Description

Technical Field

[0001] This utility model relates to the field of automotive lighting wiring harness technology, specifically to a stable automotive lighting wiring harness. Background Technology

[0002] In automotive lighting systems, the headlight wiring harness is a key component connecting the power supply and the headlights, and its stability directly affects vehicle driving safety.

[0003] In existing technologies, vehicle lighting wiring harnesses are typically secured to the main wiring harness using cable ties. This method has significant drawbacks: cable ties provide rigid fixation, and when the vehicle travels over bumpy or complex road conditions, the frequent vibrations of the wiring harness can easily cause the cable ties to break, leading to loosening of the wiring harness and resulting in poor circuit contact or even short circuits.

[0004] In addition, the layout of headlights and wiring harnesses vary greatly among different car models. Traditional wiring harnesses need to be customized in length and fixed in position according to the car model, which not only increases the research and development and production costs, but also requires cutting the cable ties and re-fixing during later maintenance, resulting in poor universality and maintainability. Summary of the Invention

[0005] The purpose of this invention is to provide a stable vehicle lighting wiring harness to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable vehicle headlight wiring harness, comprising a main wiring harness and two sets of wiring harnesses, the two sets of wiring harnesses being fixedly connected to both sides of the main wiring harness, a sleeve being fitted onto the outer wall of the main wiring harness, a limiting component being fixedly connected to the surface of the sleeve, the limiting component comprising a fixing seat being fixedly connected to the surface of the sleeve, slots being provided on both sides of the fixing seat, a notch being provided on the side wall of the fixing seat, a limiting block being slidably connected inside the notch, and a cross plate being fixedly connected to the top of the limiting block.

[0007] Preferably, the inner wall of the sleeve is provided with a fixing component, the fixing component including a movable groove, the movable groove being formed on the inner wall of the sleeve, a pressure plate being slidably connected inside the movable groove, and a threaded rod being rotatably connected to the bottom surface of the pressure plate.

[0008] Preferably, the surface of the horizontal plate has a through hole, and a positioning rod is slidably connected in the through hole. One end of the positioning rod is fixedly connected to the surface of the fixed base, and the other end of the positioning rod is fixedly connected to a protrusion.

[0009] Preferably, the protrusion and the cross plate are elastically connected by a return spring, and the return spring is sleeved on the outer wall of the positioning rod.

[0010] Preferably, an anti-slip rubber pad is fixedly connected to the surface of the pressure plate.

[0011] Preferably, the threaded rod passes through and is threadedly connected to the outer wall of the sleeve, and a rotating wheel is fixedly connected to the bottom end of the threaded rod.

[0012] Compared with the prior art, this utility model provides a vehicle headlight wiring harness with stable connection, which has the following advantages:

[0013] 1. This stable headlight wiring harness has its branch harness inserted into the slot and then aligned with the main harness, reducing mutual friction or scraping against body parts caused by loose wiring harnesses. Furthermore, the limiting component uses a reset spring to push the limiting block to limit the branch harness, thereby preventing the branch harness from loosening due to vibration breakage when the vehicle passes over bumpy roads, which is common with traditional cable ties, thus improving the stability of the headlight wiring harness connection.

[0014] 2. This stable headlight wiring harness uses a threaded rod to drive a pressure plate and an anti-slip rubber pad to fix and slide the sleeve to the main wiring harness. This allows the sleeve to slide freely along the direction of the main wiring harness, adapting to the wiring harness layout requirements of different vehicle models. No customized wiring harness is required, reducing production costs. Attached Figure Description

[0019] like Figures 1-3As shown, this utility model provides a technical solution: a stable vehicle headlight wiring harness, including a main wiring harness 1 and two sets of wiring harnesses 2. The two sets of wiring harnesses 2 are fixedly connected to both sides of the main wiring harness 1. A sleeve 3 is fitted onto the outer wall of the main wiring harness 1. The sleeve 3 can slide along the outer wall of the main wiring harness 1, thereby adjusting the position of the sleeve 3 and the limiting component 4. The limiting component 4 is fixedly connected to the surface of the sleeve 3. The limiting component 4 includes a fixing seat 41, which is fixedly connected to the surface of the sleeve 3. Both sides of the fixing seat 41 are provided with insertion slots 42. The cross-section of the insertion slots 42 is U-shaped, used to insert the branch wiring harnesses 2, so that the branch wiring harnesses 2 are brought together with the main wiring harness 1, reducing the looseness of the wiring harness and improving the vibration resistance.

[0020] like Figures 1-3 As shown, the side wall of the fixed base 41 has a notch 43, and a limiting block 44 is slidably connected inside the notch 43. A horizontal plate 45 is fixedly connected to the top of the limiting block 44. A through hole is opened on the surface of the horizontal plate 45, and a positioning rod 46 is slidably connected in the through hole. One end of the positioning rod 46 is fixedly connected to the surface of the fixed base 41. The positioning rod 46 positions and guides the horizontal plate 45, so that the limiting block 44 slides horizontally through the notch 43, thereby inserting or retracting into the slot 42. The other end of the positioning rod 46 is fixedly connected to a protrusion 47. The protrusion 47 and the horizontal plate 45 are elastically connected by a return spring 48, which is sleeved on the outer wall of the positioning rod 46. The return spring 48 pushes the horizontal plate 45 and the limiting block 44 to move towards the insertion slot 42, locking the branch wire harness 2 and preventing it from coming out of the insertion slot 42. During disassembly, the horizontal plate 45 is pulled upward to compress the return spring 48, which drives the limiting block 44 out of the insertion slot 42, releasing the fixing of the branch wire harness 2 and making it easier to take the branch wire harness 2 out of the insertion slot 42.

[0021] like Figures 1-3 As shown, the inner wall of the sleeve 3 is provided with a fixing component 5, which includes a movable groove 51. The movable groove 51 is formed on the inner wall of the sleeve 3, providing space for the pressure plate 52 and the anti-slip rubber pad 53 to move. The pressure plate 52 is slidably connected inside the movable groove 51, and the anti-slip rubber pad 53 is fixedly connected to the surface of the pressure plate 52. A threaded rod 54 is rotatably connected to the bottom surface of the pressure plate 52. The threaded rod 54 passes through and is threadedly connected to the outer wall of the sleeve 3. A rotating wheel 55 is fixedly connected to the bottom end of the threaded rod 54. The surface of the anti-slip rubber pad 53 has teeth. By rotating the rotating wheel 55, the threaded rod 54 is rotated, causing the pressure plate 52 to move the anti-slip rubber pad 53 closer to the center of the sleeve 3 and tightly fit it against the outer wall of the main wire harness 1, so that the position of the sleeve 3 can be adjusted and fixed.

[0022] In this utility model, when in use, rotating the wheel 55 counterclockwise causes the pressure plate 52 to retract, and the sleeve 3 can slide freely to adjust its position, so that the limiting component 4 and the branch wire harness 2 are in a suitable position. By rotating the wheel 55, the threaded rod 54 is rotated, so that the pressure plate 52 drives the anti-slip rubber pad 53 to approach the center of the sleeve 3 and fit tightly against the outer wall of the main wire harness 1, so that the position of the sleeve 3 is fixed.

[0023] Two sets of wire harnesses 2 are inserted into the U-shaped insertion slots 42 on both sides of the fixing base 41, so that the wire harnesses 2 fit against the outer wall of the main wire harness 1 and form a closed state, reducing vibration and wear caused by loose wire harnesses. The return spring 48 pushes the horizontal plate 45 and the limiting block 44 to move towards the insertion slot 42, locking the wire harnesses 2 and preventing them from coming out of the insertion slot 42. During disassembly, the horizontal plate 45 is pulled upward to compress the return spring 48, which drives the limiting block 44 out of the insertion slot 42, releasing the fixing of the wire harnesses 2 and making it easy to take the wire harnesses 2 out of the insertion slot 42.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
