Description

Technical Field

[0001] This application relates to the technical field of sealing components, and in particular to a sealing plug with a fixed linear orientation. Background Technology

[0002] Automotive wiring harness sealing plugs are elastic rubber or silicone elements installed where automotive wiring harnesses pass through body panel holes, wiring harness connectors, etc. The core function of the sealing plug is to fill the gaps between the wiring harness and the mounting hole, and between the wiring harness and the connector housing, through its own compression and deformation, forming a sealed and protective structure.

[0003] However, most existing sealing plugs only provide a sealing function and are insufficient to fix and limit the routing of the wiring harness passing through them. During vehicle operation, vibrations and bumps can cause the wiring harness to shift and twist within the sealing plug. This can not only damage the integrity of the sealing structure and cause seal failure, but also cause the wiring harness to rub against the inner wall of the sealing plug and the edges of the mounting holes. Over time, this can easily lead to wear of the wiring harness insulation layer, causing safety hazards such as short circuits and leakage. Furthermore, a disordered wiring harness routing also hinders later inspection and maintenance. Utility Model Content

[0004] In order to achieve fixed limiting of the wiring harness direction, improve sealing stability, reduce safety hazards, and facilitate later inspection and maintenance, this application provides a sealing plug with fixed wiring harness direction.

[0005] This application provides a sealing plug with a fixed linear orientation, employing the following technical solution: A sealing plug with a fixed linear orientation includes a plug body, which is divided into a first mounting part and a second mounting part. The first mounting part is connected to a component inside a vehicle, and the second mounting part is connected to a wiring harness. The first mounting part and the second mounting part are integrally formed. The second mounting part has a wiring channel inside according to the wiring harness orientation. The connection between the second mounting part and the first mounting part is bent according to the wiring harness orientation. The second mounting part is provided with a first limiting component and a second limiting component. The first limiting component and the second limiting component are respectively provided on the inlet and outlet ends of the wiring harness on the second mounting part and are used to fix the position of the wiring harness.

[0006] By adopting the above technical solution, the first mounting part of the plug body is connected to the vehicle's internal components to achieve fixed installation of the sealing plug. The second mounting part, through its integrated molding structure design, combined with the internal wiring channel that conforms to the wiring harness's direction, and the bending structure at the connection with the first mounting part, comprehensively defines the wiring harness's trajectory. Simultaneously, the first and second limiting components respectively provide double fixation for the wiring harness at its inlet and outlet ends in the second mounting part, effectively preventing the wiring harness from shifting or twisting within the sealing plug. This ensures the integrity of the sealing structure, reduces safety hazards caused by wear on the wiring harness insulation layer, and also makes the wiring harness route regular, facilitating later inspection and maintenance.

[0007] Optionally, an annular protrusion is provided on the outer wall of the first mounting part. The annular protrusion is evenly distributed along the circumference of the first mounting part, and the annular protrusion is interference-fitted with the mounting hole of the vehicle internal component.

[0008] By adopting the above technical solution, the annular protrusion is evenly distributed along the circumference of the first mounting part, forming an interference fit with the mounting hole of the vehicle internal component. This enhances the tightness of the connection between the first mounting part and the mounting hole, not only improving the stability of the sealing plug after installation and reducing the loosening of the sealing plug when the vehicle vibrates, but also further optimizing the sealing effect, effectively preventing external dust, moisture and other substances from entering the vehicle interior through the gap between the mounting hole and the first mounting part.

[0009] Optionally, the first limiting component is an elastic limiting piece, and a plurality of elastic limiting pieces are provided. All of the elastic limiting pieces are provided on the inner sidewall of the end where the second mounting part is connected to the first mounting part. When the wire harness passes through the wiring channel, the elastic limiting piece deforms and abuts against the wire harness.

[0010] By adopting the above technical solution, several elastic limiting pieces are disposed on the inner sidewall of the second mounting part near the first mounting part. When the wire harness passes through the wiring channel, the elastic limiting pieces are compressed by the wire harness and undergo elastic deformation. They then use their own elastic restoring force to tightly press against the surface of the wire harness, thereby achieving elastic clamping and fixing of one end of the wire harness. This design not only adapts to wire harnesses of different diameters and specifications, making it highly versatile, but also ensures a secure fixation while avoiding hard damage to the wire harness insulation layer through its elastic clamping method.

[0011] Optionally, the second limiting component is a second limiting ring, which is disposed at the end of the second mounting portion away from the first mounting portion. The second limiting ring is a deformable second limiting ring made of rubber material, and the diameter of the second limiting ring decreases from the end where the second limiting ring is connected to the second mounting portion toward the direction away from the second mounting portion.

[0012] By adopting the above technical solution, the second limiting ring is made of rubber and has deformable characteristics. Its diameter is designed to gradually decrease from the end connected to the second mounting part to the free end. This structure allows the wire harness to pass smoothly through the second limiting ring by utilizing the deformation characteristics of the second limiting ring. At the same time, the gradually decreasing diameter structure provides a continuous wrapping and limiting effect on the wire harness, further strengthening the fixing effect on the other end of the wire harness. Together with the first limiting component, it achieves double limiting at both ends of the wire harness, effectively preventing axial movement of the wire harness within the wiring channel.

[0013] Optionally, a tightening rubber ring is fitted on the outer wall of the second limiting ring. The tightening rubber ring is made of deformable rubber material and has a diameter smaller than that of the second limiting ring. The tightening rubber ring is fitted on the outer wall of the second limiting ring and is used to tighten the second limiting ring.

[0014] By adopting the above technical solution, the diameter of the tightening rubber ring is smaller than that of the second limiting ring. After being fitted onto the outer wall of the second limiting ring, it generates a continuous radial tightening force on the second limiting ring, causing the second limiting ring to tightly wrap around the surface of the wire harness. This significantly improves the fixing strength and sealing effect of the second limiting ring on the wire harness. Simultaneously, the rubber tightening rubber ring has good deformation capacity, adapting to the deformation of the second limiting ring without causing damage, further ensuring the stability and reliability of the wire harness fixing.

[0015] Optionally, the bending angle of the second mounting part is 30°-120°, and the bending point of the second mounting part adopts a rounded transition.

[0016] By adopting the above technical solution, the bending angle of 30°-120° covers most of the routing requirements in the automotive wiring harness installation process, improving the versatility of the sealing plug. The rounded transition design at the bend avoids hard friction between the wiring harness and the inner wall of the second mounting part at the bend, reducing wear on the wiring harness insulation layer, extending the service life of the wiring harness, and also making the routing of the wiring harness in the wiring channel smoother, reducing stress concentration caused by bending.

[0017] Optionally, a reinforcing rib is provided at the connection between the first mounting part and the second mounting part.

[0018] By adopting the above technical solution, the reinforcing rib can enhance the structural strength of the connection between the first mounting part and the second mounting part. Since the second mounting part has a bent structure, the connection is prone to breakage or deformation under vehicle vibration and external force. The setting of the reinforcing rib effectively improves the deformation resistance and durability of this part, extends the overall service life of the sealing plug, and ensures the long-term stability of the wire harness fixing and sealing effect.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the integrated molding design of the first and second mounting parts, the wiring channel that conforms to the direction of the wire harness, the bending structure, and the limiting components at both ends, the wire harness direction is effectively fixed and limited, avoiding wire harness displacement and twisting, ensuring the integrity of the sealing structure, reducing safety hazards, and facilitating later maintenance. 2. The interference fit between the annular protrusion of the first mounting part and the mounting hole improves the stability and sealing effect of the sealing plug installation, preventing external impurities from entering the vehicle interior; 3. The reasonable bending angle and arc transition design of the second mounting part, as well as the reinforcing ribs at the connection, improve the versatility and durability of the sealing plug and extend the service life of the wire harness and sealing plug.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0023] This application discloses a sealing plug with a fixed linear orientation.

[0024] Reference Figure 1 and Figure 2 The fixed linear direction sealing plug includes an integrally formed plug body 1. The plug body 1 is divided into a first mounting part 2 and a second mounting part 3. The first mounting part 2 is used to connect with the mounting hole of the vehicle interior component. The outer side wall of the first mounting part 2 has annular protrusions 21 evenly distributed along the circumference. The annular protrusions 21 are interference-fitted with the mounting hole to achieve the fixed installation and initial sealing of the sealing plug.

[0025] Reference Figure 2 and Figure 3The second mounting part 3 has a wiring channel 31 inside, and the routing of the wiring channel 31 is consistent with the preset routing of the wire harness. The connection between the second mounting part 3 and the first mounting part 2 is bent according to the routing of the wire harness, with a bending angle of 30°-120°. In this embodiment, 90° is preferred, and the bend 32 adopts an arc transition. A reinforcing rib 7 is also provided at the connection between the first mounting part 2 and the second mounting part 3 to enhance the structural strength of this part.

[0026] Reference Figure 2 and Figure 3 The second mounting part 3 is provided with a first limiting component 4 and a second limiting component 5. The first limiting component 4 and the second limiting component 5 are respectively provided on the inlet and outlet ends of the wire harness on the second mounting part 3 and are used to fix the position of the wire harness.

[0027] Reference Figure 2 and Figure 3 The first limiting component 4 is an elastic limiting piece, and several elastic limiting pieces are provided. Several elastic limiting pieces are evenly distributed and fixedly installed on the inner side wall of the end where the second mounting part 3 is connected to the first mounting part 2. When the wire harness passes through the wiring channel 31, the elastic limiting pieces are squeezed by the wire harness and undergo elastic deformation. They use their own elastic restoring force to tightly press against the surface of the wire harness, thereby achieving elastic clamping and fixing of one end of the wire harness.

[0028] Reference Figure 2 The second limiting component 5 is a second limiting ring, which is fixedly installed at the end of the second mounting part 3 away from the first mounting part 2. The second limiting ring is a deformable second limiting ring made of rubber. The diameter of the second limiting ring gradually decreases from the end where the second limiting ring is connected to the second mounting part 3 towards the end away from the second mounting part 3. This structure allows the wire harness to pass smoothly through the second limiting ring by utilizing the deformation characteristics of the second limiting ring. At the same time, the gradually changing diameter structure provides continuous wrapping and limiting for the wire harness, further strengthening the fixing effect on the other end of the wire harness. Together with the first limiting component 4, it achieves double limiting at both ends of the wire harness, effectively preventing axial movement of the wire harness within the wiring channel 31.

[0029] Reference Figure 2 A tightening rubber ring 6 is fitted onto the outer wall of the second limiting ring. The tightening rubber ring 6 is made of deformable rubber material, and its diameter is smaller than that of the second limiting ring. After the tightening rubber ring 6 is fitted onto the outer wall of the second limiting ring, it will generate a continuous radial tightening force on the second limiting ring, so that the second limiting ring tightly wraps around the surface of the wire harness, significantly improving the fixing strength and sealing effect of the second limiting ring on the wire harness.

[0030] The working principle of this application embodiment is as follows: During installation, the first mounting part 2 is first inserted into the mounting hole of the vehicle's internal components, and the sealing plug is fixed by the interference fit of the annular protrusion 21. Then, the wire harness passes through the wiring channel 31 from one end of the second limiting ring until it exits from the end near the first mounting part 2. At this time, the elastic limiting piece deforms and presses against the wire harness, while the rubber ring 6 tightens the second limiting ring, so that the second limiting ring wraps around the wire harness, achieving double fixation at both ends of the wire harness. The bending structure of the second mounting part 3 and the wiring channel 31 limit the direction of the wire harness, and the reinforcing rib 7 enhances the structural strength of the sealing plug. During vehicle operation, the wire harness will not shift or twist, ensuring the sealing effect and safety of use, and the neat wire harness direction facilitates later maintenance.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
