Abstract: The present invention provides a differential paired cable with compensation functions, including: a first wire; a second wire; a first insulating layer; a second insulating layer; a ground wire; and a shielding layer. By controlling at least one of a length difference between the first insulating layer and the second insulating layer exposed outside of the shielding layer to be greater than 0.1 mm, a diameter difference between the first wire and the second wire to be greater than 0.005 mm, and a length difference between a welding portion of the first wire and a welding portion of the second wire to be greater than 0.05 mm, a signal transmission rate of one of the first wire and the second wire is compensated, so as to reduce an intra pair skew of the differential paired cable.

Abstract: A method for producing a cable by covering with polytetrafluoroethylene and extrusion molding with a perfluoroalkoxy compound, including: covering an outer surface of a conductor with an insulation layer; and extrusion molding a skin layer on an outer surface of the insulation layer to form a cable. The insulation layer and the skin layer are made of polytetrafluoroethylene and a perfluoroalkoxy compound, respectively. The perfluoroalkoxy compound and polytetrafluoroethylene both have high temperature resistance, good electronic signal transmitting performance, and non-bonding surface, etc., and the perfluoroalkoxy compound has a Shore hardness of 60 to 70D, which can impart the skin layer a certain hardness, and is suitable for being extrusion molded on the outer surface of the insulation layer made of polytetrafluoroethylene, so as to support the insulation layer and prevent the insulation layer from being deformed. Therefore, the perfluoroalkoxy compound is the most suitable material for the skin layer.

Abstract: A USB cable structure includes a cable body and a plurality of wires. The cable body extends a length along an axial direction and forms an inner space, and the inner space forms an elliptical cross-section in the radial section of the cable body perpendicular to the axial direction. The plurality of wires are arranged in the elliptical inner space of the cable body, and the diameter of the wire can be increased by the enlarged elliptical inner space to reduce the attenuation of the transmission signal, thereby extending the length of the transmission cable to transmit the signal to a longer distance without the assistance of the attenuation compensation chip.
