Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, specifically to wires and cables with wear-resistant and pressure-resistant structures. Background Technology

[0002] With the continuous development of society, electric wires and cables are usually rope-like cables made of several or several groups of conductors, each group having at least two conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central point. Cables have the characteristics of being internally energized and externally insulated. In addition to the internal conductors, the outer layer of existing cables is almost entirely made of rubber and plastic materials. Although they have a certain degree of elasticity, they do not have good compressive strength. When a large pressure is applied to a local area, the outer layer is easily indented, and may even cause the internal conductors to break.

[0003] CN223471430U discloses a wear-resistant cable, "including a protective shell and an internal battery core, a connecting layer disposed on the surface of the protective shell, a protective layer disposed on the surface of the connecting layer, a reinforcing frame embedded inside the protective layer, and a braided layer disposed on the surface of the protective layer." This invention, through the design of wear blocks and reinforcing rods, prevents the protective layer from easily being damaged when the cable is subjected to friction, effectively improving the cable's wear resistance. However, the internal conductors are not separated, and under strong pressure, conductor breakage may still occur. In this case, signal interference may occur within the cable's internal conductors, affecting the cable's signal transmission.

[0004] Based on this, wires and cables with wear-resistant and pressure-resistant structures are now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide wires and cables with wear-resistant and pressure-resistant structures to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The wire and cable with a wear-resistant and pressure-resistant structure includes an outer protective layer, and the outer protective layer is provided with a separator component inside; The separating component includes a separating frame, which is cylindrical and has several placement slots on its outer perimeter. Each placement slot has an inner protective layer inside, and each inner protective layer has a wire wrapped inside. The separating component has a reinforcing component on its outer side. The reinforcing component includes an elastomer buffer layer disposed on the outside of the dividing frame, a pressure-bearing skeleton disposed on the outside of the elastomer buffer layer, a flame-retardant filling layer disposed on the outside of the pressure-bearing skeleton, and the flame-retardant filling layer disposed on the inside of the outer protective layer.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: a plurality of reinforcing columns are arranged in a horizontal array on the outer side of the outer protective layer, and a plurality of connecting rods are arranged in a vertical array on the outer side of the outer protective layer, each of the connecting rods being fixedly connected to all the reinforcing columns, and the reinforcing columns being galvanized steel wire.

[0008] In one alternative: the outer protective layer is made of ultra-high molecular weight polyethylene, and an insulating layer is provided between the outer protective layer and the flame-retardant filler layer, the insulating layer being made of cross-linked polyethylene.

[0009] In one alternative: the flame-retardant filler layer is made of ceramicized silicone rubber.

[0010] In one alternative, the pressure-bearing frame is made of high-strength engineering plastic.

[0011] In one alternative: the elastomeric buffer layer is made of thermoplastic polyurethane.

[0012] In one alternative: the divider is made of polypropylene.

[0013] In one alternative: the inner protective layer is made of halogen-free flame-retardant polyolefin.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention effectively isolates and fixes multiple conductors in independent placement slots through a segmented frame structure, thereby avoiding the breakage and signal interference problems caused by the conductors squeezing each other under high pressure, which is common in traditional cables, ensuring the stability of power and signal transmission. The reinforcing component forms a rigid-flexible protective system through an outer pressure-bearing skeleton and an inner elastic buffer layer. The pressure-bearing skeleton, made of high-strength engineering plastic, effectively resists and disperses external pressure, while the outermost layer, made of ultra-high molecular weight polyethylene, provides extreme wear resistance, effectively extending the cable's service life in complex environments. The mesh structure composed of longitudinal reinforcing columns and transverse connecting rods further enhances the cable's tensile strength and overall structural stability, preventing deformation during use. It also effectively improves the cable's fire safety performance, thereby further enhancing the cable's wear and pressure resistance. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-4 As shown, the wire and cable with a wear-resistant and pressure-resistant structure includes an outer protective layer 1, and a partition component is provided inside the outer protective layer 1; The separating component includes a separating frame 5, which is cylindrical and has several placement slots 8 around its outer perimeter. Each placement slot 8 has an inner protective layer 9 inside, and each inner protective layer 9 has a wire 10 wrapped inside. The separating component has a reinforcing component on its outer side. The reinforcing component includes an elastomer buffer layer 4, which is disposed on the outside of the dividing frame 5. A pressure-bearing skeleton 3 is disposed on the outside of the elastomer buffer layer 4, and a flame-retardant filling layer 2 is disposed on the outside of the pressure-bearing skeleton 3. The flame-retardant filling layer 2 is disposed on the inside of the outer protective layer 1. In this embodiment, the outer protective layer 1 serves as the outermost layer of protection, directly resisting external friction and corrosion. The splitting frame 5 is located at the center of the cable, and its cylindrical structure maintains the roundness of the cable. The placement grooves 8 opened around the perimeter provide independent and stable housing space for the inner protective layer 9 and the conductor 10. The flame-retardant filling layer 2 fills the periphery of the splitting frame 5, playing a role in flame retardancy and auxiliary fixation. The pressure-bearing skeleton 3 is set outside the flame-retardant filling layer 2, forming a rigid protective layer to resist external pressure. The elastic buffer layer 4 is located between the pressure-bearing skeleton 3 and the splitting frame 5, absorbing impact energy through elastic deformation.

[0022] In one embodiment, such as Figure 2As shown, a number of reinforcing columns 6 are arranged in a horizontal array on the outer side of the outer protective layer 1, and a number of connecting rods 7 are arranged in a vertical array on the outer side of the outer protective layer 1. Each connecting rod 7 is fixedly connected to all the reinforcing columns 6. The reinforcing columns 6 are made of galvanized steel wire and are arranged in a horizontal array inside the outer protective layer 1 to provide the main tensile strength. The connecting rods 7 are arranged in a vertical array and are fixedly connected to all the reinforcing columns 6 to form a stable spatial mesh structure. This mesh structure can not only effectively enhance the tensile performance of the cable, but also prevent the cable from undergoing excessive deformation during use, thereby improving the overall mechanical strength.

[0023] In one embodiment, such as Figure 2 As shown, the outer protective layer 1 is made of ultra-high molecular weight polyethylene. An insulating layer is provided between the outer protective layer 1 and the flame-retardant filling layer 2. The insulating layer is made of cross-linked polyethylene. The outer protective layer 1 is made of ultra-high molecular weight polyethylene, which can effectively resist long-term frictional wear. The insulating layer between the outer protective layer 1 and the flame-retardant filling layer 2 is made of cross-linked polyethylene, which has excellent electrical insulation and heat resistance properties, can withstand high operating temperatures, and ensures safe current transmission.

[0024] In one embodiment, such as Figure 2 As shown, the flame-retardant filler layer 2 is made of ceramicized silicone rubber. The flame-retardant filler layer 2 is made of ceramicized silicone rubber, which has good elasticity and sealing properties at room temperature. When it is exposed to high-temperature flames, it can gradually become ceramicized to form a hard heat insulation protective layer, effectively preventing the flame from spreading and the heat from being transferred, thus providing excellent fire protection for the cable.

[0025] In one embodiment, such as Figure 2 As shown, the pressure-bearing frame 3 is made of high-strength engineering plastics, such as PBT or nylon. These materials have high mechanical strength and rigidity, which can effectively withstand radial pressure from the outside and disperse and transmit concentrated pressure, preventing pressure from acting directly on the internal conductors and protecting the conductors from damage.

[0026] In one embodiment, such as Figure 2 As shown, the elastomer buffer layer 4 is made of thermoplastic polyurethane. The elastomer buffer layer 4 is made of thermoplastic polyurethane, which has excellent elasticity, toughness and resilience. When the cable is subjected to impact or local compression, it can absorb and buffer energy through its own elastic deformation to avoid instantaneous damage to the internal structure.

[0027] In one embodiment, such as Figure 2As shown, the dividing frame 5 is made of polypropylene. Polypropylene has good comprehensive properties, including sufficient rigidity to maintain the structural shape, while also having a certain degree of toughness. It has low cost and good electrical insulation properties, making it suitable as a conductor support structure.

[0028] In one embodiment, such as Figure 4 As shown, the inner protective layer 9 is made of halogen-free flame-retardant polyolefin. The inner protective layer 9 is made of halogen-free flame-retardant polyolefin. This material maintains good insulation performance while having flame-retardant properties. It does not produce toxic halogen gases when burning, making it more environmentally friendly and safe. It provides the most direct insulation protection and primary flame-retardant protection for the conductor.

[0029] The above embodiments disclose wires and cables with wear-resistant and pressure-resistant structures. Multiple conductors 10 are each wrapped with their respective inner protective layers 9 and securely placed in the placement slots 8 of the dividing frame 5, forming isolated independent units. This effectively prevents compression and signal interference between conductors. The dividing frame 5 is surrounded by an elastomer buffer layer 4, a pressure-bearing frame 3, and a flame-retardant filling layer 2. The elastomer buffer layer 4 absorbs external impact energy, the pressure-bearing frame 3 resists and disperses continuous pressure, the flame-retardant filling layer 2 provides fire protection, and the outermost protective layer 1 uses ultra-high temperature and pressure resistance. Made of polyethylene, it offers exceptional abrasion resistance. The longitudinal reinforcing columns 6 and the transverse connecting rods 7 form a reinforcing grid inside the outer protective layer, significantly improving the cable's tensile strength. When the cable is subjected to external pressure, this multi-layered structure effectively disperses and absorbs the pressure through the synergistic effect of rigid support and elastic buffering. When subjected to friction, the ultra-abrasion-resistant outer protective layer 1 provides durable protection. When exposed to high temperatures, the ceramicized silicone rubber flame-retardant filler layer 2 and the halogen-free flame-retardant polyolefin inner protective layer 9 together form a flame-retardant barrier, ensuring that the cable can operate stably and reliably in various harsh environments.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
