It plays a vital role in the assembly of the charging cable and also increases the service life of the charging connection cable 2.

[0025] The winding protective sleeve 5 is in a spiral shape, and the thickness of the spiral body of the winding protective sleeve 5 along the spiral direction changes at uniform alternating intervals. The winding protective sleeve 5 is covered on the charging connection line 2 in a spiral shape, which can effectively protect the connection line from bending, stretching and other external damage. Due to the spiral shape, it can also provide a certain flexibility, making the connection line more durable when bent. The uniform alternating interval change of the thickness of the spiral body can provide a uniform support force, ensuring that the force distribution of the connection line is uniform during use, reducing the local pressure on the connection line, and helping to prevent damage. The spiral design makes the winding protective sleeve 5 have a certain elasticity and flexibility, adapting to the bending and stretching of the connection line, and does not affect the flexibility and operability of the connection line. The spiral appearance design not only has practical functions, but also makes the connection line look neater and more beautiful. One end is connected to the safety buckle 4 to ensure the stability of the connection. This is used in conjunction with the safety buckle 4 to make the entire connection system more reliable.

[0026] The USB connector protection component 6 includes a fixed plate 601, a through-port 602, a sliding plate 603, an arc block 604, a bolt 605, and a protective pad 606. The outer surface of the USB connector 1 is fixedly connected with a symmetrical fixed plate 601, and the fixed plate 601 is used to firmly fix the USB connector 1 on the charging connection line 2 to prevent it from being torn off. The opposite surfaces of the two fixed plates 601 are provided with through-ports 602, and the through-ports 602 are used to connect the openings 401 of other components. The insides of the two through-ports 602 are provided with sliding plates 603, and the sliding plates 603 are used to provide sliding support between components to ensure that the various parts of the USB connector protection component 6 can slide relative to each other. The side surfaces of the two sliding plates 603 that are close to each other are fixedly connected with arc blocks 604, and the arc blocks 604 are used to provide additional support and stability Qualitatively, the design of the arc block 604 helps to prevent the USB connector 1 from being pulled and disconnected from the charging cable 2 during use. The inner bottom walls of the two through holes 602 are provided with threaded holes, which are used to connect fixing bolts 605, so that the components of the USB connector 1 can be fixed by bolts 605 to increase the firmness of the connection. The inner walls of the two threaded holes are threadedly connected with fixing bolts 605, and the fixing bolts 605 are connected in the threaded holes to ensure that they will not loosen or fall off. The side surfaces of the two arc blocks 604 that are close to each other are fixedly connected with protective pads 606. The protective pads 606 provide additional protection to prevent the charging cable 2 from being damaged by external impact and friction and provide a buffering effect for the arc block 604. The side surfaces of the two protective pads 606 that are close to each other are in contact with the outer surface of the charging cable 2.

[0027] The bottom surfaces of the two sliding plates 603 are provided with fixing holes for installing fixing bolts 605. The tops of the two fixing bolts 605 are provided with fixing pads, which are in contact with the inner top walls of the fixing holes to provide additional support and stability. The upper surfaces of the two fixing pads are in contact with the inner top walls of the two fixing holes. The inner top walls of the two through openings 602 are fixedly connected with compression pads, which provide pressure and support to ensure that the top of the sliding plate 603 can slide well. The two sliding plates 603 The upper surfaces of the two sliding plates 603 are in contact with the bottom surfaces of the two extrusion pads, and the upper surfaces of the two sliding plates 603 and the bottom surfaces of the two sliding plates 603 are connected to two reinforcement blocks. The presence of the reinforcement blocks strengthens the structural stability of the sliding plates 603 and improves the durability and reliability of the entire USB connector protection assembly 6. The side surfaces of the two groups of reinforcement blocks that are close to each other are fixedly connected to the side surfaces of the two arc blocks 604 that are away from each other. The reinforcement blocks can provide additional support and stability to prevent loosening and detachment between the sliding plates 603 and the arc blocks 604.

[0028] The length of the winding protective sleeve 5 is 3 to 6 cm, and the number of turns of the winding protective sleeve 5 is 6 to 12 turns, which can effectively reduce the damage to the connecting line due to bending, twisting or stretching, and extend the service life of the connecting line. The spiral design gives the winding protective sleeve 5 a certain elasticity, so that the connecting line can better return to its original shape when bent, reduce the pressure on the connecting line, and improve the durability of the connecting line.

[0029] When in use, first, we need to open the circular ring part of the safety buckle 4, insert the charging connection cable 2 into the opening 401, and ensure that the connection cable is fixed in the circular ring. This can ensure that the connection cable and the safety buckle 4 are firmly connected and provide additional support to prevent the connection from loosening or disconnecting. Next, the winding protective cover 5 is spirally covered on the charging connection cable 2 to ensure that the entire length of the connection cable is covered. The spiral design provides all-round protection and reduces damage to the connecting line caused by bending, stretching, etc. Then, the USB connector protection component 6 is installed and installed between the USB connector 1 and the charging connecting line 2. Through the through-hole 602 set on the fixing plate 601, the sliding plate 603 can slide flexibly and can drive the arc block 604 to move its position. By using the two arc blocks 604 approaching each other, the outside of the charging connecting line 2 is firmly extruded and positioned. At the same time, by designing the threaded hole and matching it with the fixing bolt 605, the sliding plate 603 is firmly fixed after moving inside the through-hole 602, and the support of the sliding plate and the arc block 604 to the outside of the charging connecting line 2 is strengthened, making it more firm, and also reducing the pressure between the charging connecting line 2 and the USB connector 1, significantly improving the tensile strength of the mobile phone charging line, helping to avoid the problem of the charging connecting line 2 breaking due to pulling during use, thereby extending the service life of the mobile phone charging line.
