Abstract
Description
Technical Field
[0001] This utility model relates to the field of nylon cable technology, specifically to a tear-resistant nylon cable. Background Technology
[0002] Nylon cables are high-performance cables with excellent electrical properties, high-temperature resistance, and low-temperature resistance, making them widely used in various fields and a common type of cable.
[0003] Currently, nylon cables require constant movement, twisting, and placement during installation, making them susceptible to tearing and stretching from the outside. They are also subject to external pulling during operation. However, the tear resistance of current nylon cables is relatively poor, which can easily lead to breakage, especially of the internal conductors. Once the cable tears, it is highly likely to cause a fire, resulting in loss of life and property and causing considerable inconvenience. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings and defects of existing technologies by providing a tear-resistant nylon cable. This nylon cable not only effectively increases its tear resistance by adding a nylon skeleton and a thick-diameter steel wire in the middle, but also adds a tear-resistant composite tear-resistant layer on the outer layer to further enhance its tear resistance, thereby ensuring the safety of the nylon cable during installation and operation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tear-resistant nylon cable, comprising a nylon skeleton 2 and conductors 3, wherein a plurality of conductors 3 are twisted together on the outer layer of the nylon skeleton 2, the interior of the nylon skeleton 2 is provided with a centrally thick-diameter steel wire 1, and the outer layer of the plurality of conductors 3 is covered with an outer nylon layer 4, and a composite tear-resistant layer 5 is provided on the outer side of the outer nylon layer 4, and a filler layer 7 is filled between the nylon skeleton 2 and the outer nylon layer 4, and the filler layer 7 wraps around the plurality of conductors 3.
[0006] Furthermore, the outer layer of the composite tear-resistant layer 5 is provided with a waterproof layer 6 that has a waterproof effect.
[0007] Furthermore, the composite tear-resistant layer 5 includes a glass fiber layer 51, which is attached to the outer layer of the outer nylon layer 4. The outer layer of the glass fiber layer 51 is provided with a polymer polyester layer 52, and fine diameter steel wires 53 are equidistantly distributed inside the polymer polyester layer 52. The outer layer of the polymer polyester layer 52 is covered with a polyester fiber layer 54, and a TPU layer 55 is attached to the outer layer of the polyester fiber layer 54.
[0008] Furthermore, the glass fiber layer 51 is formed by interweaving fiber transverse ribs 51-1 and fiber longitudinal ribs 51-2.
[0009] Furthermore, the outer side of the nylon skeleton 2 is recessed inward to form a plurality of conductor mounting grooves 201, and the plurality of conductor mounting grooves 201 are in a twisted state.
[0010] Furthermore, the centrally located thicker diameter steel wire 1 is positioned at the center of the nylon skeleton 2.
[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This nylon cable not only effectively increases its tear resistance by adding a nylon skeleton and a thick-diameter steel wire in the middle, but also adds a tear-resistant composite tear-resistant layer on the outer layer, further enhancing the tear resistance of this nylon cable, thereby ensuring the safety of this nylon cable during installation and operation.

[0019] See Figures 1-5As shown, the technical solution adopted in this specific embodiment is as follows: it includes a nylon skeleton 2 and conductors 3. Several conductors 3 are twisted together on the outer layer of the nylon skeleton 2. The interior of the nylon skeleton 2 is provided with a steel wire 1 with a central diameter. The outer layer of several conductors 3 is covered with an outer nylon layer 4. A composite tear-resistant layer 5 is provided on the outside of the outer nylon layer 4. A filling layer 7 is filled between the nylon skeleton 2 and the outer nylon layer 4, and the filling layer 7 wraps around several conductors 3.
[0020] More specifically, the outer layer of the composite tear-resistant layer 5 is provided with a waterproof layer 6 that has a waterproof effect.
[0021] More specifically, the composite tear-resistant layer 5 includes a glass fiber layer 51, which is attached to the outer layer of the outer nylon layer 4. A polymer polyester layer 52 is provided outside the glass fiber layer 51, and fine-diameter steel wires 53 are threaded evenly distributed within the polymer polyester layer 52. A polyester fiber layer 54 is wrapped around the polymer polyester layer 52, and a TPU layer 55 is bonded to the outer layer of the polyester fiber layer 54. Both the glass fiber layer 51 and the polyester fiber layer 54 have high strength, which increases the tear resistance of the nylon cable. The fine-diameter steel wires 53 within the polymer polyester layer 52 further increase the tear resistance of the cable. An additional TPU layer 55 is added outside the polyester fiber layer 54. This TPU layer 55 not only has a certain degree of tear resistance but also good corrosion resistance and toughness.
[0022] More specifically, the glass fiber layer 51 is formed by interweaving transverse fiber ribs 51-1 and longitudinal fiber ribs 51-2. By interweaving transverse fiber ribs 51-1 and longitudinal fiber ribs 51-2 to form the glass fiber layer 51, the tear resistance of the glass fiber layer 51 in both the transverse and longitudinal directions can be guaranteed.
[0023] More specifically, the outer side of the nylon skeleton 2 is recessed inward to form several conductor mounting grooves 201, and these grooves are twisted together. The conductor mounting grooves 201 are used to mount the conductors 3 inside them, which can prevent the conductors 3 from loosening and increase the stability of the conductors 3 in this cable.
[0024] More specifically, the central thick-diameter steel wire 1 is located at the center of the nylon skeleton 2. The central thick-diameter steel wire 1 is not in contact with the conductor 3 through the nylon skeleton 2, and the central thick-diameter steel wire 1 can increase the tear resistance of the nylon skeleton 2, thereby increasing the overall tear resistance of the cable.
[0025] The working principle of this utility model is as follows: The conductor mounting groove 201 on the nylon skeleton 2 in this nylon cable facilitates the stranding and installation of the conductor 3. The central thick-diameter steel wire 1 located in the middle of the nylon skeleton 2 provides sufficient tear resistance to the nylon skeleton 2. The nylon skeleton 2 can isolate the central thick-diameter steel wire 1 from the conductor 3, ensuring that the performance of the conductor 3 is not affected by the central thick-diameter steel wire 1. An outer nylon layer 4 is wrapped around several conductors 3, and the outer nylon layer 4 is wrapped by a composite tear-resistant layer 5. The tear resistance of this nylon cable is further increased by the glass fiber layer 51, the fine-diameter steel wire 53 and the polyester fiber layer 54. The outermost TPU layer 55 and the waterproof layer 6 can increase the waterproof, corrosion-resistant and wear-resistant properties of this nylon cable.
[0026] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
