Description

Technical Field

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

[0002] Connecting cables are cables with power transmission capabilities, used in harsh working environments such as construction site equipment, underground mining machinery, container transfer equipment, waste treatment plants, and railway platforms.

[0003] Currently, connecting cables still have many drawbacks in practical applications. Their function is limited, lacking communication capabilities. This is particularly problematic in underground mining machinery, where surface control systems require separate communication cables to control underground equipment, increasing the difficulty of cable installation. Furthermore, the fragility and poor insulation of optical fibers make them prone to leakage and fire after prolonged use, resulting in poor lifespan and safety performance. This is especially true in harsh working environments, where the lifespan will be further shortened, easily leading to communication interruptions and affecting equipment operation.

[0030] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0031] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0032] like Figure 1 As shown, this utility model provides a connecting cable, mainly used for power transmission in various devices. It incorporates a communication optical cable, thus performing both power transmission and communication functions. The connecting cable includes a cable body 1, an optical cable assembly 2, a grounding cable 3, and multiple cable assemblies 4, preferably three, all housed within the cable body 1. The optical cable assembly 2 is located at the center of the cable body 1 and is coaxially aligned with it. Multiple optical fibers 20 are housed within the optical cable assembly 2, effectively protecting it and preventing damage to the optical fibers 20, thereby improving the durability of the connecting cable's communication function. The multiple cable assemblies 4 are arranged around the optical cable assembly 2, uniformly symmetrical about the axis of the cable body 1. The cable body 1 is filled with a cable core filler 5, which improves the overall strength of the connecting cable, reduces the risk of damage to the cable body 1, and enhances the durability of the connecting cable.

[0033] This application combines power transmission and communication functions. Communication can be achieved immediately after the cable is installed, eliminating the need for separate communication cables. Furthermore, the cable body 1 and the cable core filler 5 effectively protect the optical cable assembly 2, improving its service life and safety performance, ensuring communication quality, and reducing the investment in engineering construction and the cost of subsequent operation and maintenance.

[0034] Furthermore, the connecting cable also includes multiple reinforcing cores 6 disposed inside the cable body 1. The multiple reinforcing cores 6 are evenly arranged with the axis of the cable body 1 as the axis of symmetry, which effectively improves the tensile strength of the connecting cable and also prevents the optical fiber 20 from being damaged due to excessive bending of the connecting cable. The reinforcing core 6 is preferably steel wire, and the surface of the reinforcing core 6 is covered with a phosphate coating to improve the corrosion resistance of the reinforcing core 6.

[0035] See Figure 1The cable assembly 4 includes a copper core 41 and an insulation layer 42 covering the copper core 41. The optical cable assembly 2 includes a loose tube 21 and a first steel sheath 22. Multiple optical fibers 20 are disposed inside the loose tube 21, and the first steel sheath 22 is fitted over the loose tube 21. The inner and outer surfaces of the first steel sheath 22 are provided with annular protrusions at intervals to improve the mechanical strength of the first steel sheath 22 and enhance the protection of the optical fiber 20 assembly.

[0036] See Figure 1 A second steel sheath 7 is provided between the cable body 1 and the cable core filler 5. The inner and outer surfaces of the second steel sheath 7 are provided with annular protrusions at intervals to improve the mechanical strength of the second steel sheath 7 and enhance the protection of the optical fiber 20 assembly.

[0037] Furthermore, the annular protrusions on the first steel sheath 22 and the second steel sheath 7 significantly enhance the adhesion between the steel sheath and the cable core filler 5, the optical cable assembly 2, and the cable body 1, ensuring that the optical cable will not detach due to insufficient friction during complex production processes, thereby stabilizing product quality. In addition, the annular protrusions increase the surface area of ​​the first steel sheath 22, promoting the formation of a surface oxide film, which can greatly slow down the corrosion rate of the steel strip during storage and transportation.

[0038] Preferably, the cable body 1 is made of polyvinyl chloride or polyethylene.
