Abstract
Description
Technical Field
[0001] This utility model relates to the field of data connection cable technology, and in particular to a bend-resistant data connection cable. Background Technology
[0002] Data cable connectors often experience outer sheath cracking and internal conductor breakage at the connection point between the connector and the cable body due to repeated plugging, unplugging, and bending. Current improvements often involve adding a molded protective sleeve at the junction of the data cable and the connector, increasing the thickness of the sleeve to enhance bending resistance. However, these improvements still have the following shortcomings in practical use: Although current bend-resistant data cables have been reinforced with thicker materials in areas prone to breakage, they still cannot solve the problem of small-angle bending caused by using a phone while charging. The reinforced and unreinforced areas will form new areas prone to bending, and repeated bending over a long period of time will still cause fatigue and cracking. Utility Model Content

[0004] The objective of this utility model is achieved through the following technical solution: a bend-resistant data cable, comprising a data cable body, both ends of which are fixedly connected to data plugs, the outer wall of the data cable body is surrounded by a highly elastic protective sleeve, a protective gel layer is filled between the inner wall of the highly elastic protective sleeve and the data plugs, the outer wall of the highly elastic protective sleeve is also surrounded by an elastic protective net, the outer wall of the highly elastic protective sleeve is also wrapped with an outer protective sleeve, the elastic protective net is located between the outer wall of the highly elastic protective sleeve and the inner wall of the outer protective sleeve, and a plurality of bending limiting baffles are fixedly connected to the outer wall of the outer protective sleeve.

[0007] Preferably, in any of the above embodiments, the outer protective sleeve is made of thermoplastic polyurethane elastic material, the inner wall of the outer protective sleeve is attached to the outer wall of the elastic protective net, and the material of the plurality of bending limiting baffles is the same as that of the outer protective sleeve and the two are integrally formed.
[0008] The technical effect achieved by adopting the above solution is that the thermoplastic polyurethane elastic material has both flexibility and rigidity, which can meet the bending requirements and provide a certain compressive support effect.
[0009] Preferably, in any of the above embodiments, the protective gel layer is made of silicone gel, the protective gel layer fills the space between the high-elasticity protective sleeve and the main body of the data cable, and the plurality of bending limiting baffles are all circular and are evenly distributed on the outer wall of the outer protective sleeve.
[0010] The technical effect achieved by adopting the above solution is that the silicone gel is a semi-fluid gel with excellent buffering, hydrophobicity and temperature resistance, which can effectively disperse stress from the weak point to the whole area.
[0011] Preferably, the high-elasticity protective sleeve is made of soft TPU material, as described in any of the above solutions.
[0012] The technical effect achieved by adopting the above solution is that TPU material has good elasticity and wear resistance, improving bending resistance and service life.
[0013] Preferably, in any of the above embodiments, the two ends of the elastic protective net are fixedly connected to the two ends of the data plug, the elastic protective net is made of aramid fiber, and the elastic protective net has a tubular structure.
[0014] The technical effects achieved by adopting the above solution are: aramid fibers have extremely high strength, are lightweight, and are resistant to high temperatures, which can greatly improve the tensile strength of the yarn.
[0015] This utility model has the following advantages: 1. This bend-resistant data cable absorbs and stores most of the bending energy through the controllable elastic deformation of its highly elastic protective sheath. It quickly returns to its original shape after the bending force disappears, thus avoiding plastic deformation and material fatigue, protecting the internal core from direct stress. The semi-fluid properties of the protective gel layer allow it to transform locally concentrated point stress into uniformly distributed surface stress. When the cable bends, the gel flows, effectively transferring and dispersing the pressure at the stress point throughout the entire filling area, thereby eliminating stress concentration points and preventing the sheath from cracking due to excessive stress at a single point. The tensile strength of the elastic protective mesh withstands most of the tensile force, preventing damage to the internal structure, limiting excessive outward expansion or twisting of the highly elastic protective sheath, and guiding its deformation towards safer and more uniform axial compression and extension, preventing local bulging or tearing, and distributing stress more evenly along the direction of the mesh.
[0016] 2. This bend-resistant data cable, through several bending limit baffles on the outside of the outer protective sleeve, can physically limit the data cable from excessive small-angle bending, forcing it to form a gentler and safer bending arc in the stronger cable body. This design not only ensures the flexibility required for daily use, but also actively avoids the most destructive bending scenarios, achieving a balance between protection and practicality.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0020] like Figures 1 to 3 As shown, a bend-resistant data cable includes a data cable body 4, with data plugs 2 fixedly connected to both ends of the data cable body 4. The outer wall of the data cable body 4 is surrounded by a highly elastic protective sleeve 5. A protective gel layer 6 is filled between the inner wall of the highly elastic protective sleeve 5 and the data plug 2. The outer wall of the highly elastic protective sleeve 5 is also surrounded by an elastic protective net 7. The outer wall of the highly elastic protective sleeve 5 is also wrapped with an outer protective sleeve 1. The elastic protective net 7 is located between the outer wall of the highly elastic protective sleeve 5 and the inner wall of the outer protective sleeve 1. Several bending limiting baffles 3 are fixedly connected to the outer wall of the outer protective sleeve 1.
[0021] As an optional technical solution of this utility model: the conductor part of the data cable body 4 is connected to the terminal of the data plug 2, and the two ends of the high elastic protective sleeve 5 and the outer protective sleeve 1 are fixedly connected to the outside of the two data plugs 2, thereby forming a complete enclosed protective structure.
[0022] As an optional technical solution of this utility model: the outer protective sleeve 1 is made of thermoplastic polyurethane elastic material, the inner wall of the outer protective sleeve 1 is attached to the outer wall of the elastic protective net 7, and a number of bending limiting baffles 3 are made of the same material as the outer protective sleeve 1 and the two are integrally formed. The thermoplastic polyurethane elastic material takes into account a certain degree of flexibility and rigidity, which can meet a certain degree of bending and provide a certain degree of compressive support effect.
[0023] As an optional technical solution of this utility model: the protective gel layer 6 is made of silicone gel, the protective gel layer 6 fills the space between the high elastic protective sleeve 5 and the data cable body 4, the several bending limiting baffles 3 are all circular, and the several bending limiting baffles 3 are evenly distributed on the outer wall of the outer protective sleeve 1. The silicone gel is semi-fluid gel, with excellent buffering, hydrophobicity and temperature resistance, and can effectively disperse stress from the weak point to the entire area.
[0024] As an optional technical solution of this utility model: the high elastic protective sleeve 5 is made of soft TPU material. TPU material has good elasticity and wear resistance, which improves bending resistance and service life.
[0025] As an optional technical solution of this utility model: the two ends of the elastic protective net 7 are fixedly connected to the two ends of the data plug 2. The elastic protective net 7 is made of aramid fiber and has a tubular structure. The elastic protective net 7 restricts the high elastic protective sleeve from excessively expanding or twisting outward, guides its deformation to safer and more uniform axial compression and extension, prevents local bulging or tearing, and distributes stress more evenly along the direction of the mesh. Aramid fiber has extremely high strength, is lightweight, and is resistant to high temperature, which can greatly improve the tensile strength of the wire.
[0026] In summary, this invention absorbs and stores most of the bending energy through the controllable elastic deformation of the highly elastic protective sleeve 5. When the bending force disappears, it quickly returns to its original shape, thus avoiding plastic deformation and material fatigue, protecting the internal core from direct stress. The semi-fluid nature of the protective gel layer 6 allows it to transform locally concentrated point stress into uniformly distributed surface stress. When the cable bends, the gel flows, effectively transferring and dispersing the pressure at the stress point throughout the filling area, thereby eliminating stress concentration points and preventing the sheath from cracking due to excessive stress at a single point. The elastic protective mesh also provides tensile strength. The tensile strength withstands most of the tensile force, preventing damage to the internal structure. It limits the excessive outward expansion or twisting of the highly elastic protective sleeve, guiding its deformation towards safer and more uniform axial compression and extension, preventing local bulging or tearing, and distributing stress more evenly along the direction of the network cable. Through several bending limit baffles 3 on the outside of the outer protective sleeve 1, it can physically limit the data cable from excessive small-angle bending, forcing it to form a smoother and safer bending arc in the stronger cable body. This design ensures the flexibility required for daily use while actively avoiding the most destructive bending scenarios, achieving a balance between protection and practicality.
