Description

Technical Field

[0001] This utility model relates to the field of cable abrasion prevention, specifically to an abrasion-resistant cable protection structure. Background Technology

[0002] A cable is an electrical device consisting of one or more conductor cores, an insulation layer, a protective layer, and an outer sheath, used to transmit electrical energy, signals, or data. Most existing cables are used outdoors, and exposed cables increase wear and reduce service life. Therefore, cable protection structures with wear-resistant properties are needed. The "Cable with an Wear-Resistant Structure" disclosed in application number "202123270409.X" represents an increasingly mature technology. Its "copper shielding layer is embedded within a polyvinyl chloride wear-resistant layer, and through a polytetrafluoroethylene corrosion-resistant layer, the wear resistance of the cable's outer layer can be effectively improved, reducing damage caused by various frictions during use, and..." The copper shielding layer helps improve the cable's performance in the event of damage to the outer layer and reduces external electromagnetic interference, ensuring normal cable operation. However, this cable has the following drawbacks during use: while the PTFE (polytetrafluoroethylene) does provide abrasion resistance, the combined effect of these structures is insufficient. Therefore, a cable protection structure that significantly improves abrasion resistance and enhances practicality is necessary. Furthermore, the current cable protection structure's protective effect is not significant enough; thus, a protective structure that improves protection effectiveness and extends service life is also necessary. Utility Model Content

[0003] The present invention provides an anti-wear cable protection structure, which aims to solve the problem that the wear resistance and protection effect of existing cable protection structures are not significant enough.

[0004] To achieve the above objectives, this utility model provides an abrasion-resistant cable protection structure, including protective components; The protective component includes a bellows, with flanges fixedly connected to both the upper and lower ends of the bellows. Several telescopic springs are movably installed on the side surface of the bellows. A wear-resistant tube is provided inside the bellows, and a spiral steel strip is installed inside the wear-resistant tube. A semiconductor shielding layer is provided inside the spiral steel strip, and a filling layer is provided inside the semiconductor shielding layer. A copper conductor is provided inside the filling layer.

[0005] As a preferred embodiment of this utility model, the surface of the flange is provided with a plurality of fastening screw holes in a ring array at equal intervals, and the upper and lower ends of the plurality of telescopic springs are fixedly connected with fastening bolts, the fastening bolts being threaded into the inside of the fastening screw holes.

[0006] As a preferred embodiment of this utility model, the wear-resistant tube is provided with reinforcing ribs inside, and the reinforcing ribs are made of nylon.

[0007] As a preferred embodiment of this utility model, the inner wall of the semiconductor shielding layer is fixedly connected with a number of arc-shaped clips, and the side surface of the filling layer is provided with a number of arc-shaped slots, and the number of arc-shaped clips are all engaged inside the arc-shaped slots.

[0008] As a preferred embodiment of this utility model, the wear-resistant tube is made of polycarbonate.

[0009] In a preferred embodiment of this invention, the filling layer is made of asbestos.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. When used in cable protection structures, the corrugated tube on the cable side surface has bending and extension properties, which can initially enhance the cable's wear resistance. At the same time, the telescopic spring has a tension limiting effect, preventing excessive bending of the cable and causing wear. Combined with the wear-resistant tube made of polycarbonate material, which has good wear resistance, it can significantly enhance the wear resistance. Compared with the protection structure in the existing technology "a cable with a wear-resistant structure", this utility model can significantly enhance the wear resistance of the cable through the combination of the above structures, thereby enhancing the practicality of the cable protection structure. 2. When used in cable protection structures, the spiral steel strip installed in the inner layer of the wear-resistant tube can enhance the cable's anti-torsion effect, initially improving the protection effect, and also providing fire resistance. Combined with the semiconductor shielding layer and the asbestos filling layer, it can enhance the waterproof, fireproof, and electromagnetic interference resistance effects. Compared with the cable protection structure in the existing technology "a cable with an anti-wear structure", this utility model, through the combination of the above structures, can easily achieve the effects of fireproof, moisture-proof, anti-torsion, and electromagnetic interference resistance, thereby enhancing the protection effect of the cable and extending its service life.

During use, the corrugated tube 101 on the cable's side surface has bending and elongation properties, which initially enhances the cable's wear resistance. Simultaneously, the telescopic spring 103 has a tension limiting effect, preventing excessive bending and wear. Combined with the wear-resistant tube 104 made of polycarbonate material, which has good wear resistance, it significantly enhances the anti-wear performance and improves the practicality of the cable protection structure. Furthermore, the spiral steel strip 105 inside the wear-resistant tube 104 enhances the cable's torsion resistance, thus initially improving the protection effect and providing fire resistance. Combined with the semiconductor shielding layer 106 and the asbestos filling layer 107, it significantly enhances the waterproof, fireproof, and electromagnetic interference-resistant effects, thereby extending the cable's service life.

[0017] Please see Figures 2-5 The surface of the flange 102 is provided with a number of fastening screw holes 111 in a ring array at equal intervals.
