Description

Technical Field

[0001] This utility model relates to the field of data cable technology, specifically a wear-resistant data cable. Background Technology

[0002] A data cable is an essential component for connecting a hard drive to the motherboard, and it is usually included when you purchase a motherboard. Each data cable can only connect two IDE devices. With the widespread use of electronic devices, data cables have become an indispensable accessory.

[0003] Existing data cables frequently rub against various surfaces during daily use, such as when placed in a bag and rubbing against other items, or when the connector rubs against the interface during frequent plugging and unplugging. This causes the outer sheath of the data cable to wear down easily. Once the outer sheath is worn, the internal wires are easily exposed, which not only affects the lifespan of the data cable but may also cause safety hazards such as short circuits and electrical leakage. Moreover, some data cables on the market currently have poor wear resistance at the connector, which can easily become loose and have poor contact after repeated plugging and unplugging, affecting data transmission and charging performance. Therefore, a data cable with good wear resistance is needed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a wear-resistant data cable with strong wear resistance, strong connector durability and multiple protective functions.

[0005] To solve the above problems, the technical solution of this utility model is as follows: a wear-resistant data cable, including a data cable body, the data cable body including an inner conductor and an outer sheath wrapped around the conductor, the outer sheath adopts a multi-layer composite structure, from the inside to the outside being an insulation layer, a buffer layer and a wear-resistant outer layer; the insulation layer is made of polyvinyl chloride material, the buffer layer is made of rubber material, and the wear-resistant outer layer is made of polyurethane material.

[0006] Furthermore, the data cable body has connectors at both ends. Each connector includes a metal terminal and a connector shell that wraps around the metal terminal. The connector shell is made of metal and has a frosted surface. The connection between the metal terminal and the wire is made by welding, and a layer of waterproof adhesive is applied to the weld.

[0007] Furthermore, the metal material of the connector housing is stainless steel.

[0008] Furthermore, a metal woven protective mesh is provided between the insulation layer and the buffer layer, and the metal woven protective mesh is tightly attached to the insulation layer.

[0009] Furthermore, the metal braided protective mesh can effectively disperse external forces, enhance the wear resistance of the data cable, and shield external electromagnetic interference.

[0010] Furthermore, the buffer layer has good elasticity, which can buffer external impact forces and reduce damage to the conductor.

[0011] Furthermore, the insulating layer can effectively isolate the current in the conductor and prevent leakage.

[0012] Furthermore, the connector transmits data and supplies power to external devices via metal terminals.

[0013] The advantages of this invention compared to existing technologies are as follows:

[0014] (1) The outer sheath of this utility model adopts a multi-layer composite structure. In particular, the wear-resistant outer layer uses polyurethane material, which greatly improves the overall wear resistance of the data cable and reduces the damage to the outer sheath caused by daily friction.

[0015] (2) The durability of the connector is enhanced. The connector shell is made of metal and has been sanded. The special treatment of the metal terminal connection part makes the connector more wear-resistant, reduces the occurrence of problems such as poor contact, and extends the service life of the connector.

[0016] (3) The metal braided protective mesh in this utility model not only enhances wear resistance but also shields electromagnetic interference. At the same time, the buffer layer can effectively protect the wires from external impacts, improving the stability and reliability of the data cable. Attached Figure Description

[0024] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, a wear-resistant data cable includes a data cable body 1, which comprises an inner conductor 2 and an outer sheath 3 wrapped around the conductor 2. The outer sheath 3 adopts a multi-layer composite structure, consisting of an insulation layer 301, a buffer layer 302, and a wear-resistant outer layer 303 from the inside out. The insulation layer 301 is made of polyvinyl chloride (PVC), the buffer layer 302 is made of rubber, and the wear-resistant outer layer 303 is made of polyurethane. Polyurethane can resist daily friction. The buffer layer 302 has good elasticity, which can buffer external impact and reduce damage to the conductor. The insulation layer 301 can effectively isolate the current in the conductor and prevent leakage. The multi-layer composite structure of the outer sheath 3, especially the use of polyurethane in the wear-resistant outer layer 303, greatly improves the overall wear resistance of the data cable and reduces damage to the outer sheath caused by daily friction.

[0026] The data cable body 1 has connectors 4 at both ends. Each connector 4 includes a metal terminal 401 and a connector housing 402 enclosing the metal terminal 401. The connector housing 402 is made of metal and has a frosted surface. The connection between the metal terminal 401 and the wire 2 is achieved by welding, and a layer of waterproof adhesive 5 is applied to the weld. The metal material of the connector housing 402 is stainless steel. The connector 4 transmits data and supplies power to external devices through the metal terminal 401. The frosted metal material of the connector housing 402 and the special treatment of the connection part of the metal terminal 401 make the connector 4 more wear-resistant, reduce the occurrence of problems such as poor contact, and extend the service life of the connector.

[0027] A metal braided protective mesh 6 is provided between the insulation layer 301 and the buffer layer 302. The metal braided protective mesh 6 is tightly attached to the insulation layer 301. The metal braided protective mesh 6 can effectively disperse external forces, enhance the wear resistance of the data cable, and shield external electromagnetic interference. The metal braided protective mesh 6 not only enhances wear resistance but also shields electromagnetic interference. At the same time, the buffer layer can effectively protect the conductor 2 from external impacts, improving the stability and reliability of the data cable.

[0028] In practical use, the insulation layer 301 is first fabricated by extruding polyvinyl chloride (PVC) material around the conductor to form a uniform insulation layer 301. Then, a metal braided protective mesh 6 is woven around the insulation layer 301 to ensure a tight fit. Next, rubber material is injection molded onto the metal braided protective mesh to form a buffer layer 302. Finally, polyurethane material is extruded around the buffer layer to form a wear-resistant outer layer 303, completing the fabrication of the data cable sheath 3. The ends of the conductor 2 are then soldered to the metal terminals 401 to ensure a secure connection. Waterproof adhesive 5 is applied to the solder joints. After the adhesive 5 dries, the metal terminals 401 are inserted into the frosted stainless steel connector housing 402 to complete the assembly of the connector 4. The assembled connector 4 is then connected to the fabricated data cable body 1, ensuring a tight connection, thus completing the fabrication of the wear-resistant data cable.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
