Problems solved by technology

After the wire is formed, there is almost no stretchability due to structural limitations. In the process of use, if there is a sudden external force, it is easy to cause damage to the wire or the solder joints at both ends fall off.
And when the use length exceeds the standard length of the wire itself, because the wire cannot be stretched, the wire cannot be used, and the user experience is poor

Abstract

The invention relates to a telescopic wire rod as well as a preparation method and application thereof. The telescopic wire rod comprises a rubber strip, a wire layer and a protective layer from inside to outside, the wire layer comprises wires and yarns; the wire and the yarn surround the rubber strip; the protection layer wraps the wire layer. The wire has extremely high telescopic performance, the wire can be prevented from being damaged by large external force in the using process, the service life of the wire is prolonged, and the using length of the wire can be increased in the using process.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a stretchable wire and its preparation method and application. Background technique [0002] At present, the common charging lines are mostly two-core or four-core twisted structure, that is, the copper material is twisted and covered with an insulating layer, two red and black core wires are twisted in pairs or four red and black core wires are twisted, and then directly covered with a The outer layer is layered. After the wire is formed, there is almost no stretching ability due to structural limitations. In the process of use, if a sudden external force is encountered, it is easy to cause damage to the wire or the solder joints at both ends fall off. And when the use length exceeds the standard length of the wire itself, because the wire cannot be stretched, the wire cannot be used, and the user experience is poor. [0003] At present, the retractable charging line is mainly ...
