Description

Technical Field

[0001] This utility model relates to a flame-retardant braided data cable, and more particularly to a flame-retardant braided data cable, belonging to the field of data cable technology. Background Technology

[0002] A data cable is used to connect mobile devices and computers to achieve data transfer or communication. In simple terms, it is a tool for connecting computers and mobile devices to transfer files such as videos, ringtones, and pictures. It can also be connected to a charger to charge mobile devices. Now, with the rapid development of the electronics industry, data cables have become an indispensable part of our lives.

[0003] Current charging data cables are generally made by wrapping a plastic film around the core wire. However, this method has technical limitations. When the data cable is used for extended periods, especially under heat, the plastic ages significantly, and the flammability is relatively high. Furthermore, existing data cables require storage after use for portability. Although some data cables can be folded to minimize their length, the connectors at both ends are still exposed. Prolonged exposure allows dust and wear to accumulate, severely impacting the cable's lifespan.

[0004] Therefore, there is an urgent need to improve flame-retardant braided data cables to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a flame-retardant braided data cable that not only has a good flame-retardant effect and prevents spontaneous combustion, but can also be folded for easy carrying. After folding, the connectors at both ends are sealed, which can effectively prevent wear or dust from entering the connectors.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a flame-retardant braided data cable, comprising a cable body and a storage shell. The cable body includes a main wire, a charging head and a USB connector respectively disposed at both ends of the main wire. The main wire includes an electric wire and a heat-resistant layer, a flame-retardant layer and a braided wear-resistant layer sequentially disposed on its surface. A storage wheel for storing the cable body is rotatably connected inside the storage shell. A handwheel for rotating the storage wheel is connected to the surface of the storage shell. A first sealing cover and a second sealing cover for sealing the USB connector and the charging head are distributed on both sides of the storage shell.

[0007] Preferably, the heat-resistant layer is a mica layer, the flame-retardant layer is a ceramicized silicone rubber layer, and the woven wear-resistant layer is a polyamide fiber woven layer.

[0008] Preferably, both sides of the storage shell are sealed by sealing cover plates, the sealing cover plates are provided with a plurality of heat dissipation holes, and the sealing cover plates are provided with through grooves for the main line to slide through.

[0009] Preferably, both the first sealing cap and the second sealing cap are connected to the storage shell by elastic ropes, and rubber pads are provided on the inner walls of the first sealing cap and the second sealing cap.

[0010] Preferably, the upper end face of the storage wheel is provided with a rotating rod that extends through to the upper end face of the storage shell, the handwheel is connected to the rotating rod, and an arc groove is formed on the side of the upper end face of the handwheel away from the rotating rod.

Detailed Implementation

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figures 1-4 As shown, the flame-retardant braided data cable provided in this embodiment includes a cable body 1 and a storage shell 2. An L-shaped clamping plate 17 is provided on the side of the storage shell 2 away from the handwheel 7. The L-shaped clamping plate 17 can fix the data cable in use to prevent shaking, and can also clamp and carry the folded data cable. The inner wall of the L-shaped clamping plate 17 is provided with a rubber anti-slip layer, which can improve the anti-slip effect when clamping and carrying, and improve the stability of carrying.

[0023] The cable body 1 includes a main cable 3, a charging head 4 and a USB connector 5 respectively disposed at both ends of the main cable 3. The main cable 3 includes an electric wire 301 and a heat-resistant layer 101, a flame-retardant layer 102 and a braided wear-resistant layer 103 disposed sequentially on its surface. The heat-resistant layer 101 is a mica layer. Mica has good high temperature resistance and electrical insulation, and is smooth, elastic and easy to process. It is an excellent fire-resistant and flame-retardant material. The heat-resistant layer made of mica is coated on the surface of the conductor to improve the flame-retardant performance of the wire.

[0024] The flame retardant layer 102 is a ceramicized silicone rubber layer. At room temperature, ceramicized silicone rubber has the softness and elasticity of ordinary silicone rubber, but after being burned by high-temperature flames, it will form a hard shell, thereby protecting the wires and cables from damage.

[0025] The braided wear-resistant layer 103 is a polyamide fiber braided layer. Polyamide fiber is a polymer material with high strength and wear resistance. It can significantly improve the tensile strength and wear resistance of the wire, making the wire less prone to damage during long-term use. At the same time, the nylon material also has waterproof, fireproof and high temperature resistance properties, which can provide comprehensive protection for the wire and further improve its flame retardancy.

[0026] When high temperatures occur inside the wire body 1, the heat-resistant layer 101 is used to initially block the temperature. The high temperature will then be blocked again by the flame-retardant layer 102 and the braided wear-resistant layer 103 to prevent the surface of the wire body 1 from overheating. When spontaneous combustion occurs inside, the flame-retardant layer 102 made of ceramicized silicone rubber will form a hard shell to block the internal flame to a certain extent, ensuring that the flame does not spread over a large area and improving the safety of use.

[0027] Both sides of the storage shell 2 are sealed by the sealing cover plate 10. The sealing cover plate 10 has several heat dissipation holes and a through groove 11 for the main line 3 to slide through.

[0028] Furthermore, a first magnet 15 is provided at the opening edge of each of the two through slots 11, and a second magnet 16 is provided on the side of the charging head 4 and the USB connector 5 near the storage shell 2, which attracts the first magnet 15. By using the mutual attraction between the first magnet 15 and the second magnet 16, it can be ensured that the charging head 4 and the USB connector 5 at both ends can be fixed after recycling, which is convenient for sealing with the first sealing cover 8 and the second sealing cover 9 later, and can effectively prevent wear and dust from entering.

[0029] The storage shell 2 is rotatably connected to a storage wheel 6 for storing the yarn 1. A handwheel 7 for rotating the storage wheel 6 is connected to the surface of the storage shell 2. A rotating rod 13 is provided on the upper end face of the storage wheel 6, which extends through to the upper end face of the storage shell 2. The handwheel 7 is connected to the rotating rod 13. An arc groove 14 is provided on the side of the upper end face of the handwheel 7 away from the rotating rod 13. When using the yarn 1, it can be pulled directly to both ends. When recycling, the storage wheel 6 is rotated by rotating the handwheel 7 to achieve synchronous recycling of both sides of the yarn 1. Since the above-mentioned rotating recycling mechanism is an existing product structure on the market, it will not be described in detail here.

[0030] The storage shell 2 has a first sealing cover 8 and a second sealing cover 9 on both sides for sealing the USB connector 5 and the charging head 4. The first sealing cover 8 and the second sealing cover 9 are both connected to the storage shell 2 by elastic ropes 12. The inner walls of the first sealing cover 8 and the second sealing cover 9 are provided with rubber pads. The rubber not only improves the sealing performance, but also improves the anti-slip performance after sealing, preventing the cover from falling off.
