Description

Technical Field

[0001] This application relates to the field of cables, and more specifically, to a cut-resistant wire and cable. Background Technology

[0002] Cables are electrical transmission components composed of multiple conductors wrapped in insulating material. Functionally, cables can be divided into three categories: power cables for transmitting electricity, optical / communication cables for carrying information, and special industrial cables. Voltage levels range from 220V for household use to 500kV ultra-high voltage transmission systems. In scenarios such as rail transit, building power distribution, and submarine communications, cables transmit energy and data through underground burial, overhead lines, or conduit installation. The theft of power cables and stripping of copper conductors is a problem. Power cable interruptions cause widespread power outages and factory shutdowns, resulting in incalculable losses.

[0003] Current wires and cables are wrapped with an insulation layer for insulation, but the insulation layer is relatively soft and can be easily cut with pliers or knives, failing to protect the cable core and thus reducing the effectiveness of protection and the practicality of the device. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a cut-resistant wire and cable, which aims to improve the problem that the wire and cable are wrapped with an insulation layer for insulation. However, the insulation layer is relatively soft and can be easily cut by pliers or knives, which cannot protect the cable core, thereby reducing the protective effect and the practicality of the device.

[0005] This application provides a cut-resistant wire and cable, including a cable core body and a protective structure. The cable core body includes three cable core bodies. The protective structure includes an insulation component, a steel wire braided layer, and a cut-resistant layer. The cable core bodies are disposed within the insulation component. The steel wire braided layer is connected to the insulation component. The cut-resistant layer is fixedly connected to the outer ring of the steel wire braided layer.

[0006] In one specific implementation, the insulation component includes a first insulation layer and a second insulation layer, and the first insulation layer is fixedly connected to the outer ring of each of the three cable core bodies, with the first insulation layer disposed within the second insulation layer.

[0007] In the above implementation process, the insulation strength of the cable can be easily improved by setting the first insulation layer and the second insulation layer.

[0008] In one specific implementation, a pressure-resistant component is provided on one side of the second insulating layer. The pressure-resistant component includes a first rubber plate and a second rubber plate. The first rubber plate is fixedly connected to the second rubber plate, and one side of both the first rubber plate and the second rubber plate is fixedly connected to the second insulating layer.

[0009] In the above implementation process, the setting of the first rubber plate and the second rubber plate can facilitate the compression resistance of the cable at the same time. At the same time, the rubber material has good elasticity, which can buffer external impact force and protect the internal cable core body from damage.

[0010] In one specific implementation, the first rubber plate and the second rubber plate are arranged in a cross shape, and a plurality of the first rubber plate and the second rubber plate are evenly arranged.

[0011] In the above implementation process, the first rubber plate and the second rubber plate are arranged in a cross shape to effectively disperse external pressure, improve the overall pressure resistance of the cable, and enable it to maintain good shape and structural stability when subjected to external pressure.

[0012] In one specific implementation, a waterproof layer is fixedly connected to one side of the first rubber sheet and the second rubber sheet.

[0013] In the above process, the waterproof layer can prevent moisture from penetrating into the cable and extend the cable's service life.

[0014] In one specific implementation, a shielding layer is fixedly connected to the outer ring of the waterproof layer.

[0015] In the above implementation process, the shielding layer facilitates the blocking of interference from external electric and magnetic fields on the internal conductors, while preventing internal signals from leaking out and ensuring signal transmission stability.

[0016] In one specific implementation, the outer ring of the anti-cutting layer is fixedly connected to a wear-resistant layer.

[0017] In the above implementation process, the wear-resistant layer helps to resist external friction and scratches, protecting the internal structure from damage.

[0018] In one specific implementation, the outer ring of the waterproof layer is provided with a heat dissipation component, which includes a heat-conducting block, a mounting groove, and heat dissipation holes. A plurality of the heat-conducting blocks are fixedly connected to the outer ring of the waterproof layer. The shielding layer, the steel wire braided layer, and the anti-cutting layer are all provided with a plurality of mounting grooves. The heat-conducting blocks are disposed in the mounting grooves. The wear-resistant layer is provided with a plurality of heat dissipation holes, which are connected to the mounting grooves.

[0019] In the above implementation process, the setting of heat-conducting blocks, mounting grooves and heat dissipation holes facilitates the rapid conduction of internal heat from the heat-conducting blocks to the heat dissipation holes, and heat dissipation through air convection, keeping the cable working within a safe temperature range and preventing the cable from aging or being damaged due to overheating.

[0020] Compared with the prior art, the beneficial effects of this application are as follows: the steel wire braided layer and the anti-cutting layer facilitate the prevention of external force cutting the cable, thus providing convenient protection; the anti-compression component facilitates the cable's compressive strength, while the rubber material has good elasticity, which can buffer external impact and protect the internal cable core from damage; the heat dissipation component facilitates the heat conduction block to quickly conduct internal heat to the heat dissipation holes, and heat dissipation is achieved through air convection, keeping the cable operating within a safe temperature range and preventing the cable from aging or being damaged due to overheating.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Please see Figure 1 This application provides a cut-resistant wire and cable, including a cable core body 10 and a protective structure 20.

[0029] Please see Figure 1 and Figure 4 The cable core body 10 includes three cable core bodies 110.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The protective structure 20 includes an insulation component 210, a steel wire braided layer 220, and a cut-resistant layer 230. The cable core body 110 is disposed inside the insulation component 210. The steel wire braided layer 220 is connected to the insulation component 210. The cut-resistant layer 230 is fixedly connected to the outer ring of the steel wire braided layer 220. The cut-resistant layer 230 is made of aromatic polyamide fiber.

[0031] In a specific configuration, the insulation component 210 includes a first insulation layer 211 and a second insulation layer 212. The outer rings of the three cable core bodies 110 are all fixedly connected with the first insulation layer 211. The first insulation layer 211 is disposed within the second insulation layer 212. The insulation strength of the cable can be easily improved by the arrangement of the first insulation layer 211 and the second insulation layer 212.

[0032] In a specific configuration, a pressure-resistant component 240 is provided on one side of the second insulation layer 212. The pressure-resistant component 240 includes a first rubber plate 241 and a second rubber plate 242. The first rubber plate 241 and the second rubber plate 242 are fixedly connected. Both the first rubber plate 241 and the second rubber plate 242 are fixedly connected to the second insulation layer 212 on one side. The arrangement of the first rubber plate 241 and the second rubber plate 242 can facilitate the simultaneous compression resistance of the cable. At the same time, the rubber material has good elasticity, which can buffer external impact force and protect the internal cable core body 110 from damage.

[0033] In a specific configuration, the first rubber plate 241 and the second rubber plate 242 are arranged in a cross shape. A number of the first rubber plate 241 and the second rubber plate 242 are evenly arranged. The cross shape formed by the first rubber plate 241 and the second rubber plate 242 effectively disperses external pressure, improves the overall compressive strength of the cable, and enables it to maintain good shape and structural stability when subjected to external pressure.

[0034] In a specific configuration, a waterproof layer 250 is fixedly connected to one side of the first rubber plate 241 and the second rubber plate 242. The waterproof layer 250 prevents moisture from penetrating into the cable and extends the cable's service life.

[0035] In the specific setup, a shielding layer 260 is fixedly connected to the outer ring of the waterproof layer 250. The shielding layer 260 facilitates the blocking of interference from external electric and magnetic fields on the internal conductors, while preventing internal signals from leaking out and ensuring the stability of signal transmission.

[0036] In a specific configuration, the outer ring of the anti-cutting layer 230 is fixedly connected to a wear-resistant layer 270. The wear-resistant layer 270 helps to resist external friction and scratches, protecting the internal structure from damage.

[0037] In a specific configuration, a heat dissipation assembly 280 is provided around the outer ring of the waterproof layer 250. The heat dissipation assembly 280 includes a heat-conducting block 281, a mounting groove 282, and heat dissipation holes 283. Several heat-conducting blocks 281 are fixedly connected to the outer ring of the waterproof layer 250. Several mounting grooves 282 are provided through the shielding layer 260, the steel wire braided layer 220, and the anti-cutting layer 230. The heat-conducting blocks 281 are set in the mounting grooves 282. Several heat dissipation holes 283 are provided through the wear-resistant layer 270. The heat dissipation holes 283 are connected to the mounting grooves 282. The arrangement of the heat-conducting blocks 281, the mounting grooves 282, and the heat dissipation holes 283 facilitates the rapid conduction of internal heat from the heat-conducting blocks 281 to the heat dissipation holes 283. Heat is dissipated through air convection, keeping the cable operating within a safe temperature range and preventing the cable from aging or being damaged due to overheating.

[0038] The working principle of this type of cut-resistant wire and cable is as follows: When using the cut-resistant wire and cable, the cut-resistant layer 230 and the steel wire braid layer 220 provide cutting performance. The three cable core bodies 110 are double-wrapped by the first insulation layer 211 and the second insulation layer 212, which can improve the insulation strength. The first rubber plate 241 and the second rubber plate 242 arranged in a cross shape can disperse external pressure and buffer impact force to protect the internal cable core bodies 110. The waterproof layer 250 can block water penetration. The shielding layer 260 can suppress electromagnetic interference and prevent signal leakage. The wear-resistant layer 270 can resist external friction. When the cable is in use, the heat is conducted to the heat dissipation hole 283 through the heat conduction block 281, and the cable can dissipate heat by air convection.

[0039] It should be noted that the specific model and specifications of the cable core body 110 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
