Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a device for preventing the pull-out of vehicle headlight wiring harness. Background Technology

[0002] In the automotive manufacturing industry, the connection stability of headlight wiring harnesses is crucial for the normal operation of headlights. With existing headlight wiring harness connection methods, during vehicle operation, external factors such as bumps and vibrations can easily cause the wiring harnesses to loosen or even detach. This not only prevents the headlights from illuminating properly, affecting driving safety, but may also trigger electrical faults, adversely impacting the overall performance and reliability of the vehicle.

[0003] Currently, although there are some wiring harness fixing devices for fixing vehicle headlight wiring harnesses, most of them have complex structures, are inconvenient to install, and are not ideal in preventing the wiring harnesses from being pulled off, thus failing to effectively solve the problem of vehicle headlight wiring harnesses easily falling off. Utility Model Content

[0004] The purpose of this utility model is to provide a device to prevent vehicle light wiring harness from coming loose, thereby solving the problem of existing vehicle light wiring harnesses being prone to detachment.

[0005] To achieve the above objectives, this utility model provides a vehicle headlight wiring harness anti-pull-out device. The device includes a rubber seat and a wiring harness anti-pull-out ring. The rubber seat is mounted on the headlight housing and positioned outside the wiring harness connection sheet metal hole in the headlight housing. A through hole is provided on the rubber seat, corresponding to the wiring harness connection sheet metal hole. The wiring harness anti-pull-out ring is mounted on the end of the rubber seat away from the headlight housing via a fixing layer. The headlight wiring harness is welded inside the wiring harness anti-pull-out ring using ultrasonic and high-frequency welding techniques. The headlight wiring harness passes sequentially through the through hole and the wiring harness connection sheet metal hole.

[0006] The wiring harness anti-reverse ring has a welding protrusion on the side away from the rubber seat, and part of the vehicle lamp wiring harness is welded inside the welding protrusion.

[0007] The diameters of the through hole and the wiring harness connecting sheet metal hole are both larger than the diameter of the vehicle headlight wiring harness.

[0008] The outer shell of the vehicle light wiring harness and the anti-reverse ring of the wiring harness are both made of PVC material.

[0009] This utility model discloses an anti-pull-out device for vehicle lamp wiring harnesses, comprising a rubber seat and a wiring harness anti-pull-out ring. The rubber seat is mounted on the vehicle lamp housing and disposed outside the wiring harness connection sheet metal hole of the vehicle lamp housing. A through hole is provided on the rubber seat, corresponding to the wiring harness connection sheet metal hole. The rubber seat is mounted outside the wiring harness connection sheet metal hole, and its through hole corresponds to the wiring harness connection sheet metal hole, providing a stable channel for the vehicle lamp wiring harness. At the same time, the wiring harness anti-pull-out ring is mounted on the rubber seat away from the vehicle lamp housing through the fixing layer. One end of the lamp housing serves to limit the movement of the lamp wiring harness. More importantly, the wiring harness anti-reverse ring is welded to the lamp wiring harness using ultrasonic and high-frequency welding technology. This welding method ensures a firm connection between the lamp wiring harness and the anti-reverse ring. When the lamp wiring harness is subjected to tension, the anti-reverse ring effectively prevents the lamp wiring harness from being pulled out. At the same time, the rubber seat also provides auxiliary fixation and cushioning. Together, these two elements greatly enhance the stability of the lamp wiring harness connection, thereby effectively solving the problem of existing wiring harnesses being prone to detachment.

[0013] The embodiments of this utility model are described in detail below. 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.

[0014] Please see Figure 1This utility model provides a vehicle headlight wiring harness 107 anti-pull-out device, which includes a rubber seat 101 and a wiring harness anti-pull-out ring 102. The rubber seat 101 is installed on the headlight housing 103 and is located outside the wiring harness connection sheet metal hole 104 of the headlight housing 103. A through hole 105 is provided on the rubber seat 101, which corresponds to the wiring harness connection sheet metal hole 104. The wiring harness anti-pull-out ring 102 is installed on the end of the rubber seat 101 away from the headlight housing 103 through a fixing layer 106. The headlight wiring harness 107 is welded inside the wiring harness anti-pull-out ring 102 by ultrasonic and high-frequency welding technology. The headlight wiring harness 107 passes through the through hole 105 and the wiring harness connection sheet metal hole 104 in sequence.

[0015] In this embodiment, the rubber seat 101 is installed outside the wiring harness connection sheet metal hole 104, and its through hole 105 corresponds to the wiring harness connection sheet metal hole 104, providing a stable channel for the headlight wiring harness 107. At the same time, the wiring harness anti-reverse ring 102 is installed on the end of the rubber seat 101 away from the headlight housing 103 through the fixing layer 106, which limits the headlight wiring harness 107. More importantly, the headlight wiring harness 107 is welded inside the wiring harness anti-reverse ring 102 using ultrasonic and high-frequency welding technology. This welding method makes the headlight wiring harness 107 firmly connected to the wiring harness anti-reverse ring 102. When the headlight wiring harness 107 is subjected to tension, the wiring harness anti-reverse ring 102 can effectively prevent the headlight wiring harness 107 from being pulled out. At the same time, the rubber seat 101 also plays an auxiliary fixing and buffering role. The two work together to greatly enhance the stability of the headlight wiring harness 107 connection, thereby effectively solving the problem of existing wiring harnesses being easy to fall off.

[0016] Furthermore, the side of the wiring harness anti-reverse ring 102 away from the rubber seat 101 is provided with a welding protrusion 108, and part of the vehicle lamp wiring harness 107 is welded inside the welding protrusion 108.

[0017] In this embodiment, the welding protrusion 108 increases the contact area and welding area between the headlight wiring harness 107 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 wiring harness 107 and the wiring harness anti-reverse ring 102. This effectively prevents the headlight wiring harness 107 from coming off the wiring harness anti-reverse ring 102 when under stress. At the same time, the welding protrusion 108 can disperse the tensile force on the headlight wiring harness 107 to a certain extent, so that the tensile force is applied more evenly to the welding part between the headlight wiring harness 107 and the wiring harness anti-reverse ring 102, reducing local stress concentration and extending the service life of the headlight wiring harness 107 and the welding part.

[0018] Furthermore, the diameters of the through hole 105 and the wiring harness connecting sheet metal hole 104 are both larger than the diameter of the headlight wiring harness 107.

[0019] In this embodiment, when installing the headlight wiring harness 107, the larger aperture allows the headlight wiring harness 107 to pass more smoothly through the through hole 105 and the wiring harness connecting sheet metal hole 104, reducing installation difficulty and improving assembly efficiency. Furthermore, during vehicle use, the headlight wiring harness 107 may expand or deform to a certain extent due to factors such as temperature changes. The larger aperture can accommodate these changes, preventing the headlight wiring harness 107 from being damaged due to compression, ensuring the normal use of the headlight wiring harness 107 and the effectiveness of the anti-pull-out device.

[0020] Furthermore, both the outer casing of the vehicle light wiring harness 107 and the wiring harness anti-reverse coil 102 are made of PVC material.

[0021] Furthermore, the diameter range for ultrasonic welding is 10–20 mm, while the diameter range for high-frequency welding is 4–12 mm.

[0022] 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.
