Description

Technical Field

[0001] This utility model relates to the field of data cable technology, and in particular to a data cable with wire harness protection to prevent breakage. Background Technology

[0002] With the widespread use of portable electronic devices such as smartphones, tablets, and laptops, data cables, as core accessories for device charging and data transmission, have seen a significant increase in usage frequency and reliance. Currently, most data cables on the market consist of a connector (including metal terminals), a cable body (containing multiple conductor bundles), and an outer insulating sheath. The conductor bundles are typically made of copper cores, carrying current and signal transmission functions, while the outer insulating sheath is mostly made of elastic materials such as PVC or TPE, providing basic protection.

[0003] However, existing data cables have a significant fragility defect in actual use, with the connector-to-cable connection prone to breakage. This area is where the data cable experiences the most concentrated stress, and frequent bending (such as when the device moves during charging causing the cable to rotate around the connector) and pulling (such as when the data cable is accidentally dragged) during daily use can cause fatigue damage to the insulation sleeve at the connection. Existing structures often use a single injection molding process to fix the connector to the cable, resulting in insufficient bonding strength between the injection molding layer and the cable insulation sleeve. Under prolonged stress, cracks or even peeling can easily occur, exposing the internal conductor bundle and subsequently causing the solder joints between the conductors and the connector terminals to detach, leading to charging interruptions or data transmission failures. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the ends of data cables in the prior art are prone to breakage. To address this, we propose a breakage-resistant data cable with wire harness protection.

[0005] To achieve the above objectives, this application adopts the following technical solution: a data cable with wire harness protection for breakage, comprising a data cable body, with ports at both ends of the data cable body, and end caps fixedly connected to the tails of the ports. A protective component is provided between the end caps and the data cable body, the protective component comprising two sets of connecting rings, each set having two connecting rings, one connecting ring sleeved on the surface of the end cap, and the other connecting ring sleeved on the surface of the data cable body. Multiple telescopic springs are provided between the two connecting rings, and multiple mounting grooves are formed in the inner wall of the connecting rings. Fixed cylinders are fixedly connected to both sides of the inner wall of the mounting grooves, and rotating rollers are built into the fixed cylinders. The two ends of the rotating rollers are rotatably connected to the bottom of the inner cavities of the two fixed cylinders. Coil springs are sleeved at both ends of the rotating rollers, and a moving seat is fixedly sleeved on the surface of the rotating rollers.

[0006] Preferably, a corrugated pipe is sleeved between the two connecting rings.

[0007] Preferably, the inner diameters of the two connecting rings in each group are different.

[0008] Preferably, the plurality of the telescopic springs are evenly distributed around the axis of the connecting ring.

[0009] Preferably, the two connecting rings have multiple positioning grooves on their end faces that are close to each other, and the two ends of the telescopic spring are respectively fixedly connected to the bottom of the positioning groove cavity of the two connecting rings.

[0010] Preferably, a plug is inserted into one end of the port.

[0011] Preferably, one end of the coil spring is fixedly connected to the rotating roller, and the other end of the coil spring is fixedly connected to the inner wall of the fixed cylinder.

[0012] Preferably, the end of the motion seat away from the rotating roller has a plurality of evenly distributed teeth.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The present invention includes a data cable body with ports at both ends, a terminal connected to the end of the port, and a plug inserted into one end of the port. The protective structure is a protective component between the terminal and the data cable body.

[0015] The protective assembly includes two sets of connecting rings (two rings in each set, one for attaching to the end and the other to the data cable body, forming a transition structure due to differences in inner diameter), multiple telescopic springs evenly distributed around the axis, and a bellows. Under stress, the telescopic springs disperse the stress generated by bending and pulling through elastic deformation, preventing stress concentration at the insulating sleeve at the connection point. The positioning grooves on the end faces of the connecting rings fix the springs, preventing them from shifting or falling off. The bellows can wrap around the connection area to prevent friction and collision, and its good flexibility does not affect the normal bending of the data cable. It also helps support the injection-molded layer, reducing the risk of it peeling off from the insulating sleeve.

[0016] Inside the mounting groove on the inner wall of the connecting ring, a rotating roller is built into the fixed cylinder. Coil springs are fitted at both ends of the roller, and the roller surface is connected to a toothed moving seat. The coil springs store force, causing the moving seat to fit tightly against the end or body surface, while the teeth slightly mesh, firmly fixing the connecting ring in place, preventing slippage, and ensuring precise protection.

[0017] The overall device uses springs to disperse stress and corrugated pipes for protection and support, which can prevent fatigue cracking of the insulation sleeve and peeling of the injection molding layer from the insulation sleeve. It also avoids exposure of the internal wire harness and detachment of the wires from the connector terminals, solving the problems of charging interruption or data transmission failure, and greatly improving the reliability of the data cable.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Reference Figures 1 to 5As shown, this utility model provides a technical solution: a data cable with wire harness protection to prevent breakage, including a data cable body 1, with ports 101 at both ends of the data cable body 1, and end caps 102 fixedly connected to the tail of the ports 101. A plug 2 is inserted into one end of the port 101, and a protective component 3 is provided between the end cap 102 and the data cable body 1. The protective component 3 includes two sets of connecting rings 301, with two connecting rings 301 in each set. One connecting ring 301 is sleeved on the surface of the end cap 102, and the other connecting ring 301 is sleeved on the surface of the data cable body 1. The inner diameters of the two connecting rings 301 in each set are different. Multiple telescopic springs 302 are provided between the connecting rings 301. The multiple telescopic springs 302 are evenly distributed around the axis of the connecting rings 301. Multiple positioning grooves 303 are opened on the end faces of the two connecting rings 301 that are close to each other. The two ends of the telescopic springs 302 are fixedly connected to the bottom of the inner cavity of the positioning grooves 303 of the two connecting rings 301 respectively. A corrugated tube 304 is sleeved between the two connecting rings 301. The two sets of connecting rings 301 in the protective assembly 3 are adapted to the end 102 and the data cable body 1 respectively. Because the inner diameters of the two sets of connecting rings 301 are different, a transition structure is formed at the connection between the end 102 and the data cable body 1. When the data cable is subjected to bending force (such as the cable rotating around the connector due to device movement during charging) or pulling force (such as accidental dragging), the telescopic springs 302 between the connecting rings 301 will undergo elastic deformation. When bending, the springs will stretch or compress accordingly according to the bending direction. When pulling, the springs will absorb part of the pulling force through stretching, thereby dispersing the stress originally concentrated at the connection between the end 102 and the data cable body 1 to multiple springs, preventing stress from acting directly on the insulating sleeve at the connection. At the same time, the positioning groove 303 on the end face of the connecting ring 301 can accurately fix the two ends of the telescopic springs 302, preventing the springs from shifting or falling off during the force process, ensuring that the springs can always stably play a buffering role, and reducing fatigue damage to the insulating sleeve at the connection caused by stress concentration.

[0027] The corrugated tube 304, which is sleeved between the two connecting rings 301, can completely wrap the connection area between the end 102 and the data cable body 1, forming a physical protective barrier to prevent external friction and collision from directly damaging the insulating sleeve at the connection. On the other hand, the corrugated tube 304 itself has good flexibility and can bend synchronously with the slight movement of the connecting rings 301 and the deformation of the spring. It does not restrict the normal bending action of the data cable, and can further disperse the local stress at the connection, preventing the insulating sleeve from cracking due to long-term exposure or repeated bending. At the same time, it can also provide auxiliary support for the easily peelable injection molding layer in the existing structure, reducing the risk of peeling between the injection molding layer and the insulating sleeve.

[0028] Furthermore, multiple mounting grooves 305 are formed on the inner wall of the connecting ring 301. Fixed cylinders 306 are fixedly connected to both sides of the inner wall of the mounting grooves 305. Rotating rollers 307 are housed inside the fixed cylinders 306. The two ends of the rotating rollers 307 are rotatably connected to the bottom of the inner cavities of the two fixed cylinders 306. Coil springs 308 are sleeved on both ends of the rotating rollers 307. One end of the coil spring 308 is fixedly connected to the rotating rollers 307, and the other end is fixedly connected to the inner wall of the fixed cylinders 306. A moving seat 309 is fixedly sleeved on the surface of the rotating rollers 307. The end of the moving seat 309 furthest from the rotating rollers 307 has a... The spring 308 has multiple evenly distributed teeth 310. It applies a continuous torque to the rotating roller 307 by storing its own force, which drives the moving seat 309 on the surface of the rotating roller 307 to always be in close contact with the end 102 or the data cable body 1. The teeth 310 on the moving seat 309 form a slight engagement with the surface of the end 102 and the data cable body 1, thereby firmly fixing the connecting ring 301 to the end 102 and the data cable body 1, completely preventing the connecting ring 301 from sliding or shifting on the surface of the end 102 or the data cable body 1, and ensuring that the protective component 3 always accurately covers the connection point.

[0029] The device reduces the direct impact of bending and pulling on the connection point by the stress dispersion effect of the telescopic spring 302, thus avoiding fatigue cracking of the insulating sleeve. The corrugated tube 304 provides protection and the injection molding layer provides auxiliary support, which can effectively prevent the injection molding layer from peeling off from the insulating sleeve. This avoids the exposure of the internal wire harness and the detachment of the wires from the connector terminals. It fundamentally solves the problem of charging interruption or data transmission failure caused by breakage in the existing structure, and significantly improves the reliability of the data cable.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
