Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a bending-resistant cable. Background Art

[0002] It is a wire made of one or more mutually insulated conductors and an outer insulating protective layer. These conductors are usually twisted into a rope-like shape. Each group of wires are insulated from each other and are often twisted around a center. The entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation, and can be made into various specifications and types according to different application scenarios, such as household cables, power cables, communication cables, etc. Usually, some cables will pass through some corners when they are laid, so they need to be bent. Most of the traditional bending methods of some cables are to bend directly and bend autonomously. This kind of bending form will make the bending position of the cable unevenly stressed, which is prone to bending and breaking, resulting in a lack of safety in the use of the cable. Therefore, in order to avoid such problems, the present application proposes a bending-resistant cable with auxiliary guided bending to solve such problems. Utility Model Content

[0026] Reference Figure 1-3, an embodiment provided by the utility model: a bending-resistant cable, comprising a cable body 1, a bending and shaping frame 2 is nested on the outer side of the cable body 1, the setting of the bending and shaping frame 2 can play a stable shaping effect on the bending position of the cable, can assist the cable in bending, and can also avoid the situation where the cable is easily broken at the bending position when it is bent independently, ensuring that the bending position presents an arc-shaped transition, the force is evenly balanced, and it is not easy to bend and break. The bending and shaping frame 2 is composed of a first shaping frame 21 and a second shaping frame 22. The inner surfaces of the first shaping frame 21 and the second shaping frame 22 are both provided with positioning slots 3, and the two positioning slots 3 are butted They are combined together to form a through groove structure with a circular cross-section. The cable body 1 and the through groove are nested and matched. The positioning slots 3 on the two shaping frame structures cooperate with each other, and the cable can be stably coated, fitted and fixed so that it can be stably positioned. The first shaping frame 21 and the second shaping frame 22 are respectively provided with a protective cushion layer 4, a shaping frame base layer 5 and an outer protective layer 7 from the inside to the outside. A strengthening layer 6 is provided in the base layers 5 of the two shaping frames. A docking block 8 is fixedly connected to the second shaping frame 22, and a fixing protrusion 9 is fixedly connected to the docking block 8. A docking slot 10 is provided on the first shaping frame 21, and a fixing groove 11 is provided on the inner wall of the docking slot 10.

[0027] The material of the protective cushion layer 4 is rubber, the material of the shaping frame base layer 5 is polytetrafluoroethylene, the material of the reinforcement layer 6 is glass fiber, and the material of the outer protective layer 7 is polyurethane. The protective cushion layer 4 made of rubber can stably fit the cable surface, and has a good protective effect against friction damage. The shaping frame base layer 5 made of polytetrafluoroethylene and the reinforcement layer 6 made of glass fiber can make the entire bending shaping frame 2 structure stable and firm, so as to ensure that the entire structure is not prone to other deformations during use, thereby achieving stable shaping of the cable bending position, ensuring the smoothness of the cable bending, and reducing the occurrence of fractures due to hard bending. The outer protective layer 7 made of polyurethane has good structural stability, wear resistance and durability, and can effectively enhance the durability of the entire shaping frame.

[0028] The docking block 8 and the docking slot 10 are plug-in-matched, and the fixing protrusion 9 and the fixing groove 11 are nested. The outer surface of the fixing protrusion 9 and the inner wall of the fixing groove 11 are both arranged in an arc shape. There are two groups of docking block 8, fixing protrusion 9, docking slot 10, and fixing groove 11 structures, which are correspondingly located on the two sides of the first shaping frame 21 and the second shaping frame 22. When docking, the docking block 8 is inserted into the docking slot 10, and the arc surface of the fixing protrusion 9 will first contact the side opening position of the inner wall of the docking slot 10. By pressing, an extrusion effect is applied to it, and the fixing protrusion 9 will cooperate with the extrusion to deform and slide. When the docking block 8 is inserted into the docking slot 10, the fixing protrusion 9 is also stuck in the fixing groove 11, and the docking installation of the two shaping frames can be completed. The same principle can also be used to separate and disassemble the two.

[0029] A set of fixed mounting frames 12 are fixedly connected to the corresponding positions near the two ends of the first shaping frame 21 and the second shaping frame 22. Both sets of fixed mounting frames 12 are provided with fixed mounting holes 13. The coordinated setting of the fixed mounting frames 12 and the fixed mounting holes 13 can facilitate the positioning and fixed installation of the entire bending shaping frame 2. During installation, the bolts or screws used for fixing are passed through the fixed mounting holes 13 and nailed into the ground or the bottom plate to fix the fixed mounting frames 12, thereby realizing the fixing work of the bending shaping frame 2.

[0030] Working principle: When using a bending-resistant cable, the first shaping frame 21 and the second shaping frame 22 are connected to each other from both sides of the cable body 1, and the docking plug 8 is inserted into the docking slot 10. The arc surface of the fixed protrusion 9 will first contact the opening position of the inner wall side of the docking slot 10. By pressing, an extrusion effect is applied to it, and the fixed protrusion 9 will deform and slide in accordance with the extrusion. When the docking plug 8 is inserted into the docking slot 10, the fixed protrusion 9 is also stuck in the fixed groove 11. In this way, the docking is completed, forming a stable bending shaping frame 2, so that the cable body 1 can be stably covered in the positioning card slot 3, and the auxiliary bending work of the cable can be completed.
