Super-flexible communication cable in 5G industrial internet digital system and manufacturing method

Abstract

The invention discloses a super-flexible communication cable in a 5G industrial internet digital system and a manufacturing method. An upper side of a conductor structure is formed by twisting a tin-plated oxygen-free copper conductor with the purity of 99.99% and 250D nylon wires. The maximum value of the direct-current resistance is 14 ohm / 100 m, and a physical foaming fluorinated ethylene propylene insulating layer is used on an upper side of an insulating structure such that the dielectric constant of a cable core is reduced, the requirement of low attenuation of signal transmission is met, and the transmission rate of the cable core is improved. The invention relates to the technical field of communication cables. The invention discloses the super-flexible communication cable in the 5G industrial internet digital system and the manufacturing method. In order to improve the electromagnetic compatibility, a cable product adopts a form of extruding a semi-conductive surface insulating layer on the shielding structure; the manufacturing method is completed by using a one-step method, that is, four signal line pairs extrude a semi-conductive shielding material and a sheath materialsynchronously by using a special die such that a pair-twisting and longitudinal-wrapping aluminum foil process and a cabling process are reduced, two production processes are reduced, and the processcost is reduced.

Description

technical field [0001] The invention relates to the technical field of communication cables, in particular to an ultra-flexible communication cable and a manufacturing method in a 5G industrial Internet digital system. Background technique [0002] With the rapid development of mobile communications, global users' demand for mobile data is skyrocketing. It is estimated that by 2021, the world will officially enter the 5G era. The overall transformation trend of 5G networks is to move radio frequency devices closer to end users to improve coverage and speed up data transmission. Due to the construction limitations of traditional base stations, the solution to improve coverage is to deploy more small base stations. Therefore, the arrival of 5G will really drive the explosive growth of small base stations. The domestic data center design specification GB50174-2017 stipulates that the level of data services undertaken The system should use twisted-pair cables of Category 6A and...

In addition, in order to reduce the influence of the signal crosstalk between the wire pairs, the traditional data cable adopts a small pitch between the four pairs of wire pairs during design, and a certain pitch difference is formed between the pitches of the four pairs of wires. The pitches are respectively 9.95mm, 12.1mm, 15.3mm, 19.08mm, the smaller the pitch, the greater the twist rate, and the corresponding increase in material cost
