[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a cable for an intelligent charging pile, comprising:

[0025] A wire fixing frame 1, three groups of cables 2 are evenly arranged on the outside of the wire fixing frame 1, three groups of filling pads 3 are evenly arranged on the outside of the wire fixing frame 1, a braided layer 4 is arranged on the outside of the braided layer 4, an inner sheath layer 5 is arranged on the outside of the inner sheath layer 5, and an outer sheath layer 7 is arranged on the outside of the shielding layer 6.

[0026] Furthermore, three groups of installation grooves are evenly opened on the outside of the wire fixing frame 1, and the three groups of installation grooves match the cable 2. The wire fixing frame 1 and the filling pad 3 are both set to rubber material. The cable 2 can be installed in the installation groove opened in the wire fixing frame 1, and then the wire fixing frame 1 is restored by the rubber material to fix the cable 2. Then, the filling layer is used to reduce the gap between the wire fixing frame 1 and the braided layer 4 to prevent the cable 2 from moving.

[0027] Furthermore, the braided layer 4 is configured as a mesh structure, and the braided layer 4 is made of synthetic fiber material. The mesh structure of the braided layer 4 has better flexibility and elasticity, and can adapt to the bending and twisting of the cable, thereby reducing the mechanical stress on the cable and improving the durability and reliability of the cable. Synthetic fibers generally have better insulation properties, which can effectively isolate the conductors inside the cable from the external environment, and reduce electromagnetic interference and signal leakage.

[0028] Furthermore, the inner sheath layer 5 is wrapped around the outside of the braided layer 4, and the inner sheath layer 5 is made of polyvinyl chloride, which has good electrical insulation properties, can effectively block current conduction and leakage, and protect the conductor inside the cable from the influence of the external environment. Polyvinyl chloride is a material that is resistant to acids, alkalis, oils and other chemicals, so that the cable can still maintain stable working performance in harsh environments. Polyvinyl chloride has excellent waterproof properties and can effectively prevent moisture from penetrating into the cable, thereby reducing the risk of cable damage. Polyvinyl chloride has good tensile strength and mechanical properties, so that the cable can withstand a certain amount of tension and pressure, thereby increasing the service life of the cable.

[0029] Furthermore, the shielding layer 6 is configured as an aluminum alloy belt layer 61 and a galvanized steel belt layer 62, and the aluminum alloy belt layer 61 is wrapped around the outside of the galvanized steel belt layer 62. This structure has a double shielding layer, namely, an aluminum alloy belt and a galvanized steel belt. The aluminum alloy belt provides a higher electromagnetic shielding effect and can effectively block the entry of external electromagnetic interference, while the galvanized steel belt further enhances the shielding performance and reduces electromagnetic leakage and interference.

[0030] Furthermore, the outer sheath layer 7 is made of polyethylene. Polyvinyl chloride is corrosion-resistant. Polyethylene has good acid and alkali resistance and corrosion resistance. It can maintain the service life of the cable for a long time under harsh environmental conditions and is less likely to be eaten by insects. Compared with other materials, polyethylene has a lower density. Therefore, the use of polyethylene in the cable outer sheath layer 7 can reduce the weight of the entire cable, thereby reducing the cost of transportation and installation.

[0031] Furthermore, metering grooves are evenly arranged on the outside of the outer sheath layer 7, and the spacing between the metering grooves is set to 50 cm. The outer surface of the outer sheath layer 7 is evenly provided with grooves. The presence of the grooves can increase the flexibility of the cable, making it easier to bend and fold. The grooves can help the cable move more freely when bending and twisting, thereby increasing the flexibility of the cable, which makes the cable easier to install and use in complex charging equipment layouts and small spaces. The grooves can increase the friction resistance of the cable surface and reduce the impact of external impact and wear on the cable, which helps to extend the service life of the cable and reduce the frequency of maintenance and replacement.

[0032] Furthermore, a stretching ring 8 is provided at the front end of the outer sheath layer 7, and stretching ring grooves are evenly provided on the inner and outer sides of the stretching ring 8. The presence of the stretching ring 8 can effectively disperse the pulling force to avoid damage to the cable caused by local excessive pulling force. It can effectively prevent the plug from accidentally falling off or loosening during use, and avoid safety problems such as cable disconnection or short circuit. The stretching ring groove can reduce the stress concentration at the connection between the front end of the cable and the plug, and disperse the pressure on the connection point, which helps to extend the service life of the cable and the plug, and reduce the risk of damage caused by long-term use or frequent plugging and unplugging.

[0033] Working principle: The wire frame 1 supports and protects the cable. It is a rigid frame that provides physical support on the outside of the cable to ensure that the cable will not be subjected to external pressure or damage. On the outside of the wire frame 1, three groups of cables 2 are evenly arranged. These cables 2 may include power lines, signal lines or communication lines, etc., and are arranged according to needs. The cables 2 provide functions such as data transmission and power transmission. Between the cables 2, the filling pad 3 fills the gap to increase the stability of the wire frame 1 and prevent the cables 2 from interfering with or colliding with each other. A braided layer 4 is arranged on the outside of the cable. The braided layer 4 provides electromagnetic shielding and mechanical protection to reduce the impact of external electromagnetic interference on the cable 2. On the outside of the braided layer 4, the cable is provided with an inner sheath layer 5. The inner sheath layer 5 is usually made of durable materials such as polyethylene to provide additional protection and waterproofing. On the outside of the inner sheath layer 5, the cable is provided with a shielding layer 6, which is mainly used for electromagnetic shielding, which can reduce the impact of electromagnetic interference on the cable 2 and improve the stability of signal transmission. On the outside of the shielding layer 6, the cable is provided with an outer sheath layer 7, which is usually made of wear-resistant and weather-resistant materials to provide additional mechanical protection and waterproof functions. Measuring grooves are evenly arranged on the outside of the outer sheath layer 7, and the spacing between the measuring grooves is set to 50 cm. These grooves are helpful to fix the cable 2 and facilitate installation. A stretching ring 8 is arranged at the front end of the outer sheath layer 7, and the cable 2 can be connected to other equipment or structures through the stretching ring 8. Stretching ring grooves are evenly arranged on the inner and outer sides of the stretching ring 8. The design of the stretching ring groove can make the stretching ring 8 have a certain elasticity when subjected to external force, thereby reducing stress concentration and the risk of damage to the cable 2.
