Description

Technical Field

[0001] This invention relates to the field of cable technology, and in particular to a computer instrument cable that is easy to lay and maintain. Background Technology

[0002] In the installation and use of computer instruments, cable laying and subsequent maintenance are crucial aspects, directly impacting installation efficiency and long-term stable operation. Currently, existing computer instrument cables generally suffer from the following practical shortcomings: difficult laying; poor bending performance, making them difficult to handle and prone to damage in confined spaces requiring frequent bending; insufficient tensile and abrasion resistance; and easy damage to the sheath layer during laying and use. Inconvenient maintenance; difficulty in quickly identifying different specifications and uses when multiple cables are laid simultaneously; lack of clear positioning markers makes it difficult to quickly locate faults during maintenance; and inefficient and poorly sealed traditional wiring methods for connecting cables to equipment. While existing technologies offer some improvements to address these issues, their complex designs, high costs, and inability to simultaneously solve multiple problems such as difficult laying and inconvenient maintenance limit their practicality. Therefore, developing a computer instrument cable that is simple in structure, low in cost, easy to lay and maintain, and possesses excellent tensile and abrasion resistance has significant practical implications and widespread value. Summary of the Invention

[0003] The technical problem to be solved by this invention is that existing computer instrument cables are difficult to lay, inconvenient to maintain, have insufficient tensile and abrasion resistance, and lack intelligent identification capabilities.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: a computer instrument cable that is easy to lay and maintain, comprising a cable body, wherein the cable body comprises, from the inside to the outside, a conductor core, an insulation layer, a filling layer, and a sheath layer; multiple reinforcing ribs are evenly arranged along the length direction on the outer side of the cable body, and the reinforcing ribs are fixedly connected to the cable body by connecting strips, the inner side of the connecting strips being integrally formed with the outer surface of the sheath layer, and the connecting strips having marking grooves along the length direction, into which replaceable identification tags are embedded; the outer side of the sheath layer has anti-slip textures, and positioning marks are spaced along the length direction on the sheath layer; quick connectors are fixedly provided at both ends of the cable body, and the quick connectors are provided with locking devices and sealing gaskets; an elastic buffer core is embedded inside the reinforcing ribs, an RFID electronic tag is also provided in the marking grooves, and a temperature sensing optical fiber is embedded inside the sheath layer.

[0005] Furthermore, the conductor core is made of multiple strands of copper wire twisted together, with a single wire diameter of 0.1-0.2 mm and a twisting pitch of 8-12 times the conductor core diameter; the insulation layer is made of polyvinyl chloride material with a thickness of 0.6-1.0 mm, and the outer surface of the insulation layer is coated with an anti-interference shielding coating.

[0006] Furthermore, the filling layer is made of polypropylene fiber material with added halogen-free flame retardant masterbatch, with a filling density of not less than 95% and a flame retardant rating of VW-1.

[0007] Furthermore, the sheath layer is made of polyvinyl chloride or low-smoke halogen-free polyolefin material, with a thickness of 1.0-1.4 mm and a Shore hardness of 80-85D.

[0008] Furthermore, the number of reinforcing ribs is 3-4, evenly distributed in a ring, the reinforcing ribs are made of glass fiber reinforced plastic with a diameter of 1.0-1.5mm, and the elastic buffer core is made of silicone or thermoplastic elastomer material.

[0009] Furthermore, a flexible transition section is provided at the junction of the connecting strip and the reinforcing rib. The inner side of the connecting strip is integrally formed with the outer surface of the sheath layer, with a thickness of 0.3-0.5mm and a width of 1.5-2.0mm.

[0010] Furthermore, the anti-slip texture is annular or spiral; the positioning mark is an annular protrusion with a height of 0.2-0.3mm, and the surface of the positioning mark is pressed with precise scale lines.

[0011] Furthermore, the locking device of the quick connector includes a threaded locking device and an anti-disengagement buckle, and the sealing gasket is a multi-layer silicone rubber composite sealing gasket.

[0012] Furthermore, the outer side of the cable body is covered with a tearable protective film, which completely covers the sheath layer and the marking groove area.

[0013] Furthermore, the marking groove is a U-shaped groove with a depth of 0.5-0.8 mm and a width of 2.0-3.0 mm, and the surface of the marking plate is provided with a wear-resistant coating.

[0014] The beneficial effects of this invention are as follows: The use of ultra-fine multi-strand copper wire stranded conductors enhances cable flexibility; the integration of reinforcing ribs with built-in elastic buffer cores and flexible transition sections eliminates stress concentration during bending; the combination of anti-slip textures and a tearable protective film increases laying friction to protect the sheath; the glass fiber reinforced plastic reinforcing ribs have a tensile strength of not less than 200MPa; and the high-density filling layer enhances resistance to deformation, effectively solving the problems of difficult laying, insufficient tensile strength, and insufficient wear resistance. Visual differentiation is achieved through marking grooves and replaceable labels; precise point positioning is achieved by pressing scale lines onto the surface of the positioning marks; the quick connector uses a dual structure of threaded locking and anti-loosening buckles to prevent loosening and falling off; multi-layer silicone rubber sealing gaskets improve waterproof, dustproof, and oil-proof performance; and temperature-sensing optical fibers embedded in the sheath layer monitor temperature rise in real time and provide early warning of overheating faults, solving the problems of inconvenient maintenance, difficult identification, and poor connection sealing.
