[0028] As a further implementation of this solution, the inner side of the TPO layer 51 is hollow, and the inner side of the TPO layer 51 is fixedly connected to the outer side of the tinned copper wire braided shield 4 to increase the cable's pulling resistance;

[0029] As a further implementation of the present solution, the number of the conical countersunk columns 53 is several, and the shape of the conical countersunk columns 53 is a conical countersunk body, which further improves the bending performance of the device;

[0030] As a further implementation of the present scheme, the shape of the conical countersunk groove 55 is opened in the conical countersunk body, and the conical countersunk groove 55 corresponds to the buffer wear-resistant block 54 one by one, thereby improving the stability of the connection between the TPO layer 51 and the cross-linked elastomer polyolefin sheath body 52;

[0032] Workflow: The aluminum alloy soft conductor 1 adopts a six-series aluminum alloy rod material, and adopts a multi-head aluminum alloy wire drawing machine to draw an aluminum alloy monofilament with a diameter of 0.30-0.50mm. A newly designed continuous drawing and annealing annealing process is used to ensure that the tensile strength, elongation at break, and DC resistivity of the aluminum alloy monofilament after annealing remain stable, so as to improve the defects of excessive deviation of mechanical and electrical properties caused by uneven heat transfer caused by annealing in an aging furnace in the traditional process, so that the product has stable electrical and mechanical properties and easy bending characteristics. The cross-linked elastomer polyolefin insulation 2 adopts irradiated cross-linked polyolefin as the cable insulation layer, and adopts a special extrusion process.

The tinned copper wire has the characteristics of anti-oxidation and corrosion resistance. After the cable is insulated, the aluminum-plastic composite tape is wrapped and a shielding protection layer is woven on the surface of the aluminum-plastic tape, which can greatly improve the cable's anti-interference ability and increase the cable's anti-pulling ability. The TPO layer 51 is soft TPO, and the buffer wear-resistant block 54 is used to provide the necessary flexibility and wear resistance. An irradiated cross-linked polyolefin elastomer material is used as the cable outer sheath, which has the advantages of good cable bending performance, resistance to long-term sunlight aging, resistance to battery acid, good mechanical properties, and no pollution to the environment. The conical countersunk column 53 is installed inside the conical countersunk groove 55 to further improve the bending performance of the device, while improving the stability of the connection between the TPO layer 51 and the cross-linked elastomer polyolefin sheath body 52. ​​The buffer wear-resistant block 54 can provide a certain wear buffer space for the device.
