[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

Abstract
The invention discloses a helical rectification type anti-bending cable, which belongs to the field of cables. In the invention, a helical rectification sleeve is arranged between the cable core and the outer sheath. The inflection point moves to both sides, showing the bending state of dense at both ends and evacuated in the middle. On the basis of the bending resistance of the cable core and the outer sheath itself, the anti-deformation force of the coil spring bar provides further bending resistance for the cable core. , so that the cable core can be quickly restored to a straight state through the elasticity of the coil spring rod after bending, and when the cable core and the coil spring rod are both bent excessively, the dense state at both ends of the coil spring rod will cause compression of the gas storage sleeve. The air flow makes the slewing belt gradually stretch, which drives the coil spring rod to rotate. When the bending force disappears, the slewing belt automatically shrinks and drives the coil spring rod to rotate, changing the bending direction of the coil spring rod, so as to further correct the bending of the cable core.
Description
technical field [0001] The present invention relates to the field of cables, and more particularly, to a helical 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 and so on. They are all composed of single or multi-strand wires and insulating layers, which are used to connect circuits, 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 flexural resistance refers to the bending resistance of a material. [0004] In the process of transpo...
