Description

Technical Field

[0001] This utility model relates to the field of computer power cord technology, and in particular to a computer power cord with high tensile strength. Background Technology

[0002] With the rapid development and widespread application of information technology, computers have become an indispensable tool in modern society. As an important component for connecting computers to power, the performance of power cords directly affects the normal use and safety of computers. However, during the use of power cords, they are often subjected to external pressure, pulling, or need to be moved constantly. These situations can easily lead to the power cords being twisted, tangled, or damaged, thereby affecting the lifespan of the power cords and the stable operation of the computer.

[0003] A flexible, wear-resistant, and tensile-resistant power cord for mobile use, with publication number CN211699768U, belongs to the field of power cord technology. The power cord body contains several high-strength filler ropes and a conductor, with an insulation layer on the outside of the conductor. The high-strength filler ropes and conductor are wrapped with non-woven fabric, and a PVC sheath layer is placed outside the non-woven fabric. High-strength filaments are embedded inside the PVC sheath layer. This flexible, wear-resistant, and tensile-resistant power cord for mobile use has a simple and reasonable structure, and features flexibility, resistance to external tensile forces, torsion resistance, wear resistance, and a long service life, meeting the needs and safety requirements of reusable power supply for mobile devices.

[0004] The existing technology mentioned above only uses high-strength tensile wire to reinforce the power cord in terms of tensile strength. However, the method is relatively simple and the tensile strength is limited. Relying solely on this single method may not be able to cope with all complex stretching and torsion situations. When frequently bent, pulled, or subjected to external impact, the power cord may be damaged due to a lack of sufficient buffering and stress dispersion capabilities. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a computer power cord with high tensile strength, so as to solve the problem of poor tensile strength of existing computer power cords mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a computer power cord with high tensile strength, comprising a computer cord body and a tensile core, wherein the tensile core is provided inside the computer cord body;

[0007] The computer cable body is equipped with a tensile buffer component inside. The outside of the computer cable body is covered with a wear-resistant protective sleeve, and the wear-resistant protective sleeve is surrounded by a plurality of metal reinforcing wires in a circumferential array. The metal reinforcing wires are surrounded by a PVC protective sleeve, and the metal reinforcing wires inside the PVC protective sleeve are evenly filled with dense asbestos wires.

[0008] Preferably, the main body of the computer cable includes a conductor, an inner insulation layer, a high-temperature polyester tape shielding layer, and an outer insulation layer. There are three conductors, which are distributed around the tensile core. The outer side of each conductor is covered with an inner insulation layer, and the outer side of each conductor is covered with a high-temperature polyester tape shielding layer. An outer insulation layer is provided outside the high-temperature polyester tape shielding layer.

[0009] Preferably, the tensile core has a circular cross-section and is located at the center of the computer cable body. The tensile core is made of aramid fiber.

[0010] Preferably, the tensile buffer assembly includes tensile buffer columns evenly arranged inside the main body of the computer cable, and the tensile buffer columns are all made of rubber, with halogen-free low-smoke flame-retardant filler rope filling the gaps between the tensile buffer columns.

[0011] Preferably, the tensile buffer columns have circular cross-sections and are distributed in a ring around the conductor outside the inner insulation layer.

[0012] Preferably, multiple metal reinforcing wires are arranged around the wear-resistant protective sleeve in a ring shape, and the metal reinforcing wires are copper wires.

[0013] Preferably, the outer side of the PVC protective sleeve is coated with an anti-corrosion coating, and the anti-corrosion coating is a fluorocarbon resin coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This high-tensile-strength computer power cord has good tensile strength, making it less prone to breakage during use, thus ensuring the stability between the computer and the cord body. A tensile core made of aramid fiber is placed at the center of the cord body, possessing extremely high strength and toughness, effectively resisting tensile forces to improve the tensile performance of the cord body. Multiple rubber-made tensile buffer pillars are then placed around the conductor, exhibiting excellent elasticity and effectively absorbing and dispersing external impact forces, effectively protecting the conductor inside the cord body from damage. Furthermore, the multiple tensile buffer pillars create a stable support structure inside the cord body, resulting in even better tensile resistance.

[0016] Halogen-free, low-smoke, flame-retardant filler rope is tightly filled between the tensile buffer columns, which can enhance the overall strength and stability of the computer cable body. In addition, the halogen-free, low-smoke, flame-retardant filler rope has good flame-retardant properties, which can effectively prevent the spread of fire and improve the safety of the computer cable body.

[0017] The main body of the computer cable is covered with a wear-resistant protective sleeve, and multiple metal reinforcing wires are arranged in a ring around the wear-resistant protective sleeve. Dense asbestos fibers are filled in the gaps between the metal reinforcing wires. Then, a PVC protective sleeve is wrapped around the metal reinforcing wires to fix the position of the metal reinforcing wires and dense asbestos fibers, prevent the internal structure from deforming under stress, and help improve the strength and rigidity of the overall structure, preventing the main body of the computer cable from deforming when subjected to external pressure or impact.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figures 1-4The present invention provides an embodiment of a computer power cord with high tensile strength, comprising a computer cord body 1 and a tensile core 2. The tensile core 2 is provided inside the computer cord body 1. The tensile core 2 has a circular cross-section and is distributed at the center of the computer cord body 1. The tensile core 2 is made of aramid fiber.

[0026] The main body 1 of the computer cable includes a conductor 101, an inner insulation layer 102, a high-temperature polyester tape shielding layer 103, and an outer insulation layer 104. There are three conductors 101, which are distributed around the tensile core 2. The outer side of each conductor 101 is covered with an inner insulation layer 102. The outer side of each conductor 101 is covered with a high-temperature polyester tape shielding layer 103, and an outer insulation layer 104 is provided on the outer side of the high-temperature polyester tape shielding layer 103.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, in use, the main body 1 of the computer cable is composed of multiple conductors 101 in conjunction with an inner insulation layer 102, a high-temperature polyester tape shielding layer 103, and an outer insulation layer 104. The inner insulation layer 102 is used to achieve the insulation performance of the conductors 101. The high-temperature polyester tape shielding layer 103 and the outer insulation layer 104 are used to enhance the insulation performance and prevent external signal interference. The tensile core 2 is used to achieve the central support of the main body 1 of the computer cable and improve the tensile strength of the main body 1 of the computer cable.

[0028] The main body 1 of the computer cable is equipped with a tensile buffer component;

[0029] The tensile buffer assembly includes tensile buffer columns 3 uniformly arranged inside the computer cable body 1, and the tensile buffer columns 3 are all made of rubber. The gaps between the tensile buffer columns 3 are filled with halogen-free low-smoke flame-retardant filling rope 4. The cross-section of the tensile buffer columns 3 is circular. The tensile buffer columns 3 are distributed in a ring around the conductor 101 and the outer periphery of the inner insulation layer 102.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, during use, multiple tensile buffer columns 3 can generate performance. Multiple columns are set up to effectively resist external impact forces and have good tensile strength. Halogen-free low-smoke flame-retardant filler rope 4 is filled between the tensile buffer columns 3, which gives the computer cable body 1 good flame-retardant performance and makes the computer cable body 1 safer to use.

[0031] The outer side of the main body 1 of the computer cable is covered with a wear-resistant protective sleeve 5, and the wear-resistant protective sleeve 5 is surrounded by multiple metal reinforcing wires 6 arranged in a circular array.

[0032] Multiple metal reinforcing wires 6 are arranged in a ring around the wear-resistant protective sleeve 5. The metal reinforcing wires 6 are copper wires.

[0033] Specifically, such as Figure 1 , Figure 3 As shown, when in use, the arrangement of the annularly distributed metal reinforcing wires 6 enhances the overall structural strength;

[0034] The metal reinforcing wire 6 is wrapped with a PVC protective sleeve 8, and the metal reinforcing wire 6 inside the PVC protective sleeve 8 is evenly filled with dense asbestos wires 7.

[0035] The outer side of the PVC protective cover 8 is coated with an anti-corrosion coating 9, and the anti-corrosion coating 9 is a fluorocarbon resin coating.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, during use, while the internal structure of the computer cable body 1 is reinforced by metal reinforcing wires 6, dense asbestos fibers 7 are filled between the metal reinforcing wires 6. The dense asbestos fibers 7 are a material with good insulation properties. Filling between the metal reinforcing wires 6 effectively isolates the electrical conduction between the metal reinforcing wires 6 and prevents current from flowing between the metal reinforcing wires 6, thereby improving the insulation performance of the entire structure. An anti-corrosion coating 9 is applied to the PVC protective sleeve 8. It is a fluorocarbon resin coating with good mechanical properties, weather resistance, stain resistance, and chemical resistance, making the PVC protective sleeve 8 have good anti-corrosion performance.

[0037] Working principle: When this utility model is in use, firstly, the main body 1 of the computer cable is composed of a conductor 101, an inner insulation layer 102, a high-temperature polyester tape shielding layer 103, and an outer insulation layer 104. The inner insulation layer 102 is used to achieve initial insulation. Then, the cooperation of the high-temperature polyester tape shielding layer 103 and the outer insulation layer 104 effectively prevents electromagnetic interference and helps to improve the overall structural strength of the main body 1 of the computer cable. Next, an aramid fiber tensile core 2 is set at the center of the main body 1 of the computer cable to effectively resist external tensile force and prevent deformation of the main body 1 of the computer cable.

[0038] Secondly, multiple rubber tensile buffer pillars 3 are filled around the multiple conductors 101. The tensile buffer pillars 3 can effectively absorb external impact force and reduce the damage to the internal structure of the computer cable body 1 during the stretching process. Halogen-free low-smoke flame-retardant filler rope 4 is filled between the tensile buffer pillars 3 inside the computer cable body 1. This enhances the tightness between the conductors 101 and the tensile buffer pillars 3, while the flame-retardant properties of the halogen-free low-smoke flame-retardant filler rope 4 improve the safety of the computer cable body 1.

[0039] Finally, a wear-resistant protective sleeve 5 is wrapped around the main body 1 of the computer cable. The wear-resistant protective sleeve 5 is made of polyethylene (PE) material, which has good wear resistance. Then, multiple metal reinforcing wires 6 are evenly arranged around the wear-resistant protective sleeve 5. A PVC protective sleeve 8 is wrapped around the metal reinforcing wires 6. Dense asbestos fibers 7 are filled between the metal reinforcing wires 6 inside the PVC protective sleeve 8. The combination of metal reinforcing wires 6 and dense asbestos fibers 7 can enhance the tensile strength of the main body 1 of the computer cable and prevent deformation of the main body 1 from affecting its use. The PVC protective sleeve 8 that wraps the outermost part of the main body 1 of the computer cable improves the overall strength of the main body 1 of the computer cable and protects the internal structure of the main body 1 of the computer cable.
