Description

Technical Field

[0001] The utility model belongs to the technical field of power cables, and particularly relates to a highly flexible and wear-resistant power cable. Background Art

[0002] A cable is usually a rope-like cable formed by stranding several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a center. The whole is covered with a highly insulating covering layer. The cable has the characteristics of conducting electricity inside and being insulated outside. There are power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single-strand or multi-strand wires and insulating layers, and are used to connect circuits, electrical appliances, etc.

[0003] The prior art discloses an anti-aging and water-resistant flexible power cable (application number 202121711538.5), which includes a power cable body. The power cable body includes a base layer, an insulating layer, an impact-resistant layer, a wrapping layer and a protective layer. One side of the surface of the base layer is fixedly connected to one side of the insulating layer, and one side of the insulating layer away from the base layer is fixedly connected to one side of the impact-resistant layer. One side of the impact-resistant layer away from the insulating layer is fixedly connected to one side of the wrapping layer. Through the cooperation of the power cable body, the base layer, the insulating layer, the impact-resistant layer, the wrapping layer, the protective layer, the anti-corrosion layer and the wear-resistant layer, the utility model achieves the purpose of good use effect.

[0004] The above prior art achieves the purpose of wear resistance and waterproofness through the cooperation of the base layer, the insulating layer, the impact-resistant layer, the wrapping layer, the protective layer, the anti-corrosion layer and the wear-resistant layer. However, there are certain defects in the flexibility, overall toughness and strength of the above prior art. The reason is that the cooperation of the impact-resistant layer and the wear-resistant layer set in the prior art may reduce the overall flexibility of the cable, making the cable become relatively hard. Although the strength is achieved, the flexibility is reduced.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0024] A highly flexible wear-resistant power cable, as shown in the figure, includes an outer protective layer 10. A waterproof coating is further provided on the outer wall of the outer protective layer 10. A wear-resistant layer 11 is fixedly provided on the inner wall of the outer protective layer 10. An anti-corrosion layer 12 is fixedly provided on the inner wall of the wear-resistant layer 11. A first filling layer 15 and a flexible component are provided in the cavity of the anti-corrosion layer 12. The first filling layer 15 is filled between the flexible component and the inner wall of the anti-corrosion layer 12. Multiple groups of flexible sheaths 20 are provided in the cavity of the flexible component. A conductor core 24 is provided in the flexible sheath 20.

[0025] As shown in the figure, the flexible component includes a rectangular flexible rubber layer 13. The flexible rubber layer 13 is provided at the central position of the anti-corrosion layer 12. Multiple groups of flexible rubber support plates 14 are fixedly provided on the outer wall of the flexible rubber layer 13. The other ends of the flexible rubber support plates 14 are fixedly provided together with the inner wall of the anti-corrosion layer 12. The first filling layer 15 is filled in the space formed by the flexible rubber layer 13, the flexible rubber support plates 14 and the anti-corrosion layer 12. The flexible sheath 20 is arc-shaped and is fixedly provided on the inner wall of the flexible rubber layer 13. A shielding filling layer 21 is filled in the cavity of the flexible sheath 20.

[0026] In this solution, through the provided outer protective layer 10, wear-resistant layer 11, and anti-corrosion layer 12, the outer protective layer 10 plays the most direct external protection role. The wear-resistant layer 11 improves the overall wear resistance of the cable in this solution. Even if the outer protective layer 10 is damaged by external force, the wear-resistant layer 11 can still protect the internal wire core 24, and the anti-corrosion layer 12 can play an anti-corrosion role.

[0027] Specifically, by arranging a flexible rubber layer 13, a flexible rubber support plate 14, and a first filling layer 15 in the cavity of the anti-corrosion layer 12, the cooperation of the flexible rubber layer 13 and the flexible rubber support plate 14 can play a role in protecting the internal wire core 24, and the flexible rubber layer 13 and the flexible rubber support plate 14 can improve the overall flexibility of the cable. The first filling layer 15 is filled in the cavity of the anti-corrosion layer 12, and the material of the first filling layer 15 can be nylon filler. This can not only improve the overall toughness and strength of the cable in this solution, but also improve the flexibility of the cable in this solution.

[0028] In this solution, the provided flexible sheath 20 separates each wire core 24, and can protect the wire core 24 individually. The second filling layer 16 is filled in the flexible rubber layer 13 and separates the flexible sheath 20. The material of the second filling layer 16 can be asbestos filler or flame-retardant cotton filler, which can play a certain flame-retardant effect and at the same time improve the overall flexibility of the power cable in this solution.
