[0030] Please refer to Figures 1 to 3 , this application provides a charging pile cable, including an outer sheath 10, a fixing frame 30 and a cable core 20. An accommodation cavity is defined inside the outer sheath 10; the fixing frame 30 is accommodated in the accommodation cavity and extends from one end of the outer sheath 10 to the other end. Among them, the fixing frame 30 includes a shaft body 31 and a plurality of partition plates 32 sequentially distributed along the axial direction of the shaft body 31. One side of the partition plate 32 close to the shaft body 31 is connected to the shaft body 31, and the side of the partition plate 32 away from the shaft body 31 abuts against the inner wall of the outer sheath 10, and a relatively independent placement space is defined between adjacent partition plates 32; the cable core 20 is installed in the installation space, and the surface of the cable core 20 abuts against the surface of the partition plate 32.

[0031] Based on the charging pile cable with the above technical features, by arranging the fixing frame 30 in the accommodation cavity of the outer sheath 10, and the fixing frame 30 is composed of the shaft body 31 and a plurality of partition plates 32, and using the plurality of partition plates 32 distributed along the axial direction of the shaft body 31, so that a relatively independent placement space can be formed between adjacent partition plates 32, and then different cable cores 20 are placed into different placement spaces, reducing the interference between cable cores 20 for different uses. At the same time, the surface of the cable core 20 abuts against the partition plate 32 and the inner surface of the outer sheath 10, ensuring that the cable core 20 is firmly installed in the placement space and preventing the cable core 20 from moving relatively and causing wear, which is beneficial to extending the service life of the charging pile cable.

[0032] In a possible implementation manner, elastic strips 40 extending in opposite directions are respectively arranged along both sides of the side of the partition plate 32 away from the shaft body 31; wherein, the outer diameter of the shaft core is greater than the distance between the elastic strips 40 of adjacent partition plates 32.

[0033] Exemplarily, since elastic strips 40 extending in opposite directions are respectively arranged along both sides of the side of the partition plate 32 away from the shaft body 31, so that an insertion opening is formed between the two elastic strips 40. When the cable core 20 is placed into the placement space, the cable core 20 is extruded from the placement space, so that the cable core 20 pushes open the elastic strips 40 until the cable core 20 is placed into the placement space. Then, the elastic strips 40 return to their original positions under their own elastic force. At this time, the elastic strips 40 will restrict the cable core 20 to ensure that the cable core 20 is firmly fixed in the placement space, avoiding movement and friction during use, resulting in wear of the cable core 20 or the outer sheath 10, which is beneficial to extending the service life of the charging pile cable.

[0034] In a possible implementation manner, the elastic strip 40 is arc-shaped and columnar. In this way, the cable core 20 can be better limited, avoiding the cable core 20 from shaking and causing wear during use.

[0035] In a possible implementation, it further includes a heat-conducting layer located between the outer sleeve 10 and the fixing frame 30, and the inner side surface of the heat-conducting layer is in contact with the partition plate 32 and the elastic strip 40; wherein, both the partition plate 32 and the elastic strip 40 are made of heat-conducting materials.

[0036] Exemplarily, by arranging a heat-conducting layer between the outer sleeve 10 and the fixing frame 30, and making the partition plate 32 and the elastic strip 40 in contact with the inner side surface of the heat-conducting layer, since the outer surface of the cable core 20 is in contact with the partition plate 32 and the elastic strip 40, so that the heat generated during the operation of the cable core 20 can be transferred to the heat-conducting layer, and finally the heat-conducting layer conducts out the heat, which can promote the heat dissipation of the cable core 20 to a certain extent and inhibit the high temperature of the cable core 20.

[0037] In a possible implementation, it further includes a waterproof layer 50, an armor layer 60, and a fiber braided layer 70 arranged in sequence from the inside to the outside, and a non-hygroscopic low-smoke and halogen-free flame retardant material is filled between the waterproof layer 50 and the heat-conducting layer.

[0038] It should be noted that the setting of the waterproof layer 50 can play a water-blocking effect, so that after the outer sleeve 10 is damaged by materials or gnawed by insects and rodents, the waterproof layer 50 can play a water-blocking effect and avoid the occurrence of electric leakage accidents caused by the damage of the outer sleeve 10. The setting of the armor layer 60 can enhance the electromagnetic interference resistance of the cable core 20, and can also resist external mechanical pressure, prevent the cable from being damaged by insects and rodents outdoors, improve the protection of the cable core 20, and extend its service life. The setting of the fiber braided layer 70 can prevent the outer sleeve 10 from falling off after mechanical damage or aging, and at the same time has the function of flame retardancy.

[0039] In a possible implementation, the armor layer 60 is a hot-dip galvanized steel wire braided armor. It should be noted that the armor layer 60 is made of hot-dip galvanized steel wire braided, so that it can not only enhance the electromagnetic interference resistance of the cable core 20, but also resist external mechanical pressure, improve the protection of the cable core 20, prevent the cable from being damaged by insects and rodents outdoors, and extend its service life.

[0040] In a possible implementation, the fiber braided layer 70 is made of glass fiber or carbon fiber braided. Exemplarily, the fiber braided layer 70 is made of glass fiber or carbon fiber braided, which can not only prevent the outer sleeve 10 from falling off after mechanical damage or aging, but also has the function of flame retardancy.

[0041] In a possible implementation, the cable core 20 includes a conductor 21, a mica tape 22, and an insulating layer 23. The mica tape 22 is wrapped around the outside of the conductor 21, and the insulating layer 23 is extruded around the outside of the mica tape 22.

[0042] It can be understood that the above embodiments only represent the preferred embodiments of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present utility model shall fall within the scope covered by the claims of the present utility model.
