Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp production, in particular to a novel wire harness fixer. Background Art

[0002] Currently, lamp wiring harnesses require localized fixation to prevent wear and tear from the surrounding body sheet metal or relative movement. Existing solutions typically secure the ends of the harness to the body sheet metal. However, if the harness is long, the central portion of the wire cannot be effectively secured. Installation is also affected by sheet metal thickness and the mating surface of the lamp, resulting in certain limitations. Reference may be made to the existing patent CN217374394U which discloses a new type of wire harness holder, which can be quickly plugged into the mounting hole of the body sheet metal and fixed to the body sheet metal by clamping. Although this type of structure is easy to assemble and disassemble, it cannot effectively fix longer wire harnesses. In addition, additional holes need to be opened in the sheet metal, which challenges the water leakage prevention requirements of the entire vehicle and is not applicable to some vehicles with high environmental requirements. At the same time, this solution only clamps the holder into the hole on the sheet metal, and the sheet metal cannot be provided with an anti-rotation structure, so it cannot avoid the distortion of the wire harness caused by rotation, and there is a risk of breaking the wire harness and failure of the wire harness connection. In addition, this type of holder relies on the deformation of the elastic cantilever to clamp into the hole. If the hole size does not meet the standard or there are multiple layers of sheet metal around the hole, it is easy to cause deformation, resulting in failure to clamp into the hole, which is not conducive to service life. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a new type of wire harness fixer, which has fewer installation restrictions and can fix the wire harness without opening holes in the lamp, thereby preventing the wire harness from twisting and increasing the service life of the wire harness.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A novel wire harness holder comprises an anti-rotation base arranged on the surface of a lamp and a holder assembled on the anti-rotation base and suitable for fixing the wire harness;

[0006] The anti-rotation base includes an integrally formed screw column and a limit platform, one end of the fixer is provided with a cable tie and a matching cable tie hole, and the end of the fixer away from the cable tie is provided with a locking through-hole;

[0007] The locking perforation portion of the fixer is in contact with the screw column and is locked by the fixing screw. The fixer is restricted from rotating by the limit platform. The cable tie cooperates with the cable tie hole to tighten the wire harness.

[0008] Furthermore, anti-rotation ribs for limiting both sides of the fixer are formed on the limiting platform.

[0009] Furthermore, a vertical anti-rotation rib is formed on the limiting platform at a position close to the screw column, and the rib is used to position the fixer.

[0010] Furthermore, a positioning step is provided on the fixer near the locking perforation portion, and the positioning step is in contact with the retaining rib.

[0011] Furthermore, the material of the fixer is PA66.

[0012] By adopting the above technical solution, the utility model has the following beneficial effects:

[0013] 1. The fixer of the utility model can be used to wrap and tighten the wire harness through the combination of the cable tie and the cable tie hole. Multiple anti-rotation bases can be arranged, and multiple fixers can be used to tighten and fix various sections of the wire harness. Therefore, it is suitable for the effective fixation of long wire harnesses and is more convenient and efficient to use.

[0014] 2. The utility model does not require drilling holes on the vehicle body sheet metal or the lamp surface. The anti-rotation base can be directly designed and formed on the lamp surface or the vehicle body sheet metal, and then locked and fixed with the locking perforated portion of the fixer and the screw column of the anti-rotation base. The wiring harness is tightened through the cable tie and cable tie hole of the fixer itself. In this way, the wiring harness can be fixed without drilling holes, which can ensure the sealing of the entire vehicle and prevent water leakage. It is not limited by the wall thickness and surface shape of the lamp, and has a wider range of use and a longer life.

[0015] 3. The utility model locks and fixes the fixing device by means of the screw column on the anti-rotation base and the locking through-hole portion of the fixing device, and limits the position of both sides of the fixing device by means of the limit platform on the anti-rotation base and the anti-rotation rib on the limit platform to prevent the fixing device from rotating, thereby preventing the risk of wiring harness distortion, failure, etc. caused by wiring harness rotation, and thus helping to protect the wiring harness safety.

[0016] 4. The utility model limits the position of the retaining rib on the limit platform and the positioning step on the fixer, which can facilitate the assembly and locking of the fixer and make it easier to lock it in place. At the same time, it can also strengthen the interaction force after locking, prevent the fixer from shaking or loosening, and ensure the stability of the wiring harness fixation.

[0023] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0024] like Figure 1-5 As shown, in this embodiment, a new type of wire harness fixer is provided, which is mainly composed of an anti-rotation base, a fixer 3 and other components. The anti-rotation base is arranged on the lamp surface 5, and the fixer 3 is assembled on the anti-rotation base. The wire harness 6 can be fixed by the fixer 3. The material of the fixer 3 is PA66, which has good mechanical strength and hardness, and increases the service life. Among them, the anti-rotation base specifically includes an integrally formed screw column 1 and a limit table 2. One end of the fixer 3 is provided with a cable tie 31 and a matching cable tie hole 32. The cable tie 31 is wrapped around the wire harness 6 and then inserted into the cable tie hole 32 to tighten it, so as to achieve the purpose of tightening the wire harness 6. At the same time, a locking perforation portion 33 is formed on the end of the fixer 3 away from the cable tie 31. The locking perforation portion 33 of the fixer 3 is in contact with the screw column 1 and is locked by the fixing screw 4. The fixer 3 is restricted from rotating by the limit table 2.

[0025] Specifically, to prevent the wiring harness 6 from rotating, the position-limiting platform 2 of this embodiment is formed with anti-rotation ribs 21 on both sides of the retainer 3. Thus, the screw column 1 on the anti-rotation base and the locking perforation 33 of the retainer 3 are locked and fixed together. Furthermore, the position-limiting platform 2 on the anti-rotation base and the anti-rotation ribs 21 on the position-limiting platform 2 limit the position of the retainer 3 on both sides, preventing rotation. This, in turn, prevents risks such as wiring harness distortion and failure caused by wiring harness rotation, thereby facilitating wiring harness safety.

[0026] To ensure the locking stability of the retainer 3, a retaining rib 22 perpendicular to the anti-rotation rib 21 is formed on the retaining platform 2 of this embodiment near the screw column 1. The retaining rib 22 is used to position the retainer 3. Furthermore, a positioning step 34 is provided on the retainer 3 near the locking perforation 33, which mates with the retaining rib 22. This restraining effect of the retaining rib 22 on the retaining platform 2 and the positioning step 34 on the retainer 3 facilitates the assembly and locking of the retainer 3, making it easier to align and lock the retainer 3. It also strengthens the interaction force after locking, preventing the retainer 3 from shaking or loosening, and ensuring the stability of the wiring harness.

[0027] Through the above design, it can be seen that the fixer 3 of this embodiment can be used to wrap and tighten the wire harness 6 through the combination of the cable tie 31 and the cable tie hole 32. Multiple anti-rotation bases can be arranged, and multiple fixers 3 can be used to tighten and fix various sections of the wire harness. Therefore, it is suitable for effectively fixing long wire harnesses and is more convenient and efficient to use. In addition, this embodiment does not require opening holes in the body sheet metal or the lamp surface. The anti-rotation base can be directly designed and formed on the lamp surface or the body sheet metal, and then the locking perforated portion 33 of the fixer 3 is locked and fixed with the anti-rotation base screw column 1. The cable harness is tightened through the cable tie 31 and the cable tie hole 32 of the fixer 3 itself. In this way, the cable harness can be fixed without opening holes, which can ensure the sealing of the entire vehicle and prevent water leakage. It is not limited by the wall thickness, surface shape, etc. of the lamp, and has a wider range of uses and a longer life.
