Description

Technical Field

[0001] This application relates to the field of power cables, specifically to an EY insulated thermoplastic elastomer sheathed AC charging pile cable for new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, AC charging piles, as one of the main charging devices for electric vehicles, are facing increasingly stringent performance requirements for their supporting cables. Traditional cables have several shortcomings when used in AC charging piles. For example, existing cables have limited insulation performance, making them susceptible to degradation due to external environmental factors such as temperature changes and humidity during long-term use, posing safety hazards. Furthermore, their lack of flexibility makes them difficult to bend and route during installation and use, increasing construction difficulty and costs. In addition, the abrasion resistance and weather resistance of cables need improvement to adapt to complex outdoor environments. Utility Model Content

[0003] The purpose of this application is to provide an EY insulated thermoplastic elastomer sheathed AC charging pile cable for new energy vehicles, so as to solve the problems of limited insulation performance, insufficient flexibility, poor wear resistance and weather resistance of existing AC charging pile cables mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] This application provides an EY insulated thermoplastic elastomer sheathed AC charging pile cable for new energy vehicles, including a cable core. The cable core includes multiple stranded conductors, and each conductor is wrapped with an inner insulation layer and a shielding layer in sequence. A filler layer is provided outside the cable core, and an outer insulation layer is wrapped outside the filler layer. A sheath layer is provided outside the outer insulation layer.

[0006] Furthermore, the conductor is made of multiple strands of oxygen-free copper wire, the diameter of which is 0.1-0.3 mm, and the stranding pitch of the multiple strands is 10-20 mm. Using multiple strands of oxygen-free copper wire improves the conductivity and flexibility of the cable.

[0007] Furthermore, the inner insulation layer is made of ethylene propylene rubber with a thickness of 0.8-1.2 mm. Ethylene propylene rubber has excellent insulation properties, weather resistance, and flexibility, which can effectively protect the conductor and improve the overall insulation performance of the cable.

[0008] Furthermore, the shielding layer is tin-plated.

[0009] The copper wire braided shielding layer has a braiding density of no less than 85%. This layer effectively shields against external electromagnetic interference, improving the cable's anti-interference capability and ensuring the stability of the transmitted signals.

[0010] Furthermore, the filling layer is filled with polypropylene rope, with a filling rate of not less than 90%. Polypropylene rope filling can ensure the stability of the cable structure, reduce the shaking of the cable core inside the cable, and also help improve the flexibility of the cable.

[0011] Furthermore, the outer insulation layer is made of thermoplastic polyurethane elastomer (TPU) with a thickness of 1.5-2.0 mm. TPU has good insulation properties, abrasion resistance, and flexibility, which can further enhance the insulation effect of the cable, while improving the cable's abrasion resistance and resistance to mechanical damage.

[0012] Furthermore, the sheath layer is made of thermoplastic elastomer (TPE) with a thickness of 2.0-2.5mm. The TPE sheath has excellent weather resistance, flexibility, and abrasion resistance, enabling it to adapt to various complex outdoor environments, effectively protecting the internal structure of the cable and extending its service life.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention improves the conductivity and flexibility of the cable by using a conductor made of multiple strands of oxygen-free copper wire; the inner insulation layer is made of ethylene propylene rubber and the outer insulation layer is made of TPU. This double insulation structure greatly improves the insulation performance of the cable and reduces safety hazards caused by a decline in insulation performance.

[0015] The cable is equipped with a copper wire braided shielding layer, which effectively shields against external electromagnetic interference and ensures the stability of the cable's signal transmission, making it suitable for charging scenarios with high requirements for the electromagnetic environment.
