Gear type anti-twisting soft charging wire for new energy automobile

Abstract

The invention discloses a gear type torsion-resistant soft charging wire for a new energy automobile, and the charging wire comprises a cable core, a wrapping tape and a sheath, wherein the wrapping tape wraps the cable core, the sheath is arranged outside the wrapping tape in an injection molding and sleeving manner, gear type axial vertical stripes are arranged outside the sheath, and the gear type axial vertical stripes are spirally distributed on the outer surface of the sheath; and a filler is filled between the cable core and the wrapping tape. The invention relates to the technical field of cables. According to the gear-type anti-twisting soft charging wire for the new energy automobile, the uniform gear-type axial vertical stripes are additionally arranged on the outer side of thesheath; when the wire is twisted in the using process, the gear-type axial vertical stripes on the outer side of the sheath offset or weaken radial twisting force, and the phenomena that a cable coreis twisted, bulges and the like are prevented; the processing and production difficulty is not increased, and no new risk is brought; meanwhile, the isolation layer of the cable core and the sheath ismade of non-woven fabrics and the like, so the charging wire is safe and environment-friendly; better heat dissipation can be realized, and the temperature rise of the wire rod is favorably reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a gear-type torsion-resistant and soft charging cable for new energy vehicles. Background technique [0002] Chinese patent CN106024150B discloses a new energy AC charging gun cable, which includes a power transmission line, a signal transmission line, an auxiliary line, a tissue layer and a TPE protective layer. Three power transmission lines and a signal transmission line are arranged symmetrically around the center of the circle, and two auxiliary lines Symmetrically arranged on both sides of the signal transmission line, the gap between the power transmission line, signal transmission line and auxiliary line is filled with fillers to form a core wire, and the tissue paper layer and TPE protective layer are covered on the core wire in sequence from the inside to the outside superior. The charging gun cable of this patent belongs to a solid structure cable, and the same as the ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a gear-type anti-twisting soft charging cable for new energy vehicles, which solves the problems of the existing new energy charging cables such as easy twisting and swelling, and the temperature rise of the wire will be relatively low. Elevated, easy to burn the line; the existing solid structure charging line has high requirements on the concentricity of the sheath, which increases the manufacturing cost, and the use of talcum powder cannot meet the requirements of the clean room, and the solid structure is only suitable for AC small The problem with the diameter of the charging cable
