Description

Technical Field

[0001] This utility model relates to the field of wire harness sheath technology, and in particular to a wire harness sheath with high sealing, high noise reduction and easy demolding. Background Technology

[0002] Traditional automotive firewall wiring harness sleeves use a double-seal design. Because the internal wiring harness has a large diameter, it can cause the wiring harness sleeve to shift, which can easily lead to seal failure.

[0003] Traditional automotive firewall wiring harness sheaths are designed with a hollow structure to ensure good noise reduction, but this makes it difficult to demold rubber products, resulting in low pass rates and low production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wire harness sheath that offers high sealing, high noise reduction, and easy demolding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire harness sheath with high sealing, high noise reduction and easy demolding includes a sealing sheath and a first outlet at the top of the sealing sheath. A groove is opened at the bottom of the outer ring of the sealing sheath, and a sealing mechanism including a sealing ring and a sealing rib is provided in the groove. The sealing sheath on both sides of the first outlet has symmetrical openings.

[0007] A sealing ring is provided on the side of the card slot near the first outlet, a sealing ring is provided at the top of the side of the card slot away from the first outlet, and a sealing rib is provided at the center of the bottom end of the card slot.

[0008] It also includes a mounting ring, the diameter of which is adapted to the inner diameter of the first outlet.

[0009] Preferably, the bottom of the sealing sleeve is provided with a second outlet, and the inner wall of the second outlet is provided with a first gasket.

[0010] Preferably, the sealing sleeve has a hollow cavity at its center, which is connected to the first outlet and the second outlet respectively.

[0011] Preferably, a second washer is fixedly connected to the inner wall of the mounting ring, and the second washer has the same structure as the first washer.

[0012] Preferably, symmetrical mounting blocks are fixedly connected to both sides of the mounting ring, the shape of the mounting blocks is adapted to the opening, and the two sides of the mounting blocks are provided with connecting grooves.

[0013] Preferably, fixing blocks are fixedly connected to both sides of the top end of the mounting ring, and the bottom ends of the two fixing blocks are fixedly connected to the two mounting blocks respectively.

[0014] Preferably, the fixing block has two injection holes that communicate with the connecting groove, and waterproof wings are fixedly connected to the opposite sides of the two mounting blocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model improves the sealing performance of the sealing sleeve by setting up a sealing mechanism. In addition to the traditional sealing ring and sealing ring, a third seal, namely the sealing rib, is added. The sealing rib is generated in the form of a rounded corner with a raised radius of 0.3 mm, which improves the sealing performance of the sealing sleeve and indirectly enhances the noise reduction function.

[0017] This invention, by setting an opening, provides the sealing sleeve with greater expansion space during the demolding process of manufacturing the sealing sleeve, which facilitates the sealing sleeve's separation from the mold core, achieving easy demolding and improving production efficiency and yield.

[0018] This utility model, by setting up an installation ring and an installation block, uses the installation ring in conjunction with the sealing sleeve. After the wire harness passes through the sealing sleeve, the opening is sealed by the installation ring and the installation block, ensuring a closed loop at the opening. This achieves the effect of hollow sound insulation and noise reduction, effectively reducing the noise transmitted into the vehicle. It also fixes the installation block and installation ring together with the sealing sleeve, ensuring the stability of the sealing sleeve during normal operation. The waterproof wing can be used for limiting and preventing detachment, improving the sealing effect, and preventing water ingress. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 A wire harness sheath with high sealing, high noise reduction and easy demolding includes a sealing sheath 1 and a sealing rib 7. The top of the sealing sheath 1 is provided with a first outlet 2. The bottom of the outer ring of the sealing sheath 1 is provided with a groove 4. A sealing mechanism 41 including a sealing ring 6 and a sealing rib 7 is provided in the groove 4. The sealing sheath 1 on both sides of the first outlet 2 is symmetrically provided with openings 9.

[0027] A sealing ring 6 is provided on the side of the slot 4 near the first outlet 2, a sealing ring 5 is provided at the top of the side of the slot 4 away from the first outlet 2, and a sealing rib 7 is provided at the center of the bottom end of the slot 4.

[0028] It also includes a mounting ring 10, the diameter of which is adapted to the inner diameter of the first outlet 2. The sealing sleeve 1 is a rubber part used for installing automotive firewall wiring harnesses. After the wiring harness is installed, the sealing sleeve 1 is fastened to the automotive sheet metal part through the slot 4. The sealing mechanism 41 retains the traditional sealing ring 6 and sealing ring 5, and adds a third seal, namely the sealing rib 7. The sealing rib 7 is generated in the form of a raised radius of 0.3 mm rounded corner, which improves the sealing performance of the sealing sleeve 1 and indirectly improves the noise reduction function. Since the sealing sleeve 1 is large at both ends and small in the middle, it must pass through the small end during demolding, which increases the demolding difficulty. Openings 9 are opened on both sides of the sealing sleeve 1, which gives the sealing sleeve 1 more expansion space during the demolding process of manufacturing and production, which is conducive to the sealing sleeve 1 detaching from the mold core and achieving easy demolding, improving production efficiency and pass rate. The mounting ring 10 is used in conjunction with the sealing sleeve 1. After the wiring harness passes through the sealing sleeve 1, the mounting ring 10 and the mounting block 14 seal the opening 9 to ensure that the opening 9 is closed, achieving the effect of hollow sound insulation and noise reduction, effectively reducing the noise transmitted into the vehicle.

[0029] As a technical optimization of this utility model, the sealing sleeve 1 is provided with a second outlet 3 at the bottom, and a first washer 31 is provided on the inner wall of the second outlet 3. The second outlet 3 and the first outlet 2 are used for the wire harness to pass through, and the first washer 31 can be squeezed and deformed against the outer wall of the wire harness, so that the sealing sleeve 1 is tightly connected to the wire harness.

[0030] As a technical optimization of this utility model, a hollow cavity 8 is formed in the center of the sealing sleeve 1, and the hollow cavity 8 is connected to the first outlet 2 and the second outlet 3 respectively. The hollow cavity 8 is used to achieve a hollow sound insulation effect.

[0031] As a technical optimization of this utility model, a second washer 11 is fixedly connected to the inner wall of the mounting ring 10. The second washer 11 has the same structure as the first washer 31. The second washer 11 also has the same function as the first washer 31.

[0032] As a technical optimization of this utility model, symmetrical mounting blocks 14 are fixedly connected to both sides of the mounting ring 10. The shape of the mounting blocks 14 is adapted to the opening 9, and the two sides of the mounting blocks 14 are provided with connecting grooves 15. When installing the wire harness, the mounting blocks 14 are connected to the opening 9, so that the mounting blocks 14 fill the opening 9, thereby achieving the overall sealing of the sealing sleeve 1. At this time, the connecting grooves 15 are located on both sides of the inner wall of the opening 9 and form two channels with the inner wall of the opening 9.

[0033] As a technical optimization of this utility model, fixing blocks 12 are fixedly connected to both sides of the top of the mounting ring 10, and the bottom ends of the two fixing blocks 12 are fixedly connected to the two mounting blocks 14 respectively. The mounting ring 10 and the two mounting blocks 14 are connected into a whole by the fixing blocks 12, and the whole can be directly installed in the opening 9 and the first outlet 2 of the sealing sleeve 1 during use.

[0034] As a technical optimization of this utility model, the fixing block 12 has two injection holes 13 that communicate with the connecting groove 15, and the two mounting blocks 14 are fixedly connected to the opposite sides with waterproof wings 16. When the mounting block 14 and the mounting ring 10 are installed as a whole in the opening 9 and the first outlet 2 of the sealing sleeve 1, the bottom end of the waterproof wing 16 abuts against the outer wall of the sealing sleeve 1, which can be used to limit the detachment, improve the sealing effect, and prevent water ingress. After installation, sealant is injected into the two channels formed by the connecting groove 15 and the inner wall of the opening 9 through the injection holes 13, so that the sealing at the opening 9 is guaranteed, and the mounting block 14 and the mounting ring 10 are fixedly connected to the sealing sleeve 1 as a whole, and the stability of the sealing sleeve 1 is guaranteed when it is working normally.

[0035] In use, during the manufacturing and demolding process, the opening 9 provides greater expansion space for the sealing sleeve 1. When installing the wire harness, the mounting block 14 is connected to the opening 9, and the mounting ring 10 is connected to the first outlet 2, so that the mounting block 14 fills the opening 9, and the bottom end of the waterproof wing 16 abuts against the outer wall of the sealing sleeve 1. At this time, the connecting groove 15 is located on both sides of the inner wall of the opening 9 and forms two channels with the inner wall of the opening 9. The wire harness is passed through the mounting ring 10 and the second outlet 3 for tight installation. After installation, sealant is injected into the two channels formed by the connecting groove 15 and the inner wall of the opening 9 through the injection hole 13. After the sealant hardens, the sealing sleeve 1 is fastened to the automotive sheet metal part through the slot 4. At this time, the sealing ring 5, sealing ring 6 and sealing rib 7 are fastened to the reserved positions on the sheet metal part, and the installation is completed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
