Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figure 1 and Figure 2 This utility model provides a structure to prevent the detachment of a vehicle light wire. The structure includes a fixing seat, a rubber seat 101, and a wire harness anti-detachment ring 102. The fixing seat is installed at the connection sheet metal hole 104 of the vehicle light housing 103. The rubber seat 101 is provided on the outer side of the fixing seat of the vehicle light housing 103. The wire harness anti-detachment ring 102 is installed on the end of the rubber seat 101 away from the fixing seat through an adhesive layer 105. The vehicle light wire 106 is welded inside the wire harness anti-detachment ring 102 using ultrasonic and high-frequency welding technology. The vehicle light wire 106 passes through the rubber seat 101 and the fixing seat in sequence.

[0018] The mounting base includes a base body 107, an insert rod 108, and a fixing nut 109. The insert rod 108 is fixedly disposed on the side of the base body 107 facing the headlight housing 103. The insert rod 108 is inserted into the connecting sheet metal hole 104. The end of the insert rod 108 away from the base body 107 extends to the outside of the connecting sheet metal hole 104. A threaded portion 110 is provided on the outside of the end of the insert rod 108 away from the base body 107. The fixing nut 109 is adapted to the threaded portion 110. The rubber seat 101 is disposed on the end of the base body 107 away from the insert rod 108.

[0019] In this embodiment, the seat 107 is attached to the outer wall of the headlight housing 103, so that the insert rod 108 is inserted into the connecting sheet metal hole 104. The fixing nut 109 is tightened at the threaded portion 110, thereby completing the installation of the fixing seat. The rubber seat 101 is installed at the end of the fixing seat away from the headlight housing 103. The headlight wire 106 is welded to the inside of the wire harness thrust ring using ultrasonic and high-frequency welding technology. The wire harness thrust ring is fixed to the rubber seat 101 by the adhesive layer 105. The headlight wire 106 passes through the rubber seat 101, the seat 107 and the insert rod 108 in sequence and is electrically connected to the headlight, thereby completing the installation of the headlight wire 106. The above structure greatly enhances the stability of the headlight wire 106 installation and effectively prevents the headlight wire 106 from falling off.

[0020] Furthermore, the end of the seat 107 away from the embedded rod 108 is provided with a mounting groove 111, and the inner sidewall of the mounting groove 111 is provided with an embedding groove 112. The outer sidewall of the end of the rubber seat 101 away from the wire harness anti-reverse ring 102 is provided with an embedding protrusion 113. The embedding protrusion 113 is interference-fitted with the embedding groove 112. The end face of the inner sidewall of the mounting groove 111 is also provided with a barb-shaped protrusion 116. The outer sidewall of the rubber seat 101 is also provided with a limiting protrusion 117, which is adapted to the barb-shaped protrusion 116.

[0021] In this embodiment, the connection between the rubber seat 101 and the fixed seat is completed by the installation groove 111, the embedding groove 112 and the embedding protrusion 113, and the structure of the rubber seat 101 installed in the installation groove 111 is more secure by the barbed protrusion 116 and the limiting protrusion 117.

[0023] In this embodiment, the welding protrusion 114 increases the contact area and welding area between the headlight wire 106 and the wiring harness anti-reverse ring 102, making the ultrasonic and high-frequency welding more robust and improving the connection strength between the headlight wire 106 and the wiring harness anti-reverse ring 102. This effectively prevents the headlight wire 106 from coming out of the wiring harness anti-reverse ring 102 when under stress. At the same time, the welding protrusion 114 can disperse the tensile force on the headlight wire 106 to a certain extent, so that the tensile force is applied more evenly to the welding part between the headlight wire 106 and the wiring harness anti-reverse ring 102, reducing local stress concentration and extending the service life of the headlight wire 106 and the welding part.

[0024] Furthermore, a washer 115 is provided on the side of the fixing nut 109 facing the headlight housing 103, and the washer 115 is provided on the outside of the embedded rod 108.

[0025] In this embodiment, the wear of the fixing nut 109 is reduced and the service life of the fixing nut 109 is improved by setting the gasket 115.

[0026] Furthermore, the outer shell of the headlight wire 106 and the wire harness anti-reverse coil 102 are both made of PVC material.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
