Abstract
Description
Technical Field
[0001] This utility model relates to the field of USB power cable technology, and in particular to a USB auxiliary power cable harness. Background Technology
[0002] Universal Serial Bus (USB) is an emerging data communication method that is gradually replacing other interface standards. As a high-speed serial bus, the USB bus has extremely high transmission speed, which can meet the application environment requirements of high-speed data transmission. In addition, the bus also has the advantages of simple power supply (bus power supply is possible), convenient installation and configuration (supports plug and play and hot-swapping), easy expansion ports (up to 127 peripherals can be expanded through a hub), diversified transmission methods (4 transmission modes), and good compatibility (backward compatibility after product upgrades). Some power cables use USB as the plug, which are called USB auxiliary power cables.
[0003] When in use, the USB plug is exposed to the air when not inserted, which can lead to corrosion and damage. If the protective shell is adjusted on the outside, it needs to be stored after insertion. If it is fixed above the plug by a cable harness, residual dust can easily accumulate, allowing dust to enter the inside of the plug when it is protected next time. Therefore, we have proposed a USB auxiliary power cable harness. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

On one side; pull the interface protective shell 11 out from the top of the USB interface 2, so that the USB interface 2 can be inserted into the inside of other interfaces, and control the interface protective shell 11 to rotate around the rotating shaft 9 through the connecting block 10, and slide on the top of the plug body 1 through the slide rod 7, so that the through groove position of the interface protective shell 11 abuts against the top of the plug body 1, and the interface protective shell 11 and the magnetic fixing block 13 above the control handle 12 are connected to each other, so that the interface protective shell 11 can be easily stored; in this embodiment, the top of the plug body 1 is fixedly installed with the control handle 12, and the interface protective shell 11 and the control handle 12 are fixedly installed with the magnetic fixing block 13 on one side.
[0025] In this embodiment, a storage groove is provided on the top of the plug body 1, and the fixing cylinder 6 is fixedly installed on the inner wall of one side of the storage groove. The outer diameter of the connecting bracket 8 and the connecting block 10 is smaller than the inner diameter of the storage groove. In this embodiment, the protective sleeve 4 includes an insulating layer 14, a shielding layer 15, and a tensile layer 16 on its upper part. The shielding layer 15 is fixedly connected to one side of the insulating layer 14, and the tensile layer 16 is fixedly connected to one side of the shielding layer 15. The insulating layer 14, as the innermost basic protective structure, is made of high-quality polytetrafluoroethylene (PTFE). PTFE has an extremely low coefficient of friction, excellent electrical insulation performance, and resistance to high and low temperatures. It can effectively isolate current, prevent leakage, ensure the stability of current transmission inside the power harness, avoid abnormal equipment operation due to current interference, and withstand extreme temperature environments from -200℃ to 260℃, ensuring normal operation under various harsh conditions. In this embodiment, the insulating layer 14 is made of polytetrafluoroethylene. The shielding layer 15 is made of tin-plated copper wire, and the tensile layer 16 is made of aramid fiber. Shielding layer 15 is woven from tin-plated copper wire and is close to the insulation layer. Tin-plated copper wire not only has good conductivity, but the tin layer also enhances its oxidation resistance. This shielding layer can effectively block external electromagnetic interference from entering the wire harness, avoid affecting signal transmission, prevent data transmission errors or equipment failures caused by electromagnetic interference, and ensure that the USB auxiliary power cable can work stably in complex electromagnetic environments. The tensile layer 16 is made of aramid fiber. Aramid fiber has the characteristics of high strength and low density. Its strength is 5 times that of steel wire, but its weight is only one-fifth of that of steel wire. It can greatly enhance the tensile performance of the power harness, prevent the internal wires from breaking due to pulling in daily use, extend the service life of the harness, and ensure the integrity of the internal structure and maintain stable current transmission even in use scenarios with frequent bending and stretching.
[0026] In this embodiment, the upper part of the anti-bending sleeve 5 includes a buffer layer 17, a moisture-proof layer 18, and a protective layer 19. The buffer layer 17 is fixedly connected to one side of the tensile layer 16, the moisture-proof layer 18 is fixedly connected to one side of the buffer layer 17, and the protective layer 19 is fixedly connected to one side of the moisture-proof layer 18. The buffer layer 17 is made of foamed polyethylene, which has good flexibility and buffering performance, can absorb external impact, reduce damage to the inside of the wire harness caused by collision and compression, protect the insulation layer, shielding layer, and wires from physical impact damage, effectively avoid short circuits and open circuits caused by external impact, and ensure the safety of the power harness in various complex operating environments. In this embodiment, the buffer layer 17 is made of foamed polyethylene, the moisture-proof layer 18 is made of aluminum-plastic composite film, and the protective layer 19 is made of polyethylene. The power harness is made of urethane material; the moisture-proof layer 18 uses an aluminum-plastic composite film; the aluminum layer has good barrier properties, preventing moisture intrusion, while the plastic layer provides flexibility and heat-sealing properties; the aluminum-plastic composite film can effectively prevent moisture from penetrating into the harness, avoiding oxidation and rust of the wires, which would affect conductivity, and ensuring that the power harness can still work safely and reliably in humid environments such as bathrooms and kitchens; the outermost protective layer 19 is made of polyurethane material; PU material has high wear resistance, oil resistance, and chemical corrosion resistance, effectively resisting friction and wear in daily use, preventing external sharp objects from scratching or damaging the harness, protecting the internal structure from damage, extending the service life of the power harness, and ensuring that the harness maintains good performance even during frequent plugging and unplugging and friction with other objects.
[0027] The implementation principle of a USB auxiliary power cable harness in this embodiment is as follows: The interface protective shell 11 is pulled out from above the USB interface 2, allowing the USB interface 2 to be inserted into another interface. The interface protective shell 11 is controlled to rotate around the rotating shaft 9 via the connecting block 10, and slides above the plug body 1 via the slide rod 7. This allows the through slot of the interface protective shell 11 to abut against the top of the plug body 1, and connects the interface protective shell 11 to the magnetic fixing block 13 above the control handle 12. This facilitates the storage of the interface protective shell 11, and during storage... During the process, dust is not easily allowed to enter the inside. The control handle 12 allows the operator to assist in plugging and unplugging the plug body 1 and USB interface 2, making it easy for the operator to operate the plug body 1 and USB interface 2. The protective sleeve 4 and the anti-bending sleeve 5 have high wear resistance, oil resistance and chemical corrosion resistance, which can effectively resist friction and wear in daily use, prevent external sharp objects from scratching and damaging the wire harness, protect the internal structure from damage, extend the service life of the power wire harness, and enable the wire harness to maintain good performance even in the process of frequent plugging and unplugging and friction with other objects.
