In the present utility model, the coaxial cable 100 is used for transmitting video signals and the like, and the twisted pair 200 is used for transmitting digital data signals and the like. The metallic foil shielding layer 400 provides the twisted pair 200 and the coaxial cable 100 with a total shielding effect, and the coaxial cable 100 and the twisted pair 200 themselves have a corresponding shielding effect. The filler layer 500 and the armor layer 600 provide a primary strength effect, while the second protective sheath 700 provides an outer sealing and protection effect for the entire artificial intelligence data transmission cable. The second insulating layer 130 may be solid or porous, but is relatively dense with respect to the first insulating layer 120. The density of the first insulating layer 120 is relatively low compared to the density of the second insulating layer 130 in the coaxial cable 100, and thus the density of the first insulating layer 120 is relatively low; at this time, the first insulating layer 120 mainly provides a deformation effect, so that the abnormal deformation amount of the second insulating layer is reduced, and the corresponding second insulating layer 130 mainly provides a shaping effect, so as to ensure that the shape of the metal foil shielding layer 400 is more regular.

In one embodiment, the first insulating layer 120 is a foamed structure, and the second insulating layer 130 is a solid structure.
In the foregoing embodiment, in order to make the deformation of the first insulating layer 120 more uniform, the density thereof is 0.3 to 0.7 times that of the second insulating layer 130. In this embodiment, in order to make the first insulating layer 120 not have abnormal wrinkles during bending deformation, so as to affect the electrical characteristics of the metal foil shielding layer 400, the first insulating layer 120 is configured to be a foamed structure, so that in the bending laying process of the artificial intelligence data transmission cable, the gas in the first insulating layer 120 is foamed to enable the first insulating layer 120 to achieve a relatively stable bending structure, and the solid structure of the corresponding second insulating layer 130 can also ensure that the shape of the metal foil shielding layer 400 attached to the first insulating layer is more uniform.

The polyethylene material can be used as an insulating material well, and has the characteristics of simple processing and mature process.
Referring to fig. 1, in one embodiment, the filler layer 500 is a synthetic polymer material bundle or a natural polymer material bundle.
Compared with the whole formed by extruding and wrapping a plurality of coaxial cables 100 and a plurality of twisted pairs 200 by using a polymer material, in the embodiment, the composite polymer material bundles or the natural polymer material bundles are adopted for filling and wrapping, and the cooling process is not existed, and the filling effect in each gap is better. The processing mode of the synthetic polymer material beam or the natural polymer material beam can be realized by reasonably inserting and distributing on the distribution board. The filler layer 500 may be selected from PP ropes, hemp ropes, fiberglass, or the like.

The difficulty in forming the insulating effect on the metal foil shielding layer 400 is low and the effect is easily ensured with respect to forming the insulating effect on the armor layer 600.
In one embodiment, the metal foil shielding layer 400 is formed by wrapping a metal foil tape, and the outer side of the metal foil shielding layer 400 is covered with a hot melt adhesive layer for forming the first insulating layer 120.
Compared with a dragging and packing mode, the metal foil shielding layer 400 is formed in a metal foil tape wrapping mode, the stability of the metal foil shielding layer 400 is high, and the outer hot melt adhesive layer is covered on the outer side of the metal foil tape, so that the outer hot melt adhesive layers are mutually spliced in the wrapping process of the metal foil tape, and the outer hot melt adhesive layer is melted under the action of the cable heater to form the first insulating layer 120. The hot melt adhesive layer can be made of polyurethane and other materials.
In one embodiment, the inner side of the metal foil shielding layer 400 is covered with a hot melt adhesive layer, and the inner wall of the metal foil shielding layer 400 abuts against the twisted pair 200.

In one embodiment, the twisted pair 200 has a shielding sheath around its periphery, the shielding sheath being wrapped with a shielding metal tape, the inner and outer layers of the shielding metal tape being provided with a hot melt adhesive layer.
The twisted pair 200 is required to have a separate shield, and the above self-adhesive shield can achieve the fixing effect of two sub-wires in the twisted pair 200 and the fixing effect of the whole twisted pair 200, so that the structural stability of the twisted pair 200 is enhanced.
In one embodiment, the hot melt adhesive layer is made of ethylene-vinyl acetate copolymer hot melt adhesive.
The material of eva (ethylene-vinyl acetate) can realize better bonding effect, and the processing technology is simple and mature.
Referring to fig. 1, in one embodiment, the coaxial cables 100 are three in number and are arranged in a regular triangle, the twisted pairs 200 are greater than three in number, and three of the twisted pairs 200 are respectively arranged in grooves formed on the outer sides of adjacent coaxial cables 100.
In this embodiment, the three coaxial cables 100 are in a triangle structure and have a clamping effect, so that in the process of integrally bending and arranging the artificial intelligence data transmission cable, the possibility of abnormal bending of the single coaxial cable 100 is reduced due to the clamping effect; since the size of the coaxial cable is generally larger than that of the twisted pair 200, the grooves formed on the outer sides of the adjacent coaxial cables 100 are larger, and when one twisted pair 200 is respectively arranged therein and the grooves are filled, the three twisted pairs 200 can be well fixed, and the twisted pairs 200 outside the three twisted pairs are not interfered by the grooves with larger sizes.
