Description

Technical Field

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

[0002] In modern industry, communications, and energy transmission, cables serve as crucial transmission media, and their performance directly impacts the stability and reliability of system operation. Traditional cables, to ensure mechanical strength, often use steel or other metal materials as reinforcement layers. While this can withstand certain external forces, it significantly increases the overall weight of the cable, increasing installation difficulty, transportation and maintenance costs, and limiting its application in special environments such as high altitudes and deep seas. Furthermore, with the increasing integration of electronic devices and the rising frequency of signal transmission, external electromagnetic interference easily causes signal attenuation and distortion, and traditional cable shielding designs struggle to meet the signal integrity requirements of complex electromagnetic environments. Simultaneously, extreme environments such as high temperatures, humidity, and corrosion place even higher demands on the environmental resistance of cables. Utility Model Content

This cable solves the problems that existing cables may have during use, such as signal interference, excessive weight, insufficient mechanical strength, and poor environmental adaptability. It is especially suitable for application scenarios that require weight reduction, improved durability, and tensile strength.

[0004] This utility model also provides a lightweight, high-strength communication cable comprising: a conductor assembly, an insulation layer, a shielding layer, a reinforcement layer, and an outer protective layer. The conductor assembly is composed of silver-clad copper wires with a diameter of 0.5 mm, and the conductor assembly is a multi-core structure composed of several silver-clad copper wires. The shielding layer consists of an inner shielding layer and an outer shielding layer. The inner shielding layer is made of silver-plated polyester film, and the outer shielding layer is made of braided nickel-clad aluminum mesh. The reinforcement layer consists of a first reinforcement layer and a second reinforcement layer. The first reinforcement layer is made of Kevlar fiber braid, and the second reinforcement layer is made of a high-performance polymer. This cable enhances its overall transmission capacity, meeting the needs of complex systems or multi-channel communication, while also increasing the overall mechanical strength of the cable, making it more resistant to tension, bending, and external mechanical stress, extending its service life, and reducing the overall weight of the cable.

[0005] According to this utility model, a lightweight, high-strength communication cable is provided, wherein the insulation layer is fixedly connected to the conductor assembly, the insulation layer is made of high-performance polyimide material, and the insulation layer is configured with a multi-layer structure. This serves to reduce the overall weight of the cable and also prevents the conductor from contacting the outside environment, thus avoiding signal leakage or short circuits.

[0006] According to the present invention, a lightweight high-strength communication cable is provided, wherein the inner shielding layer is fixedly connected to the insulation layer, and the outer shielding layer is wound around the outer surface of the inner shielding layer. This serves to ensure a strong connection between the two and form a continuous shield.

[0007] According to the present invention, a lightweight high-strength communication cable is provided, wherein the outer surface of the outer layer of the shielding layer is fixedly connected to the first reinforcing layer, and the second reinforcing layer covers the outer surface of the first reinforcing layer and is fixedly connected thereto. This forms the supporting structure for the entire cable.

[0008] According to the present invention, a lightweight high-strength communication cable is provided, wherein the outer protective layer is made of silicone rubber and the thickness of the outer protective layer is set to 1-2 mm. This provides sealing, anti-fouling, and anti-corrosion functions for the entire cable.

This ensures the overall environmental resistance of the cable.

[0010] According to the present invention, a lightweight high-strength communication cable comprises a conductor assembly, an insulation layer, a shielding layer, a reinforcing layer, and an outer protective layer connected sequentially from the inside out. This forms a complete, lightweight, high-strength cable assembly.

[0011] According to the present invention, a lightweight high-strength communication cable has an insulation layer thickness of at least 0.2 mm and a reinforcing layer thickness of at least 0.5 mm. This significantly increases the overall tensile, tear, and bending resistance of the cable, extending its service life.

[0012] Beneficial effects:

[0013] This lightweight, high-strength communication cable utilizes a conductor assembly, insulation layer, shielding layer, reinforcement layer, and outer protective layer connected sequentially from the inside out. This significantly enhances the cable's mechanical strength while reducing its overall weight. Compared to traditional steel or metal reinforcement layers, it is lightweight yet high-strength, further reducing the overall cable weight and facilitating installation and maintenance. The reinforcement layer combines high-strength braided Kevlar fibers with high-performance polymers, significantly improving the cable's mechanical properties and weight-to-weight ratio, providing a double shielding effect and ensuring signal integrity and interference resistance. Furthermore, the rational combination of multiple layers enhances environmental resistance and overall stability. Attached Figure Description

The outer shielding layer 31 is made of braided nickel-clad aluminum mesh and serves as the second layer of shielding, enhancing signal anti-interference capabilities and providing mechanical protection. The reinforcement layer consists of reinforcement layer 4 and reinforcement layer 41. Reinforcement layer 4 is made of Kevlar fiber braid, which provides extremely high tensile strength and tear resistance through its braided structure, preventing the cable from being pulled apart or damaged by entanglement. Reinforcement layer 41 is made of high-performance polymer, which provides the cable with additional mechanical barriers and weather resistance, while reducing the overall weight of the cable.

[0023] Specifically, the insulation layer 2 is fixedly connected to the conductor assembly 1.

The inner shielding layer 3 is fixedly connected to the insulation layer 2. The outer shielding layer 31 is wrapped around the outer surface of the inner shielding layer 3 to ensure the connection between the two and form a continuous shield. The outer surface of the outer shielding layer 31 is fixedly connected to the first reinforcement layer 4. The second reinforcement layer 41 covers the outer surface of the first reinforcement layer 4 and is fixedly connected to form the support structure of the entire cable, ensuring that the internal conductor and shielding layer remain intact under tension, bending or external force. The outer protective layer 5 is made of silicone rubber, with a thickness of 1-2 mm. Utilizing its excellent UV resistance, water resistance, and abrasion resistance, it provides sealing, anti-fouling, and anti-corrosion protection for the cable. The outer protective layer 5 is fixedly connected to the reinforcing layer 41, located on the outer surface of the reinforcing layer. An adhesive bonded between the outer protective layer 5 and the reinforcing layer ensures the overall environmental resistance.
