While enhancing the tensile strength and softness of the conductor, it can also increase the conductor cross-section and have a conductive function, providing the conductor's carrying capacity. The insulation reinforcement layer adopts aramid weaving as a reinforcement layer, which can enhance the tensile strength of the entire cable. The high-elastic fixed layer adopts an extrusion fixed slot mode to keep the cable cores in a self-locking fixed state, ensuring that when the insulation core is relatively displaced after bending or moving, the memory function of the high-elastic fixed slot is used to quickly restore the insulation core to its original position, thereby ensuring the relative stability of the cable insulation structure. The tensile reinforcement layer is reinforced by aramid secondary weaving, with the weaving angle controlled at 30°-40° and the weaving density controlled at 50%-60%, which further enhances the tensile strength of the cable. The insulation layer 300 has a good sealing effect, which can isolate the internal and external environments and prevent damage to the device.

While enhancing the tensile strength and softness of the conductor, it is also possible to increase the conductor cross-section and conduct electricity, thereby providing the conductor with a carrying capacity.

[0021] In an optional embodiment: the insulating layer 300 is made of acrylic acid, and the thickness of the acrylic acid is 0.2 mm. The insulating layer 300 has a good sealing effect, can isolate the internal and external environments, and prevent the device from being damaged.

[0026] Working principle of this utility model:

[0027] The conductor reinforcement layer adopts copper wire + aramid braiding as the reinforcement layer. The copper wire and aramid are in the same direction, so that when the conductor is stressed, the copper wire and aramid are stressed evenly and the tension changes consistently. While enhancing the tensile resistance and softness of the conductor, it can also increase the conductor cross-section and have the conductive function, providing the conductor's carrying capacity. The insulation reinforcement layer adopts aramid braiding as the reinforcement layer, which can enhance the tensile resistance of the entire cable. The high elastic fixed layer adopts the extrusion fixed card slot mode to keep the cable cores in a self-locking fixed state, ensuring that when the cable is bent or moved, the insulation core has a relative displacement. The memory function of the high elastic fixed card slot is used to quickly restore the insulation core to its original position, ensuring the relative stability of the cable insulation structure. The tensile reinforcement layer adopts aramid secondary braiding to strengthen, the braiding angle is controlled at 30°-40°, and the braiding density is controlled at 50%-60%, which plays a role in enhancing the tensile resistance of the cable again. The insulation layer 300 has a good sealing effect, which can isolate the internal and external environment and prevent the device from being damaged. The outer sheath 700 has good wear resistance and can protect the cable from damage externally.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
