Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a corrugated armored cable with compression resistance. Background Technology

[0002] A cable is a collection of conductors used to transmit power, signals, or data. It is usually composed of multiple conductors wrapped together by insulating material to form a whole cable. Depending on the application, cables can be divided into power cables, control cables, and signal cables, etc. They are widely used in construction, industry, and communications. Cables refer to materials used for power, communication, and related transmission purposes. With the development of society, the scope and occasions of cable use are increasing, and the requirements for cables are also becoming higher, mainly reflected in comprehensive requirements.

[0003] In the existing technology, among the many external influencing factors, impact, pressure and tension are the main factors that threaten cables. When traditional cables are subjected to external impact or pressure, their outer protective layer is often easily damaged, which leads to the exposure or damage of the cable core inside the cable, affecting the normal transmission function of the cable and limiting the application of traditional cables in certain special or extreme environments.

[0004] Therefore, a corrugated armored extrusion-resistant cable is proposed to solve the aforementioned technical problems of easy damage and breakage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a corrugated armored anti-extrusion cable with high strength, which solves the problem that the outer protective layer of traditional cables is often easily damaged when faced with external impacts or pressure, resulting in the exposure or damage of the cable core inside the cable.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a corrugated armored anti-extrusion cable, comprising a cable core and a corrugated armor assembly disposed on the cable core;

[0007] The corrugated armor assembly includes an armored protective layer disposed outside the cable core, a corrugated protective element disposed on the outer side of the armored protective layer, an anti-detachment layer disposed on the inner side of the armored protective layer, and an anti-compression layer disposed on the inner side of the anti-detachment layer.

[0008] Furthermore, the armor protective layer is a carbon fiber composite material layer, and the armor protective layer is fixed to the outside of the anti-detachment layer with adhesive.

[0009] Furthermore, the number of corrugated protective components is several, and the several corrugated protective components are equidistantly distributed on the outside of the armor protective layer.

[0010] Furthermore, the corrugated protective component is made of any one of galvanized steel, aluminum alloy, or stainless steel.

[0011] Furthermore, the anti-detachment layer is a polyester film layer, and the anti-compression layer is a glass fiber woven layer.

[0012] Furthermore, an insulation layer is provided on the outer side of the cable core, and a shielding layer is provided on the outer side of the insulation layer. The shielding layer is located inside the compression-resistant layer, and a number of reinforcing ribs are provided between the insulation layer and the shielding layer.

[0013] Furthermore, the shielding layer is a copper braided layer, and the insulating layer is a polytetrafluoroethylene layer.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This anti-extrusion cable with a corrugated armor structure, through the setting of an armor protective layer and the selection of carbon fiber composite materials, combines high strength and lightweight characteristics, can resist external mechanical damage, improve the strength of the cable itself, and at the same time, the external pressure is dispersed by the outer corrugated protective component, and the anti-extrusion layer absorbs impact energy, significantly improving the structural integrity of the cable under extreme working conditions such as pressure and impact.

[0016] 2. This anti-extrusion cable with a corrugated armor structure enhances the tensile strength of the insulation and shielding layers by adding reinforcing ribs to the outside of the cable core, reducing the risk of deformation. At the same time, it can effectively block electromagnetic interference and ensure the stability of signal and power transmission. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1 , Figure 2 and Figure 4 The compression-resistant cable with corrugated armor structure in this embodiment includes a cable core 100 and a corrugated armor assembly 200 disposed on the cable core 100.

[0024] The corrugated armor assembly 200 includes an armor protection layer 201 disposed outside the cable core 100, a corrugated protective element 202 disposed on the outer side of the armor protection layer 201, an anti-detachment layer 203 disposed on the inner side of the armor protection layer 201, and an anti-compression layer 204 disposed on the inner side of the anti-detachment layer 203.

[0025] When applied, under external compressive force, such as pressure from heavy objects or mechanical impact, the corrugated protective component 202 is the first to come into contact with the external force. Its corrugated structure transforms the point-like concentrated stress into dispersed stress along the corrugated surface, avoiding localized damage caused by stress concentration. The armored protective layer 201 provides rigid support, blocking the penetration of external force inward. The anti-compression layer 204 undergoes elastic deformation, absorbing the remaining impact energy, significantly improving the structural integrity of the cable under extreme conditions such as pressure and impact. Example

[0026] The basic content is the same as in Example 1, except that:

[0027] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the armor protective layer 201 is a carbon fiber composite material layer, and the armor protective layer 201 is fixed to the outside of the anti-detachment layer 203 by adhesive.

[0028] Specifically, the armor protective layer 201 is made of carbon fiber composite material, which has both high strength and lightweight characteristics, can resist external mechanical damage, and improve the strength of the cable itself.

[0029] There are several corrugated protective components 202, which are equidistantly distributed on the outside of the armor protective layer 201.

[0030] It should be noted that the equidistantly distributed corrugated protective elements 202 form a continuous mechanical support network, which disperses the local impact load to adjacent corrugated units, thereby significantly improving the compressive strength of the cable.

[0031] The anti-detachment layer 203 is a polyester film layer, and the compression-resistant layer 204 is a glass fiber braided layer. Glass fiber braided fabric has strong tensile strength, compressive strength and high temperature resistance. It is usually used as a cable protection layer in high temperature or high pressure environments and can effectively resist mechanical damage and environmental changes.

[0032] Furthermore, the armor protective layer 201 is bonded to the polyester film anti-detachment layer 203 with adhesive, which improves the interlayer peel strength and completely eliminates interlayer slippage. The polyester film is a high-strength film material with strong adhesion, which can effectively ensure the adhesion between layers and prevent the inner layer from falling off. Example

[0033] The basic content is the same as in Examples 1 and 2, except that:

[0034] Please see Figure 3-4 In this embodiment, an insulation layer 101 is provided on the outside of the cable core 100, and a shielding layer 102 is provided on the outside of the insulation layer 101. The shielding layer 102 is located on the inside of the compression-resistant layer 204, and a plurality of reinforcing ribs 103 are provided between the insulation layer 101 and the shielding layer 102.

[0035] It should be noted that the reinforcing rib 103 works in conjunction with the glass fiber anti-compression layer 204 to uniformly transmit external pressure and convert external impact into uniformly distributed internal stress, protecting the brittle insulating material. At the same time, it fills the gap between the insulating layer 101 and the shielding layer 102, preventing interlayer slippage.

[0036] The shielding layer 102 is a copper braided layer, and the insulation layer 101 is a polytetrafluoroethylene layer.

[0037] Specifically, polytetrafluoroethylene (PTFE) has excellent high temperature resistance, corrosion resistance, and superior electrical insulation properties. Copper braided mesh is a mesh structure woven from copper wires, which has very good mechanical strength and electrical conductivity. It is mainly used to provide electromagnetic shielding, while also providing a certain tensile strength for cables. Copper braided mesh is suitable for environments that require high shielding effectiveness and durability.

[0038] In summary, the working principle of the above-mentioned corrugated armored compression-resistant cable is as follows:

[0039] When the cable is subjected to external compressive force, such as pressure from heavy objects or mechanical impact, the corrugated protective element 202 is the first to come into contact with the external force. Its corrugated structure transforms the point-concentrated stress into dispersed stress along the corrugated surface, avoiding local damage caused by stress concentration. The armored protective layer 201 provides rigid support and blocks the penetration of external force inward. The compression-resistant layer 204 undergoes elastic deformation to absorb the remaining impact energy, significantly improving the structural integrity of the cable under extreme conditions such as pressure and impact. The armored protective layer 201 is made of carbon fiber composite material, which has both high strength and lightweight characteristics, and can resist external mechanical damage and improve the strength of the cable itself. The equidistantly distributed corrugated protective elements 202 form a continuous mechanical support network, dispersing the local impact load to adjacent corrugated units, which significantly improves the compressive strength of the cable. The reinforcing rib 103 and the glass fiber compression-resistant layer 204 work together to uniformly transmit external pressure and transform external impact into uniformly distributed internal stress, protecting the brittle insulation material. At the same time, they fill the gap between the insulation layer 101 and the shielding layer 102, preventing interlayer slippage.

[0040] Meanwhile, the insulation layer 101 is made of polytetrafluoroethylene (PTFE), which has excellent high temperature resistance, corrosion resistance and excellent electrical insulation properties. The shielding layer 102 is made of copper braided mesh, which is a mesh structure woven from copper wire. It has very good mechanical strength and electrical conductivity. It is mainly used to provide electromagnetic shielding and also provides a certain tensile strength to the cable. Copper braided mesh is suitable for environments that require high shielding effect and durability.
