Technical Field

[0002] Special cables refer to cables used in specific application scenarios or with special functions, which have characteristics such as high temperature resistance, corrosion resistance, and waterproofness under special environments.

[0003] The environment in which special cables are used is relatively special. In the existing technology, during the transportation and transfer of special cables in this environment, the outer surface of the cable has a large contact area with the ground, which will cause greater friction with the ground or the installation site. Under the action of friction, the outer surface of the cable is prone to wear, affecting its service life. Utility Model Content

[0006] The cable body includes an outer sheath provided on the outermost portion, wherein a plurality of raised rings are provided on the outer surface of the outer sheath at intervals, wherein the raised rings include a raised portion integrally provided on the outer sheath and an elastic ring embedded in the raised portion;

[0007] The raised ring reduces the area of ​​the outer sheath in contact with the ground.

[0009] As a preferred embodiment of the above technical solution, the outer sheath is provided with an insulating layer 2 and a filling layer in sequence.

The tensile members are nylon ropes, which are ropes made of nylon fibers, braided or roped. Nylon ropes are soft and flexible, easy to handle, and suitable for use in various complex environments. Nylon fibers have high tensile strength, which greatly enhances the tensile performance of the cable.

[0011] As a preferred embodiment of the above technical solution, the cable body further includes a plurality of cable cores embedded in the filling layer.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 2 、 Figure 3 As shown, Figure 2 Shown is an external schematic diagram of a cable in an embodiment; Figure 3 Shown is a schematic structural diagram of the raised ring in the embodiment;

[0023] The device includes:

[0024] The cable body includes an outer sheath 20 disposed on the outermost portion. A plurality of raised rings 21 are spaced apart on the outer surface of the outer sheath 20. The raised rings 21 include a raised portion 211 integrally provided on the outer sheath 20 and an elastic ring 212 embedded in the raised portion 211.

[0025] The raised ring 21 reduces the area of ​​the outer sheath 20 in contact with the ground.

[0026] The raised rings 21 are evenly spaced on the outer surface of the outer sheath 20. When the special cable is transported and transferred in a relatively special environment, the raised rings 21 have a certain thickness, which can reduce the contact area between the outside of the cable and the ground, thereby reducing the friction between the cable body and the ground or the installation location, avoiding wear on the outer surface of the cable, ensuring its normal use, and extending its service life.

[0027] Specifically, the raised portion 211 includes a raised cavity, and the elastic ring 212 fills and is embedded in the cavity. The cross-sectional shape of the elastic ring 212 matches the cavity. Since the elastic ring 212 has a certain elasticity, when the surface of the cable body is squeezed, it can buffer the pressure through its own deformation, thereby protecting the outer sheath 20 and preventing it from cracking or breaking under pressure.

[0028] At the same time, the provided raised ring 21 can also buffer the tension through its own deformation when the cable body is subjected to tension, thereby improving the tensile and pressure resistance of the cable body.

[0029] like Figure 1 As shown, Figure 1 Shown is a schematic diagram of the internal structure of the cable in the embodiment.

[0030] The outer sheath 20 is provided with an insulating layer 15 and a filling layer 13 in sequence, and a plurality of tensile members 14 are embedded in the filling layer 13;

[0031] The cable body further comprises a plurality of cable cores 1 embedded in the filling layer 13, and an insulating layer 11 and an inner sheath 12 are sequentially arranged on the outside of each cable core 1;

[0032] Specifically, in this embodiment, the number of the cable core 1 and the tensile member 14 is set to three, and they are evenly spaced and arranged in the circumferential direction;

[0033] The first insulation layer 11 and the inner sheath 12 play a protective role on the cable core 1. The second insulation layer 15 and the outer sheath 20 further play a protective role on this basis. The filling layer 13 plays a supporting role, and the tensile member 14 plays an anti-stretching role.

[0034] The inner sheath 12 and the outer sheath 20 are both elastic rubber sheaths, which have a certain elasticity and can increase the strength of the cable and improve its tensile resistance. The first insulating layer 11 and the second insulating layer 15 are both made of cross-linked tetrafluoroethylene, which has excellent insulation properties, good mechanical strength and wear resistance, and can withstand a certain degree of tension and compression.

[0035] The filling layer 13 is made of hard silicone material, which has a certain toughness and can be deformed when squeezed. When the cable is bent, it can quickly recover.

[0036] The tensile member 14 is a nylon rope, which is a rope made of nylon fiber braid or rope. The nylon rope is soft and flexible, easy to operate and handle, and suitable for use in various complex environments. Nylon fiber has high tensile strength, which greatly enhances the tensile performance of the cable.

[0037] Working Principle: The utility model provides a raised ring 21. When the special cable is transported and transferred in a relatively special environment, the raised ring 21 has a certain thickness, which can reduce the contact area between the outer part of the cable and the ground, thereby reducing the friction between the cable body and the ground or the installation place, avoiding wear on the outer surface of the cable, ensuring its normal use, and extending its service life.

[0038] The utility model provides a rope tensile member 14 made of nylon fiber braid or rope, which is soft and flexible, easy to operate and handle, and suitable for use in various complex environments. The tensile member 14 has high tensile strength, thereby greatly enhancing the tensile performance of the cable.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
