Description

Technical Field

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

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for control installation, connecting equipment, transmitting power and so on. They are a common and indispensable item in daily life.

[0003] Modern cables often use a multi-layered structure to encase the cable core inside. During use, this results in poor tensile strength. If large tensile forces are applied to both ends, displacement between the layers can occur, causing the cable to deform and reducing its performance in the long run. Utility Model Content

[0004] To solve the above problems, this utility model provides a tensile-resistant cable.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tensile-resistant cable, comprising multiple cable cores, each of the multiple cable cores having an insulating layer on its outer wall, a protective layer being provided on the outer wall of the multiple cable cores, an outer sheath being provided on the outer wall of the protective layer, a reinforcing core being provided inside the protective layer, and a filling layer being provided between the reinforcing core, the cable cores, and the protective layer, and the reinforcing core, the cable cores, the protective layer, and the filling layer being produced by wrapping.

[0006] By adopting the above technical solution, when the cable body is in use, current is transmitted through multiple cable cores. During operation, these multiple cable cores are interconnected by insulation and filler layers, allowing each core to operate independently, thus improving the practicality of the device. Furthermore, during use, the reinforcing core, cable cores, protective layer, and filler layer are manufactured through a wrapping process. The reinforcing core enhances the tensile strength of the cable body, reducing the probability of deformation during use and thus improving the overall performance of the cable.

[0007] Furthermore, multiple raised rings are arrayed on the outer wall of the protective layer, and the raised rings are fixed to the protective layer. The protective layer is made of cross-linked polyethylene material, and the raised rings are made of cross-linked polyethylene material.

[0008] By adopting the above technical solution, the cross-linked polyethylene protective layer and the raised ring have good elasticity during cable use, thereby increasing the friction between the protective layer and the outer sheath. This reduces the probability of displacement between the protective layer and the outer sheath during use, thus reducing the probability of cable deformation. Furthermore, due to…Figure 2 As shown, multiple raised rings are arranged in a parallel array on the outer wall of the protective layer. These raised rings increase the surface roughness of the protective layer, thereby increasing the friction between the protective layer and the outer sheath. This further reduces the probability of displacement between the protective layer and the outer sheath, and consequently, the probability of deformation of the cable body. Furthermore, the cross-linked polyethylene material possesses excellent heat resistance, insulation, mechanical properties, and corrosion resistance, further reducing the probability of damage to the cable body during use and extending the service life of the device.

[0009] Furthermore, the outer wall of the reinforcing core is provided with an array of anti-slip textures, and the filling layer is made of glass fiber material.

[0010] By adopting the above technical solution, the filler layer made of glass fiber material has good tensile strength, elasticity, and dimensional stability, thereby further improving the tensile strength of the cable body and allowing it to return to its original shape after deformation, thus improving the overall performance of the cable body. Figure 3 As shown, the anti-slip texture increases the friction between the reinforcing core and the filling layer, thereby reducing the probability of displacement between the anti-slip texture and the filling layer, and thus reducing the probability of deformation of the cable body.

[0011] Furthermore, two connecting ears are symmetrically arranged on the outer wall of the outer skin, and each of the two connecting ears is provided with a tensile wire.

[0012] Furthermore, the tensile wire is made of galvanized soft copper wire.

[0013] By adopting the above technical solution, the tensile wire made of galvanized soft copper wire further improves the tensile performance of the cable body. In addition, the tensile wire made of galvanized soft copper wire has good flexibility. When in use, the good flexibility can help the cable body to return to its original position after bending, thereby reducing the probability of the cable body deforming after bending, thus improving the performance of the cable body.

[0014] Furthermore, the outer sheath is made of nylon, and the connecting ear is also made of nylon.

[0015] By adopting the above technical solution, the nylon outer sheath and connecting ears possess excellent wear resistance, thereby reducing the probability of damage to the sheath and connecting ears during use and extending the service life of the device. Furthermore, using the same material for the sheath and connecting ears reduces the probability of resistance between the two materials, thus improving the overall performance of the cable. In addition, the excellent tensile strength of nylon further enhances the tensile strength of the cable.

[0016] Furthermore, the outer wall of the protective layer is coated with fluorescent powder.

[0017] By adopting the above technical solution, when the outer skin of the package is damaged, the staff can observe the damage point of the outer skin through fluorescent powder, thereby reducing the difficulty of the staff in repairing the outer skin and thus reducing the difficulty of the staff's work.

[0018] Furthermore, the outer wall of the convex ring is provided with a circumferential array of multiple anti-slip grooves.

[0019] By adopting the above technical solution, the anti-slip groove further increases the friction between the protective layer and the outer sheath, thereby reducing the probability of displacement between the protective layer and the outer sheath, and further reducing the probability of deformation of the cable body.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when the cable body is in use, current is transmitted through multiple cable cores. During operation, the multiple cable cores are connected by insulation and filler layers, allowing each cable core to work independently, thereby improving the practicality of the device. Furthermore, during use, the reinforcing core, cable cores, protective layer, and filler layer are manufactured through a wrapping process. The reinforcing core improves the tensile strength of the cable body, reducing the probability of deformation during use and thus improving the overall performance of the cable body.

[0022] 2. In this application, during cable use, the cross-linked polyethylene protective layer and the raised ring have good elasticity, thereby increasing the friction between the protective layer and the outer sheath, thus reducing the probability of displacement between the protective layer and the outer sheath during use, and consequently reducing the probability of cable deformation. Furthermore, due to... Figure 2 As shown, multiple raised rings are arranged in a parallel array on the outer wall of the protective layer. These raised rings increase the surface roughness of the protective layer, thereby increasing the friction between the protective layer and the outer sheath. This further reduces the probability of displacement between the protective layer and the outer sheath, and consequently, the probability of deformation of the cable body. Furthermore, the cross-linked polyethylene material possesses excellent heat resistance, insulation, mechanical properties, and corrosion resistance, further reducing the probability of damage to the cable body during use and extending the service life of the device.

[0023] 3. In this application, the fiberglass filling layer possesses excellent tensile strength, elasticity, and dimensional stability, thereby further improving the tensile strength of the cable body and allowing it to recover its original shape after deformation, thus enhancing the overall performance of the cable body. Figure 3As shown, the anti-slip texture increases the friction between the reinforcing core and the filling layer, thereby reducing the probability of displacement between the anti-slip texture and the filling layer, and thus reducing the probability of deformation of the cable body.

[0028] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-3 As shown in the illustration, this application discloses a tensile-resistant cable, comprising a cable core 1, an insulation layer 11, a protective layer 12, an outer sheath 13, a reinforcing core 14, a filling layer 15, a convex ring 2, a connecting lug 4, and a tensile wire 41. Multiple cable cores 1 are provided, and multiple insulation layers 11 are provided and respectively sleeved on the outer walls of multiple cable cores 1. The protective layer 12 is disposed on the outer walls of multiple cable cores 1, and the outer sheath 13 is disposed on the outer wall of the protective layer 12. The reinforcing core 14 is disposed within the protective layer 12, and the filling layer 15 is disposed between the reinforcing core 14, the cable cores 1, and the protective layer 12. The reinforcing core 14, the cable cores 1, the protective layer 12, and the filling layer 15 are formed by wrapping.

[0030] When the cable body is in use, current is transmitted through multiple cable cores 1. During operation, the multiple cable cores 1 are connected by an insulation layer 11 and a filler layer 15, allowing each cable core to work independently, thereby improving the practicality of the device. Furthermore, during use, the reinforcing core 14, cable cores 1, protective layer 12, and filler layer 15 are manufactured through a wrapping process. The reinforcing core 14 improves the tensile strength of the cable body, thereby reducing the probability of deformation during use and improving the overall performance of the cable body.

[0031] Multiple raised rings 2 are arranged in a parallel array on the outer wall of the protective layer 12, and the raised rings 2 are fixed to the protective layer 12. The protective layer 12 is made of cross-linked polyethylene material, and the raised rings 2 are also made of cross-linked polyethylene material.

[0032] When the cable body is in use, the cross-linked polyethylene protective layer 12 and the raised ring 2 have good elasticity, which increases the friction between the protective layer 12 and the outer sheath 13, thereby reducing the probability of displacement of the protective layer 12 and the outer sheath 13 during use, and thus reducing the probability of deformation of the cable body. Furthermore, due to… Figure 2 As shown, multiple raised rings 2 are arranged in a parallel array on the outer wall of the protective layer 12. These multiple raised rings 2 increase the surface roughness of the protective layer 12, thereby further increasing the friction between the protective layer 12 and the outer sheath 13. This further reduces the probability of displacement between the protective layer 12 and the outer sheath 13, and consequently, the probability of deformation of the cable body. Furthermore, the cross-linked polyethylene material has good heat resistance, insulation, mechanical properties, and corrosion resistance, further reducing the probability of damage to the cable body during use and extending the service life of the device.

[0033] To reduce the probability of cable deformation, multiple anti-slip patterns 3 are arrayed on the outer wall of the reinforcing core 14, and the filling layer 15 is made of glass fiber. The glass fiber filling layer 15 has good tensile strength, elasticity, and dimensional stability, further improving the tensile strength of the cable body. It can also recover its original shape after deformation, thus improving the overall performance of the cable. Figure 3 As shown, the anti-slip texture 3 increases the friction between the reinforcing core 14 and the filling layer 15, thereby reducing the probability of displacement between the anti-slip texture 3 and the filling layer 15, and thus reducing the probability of deformation of the cable body.

[0034] Two connecting ears 4 are provided and symmetrically arranged on the outer wall of the outer skin 13. Two tensile wires 41 are provided and respectively arranged in the two connecting ears 4. The tensile wires 41 are made of galvanized soft copper wire.

[0035] The tensile wire 41, made of galvanized soft copper wire, further improves the tensile performance of the cable body. In addition, the tensile wire 41 made of galvanized soft copper wire has good flexibility. During use, the good flexibility can help the cable body to return to its original position after bending, thereby reducing the probability of the cable body deforming after bending and thus improving the performance of the cable body.

[0036] To further improve the tensile strength of the cable body, the outer sheath 13 and the connecting lug 4 are both made of nylon. The nylon outer sheath 13 and connecting lug 4 have good abrasion resistance, thus reducing the probability of damage during use and extending the service life of the device. Furthermore, the outer sheath 13 and connecting lug 4 are made of the same material, reducing the probability of resistance between the two materials and improving the overall performance of the cable body. In addition, the excellent tensile strength of nylon further enhances the tensile strength of the cable body.

[0037] To reduce the difficulty of the work for the staff, fluorescent powder is applied to the outer wall of the protective layer 12. When the outer skin 13 is damaged, the staff can observe the damage point through the fluorescent powder, thereby reducing the difficulty of repairing the outer skin 13 and thus reducing the difficulty of the staff's work.

[0038] To further reduce the probability of cable deformation, multiple anti-slip grooves 5 are arranged in a circumferential array on the outer wall of the convex ring 2. The anti-slip grooves 5 further increase the friction between the protective layer 12 and the outer sheath 13, thereby reducing the probability of displacement between the protective layer 12 and the outer sheath 13, and thus reducing the probability of cable deformation.

[0039] The working principle of the tensile-resistant cable in this embodiment is as follows: When the cable body is in use, current is transmitted through multiple cable cores 1. During operation, the multiple cable cores 1 are connected by an insulation layer 11 and a filling layer 15, allowing multiple cable cores to work independently, thereby improving the practicality of the device. Furthermore, during use, the reinforcing core 14, cable cores 1, protective layer 12, and filling layer 15 are produced by wrapping. During use, the reinforcing core 14 improves the tensile strength of the cable body, thereby reducing the probability of deformation during use and improving the overall performance of the cable body. In addition, during use, the cross-linked polyethylene material used for the protective layer 12 and the raised ring 2 has good elasticity, increasing the friction between the protective layer 12 and the outer sheath 13, thus reducing the probability of displacement between the protective layer 12 and the outer sheath 13 during use, and further reducing the probability of deformation of the cable body. Furthermore, from... Figure 2As shown, the convex rings 2 are arranged in a parallel array on the outer wall of the protective layer 12. The multiple convex rings 2 increase the surface roughness of the protective layer 12, which in turn increases the friction between the protective layer 12 and the outer sheath 13, thereby further reducing the probability of displacement between the protective layer 12 and the outer sheath 13, and further reducing the probability of deformation of the cable body.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
