Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and more specifically, to a novel rubber shell for automobiles. Background Technology

[0002] Rubber stretch shells for automotive wiring harnesses are essential components specifically designed to protect automotive wiring harnesses. They are typically made of highly elastic rubber. This rubber can stretch within a certain range to accommodate wiring harnesses of different lengths and shapes, tightly wrapping around the harness and providing comprehensive protection.

[0003] When using a rubber stretch shell for automotive wiring harnesses, if the internal wiring harness lacks a limiting mechanism, the harness may move relative to the vehicle within the shell. Under vibration and bumps during vehicle operation, the connectors of the harness may loosen due to frequent movement. Furthermore, the free movement of the harness within the shell can easily cause friction with the inner wall of the shell and other wiring harnesses. Over time, this can lead to accelerated wear of the wiring harness's insulation layer and a reduced lifespan. Therefore, a new type of automotive rubber shell with a built-in limiting mechanism is needed to solve these problems. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a novel rubber housing for automobiles. This solution includes a limiting component in a stretchable rubber outer shell. The limiting component is wrapped around the outside of multiple power wires by an elastic thickened surface layer with built-in deformable steel wire strips, thus fitting and wrapping the outside of the power wires and helping to extend the service life of the wiring harness.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A novel rubber housing for automobiles includes a stretchable rubber outer shell. Side expansion plugs are symmetrically fixedly connected to the front and rear ends of the stretchable rubber outer shell. Multiple power wires pass through the inner ends of the side expansion plugs and are arranged in parallel. A limiting component is fixedly connected to the inner end of the side expansion plugs. The limiting component is wound around the outer side of the multiple power wires. The limiting component includes an elastic thickened surface layer. A pair of deformable steel wire strips are fixedly connected to the inner end of the elastic thickened surface layer and are arranged symmetrically from left to right.

[0007] Furthermore, the outer end of the side expander is fixedly connected with a protruding thread, and the side expander is engaged with the automotive accessory mounting hole through the protruding thread.

[0008] Furthermore, both the upper and lower ends of the elastic thickened surface layer are fixedly connected to a breathable outer layer, and the input ends of multiple power cords are electrically connected to electrical connectors.

[0009] Furthermore, a rubber engaging outer ring is fixedly connected to one end of the limiting component near the electrical connector, and the rubber engaging outer ring is sleeved on the outside of the electrical connector.

[0010] Furthermore, a tension spring is provided at the lower end of the rubber engagement outer ring, and a partition opening is fixedly connected between the left and right inner walls of the tension spring.

[0011] Furthermore, an anti-slip inner liner is fixedly connected to the inner wall of the rubber engagement outer ring, and the rubber engagement outer ring is engaged with the outer side of the electrical connector through the anti-slip inner liner.

[0012] Furthermore, the inner wall of the stretchable rubber outer shell is provided with a waterproof inner layer, and the outer wall of the stretchable rubber outer shell is provided with a friction-resistant outer layer.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) This solution sets a limiting component in the stretchable rubber outer shell. The limiting component is wrapped around the outside of multiple power wires by the elastic thickened surface layer of the built-in deformable steel wire strip, and the outside of the power wires is fitted and wrapped. The limiting component is made of deformable material, which can be adapted to power wires of different dimensions. It can effectively fix the position of the power wires in the stretchable rubber outer shell, which can greatly reduce the risk of loosening of the wire harness connector, reduce the wear of the insulation layer, and help extend the service life of the wire harness.

[0015] (2) A rubber engaging outer ring is provided at the connection between the limiting component and the electrical connector. The rubber engaging outer ring can engage with the electrical connector to make the limiting component stably set on the outside of the overall wire harness. The rubber engaging outer ring is provided with a tension spring at the partition opening below it. The tension spring can make the dimensions of the rubber engaging outer ring change flexibly, so that it can be adapted to electrical connectors of different sizes. The anti-slip inner liner in the rubber engaging outer ring can improve the tightness of the connection between the rubber engaging outer ring and the outer wall of the electrical connector, making it less likely to loosen.

[0025] Example:

[0026] Please see Figure 1-4A novel rubber shell for automobiles includes a stretchable rubber outer shell 3. Side expansion plugs 1 are symmetrically fixedly connected to the front and rear ends of the stretchable rubber outer shell 3. Multiple power wires 4 pass through the inner end of the side expansion plugs 1. The multiple power wires 4 are arranged in parallel. A limiting component 5 is fixedly connected to the inner end of the side expansion plugs 1. The limiting component 5 is wound around the outer side of the multiple power wires 4. The limiting component 5 includes an elastic thickened surface layer 8. A pair of steel wire deformable strips 10 are fixedly connected to the inner end of the elastic thickened surface layer 8. The two steel wire deformable strips 10 are arranged symmetrically from left to right.

[0027] Please see Figure 2-4 The outer end of the side expansion plug 1 is fixedly connected with a protruding thread 2. The side expansion plug 1 is engaged with the automotive parts mounting hole through the protruding thread 2. Both the upper and lower ends of the elastic thickened surface layer 8 are fixedly connected with a breathable outer layer 9. The input ends of multiple power wires 4 are electrically connected with an electrical connector 7. The end of the limiting component 5 near the electrical connector 7 is fixedly connected with a rubber engaging outer ring 6. The rubber engaging outer ring 6 is sleeved on the outside of the electrical connector 7. The lower end of the rubber engaging outer ring 6 is provided with a tension spring 11. The left and right inner walls of the tension spring 11 are fixedly connected with a partition opening 12. The inner side wall of the rubber engaging outer ring 6 is fixedly connected with an anti-slip inner liner 13. The rubber engaging outer ring 6 is engaged with the outside of the electrical connector 7 through the anti-slip inner liner 13. The inner side wall of the stretchable rubber outer shell 3 is provided with a waterproof inner layer 14. The outer side wall of the stretchable rubber outer shell 3 is provided with a friction-resistant outer layer 15.

[0028] Please see Figure 1-4This solution provides physical protection for the automotive wiring harness by having the power conductor 4 pass through the inside and outside of the stretchable rubber outer shell 3. The side expansion plug 1 is engaged with the automotive accessory mounting hole via the protruding thread 2, ensuring the stable placement of the power conductor 4 within the stretchable rubber outer shell 3 and preventing damage from external wear, scratches, and impacts. Furthermore, a limiting component 5 is installed within the stretchable rubber outer shell 3. This limiting component 5, through the elastic thickened surface layer 8 of the built-in deformable steel wire strip 10, wraps around the outside of multiple power conductors 4, tightly encasing them. The use of deformable material to form the limiting component 5 allows it to adapt to power conductors 4 of different dimensions, effectively fixing the position of the power conductor 4 within the stretchable rubber outer shell 3. This significantly reduces the risk of loose wiring harness connectors and minimizes insulation wear, thus extending the lifespan of the wiring harness. Simultaneously, the elastic thickened surface layer 8 further enhances the protection. The thick layer 8 is provided with breathable outer layers 9 on the top and bottom. The breathable outer layers 9 can dissipate the heat of the power cord 4 during operation, improving the functionality of the elastic thickened layer 8. The connection between the limiting component 5 and the electrical connector 7 is provided with a rubber engaging outer ring 6. The rubber engaging outer ring 6 can engage with the electrical connector 7 to stably position the limiting component 5 on the outside of the overall wire harness. The rubber engaging outer ring 6 is provided with a tension spring 11 in the partition opening 12 below it. The tension spring 11 can flexibly change the dimension of the rubber engaging outer ring 6 to adapt to electrical connectors 7 of different sizes. The rubber engaging outer ring 6 is provided with an anti-slip inner liner 13 to improve the tightness of the connection between the rubber engaging outer ring 6 and the outer wall of the electrical connector 7, making it less likely to loosen. When the protruding thread 2 is in use, the waterproof inner layer 14 on the inside and the abrasion-resistant outer layer 15 on the outside can improve the service life and functionality of the stretchable rubber outer shell 3.
