Description

Technical Field

[0001] The utility model belongs to the technical field of wires and cables, and in particular relates to a signal cable for computers that is anti-static short-circuit. Background Art

[0002] With the rapid development of information technology, computers have become an indispensable tool in modern society. In computer systems, the motherboard, as a core component, is crucial for the stable operation of the entire system. Signal cables, the bridge connecting the motherboard to various components, have a direct impact on the stability and reliability of the computer.

[0003] While traditional computer signal cables can perform basic signal transmission tasks, they often present potential risks such as static electricity accumulation and short circuits in complex and changing operating environments. Static electricity accumulation not only interferes with normal signal transmission but can also damage electronic devices and sensitive components, shortening their lifespan. Short circuits can cause circuit burnout and even lead to serious consequences such as fires.

[0004] To address these issues, some computer signal cables with anti-static properties have appeared on the market. However, these cables often suffer from defects such as poor conductivity, insufficient flame retardancy, and poor scratch and tensile strength. Furthermore, some cables are cumbersome to install, use, and maintain, causing inconvenience to users.

[0005] Therefore, it is particularly important to develop a computer signal cable that has excellent electrical conductivity, flame retardancy, scratch resistance and tensile strength, and can effectively prevent static short circuit and accumulation. Utility Model Content

[0007] The utility model is achieved in this way: an anti-static short-circuit computer signal cable includes three conductors, the conductors are twisted copper conductors, the outer side of the conductors is an anti-static insulation layer made of anti-static polyvinyl chloride material, the outer sides of the three conductors with anti-static insulation layers are sequentially provided with an inner sheath, a shielding layer and an outer sheath; wherein the inner sheath is extruded by a 60°C grade thermoplastic polyolefin material; the shielding layer is a double-layer structure, including an aluminum-plastic composite tape wrapping layer and a soft tinned copper wire braided layer wrapped around the outer side of the aluminum-plastic composite tape wrapping layer; the metal surface of the aluminum-plastic composite tape wrapping layer is provided with a drain wire; the outer sheath is made of a 60°C grade thermoplastic polyolefin material.

[0008] Further preferably, the surface of the conductor is smooth and the cross-section is circular.

[0011] More preferably, the thickness of the outer sheath is 1.0-1.5 mm, and the thickness of the inner sheath is 60%-80% of the thickness of the outer sheath.

[0012] The utility model has the following advantages and technical effects: the cable has good physical and mechanical properties and electrostatic dissipation protection performance.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] See also Figure 1 , an anti-static short-circuit computer signal cable, nominal cross-section: 0.5 ~ 2.5mm 2, Number of cable cores: multi-core, Rated voltage: 300V / 500V, Temperature range: -20~60℃; It includes three conductors 1, which are twisted copper conductors. When the conductors are twisted into cables, a pressing mold is used to smooth the surface of the conductors to reduce resistance, and the cross-section is circular; The outer side of the conductor is an antistatic insulation layer 2 made of antistatic polyvinyl chloride material. The conductive agent in the antistatic polyvinyl chloride material can effectively conduct electricity and quickly release static electricity to the ground, avoiding the accumulation and discharge of static electricity, thereby preventing short-circuit damage between the computer power supply and the motherboard. This design significantly improves the safety and reliability of the cable. The three conductors with antistatic insulation layers are surrounded by an inner sheath 3, a shielding layer 4, and an outer sheath 5. The inner sheath is extruded from a 60°C-grade thermoplastic polyolefin material, which has excellent heat resistance and mechanical properties and protects the insulation layer from external damage. The addition of antistatic masterbatch prevents static electricity generation in the inner sheath, further enhancing the cable's antistatic performance. The shielding layer is a double-layer structure, comprising an aluminum-plastic composite tape wrapping layer and a soft tinned copper braid wrapped around the outer surface of the aluminum-plastic composite tape wrapping layer. A drain wire is provided on the metal surface of the aluminum-plastic composite tape wrapping layer. Together, the aluminum-plastic composite tape wrapping layer and the soft tinned copper braiding layer form a multi-shielding layer, effectively reducing crosstalk and external interference between circuits and improving the cable's anti-interference capability. Furthermore, the drain wire design can direct static electricity released by the insulation layer to the ground, further enhancing the cable's anti-static performance. Furthermore, the soft tinned copper braid enhances the cable's tensile and tear resistance. The outer sheath, made from 60°C-grade thermoplastic polyolefin, is flame-retardant, oil-resistant, flexible, wear-resistant, and corrosion-resistant, making it suitable for the compact installation and use environments found in computer mainframes. This design not only increases the cable's durability and service life, but also ensures its proper operation in harsh environments.

[0017] In summary, the anti-static short-circuit computer signal cable described in this application achieves excellent anti-static performance, anti-interference capabilities, heat resistance, mechanical properties, and durability through a series of innovative technical features. These technical features work together to enable the cable to adapt to the compact installation and use environment of a computer host, while simplifying installation and maintenance operations and providing a strong guarantee for the stable operation of the computer system.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
