Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and more specifically, to a cable with a highly resilient sheath structure. Background Technology

[0002] In industrial production, infrastructure construction, and new energy fields, cables, as core components for energy and signal transmission, often face complex and harsh operating environments. For example, in engineering machinery wiring scenarios, cables need to bend and twist frequently with the robotic arm; in mining environments, cables may be subjected to rockfall impacts and continuous vibrations; and in cable shafts of high-rise buildings, long-term load-bearing will cause cables to be subjected to axial tensile stress.

[0003] Traditional cable sheaths are mostly made of single rubber or plastic materials, which can only meet basic insulation and protection requirements. When subjected to axial tension, the battery core is prone to breakage due to excessive stress; during repeated bending, the outer side of the sheath is prone to cracks due to tensile fatigue; when faced with external impact, the impact energy is directly transferred to the battery core, which may lead to internal structural damage. In addition, although some cables have added reinforcing layers, due to the lack of a coordinated stress dispersion mechanism in the structural design, they are still unable to cope with various situations under complex working conditions. When the cable is damaged, it may lead to safety accidents.

[0004] Therefore, there is an urgent need for a cable with a highly resilient sheath structure to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a cable with a highly resilient sheath structure. This cable employs an elastic spiral tension cable located outside the core, which protects the core through a spiral winding method. Multiple waveguide-type buffer units are arranged outside the core on the outside of the elastic spiral tension cable. Through the compression and expansion of the waveform, the concentrated impact energy is converted into elastic potential energy and then gradually released, thereby solving the problems mentioned in the background art.

[0006] Traditional cable sheaths are mostly made of a single rubber or plastic material, which can only meet basic insulation and protection requirements. When subjected to axial tension, the battery core is prone to breakage due to excessive stress.

[0007] To achieve the above objectives, this utility model provides a cable with a highly resilient sheath structure, including a cable wire with a battery core at its center;

[0008] An elastic helical tension cable is wrapped around the outer surface of the battery cell in a helical winding manner to resist axial tensile stress and bending tensile lateral stress.

[0009] The outer side of the elastic spiral tension cable is covered with a first rubber diaphragm.

[0010] The second rubber separator is coaxially sleeved outside the first rubber separator;

[0011] An annular cavity is formed between the first rubber separator and the second rubber separator;

[0012] Multiple waveguide-type buffer units are arranged in parallel along the cable axis and fixed in the annular cavity to disperse stress and buffer impact energy through waveform deformation.

[0013] In the above technical solution, the elastic spiral tension cable wound around the outer edge of the battery cell resists axial tensile stress and bending tensile lateral stress. The first rubber partition on the outer side plays an insulating and fixing role, and the second rubber partition coaxially sleeved forms an outer layer of protection. In the annular cavity between the two partitions, multiple waveguide buffer units arranged parallel along the axial direction disperse stress and buffer impact energy through waveform deformation. All structures work together to achieve a highly tough sheath protection function.

[0014] Based on this, the outer layer of the battery cell is made of thermoplastic polyurethane with a flat cross-section and overlapping adjacent spiral coils. The spiral winding can effectively resist axial tensile stress and bending tensile lateral stress. The first rubber separator on the outside serves as insulation and fixation, and the second rubber separator coaxially sleeved forms an outer layer of protection. In the annular cavity between the two separators, multiple waveguide buffer units arranged parallel to each other along the axial direction disperse stress and buffer impact energy through waveform deformation. All structures work together to achieve a highly tough sheath protection function.

[0015] In another technical solution, the waveguide buffer unit is made of silicone rubber, and adjacent waveguide buffer units are distributed in parallel.

[0016] This technical solution uses an elastic spiral tension cable wound around the outer edge of the battery cell to resist axial tensile stress and bending tensile lateral stress. The first rubber separator on the outer side serves as insulation and fixation, while the second rubber separator, coaxially sleeved, forms an outer protective layer. In the annular cavity between the two separators, adjacent waveguide buffer units arranged in parallel along the axial direction and made of silicone rubber are distributed in parallel. Through waveform deformation, stress is dispersed and impact energy is buffered. All structures work together to achieve a highly tough protective sheath function.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This cable, with its highly resilient sheath structure, features an elastic helical tension cable on the outer layer of the battery core, forming the first line of mechanical protection through a helical winding. Its flat cross-section and the partial overlap of adjacent helical coils allow the tension to be evenly distributed across the entire tension cable through the elastic deformation of the helical structure when the cable is subjected to axial tension, preventing the battery core from directly bearing excessive tensile force. When the cable bends, the tension cable on the bending and tensile side generates reverse elastic stress due to the change in the helical angle, offsetting part of the tensile load and reducing the deformation of the sheath and battery core, thereby resisting the stress on the bending and tensile side.

[0019] Multiple waveguide-type buffer units arranged parallel to each other along the axial direction within the annular cavity form the core structure for coping with impacts and complex stresses. The high elasticity of silicone rubber allows it to deform into a waveform when subjected to radial or axial impacts. Through the compression and expansion of the waveform, the concentrated impact energy is converted into elastic potential energy, which is then gradually released. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Currently, traditional cable sheaths mostly use a single rubber or plastic material, which only meets basic insulation and protection requirements. When subjected to axial tension, the 110 core is prone to breakage due to excessive stress. Please refer to [link / reference needed]. Figures 1-3 As shown, this embodiment provides a cable with a highly resilient sheath structure, including a cable 100, with a battery core 110 at its center;

[0027] The elastic spiral tension cable 120 is wrapped around the outer surface of the battery cell 110 in a spiral winding manner to resist axial tensile stress and bending tensile lateral stress.

[0028] The elastic spiral tension cable 120 is covered with a first rubber diaphragm 130 on its outer side;

[0029] The second rubber partition 150 is coaxially sleeved outside the first rubber partition 130;

[0030] An annular cavity is formed between the first rubber separator 130 and the second rubber separator 150;

[0031] Multiple waveguide-type buffer units 140 are arranged in parallel along the cable axis and fixed in the annular cavity to disperse stress and buffer impact energy through waveform deformation.

[0032] In practice, the cable 100 directly resists axial tensile stress and bending tensile lateral stress through the elastic spiral tension cable 120 spirally wound around the battery core 110. The first rubber diaphragm 130 on the outside serves as insulation and fixation, and the coaxially sleeved second rubber diaphragm 150 forms an outer layer of protection. In the annular cavity between the two diaphragms, multiple waveguide buffer units 140 arranged parallel along the axial direction further disperse stress and buffer impact energy through waveform deformation. All structures work together to achieve comprehensive protection of the battery core 110 and improve the high toughness of the cable sheath.

[0033] See Figure 2 As shown, the elastic spiral tension cable 120 wound around the outer side of the battery cell 110 can resist axial tensile stress and bending tensile lateral stress. The first rubber separator 130 on its outer side plays the role of insulation and fixation. The second rubber separator 150 coaxially sleeved forms an outer layer of protection. In the annular cavity between the first rubber separator 130 and the second rubber separator 150, multiple waveguide buffer units 140 are arranged in parallel along the axial direction. These buffer units can disperse stress and buffer impact energy through waveform deformation. The various structures cooperate with each other to achieve a highly tough sheath protection function.

[0034] Figure 3 In the middle, outside the battery core 110, there is an elastic spiral tension cable 120 made of thermoplastic polyurethane with a flat cross-section and overlapping adjacent spiral coils. It can effectively resist axial tensile stress and bending tensile lateral stress through spiral winding. The first rubber partition 130 outside the elastic spiral tension cable 120 plays the role of insulation and fixation. A second rubber partition 150 is coaxially sleeved outside the first rubber partition 130. An annular cavity is formed between the two partitions. Multiple waveguide buffer units 140 are arranged and fixed in parallel along the cable axis in the cavity. They can disperse stress and buffer impact energy through waveform deformation. The various structures work together to achieve high toughness of the cable sheath.

[0035] In this embodiment, a cable with a highly resilient sheath structure is used in the following way: First, the core 110 of the cable 100 is covered with an elastic spiral tension cable 120 made of thermoplastic polyurethane, with a flat cross-section and overlapping adjacent spiral coils. The cable effectively resists axial tensile stress and bending tensile lateral stress through spiral winding. The first rubber diaphragm 130 on the outside of the elastic spiral tension cable 120 serves to insulate and fix the cable, providing stable support for the internal structure.

[0036] A second rubber partition 150 is coaxially sleeved on the outside of the first rubber partition 130, forming an annular cavity between the two partitions. Multiple waveguide buffer units 140 made of silicone rubber are arranged and fixed in parallel along the cable axis inside the cavity. These units can further disperse stress and buffer impact energy through waveform deformation, and work together with the aforementioned structure to achieve high toughness of the cable sheath.
