Abstract
The utility model discloses a special computer cable comprising a plurality of insulation intertwisted signal lines, a plurality of insulation intertwisted data lines and an insulation intertwisted power line. The plurality of insulation intertwisted signal lines, the plurality of insulation intertwisted data lines and the insulation intertwisted power line wraps the periphery of a reinforcement core to form a cable core. A elastic layer composed of polyurethane elastomers wraps the outside of the reinforcement core. The insulation intertwisted power line penetrates among the plurality of insulation intertwisted signal lines. A sub-shielding layer wraps the outside of the insulation intertwisted power line. A taped wrapping layer, an overall shielding layer and a flame retardation polyurethane sheath layer sequentially wrap the outside of the cable core. The special computer cable has characteristics of being high in mechanical strength, being tensile, flame retarding, soft, cold resistant, chemical corrosion-resistant, and being small in attenuation and high in transmission performance. The special computer cable also has characteristics that the special computer cable can well prevent interferences by electromagnetic waves and crosstalk between wire pairs, etc. Especially the special computer cable which integrates data signals, simulation signals and a power supply provides convenience for the usage and enables laying space to be reduced.
