[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0019] For example, Figures 1 to 4As shown, this utility model provides a low-smoke, halogen-free, high flame-retardant B1-grade high-speed network cable, including a network cable body 1. The network cable body 1 includes an outer sheath 10 on the outermost layer and a shielding layer 11 on the inner side. A flame-retardant filling layer 9 is filled between the shielding layer 11 and the outer sheath 10. The outer wall of the outer sheath 10 is wrapped with a reinforcing wire mesh. A cross skeleton 3 is installed inside the outer sheath 10. A ring array of wire cores 2 is installed on the surface of the cross skeleton 3. By setting the outer sheath 10, the flame-retardant performance of the network cable body 1 can be improved, while ensuring that the network cable body 1 has a certain elasticity to prevent breakage. At the same time, in conjunction with the flame-retardant filling layer 9, it can absorb and consume a large amount of heat in the event of a fire, prevent the spread of flames, and reduce the generation of smoke. The outer sheath 10 can shield low-frequency electromagnetic interference, reducing the impact of external electromagnetic interference on the network cable signal transmission. The braided mesh wrapped on the outside of the outer sheath 10 can improve the tensile strength of the network cable body 1.

[0020] It should be noted that the outer sheath 10 is made of low-smoke, halogen-free, high flame-retardant polyolefin material, and the flame-retardant filler layer 9 is made of a mixture of inorganic flame-retardant material and organic flame retardant.

[0021] like Figures 1 to 4 As shown, the outer side of the core 2 is wrapped with an insulating layer 12, and the ends of the cross frame 3 are fixedly connected with arc blocks 7. The surface of the arc blocks 7 is provided with vertical grooves in a trapezoidal structure. The inner side of the shielding layer 11 is fixed with a buffer layer 8. The surface of the buffer layer 8 has several sets of grooves in a ring array. The arc blocks 7 can effectively limit the core 2, and the vertical grooves on the surface of the arc blocks 7 can make the cross frame 3 bend to a certain extent, avoiding rigid contact between the core 2 and the arc blocks 7, which would affect the service life of the core 2.

[0022] Several sets of rubber blocks 4 are symmetrically fixed on the outer surface of the network cable body 1. Magnetic blocks 5 are embedded inside the rubber blocks 4 on both sides. The slots containing the magnetic blocks 5 have a T-shaped cross-section. Shielding spacers 6 are installed inside the magnetic blocks 5. When storing the network cable body 1, the network cable is spirally wound into a cylindrical shape. The magnetic blocks 5 on adjacent network cables will attract each other, thus allowing adjacent network cable bodies 1 to be simply connected and positioned. Figure 2 As shown, the network cable body 1 is stacked vertically, which facilitates the storage of the network cable body 1. The shielding spacer 6 can isolate the magnetic field of the magnetic block 5 to a certain extent, and at the same time, the shielding layer 11 reduces the interference of the magnetic block 5 on the network signal.
