New energy AC charging cable

Abstract

The invention discloses a new energy AC charging gun cable. The new energy AC charging gun cable comprises power transmission lines, a signal transmission line, auxiliary lines, a tissue layer and a TPE protection layer, wherein the three power transmission lines and one signal transmission line are symmetrically arranged in terms of centers of circles, the two auxiliary lines are symmetrically arranged at positions at the two sides of the signal transmission line, gaps among the power transmission lines, the signal transmission line and the auxiliary lines are filled with fillers to form a core wire, and the tissue layer and the TPE protection layer successively wrap the core wire from the inside to the outside. The structural design is ingenious and reasonable, a certain quantity of the power transmission lines, the signal transmission lines and the auxiliary line are arranged in a matched mode, various state parameters during charging can be conveniently detected in real time, timely charging safety information is provided, accurate control and safe correct operation of a whole charging process are effectively guaranteed, the flexibility is good, the integrated performance is excellent, the service life is long, and the interference immunity is high.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a new energy AC charging gun cable. Background technique [0002] Due to the wide range of energy sources, quiet running, and no pollution emissions, electric vehicles have attracted more and more attention from various automobile manufacturers, and they have launched household electric vehicles one after another. The charging gun is a necessary configuration for electric vehicles; the charging gun is connected to the charging device through a cable; when charging, it is necessary to perform real-time detection of various state parameters during charging to provide timely charging safety information, but the existing The simple structure of the cable cannot meet the above requirements, and the overall performance is poor, such as cold resistance, wear resistance, oil resistance, acid and alkali resistance, water resistance, UV resistance, external load pressure and therm...

Problems solved by technology

The charging gun is a necessary configuration for electric vehicles; the charging gun is connected to the charging device through a cable; when charging, it is necessary to perform real-time detection of various state parameters during charging to provide timely charging safety information, but the existing The simple structure of the cable cannot meet the above requirements, and the overall performance is poor, such as cold resistance, wear resistance, oil resistance, acid and alkali resistance, water resistance, UV resistance, external load pressure and thermal stress resistance. After repeated use for many times, the outer layer of the cable is easy to harden and detach, so that the conductor loses the protection of the insulating layer, resulting in unsafe factors such as leakage, short service life, and increased corresponding costs for cable replacement and maintenance. Use causes great inconvenience
