DETAILED DESCRIPTION

[0017] The following is only a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions under the concept of the present invention should fall within the scope of protection of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figures 1 to 6 As shown, a plug-in type tailgate lamp wiring harness includes a wiring harness body 1. The wiring harness body 1 is a wiring harness composed of several single wires, both ends of which are connected to terminal blocks 15 for easy connection to the connection port between the vehicle body and the lamp.

[0019] The wiring harness body 1 is also provided with a plug-in type rear cover 2, which is used to be fixed at the opening of the lamp housing 18 to seal the opening of the lamp housing 18. The plug-in type rear cover 2 includes a rear cover body 3 and a rear cover end cover 4. A number of wire holes 5 are provided on the rear cover body 3 and the rear cover end cover 4 for the wiring harness body 1 to pass through. In order to seal the wire holes 5 on the rear cover body 3 and the rear cover end cover 4, a sealing cavity 6 is provided on the front side of the rear cover body 3. The wire holes 5 are located in the sealing cavity 6. A sealing plug 7 is provided in the sealing cavity 6, and the sealing plug 7 is filled in the sealing cavity 6. In order to ensure that the wiring harness body 1 can pass through normally, a wire hole 5 is also provided on the sealing plug 7. Since the sealing plug 7 is made of a soft material, such as silicone, the diameter of the wire hole 5 provided thereon can be slightly smaller than the diameter of the wiring harness body 1, so that the sealing plug 7 fits tightly with the wiring harness body 1. The rear cover end cap 4 covers one side of the sealing cavity 6 and fixes the sealing plug 7 in the sealing cavity 6 so that the sealing plug 7 can seal the wire hole 5 .

[0020] The rear cover end cap 4 covers the opening of the sealed cavity 6, and the rear cover end cap 4 is fixedly connected to the rear cover main body 3. Two first snaps 8 are provided on the front side of the rear cover main body, and two first snap holes 9 are provided on the rear cover end cap 4. When the rear cover end cap 4 is covered on the rear cover main body 3, the two first snaps 8 will be respectively inserted into the two first snap holes 9, so that the rear cover end cap 4 is fixed to the rear cover main body 3. Two first positioning blocks 10 are also provided on the front side of the rear cover main body 3, and two first positioning grooves are provided on the rear cover end cap 4. The first positioning blocks 10 slide in conjunction with the first positioning grooves, so that the relative position between the rear cover end cap 4 and the rear cover main body 3 is fixed. The rear cover end cap 4 can only be connected and fixed to the rear cover main body 3 in a fixed direction to ensure that the first snaps 8 and the first snap holes 9 can be connected.

[0021] Two buckle blocks 11 are fixed to the rear side of the rear cover body 3. Buckle slots 16 are provided on the external lamp housing 18. When the rear side of the rear cover body 3 is inserted into the lamp housing 18, the two buckle blocks 11 snap into the buckle slots 16, securing the rear cover body 3 to the lamp housing 18. In this design, after the rear side of the rear cover body 3 is inserted into the lamp housing 18, the rear cover body 3 is rotated, causing the two buckle blocks 11 on the rear side of the rear cover body 3 to move from one side of the buckle slot 16 into the buckle slot 16. To ensure smooth movement of the buckle blocks 11 into the buckle slot 16, the buckle blocks 11 are provided with an inclined surface on the front side in the direction of rotation. Therefore, in order to prevent the buckle block 11 from rotating out of the buckle groove 16, two second positioning blocks 12 are provided on the rear side of the rear cover body 3, and two fixing blocks 17 are also provided on the inner side of the lamp housing 18. The rear cover body 3 is rotated until the second positioning block 12 is against one side of the fixing block 17, and the buckle block 11 is just buckled into the buckle groove 16. At this time, the rear cover body 3 cannot continue to rotate in this direction.

[0022] The rear cover body 3 is also provided with a sealing ring 13. A raised circular plate 14 is fixedly mounted in the middle of the rear cover body 3. The circular plate 14 has a larger diameter than the rear cover body 3. The sealing ring 13 is located between the circular plate 14 and the buckle 11. When the rear cover body 3 is fixed to the lamp housing 18, the circular plate 14 and the outer wall of the lamp housing 18 squeeze the sealing ring 13, causing it to firmly adhere to the circular plate 14 and the surface of the lamp housing 18, thereby sealing the opening in the lamp housing 18.

[0023] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
