[0023] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0024] See attached document Figure 1 As shown, an ultra-flexible industrial robot drag chain cable includes a cable sheath 1 made of wear-resistant material, multiple sets of cables 2 arranged inside the cable sheath 1, and tensile reinforcement components. The cable sheath 1 is extruded by a semi-extrusion method, which meets the requirements of flexibility, wear resistance, and oil resistance, and the material can be specially customized according to special working conditions.

[0025] In one embodiment of this utility model, the cable 2 includes a cable insulation layer 21 and multiple strands of wires disposed within the cable insulation layer 21. The wires include conductors 22 of several stranded copper material components, which can meet the product flexibility requirements.

[0026] In one embodiment of this utility model, the diameter of the conductor 22 is set to be less than 0.1 mm, and the tensile strength and elongation at break of the conductor 22 are designed and controlled to mainly balance the flexibility and rigidity of the conductor 22. At the same time, the de-twist rate when the conductor 22 is stranded is specially formulated, so that each wire is arranged in a more reasonable posture inside the cable 2 to meet the bending requirements and the corresponding production load capacity.

[0027] In one embodiment of the present invention, the tensile reinforcement component includes conductor reinforcement 31 disposed in each cable 2, inner gap reinforcement 32 disposed between adjacent cables 2, and outer gap reinforcement 33, wherein the conductor reinforcement 31 fills the space between adjacent conductors.

[0028] In one embodiment of this utility model, the conductor reinforcement 31 is an aramid composite material component, and the specifications are selected according to the conductor structure and size. The conductor reinforcement 31 is an aramid composite material component, which also meets the characteristics of being soft, tensile, conductive, and having a small outer diameter.

[0029] After the position arrangement design is carried out according to the single wire arrangement position and strand distribution position of conductor 22 during the process of conductor 22 bundle and twisting, the position is arranged by a customized wire separator and reasonably distributed with conductor 22, so as to complete the deformation restraint and stress complementarity with conductor 22 during bending and torsion.

[0030] In one embodiment of this utility model, by providing conductor reinforcement members 31 with conductive material components in each cable 2, and providing inner gap reinforcement members 32 and outer gap reinforcement members 33 between adjacent cables 2 to achieve complementarity, the effects of cable bending on the tension and compression of the cable 2 and its internal insulation structure can be minimized. Thus, the cable can meet the requirements of torsion and tensile strength while taking into account flexibility.

[0031] In one embodiment of this utility model, the outer gap reinforcement 33 is a tensile element that is uniformly distributed around the periphery of the adjacent cable 2 before the sheath is extruded. The outer gap reinforcement 33 specifically includes a first outer layer of elastic material component and a first central layer of aramid composite material component. The outer gap reinforcement 33 is arranged in a spiral pattern with the twist pitch of the cable 2, thereby complementing the inner gap reinforcement 32.

[0032] In one embodiment of this utility model, the inner gap reinforcement 32 is a cable filling reinforcement during the stranding of the cable 2, which can minimize the stretching and compression effects of cable bending on the cable 2 and the internal insulation structure. The inner gap reinforcement 32 includes a second outer layer of elastic material component and a second central layer of aramid composite material component, which can resist stretching and bending operations.

[0033] In one embodiment of this utility model, the shape and size of the inner gap reinforcement 32 can be individually designed and matched according to the specific number of cores and arrangement, thereby ensuring that the stranding is round while the inner gap reinforcement 32 bears part of the longitudinal load. Furthermore, a special design is adopted for the stranding pitch during the cable formation process, and the insulated cores are appropriately untwisted to ensure the reasonable posture of the insulated cores during cable formation.

[0034] This drag chain cable features a tensile-strengthened component structure design, and the corresponding materials are selected based on the characteristics of the cable sheath 1 and the cable 2, so that the finished cable can meet the requirements of flexibility, wear resistance, oil resistance, tensile strength, and torsion resistance, and meet the requirements of tens of millions of bending tests without core breakage.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
