[0002] Data cables are connecting cables used to transmit power or data. They are commonly used for charging and interconnecting electronic devices. Their applications include charging mobile phones, connecting computer peripherals, and data transmission between devices. They are widely used in consumer electronics, industrial equipment, and communications, and are a basic accessory of modern technology.
[0003] Current cable connection devices on the market are prone to fatigue fracture at the cable root when subjected to external forces, thus shortening the lifespan of the data cable. This is especially true when connecting to USB ports and other parts susceptible to external forces, where the bending and tensile stresses on the cable are more concentrated, further accelerating cable aging and damage.
[0004] Therefore, to address the above problems, a data cable with a breakage-resistant structure is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a data cable with a fracture-resistant structure, aiming to improve the problem that cables in the prior art are prone to fatigue fracture at the cable root when subjected to external forces.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A data cable with a break-resistant structure includes a cable, one end of which is fixedly connected to an break-resistant mechanism, the other end of which is provided with a USB interface, and the other end of the cable is fixedly connected to a plug;
[0008] The anti-breakage mechanism includes a connecting plate one and a connecting plate two. The opposite sides of the connecting plate one and the connecting plate two are respectively fixedly connected to one end of the cable and one end of the USB interface. An insulating soft shell is fixedly connected to the side of the connecting plate one and the connecting plate two. A fixed ball post one is fixedly connected to the other side of the connecting plate one. A steering ball post is rotatably connected to the other end of the fixed ball post one. A fixed ball post two is rotatably connected to the other end of the steering ball post. The other end of the fixed ball post two is fixedly connected to the other side of the connecting plate two.
[0009] As a further description of the above technical solution:
[0010] The first and second fixed ball piles are divided into spherical ends and routing ends, and both ends of the turning ball pile are spherical ends;
[0011] As a further description of the above technical solution:
[0012] The spherical ends of the fixed ball pile one, the turning ball pile and the fixed ball pile two are all semi-open, and the spherical ends of the fixed ball pile one, the turning ball pile and the fixed ball pile two are provided with spherical cavities.
[0013] As a further description of the above technical solution:
[0014] A through groove is provided between the first connecting plate, the second connecting plate, the first fixed ball pile, and the second fixed ball pile. The opening diameter of the spherical cavity is larger than the diameter of the through groove.
[0015] As a further description of the above technical solution:
[0016] Both the first connecting plate and the second connecting plate are provided with sealing rings on their outer sides. One sealing ring is provided at the connection between the first connecting plate and the cable, and the other sealing ring is provided at the connection between the second connecting plate and the USB interface.

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, when the cable is subjected to external force at the USB interface, the cable transmits the force to the steering ball through connecting plate one and connecting plate two. The steering ball rotates in multiple directions in the semi-open spherical cavity of the fixed ball. At the same time, the insulating soft shell provides elastic buffering to reduce rigid friction, and the sealing ring further prevents dust and moisture from entering, thereby achieving flexible buffering and protection of the cable. This effectively disperses external bending and tensile stress, reduces the possibility of fatigue fracture at the cable root, and significantly extends the service life of the data cable.
[0023] 2. In this utility model, the axial extensibility is enhanced by the transverse corrugated structure of the rubber shell, and the built-in spring further absorbs dynamic stress, effectively improving the cable's durability and impact resistance. Furthermore, the various components of the cable work together to provide excellent mechanical protection, conductivity, and anti-aging performance. Through multi-layer design and the application of tensile buffer materials, the cable can effectively disperse stress and reduce damage when subjected to external forces. The rigid support of the filler block further ensures the stability of the cable's internal structure and the fixation of the core, enabling the cable to maintain good working condition for a long time in dynamic environments.

[0030] 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.
[0031] Reference Figure 1The present invention provides an embodiment of a data cable with an anti-breakage structure, comprising a cable 1, an anti-breakage mechanism 2 fixedly connected to one end of the cable 1, a USB interface 3 provided at the other end of the anti-breakage mechanism 2, and a plug 4 fixedly connected to the other end of the cable 1. The anti-breakage mechanism 2 is used to convert the rigid connection between the cable 1 and the USB interface 3 into a segmented flexible connection to disperse stress concentration points.
[0032] Reference Figure 1 and Figure 2 The anti-breakage mechanism 2 includes a first connecting plate 201 and a second connecting plate 206. The opposite sides of the first connecting plate 201 and the second connecting plate 206 are respectively fixedly connected to one end of the cable 1 and one end of the USB interface 3. Both the first connecting plate 201 and the second connecting plate 206 have sealing rings 207 on their outer sides. One sealing ring 207 is located at the connection between the first connecting plate 201 and the cable 1, and the other sealing ring 207 is located at the connection between the second connecting plate 206 and the USB interface 3. The sealing rings 207 are made of silicone to prevent moisture and dust from entering the ball pile. An insulating soft shell 202 is fixedly connected to the adjacent side of the first connecting plate 201 and the second connecting plate 206. The insulating soft shell 202 wraps around the ball pile structure, providing secondary protection and enhancing overall flexibility. This, in conjunction with the sealing rings 207, maintains a seal when the cable 1 end rotates. Simultaneously, the elastic deformation of the insulating soft shell 202 further buffers the tensile force. A fixed ball post 203 is fixedly connected to the other side of the connecting plate 201. A steering ball post 204 is rotatably connected to the other end of the fixed ball post 203. A fixed ball post 205 is rotatably connected to the other end of the steering ball post 204. The two spherical ends of the steering ball post 204 are embedded in the cavity of the fixed ball post, forming a universal joint structure. The other end of the fixed ball post 205 is fixedly connected to the other side of the connecting plate. Thus, when the cable 1 bends, the steering ball post 204 rotates in multiple directions within the cavity, causing the fixed ball post to deflect synchronously, thereby achieving angle adjustment between the connecting plates.
[0033] Fixed ball pile 1 203 and fixed ball pile 205 are divided into spherical ends and cable routing ends. Both ends of the turning ball pile (204) are spherical ends. The spherical ends of fixed ball pile 1 203, turning ball pile 204 and fixed ball pile 205 are semi-open. The spherical ends of fixed ball pile 1 203, turning ball pile 204 and fixed ball pile 205 are provided with spherical cavities. A cable passage groove is provided between the connecting plate, fixed ball pile 1 203 and fixed ball pile 205. The opening diameter of the spherical cavity is larger than the opening diameter of the cable passage groove, thereby ensuring that the conductor has redundant space when the ball pile rotates. This allows the main body of cable 1 to bend freely in the cavity when cable 1 rotates, avoiding compression and breakage due to insufficient space.
[0034] Reference Figure 3 and Figure 4The cable 1 includes a rubber shell 101. The outer layer of the rubber shell 101 has a transverse corrugated structure, which provides axial flexibility for the cable 1. When stretched by external force, the corrugations expand to extend the length of the cable 1, reducing instantaneous tension. A spring 102 is installed inside the rubber shell 101 to absorb high-frequency vibration energy. The corrugated structure can withstand significant stretching, providing double protection to reduce fatigue damage. A shielding layer 103 is installed inside the rubber shell 101, and a braided layer 104 is installed inside the shielding layer 103. The braided layer 104 is used to prevent the cable 1 from being transversely cut or axially broken. A copper wire mesh 105 is installed inside the braided layer 104, surrounding the inner side of the braided layer 104 as a secondary tensile layer, improving the overall tensile strength of the cable 1. A thermally conductive layer 106 is provided on the inner side of the braided layer 104. Inside the thermally conductive layer 106, a filler block 107 is provided. The filler block 107 is a modified polyurethane foam material layer (using polyester polyurethane foam material SF-7025 produced by Changzhou Shangrui Polymer Materials Technology Co., Ltd., which has high resilience, tear resistance, abrasion resistance, oil resistance, and chemical corrosion resistance). After the modified polyurethane foam cures, it forms a rigid support network, thereby limiting the relative displacement of the wire cores 108 and preventing internal friction from causing filament breakage. The foam structure also reduces weight and improves flexibility. Multiple wire cores 108 are provided inside the filler block 107, with a gap of 0.2mm between the filler block 107 and the wire cores 108. This rigid support reduces fatigue fracture caused by relative displacement of the wire cores 108.
[0035] Working principle: Flexible buffering is achieved through the linkage structure of connecting plate 1 201, connecting plate 206, and the ball-and-pile. When cable 1 is subjected to bending or torsional forces, the steering ball-and-pile 204 rotates in multiple directions within the semi-open spherical cavity of the fixed ball-and-pile, allowing for angle adjustment between the connecting plates, thereby preventing stress from acting directly on the root of cable 1. The insulating soft shell 202 encloses the ball-and-pile structure, providing elastic buffering during rotation and reducing rigid friction, while the sealing ring 207 prevents dust and moisture intrusion, ensuring long-term reliability.
[0036] The cable 1 employs a multi-layered tensile and cushioning design. The transverse corrugated structure of the rubber shell 101 enhances axial flexibility, while the built-in spring 102 further absorbs dynamic stress. The shielding layer 103 and the braided layer 104 (such as Kevlar fiber) provide tensile and cut-resistant protection, while the copper wire mesh 105 enhances conductivity and assists in tensile strength. The thermally conductive layer 106 rapidly dissipates heat, preventing high temperatures from accelerating material aging. The filler block 107 uses modified polyurethane foam material, which, after curing, forms a rigid support network that precisely controls the gap between the wire cores 108, restricts the displacement of the wire cores 108, avoids wire breakage caused by internal friction, and allows the cable 1 to uniformly distribute stress under the rigid support of the filler block 107, reducing the possibility of single-point fatigue fracture.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
