Description

Technical Field

[0002] 5G micro base stations are core equipment of 5G networks, providing wireless coverage within a designated area and enabling residents to enjoy the convenience of 5G networks. Due to their high frequency and significant signal attenuation, their coverage area is not as large as that of 4G, hence the name 5G micro base station.

[0003] Fiber-optic composite cable is a new type of cabling access mode that integrates optical and electrical transmission. It addresses the issues of power supply and optical communication signal transmission for equipment. With the gradual deployment of micro base stations, laying optical and electrical cables separately would double the construction pressure on the construction team. Furthermore, the landing sites of micro base stations vary, and the cabling environments differ. Therefore, composite cable cabling saves on cabling costs and conduit resources, making it a relatively advantageous cabling method. However, micro base stations contain optical modules for communication transmission, so the composite cable must be terminated to match these modules after installation. Existing composite cables often use fusion splicing or quick-connect methods for prefabrication at both ends, which cannot guarantee performance and lacks the ability to withstand harsh environments such as shock, dust, and water, posing significant potential risks for later maintenance.

[0058] In an embodiment of the present invention, an optoelectronic composite cable for 5G micro base stations is also provided. One end of the optoelectronic composite cable 500 is connected through the aviation plug assembly for optoelectronic composite cables in the above embodiment, and the other end of the optoelectronic composite cable 500 is fanned out with optical fiber 520 and wire 510 through a branch tail cable.

[0059] See Figure 10 Specifically, the branching tail cable includes a front component 321 and a rear component 322 of the brancher.

The corrugated tube has tensile and compressive strengths and is suitable for protecting the fan-out separated optical and electrical units.

[0061] In an embodiment of the present invention, the optoelectronic composite cable includes 12 optical fibers and 9 conductors. Three groups consist of 3 conductors and 4 optical fibers. The termination of the fan-out optical fibers and conductors is not further described in this invention. It can be used simultaneously for optoelectronic synchronous transmission in three micro base stations. The electrical components of the micro base station are: live, neutral, and ground; the optical components consist of one main and one backup receiver / emitter module. The optical fiber components are ordered according to international optical fiber color codes for easy wiring and connection. The cross-sectional area of ​​the conductors is determined by factors such as equipment power and transmission distance; this invention does not fix this.

[0062] In an embodiment of the present invention, the optoelectronic composite cable includes an optoelectronic composite cable, a plug assembly, a socket assembly, and a branch tail cable assembly prefabricated and connected to the end of the composite cable body. The matching of the plug and socket enables the assembly to become a complete link, forming optical and electrical synchronous transmission communication.

[0063] The optoelectronic composite cable in the above embodiments meets the integration of 12 optical and 9 electrical components. It is primarily designed for simultaneous optoelectronic synchronous transmission in three micro base stations. Component performance is fully inspected and prefabricated in the factory. It possesses technical characteristics such as optoelectronic integration, shock resistance, dust and water resistance, and high tensile strength, and can simultaneously meet the optoelectronic requirements of multiple micro base stations. While achieving advantages such as rapid installation by a single person and plug-and-play functionality, it significantly reduces construction costs and time, facilitating the rapid deployment of 5G equipment.

[0064] See Figure 12 In the embodiments of the present invention, a method for using the above-mentioned optical-electric composite cable is also provided. In harsh wiring environments, the above-mentioned aviation plug assembly is used for connection when laying the optical-electric composite cable. In the scenario of the box / light pole / base station tower where the micro base station is installed, the optical fiber and the conductor are separated by the branch tail cable when laying the optical-electric composite cable.

[0065] See Figure 13 The specific usage instructions are as follows: In harsh cabling environments, due to factors such as uncertain redundant space in cabling channels, the product requires high performance in terms of pressure resistance, tensile strength, dustproofing, and waterproofing when running through conduits. Therefore, cabling is carried out using the plug-pull and socket-pull methods of the aviation plug assembly.

[0066] For specific usage instructions, in scenarios such as the enclosure / light pole / base station tower where micro base stations are installed, since the equipment is directly connected, it is recommended to use the optoelectronic separation branch tail cable method and pull the corrugated pipe for wiring.

[0067] In use, for the plug assembly, the composite cable 500 is stripped and the composite cable is inserted into each part in the following order: plug tail sleeve 160, pressure ring fixing nut 150, rivet pressure ring 140, and plug body 130. (To be determined)

[0068] After assembling the wires in the plug photoelectric transmission component 122, the metal needle 410 is embedded into the plug photoelectric transmission component 122 by riveting. The plug photoelectric transmission component 122 is then snapped into the plug insulating fastener 123, and the plug insulating fastener spring 121 is used to hold and fix the plug photoelectric transmission component 122.

[0069] The plug assembly is made by threading 12 colored optical fibers into the multi-core plastic ferrule 431 in chromatographic order, according to the male-female correspondence, that is, the plug uses the female connector assembly and the socket uses the male connector assembly, and vice versa; the male connector fixing part 3451 and the female connector fixing part 3452, the fiber tube 434, and the flat spring 433 are assembled, and then the surface of the multi-core ferrule is ground and polished using a multi-core grinding process.

[0070] The plug assembly consists of the photoelectric unit in the plug photoelectric transmission component 122. The polished multi-core optical component is inserted into the central optical port of the plug photoelectric transmission component 122 and secured with the fixing tailpiece 432. The wires are soldered using an electric welding process. Heat shrink tubing is used for protection at the solder joints. This completes the fabrication of the plug core component 120.

[0071] For the plug assembly, the plug body 130 and the plug core assembly 120 are threaded together and fixed. At this point, the position of the crimping ring 140 is clearly defined. The threaded crimping process is then performed according to this position. Subsequently, the crimping ring fixing nut 150 is tightened to the rear thread of the metal body 130 for secure fastening. The tail sleeve 160 is then fitted on, and the plug dust cap 110 is placed on top, completing the prefabrication of the overall plug assembly. Additionally, thread-locking adhesive can be used at each thread to reinforce the overall fastening.

[0072] The stripping of the composite cable 500 in the socket assembly can be adjusted according to the arrangement distance of the socket assembly. This example does not specify the requirements. The optical transmission component 224 of the socket has a slightly adjusted manufacturing process due to the insulation component being divided into two parts. The example is as follows: First, the copper guide pin seat 420 is crimped to the rear component 2242 of the socket insulation component. Then, the entire assembly is pushed into the front component 2241 of the socket insulation component according to the principle of "groove alignment." Finally, the entire assembly is fixed to the socket insulation fixing component 223 using the socket insulation component fixing spring 225. Following the manufacturing process of the multi-core plug assembly, the core socket component 220 is assembled. Subsequent manufacturing processes can be referenced from the plug assembly.

[0073] For the branch tail cable assembly, firstly, according to the actual required distance, strip the composite cable 500mm and perform photoelectric separation according to the principle of 4 optical and 3 electrical components per group. Then, insert the adhesive heat shrink tubing 330 and the brancher rear component 322.

[0074] To further protect the optoelectronic unit, the conductors can be protected with insulating flame-retardant polyethylene sheaths, and the optical fibers can be protected with armored sheaths. Each sheath is fixed in the corresponding hole of the front component 321 of the splitter using glue and crimping. Then, the separated conductors and optical fibers are fitted into their respective sheaths; there are three sets in total. Next, the rear component 322 of the splitter is rotated and tightened, and the threaded part of the rear component 322 is crimped together with the composite cable 500. Finally, heat-shrink tubing 330 is used for protection. The overall structure is now complete. The branched-out optical fibers can be manufactured according to industry standards for long-distance optical cable assemblies. The conductors can be crimped with terminals according to customer requirements; this example does not provide detailed explanations. Finally, the tail cable protection unit 310, matching the front component 321 of the splitter, is used to protect the fan-out portion. The tail cable protection unit 310 can be pulled during traction.

[0075] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
