The other end of the cable line 9 is provided with an output end joint 10.

[0025] Specifically, in the present utility model, an input end connector 13 is provided at one end of the cable. A hanging ring is provided at the bottom end of the input end connector 13. During use, the input end connector 13 is connected to the power supply connection point, and is hung on a hook near the power supply through the hanging ring, so that the connection between the input end connector 13 and the power supply connection point is firm, and it can effectively avoid the situation that the cable interface becomes loose and detached after the wire and cable are frequently moved, stretched, and twisted for a long time.

[0026] The cable 9 includes a tensile skin 1 provided on the outermost layer of the cable 9. An armor layer 2 is provided inside the tensile skin 1. A sheath layer 3 is provided on the inner wall of the armor layer 2. A cable cavity 4 is provided on the inner wall of the sheath layer 3. A plurality of battery cores 8 are provided in the cable cavity 4.

[0027] Among them, in the present utility model, structural devices such as a tensile skin 1, an armor layer 2, and a sheath layer 3 are provided inside the cable. The tensile skin 1 is a fiber braided layer, and the fiber braided layer is a form of its light protection layer. Its main function is to protect the insulation from being eroded by various light, heat, humidity, low temperature, acid-base gases and external forces, so as to ensure the stable operation of the cable. The fiber braided layer is a synthetic fiber, such as polyester, nylon, and aramid materials, which have high breaking strength and wear resistance, and improve the tensile performance of the wire outer skin. Aramid fibers or glass fibers and other reinforcing materials are also added to the fiber braided layer, which can significantly improve the tensile strength of the wire outer skin.

[0028] The armor layer 2 further improves the tensile, compressive, anti-torsion and other properties of the cable or wire. It can effectively prevent the connected cable from being distorted, knotted, abraded, and broken after being frequently moved, stretched, and twisted for a long time.

[0029] The armor layer 2 is an outer structure used to protect the cable or wire, usually made of metal or non-metal materials. The main function of the armor layer 2 is to provide additional mechanical protection to prevent the cable or wire from being affected by external factors (such as physical damage, chemical corrosion, biological invasion, etc.). In addition, the armor layer 2 can also improve the tensile, compressive, anti-torsion and other properties of the cable or wire, making it suitable for various harsh environments and special occasions.

[0030] The outer layer of each battery core 8 is wrapped with a battery core protective film 7. The outer layer of the battery core protective film 7 is wrapped with an insulating rubber layer 6. The outer wall of the insulating rubber layer 6 is wrapped with an insulating sleeve protective film 5. The battery core protective film 7 is made of polyethylene material. The cable cavity 4 is filled with a silicate material, specifically calcium silicate. The flame retardant filler 4 can avoid combustion, corrosion resistance and can provide a certain strength for the cable. It should be noted that in other specific embodiments, the above-mentioned flame retardant filler 4 can also be magnesium silicate or a mixture of magnesium silicate and calcium silicate. Embodiment 2

[0031] Please refer toFigures 1-3 , which is another technical solution provided by the present utility model. This embodiment has similarities with the above-mentioned Embodiment 1, and the similarities will not be elaborated in this embodiment. The specific differences are as follows:

[0032] A tensile power cable includes a cable line 9. One end of the cable line 9 is provided with an input end connector 13. A hanging ring 11 is rotatably connected to the bottom end of the input end connector 13. The other end of the cable line 9 is provided with an output end connector 10.

[0033] Specifically, the present utility model is provided with an input end connector 13 at one end of the cable line, and a hanging ring is provided at the bottom end of the input end connector 13. During use, by connecting the input end connector 13 to the power supply connection point and hanging it on a hook near the power supply through the hanging ring, the connection between the input end connector 13 and the power supply connection point is made firm, which can effectively avoid the situation that the cable interface is loosened and detached after the wire and cable move, stretch, and twist frequently for a long time.

[0034] The input end connector 13 includes a metal plug 12 provided at the top end of the input end connector 13, which is convenient for connecting with the power supply connector to conduct electricity. The input end connector 13 includes a power-on ring 14 provided on the surface of the input end connector 13. The power-on ring 14 is a light-emitting lamp ring. When the cable line 9 is working, the power-on ring 14 lights up, which is convenient for personnel to observe whether the connection between the cable line 9 and the power supply connector is firm and the power supply is normal. A second pulling ring 15 is also provided at the root of the output end connector 10. By hanging the second pulling ring 15 on a hook near the power supply interface of the lifting grab machine, the connection between the output end connector 10 and the power supply interface is made firm, which can effectively avoid the situation that the output end connector 10 and the power supply interface are loosened and detached after the wire and cable move, stretch, and twist frequently for a long time.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered by the scope of the claims of the present utility model.
