Description

Cable with improved cable tension Technical Field The invention relates to the technical field of elastic cables, in particular to a cable. Background The elastic cable has a wider application range, for example, when the mechanical operating arm, the robot operating arm and the like are used, the cable is severely damaged due to high-frequency vibration stretching when in use, and is mainly concentrated at the position of the end part, and when in use, the end part positioned above the cable is subjected to twisting force generated when the cable is stretched, so that the deformation of the position is serious, the damage condition is heavy, and the equipment is inconvenient to use due to breakage. Disclosure of Invention The invention aims to provide a cable which has the advantages of better adaptability and capability of resolving deformation generated by twisting, ensuring that the layers are not damaged, and reducing damage to deformation positions. In order to achieve the above purpose, the invention provides a cable comprising: The cable comprises a cable main core, a cable guide plate and a cable guide plate, wherein the cable main core comprises a main cable core and a plurality of sub cable cores, and the plurality of sub cable cores are arranged around the main cable core; The wrapping layer is sleeved on the cable main core, reinforcing rib parts are arranged at two ends of the wrapping layer, the outer ends of the reinforcing rib parts are fixedly connected with ends, and the cable main core penetrates through the ends; The cable main core adopts the central main cable core to match the multi-strand split cable core to encircle the setting, and such benefit lies in that when traditional single cable is tensile, stress can concentrate on single conductor and insulating layer, leads to inside copper wire fracture, insulating layer fracture easily. The main cable core plays a role of supporting a skeleton, can maintain a spiral basic form, prevents the cable from being excessively deformed, twisted or scattered during stretching, and the surrounding cable core can synchronously stretch along with the spiral structure to match with the support of the central cable, so that the elastic stretch of the cable is more controllable, the cable can rebound to an original state quickly after stretching, the loosening problem that the cable cannot reset after stretching does not occur, and the layered structure can be used for classifying and arranging cables with different functions, such as arranging a power line in the center and surrounding a signal line and a control line. In the stretching process, cables with different functions cannot be mutually extruded and wound, the stability of signal transmission can be guaranteed, the number of the sub-cables can be conveniently increased according to requirements, the functions of the cables are expanded, the conductor resistance of the cables can slightly fluctuate due to length change during stretching, the parallel/independent arrangement of the multi-strand sub-cables can disperse current, and heating caused by overlarge current of a single cable is avoided. Meanwhile, the gaps formed by the surrounding structure can improve heat dissipation efficiency and reduce the influence of heat accumulation on insulating materials and transmission performance. The end is provided, the main cable core and the branch cable core are limited by the sleeve cap, the sleeve cap positions the internal branch cable, the tension can be accurately and uniformly distributed on each main cable and each branch cable, and the single cable is prevented from being broken due to uneven stress caused by 'independent dragging'; the outer layer fixing sleeve is used for fastening the whole cable and receiving the external whole stretching force, and simultaneously transmitting the external force to the fixing seat to form an external-pulling-internal-dividing stressed chain, so that the risk of stress concentration at the end part is greatly reduced; the sleeve cap limits the relative positions of the main cable and the sub cable from the inside, prevents the sub cable from separating from the central surrounding track when being stretched, the fixing sleeve is used for hooping the outer wrapping layer of the whole cable from the outside, so that cracking and wrinkling of the outer wrapping layer due to stretching are avoided, and meanwhile, the integral end part shape of all cables is further locked, and even in high-frequency stretching-rebound circulation, the central-surrounding design structure can be maintained, and dislocation and winding of the cables are avoided; The junction of the outer covering of the cable end with the inner cable is the weakest point of tensile fatigue. The fixing sleeve can strengthen the tearing resistance of the outer wrapping layer and prevent the outer wrapping layer from being stripped from the inner cables due to repeated stretching, and the cap c
