Data cable, cable twisting machine and twisting fabrication method of data cable

Abstract

The invention discloses a data cable, a cable twisting machine and a twisting fabrication method of the data cable. By improving equipment, three processes of twisting, aluminum foil dragging and wrapping and re-twisting are completed in one process, the time and the space are saved, and the production efficiency is improved. The data cable, particularly a re-twisted line of the data bus cable fabricated by the method is smooth in twisting, and subsequent fabrication is facilitated. In the data cable, particularly the data bus cable fabricated by the method, an insulation layer and a sheath layer of the cable are improved, the mass and the thickness of the cable are reduced by dual insulation layers made of a specially-selected material, the cable transmission characteristic is improved, and the cable has the advantages of more wear resistance, scraping resistance, weather resistance, oil resistance and better mechanical strength by the dual sheath layers made of a specially-selected material.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a data cable, a cable twisting machine and a twisting preparation method of the data cable. Background technique [0002] At present, the insulation and sheathing of cables in the automotive industry are mainly made of polyvinyl chloride, which is relatively simple to manufacture and low in cost. However, due to the simple process structure, large proportion of materials, large dielectric loss, etc., the product is relatively single-purpose, unable to achieve integrated use, heavy cables, and weak information transmission performance. At present, all walks of life are demanding for intelligent manufacturing. The transmission requirements of various systems for information collection, analysis, and feedback in production are getting higher and higher, and the required speed is getting faster and faster. Ordinary cable materials and structures have be...

Problems solved by technology

However, due to the simple process structure, large proportion of materials, large dielectric loss, etc., the product is relatively single-purpose, unable to achieve integrated use, heavy cables, and weak information transmission performance. At present, all walks of life are demanding for intelligent manufacturing. The transmission requirements of various systems for information collection, analysis, and feedback in production are getting higher and higher, and the required speed is getting faster and faster

Ordinary cable materials and structures can no longer meet its use requirements

[0003] The process of traditional multi-bus cable manufacturing internal stranding is twisting, wrapping, and cabling, which requires three processes to realize. Not only the production efficiency is low, but also the structural stability of the wire is poor after multiple processes. The internal structure is loose, and the overall outer diameter is large

[0004] Traditional cable sheaths are all made of a single material. Although manufacturing saves time and effort, the overall performance of the cable is very limited and cannot cope with harsh use conditions and environments.

In addition, due to the limitation of processing cost and the process design of the cable itself, it is impossible to realize the wide application of superior materials
