Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and in particular to a wear-resistant wire and cable. Background Technology

[0002] A cable is an electrical energy or signal transmission device, typically a rope-like cable composed of several or groups of conductors (each group containing at least two conductors) twisted together. Each group of conductors is insulated from each other and is often twisted around a central conductor, with the entire cable covered by a highly insulating outer layer. As a component of power transmission, wires and cables have advantages such as small footprint, high reliability, and the ability to withstand ultra-high voltage. Their installation environment is usually one that is not directly exposed to sunlight or has a suitable temperature; they are typically installed on exterior walls, in conduits, or on overhead power lines.

[0003] However, existing wires and cables are prone to friction with the ground or installation site during installation and movement, which causes wear on the surface of the wires and cables and affects the safety of their use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a wear-resistant wire and cable to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of the present invention provides a wear-resistant wire and cable, comprising a conductive core for power transmission, wherein the surface of the conductive core is covered with an insulating protective sleeve for protection, the surface of the insulating protective sleeve is covered with a deformation support sleeve made of elastic material, the surface of the deformation support sleeve is covered with a textured protective sleeve made of wear-resistant material, the surface of the textured protective sleeve is covered with an insulating isolation layer made of insulating material, the surface of the insulating isolation layer is covered with a buffer layer made of flexible material, the surface of the buffer layer is covered with a shaping protective layer for protection, the surface of the shaping protective layer is covered with an armored sheath made of high-strength material, and the interior of the armored sheath is provided with a protruding protective strip made of elastic material.

[0006] Preferably, in any of the above embodiments, the conductive core is composed of several conductive bodies wound together, and the interior of the insulating protective sleeve has an insulating slot to accommodate the conductive core. The outer diameter of the insulating protective sleeve is the same as the inner diameter of the deformation support sleeve.

[0007] The above technical solution is adopted: the conductive core is composed of several conductive bodies wound together, which can effectively transmit power. The insulating slots inside the insulating protective sleeve tightly accommodate the conductive core, providing it with insulation protection and preventing current leakage. The outer diameter of the insulating protective sleeve is the same as the inner diameter of the deformation support sleeve, ensuring that the two fit tightly together, so that the deformation support sleeve can better support the insulating protective sleeve, ensuring the stability of the internal structure and reducing the impact of external factors on the conductive core.

[0008] Preferably, in any of the above embodiments, the deformation support sleeve is located between the insulating protective sleeve and the concave-convex protective sleeve, the surface of the concave-convex protective sleeve is provided with a raised semi-circular boss, and the interior of the semi-circular boss is provided with a groove that penetrates the concave-convex protective sleeve.

[0009] The above technical solution is adopted: the deformation support sleeve is located between the insulating protective sleeve and the concave-convex protective sleeve. Utilizing its own elasticity, it deforms when the wire and cable are subjected to external force, buffering the impact of external force on the internal structure and reducing the pressure on the insulating protective sleeve and conductive core. The semi-circular protrusions and internal grooves on the surface of the concave-convex protective sleeve increase its surface area and structural complexity. The semi-circular protrusions can disperse external pressure, and the grooves can absorb some pressure and impact force. The two work together to effectively reduce the force generated when the wire and cable move and improve the stability of use.

[0010] Preferably, in any of the above embodiments, the insulating isolation layer and the semi-circular boss are attached together, the insulating isolation layer is located between the semi-circular boss and the buffer layer, and sealing platforms are provided at both ends of the insulating isolation layer to cover the concave and convex protective sleeve.

[0011] The above technical solution involves an insulating isolation layer fitted with a semi-circular protrusion located between it and a buffer layer. This not only further enhances the insulation performance of the wires and cables but also blocks external electromagnetic interference, ensuring stable power transmission. The sealing platforms at both ends of the insulating isolation layer tightly cover the concave-convex protective sleeve, preventing dust, moisture, and other impurities from entering the wires and cables, protecting the internal structure from corrosion, and extending the service life of the wires and cables.

[0012] Preferably, in any of the above embodiments, the buffer layer has several circumferentially distributed buffer grooves inside, and the buffer layer is located between the insulating isolation layer and the shaping protective layer.

[0013] The above technical solution employs a buffer layer with circumferentially distributed buffer grooves, giving it excellent buffering performance. When the wires and cables are subjected to external impact or vibration, the buffer grooves can effectively absorb energy, reducing the transmission of impact force to the internal structure. Located between the insulation layer and the shaping protective layer, the buffer layer protects the insulation layer and provides buffering for the shaping protective layer, reducing the impact of external factors on the wires and cables and ensuring their stable operation.

[0014] Preferably, in any of the above embodiments, the two ends of the shaping protective layer are provided with annular baffles to block and protect the buffer layer, and the interior of the armor sleeve is provided with a number of protective grooves for fixing protruding protective strips.

[0015] The above technical solution employs the following: the annular baffles at both ends of the shaped protective layer effectively block the buffer layer, preventing it from shifting or deforming during use and ensuring the buffering effect of the buffer layer. The armor sheath is made of high-strength material with excellent wear resistance, providing robust external protection for wires and cables. The protective grooves inside precisely fix the protruding protective strips, ensuring that the protruding protective strips enhance wear resistance without affecting the overall performance of the armor sheath.

[0016] Preferably, in any of the above embodiments, the protruding protective strip includes an elastic rubber rod made of elastic material and a wear-resistant rubber sleeve for protection. The elastic rubber rod is fixedly installed inside the armor sleeve, and the surface of the elastic rubber rod is covered with the wear-resistant rubber sleeve that is fixedly installed with the armor sleeve.

[0017] The above technical solution involves fixing the elastic rubber rod of the protruding protective strip inside the armored sheath. Utilizing its own elasticity, the wire and cable bounce a certain amount during installation and movement, reducing the friction time with the ground or installation site. The wear-resistant rubber sleeve on the surface not only enhances the wear resistance of the protruding protective strip itself but also tightly integrates with the armored sheath to jointly protect the wire and cable, further improving the overall wear resistance.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. An armored sheath is installed on the outer surface of the wire and cable to enhance its overall wear resistance. An elastic protective strip is installed inside the armored sheath. The elasticity of this strip allows the wire and cable to bounce to a certain extent during installation and movement, reducing the time the wire and cable rubs against the ground or installation location, thus reducing wear caused by movement. Simultaneously, a buffer layer is installed inside the armored sheath to reduce the impact of bouncing on the internal structure of the wire and cable, improving the safety of installation and movement, and enhancing the wear resistance of the wire and cable.

[0020] 2. Install a deformation support sleeve made of elastic material inside the wire and cable. The elasticity of the deformation support sleeve itself protects the inside of the wire and cable, reducing the impact of external forces on the inside of the wire and cable. At the same time, install a concave-convex protective sleeve. The change of the concave-convex protective sleeve itself absorbs the force generated by the movement of the wire and cable to a certain extent, thereby improving the stability of the wire and cable in use.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0029] like Figure 1-4 As shown, an embodiment of the present invention provides a wear-resistant wire and cable, comprising a conductive core 1 for power transmission, an insulating protective sleeve 2 covering the surface of the conductive core 1 for protection, a deformation support sleeve 3 made of elastic material covering the surface of the insulating protective sleeve 2, a wear-resistant protective sleeve 4 made of wear-resistant material covering the surface of the deformation support sleeve 3, an insulating isolation layer 5 made of insulating material covering the surface of the protective sleeve 4, a buffer layer 6 made of flexible material covering the surface of the insulating isolation layer 5, a shaping protective layer 7 covering the surface of the buffer layer 6 for protection, an armored sheath 8 made of high-strength material covering the surface of the shaping protective layer 7, and a protruding protective strip 9 made of elastic material inside the armored sheath 8.

[0030] Preferably, in any of the above schemes, the conductive core 1 is composed of several conductive bodies wound together, and the insulating protective sleeve 2 has an insulating slot to accommodate the conductive core 1 inside. The outer diameter of the insulating protective sleeve 2 is the same as the inner diameter of the deformation support sleeve 3.

[0031] The above technical solution is adopted: the conductive core 1 is composed of several conductive bodies wound together, which can effectively transmit power. The insulating slots inside the insulating protective sleeve 2 tightly accommodate the conductive core 1, providing it with insulation protection and preventing current leakage. The outer diameter of the insulating protective sleeve 2 is the same as the inner diameter of the deformation support sleeve 3, ensuring that the two fit tightly together, so that the deformation support sleeve 3 can better support the insulating protective sleeve 2, ensuring the stability of the internal structure and reducing the influence of external factors on the conductive core 1.

[0032] Preferably, in any of the above schemes, the deformation support sleeve 3 is located between the insulating protective sleeve 2 and the concave-convex protective sleeve 4. The surface of the concave-convex protective sleeve 4 is provided with a raised semi-circular boss 10, and the interior of the semi-circular boss 10 is provided with a groove 11 that penetrates the concave-convex protective sleeve 4.

[0033] The above technical solution is adopted: the deformation support sleeve 3 is located between the insulating protective sleeve 2 and the concave-convex protective sleeve 4. Utilizing its own elasticity, it deforms when the wire and cable are subjected to external force, buffering the impact of external force on the internal structure and reducing the pressure on the insulating protective sleeve 2 and the conductive core 1. The semi-circular protrusion 10 and the internal groove 11 on the surface of the concave-convex protective sleeve 4 increase its surface area and structural complexity. The semi-circular protrusion 10 can disperse external pressure, and the groove 11 can absorb some pressure and impact force. The two work together to effectively reduce the force generated when the wire and cable move and improve the stability of use.

[0034] Preferably, in any of the above embodiments, the insulating isolation layer 5 and the semi-circular boss 10 are attached to each other, the insulating isolation layer 5 is located between the semi-circular boss 10 and the buffer layer 6, and the two ends of the insulating isolation layer 5 are provided with sealing platforms 12 to cover the concave and convex protective sleeve 4.

[0035] The above technical solution is adopted: the insulating isolation layer 5 is attached to the semi-circular protrusion 10 and located between it and the buffer layer 6. This not only further enhances the insulation performance of the wire and cable, but also blocks external electromagnetic interference and ensures stable power transmission. The sealing platforms 12 at both ends of the insulating isolation layer 5 tightly cover the concave and convex protective sleeve 4 to prevent dust, moisture and other impurities from entering the wire and cable, protect the internal structure from corrosion and extend the service life of the wire and cable.

[0036] Preferably, in any of the above schemes, the buffer layer 6 has a plurality of circumferentially distributed buffer grooves 13 inside, and the buffer layer 6 is located between the insulating isolation layer 5 and the shaping protective layer 7.

[0037] The above technical solution employs a buffer layer 6 with circumferentially distributed buffer grooves 13, giving it excellent buffering performance. When the wires and cables are subjected to external impact or vibration, the buffer grooves 13 can effectively absorb energy, reducing the transmission of impact force to the internal structure. The buffer layer 6 is located between the insulation layer 5 and the shaping protective layer 7, protecting the insulation layer 5 and providing buffering for the shaping protective layer 7, reducing the impact of external factors on the wires and cables, and ensuring their stable operation.

[0038] Preferably, either of the above-mentioned schemes has annular baffles 14 at both ends of the shaping protective layer 7 to block and protect the buffer layer 6, and the armor sleeve 8 has a number of protective grooves with fixed protruding protective strips 9 inside.

[0039] The above technical solution is adopted: the annular baffles 14 at both ends of the shaped protective layer 7 can effectively block the buffer layer 6, prevent it from shifting or deforming during use, and ensure the buffering effect of the buffer layer 6. The armor sheath 8 is made of high-strength material and has excellent wear resistance, providing a solid external protection for wires and cables. The protective groove opened inside it accurately fixes the protruding protective strip 9, so that the protruding protective strip 9 enhances wear resistance without affecting the overall performance of the armor sheath 8.

[0040] Preferably, the protruding protective strip 9 includes an elastic rubber rod 91 made of elastic material and a wear-resistant rubber sleeve 92 for protection. The elastic rubber rod 91 is fixedly installed inside the armor sleeve 8, and the surface of the elastic rubber rod 91 is covered with the wear-resistant rubber sleeve 92 fixedly installed with the armor sleeve 8.

[0041] The above technical solution is adopted: the elastic rubber rod 91 of the protruding protective strip 9 is fixed inside the armored sheath 8. Utilizing its own elasticity, the wire and cable will bounce a certain amount when they are installed and moved, reducing the friction time with the ground or installation site. The wear-resistant rubber sleeve 92 on the surface not only enhances the wear resistance of the protruding protective strip 9 itself, but also tightly combines with the armored sheath 8 to jointly protect the wire and cable, further improving the overall wear resistance.

[0042] The working principle of this utility model of a wear-resistant wire and cable is as follows:

[0043] The insulating protective sleeve 2 provides insulation protection for the conductive core 1, preventing current leakage. When the wire and cable are subjected to external friction or collision, the deformation support sleeve 3, with its own elasticity, buffers the impact of external forces on the internal structure, protecting the insulating protective sleeve 2 and the conductive core 1. The semi-circular protrusions 10 on the surface of the concave-convex protective sleeve 4 and the internal grooves 11 work together to disperse and absorb external pressure and impact. The insulating isolation layer 5 further enhances the insulation performance and blocks electromagnetic interference. The sealing platforms 12 at both ends prevent impurities from entering. The buffer grooves 13 inside the buffer layer 6 absorb energy and reduce the impact of external impacts on the interior. The annular baffles 14 at both ends of the shaping protective layer 7 ensure the stability of the buffer layer 6. The armored sheath 8, with its high-strength material, provides solid external protection. The internal protruding protective strip 9, with its elastic rubber rods 91, causes the wire and cable to bounce during installation and movement, reducing the friction time with the outside world. The wear-resistant rubber sleeve 92 enhances its own wear resistance.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] 1. An armored sheath 8 is installed on the outer surface of the wire and cable to enhance the overall wear resistance of the wire and cable. A protruding protective strip 9 made of elastic material is installed inside the armored sheath 8. The elasticity of the protruding protective strip 9 allows the wire and cable to bounce to a certain extent during the installation and movement of the wire and cable, reducing the time of friction between the wire and cable and the ground or installation location, thereby reducing the wear caused by the movement of the wire and cable. At the same time, a buffer layer 6 is installed inside the armored sheath 8 to reduce the impact of the bounce on the inside of the wire and cable, improve the safety of the installation and movement of the wire and cable, and enhance the wear resistance of the wire and cable.

[0046] 2. An elastic support sleeve 3 is installed inside the wire and cable. The elasticity of the elastic support sleeve 3 protects the inside of the wire and cable, reducing the impact of external forces on the inside of the wire and cable. At the same time, a concave-convex protective sleeve 4 is installed. The concave-convex protective sleeve 4 absorbs the force generated by the movement of the wire and cable to a certain extent, thereby improving the stability of the wire and cable in use.
