Cable manufacturing method

Abstract

The embodiment of the invention discloses a cable manufacturing method. A PCB of a node unit is manufactured, and two ends of the PCB are provided with butt joint parts, and a node unit protector is formed on the periphery of the PCB and between the butt joint parts at two ends. Base material cable unit manufacturing comprises steps: a cable bundle comprising a signal line is manufactured, and butt joint cable cores are preserved at two ends of the cable bundle; each base material cable unit is connected with each node unit, and a cable body is formed, wherein the butt joint parts at two ends of the node unit are respectively in butt joint with the butt joint cable cores at two sides of the base material cable unit; and an outer sheath coating the cable body is formed outside the cable body. By using the cable manufactured by the method in the embodiment of the invention, the cable is able to adapt to construction scenes with harsh environment such as undermine and underground, and requirements on the cable by special environment can be met.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a method for manufacturing cables. Background technique [0002] With the rapid development of data communication technology and information technology, the performance requirements of the network for the integrated wiring system are getting higher and higher. In the current network cabling system, cables and signal cables are usually laid separately, which leads to the disadvantages of dense and disordered cables, high cable laying costs, and complicated laying construction. In a more complex or harsh environment, the cables in the integrated wiring system are not easy to deploy or the performance of communication equipment is poor. [0003] Taking the underground mining area as an example, because the terrain in the mining area is relatively tortuous, the working space is limited, and the environment such as temperature and humidity is harsh, cables and signal cables are lai...

AI Technical Summary

Problems solved by technology

However, infrared radiation or microwave radiation is easily restricted by terrain conditions such as high and low, twists and turns, turns, and bends, and is not suitable for harsh climates. The influence of climate, the false positive rate is high

Vibrating optical cables are greatly affected by the outside world, and vibrations generated by pedestrians or roads can easily cause false alarms, and cannot be used in some special terrains and environments

The cost of leaking cables is high, the construction is complicated, and false alarms are easy to occur in thunderstorms

Static induction perimeter is too expensive

Solutions such as electronic fences and power grids have certain personal hazards
