Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a bending-resistant cable. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for control installation, equipment connection, and power transmission. They are a common and indispensable tool in daily life. In actual use, cables are often bent and rolled. When the bending arc is large, the cable is prone to breakage and damage. Moreover, the protection of the internal copper core of existing cables is generally poor, and the bending resistance is generally average.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a bending-resistant cable to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A bending-resistant cable includes an outer sheath and a main core, the main core being disposed within the outer sheath, a secondary core being disposed on the main core, the secondary core being wrapped with a first insulating and fireproof layer, an anti-bending mechanism being fixedly disposed within the outer sheath, the anti-bending mechanism including an elastic layer and an elastic inner core, the elastic layer being fixedly disposed within the inner side of the outer sheath, the elastic inner core being disposed within the elastic layer, and a protective mesh frame being fixedly disposed within the inner side of the elastic layer.

[0007] Furthermore, the secondary core is provided in multiple sets, and the multiple sets of secondary cores are evenly wrapped around the main core.

[0008] Furthermore, the protective mesh frame is composed of multiple sets of circular rings and strips.

[0009] Furthermore, a second insulating fireproof layer is fixedly installed on the inner side of the protective mesh frame to improve the insulation and fireproof performance of the cable.

[0010] Furthermore, a protective layer is fixedly provided on the inner side of the second insulating fireproof layer, and the protective layer is wrapped around the first insulating fireproof layer to improve the insulation and fireproof performance of the cable.

[0011] Furthermore, a protective mesh is fixedly provided inside the outer skin, and the protective mesh is wrapped around the elastic layer to improve the anti-cut effect.

[0012] Furthermore, a fixing ring is fixedly provided on the outer sheath to facilitate the positioning and fixing of the cable.

[0013] Furthermore, multiple sets of fixing rings are provided, and the multiple sets of fixing rings are evenly distributed at the ends of the outer skin.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) By setting up an elastic layer, an elastic inner core and a protective mesh frame, when the cable is bent, the elastic layer and elastic inner core on the inner side of the bend are compressed and the elastic layer and elastic inner core on the outer side of the bend are stretched. At the same time, the protective mesh frame prevents the main core and secondary core on the inner side from bending too much. After the external force on the cable disappears, the elastic layer and elastic inner core are reset, which effectively improves the bending resistance of the cable and has strong practicality.

[0016] (2) By setting a first insulating fireproof layer, a protective layer and a second insulating fireproof layer, the first insulating protective layer and the second insulating protective layer improve the insulation protection effect of the cable when using the anti-bending cable, and effectively improve the fireproof effect, with strong functionality.

[0017] (3) By setting up a protective wire mesh and a fixing ring, the protective wire mesh effectively enhances the cable's resistance to knife cuts when the cable is connected to the equipment. The fixing ring makes it easy to fix the position of the cable after the cable is connected. It is highly flexible and practical. Attached Figure Description

[0025] Example

[0026] See appendix Figure 1-3 A type of flexurally resistant cable includes an outer sheath 1 and a main wire core 2, wherein,

[0027] The main wire core 2 is disposed inside the outer sheath 1, and a secondary wire core 3 is disposed on the main wire core 2. A first insulating and fireproof layer 4 is wrapped around the secondary wire core 3. An anti-bending mechanism is fixedly disposed inside the outer sheath 1.

[0028] The anti-bending mechanism includes an elastic layer 5 and an elastic inner core 6. The elastic layer 5 is fixedly disposed inside the outer sheath 1, and the elastic inner core 6 is disposed inside the elastic layer 5. A protective mesh frame 7 is fixedly disposed inside the elastic layer 5. Multiple sets of secondary cores 3 are provided, and the multiple sets of secondary cores 3 are evenly wrapped around the main core 2. The protective mesh frame 7 is composed of multiple sets of rings and strips.

[0029] When using anti-bending cables, when the cable is bent, the elastic layer 5 and elastic core 6 on the inner side of the bend are compressed, while the elastic layer 5 and elastic core 6 on the outer side of the bend are stretched. At the same time, the protective mesh frame 7 prevents the main core 2 and auxiliary core 3 on the inner side from bending too much, effectively improving the cable's anti-bending performance and making it highly practical.

[0030] See Figure 1 and Figure 2 A bending-resistant cable includes an outer sheath 1 and a main core 2. The main core 2 is disposed inside the outer sheath 1, and a secondary core 3 is disposed on the main core 2. A first insulating and fireproof layer 4 is wrapped around the secondary core 3. A bending-resistant mechanism is fixedly disposed inside the outer sheath 1. The bending-resistant mechanism includes an elastic layer 5 and an elastic inner core 6.

A protective mesh frame 7 is fixedly disposed inside the elastic layer 5, and a second insulating and fireproof layer 8 is fixedly disposed inside the protective mesh frame 7. A protective layer 9 is fixedly disposed inside the second insulating and fireproof layer 8, and the protective layer 9 is wrapped around the first insulating protective layer 9.

[0031] When using anti-bending cables, the first insulation layer 9 and the second insulation layer 9 improve the insulation protection effect of the cable and effectively enhance the fire resistance, making it highly functional.

[0032] Please see Figure 1 , Figure 2 and Figure 4 A protective wire mesh 10 is fixedly installed inside the outer skin 1. The protective wire mesh 10 is wrapped around the elastic layer 5. A fixing ring 11 is fixedly installed on the outer skin 1. Multiple sets of fixing rings 11 are provided and the multiple sets of fixing rings 11 are evenly distributed at the ends of the outer skin 1.

[0033] Specifically, when connecting equipment via cables, the protective wire mesh 10 effectively enhances the cable's resistance to cuts, and the fixing ring 11 facilitates fixing the cable's position after the connection is completed, offering high flexibility and strong practicality.

[0034] In summary, when using the anti-bending cable of this embodiment, when the cable is bent, the elastic layer 5 and elastic core 6 on the inner side of the bend are compressed, while the elastic layer 5 and elastic core 6 on the outer side of the bend are stretched. Simultaneously, the protective mesh frame 7 prevents excessive bending of the inner main core 2 and auxiliary core 3, effectively improving the cable's anti-bending performance and making it highly practical. The first and second insulating protective layers 9 enhance the cable's insulation protection and effectively improve fire resistance, demonstrating strong functionality. When connecting equipment via the cable, the protective mesh 10 effectively strengthens the cable's resistance to knife cuts, and the fixing ring 11 facilitates fixing the cable's position after connection, offering high flexibility and practicality.
