However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0017] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or a middle element can exist simultaneously. In contrast, when an element is referred to as being "directly" connected to another element, no intermediate element exists.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0019] As Figure 1 , Figure 2As shown, a data cable of halogen-free material includes at least one conductor 1, a first insulating layer 2, a second insulating layer 3, at least one ground wire 4, at least one shielding layer 5, and a protective layer 6. The conductor 1 is wrapped by the first insulating layer 2, the first insulating layer 2 is wrapped by the second insulating layer 3, the second insulating layer 3 is wrapped by the shielding layer 5, the shielding layer 5 is wrapped by the protective layer 6, and the ground wire 4 is installed between the shielding layer 5 and the protective layer 6. The first insulating layer 6 is made of PMP material.

[0020] The conductor 1 can be one or two. Two conductors 1 are symmetrically arranged in the first insulating layer 2. The distance between the center points of the two conductors 1 is 2.08 mm,

[0021] The ground wire 4 can be one or two. Two ground wires 4 are symmetrically arranged between the shielding layer 5 and the protective layer 6.

[0022] The distance between the two ends of the first insulating layer 2 is 4.8 mm. The first insulating layer 6 is made of PMP material, which is called poly-4-methyl-pentene-1, and the chemical name is Methyl pentene copolymer, which is abbreviated as PMP. PMP is a polymer of 4-methyl-pentene-1 produced by Mitsubishi Chemical Corporation, Japan, and the trade name is TPX. PMP is a high-crystalline transparent plastic with a specific gravity of 0.83, which is the lightest among all plastics, and has excellent heat resistance, transparency and electrical insulation.

[0023] PMP material has good heat resistance, PMP can still be used for 100 hours above 150℃, and can be used for 100 hours in an environment of 180℃, which can ensure the service life of the data cable. Moreover, the light transmittance reaches 90%~92%, which is the only crystalline polymer in commercial high-transparency resin. It has good electrical insulation: dielectric strength is 65KV / mm, and dielectric constant is 2.12. It can effectively avoid the occurrence of short circuit problem of data cable in use. It has good chemical resistance: resistant to acid, alkali and organic solvents, avoiding corrosion of data cable during long-term use, and low water absorption. Moreover, it is non-toxic, in line with the U.S. FDA, and can be used for food contact. PMP (poly-4-methyl-1-pentene) is a plastic containing only C and H elements, so it does not contain halogen, and is more environmentally friendly.

[0024] In one embodiment, the second insulating layer 3 is made of polytetrafluoroethylene material.

[0025] Thus, the second insulation layer 3 is made of polytetrafluoroethylene material, and the excellent electrical insulation performance of polytetrafluoroethylene makes it an ideal material in the electronics industry. It can be used to produce the insulation layer of the wire and cable, and also can be used to manufacture electronic components such as capacitors, transformers, etc. PTEE is a polymer polymerized with tetrafluoroethylene as a monomer, with the chemical formula (C2F4)n, which has excellent heat and cold resistance and does not contain halogen, making the second insulation layer 3 made of polytetrafluoroethylene material more environmentally friendly.

[0026] In one embodiment, the shielding layer includes one of aluminum foil material or copper foil material or copper aluminum graphene composite material.

[0027] Thus, by the setting of the shielding layer 5, the aluminum foil material or the copper foil material or the copper aluminum graphene composite material can be used as the shielding material of the cable, reducing electromagnetic interference and noise, and improving the stability and reliability of signal transmission. In addition, the cable aluminum foil can also be used as the cable insulation material to shield the interference of external electric field and electromagnetic wave, and protect the signals inside the cable from external noise interference. The cable aluminum foil material itself usually does not contain halogen, and the aluminum foil is mainly used for the shielding layer of the cable, which plays a role in preventing electromagnetic interference and protecting the signal transmission inside the cable.

[0028] In one embodiment, the protective layer 6 is made of hot melt PET material.

[0029] Thus, hot melt PET has good electrical insulation performance, which can effectively isolate the wire and cable, prevent current leakage and short circuit, and ensure the safe operation of the wire;

[0030] ‌Hot melt PET has excellent anti-friction performance and ultraviolet resistance, which can protect the data line from damage by external environment and prolong the service life of the cable. At the same time, hot melt PET can withstand high temperature environment and is suitable for use in high temperature conditions, ensuring the stable operation of the cable in harsh environment. Hot melt PET does not contain halogen, making it more environmentally friendly.

[0031] Thus, the halogen-free data line is set by at least one conductor 1, first insulation layer 2, second insulation layer 3, at least one ground wire 4, at least one shielding layer 5 and protective layer 6, the first insulation layer 2 is made of PMP material, the second insulation layer 3 is made of polytetrafluoroethylene material, the shielding layer 5 is made of aluminum foil material, and the protective layer 6 is made of hot melt PET material. PMP material, polytetrafluoroethylene material, aluminum foil material and hot melt PET material are all halogen-free materials, which can effectively avoid the adverse effects on the environment and human health caused by the halogen in the data line, avoid environmental pollution, and ensure the health of the human body.

[0032] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
