[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to block water and dust, as an embodiment of the present invention, Figure 1 、 Figure 2 As shown, the utility model relates to a waterproof and dustproof automotive electronic wiring harness, comprising a wiring harness body 1, with plug-in terminals 2 provided at both ends of the wiring harness body 1, the two plug-in terminals 2 being crimped and connected to the wiring harness body 1, protective sleeves 3 being fixed to the two plug-in terminals 2 by adhesive, a support member 5 being provided between the two protective sleeves 3, protective covers 4 being provided at the ends of the two protective sleeves 3 away from the plug-in terminals 2, sealing gaskets 9 being fixed to the opposite ends of the two protective covers 4 by adhesive, slide grooves being provided on both sides of the two protective covers 4, an insert block 10 being provided in each slide groove, two slots being provided on the two protective sleeves 3 being adapted for the insert block 10, a boss 12 being integrally formed on the side wall of each insert block 10 close to the plug-in terminal 2, a spring 13 being sleeved on each boss 12, a pressure block 11 being fixed to the side wall of each insert block 10 away from the plug-in terminal 2 by adhesive, and through grooves being adapted for the pressure block 11 being provided on both sides of the two protective covers 4.

[0024] When the plug-in terminal 2 is not in use, press the pressure block 11 on the protective cover 4, cover the protective cover 4 on the protective sleeve 3, and then release the pressure block 11. The spring 13 pushes the plug block 10 to move away from the plug-in terminal 2, and the plug block 10 is inserted into the slot on the protective sleeve 3 to facilitate the connection between the protective sleeve 3 and the protective cover 4. The protective sleeve 3, the protective cover 4, and the sealing gasket 9 cooperate to block external dust and water, preventing the plug-in terminal 2 from being invaded by dust and water. When the plug-in terminal 2 needs to be used, press the pressure block 11, and the plug block 10 moves toward the plug-in terminal 2, making it convenient to remove the protective cover 4.

[0025] In order to facilitate pressing the pressing block 11, for example, Figure 2 As shown, each of the pressing blocks 11 has a plurality of anti-slip protrusions integrally formed on the side wall away from the plug-in terminal 2 .

[0026] In order to facilitate the combing of the harness body 1, for example, Figure 1 、 Figure 3 As shown, the support member 5 includes a block 6, a support 7 and a connecting bolt 60. The side walls of the block 6 and the support 7 facing each other are provided with a slot adapted to the wiring harness body 1. There are two connecting bolts 60. Two screw holes adapted to the connecting bolts 60 are provided on the block 6 and the support 7, and mounting holes are provided on both sides of the support 7.

[0027] When in use, loosen the two connecting bolts 60 to release the clamping of the wiring harness body 1, and slide the block 6 and the support 7 to adjust the distance between the support 7 and one of the plug-in terminals 2 according to installation needs. Tighten the two connecting bolts 60, and pass the end of the bolt used to fix the support 7 through the mounting hole on the support 7, so as to fix the support 7 in a suitable position and facilitate the combing of the wiring harness body 1.

[0028] In order to prevent the block 6 and the support 7 from pinching the wiring harness body 1, for example, Figure 3 As shown, a protective pad 61 is provided in each of the card slots.

[0029] In order to prevent the protective cover 4 from being lost after being removed, for example, Figure 1 As shown, a connecting rope 8 is fixed to both protective sleeves 3 via adhesive, one of the connecting ropes 8 is connected to one of the protective covers 4 via adhesive, and the other connecting rope 8 is connected to the other protective cover 4 via adhesive.

[0030] When the utility model is in use, the pressing block 11 on the protective cover 4 is pressed, the protective cover 4 is covered on the protective sleeve 3, and then the pressing block 11 is released. The spring 13 pushes the plug block 10 to move away from the plug terminal 2, and the plug block 10 is inserted into the slot on the protective sleeve 3, which facilitates the connection between the protective sleeve 3 and the protective cover 4. The protective sleeve 3, the protective cover 4, and the sealing gasket 9 cooperate to block external dust and water, preventing the plug terminal 2 from being invaded by dust and water;

[0031] When the plug terminal 2 is needed, the pressing block 11 is pressed, and the plug block 10 moves toward the plug terminal 2, making it easy to remove the protective cover 4. The connecting rope 8 can prevent the protective cover 4 from being lost after removal.

[0032] By loosening the two connecting bolts 60, the clamping of the wiring harness body 1 can be released. The sliding block 6 and the support 7 can adjust the distance between the support 7 and one of the plug-in terminals 2 according to installation needs. Tighten the two connecting bolts 60 and pass the end of the bolt used to fix the support 7 through the mounting hole on the support 7 to facilitate fixing the support 7 in a suitable position and combing the wiring harness body 1.
