Technical Field
[0001] This utility model relates to the field of wire harness bracket technology, specifically a wire harness bracket with stud snap-fit. Background Technology
[0002] Automotive wiring harness brackets are a crucial component of automotive electrical systems. They primarily secure and support the wiring harnesses, ensuring they are not damaged or displaced during vehicle operation due to vibration, friction, or other factors. In automotive manufacturing, high-quality wiring harness brackets are essential for ensuring the stability and reliability of the automotive electrical system. They help reduce electrical faults and improve the overall performance and safety of the vehicle. This has led OEMs to place increasingly higher demands on brackets. However, this also presents challenges: given the integration of numerous essential automotive components and the size limitations of the vehicle, brackets may encounter issues, such as insufficient space for installation. Wiring harness brackets are generally elongated, consisting of an inlet connecting to a cable tray and then to an outlet. Due to their vital role in the vehicle, market demands for wiring harness brackets have gradually increased. They must not only meet performance requirements such as securing and protecting the wiring harness but also ensure proper installation during automotive manufacturing. However, some common wiring harness brackets, due to their structural limitations, no longer meet the assembly requirements in certain situations, such as narrow mounting points. Utility Model Content
[0003] To address the above problems, this utility model provides a stud-locked wire harness bracket, thus solving the aforementioned issues.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a stud-connected wire harness bracket, comprising a bracket body, a stud, a snap-fit structure, and a vehicle body sheet metal, wherein the stud is inside the snap-fit structure, and the bracket body is fixedly connected to the vehicle body sheet metal via the stud; A sealing cap is snapped into the snap-fit structure. Clamping blocks are symmetrically arranged inside the snap-fit structure. Snap-fit grooves are symmetrically opened inside the snap-fit structure and are located above the clamping blocks. The snap-fit structure snaps into the sealing cap through the snap-fit grooves, and the clamping blocks hold the stud.
[0005] Preferably, the inner wall of the snap-fit structure is symmetrically fixed with limiting blocks, and the end of the limiting block near the body sheet metal is provided with an inclined surface. The limiting blocks are located between each pair of snap-fit grooves, and a gap is provided between the two limiting blocks, the gap decreasing from top to bottom.
[0006] Preferably, the bracket body has multiple cable tie holes, which are located on both sides of the snap-fit structure.
[0007] Preferably, the lower end of the sealing cover is provided with two symmetrical plug-in plates, and the outer side of each plug-in plate is provided with a snap-in block corresponding to the snap-in groove.
[0008] Preferably, the lower end of the plug-in plate is provided with a through cavity, and the through cavity is inserted into the inner side of the bending of the clamping block.
[0009] Preferably, the lower end of the sealing cap is fixed with a fixing post, the fixing post is located between two plug plates, the fixing post has a countersunk hole inside, the countersunk hole is frustoconical, the lower end of the countersunk hole has a large opening, and the fixing post corresponds to the stud.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The stud snap-fit structure eliminates the need for tools and large operating space. Simply align the snap-fit structure with the stud and insert it to secure the device. This allows for efficient assembly even in narrow areas of the vehicle body (such as engine compartment corners or interior trim gaps), significantly improving the installation efficiency of the automotive production line. It solves the problem of traditional brackets being unable to be installed in narrow spaces due to structural limitations. The sealing cover also uses a snap-fit assembly, requiring no tools and securing it firmly with a single insertion, further simplifying the assembly process.
[0011] 2. The limiting blocks in the snap-fit structure have a gradual gap, which can gradually limit the lateral displacement of the stud when it is snapped in; the clamping blocks elastically clamp the stud from both sides, realizing the "self-guiding + self-locking" of the stud, which can effectively resist the vibration and impact during vehicle operation and ensure the long-term installation stability of the bracket. The fixing post of the sealing cover has a frustum-shaped countersunk hole, which corresponds to the top of the stud for limiting and further reinforces the connection from the axial direction, so that the stud can be stably fixed in three-dimensional space.
[0012] 3. The cable tray of the bracket body can accommodate the wire harness, and the cable tie hole can further fix the wire harness with cable ties to prevent the wire harness from being damaged or displaced due to vibration and friction during vehicle operation, thereby reducing the probability of electrical faults. The presence of the sealing cover can effectively prevent dust and water, protect the internal snap-fit structure and studs, and also indirectly protect the installation environment of the wire harness, extending the service life of the wire harness and the bracket.

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0016] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A stud-connected wire harness bracket includes a bracket body 1, studs 2, a snap-fit structure 3, and a vehicle body sheet metal 4. The studs 2 are located inside the snap-fit structure 3. The bracket body 1 is fixedly connected to the vehicle body sheet metal 4 via the studs 2. A sealing cap 5 is snap-fitted onto the snap-fit structure 3. The snap-fit structure 3 has symmetrically arranged clamping blocks 33 inside, which allows for elastic clamping of the studs 2 from both sides, ensuring a tight and secure connection between the studs 2 and the snap-fit structure 3, thus solving the problem of traditional brackets easily loosening during vehicle vibration. The snap-fit structure 3 has symmetrically arranged snap-fit grooves 32 inside, located above the clamping blocks 33. The snap-fit structure 3 is snapped into the sealing cap 5 via the snap-fit grooves 32. The design allows for tool-free assembly of the sealing cap 5, enabling it to snap into place instantly, thus improving assembly efficiency. The clamping block 33 holds the stud 2, ensuring its stability within the snap-fit structure 3. The inner wall of the snap-fit structure 3 is symmetrically fixed with limiting blocks 31. One end of each limiting block 31 near the body sheet metal 4 has an inclined surface. The limiting blocks 31 are located between each pair of snap-fit grooves 32, with a gap between them that decreases from top to bottom. The inclined surface design facilitates the quick insertion of the stud 2 into the snap-fit structure 3, while the gradually decreasing gap gradually restricts the lateral displacement of the stud 2 as it snaps into the snap-fit structure 3, achieving "self-guiding + self-locking." This solves the problems of difficult alignment and unstable fixation of the stud 2 in narrow spaces.
[0017] Please see Figure 4 , Figure 5 and Figure 6The bracket body 1 has multiple cable tie holes 11 located on both sides of the snap-fit structure 3. Cable ties can be used to further fix the wire harness to the bracket body 1, preventing the wire harness from moving within the wire protection groove of the bracket body 1 and improving the reliability of the wire harness fixation. At the same time, after the cable tie passes through the cable tie hole 11, part of the force of the cable tie can be applied to the sealing cover 5, further ensuring the firmness of the connection between the sealing cover 5 and the snap-fit structure 3. The lower end of the sealing cover 5 is provided with two symmetrical plug-in plates 51. The outer side of the plug-in plates 51 is provided with snap-fit blocks 52 corresponding to the snap-fit grooves 32. The cooperation between the plug-in plates 51 and the snap-fit grooves 32 makes the installation of the sealing cover 5 precise and firm. At the same time, the sealing cover 5 can effectively prevent dust and water, protecting the internal snap-fit structure 3.
[0018] Please see Figure 5 and Figure 6 The lower end of the plug-in plate 51 is provided with a through cavity 53. The through cavity 53 is inserted into the inner side of the bending of the clamping block 33. The cooperation between the through cavity 53 and the clamping block 33 further strengthens the connection strength between the sealing cover 5 and the snap-fit structure 3, preventing the sealing cover 5 from loosening. Due to the existence of the through cavity 53, the lower end of the plug-in plate 51 is elastic, which makes the clamping effect of the clamping block 33 on the stud 2 more secure. The lower end of the sealing cover 5 is fixed with a fixing post 54. The fixing post 54 is located between the two plug-in plates 51. The fixing post 54 has a countersunk hole inside. The countersunk hole is frustoconical and has a large opening at the lower end. The fixing post 54 corresponds to the stud 2. The frustoconical countersunk hole can limit the top of the stud 2 and further strengthen the entire snap-fit structure 3 from the axial direction, so that the stud 2 can be stably fixed in three-dimensional space.
[0019] Furthermore, this design achieves three core values through the combined use of the wiring harness load-bearing capacity of the bracket body 1, the self-locking installation of the studs 2 in the snap-fit structure 3, and the protection and secondary reinforcement of the sealing cover 5: Installation compatibility: No tools or large operating space are required. Assembly can be completed at any narrow fixing point on the vehicle body, solving the pain point of traditional brackets being "limited by space and unable to be installed"; Wire harness reliability: Wire protection groove + 11 cable tie holes + multi-dimensional snap-fit, comprehensively prevents wire harness vibration and friction damage, and reduces the risk of electrical failure; Durability and protection: The dustproof and waterproof sealing cover 5 and the anti-vibration locking of the snap-fit structure 3 enable the bracket to work stably for a long time in complex automotive-grade environments, improving the overall safety and reliability of the automotive electrical system.
[0020] When using this utility model: The automotive wiring harness is laid in the cable tray of the bracket body 1. Cable ties are inserted through the cable tie holes 11 to initially secure the harness. The cable tray provides space for the harness, and the cable tie holes 11, in conjunction with the cable ties, provide initial positioning of the harness, preventing it from scattering or shifting during subsequent installation, thus laying a foundation for later assembly. Holding the bracket body 1, the snap-fit structure 3 is aligned with the studs 2 on the body sheet metal 4. Using the inclined guide of the limiting block 31, the studs 2 are guided into the snap-fit groove 32 until the clamping block 33 elastically clamps the studs 2 from both sides, completing the snap-fit fixing of the bracket body 1 to the body. No tools or large operating space are required; assembly can be quickly performed even in narrow areas such as engine compartment corners and interior trim gaps, solving the problem of traditional brackets being "limited by space and unable to be installed." To address the pain point of "self-guiding and self-locking", the gradual gap of the limiting block 31 and the elastic clamping of the clamping block 33 achieve the "self-guiding and self-locking" of the stud 2. After installation, the connection is firm and can resist the vibration and impact during vehicle operation. Align the plug plate 51 of the sealing cover 5 with the corresponding interface of the bracket body 1, so that the snap-fit block 52 snaps into the snap-fit groove 32. At the same time, the through cavity 53 is inserted into the bent inner side of the clamping block 33. The fixing post 54 corresponds to the top of the stud 2 for limiting. The snap-fit assembly of the sealing cover 5 also does not require tools. It is firmly inserted and secure. After assembly, it can effectively prevent dust and water, protect the internal snap-fit structure 3 and the stud 2, and extend the service life of the bracket body 1. The frustum-shaped countersunk hole of the fixing post 54 further reinforces the stud 2 from the axial direction, making the entire connection stable and reliable in three-dimensional space.
[0021] Through the above steps, the wiring harness bracket completes the entire process from "wiring harness fixing" to "vehicle installation" and then to "protection and sealing". At each step, structural innovation has achieved the advantages of improved installation efficiency, enhanced space adaptability, and more reliable wiring harness protection, perfectly meeting the dual high requirements of "performance + assembly" for brackets in automobile manufacturing.
