Problems solved by technology

[0003] 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

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 The electric vehicle charging cable shown includes a cable core, and the cable core is formed by twisting a plurality of main cores and a signal core, and a glass fiber filling rope 5 is filled in the gap of the cable core. Two layers of glass fiber wrapping tape 6 are wrapped around the outside, and the glass fiber wrapping tape is extruded and wrapped with a thermoplastic elastomer outer sheath 7; body insulation layer 2; the signal core is composed of six types of stranded copper conductors, a thermoplastic elastomer insulation layer extruded outside the six types of stranded copper conductors, and a copper wire shielding layer braided outside the thermoplastic elastomer insulation layer 3 and a thermoplastic elastomer inner sheath 4 extruded outside the copper wire shielding layer.

[0015] In order to improve the roundness of th...

Abstract

The invention discloses a charging cable of an electric automobile. The charging cable includes a cable core formed by pair twisting of a plurality of main wire cores and a signal wire core. Gaps of the cable core are filled with glass filament filling ropes. The cable core is coiled with two layers of glass filament belts. A thermoplastic elastomer outer sheath is formed outside the glass filament belts through extrusion. The main wire cores are composed of six types of twisted copper conductors and thermoplastic elastomer insulation layers extruded outside the six types of twisted copper conductors. The signal line is composed of six types of twisted copper conductors, a thermoplastic elastomer insulation layer extruded outside the six types of twisted copper conductors, a copper wire shielding layer braided outside thermoplastic elastomer insulation layer and a thermoplastic elastomer inner sheath extruded outside the copper wire shielding layer. According to the invention, the working efficiency of the cable is improved, the service lifetime of the cable is prolonged; environment friendliness is improved; mounting performance is improved; bending performance is improved; the mechanical performance is good; and use of a cable drag chain is facilitated.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to an electric vehicle charging cable. Background technique [0002] At present, in the charging field of new energy electric vehicles, the existing charging piles have low charging efficiency and long charging time. In order to better respond to my country's "13th Five-Year Plan" for the development of new energy electric vehicles. In order to improve the charging efficiency and shorten the charging time, low-voltage DC and high current are used to charge the battery of new energy vehicles. The charging pile gun cable plays a very important role as the connection link with the vehicle's energy storage. [0003] 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 lar...
