[0002] The automotive wiring harness is one of the important components of the automotive system. In the process of connecting various parts, the automotive wiring harness often needs to pass through the sheet metal hole of the car. In order to facilitate the passage of the automotive wiring harness, the inner diameter of the sheet metal hole is usually larger than the outer diameter of the automotive wiring harness. After the automotive wiring harness is inserted into the sheet metal hole for connection, there is a certain gap between the automotive wiring harness and the sheet metal hole. In order to prevent dust, rainwater, etc. from entering from these gaps, it is necessary to put a protective cover on the automotive wiring harness to block the gap between the sheet metal hole and the automotive wiring harness and seal it through the wiring harness protective cover; the existing wiring harness includes a cover that is often a rubber part directly clamped on the automotive outlet hole. When there are fewer wiring harnesses, the wiring harness moves in the wiring harness protective cover, which fails to fix the wiring harness and prevent dust. In addition, the wiring harness moves back and forth, causing friction damage to the outer surface of the wiring harness, reducing the service life of the wiring harness. Utility Model Content

A wiring tube is sleeved in the through hole, a retaining ring is provided at the lower end of the wiring tube, and a groove matching the retaining ring is provided at the bottom end of the fixed part, a plurality of evenly arranged clamping protrusions are provided on the upper end side wall of the wiring tube, a wire pressing part is provided inside the upper end of the wiring tube, an adjusting cap is provided above the wire pressing part, a wire outlet hole is provided at the top of the adjusting cap, and an extrusion part for extruding the wire pressing part is provided inside the adjusting cap, the lower end of the adjusting cap is detachably fixedly connected to the upper end of the fixed part, the adjusting cap is rotated, the adjusting cap moves downward, and the extrusion part of the adjusting cap presses the wire harness toward the middle against the wire pressing part, so as to achieve the purpose of fixing the wire harness. A tubular connecting part is provided at the upper end of the fixed part, an external thread is provided on the outer wall of the connecting part, an internal thread matching the connecting part is provided inside the lower end of the adjusting cap, and the adjusting cap is threadedly connected to the connecting part.

[0004] Preferably, an anti-slip protrusion for increasing friction is provided on the outer wall of the adjusting cap.

[0005] Preferably, the cross section of the clamping groove is trapezoidal, so as to facilitate clamping and fixing the fixing part at the wire outlet hole of the automobile.

[0006] Preferably, the first clamping block and the second clamping block are both in a truncated cone shape, which is convenient for passing through the wiring hole of the automobile.

[0007] Preferably, the diameter of the wire outlet hole is smaller than the inner diameter of the wire routing tube.

[0008] The above solution has the following advantages:

[0009] The wiring tube can be detachably connected to the fixed part by a retaining ring and a clamping protrusion, which is convenient for disassembling and replacing wiring tubes with different inner diameters according to needs; the adjustment cap is set, the adjustment cap is turned, the adjustment cap moves downward, and the extrusion part of the adjustment cap presses the wire pressing part to squeeze the wire harness toward the middle, thereby fixing the wire harness and achieving the purpose of dust prevention; the adjustment cap is threadedly connected to the fixed part, which is convenient for disassembling and replacing the wiring tube.
