[0019] Example 1

[0020] Figure 1 This is a schematic diagram of the cross-sectional structure of a five-core shielded anti-interference cable provided in an embodiment of this utility model. Figure 2 for Figure 1 Another cross-sectional structural diagram of a five-core shielded anti-interference cable. Please refer to... Figure 1 , Figure 2The five-core shielded anti-interference cable provided in this embodiment includes a first core wire group 100, a second core wire group 200, a filler rope 300, a fixing layer 400, a shielding layer 500, a protective layer 600, and a sheath 700. The first core wire group 100 includes a first oxygen-free copper wire 110 and a first insulation layer 120. The surface of the first oxygen-free copper wire 110 is covered with the first insulation layer 120, and three first oxygen-free copper wires 110 covered with the first insulation layer 120 are arranged and twisted together to form the first core wire group 100. The second core wire group 200 includes a second oxygen-free copper wire 210, a second insulation layer 220, a drain wire 230, and a composite layer 24. 0. The surface of the second oxygen-free copper wire 210 is covered with the second insulation layer 220. Two second oxygen-free copper wires 210 covered with the second insulation layer 220 and one drainage wire 230 are wrapped in the composite layer 240 to form the second core wire group 200. The fixing layer 400 is wrapped around the first core wire group 100 and the second core wire group 200. The shielding layer 500 is wrapped around the outside of the fixing layer 400. The sheath 700 is wrapped around the outside of the shielding layer 500. The filling rope 300 is filled in the gap between the first core wire group 100, the second core wire group 200 and the fixing layer 400.

[0021] Specifically, the composite layer 240 of this utility model includes an aluminum foil layer and a non-woven fabric layer. The composite use of aluminum foil and non-woven fabric mainly improves cable performance, electromagnetic shielding, and signal protection through material synergy. The aluminum foil layer effectively shields high-frequency signal interference by reflecting and absorbing electromagnetic interference, while the non-woven fabric, as a support layer, enhances the mechanical stability of the aluminum foil and prevents tearing. The flexibility and abrasion resistance of the non-woven fabric compensate for the weakness of aluminum foil, making the cable more durable in bending or moving scenarios. At the same time, the non-woven fabric can wrap the edges of the aluminum foil, reducing the risk of burrs during installation.

[0022] It should be noted that both the first insulating layer 120 and the second insulating layer 220 of this utility model are Teflon insulating layers. Teflon insulating layers have high temperature resistance and can remain stable in the range of -100℃ to 250℃, making them particularly suitable for high-temperature environments; they have corrosion resistance and can resist corrosion from strong acids, strong alkalis, organic solvents, and oxidants, making them suitable for chemical equipment and corrosive environments; they have flame-retardant properties, are not easily ignited, and are self-extinguishing upon removal of the flame, providing high safety and making them suitable for fire-fighting equipment and other scenarios with high fire protection requirements; they are resistant to friction and aging, have a smooth and wear-resistant surface, and a long service life, making them suitable for occasions with frequent bending or sliding contact; they have high insulation resistance and low high-frequency loss.

[0023] The filler rope 300 of this utility model is a PP mesh rope filler rope. The PP mesh rope fills the gaps after the cable core wires are twisted together, ensuring that the cable cross-section is a complete circle and avoiding eccentricity. This structural stability is crucial for subsequent processing. The high strength characteristics of PP material can improve the cable's tensile and bending resistance. In hard processing steps such as braiding or armoring, the PP mesh rope filler can also buffer external pressure and prevent damage to the cable core.

[0024] The fixing layer 400 of this utility model is a transparent polyester tape, which plays a role in mechanical protection and fixing. The polyester tape has high strength and can effectively bind and fix the cable core wires. It also has the function of insulation and isolation. Located between the conductor and the shielding layer, the polyester tape can act as an insulating medium to prevent short circuits.

[0025] The shielding layer 500 of this invention is a tin-plated shielding layer. The tin-plated shielding layer significantly improves the reliability and signal integrity of special cables in complex environments through its anti-oxidation, corrosion resistance, and optimized electromagnetic shielding performance. The tin-plated copper wire requires no additional oxide layer treatment and can be directly soldered, reducing process difficulty. It also possesses grounding stability, ensuring safe current conduction even when the core wire is damaged.

[0026] The protective layer 600 of this utility model is a non-woven fabric protective layer. In this cable, the non-woven fabric serves as both a physical protective layer and a functional reinforcing material. The non-woven fabric wrapped around the outside of the shielding layer provides additional mechanical protection. Its fibrous mesh structure can effectively disperse external stress, preventing damage to the shielding layer during cable bending, stretching, or installation, and avoiding breakage of the shielding layer due to frequent movement. As a filling material, the non-woven fabric also fills the gaps inside the cable, reduces friction between the shielding layer and the sheath layer, and enhances the overall stability of the cable structure, reducing the impact of vibration and shock on the shielding performance.

[0027] The sheath 700 of this utility model is a polyurethane sheath. Polyurethane material has excellent mechanical properties, high wear resistance and tear resistance, making it suitable for environments with frequent bending or friction. It is not easy to crack and extends the service life of the cable. It has excellent flexibility and elasticity, and remains soft at low temperatures, making it suitable for dynamic bending scenarios (such as robots and automated equipment). In addition, polyurethane material has stable electrical properties, high insulation resistance, and excellent dielectric properties, ensuring the quality of signal transmission.

[0028] As can be seen from the above description, the advantages of this utility model are:

[0029] The five-core shielded anti-interference cable provided by this utility model has high wear resistance and tear resistance, excellent flexibility and elasticity, and is applicable to a variety of scenarios. For example, in the field of industrial automation, it can be used as drag chain cables, robot joint cables, etc.; in the field of mobile devices, it can be used as cranes, logistics conveying systems, etc. The cable of this utility model has a tin-plated shielding layer, which greatly improves reliability and signal integrity and can be used for high-frequency communication, industrial control signal transmission, etc. Under high reliability requirements, the tin-plated layer ensures signal transmission stability and can also be used in medical equipment. The drainage line design is also suitable for outdoor equipment in harsh environments such as mines and ships.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model 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 utility model should be included within the protection scope of this utility model.
