[0017] Example: Figs. 1-3As shown, this utility model provides an automotive wiring harness sealing sleeve, including a housing 1. A fastening mechanism 2 is fixedly provided on the outer side of the housing 1, a connecting wire 4 is provided on the inner side of the housing 1, and a protective mechanism 3 is provided on the outer side of the connecting wire 4. The fastening mechanism 2 includes two fixing plates 23, which are respectively fixedly connected to both sides of the housing 1. Fixing bolts 21 are inserted into the lower surface of the fixing plates 23. A sealing ring 24 is fixedly provided on the upper surface of the housing 1. An interface 20 is fixedly provided at the upper end of the connecting wire 4, and multiple connection ports 26 are fixedly provided at the upper end of the interface 20. During the installation of the automotive wiring harness sealing sleeve, the fastening mechanism 2 first secures the housing 1... Place the device in the designated installation position, ensuring that the two fixing plates 23 are tightly fitted to the installation surface. Then, pass the fixing bolts 21 through the fixing holes 22 and tighten the fixing bolts 21 with a tool to firmly fix the outer shell 1 to the installation surface. During this process, the fixed connection design between the fixing plates 23 and the outer shell 1 ensures the reliability of the fastening. At the same time, after the sealing ring 24 on the upper surface of the outer shell 1 is installed, it can effectively prevent external factors such as moisture and dust from seeping in from the installation gap, enhancing the sealing performance of the sealing sleeve. Through this fastening method, the stability and safety of the connecting wire 4 and its interface 20 are ensured after installation.
[0018] Both sides of the outer shell 1 are fixed with multiple anti-slip textures 27 distributed at equal intervals. The lower surface of the fixing plate 23 is provided with fixing holes 22. The inner side of the fixing holes 22 is slidably fitted with the fixing bolts 21. The upper surface of the outer shell 1 is provided with multiple connecting grooves 25. The inner side of the connecting grooves 25 is fitted with the connecting ports 26. After the sealing ring 24 on the upper surface of the outer shell 1 is installed in place, it can effectively prevent external factors such as moisture and dust from seeping in from the installation gap, thereby enhancing the sealing performance of the sealing sleeve.
[0019] The protection mechanism 3 includes a crack-resistant base 31, the inner side of which is fixedly connected to one end of the connecting wire 4. A protective spring 30 is fixedly installed at the lower end of the crack-resistant base 31, with the inner side of the protective spring 30 fitting against the outer side of the connecting wire 4. A sealing ring 33 is installed at the upper end of the crack-resistant base 31, with the inner side of the sealing ring 33 fitting against the outer side of the interface 20. Through the protection mechanism 3, when installing the automotive wiring harness sealing sleeve, one end of the connecting wire 4 is first fixedly connected to the inner side of the crack-resistant base 31. The crack-resistant base 31 is made of rubber, which has good elasticity and crack resistance, and can effectively absorb and disperse the impact force from the outside, protecting the connecting wire 4 from damage. Next, the protective spring 30 is installed at the lower end of the crack-resistant base 31. The inner side of the protective spring 30 is tightly fitted with the outer side of the connecting wire 4, further enhancing the stability and bending resistance of the connecting wire 4. In addition, the sealing ring 33 at the upper end of the crack-resistant base 31 fits with the outer side of the interface 20 through the sealing port 32 opened on its inner side, forming another sealing barrier, effectively preventing moisture, dust and other impurities from entering the interior of the interface 20, ensuring the cleanliness of the connection port 26 and the reliability of the electrical connection. Through such a protective mechanism 3 design, the service life of the connecting wire 4 and its interface 20 is greatly extended, and the overall safety of the automotive electrical system is improved.
[0020] The crack-resistant base 31 has multiple bending grooves 34 arranged in a ring array on its outer side. The upper end of the sealing ring 33 has a sealing port 32. The inner side of the sealing port 32 fits against the outer side of the interface 20. The crack-resistant base 31 is a rubber base. The crack-resistant base 31 is made of rubber material, which has good elasticity and crack resistance. It can effectively absorb and disperse the impact force from the outside. The sealing ring 33 at the upper end of the crack-resistant base 31 fits against the outer side of the interface 20 through the sealing port 32 opened on its inner side, forming another sealing barrier. This effectively prevents moisture, dust and other impurities from entering the interior of the interface 20, ensuring the cleanliness of the connection port 26 and the reliability of the electrical connection.
[0021] Working principle: During the installation of the automotive wiring harness sealing sleeve, the fastening mechanism 2 first places the outer shell 1 into the predetermined installation position, ensuring that the two fixing plates 23 are tightly fitted with the installation surface. Then, the fixing bolts 21 are passed through the fixing holes 22 and tightened with tools, thereby firmly fixing the outer shell 1 to the installation surface. In this process, the fixed connection design between the fixing plates 23 and the outer shell 1 ensures the reliability of the fastening. At the same time, after the sealing ring 24 on the upper surface of the outer shell 1 is installed, it can effectively prevent moisture, dust and other external factors from seeping in from the installation gap, enhancing the sealing performance of the sealing sleeve. Through this fastening method, the stability and safety of the connecting wire 4 and its interface 20 after installation are ensured.
[0022] With the protection mechanism 3, when installing the automotive wiring harness sealing sleeve, one end of the connecting wire 4 is first fixedly connected to the inner side of the crack-resistant base 31. The crack-resistant base 31 is made of rubber, which has good elasticity and crack resistance, and can effectively absorb and disperse the impact force from the outside, protecting the connecting wire 4 from damage. Next, the protective spring 30 is installed at the lower end of the crack-resistant base 31. The inner side of the protective spring 30 is tightly fitted to the outer side of the connecting wire 4, further enhancing the stability and bending resistance of the connecting wire 4. In addition, the sealing ring 33 at the upper end of the crack-resistant base 31 fits against the outer side of the interface 20 through the sealing port 32 opened on its inner side, forming another sealing barrier, effectively preventing moisture, dust and other impurities from entering the interior of the interface 20, ensuring the cleanliness of the connection port 26 and the reliability of the electrical connection. Through this protection mechanism 3 design, the service life of the connecting wire 4 and its interface 20 is greatly extended, and the overall safety of the automotive electrical system is improved.
