Description

Technical Field

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

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors. When laying wires and cables, a protective sheath is wrapped around the outside of the cable. The main purpose of the protective sheath is to provide protection.

[0003] Chinese Patent Publication No. CN210223627U discloses a flexible, wear-resistant cable protective sleeve, relating to the field of cable protective sleeves. The sleeve includes a flexible protective sleeve with a cable core fixedly connected to its inner wall. The flexible protective sleeve comprises a wear-resistant and corrosion-resistant layer, a sponge elastic filler, an elastic strip, a heat-resistant layer, and an insulation layer. The inner surface of the wear-resistant and corrosion-resistant layer is fixedly connected to the outer surface of the sponge elastic filler, and the elastic strip is located inside the sponge elastic filler and fixedly connected to it. This invention increases the wear resistance and corrosion resistance of the flexible protective sleeve through the wear-resistant and corrosion-resistant layer, effectively improving its service life. The sponge elastic filler and elastic strip prevent the cable core from being affected by thermal expansion and contraction under hot or cold weather conditions. The heat-resistant layer increases the high-temperature resistance of the flexible protective sleeve, preventing it from cracking and being damaged. The insulation layer prevents leakage from the cable core from affecting the surrounding environment.

[0004] The above-mentioned existing technical solutions have the following shortcomings: In use, the above technical solutions protect the cable exterior by setting a single wear-resistant and corrosion-resistant layer. However, in actual use, the wear resistance is poor. After long-term use, the surface protective layer will be severely worn, resulting in low utilization and failing to protect the cable. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a cable sheath with wear-resistant properties to solve the problem of poor wear resistance of existing cable sheaths mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable sheath with wear-resistant function, comprising an insulating sleeve disposed on the outside of the cable body;

[0007] The insulating sleeve is fitted with a silicone sheath, and a sheath body is provided outside the silicone sheath. The outer surface of the sheath body is coated with rubber coating.

[0008] Preferably, the sheath body is composed of an upper sheath and a lower sheath, which are symmetrically distributed vertically, and the material of the sheath body is polyurethane.

[0009] Preferably, grooves are provided at both ends of one side of the upper sheath, and protrusions are fixed at both ends of one side of the lower sheath.

[0010] Preferably, upper connecting blocks are fixed on both sides of the upper sheath, and lower connecting blocks are fixed on both sides of the lower sheath.

[0011] Preferably, the upper connecting block and the lower connecting block are evenly provided with fixing holes, and a positioning pin passes through the inside of the fixing hole, and a stop is threaded to the outside of the positioning pin.

[0012] Preferably, the interior of the insulating sleeve is uniformly provided with adhesive, and the adhesive is made of EAA 8290, while the insulating sleeve is made of polyethylene.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the wear-resistant cable sheath facilitates cable protection, improves the wear resistance of the cable sheath, facilitates the replacement of the wear-resistant structure, extends its service life, and facilitates the improvement of the performance of the cable sheath.

[0014] By sliding the groove and the convex groove together, the upper sheath and the lower sheath are connected. This aligns the fixing holes on the upper and lower connecting blocks. Then, the positioning pin is inserted into the fixing hole, and the upper and lower connecting blocks are fixed by threaded connection between the stop block and the positioning pin. This, in turn, fixes the upper and lower sheaths together, making it easier for the upper and lower sheaths to provide wear-resistant protection for the cable body. The upper and lower sheaths are made of polyurethane, which helps to improve the wear resistance of the cable sheath.

[0015] By applying rubber coating to the exterior of the sheath body, the rubber coating has good insulation and wear resistance, which can improve the wear resistance of the sheath body. Conversely, the positioning pin and the stop block can be separated, the positioning pin can be removed, the upper connecting block and the lower connecting block can be separated, and the convex groove can slide out from the inside of the groove, so that the upper sheath and the lower sheath can be disassembled, which facilitates the replacement of the sheath body and extends the service life of the cable sheath.

[0016] Adhesive is applied to the inside of the insulation sleeve to bond it to the cable body. After curing, a strong bond is formed, which facilitates the protection of the cable body. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0026] Example 1

[0027] To address the problem of inconvenient protection under existing cable sheaths, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 3 , Figure 5A cable sheath with wear-resistant function includes an insulating sleeve 2 disposed on the outside of the cable body 1, a silicone sheath 3 sleeved on the outside of the insulating sleeve 2, an adhesive 9 uniformly disposed inside the insulating sleeve 2, the adhesive 9 being made of EAA 8290, and the insulating sleeve 2 being made of polyethylene.

[0028] In this embodiment, during use, adhesive 9 is applied to the inside of the insulating sleeve 2 to bond the insulating sleeve 2 and the cable body 1 together. After curing, a strong bond is formed, which facilitates the protection of the cable body 1. The insulating sleeve 2 is made of polyethylene, which has excellent electrical insulation performance and low temperature resistance, thus facilitating the protection of the cable body 1. The silicone sheath 3 has good high temperature resistance and aging resistance, as well as excellent flexibility and ease of installation, which facilitates heat dissipation for the cable body 1.

[0029] Example 2

[0030] This embodiment differs from Embodiment 1 in that it utilizes the rubber coating 5 to protect the cable and improve the wear resistance of the cable sheath. Therefore, the following technical solution is disclosed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 4 Furthermore, the silicone sheath 3 is provided with a sheath body 4 on its outside. The sheath body 4 is coated with rubber coating 5. The sheath body 4 is composed of an upper sheath 401 and a lower sheath 402. The upper sheath 401 and the lower sheath 402 are symmetrically distributed vertically. The material of the sheath body 4 is polyurethane. Grooves 403 are provided at both ends of one side of the upper sheath 401. Protrusions 404 are fixed at both ends of one side of the lower sheath 402. Upper connecting blocks 6 are fixed on both sides of the upper sheath 401. Lower connecting blocks 7 are fixed on both sides of the lower sheath 402. Fixing holes are evenly provided on the upper connecting blocks 6 and the lower connecting blocks 7. A positioning pin 8 passes through the inside of the fixing hole. A stop block is threaded to the outside of the positioning pin 8.

[0031] In this embodiment, during use, the upper sheath 401 and the lower sheath 402 are connected by sliding the groove 403 and the protrusion 404, thus aligning the fixing holes on the upper connecting block 6 and the lower connecting block 7. The positioning pin 8 is then inserted into the fixing hole, and the upper connecting block 6 and the lower connecting block 7 are fixed by a threaded connection between the stop block and the positioning pin 8. This, in turn, fixes the upper sheath 401 and the lower sheath 402, facilitating wear-resistant protection of the cable body 1 by the upper sheath 401 and the lower sheath 402. The sheath 402 is made of polyurethane, which helps improve the wear resistance of the cable sheath. By applying rubber coating 5 to the outside of the sheath body 4, the rubber coating 5 has good insulation and wear resistance, which helps improve the wear resistance of the sheath body 4. Conversely, the positioning pin 8 and the stop block can be separated, the positioning pin 8 can be removed, and the upper connecting block 6 and the lower connecting block 7 can be separated, so that the protrusion 404 slides out from the inside of the groove 403, and the upper sheath 401 and the lower sheath 402 can be removed, which facilitates the replacement of the sheath body 4 and increases the service life of the cable sheath.
