Spiral correction type anti-bending cable

Abstract

The invention discloses a spiral correction type anti-bending cable, which belongs to the field of cables. A spiral correction sleeve is arranged between a cable core and an outer sheath, when the spiral correction type anti-bending cable is subjected to a bending acting force, a spiral spring rod moves towards two sides along a bending point, and a bending state with two dense ends and a dispersed middle is presented; on the basis of the bending resistance of the cable core and the outer sheath, the bending resistance of the cable core is further provided through the deformation resistance of the spiral spring rod, so that the cable core can be quickly recovered to a linear state through the elasticity of the spiral spring rod after being bent, and when the cable core and the spiral spring rod are excessively bent, the dense state of the two ends of the spiral spring rod can compress the air storage sleeve, the rotation belt is gradually stretched through airflow to drive the spiral spring rod to rotate, when the bending acting force disappears, the rotation belt automatically shrinks to drive the spiral spring rod to rotate, the bending direction of the spiral spring rod is changed, and therefore bending of the cable core is further corrected.

Description

technical field [0001] The invention relates to the field of cables, more specifically, to a spiral correction type 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.

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 bending force. However, once the external force is large and the action time is long, As a result, the cable is subject to long-term and large bending, and the cable itself has limited bending resistance, which will cause the cable to bend excessively and it is difficult to restore the original shape, so that the internal conductive core is cracked and damaged due to bending, making the cable unable to be used in normal production
