Description

Technical Field

[0001] This utility model relates to the field of data transmission line technology, specifically to a high-frequency cable with a flat-coated inner sheath process. Background Technology

[0002] With the rapid promotion and widespread application of advanced technologies such as big data, cloud computing, and 5G, human society is entering an era of information explosion. In this era, data transmission speed has become one of the key indicators for measuring the level of information technology development. Whether it's big data analysis, cloud computing services, or the construction of 5G communication networks, all rely on efficient and stable data transmission support. Therefore, the demand for data transmission speed has also increased dramatically, and traditional data transmission lines can no longer meet the needs of modern information technology.

[0003] Existing standard Mylar signal cables with aluminum foil have played a vital role in traditional data transmission. However, in high-speed data transmission scenarios, these cables have revealed some significant problems. Particularly at high frequencies, the signal is prone to "dropping," where the signal suddenly weakens or is lost during transmission, severely impacting the integrity and stability of data transmission. This phenomenon not only reduces data transmission speed but also increases the error rate, posing a significant challenge to applications such as big data processing, cloud computing services, and 5G communications.

[0004] With the continuous development of technologies such as big data, cloud computing, and 5G, the demand for data transmission speeds is increasing. Traditional ordinary aluminum foil-wrapped Mylar signal cables can no longer meet the needs of modern information technology, necessitating continuous exploration and research into new data transmission cable materials and structures. By optimizing design and adopting new materials and processes, we can effectively improve the transmission speed and stability of data transmission cables, providing more efficient and reliable data transmission support for applications such as big data processing, cloud computing services, and 5G communications. Utility Model Content

[0005] Therefore, the purpose of this application is to solve the technical problem of high-frequency drop-off in signal transmission lines in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-frequency cable with a flat-coated inner sheath includes a core wire, a first Mylar layer, and a wrapping layer arranged sequentially from the inside out. The core wire is formed by extrusion. The first Mylar layer is used to fix the core wire. An inner sheath is provided between the first Mylar layer and the wrapping layer. The inner sheath is formed by extrusion. The wrapping layer is wrapped around the outer periphery of the first Mylar layer.

[0008] Preferably, the outer periphery of the wrapping layer is wrapped with a second Mylar layer, which is used to fix and protect the wrapping layer.

[0009] Preferably, at least two sets of core wires are provided, and the core wires are arranged in a twisted manner.

[0010] Preferably, the conductor is a copper conductor, and the insulating layer is tightly wrapped around the conductor by an extrusion process.

[0011] Preferably, the insulating layer is a polyethylene insulating layer.

[0012] Preferably, the wrapping layer covers the outer periphery of the inner layer, and the wrapping layer is an aluminum foil wrapping layer.

[0013] Preferably, the first Mylar layer is tightly bonded to the outside of the core wire.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] 1. The high-frequency cable provided in this application achieves efficient and stable signal transmission through a carefully designed multi-layer structure. The core wire uses copper conductors, which, due to their excellent conductivity, especially their low resistivity, ensure high efficiency and high quality during signal transmission. This characteristic makes the cable particularly suitable for applications requiring high-speed, high-quality signal transmission, such as data centers, communication equipment, and audio / video transmission systems.

[0016] 2. The inclusion of the first Mylar layer and the middle sheath not only stabilizes the cable structure and prevents the core wires from loosening, but more importantly, it solves the dielectric constant problem during signal transmission. This means that the signal will not experience unnecessary attenuation or distortion due to changes in the medium during transmission, thereby further improving the high-frequency transmission performance of the cable.

[0017] 3. The inclusion of a wrapping layer and a second Mylar layer further enhances the cable's shielding effectiveness and structural stability. Aluminum foil, as a conventional shielding material, possesses excellent conductivity and shielding properties, effectively isolating external electromagnetic interference and protecting the internal signals of the cable from interference. Simultaneously, the second Mylar layer further secures and protects the wrapping layer, ensuring the cable maintains its structural integrity during use and preventing loosening or damage. This design allows the cable to better adapt to various complex operating environments, improving its durability and reliability. Attached Figure Description

[0018] Figure 1 This is a schematic cross-sectional view of a high-frequency cable using a flat-wrapping process according to one embodiment of the present invention.

[0019] In the diagram, 1 is the core wire; 11 is the conductor; 12 is the insulation layer; 2 is the first Mylar layer; 3 is the middle sheath layer; 4 is the wrapping tape layer; and 5 is the second Mylar layer. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 A high-frequency cable with a flat-coated inner sheathing process includes, from the inside out, a core wire 1, a first Mylar layer 2, an inner sheathing layer 3, a wrapping layer 4, and a second Mylar layer 5.

[0022] Please see Figure 1 In one embodiment, at least two sets of core wires 1 are provided, and the two sets of core wires 1 are arranged in a twisted manner. Each core wire 1 includes a conductor 11 and an insulation layer 12 tightly covering its outer periphery. In one embodiment, the conductor 11 is a copper conductor 11, because the copper conductor 11 has excellent conductivity, especially low resistivity, which is crucial for ensuring high efficiency and high quality of signal transmission. In addition, the copper conductor 11 also has advantages such as low cost and easy installation, and has a long history and wide application in the cable manufacturing field. It serves as the transmission medium for computer peripheral cables, using the current transmitted in the medium as the carrier of data signals.

[0023] The insulation layer 12 is a polyethylene insulation layer 12, and it is tightly wrapped around the conductor 11 through an extrusion process. The polyethylene insulation layer 12 has a series of excellent electrical properties, such as low insulation resistance and stable capacitance. These characteristics are crucial for ensuring accurate and lossless transmission of high-frequency signals. At the same time, polyethylene material also has good mechanical strength and aging resistance, which can ensure that the cable maintains stable electrical performance and physical structure during long-term use.

[0024] Please see Figure 1 The first Mylar layer 2 is used to fix the core wire 1. In one embodiment, after the core wire 1 undergoes an extrusion process, the first Mylar layer 2 is tightly adhered to the outside of the core wire 1, playing a key role in stabilizing the structure and preventing the core wire 1 from loosening. Mylar is a high-strength, high-transparency polyester film with excellent insulation and weather resistance, and is a commonly used fixing and protective material in cable manufacturing.

[0025] Please see Figure 1 The intermediate layer 3 is sleeved on the first Mylar layer 2. The intermediate layer 3 is extruded and its main function is to solve the dielectric constant problem during signal transmission, that is, to ensure that the signal will not experience unnecessary attenuation or distortion due to changes in the medium during transmission. The design of this layer is of decisive significance for improving the high-frequency transmission performance of the cable.

[0026] Please see Figure 1 The wrapping layer 4 covers the outer periphery of the inner sheath 3. In one embodiment, the wrapping layer 4 is an aluminum foil wrapping layer 4. Aluminum foil is a conventional shielding material with excellent conductivity and shielding effect. The aluminum foil wrapping layer 4 not only effectively isolates external electromagnetic interference and protects the internal signals of the cable from being affected, but also enhances the overall structural stability of the cable, preventing deformation or damage under bending, pulling, and other usage scenarios.

[0027] The second Mylar layer 5 is located on the outer periphery of the wrapping layer 4. Its main function is to further fix and protect the wrapping layer 4, ensuring that the cable maintains its structural integrity during use and preventing loosening or damage. The presence of the second Mylar layer 5 provides an additional protective layer for the cable, enabling it to better adapt to various complex operating environments.

[0028] In summary, the high-frequency cable with a flat-coated inner sheath provided in this application achieves efficient and stable signal transmission through a carefully designed multi-layer structure. The core wire 1 uses a copper conductor 11 and a polyethylene insulation layer 12 to ensure accurate signal transmission; the first Mylar layer 2 and the inner sheath layer 3 solve the dielectric constant problem in signal transmission, improving the cable's high-frequency performance; the addition of the aluminum foil wrapping layer 4 and the second Mylar layer 5 further enhances the cable's shielding effect and structural stability. This series of designs makes this high-frequency cable excellent in reducing attenuation loss and improving transmission efficiency, making it particularly suitable for applications requiring high-speed, high-quality signal transmission, such as data centers, communication equipment, and audio / video transmission systems. Furthermore, the cable also possesses good flexibility and durability, facilitating installation and maintenance, and providing strong support for the construction and development of modern electronic communication systems.
