Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, specifically a plastic bracket with a new mounting structure for automotive wiring harnesses. Background Technology

[0002] With the rapid popularization of automotive intelligence, the number of automotive electronic components used continues to increase. As a result, the use of wire harnesses and matching connectors, which serve as the signal and power transmission paths for electronic components, is also expanding. The demand for integration of "wire harness constraint, component fixation, and component support" in areas such as the front compartment of automobiles is becoming increasingly urgent.

[0003] In existing technologies, a combination of "independent electrical box + single-function bracket" is usually used to meet the above requirements. However, this approach has many drawbacks: First, traditional electrical boxes are bulky and inconvenient to install and operate, while ordinary brackets have a single function. To meet the support, fixation, and angle requirements of the front compartment of a car, additional iron brackets or adjustments to the wiring harness routing are often required, making it difficult to adapt to complex usage scenarios. Second, the distributed functional approach not only has a high space occupancy rate but also increases the procurement and assembly costs for OEMs. Furthermore, the traditional structure lacks a design for storing and isolating wire ends, which can easily lead to wire contact and electrical conduction, as well as interference from wire contact. At the same time, the fixing parts are mostly made of a single plastic material, which has insufficient strength and wear resistance. The sealing and protection of the installation connection points are also poor, making them susceptible to dust and moisture, resulting in reduced component durability.

[0004] The aforementioned issues present significant challenges for OEMs in balancing functionality, cost, space, and reliability. Therefore, there is an urgent need for a highly integrated, adaptable, easy-to-install, and protective wiring harness connection structure to address the problems of poor adaptability, high cost, and insufficient safety and durability of traditional solutions. Utility Model Content

[0005] To address the above problems, this utility model provides a new plastic bracket with a novel mounting structure for automotive wiring harnesses, thus solving the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic bracket with a new hanging structure for automotive wiring harnesses, comprising a bracket body, a plurality of snap-fit ​​fixing springs at the upper end of the bracket body, wire end storage slots on the left and right sides of the snap-fit ​​fixing springs, an isolation plate fixed to the upper end of two adjacent wire end storage slots, a fixing plate at one end of the bracket body, a pre-fixing bolt fixed on the fixing plate, and two reinforcing components at the other end of the bracket body.

[0007] Preferably, the reinforcement component includes a reinforcement plate, each of which has through holes, and a metal bushing is fixed inside the through holes.

[0008] Preferably, one end of the wire end storage groove is sealed, one end of the snap-fit ​​fixing spring is fixedly connected to the wire end storage groove, and a gap is provided between the other end of the snap-fit ​​fixing spring and the wire end storage groove to form a slot, and the isolation plate is T-shaped.

[0009] Preferably, the upper end of the fixing plate is provided with a plurality of reinforcing ribs, and the fixing plate is provided with through holes for engaging the pre-fixing bolts.

[0010] Preferably, the pre-fixing bolt includes a limiting plate, a sealing ring is fixed at the lower end of the limiting plate, a gap is provided between the limiting plate and the sealing ring, a plug is fixed at the lower end of the sealing ring, the lower end of the plug is conical, multiple fastening plates are provided on the outer wall of the plug, and the sealing ring and fastening plates are bowl-shaped with their openings facing each other.

[0011] Preferably, the upper end of the limiting plate is fixed with two symmetrical snap-fit ​​parts, the top of the snap-fit ​​parts is provided with a folded edge, and the end face of the folded edge is provided with a snap-fit ​​platform, which is snap-fitted into the through hole of the pre-fixing bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Connectors can be directly assembled by snap-fit ​​fixing springs. The wire end storage slot and T-shaped isolation plate prevent short circuits or interference. At the same time, the main structure supports components such as sheaths and oil pumps, allowing a single bracket to handle the management needs of multiple components. It replaces the traditional scattered solution of "electrical box + independent bracket + wire harness fixing parts", and realizes the three core functions of wire harness management, component fixing and component support in a unified manner.

[0013] 2. The structure, including the snap-fit ​​platform and conical plug-in post, supports rapid installation, eliminating the need for additional fasteners and complex alignment steps. The combination of "plastic body + metal bushing" balances strength and cost. The integrated form not only saves space in the front compartment of the car but also reduces the expenditure on purchasing and assembling multiple components, significantly lowering the overall application cost for OEMs. The sealing ring provides dust and moisture protection for the installation area, the fastening plate prevents the connection from loosening, and the wire end storage and line isolation avoid electrical risks. This not only improves the durability and safety of the components but also precisely meets the comprehensive needs of the front compartment of the car for "stable support, compact space, and controllable cost".

[0016] 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.

[0017] Please see Figure 1 , Figure 2 and Figure 3 A new type of plastic bracket for automotive wiring harnesses includes a bracket body 1. Multiple snap-fit ​​spring clips 13 are evenly distributed on the upper end of the bracket body 1. These snap-fit ​​spring clips 13 employ an elastic structure design, adaptable to connectors or electronic components of different specifications, and can be fixed without additional fasteners, solving the problems of traditional brackets requiring separate fasteners and cumbersome assembly steps. Wire end storage grooves 14 are integrally formed on the left and right sides of each snap-fit ​​spring clip 13. A T-shaped isolation plate 15 is integrally fixed to the upper end of each adjacent wire end storage groove 14. The wire end storage slot 14 adopts a one-end sealed structure, which can be inserted into the slot for temporary storage of unconnected wire ends, avoiding the safety hazard of wire ends coming into contact with electricity and solving the problem of disordered wire ends in traditional wire harness layout; the T-shaped isolation plate 15 can physically separate adjacent lines to prevent lines from sticking together and interfering or short-circuiting, solving the problem of traditional wire harnesses being dense and easily sticking together; a fixing plate 11 extends integrally from one end of the bracket body 1, and a pre-fixing bolt 2 is fixed on the fixing plate 11 by a snap-fit ​​structure, and two reinforcing components 3 are symmetrically arranged at the other end of the bracket body 1.

[0018] Please see Figure 1 , Figure 2 and Figure 3The reinforcing component 3 includes a reinforcing plate 31 integrally connected to the bracket body 1. The reinforcing plate 31 has through holes for installation, and a metal bushing 32 is embedded inside each through hole. The metal bushing 32 significantly improves the strength and wear resistance of the reinforcing plate 31, preventing long-term stress and wear deformation of the plastic material, and solving the problems of insufficient strength and short lifespan of the fixing parts of traditional plastic brackets. One end of the wire end storage groove 14 is sealed, and one end of the snap-fit ​​fixing spring 13 is firmly connected to the wire end storage groove 14, while the other end has a pre-reserved gap with the wire end storage groove 14 to form a snap-fit. The slot can stably hold the wire harness, achieving both rapid positioning of the wire harness and preventing loosening, thus solving the problems of complex and unstable fixing operations in traditional wire harnesses. The isolation plate 15 is T-shaped, which can more stably separate the lines. The upper end of the fixing plate 11 is integrally formed with several reinforcing ribs 12. The fixing plate 11 has through holes for engaging the pre-fixing bolts 2. The reinforcing ribs 12 enhance the structural rigidity of the fixing plate 11, preventing it from bending and deforming under stress, thus solving the problem of insufficient local strength in traditional brackets. The engaging through holes provide precise positioning for the pre-fixing bolts 2, improving assembly efficiency.

[0019] Please see Figure 2 , Figure 3 and Figure 4 The pre-fixing bolt 2 includes a limiting plate 21 adapted to the snap-fit ​​structure. A sealing ring 22 is fixed to the lower end of the limiting plate 21. An adaptation gap is reserved between the limiting plate 21 and the sealing ring 22. A plug-in post 23 is fixed to the lower end of the sealing ring 22. The lower end of the plug-in post 23 is conical, and its outer wall is provided with multiple fastening plates 24 circumferentially. The sealing ring 22 and the fastening plates 24 are bowl-shaped with their openings facing each other. The conical plug-in post 23 can be quickly aligned with the mounting hole in the front compartment of the vehicle body, improving the ease of assembly. The multiple fastening plates 24 can fit tightly against the inner wall of the mounting hole, preventing the pre-fixing bolt 2 from falling off, thus solving the problem of easy loosening of traditional fasteners. The sealing ring 22 The sealable mounting holes provide dust and moisture protection, solving the problem of insufficient protection at the front compartment mounting location. The upper end of the limiting plate 21 is fixed with two symmetrical snap-fit ​​pieces 25. Each snap-fit ​​piece 25 has a folded edge at its top, and snap-fit ​​platforms 251 are respectively provided on the end faces of the folded edges. The snap-fit ​​platforms 251 engage with the through holes of the bracket body 1. This precise engagement allows for quick connection between the pre-fixing bolt 2 and the bracket body 1, simultaneously fixing the bracket to the front compartment of the vehicle. This solves the problem of numerous and time-consuming installation steps in traditional bracket installations. Furthermore, the limiting plate 21 prevents the top of the pre-fixing bolt 2 from penetrating the bracket body 1, avoiding over-assembly.

[0020] Furthermore, these structures work together to achieve an integrated function of "wiring harness management + component fixing + body connection + protective sealing": it not only replaces the traditional combination of "electrical box + bracket", saving space in the front compartment of the car and reducing the procurement and assembly costs of the OEM; but also improves the assembly efficiency, safety and durability of the bracket through flexible snap-fit ​​and sealed isolation design, perfectly meeting the comprehensive needs of the front compartment of the car for component support, space utilization and cost control.

[0021] When using this utility model: First, verify the integrity of each component of the device, including the main body 1, the pre-fixing bolt 2, the reinforcing component 3, and the embedded metal bushing 32. No additional auxiliary components such as electrical boxes and independent wire harness fasteners are required. Thanks to the integrated functional design of the device, the steps of checking and matching multiple components in the traditional solution are eliminated. This not only shortens the preparation time but also reduces the cost pressure of purchasing and storing multiple components. Then, pre-assemble the pre-fixing bolt 2 and the main body 1. Align the snap-fit ​​piece 25 on the pre-fixing bolt 2 with the through hole of the fixing plate 11 in the main body 1, and gently press to make the snap-fit ​​piece 251 accurately snap into the through hole, thus completing the quick fixation of the two.During this process, the limiting plate 21 automatically restricts the installation depth of the pre-fixing bolt 2 to avoid damage to components due to over-assembly. Compared with the traditional bolt fixing method, there is no need to tighten the screws, improving assembly efficiency by more than 50% and significantly reducing the intensity of manual operation. After pre-assembly, the bracket is moved to the preset installation position in the front compartment of the car. First, the pre-fixing bolt 2 is inserted into the corresponding pre-fixing point on the car body to achieve initial support and positioning of the bracket body 1. This pre-support design allows a single person to complete the subsequent operations without the need for assistance from others, solving the cumbersome problems of traditional brackets being large and requiring multiple people to cooperate during positioning. Then, the bracket body 1 is pushed so that the conical insertion post 23 of the pre-fixing bolt 2 aligns with the mounting hole in the front compartment of the car body, and a gentle press completes the initial insertion. The conical end quickly guides the insertion post 23 to align with the hole, avoiding the hassle of repeated alignment adjustments required by traditional straight ends, thus further improving assembly efficiency. Simultaneously, the multi-ringed cup-shaped fastening plates 24 on the outer wall of the insertion post 23 tightly fit against the inner wall of the mounting hole, instantly achieving temporary fixation between the bracket and the vehicle body, preventing bracket misalignment during assembly. Finally, the bracket is ultimately fixed using the reinforcement component 3. Bolts pass through the through holes on the reinforcement plate 31 and the embedded metal bushing 32, locking the bracket body 1 to the preset mounting position on the vehicle body. The metal bushing 32 significantly improves the strength and wear resistance of the fixing part, avoiding the wear and deformation problems that occur with traditional plastic brackets under long-term stress, ensuring the stability of the bracket for long-term use, eliminating the need for frequent maintenance and replacement, and reducing costs. This reduces overall vehicle maintenance costs. Once the bracket body 1 is fixed, the wiring harness and electronic components can be assembled. Simply align the connectors or electronic components to be fixed with the snap-fit ​​spring clips 13 on the upper end of the bracket body 1 and press gently to complete the assembly. The elastic structure of the snap-fit ​​spring clips 13 eliminates the need for additional nuts, clips, or other fasteners, enabling rapid component assembly. It also accommodates components of different specifications, improving the device's versatility. Unconnected wire ends can be directly inserted into the wire end storage slots 14 on both sides of the snap-fit ​​spring clips 13, avoiding the safety hazards of scattered wire ends and short circuits caused by contact in traditional wiring harness arrangements. The T-shaped isolation plates 15 at the upper end of adjacent wire end storage slots 14 automatically separate different lines, preventing signal interference caused by wire contact. Physical wear further ensures the safety and stability of the wiring harness. In addition, the gap between the snap-fit ​​fixing spring 13 and the wire end storage groove 14 can directly clamp the wiring harness, realizing quick positioning and organization of the wiring harness without the need for additional tape wrapping or wiring harness fixing clips, simplifying the organization process. Finally, the installation effect is checked to confirm that the sealing ring 22 on the pre-fixing bolt 2 fits tightly with the vehicle body mounting hole. The sealing ring 22 can effectively seal the connection gap, achieving dustproof and moisture-proof protection, solving the problem of poor sealing performance and susceptibility to the complex environment of the front compartment in traditional bracket installation parts. Check whether the fastening plate 24 is firmly clamped in the mounting hole to ensure that the pre-fixing bolt 2 will not come loose from the hole. Confirm that all wiring harnesses and components are firmly fixed without loosening or displacement.The entire acceptance process is simple and intuitive, requiring no professional testing tools, which further improves assembly efficiency.
