[0029] Network cables are used to transmit information within a network. Commonly used network cables include twisted-pair cables, coaxial cables, and fiber optic cables. Twisted-pair cables are made of two insulated copper conductors twisted together at a certain density and then sheathed in a conduit. With the rapid development of information technology, network communications have become an indispensable part of modern society's infrastructure. As a key medium for network transmission, the performance of network cables directly affects the speed, stability, and security of data transmission.

[0030] In related technologies, network cables are typically made by sheathing four pairs of twisted-pair cables through a tube. This type of network cable is prone to damage due to insufficient mechanical strength, resulting in poor stability and reliability in network signal transmission and a short service life. This makes it difficult to meet the wiring design requirements of different environments. For example, some scenarios require frequent bending, pulling, squeezing, and other complex operations of the network cable. Some network cables also incorporate a high-rigidity skeleton as a central support structure to improve structural strength. However, this type of network cable can only adapt to straight wiring environments and cannot be effectively bent, resulting in a limited range of applications.

[0031] Furthermore, with the rise of emerging technologies like big data, cloud computing, and the Internet of Things, the demand for network bandwidth and transmission speeds is increasing. Traditional network cables are struggling to meet these high-performance demands. Therefore, developing a robust network cable that combines high strength and toughness while effectively guaranteeing signal transmission quality has become a pressing technical challenge for the industry.

[0032] The following reference Figure 1 To the attached Figure 5 , describing the strong and tough network cable of the embodiment of the utility model, which can effectively improve the overall strength and toughness of the network cable through the unique internal bracket structure and has strong adaptability.

[0033] Reference Figures 1 to 5 A tough network cable according to an embodiment of the present invention includes:

[0034] The protective cover 1000 is in the shape of a circular cylinder, that is, the protective cover 1000 is a cylinder with a circular cross section;

[0035] The inner bracket 2000 is arranged in the protective cover 1000. The inner bracket 2000 includes a skeleton 2100, a central rib 2200 and an outer rib 2300. The skeleton 2100 is provided with n, n is an integer greater than 1, and the central rib 2200 is provided with (n-1). The opposite ends of each central rib 2200 are respectively connected to two adjacent skeletons 2100. Each skeleton 2100 and the central rib 2200 are alternately arranged along the extension direction of the protective cover 1000. The central rib 2200 is parallel to the extension direction of the protective cover 1000. The skeleton 2100 is in the shape of a cross column, that is, the skeleton 2100 is a column with a cross-shaped cross section, and the outer ribs There are four ribs 2300, and the four outer ribs 2300 are parallel to the extension direction of the protective cover 1000. The four outer ribs 2300 surround each frame 2100 along the extension direction of the protective cover 1000. The four ends of each frame 2100 are respectively connected to the four outer ribs 2300, that is, the same outer rib 2300 connects the ends of each frame 2100 in the same direction. The four outer ribs 2300 respectively connect the ends of each frame 2100 in four directions. Four receiving cavities 2101 parallel to the extension direction of the protective cover 1000 are formed between the frame 2100 and the protective cover 1000.

[0036] There are four twisted pair groups 3000, and the four twisted pair groups 3000 are respectively arranged in four receiving cavities 2101, which can effectively reduce signal interference between lines, effectively improve the clarity and stability of data transmission, and effectively ensure the quality of signal transmission and good signal transmission security.

[0037] By configuring the inner bracket 2000 to include a plurality of skeletons 2100 and central ribs 2200 alternately connected along the extension direction of the protective cover 1000, the radial dimension of the inner bracket 2000 can fluctuate along the extension direction of the protective cover 1000. When the network cable bends during use, the central ribs 2200 can effectively provide space for the skeletons 2100. This ensures bending performance while also maintaining the structural strength and toughness of the network cable. The network cable has strong adaptability and can meet the wiring requirements of network communication systems in different environments. In addition, the structure in which the skeletons 2100 are arranged at intervals and connected by the central ribs 2200 can effectively save materials, thereby effectively reducing the production cost of the network cable.

[0038] The inner bracket 2000 adopts a cross-shaped columnar structure, which can provide a stable support foundation. In addition, the four outer ribs 2300 are respectively connected to the four ends of each skeleton 2100, which can effectively improve the stability of the overall structure of the inner bracket 2000. The inner bracket 2000 as a whole is a stable three-dimensional network structure. This network line structure is stable and strong. When subjected to external forces, it can effectively disperse stress and avoid single-point excessive force causing network line breakage. It can significantly improve the overall structure's anti-bending, anti-stretching and anti-extrusion properties, have a long service life, and can effectively reduce maintenance costs.

[0039] Moreover, the arrangement of the four outer ribs 2300 can provide the inner bracket 2000 with a continuous peripheral guiding structure along the extension direction of the protective cover 1000. During the extrusion process of the protective cover 1000 of the network cable, the outer ribs 2300, as a continuous structure, are in contact with the mold guide of the extruder, which can effectively simplify the alignment operation, thereby effectively improving the smoothness of the preparation process and effectively improving the processing efficiency.

[0040] Specifically, the twisted pair wire group 3000 includes two insulated copper wires twisted together. The insulated copper wire refers to a copper wire structure with an insulating layer coated on the surface.

[0041] It can be understood that the skeleton 2100 includes a central axis 2110 and four double-rod support arms 2120. The central axis 2110 is coaxial with the central rib 2200, that is, they are collinear, and the central axis 2110 is parallel to the extension direction of the protective cover 1000. The central rib 2200 is connected between two adjacent central axes 2110. The four double-rod support arms 2120 are respectively connected to the four sides of the central axis 2110. The four double-rod support arms 2120 are rotationally symmetrical about the central axis 2110, that is, the four double-rod support arms 2120 are equally spaced around the central axis 2110. The double-rod support arms 2120 include two support rods 2121 that are both perpendicular to the central axis 2110. The opposite ends of the support rod 2121 are respectively connected to the central axis 2110 and the outer rib 2300.

[0042] By setting the edge of the skeleton 2100 to be composed of four double-rod support arms 2120, the double-rod structure can effectively improve the stability of the skeleton 2100 structure, and can effectively improve the toughness of the skeleton 2100 in the diameter direction of the protective cover 1000, and can effectively improve the anti-twisting and anti-extrusion capabilities of the skeleton 2100, and can further improve the strength and toughness of the overall structure of the network cable.

[0043] It can be understood that the central axis 2110 is prismatic, and the two support rods 2121 in each double-rod support arm 2120 are respectively connected to the opposite sides of each edge of the central axis 2110. By setting the specific two support rods 2121 of each double-rod support arm 2120 to be respectively connected to the adjacent two side surfaces of the central axis 2110, the force of the double-rod support arm 2120 on each position of the central axis 2110 can be effectively dispersed, the force-bearing performance of the overall structure can be effectively improved, and the strength and toughness of the overall structure can be effectively improved.

[0044] It can be understood that the outer rib 2300 is in the shape of a semicircular column, the arc surface of the outer rib 2300 is set toward the protective cover 1000, the arc surface of the outer rib 2300 is in contact with the inner wall of the protective cover 1000, and each support rod 2121 is connected to the plane of the corresponding outer rib 2300 at one end away from the center axis 2110.

[0045] By setting the outer rib 2300 to a semicircular columnar structure, it can fully adapt to the different structures on both sides. The flat part of the outer rib 2300 is used to connect the end of the support rod 2121, which can not only effectively improve the stability of the connection structure between the outer rib 2300 and the support rod 2121, but also effectively save materials and thus effectively reduce the production cost of the network cable. By setting the other side of the outer rib 2300 to a circular arc surface for contacting the inner wall of the protective cover 1000, the contact area between the outer rib 2300 and the protective cover 1000 can be effectively increased, and the probability of damage caused by mutual squeezing between the two can be effectively reduced.

[0046] It can be understood that the length of the double-rod support arm 2120 is L1, and accordingly, the length of the support rod 2121 is also L1, and the length of the central rib 2200 is L2, 2L1>L2. By setting the length of the central rib 2200 to be less than the sum of the lengths of the support arms on the adjacent two sides, when the network line bends, the inner bracket 2000 bends synchronously. Due to the stable cross structure of the skeleton 2100, the bending position is the central rib 2200. When the central rib 2200 bends, the skeletons 2100 connected on the adjacent two sides rotate close to the center of the central rib 2200 until the two skeletons 2100 contact. At this time, the bending position of the central rib 2200 is a critical position, which can effectively limit the bending angle of the central rib 2200, effectively avoid damage to the network line due to excessive bending, and effectively extend the service life of the network line.

[0047] It can be understood that the central rib 2200 is cylindrical. By setting the cylindrical central rib 2200, the bending performance of the central rib 2200 in all directions can be effectively improved, thereby effectively improving the bending and deformation ability of the network cable, and further improving the usable range of the network cable.

[0048] It can be understood that the outer rib 2300 is a silicone strip. Silica gel, also known as silica gel, has good tensile strength and tear strength, which can effectively improve the mechanical properties of the outer rib 2300, thereby effectively improving the stability of the inner bracket 2000 structure.

[0049] Specifically, the inner skeleton 2100 and the central rib 2200 can be made of silicone or other plastic structures. Depending on the actual materials used, the inner bracket 2000 is extruded by a plastic extruder, which can be single-color extrusion or multi-color co-extrusion, and can realize extrusion molding of single or multiple materials.

[0050] It can be understood that a shielding net 1100 is provided in the protective cover 1000, and the shielding net 1100 surrounds the four twisted pair groups 3000, which can effectively improve the anti-interference performance of each twisted pair group 3000 to external signals, and can effectively improve the clarity and stability of signal transmission. The mesh structure as the skeleton 2100 of the protective cover 1000 can effectively improve the toughness of the protective cover 1000 structure, and at the same time can effectively reduce the investment cost of the shielding material, thereby effectively reducing the production cost of the network cable.

[0051] Specifically, the shielding net 1100 is an aluminum foil net, and the aluminum foil has good shielding function.
