Description

Technical Field

[0001] This utility model relates to the field of composite cable technology, and in particular to a flame-retardant composite cable for computers. Background Technology

[0002] With the rapid development of computer technology, the performance requirements for cables are also increasing. On the one hand, computer equipment generates a lot of heat during operation, and the surrounding environment may contain fire sources and other safety hazards. Ordinary cables are easily ignited at high temperatures or when exposed to fire, which can not only damage equipment but also cause fires, resulting in serious property damage and personal injury. Therefore, flame retardant performance has become one of the key indicators for composite cables used in computers.

[0003] On the other hand, computer systems have extremely high requirements for the quality and stability of signal transmission; any interference can lead to data loss or errors. Traditional cables are insufficient in their anti-interference capabilities and cannot meet the signal shielding requirements of modern computer systems.

[0004] Furthermore, composite cables for computers also need to possess good mechanical properties in practical applications to adapt to complex installation environments and usage conditions. For example, during the wiring process, they may be subjected to external forces such as pulling and bending. If the cable's strength and flexibility are insufficient, it is prone to damage, affecting its service life. Utility Model Content

[0005] To address some of the problems existing in the prior art, this utility model provides a flame-retardant composite cable for computers. This utility model significantly improves the performance of the composite cable for computers by optimizing the structure of each layer and selecting high-performance materials. The flame-retardant filler layer uses modified low-smoke halogen-free flame-retardant polyolefin material with embedded flexible reinforcing ribs to enhance flame retardancy; the outer shielding layer uses two layers of tinned copper wire with different braiding angles and a decreasing braiding density gradient to improve electromagnetic shielding effect; the outer insulation layer uses cross-linked polyethylene with nano-additives, and the outer sheath layer uses flame-retardant polyvinyl chloride material filled with fibers to improve insulation and durability.

[0006] To achieve the above objectives, this utility model provides a flame-retardant composite cable for computers, comprising a composite cable body. The composite cable body includes a conductor layer disposed at the center of the composite cable body. An outer insulation layer, a flame-retardant filling layer, an outer shielding layer, and an outer sheath layer are sequentially disposed outside the conductor layer. The outer insulation layer tightly covers the outer surface of the conductor core layer. The flame-retardant filling layer fills the space between the outer insulation layer and the outer shielding layer. The outer shielding layer tightly covers the outer surface of the flame-retardant filling layer.

[0007] As a further improvement of this utility model, in order to effectively isolate each conductor core wire and prevent mutual short circuits, the conductor layer is provided with several groups of conductor core wires, which are made of multiple strands of ultra-fine copper conductors twisted together. An insulating isolation layer is provided on the outside of the conductor core wires, and the surface of the insulating isolation layer is coated with a nano-ceramic coating.

[0008] As a further improvement of this utility model, in order to effectively separate different signal lines, reduce interference between signals, improve the quality and stability of signal transmission, and ensure smooth communication between various parts of the computer system, a signal cable group is arranged around the conductor layer. The signal cable group includes a single-core signal line and a double-core reinforced signal line that cooperates with the single-core signal line. A separating insulation layer is provided between the single-core signal line and the double-core reinforced signal line.

[0009] As a further improvement of this utility model, in order to make the cable less susceptible to damage under bending, stretching and other conditions and extend the service life of the cable, the flame-retardant filler layer is made of modified low-smoke halogen-free flame-retardant polyolefin material. The flame-retardant filler layer is embedded with a number of flexible reinforcing ribs distributed along the cable axis. The reinforcing ribs are made of aramid fiber and have a diameter of 0.15mm-0.35mm.

[0010] As a further improvement of this utility model, in order to further improve the insulation performance, aging resistance and heat resistance of the cable, so that the cable can still maintain a good insulation state under harsh environments such as high temperature and high voltage, the outer insulation layer tightly covers the conductor core layer and is composed of cross-linked polyethylene insulation material. The interior of the outer insulation layer is uniformly distributed with nano-level insulation additives.

[0011] As a further improvement of this utility model, in order to improve the flexibility and adaptability of the shielding layer and enable the cable to maintain good shielding performance when bent, the outer shielding layer is made of at least two layers of tinned copper wire with different braiding angles. The braiding density of the outer shielding layer decreases gradually from the inside to the outside. The braiding angle of the inner layer of the outer shielding layer is 35°-50°, and the braiding angle of the outer layer of the outer shielding layer is 40°-60°.

[0012] As a further improvement of this utility model, in order to further improve the flame retardant performance of the outer sheath and enhance the fire resistance of the cable, the outer sheath is made of polyvinyl chloride flame retardant material, the interior of the outer sheath is filled with flame retardant fibers, and the outer surface of the outer sheath is provided with anti-slip protrusions, the protrusions being hemispherical in shape.

[0013] When this invention is in operation, as current passes through the conductor layer, the conductor core, composed of multiple strands of ultra-fine copper conductors twisted together, efficiently transmits electrical energy due to its excellent conductivity. The insulating layer and nano-ceramic coating on the outside of the conductor core effectively prevent current leakage, ensuring electrical safety. Simultaneously, the nano-ceramic coating also resists environmental corrosion of the conductor core.

[0014] The signal cable group surrounding the conductor layer is responsible for transmitting various signals in the computer system. Single-core signal lines and dual-core reinforced signal lines, protected by the separating insulation layer, work independently yet collaboratively to reduce interference between signals, ensure the accuracy and stability of signal transmission, and enable efficient communication between various computer components.

[0015] The outer insulation layer uses cross-linked polyethylene insulation material with added nano-level insulation additives to provide reliable insulation protection for the conductor layer and signal cable assembly. Even in harsh environments such as high temperature and high voltage, it can maintain good insulation performance and prevent faults such as short circuits.

[0016] The flame-retardant filler layer is made of modified low-smoke halogen-free flame-retardant polyolefin material, and the embedded aramid fiber flexible reinforcement enhances the cable's tensile strength and flexibility. In the event of an emergency such as a fire, the flame-retardant filler layer can effectively prevent the spread of fire and reduce harm to the environment and human health.

[0017] The outer shielding layer adopts a multi-layered structure of tinned copper wire with different braiding angles and a decreasing braiding density gradient, which can effectively shield external electromagnetic interference and prevent the leakage of the cable's own electromagnetic signals, ensuring that signal transmission is not affected by external factors.

[0018] The outer sheath is made of flame-retardant polyvinyl chloride material and filled with flame-retardant fibers, further enhancing the cable's flame-retardant performance. The hemispherical anti-slip protrusions on its outer surface increase the friction between the cable and the mounting surface, facilitating installation and fixing, preventing cable slippage and displacement, and ensuring stable and reliable operation of the cable in various working environments.

[0019] The beneficial effects of this utility model are as follows: Regarding the conductor layer: The conductor layer contains several sets of conductor cores made of multiple strands of ultra-fine copper conductors twisted together, which increases the flexibility and conductivity of the conductor. At the same time, an insulating layer is set on the outside of the conductor cores, and a nano-ceramic coating is applied to the surface of the insulating layer to enhance the insulation performance and high temperature resistance of the conductor cores, which helps to improve the electrical performance and service life of the cable.

[0020] The conductor layer is surrounded by a signal cable assembly, including single-core signal lines and dual-core reinforced signal lines, and is equipped with a separating insulation layer. This enables effective signal transmission, and the separating insulation layer avoids interference between signals, improving the accuracy and stability of signal transmission. It is suitable for equipment such as computers that have high requirements for signal transmission.

[0021] Regarding the flame-retardant filler layer: The flame-retardant filler layer is composed of modified low-smoke halogen-free flame-retardant polyolefin material, which has excellent flame-retardant properties and can effectively prevent the spread of fire and reduce the generation of smoke and toxic gases in the event of a fire. Embedded with several flexible aramid fiber reinforcing ribs distributed along the cable axis, it enhances the cable's tensile strength and flexibility, and improves the cable's mechanical properties.

[0022] Regarding the external insulation layer: The external insulation layer is composed of cross-linked polyethylene insulation material, which has excellent insulation properties and can effectively prevent current leakage, ensuring the safe operation of the cable. Uniformly distributed nano-level insulation additives further enhance the insulation performance, improving the electrical stability and reliability of the cable.

[0023] Regarding the external shielding layer: The external shielding layer is composed of at least two layers of tinned copper wire with different braiding angles, and the braiding density gradually decreases from the inside to the outside. This design can effectively shield external electromagnetic interference and ensure stable signal transmission inside the cable. The design of different braiding angles and gradually decreasing braiding density allows the shielding layer to exert a good shielding effect in different directions, improving the cable's anti-interference capability.

[0024] Regarding the outer sheath: The outer sheath is made of flame-retardant polyvinyl chloride material, filled with flame-retardant fibers, further enhancing the cable's flame-retardant performance. The outer surface features hemispherical anti-slip protrusions, which not only increase the cable's friction, facilitating installation and fixation, but also protect the cable surface from wear to a certain extent, extending the cable's service life.
