DETAILED DESCRIPTION

[0018] The technical scheme in the utility model embodiment will be described clearly and completely in conjunction with the drawings of the utility model embodiment, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the scope of the utility model protection.

[0019] Embodiment one

[0020] In conjunction with Figures 1-3 , a kind of USB wire harness with signal amplifier, including main plug 1 by connecting line installation in the rear end of branch card 2, the front end of branch card 2 is connected with ground wire 3, data line segment 4, USB transmission line 5, the front end of USB transmission line 5 is connected with USB line segment 6, and the front end of USB line segment 6 is connected with extension line 8 by signal amplifier body 7.

[0021] Refer toFigure 2 Furthermore, the extension cable 8 is connected to a USB transmission plug 9 at its front end, and the outer ring of the USB cable segment 6 is fitted with suction cup fixing sleeves 10 at both the front and rear ends. The top of the suction cup fixing sleeve 10 is fixedly connected with an elastic buckle 11 that is compatible with the extension cable 8. The outer rings of the data cable segment 4, USB transmission cable 5, extension cable 8, and grounding wire 3 are all equipped with number tubes. The combined length of the USB cable segment 6, extension cable 8, and USB transmission cable 5 is 3.5 meters. The suction cup fixing sleeve 10 and the USB cable segment 6 are slidably connected, and the suction cup fixing sleeve 10 is made of rigid material.

[0022] Specifically, by adding a signal amplifier body 7 at the connection between the extension cable 8 and the USB cable segment 6, the transmission rate will not be significantly affected after the extension. At the same time, when the front row or when the extension cable 8 is not needed to be long, the extension cable 8 can be folded and the folded extension cable 8 can be locked in the elastic buckle 11 to fix the two ends of the folded extension cable 8, preventing the extension cable 8 from easily unraveling and improving the use effect. At the same time, by attaching the suction cup fixing sleeve 10 to glass or other smooth surfaces, the extension cable 8 can be fixed and prevented from falling to the bottom after being released.

[0023] Example 2

[0024] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, a strap 12 is installed in the center of the outer ring of the USB cable segment 6 via a sliding sleeve. A hook and loop fastener 13 is provided at the top of the strap 12 and at the end away from the USB cable segment 6. A hook and loop fastener fleece surface is provided on the bottom surface of the strap 12 to adapt to and match the hook and loop fastener fastener 13.

[0025] Specifically, after the extension cable 8 is fixed, the cable tie 12 can be wrapped around the USB cable segment 6 and the extension cable 8 to fix the middle of the extension cable 8. At the same time, after the grounding wire 3, data cable segment 4, USB cable segment 6 and extension cable 8 are rolled up, the cable tie 12 can also be wrapped around each end of the rolled-up wires to store and fix them, preventing them from unraveling. Moreover, the fixing process does not require the use of other cable ties or other parts, making it highly flexible in use.

[0026] In actual operation, by adding a signal amplifier body 7 at the connection between the extension cable 8 and the USB cable segment 6, the transmission rate will not be significantly affected after the extension. At the same time, when the front row or when the extension cable 8 is not required to be long;

[0027] The extension line 8 can be folded, and the folded extension line 8 is clamped in the elastic buckle 11 to fix the two ends of the folded extension line 8, so that the extension line 8 cannot be easily scattered, the use effect is improved, and the extension line 8 can be fixed in a mode of being sucked on glass or other smooth surfaces by the sucker fixing sleeve 10, so that the extension line 8 cannot fall to the lowermost position after being dropped by hand;

[0028] After the extension line 8 is fixed, the binding belt 12 can be wound on the USB line segment 6 and the extension line 8 to fix the middle part of the extension line 8, and after the ground wire 3, the data line segment 4, the USB line segment 6 and the extension line 8 are wound, the binding belt 12 can also be wound on the wire ends after winding to be stored and fixed, so that the wire ends cannot be scattered, and the fixing process does not need to use other binding belts and the like, and the use flexibility is higher.

[0029] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
