Description

Technical Field

[0001] This utility model relates to the field of communication cable technology, and in particular to a high-speed communication cable. Background Technology

[0002] High-speed communication cables are cable types capable of supporting high-frequency signal transmission and meeting the demands of high-speed data communication. They are a crucial foundation for modern communication and information transmission, and their high bandwidth, low loss, and high anti-interference performance make them widely used in the internet, cloud computing, consumer electronics, 5G, and industrial fields. In the future, with the continuous growth of data transmission demands, high-speed communication cables will continue to develop towards higher performance, lighter weight, and greater intelligence. Specifically, high-speed communication cables possess characteristics such as high bandwidth, low signal attenuation, high anti-interference, excellent high-frequency characteristics, and strict impedance control. The low signal attenuation characteristic relies on the selection of high-quality conductors and insulation materials to reduce signal attenuation during long-distance transmission. For insulation materials, existing high-speed communication cables use fluorinated ethylene propylene copolymer (FEP) to wrap the conductor, followed by a layer of PTFE to ensure the cable's insulation and heat resistance.

[0003] Due to the high demands on heat resistance and insulation performance of high-speed communication cables, existing high-speed communication cables still largely use PTFE material as insulation to cover conductors. However, current medical research has found that fluorine-containing materials pose a risk of harm to the human body. Given the increasingly stringent market requirements for the non-toxicity of cables and other components, the aforementioned fluorine-containing high-speed communication cables clearly do not meet current market demands. Utility Model Content

[0004] Therefore, it is necessary to provide a high-speed communication cable that addresses the technical problem that the insulation materials of existing high-speed communication cables do not meet market demands.

[0005] A high-speed communication cable includes a conductor, an insulation layer, a shielding layer, and a Mylar layer. The conductor is configured as a linear structure with a preset size and a preset cross-sectional type. The insulation layer covers the side surface of the conductor along the extension direction of the conductor. The shielding layer covers the side surface of the insulation layer, and the Mylar layer covers the side surface of the shielding layer, thereby forming the basic structure of the high-speed communication cable.

[0006] High-speed communication cables also include a foamed tape layer, which is placed between the insulation layer and the shielding layer. That is, the inner surface of the foamed tape layer is bonded to the outer surface of the insulation layer, and the outer surface of the foamed tape layer is bonded to the inner surface of the shielding layer, thereby forming a porous structure between the insulation layer and the shielding layer.

[0007] In one embodiment, the aforementioned foamed tape layer is configured as a porous structure layer made of PP.

[0008] In one embodiment, the insulating layer described above is made of PP.

[0009] In one embodiment, the shielding layer described above is made of aluminum foil.

[0010] In one embodiment, the high-speed communication cable described above is provided with a plurality of conductors arranged in parallel within the insulation layer.

[0011] In one embodiment, each of the conductors described above is independently covered with an insulating layer.

[0012] In one embodiment, the aforementioned conductors, each independently covered with an insulating layer, are housed within the same foamed tape layer.

[0013] In one embodiment, the high-speed communication cable further includes at least one ground wire disposed on the adjacent side of a plurality of conductors.

[0014] In one embodiment, each of the above-mentioned ground wires is disposed between the shielding layer and the Mylar layer.

[0015] In one embodiment, the high-speed communication cable described above is provided with two conductors arranged in parallel.

[0016] In one embodiment, the distance between the two conductors is set to 0.47 ± 0.05 mm.

[0017] In one embodiment, the overall width of the high-speed communication cable is set to 1.15 ± 0.08 mm.

[0018] In one embodiment, the overall thickness of the high-speed communication cable is set to 0.71 ± 0.05 mm.

[0019] In one embodiment, the high-speed communication cable described above is provided with two ground wires, which are respectively arranged in parallel on the opposite sides of the two conductors.

[0020] In one embodiment, the overall width of the high-speed communication cable is set to 1.75 ± 0.10 mm.

[0021] In one embodiment, the overall thickness of the high-speed communication cable is set to 1.05 ± 0.08 mm.

[0022] In one embodiment, the aforementioned Mylar layer is further provided with a marking portion, which is disposed on the outer surface of the Mylar layer.

[0023] The aforementioned high-speed communication cable incorporates a foamed tape layer between the insulation and shielding layers. Specifically, the inner surface of the foamed tape layer is bonded to the outer surface of the insulation layer, and the outer surface of the foamed tape layer is bonded to the inner surface of the shielding layer. This creates a porous structure between the insulation and shielding layers, allowing sufficient air to fill the space. This reduces the dielectric constant of the outer layer of the high-speed communication cable while providing thermal insulation. Furthermore, the porous structure of the foamed tape layer effectively increases the specific surface area of ​​the material, accelerating heat dissipation and providing expansion space at high temperatures. This reduces stress caused by thermal expansion, thereby extending the cable's lifespan. Compared to traditional communication cables, this high-speed communication cable utilizes a porous foamed tape layer to ensure both insulation and heat resistance, effectively reducing the use of fluorinated heat-resistant materials. This approach maintains product performance while reducing toxicity and improving environmental friendliness to meet broader market demands. Attached Figure Description

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] Please see Figures 1 to 2This utility model discloses a high-speed communication cable 10, which includes a conductor 100, an insulation layer 200, a shielding layer 300, and a Mylar layer 400. The conductor 100 is configured as a linear structure with a preset size and a preset cross-sectional type. The insulation layer 200 covers the side surface of the conductor 100 along the extension direction of the conductor 100. The shielding layer 300 covers the side surface of the insulation layer 200, and the Mylar layer 400 covers the side surface of the shielding layer 300, thereby forming the basic structure of the high-speed communication cable 10. Specifically, the high-speed communication cable 10 also includes a foamed tape layer 500, which is disposed between the insulation layer 200 and the shielding layer 300. That is, the inner surface of the foamed tape layer 500 is bonded to the outer surface of the insulation layer 200, and the outer surface of the foamed tape layer 500 is bonded to the inner surface of the shielding layer 300. This forms a porous structure between the insulation layer 200 and the shielding layer 300, allowing sufficient air to be filled between them. This reduces the dielectric constant of the outer layer structure of the high-speed communication cable 10 while achieving thermal insulation. Furthermore, the porous structure of the foamed tape layer 500 effectively increases the specific surface area of ​​the material, accelerating heat dissipation and providing expansion space at high temperatures. This reduces the stress caused by the thermal expansion of the cable, thereby extending the cable's service life. Compared to traditional communication cables, the high-speed communication cable 10 of this invention uses a porous foamed tape layer 500 to ensure the insulation and heat resistance of the cable, thereby effectively reducing the use of fluorine-containing heat-resistant materials. This ensures product performance while reducing the toxicity of the cable and improving its environmental friendliness to meet more market demands.

[0033] Furthermore, the foamed tape layer 500 is set as a porous structure layer made of PP. PP has the characteristics of being lightweight and having excellent chemical resistance, electrical properties, and economy. Based on this, it can ensure good mechanical strength, toughness, insulation performance and durability while strengthening the lightweight design of the high-speed communication cable 10. At the same time, PP has good heat resistance and low toxicity, thereby further optimizing the environmental and human-friendly nature of the high-speed communication cable 10.

[0034] Furthermore, the insulating layer 200 is made of PP. PP has a high volume resistivity, which can provide excellent insulation effect and reduce the risk of current leakage. The insulating layer 200 made of PP can effectively guarantee the insulation performance of the conductor 100 to prevent signal leakage and open circuit between conductors 100.

[0035] Furthermore, the shielding layer 300 is made of aluminum foil, which is a highly efficient shielding material that can effectively shield external electromagnetic waves and radio frequency interference, protecting the integrity of the signals inside the cable. At the same time, the aluminum foil shielding layer 300 can effectively prevent the electromagnetic field of the signal inside the cable from leaking outward. By shielding external interference and reducing losses, the aluminum foil shielding layer 300 can improve the stability and efficiency of cable signal transmission.

[0036] Furthermore, the high-speed communication cable 10 is provided with a plurality of conductors 100, which are arranged in parallel within the insulation layer 200 to meet the requirements of high-speed, multi-signal, high anti-interference, and high-reliability transmission of the high-speed communication cable 10. Specifically, each conductor 100 is independently covered with an insulation layer 200 to ensure the insulation performance between adjacent conductors 100, reduce signal interference between conductors 100, and prevent short circuits. More specifically, the plurality of conductors 100, each independently covered with an insulation layer 200, are housed within the same foam tape layer 500 to control the overall size of the high-speed communication cable 10, thereby ensuring the practicality of the high-speed communication cable 10.

[0037] Furthermore, the high-speed communication cable 10 also includes at least one ground wire 600, which is disposed adjacent to several conductors 100 to ensure the electrical safety, operational stability, and anti-interference capability of the high-speed communication cable 10. Specifically, each ground wire 600 is disposed between the shielding layer 300 and the Mylar layer 400 to ensure that the ground wire 600 provides effective electrical grounding, optimizes the shielding performance of the high-speed communication cable 10, and prevents direct contact between the ground wire 600 and the conductors 100, thereby avoiding short circuits or interference.

[0038] In one embodiment, the high-speed communication cable 10 has two parallel conductors 100. In this embodiment, the distance between the two conductors 100 is set to 0.47±0.05mm. In this embodiment, the overall width of the high-speed communication cable 10 is set to 1.15±0.08mm. In this embodiment, the overall thickness of the high-speed communication cable 10 is set to 0.71±0.05mm.

[0039] In another embodiment, the high-speed communication cable 10 is provided with two ground wires 600, which are respectively arranged parallel to each other on the opposite sides of the two conductors 100. In this embodiment, the overall width of the high-speed communication cable 10 is set to 1.75±0.10mm. In this embodiment, the overall thickness of the high-speed communication cable 10 is set to 1.05±0.08mm.

[0040] Furthermore, the Mylar layer 400 is also provided with a marking section 410, which is located on the outer surface of the Mylar layer 400. In actual production, the marking section 410 is used to print markings to achieve identification and differentiation between high-speed communication cables 10 of different specifications.

[0041] In summary, the high-speed communication cable disclosed in this invention forms a porous structure between the insulation layer and the shielding layer by placing a foamed tape layer between them. Specifically, the inner surface of the foamed tape layer is bonded to the outer surface of the insulation layer, and the outer surface of the foamed tape layer is bonded to the inner surface of the shielding layer. This creates a porous structure that allows sufficient air to fill the space between the insulation and shielding layers. This reduces the dielectric constant of the outer layer of the high-speed communication cable while providing thermal insulation. Furthermore, the porous structure of the foamed tape layer effectively increases the specific surface area of ​​the material, accelerating heat dissipation and providing expansion space at high temperatures. This reduces stress caused by thermal expansion, thereby extending the cable's service life. Compared to traditional communication cables, this high-speed communication cable uses a porous foamed tape layer to ensure both insulation and heat resistance, effectively reducing the use of fluorinated heat-resistant materials. This ensures product performance while reducing toxicity and improving environmental friendliness to meet broader market demands.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
