Description

Technical Field

[0001] This application belongs to the field of charging cable manufacturing technology, specifically relating to an environmentally friendly luminous AC charging cable for new energy vehicles. Background Technology

[0002] In the existing technology, the existing AC charging cables for new energy vehicles are mainly used to provide charging services for electric vehicles. These cables are usually made of ordinary materials and do not have special optical or alarm functions. However, in daily use, especially at night or in low-light environments, the charging status of ordinary cables is not easy to detect, which poses a safety hazard. In addition, when the cable is dragged on the ground, it is easy for the cable to be hit by pedestrians or vehicles, which can damage the cable itself or the charging gun and charging connection device connected to it, thereby affecting the overall service life and safety of the charging equipment.

[0003] In current technology, electric vehicle users often choose to slow charge overnight, with charging times ranging from tens of minutes to up to ten hours. Furthermore, electric vehicle charging stations are mostly located in high-traffic, unattended locations such as underground parking garages, commercial centers, and businesses. The charging cables are long, posing a tripping hazard in poor lighting conditions, especially at night, where there are no clear warnings, leading to charging interruptions or accidents. In addition, the current charging status can only be displayed on the instrument panel, not directly on the cable, which is inconvenient, lacks intuitiveness, and increases the risk of human error causing charging interruptions or accidents. The high risk and poor user experience necessitate urgent improvements. Utility Model Content

[0019] This application provides an environmentally friendly luminescent AC charging cable for new energy vehicles, comprising multiple cores, a wrapping layer covering the outer periphery of each core, a sheath layer covering the wrapping layer, and a luminescent indicator line group disposed between the wrapping layer and the cores. The luminescent indicator line group includes a first luminescent line and a second luminescent line. By setting the first and second luminescent lines, when the cable is energized, the first luminescent line emits a first light signal; when the cable is not energized, the second luminescent line emits a second light signal.

[0020] In this embodiment, the wire core 1 includes a conductor 10 and an insulating layer 11 covering the outer periphery of the conductor 10. The conductor 10 is made of a type VI copper conductor, and the insulating layer 11 is made of a thermoplastic elastomer.

[0021] In actual implementation, by selecting Class VI copper conductors, which have thinner conductor filaments and more strands, the finished conductor is more flexible, easier to bend, and has a longer bending life; the bulletproof wire has excellent tensile strength and can withstand frequent torsion and bending environments, thereby extending its service life; the copper foil wire has good flexibility and elasticity, making the conductor less prone to breakage when bent, thus improving overall durability.

[0022] In practical implementation, the use of thermoplastic elastomers as insulation layers has the following advantages: First, thermoplastic elastomers have excellent insulation resistance performance, which can effectively protect the electrical performance of wires and cables and ensure the stability and safety of current transmission.

The value of N is a positive integer ranging from 2 to 33. For example, the value of N is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33.

[0028] In this embodiment, a filling layer 5 is provided between the wrapping layer 2 and the core wire 1, and the filling layer 5 is made of transparent PP rope.

[0029] In practical implementation, using transparent PP rope as a filler layer has the following advantages:

[0030] Firstly, PP rope has high strength and good abrasion resistance, which can improve the compressive strength and bending resistance of the cable;

[0031] Secondly, PP material has good electrical insulation properties, which makes its insulation performance unaffected by humidity when used in signal transmission cables;

[0032] Thirdly, PP material has low density but high strength, which helps to reduce the overall weight of the cable.

[0033] In this embodiment, the material of the wrapping layer 2 is transparent Mylar tape.

[0034] In actual implementation, the use of Louming Myla tape has the following advantages: Myla tape has excellent tensile strength, which can effectively prevent cables from loosening.

[0035] In this embodiment, the thickness of the sheath layer 3 is greater than the thickness of the wrapping layer 2, and the thickness of the sheath layer 3 is 3-5 times the thickness of the wrapping layer 2.

[0036] In this embodiment, the thickness of the sheath layer 3 is 0.5cm-1.8cm.

[0037] In this embodiment, the sheath layer 3 is made of transparent TPU.

[0038] In practical implementation, using transparent TPU as the sheath layer has the following advantages:

[0039] Firstly, TPU has high strength, abrasion resistance, tear resistance and impact resistance, tensile strength above 25 MPa, elongation exceeding 500%, and good load-bearing capacity and shock absorption performance.

[0040] Secondly, TPU is resistant to oil stains, water, acid and alkali corrosion, heat, aging, and low temperatures, and can remain stable in various harsh environments.

[0041] Thirdly, TPU has excellent insulation properties, which can effectively protect wires and cables from external environmental corrosion and extend their service life.

[0042] In this embodiment, the first light signal is a green light signal and the second light signal is a red light signal.
