Flat high-speed cable production method and products thereof

Abstract

A flat high-speed cable manufacturing method and a flat high-speed cable manufactured by using the method. The manufacturing method comprises the following steps: 1) manufacture of a semi-finished flat high-speed cable to be processed: 1.1) pressing middle layers, and 1.2) forming the semi-finished flat high-speed cable; 2) cable division: arranging a cable diving apparatus, and dividing the semi-finished flat high-speed cable into two halves of cable symmetrical to each other; 3) cable combination: arranging a cable combination apparatus, and combining the two halves of cable symmetrical to each other into a circular cable split symmetrically; and 4) cable stranding: stranding the combined circular cable to form a flat high-speed cable stranded by two halves of cable. The manufacturing method is reliable in principle, high in efficiency and low in cost. By means of the cable dividing apparatus and the cable combining apparatus, the flat high-speed cable with high performance and high quality is manufactured by using steps of cable arrangement, division, combination and stranding and the like.

Description

technical field [0001] The invention relates to a cable preparation technology, in particular to a method for preparing a flat high-speed cable and a flat high-speed cable implementing the method. Background technique [0002] The flat high-speed cables currently on the market use a single wire to be directly twisted when they are twisted into cables. The single wire of the flat cable produces a stress response due to the twisting force of the twisted wire, resulting in flatness in the flat high-speed cable. High-speed wire pairs (high-speed flat signal pairs) are prone to damage due to stress or lead to poor electrical performance, such as poor delay and attenuation. [0003] In addition, when multiple flat high-speed wire pairs are combined into a cable, the structural factors are likely to cause out-of-round twisting, and the flat wire pairs are easy to stretch and shift when they are bent. Traditional flat high-speed cables are filled with cotton yarn, PP rope, PE strip...

AI Technical Summary

Problems solved by technology

[0002] The flat high-speed cables currently on the market use a single wire to be directly twisted when they are twisted into cables. The single wire of the flat cable produces a stress response due to the twisting force of the twisted wire, resulting in flatness in the flat high-speed cable. High-speed line pairs (high-speed flat signal pairs) are prone to damage due to stress or lead to poor electrical performance, such as poor delay, attenuation, etc.

[0003] In addition, when multiple flat high-speed wire pairs are combined into a cable, the structural factors are likely to cause twisting out of circle, and the flat wire pairs are easy to stretch and shift when bending.

Traditional flat high-speed cables are filled with cotton yarn, PP rope, PE strips, PVC strips and other similar materials when they are assembled into cables. Although the roundness of twisted wires can be improved, the fillers are easy to shift and cause serious filling defects. Affects the quality of flat high-speed cables

[0004] Flat high-speed cables prepared by traditional methods have poor stability, roundness cannot be guaranteed, and softness is low, and the bending radius of flat high-speed cables cannot be effectively reduced, and it is difficult to adapt to frequent bending, etc.
