Abstract
Description
Technical Field
[0001] This application relates to the technical field of cables, and in particular to a tensile-resistant cable. Background Technology
[0002] A cable is a conductor made of one or more insulated conductors and an outer insulating protective layer, used to transmit electricity or information from one place to another. It is typically a rope-like cable made of several or groups of conductors (at least two conductors per group) twisted together, with each group of conductors insulated from each other and often twisted around a central core, the entire cable covered with a highly insulating outer layer.
[0003] In complex operating environments such as construction sites and mines, cables are frequently subjected to pulling, dragging, and external compression, highlighting certain shortcomings of existing cables. Conventional cables often rely on a single sheath for protection, making the internal core prone to breakage under tension, leading to power outages or signal loss and affecting the normal operation of equipment. Utility Model Content
[0004] To address the problems mentioned in the background art, this application provides a tensile-resistant cable.
[0005] The tensile-resistant cable provided in this application adopts the following technical solution:
[0006] A tensile-resistant cable includes an outer protective layer, a middle tensile-resistant layer, an inner buffer layer, and a conductor.
[0007] The outer protective layer is a high-strength plastic sheath, which provides wear-resistant and cut-resistant protection.
[0008] The intermediate tensile layer is a metal woven mesh, used to disperse tensile force;
[0009] The inner buffer layer is an elastic insulating tube that provides buffer protection for the wire core.
[0010] The core is made of multiple strands of soft copper wire twisted together and is used to transmit power or signals.
[0011] Preferably, the outer protective layer is made of neoprene rubber, and the middle tensile layer is a tin-plated copper woven mesh.
[0012] Preferably, the inner buffer layer is made of thermoplastic elastomer and has elastic recovery properties.
[0013] Preferably, the intermediate tensile layer can also serve as a shielding layer, and an insulating coating can be added to the outside of the wire core to improve insulation and anti-interference performance.
[0014] In summary, this application includes the following beneficial technical effects:
[0015] Compared to existing technologies, this technology achieves layered dispersion and buffering of external forces through an outer protective layer, a middle metal braided mesh, and an inner buffer layer. The outer layer resists abrasion and cuts, the middle layer disperses tensile force, and the inner layer buffers and protects the conductor core, making the cable less prone to breakage or damage under pulling and dragging conditions, improving the cable's tensile strength, and ensuring stable power supply or signal transmission.

[0018] Explanation of reference numerals in the attached diagram: 1. Outer protective layer; 2. Middle tensile layer; 3. Inner buffer layer; 4. Core wire. Detailed Implementation
[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0020] This application discloses a tensile-resistant cable. (Refer to...) Figure 1-2 A tensile-resistant cable includes an outer protective layer 1, a middle tensile-resistant layer 2, an inner buffer layer 3, and a conductor 4.
[0021] The outer protective layer 1 is a high-strength plastic sheath. The sheath, made of high-strength plastic, has good wear resistance and cut resistance. As the first line of protection for the cable, it resists external sharp objects and external impacts.
[0022] The intermediate tensile layer 2 is a metal braided mesh that wraps around the inner structure in an "armor" shape. When subjected to tension, it can effectively disperse stress and prevent the inner core 4 from being directly subjected to excessive tension and breaking.
[0023] The inner buffer layer 3 is an elastic insulating tube, made of elastic insulating material (such as polyvinyl chloride elastomer), which provides a buffer space for the core 4 under tensile force, maintains the relative stability of the core 4, and at the same time plays an insulating protection role.
[0024] Core 4 is made of multiple strands of soft copper wire, containing multiple conductive cores. The number and specifications can be set according to requirements for transmitting power or signals.
[0025] The implementation principle of a tensile-resistant cable according to an embodiment of this application is as follows: Multiple strands of soft copper wire are twisted together at a set pitch to form a core 4 with certain tensile and bending resistance. An insulating coating can be applied to the surface of the core 4 as needed. An elastic insulating material is extruded into a tube and fitted onto the outside of the core 4 to form an inner buffer layer 3. The thickness and elasticity of the buffer layer are controlled by adjusting the extrusion process parameters. The intermediate tensile-resistant layer 2 is made of tin-plated copper wire, woven into a metal mesh at a set braiding density, and wrapped around the outside of the inner buffer layer 3 to form the intermediate tensile-resistant layer 2. During the braiding process, the metal mesh is ensured to be uniform and tight, without any missing braids or broken wires. Neoprene rubber is extruded using an extruder and wrapped around the outside of the intermediate tensile-resistant layer 2 to form an outer protective layer 1. The prepared cable undergoes tensile testing, insulation testing, and abrasion resistance testing to ensure that all performance indicators meet design requirements. When used in construction sites, mines, and other similar environments, the anti-slip texture of the outer protective layer 1 facilitates dragging and laying operations. When encountering tensile forces, the multi-layered protective structure disperses and buffers external forces, protecting the conductor 4 from damage. Regularly inspect the cable's appearance. If the outer protective layer 1 shows minor damage, it can be repaired with a special rubber repair agent. If the middle tensile layer 2 or the inner buffer layer 3 is severely damaged, replace the cable to ensure transmission safety.
[0026] During this process, the outer protective layer 1, the middle metal braided mesh, and the inner buffer layer 3 achieve layered dispersion and buffering of external forces. The outer layer resists abrasion and cutting, the middle layer disperses tensile force, and the inner layer buffers and protects the core 4, making the cable less prone to core breakage and damage under pulling and dragging scenarios, improving the cable's tensile strength, and ensuring stable power supply or signal transmission.
[0027] Reference Figure 1 and Figure 2 The intermediate tensile layer 2 can also serve as a shielding layer, and an insulating coating can be added to the outside of the wire core 4 to improve insulation and anti-interference performance.
