An adaptive multi-directional anti-bending cable

Abstract

The invention discloses an adaptive multi-directional bending-resistant cable, which belongs to the field of cables. The invention arranges a bending-resistant screw sleeve between the sheath and the cable core. When the invention is subjected to bending force in any direction, it will cause When the sheath and the cable core are bent, the originally uniformly dispersed elastic rods will gradually move to the vicinity of the bending point due to their own length limitations, and gather at the bending point to jointly provide the cable core with resistance to bending. force, so that the present invention has greater bending resistance, and when the external bending force disappears, a plurality of bending elastic rods will automatically disperse, providing the sheath and cable core with resilience to restore the linear shape, making the present invention The invention restores the straight state faster and more effectively, reducing the bending damage of the cable core. In addition, when the external bending force reaches a higher strength, the bending-resistant elastic rod automatically releases gas outwards, reducing its own bending resistance. It has a certain degree of flexibility, so that the present invention can adapt to larger external force.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to an adaptive multi-directional anti-bending cable. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] Materials for wire and cable should have good mechanical properties, including tensile strength, elasticity, plasticity, hardness, toughness, fatigue strength, bending resistance, etc. Tensile strength, also known as tensile strength, refers to the maximum bearing capacity of a material under static tensile conditions, and bending resistance refers to the ability of a material to withstand bending. [0004] In the pr...

AI Technical Summary

Problems solved by technology

[0004] In the process of transportation and laying, the cable will inevitably be pulled and bent by the outside world. Therefore, the cable generally needs to have a certain degree of flexibility to adapt to the external force. However, once the external force is large, the cable will be subject to greater bending. However, the cable itself has limited bending resistance, which will cause excessive bending of the cable, resulting in cracking and damage to the internal conductive core due to bending, making the cable unable to be used in normal production
