simplifies the overall structure design.
