Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a flexible cable with good heat dissipation. Background Technology

[0002] Cables are an indispensable transmission medium in modern electronic equipment, widely used in various electrical appliances and communication systems. Existing cables include various types such as fire-resistant cables, deep-sea cables, and flexible cables. Among them, flexible cables, due to their bend resistance and lightweight characteristics, are widely used in devices requiring frequent bending and movement, such as robotic arms and robots, to achieve efficient power and data transmission.

[0003] However, existing flexible cables suffer from poor heat dissipation, which can easily lead to overheating of the cable core after prolonged use. This affects the cable's power and data transmission, causing a decline in equipment performance or even damage, and ultimately affecting the normal operation of the equipment. Therefore, this invention proposes a flexible cable with better heat dissipation. Summary of the Invention

[0004] This invention provides a flexible cable with good heat dissipation, which solves the problem of poor heat dissipation in existing flexible cables by optimizing the cable structure.

[0005] The objective of this utility model is achieved through the following means:

[0006] A flexible cable with good heat dissipation includes a cable core and an inner sheath, a wrapping layer, and an outer sheath that are sequentially wrapped around the outside of the cable core from the inside to the outside. A heat-conducting layer is provided between the inner sheath and the cable core. A plurality of support sleeves that cooperate with the cable core are provided in the heat-conducting layer. The plurality of support sleeves are arranged in an array along the length direction of the cable core. Heat-conducting filler is filled between the support sleeves.

[0007] Furthermore, the outer side of the support sleeve is provided with several anti-slip grooves, and the heat-conducting layer is provided with anti-slip blocks that cooperate with the several anti-slip grooves.

[0008] Furthermore, the cable core includes a flexible support core and a plurality of conductors surrounding the outside of the flexible support core, and the support sleeve is provided with a slot that cooperates with the flexible support core and the plurality of conductors.

[0009] Furthermore, the flexible support core has a memory metal wire at its axis.

[0010] Furthermore, the spacing between the support sleeves is 10 cm.

[0011] Furthermore, a woven armor layer is provided between the wrapping layer and the outer sheath.

[0012] Furthermore, the outer sheath has several wear-resistant ribs protruding from its outer side.

[0013] Furthermore, each of the wear-resistant ribs is circular, and the wear-resistant ribs are arranged in an array along the length of the cable core.

[0014] The beneficial effects of this invention are as follows: The support sleeve and thermally conductive filler within the thermally conductive layer create several support and flexible sections in the cable, thereby improving its flexibility and bending performance.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figure 1 - Figure 5 The specific implementation of the flexible cable with good heat dissipation includes a cable core 1 and an inner sheath 2, a wrapping layer 3 and an outer sheath 4 wrapped around the outside of the cable core 1 from the inside to the outside. A heat-conducting layer 5 is provided between the inner sheath 2 and the cable core 1. A number of support sleeves 51 that cooperate with the cable core 1 are provided in the heat-conducting layer 5. The number of support sleeves 51 are arranged in an array along the length direction of the cable core 1. Heat-conducting filler 52 is filled between the support sleeves 51.

[0023] The cable, through the combination of arrayed support sleeves 51 and thermally conductive filler 52, forms a structure with alternating support and flexible sections. The support sections provide stable support, while the flexible sections ensure the cable can bend flexibly. During manufacturing, by adjusting the spacing of the support sleeves 51 and the amount of thermally conductive filler 52, the bending radius and heat dissipation performance of the cable can be precisely controlled, ensuring that the cable possesses both good flexibility and efficient heat dissipation in different application scenarios, thus extending its service life.

[0024] In this embodiment, the spacing between the support sleeves 51 is 10 cm. The 10 cm spacing design ensures the uniform distribution of support points when the cable is bent, while also ensuring the flexibility of the cable, avoiding excessive rigidity due to overly dense support points, or insufficient support due to overly sparse support points.

[0025] Both the inner sheath 2 and the outer sheath 4 are made of polyurethane. Polyurethane is characterized by its abrasion resistance, high flexibility, and oil resistance, allowing the cable to withstand frequent bending without easily being damaged. This makes the cable suitable for dynamic equipment such as robotic arms. The wrapping layer 3 is made of mica tape. Mica tape has excellent high-temperature resistance, flame retardancy, and electrical insulation properties, enabling the cable to maintain stable performance in high-temperature environments, effectively preventing short circuits and fire risks, and improving overall safety and reliability. Furthermore, its thermal stability helps the heat-conducting layer 5 disperse heat, thereby reducing the conductor temperature and extending the cable's service life.

[0026] The heat-conducting layer 5 can be made of thermally conductive materials such as silicone rubber or fluoroplastics, using a wrapping tape or heat-conducting sleeve to enclose the cable core 1, support sleeve 51, and heat-conducting filler 52, forming an efficient heat conduction path. This ensures rapid heat dissipation, reduces the temperature of the cable core 1, prevents overheating of the cable leading to performance degradation or damage, and ensures stable equipment operation. In this embodiment, a heat-conducting sleeve made of silicone rubber is used. Its high thermal conductivity and good flexibility allow it to enclose the cable core 1, support sleeve 51, and heat-conducting filler 52 while adaptively adjusting to the bending deformation of the cable, ensuring the continuity and effectiveness of the heat conduction path. This avoids problems such as poor heat dissipation due to bending, further improving the cable's adaptability and durability in complex environments.

[0027] The outer side of the support sleeve 51 is provided with several anti-slip grooves 511, and the heat-conducting layer 5 is provided with anti-slip blocks 53 that cooperate with the several anti-slip grooves 511. The cable core 1 includes a flexible support core 11 and several conductors 12 arranged around the outer side of the flexible support core 11. The support sleeve 51 is provided with a slot 512 that cooperates with the flexible support core 11 and the several conductors 12. The axis of the flexible support core 11 is provided with a shape memory metal wire 13.

[0028] In this embodiment, the anti-slip block 53 is integrally formed with the silicone rubber thermal conductive sleeve. Through the elasticity and adhesion of the silicone rubber, the anti-slip block 53 fits tightly with the anti-slip groove 511, firmly fixing the support sleeve 51 inside the cable. This prevents the support sleeve 51 from rotating or shifting during dynamic use, ensuring the cable maintains structural stability even during complex movements. Furthermore, the slot 512 securely fixes the flexible support core 11 and the conductor 12, preventing displacement during bending and ensuring the stability of the cable's internal structure. The shape memory metal wire 13 provides the flexible support core 11 with excellent recovery properties, allowing the cable to return to its original shape after multiple bends, reducing fatigue damage during long-term use.

[0029] The conductor 12 consists of a conductor and an insulating sleeve. The insulating sleeve is located on the outer diameter of the conductor. The conductor is made of multiple silver-plated copper alloy wires spirally twisted together. The silver-plated copper alloy wires have good conductivity and corrosion resistance, thereby improving the conductivity and durability of the cable and ensuring the stability and efficiency of signal or power transmission. At the same time, the insulating sleeve is made of a special material that is resistant to high temperatures and wear, further enhancing the cable's protective performance and ensuring that it maintains excellent insulation performance even in extreme environments, effectively preventing leakage and short circuits, and improving overall safety and reliability.

[0030] A braided armor layer 6 is provided between the wrapping layer 3 and the outer sheath 4. The braided armor layer 6 can be woven from high-strength materials such as steel wire, copper wire, or aramid. The braided design gives the armor layer good tensile strength and flexibility, allowing it to deform with the bending of the flexible cable without easily breaking. Thus, without affecting the cable's flexibility, it provides additional mechanical protection for the cable, preventing damage from external forces. This further enhances the overall protection capability of the cable.

[0031] The outer sheath 4 has several protruding abrasion-resistant ribs 41. These ribs 41 are integrally formed with the outer sheath 4, increasing its abrasion resistance and effectively resisting external friction and wear, thus extending the cable's service life. The abrasion-resistant ribs 41 can be arranged in a spiral or ring shape along the length of the cable core 1. Without affecting the cable's flexibility, they provide all-around protection, ensuring the cable maintains excellent abrasion resistance even in harsh environments, further enhancing overall durability.

[0032] In this embodiment, several wear-resistant ribs 41 are all annular, and these ribs 41 are arranged in an array along the length of the cable core 1. The annular design effectively disperses frictional force, reduces the area of ​​the sheath directly contacting the wear surface, and provides uniform radial support force to prevent the cable from deforming under pressure or torsion. It also serves as an anti-slip agent, increasing grip stability, preventing slippage when pulling out the cable, and improving ease of operation.

[0033] The beneficial effects of this invention are as follows: The support sleeve 51 and thermally conductive filler 52 within the thermally conductive layer 5 create several support and flexible sections in the cable, thereby improving the cable's flexibility and bending performance. Furthermore, the cooperation between the thermally conductive layer 5 and the thermally conductive filler 52 rapidly conducts the heat generated by the cable core 1 to the outside, effectively reducing the temperature of the cable core 1, extending the cable's service life, and ensuring stable equipment operation.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
