Description

Technical Field

[0001] This utility model relates to cables, specifically to a cable that is rodent-proof, termite-proof, and tensile-resistant. Background Technology

[0002] Cables are widely used in power and signal transmission. However, in areas with high rates of rodents and ants, cable use often faces numerous problems. On the one hand, rodents and ants easily gnaw and damage cables, causing insulation damage and leading to safety hazards such as leakage and short circuits, affecting the normal transmission of power or signals. On the other hand, during the laying, installation, and use of cables, the structure of ordinary cables is easily damaged by external forces, reducing their lifespan and even causing transmission interruptions.

[0003] Existing cables are insufficient in terms of rodent and termite resistance and tensile strength, making it difficult to meet the needs of use in complex environments. Therefore, there is an urgent need to design a cable with rodent and termite resistance and tensile strength. Utility Model Content

[0004] The purpose of this invention is to provide a cable that is resistant to rodents and ants and has tensile strength, in order to solve the problems of existing cables being easily damaged by rodents and ants and having insufficient tensile strength, thereby improving the safety and service life of the cable.

[0005] To solve the above-mentioned technical problems, this utility model provides a cable with rodent and ant resistant and tensile strength, comprising:

[0006] The first insulating layer has a circular cross-section;

[0007] The multi-strand wire is distributed inside the first insulation layer. Each wire includes a second insulation layer with a circular cross-section and multiple metal wires tightly wrapped in the second insulation layer. The multiple metal wires are twisted together to form a spiral structure.

[0008] Flame-retardant filler is used to fill the gap between the multi-strand wires and the first insulation layer;

[0009] A rodent-proof layer, covering the outside of the first insulating layer, has an agent layer coated on the outer skin of the first insulating layer and a mesh metal wire layer disposed outside the agent layer;

[0010] A tensile layer is provided to cover the rodent-proof layer.

[0011] An outer sheath layer covers the tensile layer.

[0012] Furthermore, the first insulating layer is a PVC insulating layer.

[0013] Furthermore, the flame-retardant filler is flame-retardant glass fiber cotton.

[0014] Furthermore, the pharmaceutical layer is a layer of pungent natural plant essential oils.

[0015] Furthermore, the natural plant essential oil layer includes one or more mixtures of peppermint oil layer and lavender oil layer.

[0016] Furthermore, the mesh metal wire layer is a stainless steel wire mesh structure layer.

[0017] Furthermore, the tensile layer is a woven structure layer made of multiple high-strength aramid fiber filaments.

[0018] Furthermore, the outer sheath layer is a neoprene rubber layer.

[0019] Furthermore, a buffer layer is provided between the rodent-proof layer and the tensile layer.

[0020] Furthermore, the buffer layer is a foamed silicone layer.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model cable has a significant rodent and ant prevention effect: by setting up a rodent and ant prevention layer composed of an agent layer and a mesh metal wire layer, the agent layer uses the repellent effect of natural plant essential oils to prevent rodents and ants from approaching the cable at the source, and the mesh metal wire layer, with its high strength and hardness, further blocks rodents and ants from gnawing. The double protection greatly improves the rodent and ant prevention ability of the cable, effectively avoids cable damage caused by rodents and ants gnawing, and ensures the normal transmission of power and signals.

[0023] 2. The cable of this utility model has excellent tensile strength: the tensile layer is woven from high-strength aramid fiber filaments, which can withstand greater tensile force, and the buffer layer can absorb external force and reduce the impact of external force on the internal structure. This allows the cable to maintain structural integrity even when subjected to greater external force during laying, installation and use, thus extending the service life of the cable.

[0024] 3. The cable of this utility model has good comprehensive performance: the insulation layer ensures the insulation performance of the cable, the outer sheath layer has good wear resistance, aging resistance and corrosion resistance, the flame retardant filler improves the flame retardant performance of the cable, and the structure of each layer works together to give the cable good comprehensive performance such as insulation, flame retardancy, wear resistance and aging resistance, and can adapt to complex use environments.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1: The specific structure of this utility model is as follows:

[0032] Please refer to the appendix. Figure 1-2 The present invention provides a rodent-proof and tensile-resistant cable, comprising a first insulation layer 4, multi-strand conductors, flame-retardant filler 3, rodent-proof layer, tensile-resistant layer 7, and outer sheath layer 8.

[0033] The first insulating layer 4 has a circular cross-section and is a PVC insulating layer. PVC insulating layer is made of polyvinyl chloride material and has good insulation properties, which can effectively prevent current leakage and signal interference.

[0034] The multi-strand conductors are distributed inside the first insulating layer 4. Each conductor includes a second insulating layer 2 with a circular cross-section and multiple metal conductors 1 tightly wrapped within the second insulating layer 2. The multiple metal conductors are twisted together to form a spiral structure. The second insulating layer 2 is made of polyvinyl chloride and has good insulation properties, effectively preventing current leakage and signal interference. The multi-strand conductors are used to transmit power or signals, and the multi-strand twisted structure of the multiple metal conductors 1 improves the conductor's flexibility and conductivity.

[0035] Flame-retardant filler 3 fills the gap between the multi-strand conductors and the first insulation layer 4; the flame-retardant filler 3 is flame-retardant glass fiber cotton. The filling layer formed by the flame-retardant filler 3 can fill the gap between the multi-strand conductors and the insulation layer, making the cable structure more compact. At the same time, the flame-retardant material can improve the flame-retardant performance of the cable and enhance the safety of the cable.

[0036] A rodent-repellent layer covers the outside of the first insulation layer 4 and includes an agent layer 5 coated on the outer surface of the first insulation layer 4 and a mesh wire layer 6 disposed outside the agent layer 5. The agent layer 5 is a layer of pungent natural plant essential oils. The natural plant essential oil layer includes one or more mixtures of peppermint oil and lavender oil. The mesh wire layer 6 is a stainless steel wire mesh structure layer. Specifically, the agent layer is formed by uniformly applying a repellent containing natural plant essential oils (such as peppermint oil and lavender oil) to the surface of the insulation layer. The natural plant essential oils have a repellent effect on rodents and ants, effectively preventing them from approaching the cable. The mesh wire layer is made of stainless steel wire mesh, tightly wrapped around the outside of the agent layer. The stainless steel wire mesh has high strength and hardness, further preventing rodents and ants from gnawing on it, making it difficult for them to break through the mesh wire layer.

[0037] Tensile layer 7 covers the rodent-proof layer; tensile layer 7 is a braided structure layer woven from multiple high-strength aramid fiber filaments. Aramid fiber filaments have high strength and high modulus, and can withstand greater tensile force, effectively improving the tensile performance of the cable. Furthermore, the braided structure of the aramid fiber filaments reduces the weight of the cable while ensuring tensile performance.

[0038] The outer sheath layer 8 covers the tensile layer 7. The outer sheath layer 8 is a neoprene rubber layer. The outer sheath layer 8 wraps around the outside of the tensile layer and is made of neoprene rubber. Neoprene rubber has good wear resistance, aging resistance and corrosion resistance, which can protect the internal structure and extend the service life of the cable.

[0039] Example 2:

[0040] like Figure 2-3 As shown, Figure 3 This is a cross-sectional view of the second type of cable structure of this utility model.

[0041] Figure 3 Is Figure 1A buffer layer 9 is added to the existing structure. Specifically, a buffer layer 9 is provided between the rodent-proof layer and the tensile layer 7. The buffer layer 9 is a foamed silicone layer. Foamed silicone material has good elasticity and cushioning properties. When the cable is subjected to external force pulling or compression, the buffer layer can absorb part of the external force, reducing the direct effect of the external force on the rodent-proof layer and the tensile layer, further improving the tensile strength and structural stability of the cable. When this cable is used in complex construction environments, it can work normally regardless of whether it is subjected to external force pulling or rodent interference, demonstrating good comprehensive performance.

[0042] In summary, this utility model of cable exhibits significant rodent and ant prevention effects: by setting up an anti-rodent and ant layer composed of an agent layer and a mesh metal wire layer, the agent layer utilizes the repellent effect of natural plant essential oils to prevent rodents and ants from approaching the cable at the source, while the mesh metal wire layer, with its high strength and hardness, further blocks rodents and ants from gnawing. This dual protection greatly improves the cable's rodent and ant prevention capabilities, effectively avoiding cable damage caused by rodents and ants gnawing, and ensuring the normal transmission of power and signals.

[0043] This utility model cable has excellent tensile strength: the tensile layer is woven from high-strength aramid fiber filaments, which can withstand large tensile forces, and the buffer layer can absorb external forces and reduce the impact of external forces on the internal structure. This allows the cable to maintain its structural integrity even when subjected to large external forces during laying, installation and use, thus extending the service life of the cable.

[0044] This utility model cable exhibits excellent overall performance: the insulation layer ensures the cable's insulation performance, the outer sheath layer possesses good wear resistance, aging resistance, and corrosion resistance, and the flame-retardant filler improves the cable's flame-retardant properties. The coordinated structure of each layer gives the cable excellent comprehensive performance in terms of insulation, flame retardancy, wear resistance, and aging resistance, enabling it to adapt to complex operating environments. In actual use, when this cable was laid in an environment prone to rodent and ant infestation, after a period of observation, no signs of rodent or ant damage were observed. Furthermore, under a certain tensile force, the cable structure remained intact, and its performance remained stable.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
