Description

Technical Field

[0001] This utility model relates to the field of ribbon cable technology, specifically a tear-resistant flexible flat ribbon cable. Background Technology

[0002] In the utility model patent application CN206322518U, published on July 11, 2017, entitled "Flexible Flat Cable", this utility model discloses a flexible flat cable, belonging to the field of flexible flat cable technology. The key technical point of the solution is a flexible flat cable, which includes an insulating layer, an adhesive layer, a conductor layer, an upper adhesive layer and an upper insulating layer stacked sequentially from bottom to top. The conductor layer has a number of parallel and separated silver-plated wires, and each silver-plated wire has exposed electrical contacts at both ends. This solves the problem of signal attenuation caused by decreased conductivity in the prior art, and has the effect of increasing conductivity and reducing the degree of signal attenuation.

[0003] In the aforementioned patents or prior art, when the existing flat ribbon cable is subjected to external force, the connecting layer between each group of wires is prone to tearing as the wires move. After long-term use, the torn ribbon cable is prone to twisting and overlapping, which can lead to the breakage of the internal cable core of the entire ribbon cable, thus causing connection and usage problems. Utility Model Content

[0004] The purpose of this invention is to provide a tear-resistant flexible flat cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tear-resistant flexible flat cable, comprising multiple sets of conductors, the outer surface of each conductor being covered with a sheath, both ends of each conductor being connected to a connector, an elastic component being provided between the sheaths, the elastic component comprising three sets of cross-designed elastic bands, and a protective component being provided on the outer surface of the sheath.

[0006] Furthermore, the protective assembly includes a protective sleeve covering multiple sets of outer surfaces of the foreskin, and multiple sets of fixing components are fitted onto the protective sleeve.

[0007] Furthermore, the fixing component includes multiple sets of fixing sleeves fitted onto the protective sleeve, and the fixing sleeves are provided with limiting components.

[0008] Furthermore, the limiting component includes multiple sets of extrusion blocks arranged in an array on the inner wall of the fixed sleeve.

[0009] Furthermore, the outer casing has a multi-layer design, consisting of an insulating layer, an elastic layer, a reinforcing layer, and a wear-resistant layer from the inside out.

[0010] Furthermore, the wear-resistant layer is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this tear-resistant flexible flat cable is reasonable and has the following advantages:

[0012] (1) The tear-resistant flexible flat cable significantly improves the mechanical strength and tear resistance of the cable through external elastic and protective components. The elastic components include three sets of cross-designed elastic bands, which can increase tensile strength when the cable is stretched. The cross-design structure can form a mesh support structure, and its tensile strength can disperse axial tension. When the cable is stretched laterally, the cross angle of the elastic bands will adaptively adjust, transforming concentrated stress into multi-directional distribution, avoiding local breakage, and thus enhancing the structural stability of the entire cable. This design makes the cable more resistant to tearing when subjected to physical stretching or compression. In addition to reducing wear and tear, the protective sleeve and fixing components wrapped around the outer surface of the foreskin further enhance the overall performance of the ribbon cable, improve its mechanical strength, and make it more resistant to tearing and wear. Especially when subjected to physical pulling or compression, the fixing components can fix the protective sleeve through the design of the fixing sleeve and the compression block. The protective sleeve and the fixing sleeve adopt a "nested limiting" design. The array of compression blocks on the inner wall of the fixing sleeve is precisely embedded in the foreskin gap, and radial pressure is generated through interference fit to prevent the protective sleeve from slipping. This design not only improves the durability of the ribbon cable, but also enhances its safety and reduces the risk of failure caused by ribbon cable damage. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-6 The present invention provides a technical solution as follows:

[0022] Example 1:

[0023] A tear-resistant flexible flat cable includes multiple sets of conductors 100, the outer surface of each conductor 100 is covered with a sheath 101, both ends of each conductor 100 are connected to a connector 102, an elastic component is provided between the sheaths 101, the elastic component includes three sets of cross-designed elastic bands 103, and a protective component is provided on the outer surface of the sheath 101.

[0024] The protective component includes a protective sleeve 104 covering the outer surface of multiple sets of foreskin 101, and multiple sets of fixing components are fitted on the protective sleeve 104.

[0025] The fixing component includes multiple sets of fixing sleeves 105 sleeved on the protective sleeve 104, and the fixing sleeve 105 is provided with a limiting component.

[0026] The limiting component includes multiple sets of extrusion blocks 106 arranged in an array on the inner wall of the fixed sleeve 105.

[0027] The outer sheath 101 has a multi-layer design, consisting of an insulating layer 1010, an elastic layer 1011, a reinforcing layer 1012, and a wear-resistant layer 1013 from the inside out.

[0028] The wear-resistant layer 1013 has anti-slip textures.

[0029] Working Principle: During use, the conductor 100 is protected by the sheath 101. The sheath 101 has a multi-layer design. The insulation layer 1010 is designed to isolate adjacent conductors 100, preventing current leakage and short circuits, ensuring the accuracy and safety of signal transmission, improving electrical insulation performance, preventing signal interference, and enhancing the reliability of the ribbon cable. The elastic layer 1011 is usually made of an elastic material, such as polyurethane or silicone rubber. It can absorb stress caused by bending or twisting, protecting the internal conductor 100 and insulation layer 1010, improving the flexibility and durability of the ribbon cable, allowing it to be used for a long time without damage in environments with frequent bending or twisting. The reinforcing layer 1012 is usually made of glass fiber or other reinforcing materials. It provides additional mechanical strength, preventing the ribbon cable from breaking or deforming under external force, enhancing the mechanical strength and durability of the ribbon cable, and enabling it to withstand greater tensile or compressive forces. It is suitable for applications requiring high mechanical strength. The wear-resistant layer 1013 is usually made of wear-resistant materials, such as Teflon PTFE or other materials. This high-performance polymer protects the cable from friction, wear, and chemical corrosion, improving its abrasion resistance and chemical stability, and extending its service life. The sheath 101, through its multi-layered structure design, comprehensively enhances the cable's performance in all aspects, increasing durability and safety. The outer surface of the sheath 101 is also wrapped with a layer for protection, improving the cable's mechanical strength and making it more resistant to tearing and abrasion, especially under physical tension or compression. The elastic band 103, in conjunction with the sheath 101, increases its tensile strength when stretched. The elastic band 103 also limits the sheath 101, preventing relative displacement under external force, thus enhancing the overall structural stability of the cable. The outer surface of the protective sleeve 104 is fitted with multiple fixing sleeves 105, which secure the protective sleeve 104 and prevent displacement under external force. The fixing sleeves 105 also provide compression fixation. Compression blocks 106 correspond to the gaps between every two sheaths 101, compressing the gaps to ensure a more secure fixation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
