Technical Field

[0001] This utility model belongs to the field of wire harness protection technology, specifically relating to a sealing sleeve for automotive wire harnesses. Background Technology

[0002] As the core carrier of vehicle circuitry, automotive wiring harnesses bear the key functions of power transmission and signal control. The core function of automotive wiring harness sealing sleeves is to protect the wiring harness from external environmental damage, such as high temperatures, oil, and chemicals. They also provide waterproofing and dustproofing, preventing short circuits or corrosion and ensuring the safe operation of the electrical system. However, existing automotive wiring harness sealing sleeves often use a full-line wrapping method to protect the wiring harness. When a fault occurs, it is difficult to accurately locate the fault point. Furthermore, the sealing sleeve needs to be removed during maintenance, resulting in a sealing gap and affecting its sealing effect in subsequent use. Utility Model Content

[0003] The purpose of this utility model is to provide a sealing sleeve for automotive wiring harnesses, which adopts a segmented design. Each segment of the sealing sleeve is connected by a quick-connect structure, which makes it easy to disconnect the connection between the segments of the sealing sleeve during maintenance, making it easier to find the fault point of the wiring harness. Moreover, the sealing sleeves that are reconnected after maintenance will not have sealing defects and are more durable.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A sealing sleeve for automotive wiring harnesses includes a segmented sealing sleeve, with quick-connect assemblies installed at both ends of the segmented sealing sleeve.

[0006] A quick-connect assembly includes a quick connector, which is fixed to both ends of a segmented sealing sleeve. One end of the quick connector is fixed with a plurality of quick-connect blocks, which are L-shaped. One end of the quick connector is also provided with a plurality of quick-connect slots, the shape of the entrance of the quick-connect slots being the same as that of one end of the quick-connect blocks. The interior of the quick-connect slots has a groove for locking one end of the quick-connect blocks.

[0007] The quick connector has threads on its outer side, and one of the quick connectors is threaded to a reinforcing swivel sleeve, which is used to fix two connected quick connectors.

[0008] Furthermore, a first rotating ring is rotatably mounted on the outer side of one end of the quick connector, and a first sealing ring is fixed to one end of the first rotating ring.

[0009] Furthermore, a second rotating ring is rotatably mounted on the inner side of one end of the quick connector, and a second sealing sleeve is fixed to one end of the second rotating ring.

[0010] Furthermore, the segmented sealing sleeve includes an inner sealing sleeve, and both ends of the inner sealing sleeve are provided with outer sealing sleeves. One end of the outer sealing sleeve is fixed to one end of the quick connector, and the inner diameter of the outer sealing sleeve is larger than the inner diameter of the inner sealing sleeve.

[0011] Furthermore, a tightening band is provided on the outer side of the expanding sealing sleeve.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model uses a split design with segmented sealing sleeves that are linked with quick connectors, quick connector blocks, quick connector slots, and reinforcing rotating sleeves to achieve quick installation and disassembly between the two segmented sealing sleeves. At the same time, the reinforcing rotating sleeve can provide secondary fixation to the connection between the quick connector blocks and quick connector slots, further strengthening the connection between the two quick connectors and preventing accidental detachment. In addition, the split structure allows for partial disassembly and maintenance, making it easy to quickly locate fault points, and the sealing performance is not affected after maintenance.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1 to 5 As shown, a sealing sleeve for automotive wiring harnesses includes a segmented sealing sleeve 1, with quick-connect assemblies 2 installed at both ends of the segmented sealing sleeve 1.

[0023] The quick-connect assembly 2 includes a quick connector 21, which is fixed to both ends of the segmented sealing sleeve 1. One end of the quick connector 21 is fixed with a plurality of quick-connect blocks 22, which are L-shaped. One end of the quick connector 21 is also provided with a plurality of quick-connect slots 23. The shape of the entrance of the quick-connect slot 23 is the same as that of one end of the quick-connect block 22. The interior of the quick-connect slot 23 has a groove for locking one end of the quick-connect block 22.

[0024] The quick connector 21 has threads on its outer side, and one of the quick connectors 21 is connected to a reinforcing swivel sleeve 3 on its outer side. The reinforcing swivel sleeve 3 is used to fix two connected quick connectors 21.

[0025] As described above, the quick-connect plug 22 and quick-connect slot 23 cooperate to enable quick alignment and connection between two quick connectors 21, thereby achieving quick installation and disassembly between multiple segmented sealing sleeves 1. After the quick-connect plug 22 is inserted into the quick-connect slot 23, it can be rotated at a certain angle to make one end of the quick-connect plug 22 lock into the slot inside the quick-connect slot 23 to prevent it from coming out. The quick-connect plugs 22 on the two quick connectors 21 are locked into the quick-connect slot 23 of the other quick connector 21 to achieve bidirectional fixation. After the fixation is completed, the reinforcing rotating sleeve 3 installed on the outside of one of the quick connectors 21 is rotated to move the reinforcing rotating sleeve 3 between the two connected quick connectors 21 to achieve secondary fixation of the two quick connectors 21. Since the quick-connect plug 22 can only rotate within the quick-connect slot 23, even if the quick-connect plug 22 comes out of the slot at one end of the quick-connect slot 23 after being reinforced by the reinforcing rotating sleeve 3, it will not cause the two quick connectors 21 to become disconnected.

[0026] Furthermore, the segmented sealing sleeve 1 with its split design allows for quicker location of the fault point when the wiring harness malfunctions by separating each segmented sealing sleeve 1, facilitating repair. After repair, the protective performance of each segmented sealing sleeve 1 will not be compromised when reconnected.

[0027] Please refer to the following: Figure 4 and Figure 5 As shown, a first rotating ring 25 is rotatably mounted on the outer side of one end of the quick connector 21, and a first sealing ring 24 is fixed to one end of the first rotating ring 25. A second rotating ring 27 is rotatably mounted on the inner side of one end of the quick connector 21, and a second sealing sleeve 26 is fixed to one end of the second rotating ring 27.

[0028] As described above, after being fixed between the two quick connectors 21, the two first sealing rings 24 and the two second sealing sleeves 26 located on the two quick connectors 21 are respectively bonded together to achieve a sealing effect. At the same time, when used in conjunction with the first rotating ring 25 and the second rotating ring 27, the two first sealing rings 24 and the two second sealing sleeves 26 can still rotate on the quick connector 21 after they are bonded together. This avoids the two first sealing rings 24 and the two second sealing sleeves 26 being subjected to torsional force after being pressed together and then rotated, which would cause them to break. This ensures that the sealing effect remains effective.

[0029] Please refer to it again. Figure 3 As shown, the segmented sealing sleeve 1 includes an inner sealing sleeve 11, with an outer sealing sleeve 12 at both ends of the inner sealing sleeve 11. One end of the outer sealing sleeve 12 is fixed to one end of the quick connector 21. The inner diameter of the outer sealing sleeve 12 is larger than the inner diameter of the inner sealing sleeve 11. A tightening band 13 is provided on the outer side of the outer sealing sleeve 12.

[0030] In the above, when the wiring harness needs to be repaired, the quick-connect assembly 2 can be slid directly towards the middle of the inward sealing sleeve 11, so that the segmented sealing sleeve 1 folds outward from the outward expanding sealing sleeve 12, thereby exposing the wiring inside. The inner diameter of the outward expanding sealing sleeve 12 is larger than that of the inward closing sealing sleeve 11, so that the inward closing sealing sleeve 11 can be folded outward from the outward expanding sealing sleeve 12. The tightening band 13 installed on the outside of the outward expanding sealing sleeve 12 can tighten the outward expanding sealing sleeve 12, so that the outward expanding sealing sleeve 12 can also completely cover the wiring harness of the car, just like the inward closing sealing sleeve 11.

[0031] The working principle of this utility model is as follows: Two quick-connect components 2 can be engaged by rotating the quick-connect plug 22 and quick-connect slot 23 at a certain angle, and then disengaged by rotating them in the opposite direction at a certain angle, thereby completing the quick connection between the two quick connectors 21. At the same time, the reinforcing rotating sleeve 3 installed on the outside of one of the quick connectors 21 rotates after the two quick connectors 21 are connected, so that the reinforcing rotating sleeve 3 is between the two quick connectors 21, and it is reinforced for a second time, thereby completing the fixation between the two quick-connect components 2. This allows the two segmented sealing sleeves 1 to be quickly assembled and disassembled. At the same time, the two first sealing rings 24 and the two second sealing sleeves 26 set between the two quick connectors 21 after installation will fit together to achieve a sealing effect at the connection. When it is necessary to repair the wire harness, the connection between the two quick connectors 21 can be disconnected, and the quick connector 21 can be pulled towards the middle of its corresponding inner sealing sleeve 11. The quick connector 21 will drive the quick-connect plug 22 connected to it to move together, and the quick-connect plug 22 and the quick connector 21 will fold outward to expose the internal wire harness, thereby completing the repair of the wire harness.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
