Description

Technical Field

[0001] The present invention relates to the technical field of coaxial cables, and in particular to a 5G coaxial cable manufacturing process. Background Art

[0002] Coaxial cable is a type of electrical wire and signal transmission line, generally made of four layers of material: the innermost is a conductive copper wire, the outside of the wire is surrounded by a layer of plastic (used as an insulator, dielectric), the outside of the insulator is covered with a thin mesh conductor (generally copper or alloy), and then the outside of the conductor is the outermost layer of insulating material as the outer sheath.

[0003] Coaxial cable can be used to transmit analog and digital signals and is suitable for a wide variety of applications. Its main disadvantage is that it cannot withstand tangling, pressure and severe bending, which will damage the cable structure and prevent signal transmission. In addition, the frequency of maintenance and replacement is high, resulting in higher costs.

[0004] The reason was found to be that most coaxial cables are not clear and standardized in the specific content of the manufacturing process during the production process, which is one of the important reasons why the shortcomings of coaxial cables that could have met the performance requirements are magnified. However, the existing technology does not have a comprehensive, specific and more detailed method to solve the problem of manufacturing process.

[0005] Based on the above reasons, the present invention designs a 5G coaxial cable manufacturing process. By refining and clarifying the whole process of coaxial cable manufacturing, the high satisfaction of the preparation process and the technical parameters of the finished product is guaranteed, the subsequent maintenance and replacement costs are reduced, and the use of coaxial cables is more stable and the cost is more controllable. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a 5G coaxial cable manufacturing process, which refines and clarifies the whole process of the coaxial cable manufacturing process, ensures the high satisfaction of the preparation process and the technical parameters of the finished product, reduces the subsequent maintenance and replacement costs, and makes the use of the coaxial cable more stable and the cost more controllable.

[0007] In order to achieve the above object, the present invention provides a 5G coaxial cable manufacturing process, comprising the following steps: S1, Cable Processing: S1-1, after winding the cable, the connector ends at both ends of the cable are stripped to expose the internal conductors. The connector ends include SMA connectors and RPTNC connectors; S1-2, cutting the cables into required lengths according to design requirements; S2, Antenna Manufacturing: S2-1, solder a small amount of tin on one end of the built-in lead, and then solder it to the conductors exposed at both ends of the cable after stripping; S2-2, test the solder joints to ensure that their electrical and mechanical properties meet the requirements; S2-3, inserting the heat shrink tubing, the single shielding tubing and the connector into the connector ends of both ends of the cable in sequence; S2-4, after preparation, crimp both ends of the cable at the same time; S3, performance test: Test the antenna’s gain, directivity, and standing wave ratio, and optimize and adjust the antenna based on the test results to ensure that it meets the needs of 5G communications.

[0008] The solder joints tested in S2-2 include conductivity, stability and low loss characteristics.

[0009] The stripping process in S1-1 includes: stripping of the conductor, single shielding sleeve, and outer insulation layer of the SMA head-end cable and the RPTNC head-end cable respectively in three layers; Each layer of processing includes the line head length and the knife value width. The line head length is the distance from the stripping end to the end, and the knife value width is the stripping width, specifically: The first layer: single shielding sleeve; the second layer: conductor; the third layer: outer insulation layer; When using SMA connector: The thread length of the first layer is 4mm, and the knife width is 2.7mm; The thread length of the second layer is 2.5mm, and the knife width is 1.0mm; The thread length of the third layer is 13.5mm, and the knife width is 4mm; When using an RPTNC head: The thread length of the first layer is 6.5mm, and the knife width is 2.8mm; The thread length of the second layer is 4.0mm, and the knife width is 1.0mm; The thread length of the third layer is 17.5mm and the knife width is 4mm.

[0010] After winding in S1-1, the cables need to be bound into a circular shape.

[0011] The length of the heat shrink tubing is 25mm.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention explains the specific steps of each link in the coaxial cable processing process from beginning to end, specifically specifies the number of layers and stripping parameters of the conductor, single shielding sleeve and external insulation layer in the coaxial cable, determines the welding process and welding requirements, and limits the requirement to crimp different connectors at both ends of the coaxial cable at the same time, thereby ensuring the stability of various coaxial cable products, improving the reliability of coaxial cable applications, and reducing maintenance costs.
