Patent attributes
The present disclosure relates to the technical field of data cables, more particularly to a unidirectional free-pulling data cable that includes a first wire, a second wire and a hollow housing in which a wheel core, a follow-up circuit board, a clamping assembly, and a fixed conductive board disposed on one side of the housing corresponding to and electrically connected to the follow-up circuit board are arranged. The wheel core, with an elastic member disposed therein and a wheel cover disposed at the opposite side thereof, rotates relative to the housing. The first and second wires are exposed out of the housing partially. The clamping assembly cooperates with the wheel cover to position the wheel core to limit the rotation thereof, which solves the problem that the input and output ends of the existing telescopic data cable need to be stretched simultaneously when using, and is more convenient to use.
