Description

Technical Field

[0001] This utility model relates to the field of wire harness fixing bracket technology, specifically an electrical wire harness installation and fixing device. Background Technology

[0002] Engine wiring harnesses are a crucial component of automotive electrical systems. They are responsible for precisely connecting various electrical devices (such as sensors, actuators, and controllers) to ensure accurate transmission of electrical signals. Given the extremely limited space and complex environment within the engine compartment, wiring harnesses must be carefully arranged and securely fixed to prevent unnecessary interference or wear with surrounding components, thereby maintaining the long-term stability and high reliability of electrical connections. Therefore, the wiring harness bracket, as the core component supporting and securing the wiring harness, plays a vital role in the smooth operation of the entire electrical system through its careful design and superior performance.

[0003] However, existing methods for fixing wire harness brackets often present several problems. For example, many wire harness brackets use direct bolt fixing, but these bolts often protrude from the bracket surface after tightening. This not only affects the overall aesthetics of the bracket but, more importantly, the protruding bolts are prone to friction with the wire harness, leading to wear or even breakage, thus affecting the normal operation of the electrical system. Furthermore, traditional wire harness brackets often require additional tools such as cable ties or tape to secure the wire harness, increasing installation steps and costs. Therefore, developing a wire harness installation and fixing device that effectively solves the above problems is of significant practical importance.

[0004] Therefore, we propose an electrical wiring harness mounting and fixing device. Utility Model Content

[0005] The purpose of this invention is to provide an electrical wiring harness installation and fixing device to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: including:

[0007] The wire harness bracket and the groove formed on the wire harness bracket, the groove is threaded with a fixing bolt, and after the wire harness bracket is installed by the fixing bolt, the top end face of the fixing bolt and the top surface of the wire harness bracket are on the same plane.

[0008] The rotating plate is connected to the rotating shaft via a rotating clamping plate. The rotating shaft is rotatably mounted on the wire harness bracket. A clamping mechanism is also provided between the wire harness bracket and the rotating clamping plate. When the wire harness bracket is installed by tightening the fixing bolts, the clamping mechanism drives the rotating clamping plate to flip towards the wire harness side, thereby clamping the wire harness.

[0009] As a further description of the above technical solution: the clamping mechanism includes a wedge-shaped slider mounted on a telescopic connecting rod, the telescopic connecting rod being installed in a slot at the bottom of the wire harness bracket, and the end of the rotating plate abutting against the inclined surface of the wedge-shaped slider via a sliding roller.

[0010] As a further description of the above technical solution: after the wire harness bracket is installed by tightening the fixing bolt, the inclined surface of the wedge-shaped slider does not disengage from the sliding roller.

[0011] As a further description of the above technical solution: when the fixing bolt is tightened to its maximum stroke to complete the installation of the wire harness bracket, the wedge-shaped slider forms a support, creating a gap between the wire harness bracket and the mounting plane.

[0012] As a further description of the above technical solution: the installation position of the rotating shaft is located at the axial center of the arc-shaped part of the rotating plate.

[0013] As a further description of the above technical solution: the rotating plate is made of fluororubber.

[0014] In the above technical solution, the electrical wiring harness installation and fixing device provided by this utility model has the following beneficial effects:

[0015] 1. Prevent wear and maintain aesthetics: The top surface of the fixing bolt is flush with the top surface of the wire harness bracket after installation, which effectively prevents wire harness wear caused by bolt protrusion, while maintaining the overall aesthetics of the structure.

[0016] 2. Simplified installation steps: The device integrates a clamping mechanism, which allows the wire harness to be clamped and fixed at the same time as the wire harness bracket is installed, eliminating the need for additional tools such as cable ties or tape, greatly simplifying the installation steps and improving installation efficiency.

[0017] 3. Enhanced fixing effect: The clamping mechanism drives the rotating plate to flip and clamp the wire harness, ensuring the stability of the wire harness installation and effectively preventing the wire harness from loosening or falling off during use.

[0018] 4. Improved heat dissipation performance: When the fixing bolts are tightened to the maximum stroke to complete the installation, the wedge-shaped slider forms a support, creating a gap between the wire harness bracket and the mounting surface. This facilitates heat dissipation of the wire harness and the device itself, preventing overheating and material damage. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-3 This utility model embodiment provides a technical solution including:

[0027] The wire harness bracket 1 and the groove 2 formed on the wire harness bracket 1 are provided. The groove 2 is threaded with a fixing bolt 3. After the wire harness bracket 1 is installed by the fixing bolt 3, the top end face of the fixing bolt 3 is on the same plane as the top surface of the wire harness bracket 1. After the wire harness bracket 1 is installed, the top end face of the fixing bolt 3 used for installing the wire harness is flush with the end face of the wire harness bracket 1. This can prevent the bolt and nut from protruding and wearing the wire harness. The overall structure is simple and practical. The fixing bolt 3 will not protrude, maintaining the appearance. It protects the wire harness from damage in the original way and solves the problem that after the wire harness bracket 1 is assembled, the fixing bolt 3 protrudes, affecting the installation and routing of the wire harness and causing wire harness wear.

[0028] To improve the fixing effect of the wire harness, the electrical wire harness installation and fixing device also includes a rotating clamping plate 8 connected to the rotating shaft 5 via a connecting rotating plate 7. The rotating shaft 5 is rotatably mounted on the wire harness bracket 1, and a clamping mechanism is also provided between the wire harness bracket 1 and the rotating clamping plate 8. When the wire harness bracket 1 is installed by tightening the fixing bolt 3, the clamping mechanism drives the rotating clamping plate 8 to flip towards the wire harness side, thereby clamping the wire harness. Thus, during installation, the wire harness to be installed is first placed on the wire harness bracket 1, then the wire harness bracket 1 is placed in the position to be installed, and then the wire harness bracket 1 is installed in the position to be installed by the fixing bolt 3. During the installation of the wire harness bracket 1, the clamping mechanism drives the rotating clamping plate 8 to rotate, thereby clamping and fixing the wire harness. After the wire harness bracket 1 is installed, there is no need to use additional tools such as cable ties or tape to install the wire harness on the wire harness bracket 1. Instead, the wire harness is fixed during the installation of the wire harness bracket 1, which can be completed in one step, improving the convenience of installation.

[0029] In one embodiment of this utility model, the clamping mechanism includes a wedge-shaped slider 4 mounted on a telescopic connecting rod 9. The telescopic connecting rod 9 is installed in a groove at the bottom of the wire harness bracket 1. The end of the rotating plate 8 abuts against the inclined surface of the wedge-shaped slider 4 via a sliding roller 6. When the wire harness bracket 1 is installed by tightening the fixing bolt 3, the wedge-shaped slider 4 is the first position to abut against the surface of the installation position. As the fixing bolt 3 is tightened, the wedge-shaped slider 4 will gradually insert into the groove. At this time, the inclined surface of the wedge-shaped slider 4 can push the rotating plate 8 by abutting against the sliding roller 6, thereby rotating the rotating plate 8 and realizing the clamping action of the wire harness.

[0030] In order for the rotating plate 8 to rotate, the mounting position of the rotating shaft 5 is located at the axis center of the arc-shaped part of the rotating plate 8;

[0031] It should be noted that after the wire harness bracket 1 is installed by tightening the fixing bolt 3, the inclined surface of the wedge slider 4 does not disengage from the sliding roller 6. At this time, the inclined surface of the wedge slider 4 can continuously abut against the sliding roller 6, thereby keeping the position of the rotating plate 8 fixed and preventing the wire harness from falling off after installation.

[0032] Furthermore, when the fixing bolt 3 is tightened to its maximum stroke to complete the installation of the wire harness bracket 1, the wedge-shaped slider 4 provides support, creating a gap between the wire harness bracket 1 and the mounting surface. This prevents the wire harness bracket 1 from directly contacting the surface of the mounting location, instead maintaining a certain gap between the wire harness bracket 1 and the mounting location. This improves heat dissipation and prevents overheating that could damage the material of the wire harness bracket 1. The wedge-shaped slider 4 simultaneously presses and fixes the wire harness while installing the wire harness bracket 1, and also forms a flow channel between the wire harness bracket 1 and the mounting surface, preventing overheating and material damage caused by close contact. It has excellent performance and is suitable for widespread use.

[0033] Furthermore, the rotating plate 8 is made of fluororubber, which prevents corrosion and improves the overall service life.

[0034] Working Principle: When using this electrical wiring harness installation and fixing device, first place the wiring harness to be installed on the wiring harness bracket 1, ensuring the wiring harness is in the correct position; then, place the wiring harness bracket 1 together with the wiring harness on it at the target installation position. At this time, the wedge-shaped slider 4 first contacts the installation surface; next, start installing the wiring harness bracket 1 by tightening the fixing bolt 3. As the fixing bolt 3 is tightened, the wedge-shaped slider 4 is gradually pressed into the groove at the bottom of the wiring harness bracket 1. Its inclined surface pushes the rotating plate 8 to rotate around the rotating shaft 5 through the sliding roller 6. The rotating plate 8 gradually flips towards the wiring harness side and presses the wiring harness; when the fixing bolt 3 is tightened to the maximum stroke to complete the installation, the wedge-shaped slider 4 not only completes the pressing and fixing of the wiring harness, but also acts as a support to create a gap between the wiring harness bracket 1 and the installation surface, improving the heat dissipation effect, and preventing the material of the wiring harness bracket 1 from being damaged due to overheating. The entire installation process is completed in one step without the need for additional tools, which is both convenient and efficient.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
