Description

Technical Field

[0001] This application relates to the field of automotive wiring harness technology, and more particularly to a rubber component. Background Technology

[0002] Typically, high-quality sound-insulating rubber components have a cavity in the middle, with two rubber tubes at each end of the cavity. These two rubber tubes are then tied to the wiring harness. If the wiring harness needs to branch off immediately at this point on the rubber component, the branch point must be placed outside the area where the rubber tubes are tied to the wiring harness. This results in the branch point being far from the mounting surface of the rubber component. If the environment has limited space or there are other components nearby, the wiring harness branch may interfere with the surrounding components. Utility Model Content

[0003] This application provides a rubber component to solve the technical problem that the distance between the wire harness branch point and the mounting surface of the rubber component is far, thus occupying space.

[0004] Technical solution: This application provides a rubber part, including:

[0005] The body portion has a cavity;

[0006] The cable outlet is disposed on one side of the main body and communicates with the cavity. The cable outlet includes a first branch pipe and a second branch pipe connected together. The first branch pipe and the second branch pipe extend in different directions. The cable outlet has a first outlet and a second outlet. The first outlet is disposed on the first branch pipe and the second outlet is disposed on the second branch pipe.

[0007] Beneficial Effects: The rubber component in this embodiment includes a body and a cable outlet tube. The body has a cavity. The cable outlet tube is disposed on one side of the body and communicates with the cavity. The cable outlet tube includes a first branch tube and a second branch tube connected together. The first branch tube and the second branch tube extend in different directions. The cable outlet tube has a first cable outlet and a second cable outlet. The first cable outlet is disposed on the first branch tube, and the second cable outlet is disposed on the second branch tube. By providing first and second branch tubes with different extension directions, the wire harness can directly branch within the cable outlet tube of the rubber component and be led out from the two cable outlets. This allows the branching point to be close to the body (mounting surface), significantly shortening the distance between the branching point and the mounting surface and avoiding space occupation problems caused by excessively far branching points. Since the branching point is close to the mounting surface, in scenarios with limited environmental space or other components nearby, the probability of interference between the wire harness branch and surrounding components can be reduced without sacrificing the cavity structure of the rubber component to avoid space constraints.

[0017] As an introduction to this application's embodiments, a typical sound-insulating rubber component typically has a cavity 100 in the middle, with two rubber tubes at each end of the cavity 100, which are respectively bound to a wire harness. If the wire harness needs to branch off immediately at the rubber component, the branch point must be placed outside the area where the rubber tubes are bound to the wire harness, making the branch point far from the mounting surface of the rubber component. If the environmental space is limited, or there are other components nearby, the wire harness branch will interfere with the surrounding components. In this case, the cavity 100 must be removed, sacrificing sound insulation, to meet space requirements.

[0018] In view of the above, this application provides a rubber component that aims to solve at least one of the above-mentioned technical problems.

[0019] Please see Figure 1 As shown, this application embodiment provides a rubber component, including a body portion 10 and an outlet tube 30, wherein the body portion 10 has a cavity 100 (e.g., Figure 4The cable outlet 30 is located on one side of the main body 10 and communicates with the cavity 100. The cable outlet 30 includes a first branch pipe 31 and a second branch pipe 32 connected together. The first branch pipe 31 and the second branch pipe 32 extend in different directions. The cable outlet 30 has a first outlet 310 and a second outlet 320. The first outlet 310 is located on the first branch pipe 31, and the second outlet 320 is located on the second branch pipe 32. It should be understood that by setting the first branch pipe 31 and the second branch pipe 32 with different extension directions, the wire harness can directly branch within the cable outlet 30 of the rubber component and be led out from the two outlets. This allows the branching point to be close to the main body 10 (mounting surface), significantly shortening the distance between the branching point and the mounting surface and avoiding space occupation problems caused by the branching point being too far away. Since the branching point is close to the mounting surface, in scenarios with limited environmental space or other components nearby, the probability of interference between the wire harness branching and surrounding components can be reduced without sacrificing the structure of the cavity 100 of the rubber component to avoid space. The cavity 100 structure is retained, ensuring that the rubber components maintain their original sound insulation effect, achieving a balance between sound insulation performance and spatial adaptability. The different extension directions of the two branch pipes can adapt to the wiring harness routing requirements in different spatial directions, enhancing the flexibility and adaptability of the wiring harness layout.

[0020] It should be understood that in this embodiment, the cable outlet 30 has an overall "Y" shaped structure. The first cable outlet 310 is located at the end of the first branch pipe 31 away from the main body 10, and the second cable outlet 320 is located at the end of the second branch pipe 32 away from the main body 10. The edges of both cable outlets are provided with rounded corners to avoid damage to the cable bundle.

[0021] In practical applications, the wire harness enters the cavity 100 from the side of the main body 10 away from the outlet tube 30. After branching within the cavity 100, one wire harness is led out from the first outlet 310 through the first branch tube 31, and the other wire harness is led out from the second outlet 320 through the second branch tube 32. The binding position of the wire harness and the outlet tube 30 can be set outside the first outlet 310 and the second outlet 320. Since the branching point is located inside the cavity 100, close to the mounting surface of the main body 10, the distance between the branching point and the mounting surface is effectively shortened, reducing the risk of interference.

[0022] In some embodiments, three or more branch pipes are provided on the main body 10, such as star-shaped outgoing pipes 30, with different included angles (such as 30°, 60°, 90°, etc.) between each branch pipe to meet the needs of multiple wire harness branches and further improve spatial adaptability.

[0023] In some embodiments, an elastic sealing ring (not shown in the figure) is provided at the first outlet 310 and the second outlet 320. The inner ring of the sealing ring is tightly fitted with the wire harness, and the outer ring is tightly connected with the inner wall of the outlet. This not only enhances the sound insulation effect, but also provides waterproof and dustproof protection, making it suitable for humid or dusty environments.

[0024] Based on the different diameters of the wire harnesses, the first branch pipe 31 and the second branch pipe 32 are designed as variable diameter structures. The pipe diameter at the end closer to the main body 10 is larger, which facilitates the branching operation of the wire harness. The pipe diameter at the end farther from the main body 10 matches the diameter of the wire harness, which improves the fit between the wire harness and the branch pipe and enhances the fixing effect.

[0025] Please see Figure 1 As shown, in some embodiments, the rubber component further includes a lead tube 20, which is disposed on the side of the body 10 opposite to the outlet tube 30 and communicates with the cavity 100. It should be understood that the lead tube 20 provides a clear and independent channel for the wire harness to enter the cavity 100, allowing the wire harness to enter the body 10 in an orderly manner from the side opposite to the outlet tube 30, avoiding the messy problem caused by the wire harness randomly entering from the end face or side of the body 10, and improving the standardization of wire harness assembly. The lead tube 20 can guide and protect the wire harness entering the cavity 100, reducing friction between the wire harness and the edge of the body 10 during insertion, reducing the risk of wear on the wire harness sheath, and extending the service life of the wire harness. When the wire harness needs to be introduced from a distant location, the lead tube 20 can extend the entry path, preventing the wire harness from becoming loose or excessively bent before entering the cavity 100, ensuring a compact wire harness layout, and reducing interference with surrounding components.

[0026] In some embodiments, the structure in which the lead tube 20 communicates with the cavity 100 can be used in conjunction with a sealing element (not shown) to form a seal at the point where the wire harness enters. This seal works in conjunction with the sealing structure at the outlet to further block airflow inside and outside the cavity 100, enhance sound insulation, and improve overall waterproof and dustproof performance.

[0027] Please see Figure 2 As shown, in some embodiments, the lead-out pipe 30 includes a connecting branch pipe 33, which is located between the first branch pipe 31 and the second branch pipe 32, and connects the first branch pipe 31 and the second branch pipe 32 respectively. The connecting branch pipe 33 is connected to the main body 10, and an opening 330 is provided at the connection point. The opening 330 communicates with the cavity 100, and the area of ​​the opening 330 is larger than the cross-sectional area of ​​the lead-out pipe 20. It should be understood that the connecting branch pipe 33 connects the first branch pipe 31 and the second branch pipe 32 into one unit, and then connects to the main body 10 to form a stable frame. The opening 330 communicates directly with the cavity 100, and its area is larger than the cross-sectional area of ​​the lead-out pipe 20, providing more ample branching space for the wire harness entering the cavity 100 from the lead-out pipe 20. After the main wire harness enters the cavity 100, it can easily branch into the first branch pipe 31 and the second branch pipe 32 in the area of ​​the opening 330, avoiding branching jamming or wire harness compression due to narrow space, and improving assembly efficiency. The opening 330 has a larger cross-sectional area than the lead tube 20, which can accommodate multiple main wires branching out at the same time, or adapt to main wires with larger diameters branching out multiple branch lines, enhancing the adaptability to complex wire layouts.

[0028] Please see Figure 2 As shown, in some embodiments, the first branch pipe 31 includes a straight section 311 and a corrugated section 312. The corrugated section 312 is disposed at the end of the straight section 311 near the connecting branch pipe 33 and connects the straight section 311 and the connecting branch pipe 33 respectively. It should be understood that the corrugated section 312 has bendable characteristics, enabling the first branch pipe 31 to be adjusted at multiple angles between the straight section 311 and the connecting branch pipe 33, adapting to different spatial orientation requirements and solving the problem of restricted wire harness orientation caused by installation position deviation. During assembly, the wire exit direction of the straight section 311 can be quickly adjusted by bending the corrugated section 312, without the need for precise alignment of the installation position, reducing assembly difficulty and improving assembly efficiency. The straight section 311 maintains the stability of the wire harness exit and avoids wire harness compression caused by excessive bending, while the corrugated section 312 provides necessary flexible adjustment. The combination of the two makes the first branch pipe 31 both stable and flexible.

[0029] In some embodiments, the straight section 311 and the corrugated section 312 are integrally formed. In a vibrating environment (such as vehicle driving or mechanical operation), the corrugated section 312 can absorb vibration energy through its own deformation, reduce the tensile force of the wire harness caused by vibration, reduce the frictional loss between the wire harness and the inner wall of the branch pipe, and protect the integrity of the wire harness.

[0030] Please see Figure 2 As shown, in some embodiments, the extension direction of the lead tube 20 intersects with the extension direction of the second branch tube 32. In some embodiments, the extension directions of the lead tube 20, the second branch tube 32, and the first branch tube 31 intersect each other. It should be understood that the intersection of the extension directions of the lead tube 20 and the second branch tube 32, or the intersection of the lead tube 20, the first branch tube 31, and the second branch tube 32, allows the wire harness to enter and exit the rubber component from different spatial directions, avoiding the overlap of multiple wire harnesses in the same plane, achieving a three-dimensional layout of the wire harness in a limited space, and reducing the risk of mutual entanglement. The intersecting extension directions can guide the wire harness to disperse in different directions, so that the branch wire harness of the exit tube 30 is spatially staggered from the main wire harness of the inlet, especially in scenarios with dense surrounding components, which can reduce the cross-interference between wire harnesses and with external components. The staggered design allows for adaptation to different device wiring harness interface positions. For example, if the inlet and outlet ports have different installation directions on the device, the connection can be completed without additional bending of the wiring harness, reducing the risk of forced deformation during assembly. Furthermore, the multi-directional intersecting layout allows for more even stress distribution on the rubber components, reducing installation loosening or structural deformation caused by concentrated stress in one direction, and improving overall stability.

[0031] Please see Figure 2As shown, in this embodiment, the second branch pipe 32 is perpendicular to the extension direction of the lead pipe 20. Under the action of the corrugated section 312, the extension direction of the first branch pipe 31 is adjustable at the angle to the extension direction of the lead pipe 20, which increases flexibility and applicability.

[0032] Please see Figure 1 and Figure 2 As shown, in some embodiments, the body 10, lead tube 20, and outlet tube 30 are integrally molded structures. It should be understood that integral molding eliminates the seams between the body 10, lead tube 20, and outlet tube 30, forming a continuous and complete structure. This reduces stress concentration points caused by assembly and significantly improves the overall tear resistance and deformation resistance of the rubber parts, especially under long-term vibration or stress conditions, effectively reducing the risk of breakage. The seamless structure avoids air leakage or sound wave transmission at gaps, making the sound insulation effect of the cavity 100 more stable. Simultaneously, the integrally molded tube wall forms a continuous sealing barrier, improving waterproof and dustproof levels, making it suitable for harsh environments such as humid and dusty conditions. Integral molding completes the entire structure through a single injection molding or compression molding process, eliminating the need for component splicing and bonding processes, shortening the production cycle, and improving production efficiency. The one-piece molding process ensures the dimensional consistency of each component (such as the angle between the lead tube 20 and the outlet tube 30, the length of the branch tube, etc.), avoids assembly deviations caused by splicing errors, improves the compatibility accuracy with wire harnesses and peripheral equipment, and reduces the assembly rework rate.

[0033] Please see Figure 3 and Figure 4 As shown, in some embodiments, the inner wall of the lead tube 20 is provided with raised ribs 21, which are arranged around the circumference of the lead tube 20. It should be understood that the circumferential arrangement of the raised ribs 21 allows for multi-point contact with the outer sheath of the inserted wire harness. The elastic deformation of the rubber generates a radial clamping force, increasing the friction between the wire harness and the inner wall of the lead tube 20. This effectively prevents axial slippage of the wire harness during vibration or pulling, avoiding the risk of branch point displacement or interference due to wire harness loosening. The raised ribs 21 act as seals, tightly fitting against the surface of the wire harness to form multiple annular sealing lines. This further blocks the flow of air, moisture, or dust inside and outside the lead tube 20, working in conjunction with the overall sealing structure of the lead tube 20 to improve the waterproof and dustproof rating, making it suitable for harsher humid or dusty environments.

[0034] It is also important to understand that the circumferentially evenly distributed ribs 21 act as radial limiters for the inserted wire harness, preventing it from shifting to one side of the lead tube 20 due to gravity or assembly deviations. This ensures the wire harness enters the cavity 100 centered along the axial direction, providing a stable foundation for subsequent branching operations. The ribs 21 themselves are elastic, and in a vibrating environment, they can absorb some vibration energy through deformation, reducing rigid collisions between the wire harness and the tube wall, lowering the probability of wear on the wire harness sheath, and extending the wire harness's service life.

[0035] Please see Figure 1 As shown, in some embodiments, the outlet tube 30 has a slit 300 formed on the side opposite to the main body 10, and the slit 300 is provided along the extending direction of the outlet tube 30. It should be understood that by forming the slit 300 on the side of the outlet tube 30 opposite to the main body 10, the slit 300 serves as a mold removal channel, allowing the mold of the integrally molded rubber part to be removed from the slit 300, solving the problem of difficult demolding of complex structures; it should be noted that the slit 300 only serves as a mold channel and does not affect the overall structural strength of the rubber part. During the threading process, the direction of the wire harness branches can be observed to assist in threading and avoid the wire harness branches from being squeezed against the tube wall. When the ambient temperature changes, the outlet tube 30 and the wire harness will undergo dimensional changes due to thermal expansion and contraction. The slit 300 can absorb some stress by opening and closing, reducing the mutual compression between the tube body and the wire harness, and reducing the risk of tube body cracking or wire harness outer sheath damage.

[0036] Please see Figure 4 and Figure 5 As shown, in some embodiments, the rubber component further includes a transition portion 40, which is located between the main body 10 and the outlet tube 30, and connects the main body 10 and the outlet tube 30 respectively. The transition portion 40 encloses a transition space 400, which communicates with the cavity 100. The transition portion 40 gradually tapers from the main body 10 to the outlet tube 30. It should be understood that the gradual taper of the transition portion 40 from the main body 10 to the outlet tube 30 forms a smooth conical channel, allowing the wire harness to gradually converge as it enters the outlet tube 30 from the cavity 100, reducing sharp bends or right-angle bends, and lowering the risk of wear on the wire harness sheath. This is especially suitable for scenarios with multi-strand wire harness branches or thicker wire harnesses. The gradual taper design of the transition portion 40 disperses the stress at the connection between the main body 10 and the outlet tube 30, avoiding localized stress concentration caused by the difference in their diameters, improving the integrity and tear resistance of the one-piece molded structure, and extending the service life of the rubber component. The transition space 400 communicates with the cavity 100, and the tapered structure enhances the sound insulation effect.

[0037] Please see Figure 4 and Figure 5 As shown, in some embodiments, the outer periphery of the body portion 10 is provided with a mounting structure 110 for connecting the external structural member 50. It should be understood that the mounting structure 110 can be a groove. The body portion 10 connects to the external structural member 50 through the groove, ensuring the stability and sealing of the connection between the rubber component and the external structural member 50.
