Abstract
The invention discloses a self-adaptive multi-directional anti-bending cable, and belongs to the field of cables. An anti-bending lead screw sleeve is arranged between a sheath and a cable core, when the self-adaptive multi-directional anti-bending cable is subjected to bending force in any direction, and the sheath and the cable core are bent, a plurality of anti-bending elastic rods which are originally uniformly and dispersedly arranged are limited by the lengths of the anti-bending elastic rods, the plurality of anti-bending elastic rods gradually move near the bending point and are gathered at the bending point to jointly provide acting force for the cable core to resist bending, so that the cable has relatively high bending resistance, and when external bending force disappears, the plurality of anti-bending elastic rods are automatically dispersed to provide resilience force for the sheath and the cable core to recover a linear shape, and therefore, the linear state can be recovered more quickly and effectively, and the bending damage degree of the cable core can be reduced. In addition, when external bending force reaches a relatively high degree, the anti-bending elastic rods automatically release gas outwards, so that the anti-bending performance of the anti-bending elastic rods is reduced, the anti-bending elastic rods have certain flexibility, and the cable adapts to relatively large external acting 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...
