[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0016] See also Figure 1 In an embodiment of the utility model, an integrated image transmission and signal control composite line includes a filling strip 1, which is made of aramid with high tensile strength. A plurality of first coaxial lines 2 are evenly distributed on the outside of the filling strip 1. The filling strip 1 and the plurality of first coaxial lines 2 are wrapped by a first wrapping tape 5. A plurality of second coaxial lines 3 are evenly distributed on the outside of the first wrapping tape 5. The outer sides of the plurality of second coaxial lines 3 are wrapped by a second wrapping tape 6. The outer side of the second wrapping tape 6 is wrapped with a braided layer 4, and the braided layer 4 is a copper wire braided layer. The outer side of the braided layer 4 is wrapped with a third wrapping tape 7. The first wrapping tape 5, the second wrapping tape 6 and the third wrapping tape 7 are all wrapped with ePTFE tapes.

[0017] A total of 36 first coaxial lines 2 are provided, and a total of 38 second coaxial lines 3 are provided; the first coaxial line 2 adopts a 28AWG single insulated core wire for signal control; the second coaxial line 3 adopts a 34AWG video signal transmission coaxial line; the second coaxial line 3 includes a conductor, an insulating layer, a shielding layer, and an outer sheath, the outer side of the conductor is coated with an insulating layer, the outer side of the insulating layer is coated with a shielding layer, and the outer side of the shielding layer is coated with an outer sheath.

[0018] A multi-unit combination of 38 36AWG coaxial wires and 36 28AWG single-insulated core wires is used; each unit conductor has small specifications and dimensions, and the outer sheath material is changed from traditional plastic extrusion to special ePTFE tape wrapping, which effectively reduces the size of the finished product; due to the large total number of coaxial wires and single-insulated wires, cabling equipment with small pay-off tension and large pay-off quantity is required.

[0019] To address the problem of twisting of a single wire inside after repeated movement of similar wires, this solution has designed multiple layered assemblies, different twisting pitches and twisting directions, and 100% detwisting of all core wires, effectively avoiding this problem.

[0020] To address the problem of poor tensile resistance, this solution fills the center of the cable with high-strength aramid fiber, and keeps the aramid fiber in a straight form when the remaining core wire units are twisted. In this way, when the cable is pulled, the aramid fiber bears the tension, thereby protecting the other core wire units.

[0021] The entire cable has a round appearance and a distinct structural layering, which makes it convenient for customers to group and identify each unit by layer during processing, reducing the risk of assembly errors.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
