[0046] like Figure 1 , Figure 2 and Figure 3As shown in the figure, this embodiment discloses a composite communication cable for a high-speed maglev dedicated radio base station. This composite communication cable includes a cable body 1, a protective layer 2, a limiting protection block 3, and a load-bearing hook 4. The protective layer 2 covers the cable body 1 and includes an inner sheath 21, a metal armor layer 22, and an outer sheath 23. The inner sheath 21 covers the cable body 1, the metal armor layer 22 covers the inner sheath 21, and the outer sheath 23 covers the metal armor layer 22. The protective layer 2 provides protection. By sequentially covering the cable body 1 with the inner sheath 21, the metal armor layer 22, and the outer sheath 23, the protective effect of the cable body 1 is greatly improved, effectively preventing armor weathering. This effectively solves problems such as communication obstruction between devices and insufficient cable life caused by signal cable faults in base stations, effectively reducing the time cost of fault diagnosis and the manpower consumption of equipment maintenance, and significantly improving the stability of equipment operation.

[0047] The protective layer 2 passes through and is connected to the limiting protection block 3. The limiting protection block 3 is used to connect the protective layer 2 and the cable body 1, thereby fixing the cable body 1 and effectively preventing the cable body 1 from shifting due to external force or its own weight, which greatly improves the safety and stability of the composite communication cable for high-speed maglev dedicated radio base stations.

[0048] One end of the load-bearing hook 4 is connected to the outer surface of the protective layer 2, and the other end of the load-bearing hook 4 has a hook portion 41 for suspension. During installation, the load-bearing hook 4 is suspended from the pole through the hook portion 41, thereby effectively reducing the stress on the joints on the cable body 1.

[0049] The high-speed maglev dedicated radio base station composite communication cable of this embodiment primarily supports the stable operation of the Shanghai line and improves system maintenance efficiency. It enhances the quality of communication cable equipment for the Shanghai Maglev Demonstration Line's onboard operation control system, improves maintenance efficiency, and effectively guarantees the long-term continuous operation of the Shanghai Maglev Demonstration Line. It maximizes product compatibility and reliability, reduces the difficulty of maintenance for personnel working at heights, and improves maintenance efficiency. It can be used in all radio base stations of the Shanghai line's operation control system, and fault display functions can be gradually added in later use to provide more complete and convenient diagnostic tools for maintenance and testing, significantly saving personnel costs and improving equipment availability.

[0050] In this embodiment, the cable body 1 includes a wire core 11, a first interface 12, and a second interface 13. The first interface 12 and the second interface 13 are respectively connected to the two ends of the wire core 11, and the inner sheath 21 covers the wire core 11. The first interface 12 and the second interface 13 are respectively used to connect to the BSC and the BST, and the cable body 1 is used to transmit 24V, 3.5A current to the BST.

[0051] Specifically, core 11 is a full-spectrum twisted-pair unit cable core containing 12 pairs of twisted wires with a conductor cross-section of 0.25mm. The first interface 12 is a D-type 25-pin interface, connected to the BSC; the second interface 13 is a round 66-pin interface, connected to the BST. The cable body 1 also includes a Glencore connector 14, which is mounted on core 11.

[0052] The inner sheath 21 is a three-layer polyethylene or polyvinyl chloride film tape that is overlapped and wrapped around the core 11 to enhance insulation performance, ensure safety and stability, and improve mechanical protection.

[0053] A double-sided plastic-coated aluminum strip is longitudinally wrapped between the inner sheath 21 and the wire core 11. The double-sided plastic-coated aluminum strip plays a shielding role, further improving safety and stability.

[0054] The metal armor layer 22 includes a steel mesh layer and an armor layer. The steel mesh layer is longitudinally wrapped around the outer surface of the inner sheath 21, and the armor layer is cast onto the steel mesh layer. There is one steel mesh layer, and the thickness of the steel mesh layer is 0.15-0.2 mm. A 0.15-0.2 mm steel mesh layer is longitudinally wrapped around the inner sheath 21, and an anti-corrosion mixture is cast to form the armor layer. Thus, the metal armor layer 22 covers the inner sheath 21. The inner sheath 21 can effectively prevent armor weathering, effectively solve problems such as communication obstruction between equipment and insufficient cable life caused by signal cable faults in base stations, effectively reduce the time cost of fault diagnosis and the manpower consumption of equipment maintenance, and significantly improve the stability of equipment operation.

[0055] The outer protective layer 23 has a thickness of 1.4–2.4 mm. The outer protective layer 23 is made of polyethylene or polyvinyl chloride. The outer protective layer 23 provides protection, has good performance, and is low in cost.

[0056] The load-bearing hook 4 is close to the second interface 13 and far away from the first interface 12. The hook part 41 of the load-bearing hook 4 is suspended on the pole, which can greatly reduce the stress on the second interface 13 and greatly improve the safety and stability of the composite communication cable for high-speed maglev dedicated radio base station.

[0057] The connection between the load-bearing hook 4 and the protective layer 2 is covered with a heat-shrinkable protective sleeve 5. The heat-shrinkable protective sleeve 5 can effectively strengthen the connection between the load-bearing hook 4 and the protective layer 2, resulting in high stability and ease of use.

[0058] The limiting protection block 3 includes a block body 31, a clamping member 32, and a mounting member 33. The block body 31 has a through hole 311, a clamping hole 312, and a connecting hole 313. The cable body 1 and the protective layer 2 both pass through the through hole 311. The clamping member 32 is detachably connected to the clamping hole 312 and presses against the protective layer 2, thereby restricting the protective layer 2 and the cable body 1 onto the block body 31. The mounting member 33 is connected to the block body 31 and is used for external connection. After the cable body 1 and the protective layer 2 pass through the through hole 311, the clamping member 32 is connected to the clamping hole 312 to clamp the protective layer 2 and the cable body 1, thereby fixing the cable body 1 and effectively preventing the cable body 1 from shifting due to external force or its own weight, greatly improving the safety and stability of the composite communication cable for high-speed maglev dedicated radio base stations. At the same time, the mounting member 33 is connected to the connecting hole 313 and is used for connection to external structures, thereby fixing the limiting protection block 3.

[0059] In this embodiment, the limiting protection block 3 has dimensions of 150*80*40 mm (length*width*height) to prevent the cable from shifting due to external force or its own weight. Two clamping members 32 are used, located on both sides of the block body 31 and near the ends of the through hole 311, thereby clamping and fixing the through-hole protective layer 2 and the cable body 1 with high stability. Multiple connecting holes 313 are used, and their specific locations are not limited.

[0060] The high-speed maglev dedicated radio base station composite communication cable also includes a protective cover 6, which is connected to the protective layer 2 and / or the cable body 1 via a connecting wire. The protective cover 6 serves to cover and protect the cable.

[0061] The sealed connector is used to seal the cable inlet and outlet of the control box after the first interface 12 of the cable body 1 passes through the base station control box, and to fix the position of the cable.

[0062] When using the high-speed maglev dedicated radio base station composite communication cable of this embodiment, firstly, insert the first interface 12 of the composite cable into the base station from the upper cable hole of the RBS base station; then, cover the mounting hole with the lifting block and tighten the lifting block screws, and fix the lifting wire fixing ring to the base station; at the same time, attach the antenna assembly and hook the load-bearing hook 4 to the antenna assembly's mast assembly; then connect the circular connector of the second interface 13 to the BST interface; then, lead the first interface 12 out from the lower cable hole of the RBS base station, insert it into the base station control box, and tighten the sealing connector; then, insert the connector of the first interface 12 into the BSC shell and connect it to the BSC interface; finally, power on and check the base station's operation.
