Description

Technical Field

[0001] This utility model relates to the field of electrical wires, specifically to a wear-resistant electrical wire with a multi-layer protective structure. Background Technology

[0002] As a fundamental component for power transmission and signal transmission, electrical wires are widely used in numerous fields such as industry, construction, and transportation. With the development of modern technology, the performance requirements for electrical wires are becoming increasingly stringent, especially in complex and harsh environments, such as scenarios with frequent mechanical vibration, high friction coefficients, and numerous impact loads. In these cases, the wear resistance and protective capabilities of electrical wires have become key indicators.

[0003] Traditional abrasion-resistant wires typically employ single-layer or multi-layer protective structures, such as directly wrapping a layer of hard abrasion-resistant material or a flexible protective layer around the core. However, these structures have certain limitations. While a single-layer hard abrasion-resistant layer can resist external abrasion to some extent, it lacks elasticity and is prone to cracking when subjected to bending, stretching, or impact, potentially exposing the internal core and posing a safety hazard. On the other hand, a simple flexible protective layer, although possessing good flexibility and impact resistance, has poor abrasion resistance and is easily worn down over long-term use, affecting the wire's lifespan.

[0004] To address these issues, some existing technologies employ a multi-layered composite structure, where an elastic layer and an abrasion-resistant layer are sequentially wrapped around the outer surface of the wire core. While this structure improves the wire's abrasion resistance and impact resistance to some extent, it still has some shortcomings. For example, the bonding strength between the elastic and abrasion-resistant layers is limited, making delamination prone to occur during long-term use, leading to a decrease in protective effectiveness. Furthermore, this structure provides relatively uniform protection against impacts and abrasion from different directions, lacking specific design for areas of the wire prone to wear in actual use, resulting in weak targeted protection.

[0005] Furthermore, the existing protective structures of electrical wires often lack effective buffering mechanisms when facing complex environments. When the wire is subjected to external impact, the impact force can be directly transmitted to the battery core, potentially damaging it and affecting the normal use of the wire. Moreover, in scenarios requiring frequent movement or bending, the protective structures of existing electrical wires are prone to fatigue damage, further reducing the wire's lifespan and reliability. Utility Model Content

[0006] The purpose of this invention is to address the above-mentioned deficiencies and provide a wear-resistant wire with a multi-layer protective structure. The wire has an elastic memory layer, corrugated reinforcing ribs, segmented wear-resistant sleeves, and a suspended protective strip arranged sequentially on the outside of the core. The suspended protective strip is connected to the segmented wear-resistant sleeves by elastic connecting ribs. This invention solves the technical problems of existing wires, such as single protective performance, weak impact resistance, and difficulty in balancing wear resistance and flexibility.

[0007] The objective of this utility model is achieved through the following means:

[0008] A wear-resistant wire with a multi-layer protective structure includes a core body, an elastic memory layer wrapped around the core body, corrugated reinforcing ribs wrapped around the elastic memory layer, and segmented wear-resistant sleeves wrapped around the corrugated reinforcing ribs. The segmented wear-resistant sleeves include a hard wear-resistant sleeve and a flexible wear-resistant sleeve, which are alternately distributed outside the corrugated reinforcing ribs. A suspended protective strip is provided outside the segmented wear-resistant sleeve. Elastic connecting ribs evenly distributed along a ring are installed between the suspended protective strip and the segmented wear-resistant sleeve, and the two ends of the elastic connecting ribs are fixedly connected to the segmented wear-resistant sleeve and the suspended protective strip, respectively.

[0009] Furthermore, the corrugated reinforcing ribs are fixedly connected to the elastic memory layer, and the segmented wear-resistant sleeves are fixedly connected to the corrugated reinforcing ribs.

[0010] Furthermore, the segmented wear-resistant sleeve is provided with anti-slip ridges on its exterior, and the anti-slip ridges are integrally formed with the hard wear-resistant sleeve and the flexible wear-resistant sleeve, thereby improving the anti-slip performance of the segmented wear-resistant sleeve.

[0011] Furthermore, the outer side of the suspended protective belt is provided with flexible protrusions evenly distributed along the ring, and the flexible protrusions are fixedly connected to the suspended protective belt. The flexible protrusions are made of soft but tough material, which can prevent birds from pecking at them and will not cause harm to people or other objects.

[0012] Furthermore, the outer side of the suspended protective belt is provided with hemispherical anti-impact protrusions evenly distributed along the ring on both sides of the flexible protrusions, and the hemispherical anti-impact protrusions are fixedly connected to the suspended protective belt. The hemispherical anti-impact protrusions can prevent local stress concentration.

[0013] Furthermore, ceramic microparticles are embedded at the rib peaks of the corrugated reinforcing ribs. The ceramic microparticles are spherical with a particle size of 0.1 mm. The ceramic microparticles have the characteristics of high hardness and high wear resistance, thereby enhancing the wear resistance of key parts.

[0014] The beneficial effects of this utility model are:

[0015] This invention achieves multi-layer protection for the wire by sequentially setting an elastic memory layer, corrugated reinforcing ribs, segmented wear-resistant sleeves, and a suspended protective strip on the outside of the battery cell, and installing elastic connecting ribs between the suspended protective strips and the segmented wear-resistant sleeves. This provides significant protection and wear resistance. The elastic memory layer can quickly return to its original shape after the wire is deformed by external force, effectively protecting the internal battery cell. The corrugated reinforcing ribs not only enhance the structural strength of the wire but also disperse external pressure and reduce localized wear.

[0016] The alternating distribution of hard and flexible wear-resistant sleeves in the segmented wear-resistant sleeve ensures that the wire maintains good wear resistance and flexibility under different conditions, solving the problem of balancing wear resistance and flexibility in traditional protective structures. The suspended protective strip is connected to the segmented wear-resistant sleeve through elastic connecting ribs, forming a buffer space that can effectively absorb and disperse external impact forces, preventing the impact force from being directly transmitted to the core, thus improving the wire's impact resistance. This multi-layered protective structure solves the problems of single protective performance, weak impact resistance, and difficulty in balancing wear resistance and flexibility in existing technologies, improving the service life and reliability of wires in complex and harsh environments.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. This embodiment refers to... Figures 1-4The present invention relates to a wear-resistant wire with a multi-layer protective structure, comprising a core body 1, an elastic memory layer 2 wrapped around the core body 1, corrugated reinforcing ribs 3 wrapped around the elastic memory layer 2, and segmented wear-resistant sleeves wrapped around the corrugated reinforcing ribs 3. The segmented wear-resistant sleeves include a hard wear-resistant sleeve 4 and a flexible wear-resistant sleeve 5, which are alternately distributed outside the corrugated reinforcing ribs 3. A suspended protective strip 7 is provided outside the segmented wear-resistant sleeves. Elastic connecting ribs 8, which are evenly distributed along a ring, are installed between the suspended protective strip 7 and the segmented wear-resistant sleeves. The two ends of the elastic connecting ribs 8 are fixedly connected to the segmented wear-resistant sleeves and the suspended protective strip 7, respectively.

[0023] like Figure 1 and Figure 4 As shown, the corrugated reinforcing rib 3 is fixedly connected to the elastic memory layer 2, and the segmented wear-resistant sleeve is fixedly connected to the corrugated reinforcing rib 3.

[0024] like Figure 1 and Figure 3 As shown, the segmented wear-resistant sleeve has anti-slip ridges 6 on its outer surface, and the anti-slip ridges 6 are integrally formed with the hard wear-resistant sleeve 4 and the flexible wear-resistant sleeve 5. The anti-slip ridges 6 improve the anti-slip performance of the segmented wear-resistant sleeve.

[0025] like Figure 1 and Figure 2 As shown, the outside of the suspended protective belt 7 is provided with flexible protrusions 10 evenly distributed along the ring, and the flexible protrusions 10 are fixedly connected to the suspended protective belt 7. The flexible protrusions 10 are made of soft but tough material, which can prevent birds from pecking at them and will not cause harm to people or other objects.

[0026] like Figure 1 and Figure 2 As shown, the outer side of the suspended protective belt 7 is provided with hemispherical anti-impact protrusions 9 evenly distributed along the ring on both sides of the flexible protrusions 10. The hemispherical anti-impact protrusions 9 are fixedly connected to the suspended protective belt 7. The hemispherical anti-impact protrusions 9 can prevent local stress concentration. When subjected to external impact, the hemispherical anti-impact protrusions 9 can evenly distribute the impact force to the surrounding area, avoiding the protective belt from breaking or the internal structure from being damaged due to excessive local stress.

[0027] like Figure 1 and Figure 4 As shown, ceramic microparticles are embedded at the rib peaks of the corrugated reinforcing rib 3. The ceramic microparticles are spherical with a particle size of 0.1 mm. The ceramic microparticles have the characteristics of high hardness and high wear resistance, and enhance the wear resistance of key parts through ceramic microparticles.

[0028] The winding process of a wear-resistant wire with a multi-layer protective structure in this embodiment is as follows: The wear-resistant wire takes the core 1 as the core, and the elastic memory layer 2 wrapped on the outside provides basic elastic protection. The corrugated reinforcing ribs 3 outside the elastic memory layer 2 enhance the wear resistance of key parts through ceramic particles at the rib peaks. They are fixedly connected to the elastic memory layer 2, and at the same time provide support and fixed connection for the external segmented wear-resistant sleeve (hard wear-resistant sleeve 4 and flexible wear-resistant sleeve 5 are distributed alternately). The alternating structure takes into account both wear resistance and flexibility. The anti-slip texture 6 on the outside of the segmented wear-resistant sleeve improves the anti-slip performance. The outside of it is connected to the suspended protective strip 7 through the elastic connecting rib 8. The elastic connecting rib 8 can buffer the external impact force. The flexible protrusions 10 on the outside of the suspended protective strip 7 prevent birds from pecking. The hemispherical anti-impact protrusions 9 on both sides disperse the impact stress. The whole achieves wear resistance, impact resistance, and anti-pecking protection functions through the synergistic effect of the multi-layer structure.

[0029] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
