Problems solved by technology
[0002] At present, the ordinary cables used in electric vehicles have a relatively simple structure, and generally use PVC insulation and sheaths. However, due to the long-term outdoor movement of electric vehicles, the on-board pressure and friction of the cables are relatively large. Externally, the structure of the cable conductor is damaged, the electrical performance and the bending performance of the cable are reduced, and local damage is easily caused, and the slippage failure of the conductor at the damaged part eventually causes the cable to break at the end of the conductor here, resulting in cable failure. Issues such as reduced safety and reliability and shortened service life also affect the stability and safety of electric vehicles

Embodiment Construction
[0012] Such as figure 1 As shown, a kind of electric vehicle charging cable of the present invention comprises insulated wire cores, several insulated wire cores are wrapped with a braided shielding layer 2, and the braided shielding layer 2 is extruded with a polyurethane elastomer sheath 1, and the insulated wires The core includes a stranded conductor 6, a copper tape reinforced wrapping layer 5 extruded outside the stranded conductor 6, and a low-smoke zero-halogen irradiation cross-linked polyolefin insulating layer 4 extruded outside the copper strip reinforced wrapping layer 5, A polyvinyl chloride isolation layer 3 is filled between the insulated wire core and the braided shielding layer 2 .
[0013] The stranded conductor 6 is a bare copper or tinned stranded conductor 6, which can be designed according to the needs of softness, and the diameter and number of stranded monofilaments can be adjusted.
[0014] The copper strip reinforced wrapping layer 5 is a narrow co...

The invention discloses a cable for charging an electric automobile. The cable comprises a plurality of insulating wire cores outside which a woven shielding layer is lapped, wherein a polyurethane elastomer sheath layer is extruded outside the woven shielding layer; each insulating wire core comprises a stranded conductor, a copper strip reinforcing lapped layer and a low-smoke zero-halogen irradiation crosslinked polyolefin insulating layer; the copper strip reinforcing lapped layer is extruded outside the stranded conductor; the low-smoke zero-halogen irradiation crosslinked polyolefin insulating layer is extruded outside the copper strip reinforcing lapped layer; and the space between the insulating wire cores and the woven shielding layer is filled with a polyvinyl chloride isolatinglayer. The invention has the advantages that: the cable has a simple structure, is convenient to use, has high weather resistance and long life, is environmentally-friendly, can be used outdoors for a long time and works stably and reliably.
Description
technical field [0001] The invention relates to a cable, in particular to a cable for electric vehicle charging. Background technique [0002] At present, the ordinary cables used in electric vehicles have a relatively simple structure, and generally use PVC insulation and sheaths. However, due to the long-term outdoor movement of electric vehicles, the on-board pressure and friction of the cables are relatively large. Externally, the structure of the cable conductor is damaged, the electrical performance and the bending performance of the cable are reduced, and local damage is easily caused, and the slippage failure of the conductor at the damaged part eventually causes the cable to break at the end of the conductor here, resulting in cable failure. Issues such as reduced safety and reliability and shortened service life also affect the stability and safety of electric vehicles. Contents of the invention [0003] In order to solve the above technical deficiencies, the pr...
