Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a highly flexible soft cable. Background Technology

[0002] A cable is a conductor consisting of one or more mutually insulated conductors and an outer insulating protective layer, laid underground, in the air, etc. Cables generally consist of three parts: a conductor, an insulation layer, and a protective layer. There are usually two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy; control cables are mainly used for measurement, protection, and control circuits.

[0003] In the field of industrial automation, a large number of automated equipment and robots are widely used. They require frequent and flexible movement. Due to their insufficient flexibility, traditional cables are prone to internal structural damage during repeated bending and twisting, leading to problems such as core breakage and insulation layer rupture, which in turn cause electrical faults, affecting production efficiency and increasing equipment maintenance costs. In some situations with stringent space requirements, such as the internal wiring of small electronic devices or precision instruments, the rigidity of traditional cables makes it difficult to achieve compact and reasonable wiring, limiting the miniaturization and integration of equipment. Therefore, this application proposes a highly flexible soft cable. Utility Model Content

[0004] The purpose of this invention is to address the problem of low flexibility in traditional cables in the background art by proposing a highly flexible soft cable.

[0005] The technical solution of this utility model is as follows: A highly flexible soft cable, including a wear-resistant layer, and further comprising:

[0006] A connecting layer is fitted inside the wear-resistant layer. Multiple protective layers arranged in a circular pattern at equal intervals are fixedly installed inside the connecting layer. Multiple wire cores are fixedly installed inside the protective layers. An auxiliary mechanism to improve the flexibility of the cable is provided inside the wear-resistant layer.

[0007] Optionally, the auxiliary mechanism includes a rubber pad fixedly installed in the wear-resistant layer, the side of the rubber pad being in contact with the side of the protective layer, the protective layer being filled with a first filling layer being in contact with the side of the wire core, the rubber pad having a plurality of equidistant circumferentially arranged mounting holes, the mounting holes having sealing holes, and the wear-resistant layer having a connection mechanism to improve the tensile strength of the cable.

[0008] Optionally, the connecting mechanism includes a connecting layer fixedly installed within the wear-resistant layer, a hemp rope braiding layer fixedly installed on the inner side of the connecting layer, an insulating layer fixedly installed on the inner side of the hemp rope braiding layer, a second filling layer provided on the inner side of the insulating layer, the second filling layer contacting the outer side of the protective layer and the rubber pad, and a bearing core fixedly installed inside the rubber pad.

[0009] Optionally, the thickness of the wear-resistant layer and the connecting layer is 0.2-0.3 cm, and an adhesive is filled between the wear-resistant layer and the connecting layer.

[0010] Optionally, the hemp rope braided layer adopts a cross-weaving process, and the thickness of the hemp rope braided layer is 0.3-0.4 cm.

[0011] Optionally, the radius of the bearing core is 1-2 cm, and the bearing core adopts a galvanized steel wire structure.

[0012] Optionally, a flame retardant is provided on the outer side of the wear-resistant layer, and a protective film is provided on the surface of the flame retardant.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention, through the auxiliary mechanism, allows the cable core to be squeezed against the rubber pad when it bends, providing deformation buffer stress. The first filling layer reduces friction between the core and the protective layer, allowing it to move freely when bending, thus improving the cable's flexibility.

[0015] Furthermore, the galvanized steel wire installed within the connecting mechanism enhances the strength of the cable core. Combined with the hemp rope braiding layer, this further improves the cable's tensile strength, extends its service life, and enhances its practicality. Attached Figure Description

[0025] Example

[0026] like Figure 1-2As shown, this utility model proposes a highly flexible soft cable, including a wear-resistant layer 1 made of polyurethane, which has high strength, high toughness, and excellent wear resistance, maintaining good integrity under frequent friction and bending. It also has excellent oil resistance, water resistance, chemical corrosion resistance, and low-temperature resistance, maintaining stable performance under different environmental conditions. It also includes a connecting layer 11, which is sleeved inside the wear-resistant layer 1. Multiple protective layers 5 arranged circumferentially at equal intervals are fixedly installed inside the connecting layer 11. The protective layers 5 are made of polyvinyl chloride, which has low cost, certain flexibility, mechanical strength, and corrosion resistance, and good insulation performance, providing basic protection for the cable. Multiple wire cores 7 are fixedly installed inside the protective layers 5. An auxiliary mechanism to improve the flexibility of the cable is provided inside the wear-resistant layer 1.

[0027] like Figure 2 As shown, the auxiliary mechanism includes a rubber pad 8 fixedly installed inside the wear-resistant layer 1. The side of the rubber pad 8 is in contact with the side of the protective layer 5, so that when the cable is bent, the conductor 7 is squeezed against the protective layer 5. The protective layer 5 and the rubber pad 8 are in contact, which provides cushioning during bending, allowing the conductor 7 to move more freely and improving the flexibility of the cable when bending. The protective layer 5 is filled with a first filler layer 6, which is made of silicone rubber. The first filler layer 6 is soft and elastic, and can adapt to various complex bending and torsion conditions. It has excellent high temperature and low temperature resistance, and can maintain good flexibility in extremely cold and high temperature environments. It also has excellent electrical insulation, which can ensure the stability of the electrical performance of the cable. The first filler layer 6 is in contact with the side of the conductor 7. The rubber pad 8 has multiple equidistant circumferentially arranged mounting holes 12, and sealing holes 9 are opened in the mounting holes 12. The wear-resistant layer 1 is provided with a connecting mechanism to improve the tensile strength of the cable.

[0028] like Figure 1 As shown, the connection mechanism includes a connecting layer 11 fixedly installed within the wear-resistant layer 1. A hemp rope braided layer 2 is fixedly installed inside the connecting layer 11, and an insulation layer 3 is fixedly installed inside the hemp rope braided layer 2. The insulation layer is made of polyethylene, which has excellent electrical insulation properties, a low dielectric constant, and high insulation resistance, effectively reducing signal transmission loss. It also exhibits strong chemical stability, resisting the erosion of most chemicals, and good water resistance, making it suitable for humid environments. A second filling layer 4 is provided inside the insulation layer 3. The second filling layer 4 is made of aramid fiber, possessing high flexibility and tensile strength, and can act as a reinforcement and buffer in the filling layer. These fiber materials also improve the cable's tear resistance, making the cable less prone to damage when subjected to external pulling forces, while also helping to maintain the cable's overall shape and flexibility. The second filling layer 4 contacts the outer side of the protective layer 5 and the rubber pad 8. A bearing core 10 is fixedly installed inside the rubber pad 8.

[0029] The wear-resistant layer 1 and the connecting layer 11 have a thickness of 0.2-0.3 cm. An adhesive is filled between them to improve connection stability. The hemp rope braided layer 2 uses a cross-braiding process and has a thickness of 0.3-0.4 cm. The bearing core 10 has a radius of 1-2 cm and is made of galvanized steel wire. A flame retardant is applied to the outside of the wear-resistant layer 1, and a protective film is applied to its surface to prevent the cable from igniting when exposed to a fire source, thus providing flame retardancy and improving cable safety. The protective film on the surface of the flame retardant protects it from external damage, extending its service life and ensuring the stability of its flame-retardant performance.

[0030] The working principle of this embodiment is as follows: By setting a wear-resistant layer 1 on the outside of the core 7, the overall wear resistance of the cable is improved. A flame retardant is set on the outside of the wear-resistant layer 1, and a protective film is set on the surface of the flame retardant to prevent the cable from being ignited when it encounters a fire source, thus playing a flame-retardant role and improving the safety of the cable. The protective film on the surface of the flame retardant can protect the flame retardant from being damaged by external factors, extend the service life of the flame retardant, and ensure the stability of its flame-retardant performance. The rubber pad 8 plays an important role. It is fitted outside the protective layer 5 and has good flexibility and elasticity. When the cable is bent or subjected to external force, the rubber pad 8 can deform to buffer stress and prevent the protective layer 5 and the core 7 from being damaged by excessive impact force, thereby improving the flexibility of the cable. The carrying core 10 adopts a galvanized steel wire structure, and the galvanized steel wire has high strength and tensile strength. Located within the rubber pad 8, it can withstand the tensile force on the cable. When the cable is stretched, the bearing core 10 can effectively disperse the tensile force, preventing the cable from breaking due to insufficient tensile strength. The hemp rope braided layer 2 adopts a cross-braiding process. The cross-braided structure gives it a certain tensile strength, and the hemp rope itself has a certain toughness. When the cable is stretched, the hemp rope braided layer 2 can assist the bearing core 10 in bearing the tensile force, further enhancing the tensile performance of the cable. This utility model improves the overall tensile strength and flexibility of the cable, enhances the practicality of the cable, and extends its service life.

[0031] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
