[0002] Equipment connection cables are cables used to connect various interfaces of electronic devices, mainly to realize signal transmission, data exchange and power supply functions.

[0003] Existing mobile device connection cables have significant shortcomings in terms of portability, durability, and compatibility. Traditional connection cables have poor bending resistance and are prone to internal wire breakage or shielding damage after frequent bending, resulting in charging interruption or data transmission failure. In addition, conventional connection cables use ordinary copper cores, which are prone to increased resistance due to oxidation, and the outer sheath is mostly made of PVC material, which is prone to aging and cracking after long-term use, and has poor resistance to oil stains and high temperatures.

[0004] To address this, a bend-resistant, ultra-compact mobile device connection cable is proposed. Utility Model Content

Traditional connection cables have poor bend resistance and are prone to internal wire breakage or shielding layer damage after frequent bending, resulting in charging interruption or data transmission failure. In addition, conventional connection cables use ordinary copper cores, which are prone to increased resistance due to oxidation, and the outer sheath is mostly made of PVC material, which is prone to aging and cracking after long-term use, and has poor resistance to oil stains and high temperatures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending-resistant ultra-compact mobile device connection cable, comprising a cable body and a connector, wherein the cable body and the connector are fixedly connected, and the cable body comprises a conductor, a shielding layer, an insulation layer and an outer sheath, wherein the conductor, shielding layer, insulation layer and outer sheath are arranged sequentially from the inside to the outside.

Detailed Implementation

[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 1-3 The present invention provides the following technical solution:

[0022] A bend-resistant, ultra-compact mobile device connection cable includes a cable body 1 and a connector 2. The cable body 1 and the connector 2 are fixedly connected. The cable body 1 includes a conductor 3, a shielding layer 4, an insulation layer 5, and an outer sheath 6. The conductor 3, shielding layer 4, insulation layer 5, and outer sheath 6 are arranged sequentially from the inside to the outside.

[0023] In this embodiment, the cable body 1 adopts a layered structure consisting of conductors 3, shielding layer 4, insulation layer 5, and outer sheath 6, achieving synergistic functions of power transmission, anti-interference, insulation protection, and physical protection. Each layer is tightly integrated from the inside out, ensuring signal stability through shielding layer 4 and providing mechanical protection through outer sheath 6. The overall structure is compact and functionally complete. The combination of fluororubber insulation layer 5 and TPU outer sheath 6 provides resistance to high and low temperatures, aging, and oil stains, solving the problem of easy cracking of traditional PVC outer sheaths. The conductors 3, made of silver-plated copper wire, reduce oxidation and maintain stable conductivity. Moreover, the double-layer shielding structure of aluminum-magnesium alloy braided mesh 41 and aluminum foil 42 effectively blocks electromagnetic interference, ensuring stable data transmission and charging. Therefore, the volume of the cable body 1 is reduced by ultra-fine conductors 3 and multi-layer compact design. The transition part 8 at the connection between the cable body 1 and the connector 2 is integrally injection molded, and with the Kevlar fiber reinforcement layer 7, bending stress is dispersed, preventing damage to the internal conductors 3 and shielding layer 4 due to frequent bending, thus solving the problems of loose structure and single function of traditional connecting wires.

[0024] Specifically, such as Figure 2 As shown, conductor 3 is a stranded structure of ultra-fine silver-plated copper wire.

[0025] Specifically, such as Figure 3 As shown, the shielding layer 4 includes an aluminum-magnesium alloy wire mesh and an aluminum foil 42, and the aluminum-magnesium alloy wire mesh 41 has a coverage of ≥90%.

[0026] In this embodiment: the conductor 3 adopts an ultra-fine silver-plated copper wire stranded structure. The ultra-fine design improves the flexibility of the conductor 1, making it easy to bend and store. The silver plating layer reduces copper core oxidation, maintains stable long-term conductivity, and avoids the problems of increased resistance and decreased charging efficiency caused by oxidation of traditional ordinary copper cores. The stranded structure disperses the force on a single conductor 3, further enhancing its resistance to bending. The aluminum-magnesium alloy wire braided mesh of the shielding layer 4 and the aluminum foil 42 form a double layer of protection. The aluminum foil 42 can block high-frequency electromagnetic interference, and the high-coverage braided mesh effectively shields low-frequency interference. The two work together to ensure that the signal is not affected by external interference during data transmission, avoiding transmission interruption or data packet loss, which is especially suitable for high-speed data exchange scenarios.

[0027] Specifically, such as Figure 2 As shown, the insulating layer 5 is made of fluororubber, the outer sheath 6 is made of TPU elastomer, and the surface is provided with anti-slip micro-texture.

[0028] Specifically, such as Figure 3As shown, a reinforcing layer 7 is provided between the conductor 3 and the shielding layer 4, and the reinforcing layer 7 is made of Kevlar fiber.

[0029] In this embodiment: the fluororubber insulation layer 5 possesses excellent high and low temperature resistance and insulation properties, adapting to complex environments (such as high-temperature vehicle use and low-temperature outdoor use), preventing internal short circuits in the cable 1; the outer sheath 6, composed of TPU elastomer, is flexible and wear-resistant, with anti-slip micro-textures on its surface enhancing grip comfort and preventing slippage, while its oil-resistant properties facilitate daily cleaning, solving the problems of easy aging and poor stain resistance of traditional PVC outer sheaths; by setting a reinforcing layer 7, composed of Kevlar fiber, located between the conductor 3 and the shielding layer 4, its high strength enhances the overall tensile strength of the cable 1, preventing the internal conductor 3 from breaking due to accidental pulling. At the same time, the reinforcing layer 7 can buffer stress during bending, reducing wear on the conductor 3 and shielding layer 4, extending the cable's service life, especially suitable for frequent carrying and moving usage scenarios.

[0030] Specifically, such as Figure 1 As shown, the outer shell of connector 2 is made of magnesium-aluminum alloy die casting, and its internal terminals are made of gold-plated phosphor bronze.

[0031] Specifically, such as Figure 1 As shown, a transition part 8 is provided at the connection between the connector 2 and the line body 1, and the transition part 8 is integrally injection molded with the outer sheath 6.

[0032] In this embodiment: the outer shell of connector 2 is made of magnesium-aluminum alloy die-casting, which combines lightweight and high strength, and its drop and impact resistance is better than that of traditional plastic shells. The internal terminals are made of gold-plated phosphor bronze. The gold plating reduces contact resistance and ensures efficient and stable charging and data transmission. The elastic properties of phosphor bronze ensure that the terminals can still maintain tight contact after long-term insertion and removal, avoiding functional failure caused by poor contact. The transition part 8 at the connection between connector 2 and wire 1 is integrally injection molded with the outer sheath 6, making the transition area smooth and without sharp edges, dispersing the stress during bending and avoiding the stress concentration problem caused by traditional right-angle transitions. The integral molding structure also enhances the connection strength between connector 2 and wire 1, preventing them from separating, while improving waterproof and dustproof performance and protecting the internal structure from corrosion.

[0033] Working Principle: When used in the device connection cable, the cable body 1 adopts a layered structure of conductor 3, shielding layer 4, insulation layer 5, and outer sheath 6 to achieve the coordinated functions of power transmission, anti-interference, insulation protection, and physical protection. Each layer is tightly combined from the inside out. The shielding layer 4 ensures signal stability, while the outer sheath 6 provides mechanical protection. The overall structure is compact and functionally complete. The combination of fluororubber insulation layer 5 and TPU outer sheath 6 is resistant to high and low temperatures, aging, and oil stains, solving the problem of easy cracking of traditional PVC outer sheaths. The conductor 3, made of silver-plated copper wire, reduces oxidation and maintains stable conductivity. Moreover, the double-layer shielding structure of aluminum-magnesium alloy braided mesh 41 and aluminum foil 42 effectively blocks electromagnetic interference, ensuring stable data transmission and charging. Therefore, the volume of the cable body 1 is reduced by ultra-fine conductor 3 and multi-layer compact design. The transition part 8 at the connection between the cable body 1 and the connector 2 is integrally injection molded and reinforced with Kevlar fiber layer 7 to disperse bending stress and prevent damage to the internal conductor 3 and shielding layer 4 due to frequent bending, solving the problems of loose structure and single function of traditional connection cables.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
