Description

Technical Field

[0001] This utility model relates to the field of thin-walled locomotive cable technology, specifically a wear-resistant thin-walled locomotive cable. Background Technology

[0002] Thin-walled locomotive cables are wires and cables specifically designed for modern locomotives (including automobiles, motorcycles, rail transit, etc.). Their core feature is "thin walls"—that is, while ensuring electrical performance and mechanical strength, they achieve a lighter and more space-saving wiring solution by optimizing the thickness of insulation and sheath materials. They use high-performance insulation materials (such as cross-linked polyethylene XLPE, thin-walled PVC, etc.) to significantly reduce the outer diameter and reduce the weight of the wire harness while meeting the requirements for pressure resistance and temperature resistance, thus adapting to the wiring needs of the confined space of locomotives. However, the existing wear-resistant thin-walled locomotive cables still have certain defects. While traditional wear-resistant thin-walled locomotive cables can be used effectively, users often bend them during daily use. This bending can easily damage the cable's internal structure and protective layer. Furthermore, the transmission of a single cable is not stable, and the cable may become unusable when the outer sheath is damaged. The cable's low protective strength is a frequent source of frustration for users. Utility Model Content

[0003] The purpose of this invention is to provide a wear-resistant thin-walled locomotive cable to solve the problems mentioned in the background art, such as the fact that users often bend the cable during daily use, which can easily damage the cable's internal structure and protective layer. Furthermore, the transmission of a single cable is not stable, and the cable may become unusable when the outer sheath is damaged. The cable's protective strength is also low, which often troubles users.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant thin-walled locomotive cable, comprising a cable layer and a wear-resistant layer. The cable layer includes a first copper cable, a second copper cable, a first outer sheath, a second outer sheath, and an outer sheath protective layer. The first outer sheath is tightly fitted to the outer layer of the first copper cable, and the second outer sheath is tightly fitted to the outer layer of the second copper cable. The first copper cable and the first outer sheath are tightly wound with the second copper cable and the second outer sheath. An outer sheath protective layer is tightly fitted to the outer layers of the first outer sheath and the second outer sheath, and the outer surface of the outer sheath protective layer is coated with lubricating oil.

[0005] As a preferred technical solution of this utility model, the wear-resistant layer includes an inner protective layer, a middle protective layer, an outer protective layer, a repair layer, photosensitive repair microcapsules, and protective fins, with the inner protective layer tightly attached to the outside of the outer protective layer.

[0006] As a preferred embodiment of this utility model, a middle protective layer is provided outside the inner protective layer, and the middle protective layer is closely fitted to the inner protective layer.

[0007] As a preferred embodiment of this utility model, an outer protective layer is provided outside the middle protective layer, and the outer protective layer is closely fitted to the middle protective layer.

[0008] As a preferred embodiment of this utility model, a repair layer is provided on the outside of the outer protective layer, and the repair layer is tightly fitted to the outer protective layer.

[0009] As a preferred embodiment of this utility model, a protective fin is provided on the outside of the repair layer, the protective fin is fixedly installed on the outer surface of the repair layer, and photosensitive repair microcapsules are embedded on the surface of the repair layer.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This wear-resistant thin-walled locomotive cable has excellent wear resistance. The design of the protective fins greatly improves wear resistance, and the outer protective layer can resist high-frequency vibration environments. When the repair layer is damaged, the photosensitive repair microcapsules release repair agents, which can be quickly cured under ultraviolet irradiation, ensuring the strength of the repair layer. In addition, the protective fins can adapt to the bending angle, allowing the cable to be bent at will. Through multi-layer protection and repair layer repair, the cable has high strength, good protection performance, and is convenient for users. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 This utility model provides a technical solution: a wear-resistant thin-walled locomotive cable, comprising a cable layer 1 and a wear-resistant layer 2. The cable layer 1 includes a first copper cable 101, a second copper cable 102, a first outer sheath 103, a second outer sheath 104, and an outer sheath protective layer 105. The first outer sheath 103 is tightly attached to the outer layer of the first copper cable 101, and the second outer sheath 104 is tightly attached to the outer layer of the second copper cable 102. The first copper cable 101 and the first outer sheath 103 are tightly wound with the second copper cable 102 and the second outer sheath 104. The outer sheath protective layer 105 is tightly attached to the outer layer of the first outer sheath 103 and the second outer sheath 104, and the outer surface of the outer sheath protective layer 105 is coated with lubricating oil.

[0015] The wear-resistant layer 2 includes an inner protective layer 201, a middle protective layer 202, an outer protective layer 203, a repair layer 204, a photosensitive repair microcapsule 205, and a protective fin 206. The outer protective layer 105 is tightly fitted with the inner protective layer 201.

[0016] An inner protective layer 201 is provided with a middle protective layer 202 outside the inner protective layer 201, and the middle protective layer 202 is closely attached to the inner protective layer 201.

[0017] An outer protective layer 203 is provided outside the middle protective layer 202, and the outer protective layer 203 is tightly fitted to the middle protective layer 202.

[0018] A repair layer 204 is provided on the outside of the outer protective layer 203, and the repair layer 204 is tightly fitted to the outer protective layer 203.

[0019] The repair layer 204 is covered with a protective fin 206, which is fixedly installed on the outer surface of the repair layer 204. The surface of the repair layer 204 is inlaid with photosensitive repair microcapsules 205.

[0020] Working principle: When using a wear-resistant thin-walled locomotive cable, the first copper cable 101 and the second copper cable 102 adopt a tightly wound structure to reduce electromagnetic interference and improve signal transmission stability. The first outer sheath 103 and the second outer sheath 104 are made of highly elastic materials such as TPU to buffer mechanical stress. The outer sheath protective layer 105 is coated with lubricating oil to reduce the coefficient of friction with the outside. The wear-resistant layer 2 consists of an inner protective layer 201 as a basic buffer layer that absorbs vibration energy; a middle protective layer 202 made of aramid fiber that resists transverse shear force; an outer protective layer 203 made of modified PEEK or UHMWPE material that directly contacts external wear; a repair layer 204 with embedded photosensitive repair capsules 205 that release a repair agent after the sheath is damaged and quickly cure under ultraviolet light for rapid repair; and protective fins 206 with a biomimetic fin structure that dynamically disperses frictional stress. When bent, the protective fins 206 overlap to form a continuous protective surface. When the cable bends or vibrates, the protective fins 206 adjust their angle through micro-displacement to avoid localized concentrated wear, thus completing a series of tasks.
