[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the present embodiment, in the process of high-speed data transmission, the integrity of the signal is of vital importance. Shielded data cable can reduce the attenuation and distortion of the signal, ensure the stability and accuracy of the network signal, and is widely favored by people. Through the setting of the low-smoke layer 301, it is effectively prevented that the data cable releases a large amount of smoke and pollutes the environment when a fire is caused by a short circuit. The low-smoke layer 301 is made of magnesium hydroxide, which is an inorganic metal flame retardant. During the combustion of the cable, magnesium hydroxide can absorb a large amount of heat and undergo a decomposition reaction, which can reduce the temperature of the combustion area. At the same time, the water vapor produced by the decomposition of magnesium hydroxide can dilute the concentration of the combustible gas, thereby reducing the amount of smoke generated, thereby effectively reducing the harm to the human body and the environment. In order to prevent the shielded data cable from catching fire, the low-smoke layer 301 is made of magnesium hydroxide. Magnesium hydroxide is an inorganic metal flame retardant. During the combustion of the cable, magnesium hydroxide can absorb a large amount of heat and undergo a decomposition reaction, which can reduce the temperature of the combustion area. At the same time, the water vapor produced by the decomposition of magnesium hydroxide can dilute the concentration of the combustible gas, thereby reducing the amount of smoke generated, thereby effectively reducing the harm to the human body and the environment. The cable is damaged by external factors such as pulling and bending during use. First of all, the strength of the data cable itself is further improved through the setting of the armor layer 302. The armor layer 302 is woven from steel wires to provide the cable with excellent tensile strength to prevent the shielded data cable from being broken by people's pulling due to its own gravity during installation. It can also prevent rodents from gnawing the cable. In addition, the armor layer 302 also has a certain flexibility and can adapt to the bending of the cable to a certain extent. Since there is a certain gap between the steel wires, when the data cable expands due to heat, there is a certain expansion space, so that the data cable will not be damaged due to excessive internal stress. The reinforcement layer 303 increases the physical strength of the data cable. The reinforcement layer 303 is made of aramid Aramid fiber has super high strength, good heat resistance and chemical resistance. In data cables, aramid fiber can effectively enhance the tensile strength of data cables, so that data cables will not break easily when subjected to large tensile forces. In addition, since aramid fiber has high strength and modulus, its texture is relatively tough. Although rodents have sharp teeth, they will encounter greater resistance when gnawing on aramid fiber. This high-strength characteristic enables aramid fiber to maintain its integrity when facing rodents. The reinforcement layer 303 can ensure that the data cable works normally in a complex mechanical environment. At the same time, the chemical stability of aramid fiber enables it to resist the erosion of various chemical substances and can maintain its durability in harsh chemical environments. The performance of the data cable is maintained, thereby further improving the practicality of the data cable. Since the buffer layer 304 is made of natural rubber, natural rubber has excellent elasticity and flexibility, which enables the data cable to buffer external mechanical stress well. When the cable is squeezed or bent, the buffer layer 304 can absorb and disperse the stress through its own elastic deformation, thereby effectively reducing the damage to the internal structure of the data cable due to frequent bending. The setting of the buffer layer 304 can effectively prevent the data cable from being damaged during the complete process. The aluminum tape 305 can effectively prevent external water vapor from entering the interior of the data cable. The aluminum tape 305 is a relatively dense material, which can serve as a physical barrier to prevent moisture from invading the interior of the data cable.During the long-term use of the data cable, especially in a humid environment, moisture can easily enter the cable through the tiny gaps in the outer skin of the data cable. The presence of the aluminum tape 305 can greatly reduce the occurrence of this situation. The aluminum tape 305 helps to keep the inside of the data cable dry and reduce the risk of leakage of the data cable. The mechanical protection layer 306 located on the outermost layer of the data cable is made of chloroprene rubber. Neoprene has excellent flexibility and elasticity. When the data cable is bent and stretched, the outermost mechanical protection layer 306 can adapt well to the changes in the shape of the data cable so that it will not break easily. In addition, chloroprene rubber has excellent weather resistance and chemical corrosion resistance, and can resist the erosion of ozone, ultraviolet rays and acid and alkali to the data cable, thereby further extending the service life of the data cable. The multi-layer physical protection of the shielded data cable by the protective component 3 can further improve the strength of the data cable itself, effectively prevent the damage of the data cable caused by external environmental factors, and solve the problem that the traditional shielded data cable in the prior art has low self-protection strength and is easily physically damaged and cannot be used normally.

[0024] like Figure 1-Figure 2 and Figure 5-Figure 6 As shown, the anti-gnaw component 2 includes a first flame retardant layer 201 for preventing the spread of flames, the first flame retardant layer 201 is made of aluminum hydroxide, the outer surface of the first flame retardant layer 201 is provided with a rubber layer 202 for improving the elasticity of the cable itself, a plurality of elastic rods 203 are provided on the outer surface of the rubber layer 202, the elastic rods 203 are made of rubber material, one end of the plurality of elastic rods 203 are provided with a rubber sleeve 204, the interior of the plurality of rubber sleeves 204 are filled with rat poison for preventing mice from gnawing, an anti-break layer 205 for protecting the plurality of rubber sleeves 204 is provided between the outer surfaces of the plurality of rubber sleeves 204, the outer surface of the anti-break layer 205 is provided with a second flame retardant layer 206 for burning the rubber sleeves 204, the second flame retardant layer 206 is made of chlorinated paraffin, and the second flame retardant layer 206 is provided inside the low smoke layer 301.

[0025] In this embodiment, when the cable surface is damaged and the protective component 3 is damaged, in order to prevent rodents from gnawing on the data cable, rat poison is filled inside the rubber sleeve 204 so that when the rodent bites through the rubber sleeve 204, the rat poison will work inside the rodent, causing damage to the rodent's body functions, causing physical discomfort or even death, so that the rodent will no longer continue to gnaw the cable, thereby achieving the purpose of protecting the data cable. Since rat poison has a certain toxicity, in order to prevent a large amount of rat poison from leaking out of the cable, a small amount of rat poison is placed inside multiple rubber sleeves 204 respectively, so that the rat poison is evenly distributed in a small amount. At the same time, in order to prevent the rat poison from leaking out when the cable is bent or pulled, the elastic rod 203 is set so that the rubber sleeve 204 can withstand strong pulling and complete. In addition, the elastic rod 203 is made of rubber material and has strong elasticity. Figure 6 As shown, the inner wall of the anti-breakage layer 205 is provided with a plurality of arc grooves, the purpose of which is to protect the plurality of rubber sleeves 204 from being squeezed and damaged. In addition, the anti-breakage layer 205 is made of PVC and has good flexibility and mechanical strength. Its flexibility enables the anti-breakage layer 205 to adapt to the bending and deformation of the cable to a certain extent, thereby protecting the rubber sleeve 204. The first flame retardant layer 201 and the second flame retardant layer 206 are provided to prevent the rubber sleeve 204 from being damaged when the cable is on fire due to internal or external reasons. The first flame retardant layer 201 and the second flame retardant layer 206 are respectively made of aluminum hydroxide and chlorinated paraffin, which can reduce the temperature of the combustion area, thereby achieving a flame retardant effect, thereby preventing rat poison from being released into the environment due to cable combustion, and also achieving a flame retardant effect on the data cable. The self-protection ability of the data cable is further improved through the function of the anti-gnaw component 2.

[0026] like Figure 1-Figure 4As shown, the shielding assembly 1 includes a plurality of cores 101, the outer surfaces of the plurality of cores 101 are all provided with a lubricating layer 102 for reducing cable friction, a filling layer 103 for protecting and preventing the plurality of cores 101 from displacement is provided between the outer surfaces of the plurality of lubricating layers 102, the filling layer 103 is made of polypropylene material, the outer surface of the filling layer 103 is provided with an insulating layer 104 for preventing current leakage, the insulating layer 104 is made of cross-linked polyethylene material, the outer surface of the insulating layer 104 is provided with a shielding layer 105 for preventing external electromagnetic interference, the shielding layer 105 is made of copper foil The outer surface of the shielding layer 105 is provided with an anti-interference layer 106 for preventing the internal signal radiation of the cable from interfering with the external equipment. The anti-interference layer 106 is made of conductive plastic material. The outer surface of the anti-interference layer 106 is provided with an aluminum foil 107 for forming a continuous shielding for the cable. The outer surface of the aluminum foil 107 is provided with a copper mesh 108 for electrostatic protection. The outer surface of the copper mesh 108 is provided with an anti-corrosion layer 109 for preventing the cable from chemical corrosion. The anti-corrosion layer 109 is made of fluoroplastic material. The anti-corrosion layer 109 is arranged inside the first flame retardant layer 201.

[0027] In this embodiment, in order to ensure the shielding effect of the shielded data cable, firstly, the lubricating layer 102 is sheathed on the outer surface of the core 101 to make the shielded data cable easier to bend, because the lubricating layer 102 can make the relative sliding between the parts of the core 101 smoother, so that the data cable can still maintain good performance under frequent bending, thereby extending the service life of the cable. The main component of the lubricating layer 102 is graphite powder, and the graphite powder has a layered crystal structure. When subjected to external force, these layered structures can slide against each other, thereby lubricating the core 101. In addition, the filling layer 103 is provided to effectively prevent the displacement of multiple cores 101. The filling layer 103 is made of polypropylene material. Polypropylene It is lightweight and will not add too much weight to the data cable, making it convenient to lay and transport the data cable. It can also play a structural support role inside the cable, effectively preventing extrusion and displacement between multiple cores 101. The insulating layer 104 is made of cross-linked polyethylene. Cross-linked polyethylene forms a mesh structure between polyethylene molecular chains through chemical cross-linking. This material has better insulation performance, especially in high-voltage environments. It can effectively prevent current leakage in data cables and can withstand higher electric field strengths. The shielding layer 105 can effectively block external electromagnetic interference signals from entering the interior of the shielded data cable. The shielding layer 105 can reflect external electromagnetic interference signals back to ensure that the data signal is stable and accurate inside the cable. The anti-interference layer 106 is made of conductive plastic material. Conductive plastic is a new type of anti-interference material. It is made by adding carbon black to a plastic matrix. Conductive plastic has good flexibility and processability, and can meet the complex shape and frequent bending requirements of data cables to achieve customized electromagnetic shielding effects. In addition, through the setting of aluminum foil 107, a continuous shielding can be formed for the data cable. Aluminum foil 107 has good conductivity and plays an electromagnetic shielding role in the data cable. When the external electromagnetic interference signal encounters the aluminum foil 107, it will be reflected back by the aluminum foil 107, thereby preventing the external interference signal from entering the cable, thereby ensuring the transmission quality of the data signal in the cable. In the case of a complex surrounding electromagnetic environment, if In places with a large number of electrical equipment and radio communication equipment, the copper mesh 108, as a good conductor, can provide electromagnetic shielding for the data cable. When external electromagnetic interference contacts the copper mesh 108, an induced current will be generated on the copper mesh 108 according to the principle of electromagnetic induction. This induced current will generate an electromagnetic field in the opposite direction of the external interference electromagnetic field, thereby offsetting the external interference and preventing it from entering the data cable. Using cables with copper mesh 108 shielding can effectively reduce the impact of these interferences on internal signal transmission and ensure the accuracy and stability of the signal. The anti-corrosion layer 109 is made of fluoroplastic material and can serve as a barrier for the data cable to prevent acidic substances from contacting the core 101 and protect the integrity and conductivity of the data cable.Fluoroplastic is a high-performance anti-corrosion material with extremely strong chemical stability. It can withstand almost all chemical substances, including strong acids, strong alkalis, and strong oxidants. It also has excellent high and low temperature resistance and can maintain stable performance in a wide temperature range. In some extremely harsh chemical environments, the anti-corrosion layer 109 can ensure the safe operation of the data cable. Through the function of the shielding component 1, the shielding performance of the shielded data cable is further improved.

[0028] The method of use and working principle of the device: In order to ensure the shielding effect of the shielded data cable, first, a lubricating layer 102 is sheathed on the outer surface of the wire core 101 to make the shielded data cable easier to bend, because the lubricating layer 102 can make the relative sliding between the parts of the wire core 101 smoother, so that the data cable can still maintain good performance in the case of frequent bending, thereby extending the service life of the cable. The setting of the filling layer 103 can effectively prevent the displacement of multiple wire cores 101, facilitate the laying and transportation of data cables, and can also play a role of structural support inside the cable, which can effectively prevent the extrusion and displacement between multiple wire cores 101. The insulating layer 104 can effectively prevent the current leakage of the data cable and can also withstand higher The electric field strength of the shielding layer 105 can effectively block the external electromagnetic interference signal from entering the inside of the shielded data cable. The shielding layer 105 can reflect the external electromagnetic interference signal back to ensure that the data signal is stably and accurately transmitted inside the cable. The anti-interference layer 106 can meet the complex shape and frequent bending requirements of the data cable to achieve a customized electromagnetic shielding effect. In addition, through the setting of the aluminum foil 107, a continuous shielding can be formed for the data cable. The aluminum foil 107 has good conductivity and plays an electromagnetic shielding role in the data cable. When the external electromagnetic interference signal encounters the aluminum foil 107, it will be reflected back by the aluminum foil 107, thereby preventing the external interference signal from entering the cable, ensuring the transmission quality of the data signal in the cable, and surrounding In the case of a complex electromagnetic environment, if there are a large number of electrical equipment and radio communication equipment, the copper mesh 108, as a good conductor, can perform electromagnetic shielding on the data cable. When the external electromagnetic interference contacts the copper mesh 108, an induced current will be generated on the copper mesh 108 according to the principle of electromagnetic induction. This induced current will generate an electromagnetic field in the opposite direction of the external interference electromagnetic field, thereby offsetting the external interference and preventing it from entering the data cable. The use of cables with copper mesh 108 shielding can effectively reduce the impact of these interferences on internal signal transmission, ensuring the accuracy and stability of the signal. The anti-corrosion layer 109 can serve as a barrier for the data cable to prevent acidic substances from contacting the core 101, protecting the integrity and The electrical conductivity and anti-corrosion layer 109 can ensure the safe operation of the data cable. By filling rat poison inside the rubber sleeve 204, when a rodent bites through the rubber sleeve 204 and ingests the rat poison, the rat poison will act inside the rodent, causing damage to the rodent's body functions, causing physical discomfort or even death of the rodent, so that the rodent will no longer continue to gnaw the cable, thereby achieving the purpose of protecting the data cable. Since rat poison has certain toxicity, in order to prevent a large amount of rat poison leakage in the cable, a small amount of rat poison is placed inside multiple rubber sleeves 204 respectively, so that the rat poison is evenly distributed in a small amount. At the same time, in order to prevent the rat poison from leaking when the cable is bent or pulled,The elastic rod 203 is arranged so that the rubber sleeve 204 can withstand strong pulling and is completely. The inner wall of the anti-breakage layer 205 is provided with a plurality of arc grooves, the purpose of which is to protect the plurality of rubber sleeves 204 and prevent them from being squeezed and damaged. The first flame retardant layer 201 and the second flame retardant layer 206 can prevent the rubber sleeve 204 from being damaged when the cable is on fire due to internal or external reasons. The arrangement of the low smoke layer 301 can effectively prevent the data cable from releasing a large amount of smoke and polluting the environment when a fire is caused by a short circuit. The arrangement of the armor layer 302 further improves the strength of the data cable itself, provides the cable with excellent tensile strength, prevents the shielded data cable from being broken due to its own gravity and people's pulling during the installation process, and also prevents rodents from gnawing the cable. In addition, the armor layer 302 also has a certain flexibility, which can adapt to the bending of the cable to a certain extent. There is a certain gap between them. When the data cable expands due to heat, there is a certain expansion space, so that the data cable will not be damaged due to excessive internal stress. The reinforcement layer 303 increases the physical strength of the data cable and enhances the tensile strength of the data cable, so that the data cable will not break easily when subjected to a large tensile force. The buffer layer 304 can effectively prevent the data cable from being damaged during the complete process. The aluminum tape 305 can effectively prevent external water vapor from entering the interior of the data cable, especially in a humid environment. Water can easily enter the cable through the tiny gaps in the outer skin of the data cable. The presence of the aluminum tape 305 can greatly reduce the occurrence of such mine robbery. The aluminum tape 305 helps to keep the inside of the data cable dry and reduce the risk of leakage of the data cable. The mechanical protection layer 306 located on the outermost layer of the data cable can adapt well to the changes in the shape of the data cable, so that it will not break easily. ,
