Description

Technical Field

[0001] This utility model relates to the field of data cable technology, and in particular to a high-strength flame-retardant braided data cable. Background Technology

[0002] With the development of the electronics industry, mobile devices have become indispensable tools in people's lives. Data cables, in turn, have become an essential part of daily life because they provide necessary battery life for mobile devices. Data cables can be used to charge mobile devices and connect them to external electronic devices. A utility model patent application with application number 202222492769.2, entitled "Anti-Sway Braided Data Cable," discloses an anti-sway braided data cable, including a cable body comprising multiple lines interwoven together. Each line contains multiple wire cores, which are also interwoven. Each wire core comprises multiple metal wires interwoven together. The wire cores are formed by the interweaving of multiple metal wires, which in turn form lines, and finally, the lines interweave to form the cable body. While this data cable improves the cable's flexibility and anti-sway properties through its braided structure, thus enhancing the user experience, it lacks flame-retardant properties and fails to address the fire resistance issue of the data cable. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength, flame-retardant braided data cable.

[0004] According to one aspect of the present invention, a high-strength flame-retardant braided data cable is provided, comprising:

[0005] Inner core wire;

[0006] A shielding layer that wraps around the inner core wire and provides shielding.

[0007] A braided shielding layer disposed on the outer surface of the shielding layer and wrapped around the shielding layer;

[0008] A flame-retardant outer layer is placed on the outer surface of the braided shielding layer and wraps around the braided shielding layer;

[0009] It is placed on the outer surface of the flame-retardant outer layer and wraps the flame-retardant yarn woven layer of the flame-retardant outer layer.

[0010] In some implementations, the inner core wire includes a core wire assembly, which includes two signal transmission wires, two signal control and detection wires, and three power wires.

[0011] In some implementations, two signal transmission wires are located between two adjacent power lines, and two signal control and monitoring wires are inserted between three power lines at intervals, with power lines on both sides of each signal control and monitoring wire.

[0012] In some embodiments, the inner core wire also includes a filler wire, two signal transmission wires, two signal control and monitoring wires, and three power wires that are hinged together to form a core wire assembly and surround the outside of the filler wire.

[0013] In some implementations, the filler filaments are four nylon filaments.

[0014] In some embodiments, the flame-retardant outer layer is a high-strength flame-retardant outer layer made of polymeric material, which contains a foam flame retardant.

[0015] In some embodiments, the flame-retardant yarn braided layer is a PET flame-retardant yarn braided layer.

[0016] In some implementations, the shielding layer is an aluminum foil shielding layer.

[0017] In some implementations, the braided shielding layer is a metal braided shielding layer, which is made of several shielding metal wires woven together.

[0018] The beneficial effects of this invention are as follows: This invention achieves dual shielding against external interference by setting a shielding layer and a braided shielding layer on the outside of the inner core wire, thus improving the anti-interference performance of the data cable; by setting a flame-retardant outer sheath layer with high strength and flame-retardant effect and a flame-retardant braided layer, it provides dual fire-retardant protection for the data cable, greatly improving its safety; by filling the center of the inner core wire with nylon filaments, it improves the toughness and swing life of the data cable. This invention improves fire resistance and enhances the user experience while ensuring the cable's plasticity and anti-swing properties. Attached Figure Description

[0019] Figure 1 This is a cross-sectional view of a high-strength flame-retardant braided data cable according to one embodiment of the present invention. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the embodiments.

[0021] refer to Figure 1 This utility model provides a high-strength flame-retardant braided data cable, including an inner core wire 1; a shielding layer 2 that wraps around the inner core wire 1 and provides shielding; a braided shielding layer 3 that is disposed on the outer surface of the shielding layer 2 and wraps around the shielding layer 2; a flame-retardant outer sheath 4 that is disposed on the outer surface of the braided shielding layer 3 and wraps around the braided shielding layer 3; and a flame-retardant yarn braided layer 5 that is disposed on the outer surface of the flame-retardant outer sheath 4 and wraps around the flame-retardant outer sheath 4.

[0022] The inner core wire 1 includes a core wire assembly and four filler wires 14. The core wire assembly includes two signal transmission wires 11, two signal control and detection wires 12, and three power wires 13. The two signal transmission wires 11 are located between two adjacent power wires 13, and the two signal control and detection wires 12 are inserted between the three power wires 13 at intervals. Each signal control and detection wire 12 has a power wire 13 on both sides. The two signal transmission wires 11, the two signal control and detection wires 12, and the three power wires 13 are hinged together to form the core wire assembly and surround the four filler wires 14. The filler wires 14 are made of nylon and provide toughness to the data cable, increasing its swing life.

[0023] The flame-retardant outer sheath 4 is a high-strength flame-retardant polymer material that provides protection for the inner core wire 1, the shielding layer, and the braided shielding layer 3, enhancing the fire resistance and flame-retardant performance of the data cable. The high-strength flame-retardant outer sheath 4 utilizes foam flame-retardant technology, incorporating foam flame retardants into the polymer material. When the temperature of the high-strength flame-retardant polymer material reaches above 400℃, the foam flame retardant takes effect, rapidly generating flame-retardant foam to cover the product surface, isolating it from the air and thus quickly extinguishing the flame.

[0024] The flame-retardant braided layer 5 is a PET flame-retardant braided layer, enhancing the aesthetics of the data cable. It also forms a double-layer protection with the flame-retardant outer sheath layer 4, providing protection for the inner core wire 1, shielding layer 2, and braided shielding layer 3. Shielding layer 2 is an aluminum foil shielding layer. Braided shielding layer 3 is a metal braided shielding layer, composed of several shielding metal wires woven together. The aluminum foil shielding layer and the metal braided shielding layer provide double shielding for the data cable, enhancing its resistance to external interference.

[0025] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
