Description

Technical Field

[0001] This utility model relates to the field of electrical wiring harness installation technology, and in particular to a sealed installation device. Background Technology

[0002] Wiring harnesses are commonly used electrical products. In some usage scenarios, it is often necessary to pass the wiring harness through the floor or wall. How to ensure the sealing performance after the hole is passed is a crucial issue, especially when the wiring harness passes through the floor of a motorhome. If the floor cannot be properly sealed after the hole is passed, it will not only cause the vehicle to be noisy, but may even cause water to enter the vehicle, affecting the user experience.

[0003] Existing technologies offer two solutions to address the aforementioned problems. One method involves interlocking a rubber component with a sheet metal component. A hole is made in the center of the rubber component for the wire harness to pass through. The upper and lower annular lips of the rubber component clamp the sheet metal component and achieve a fixed and sealed fit. However, this type of rubber component is only suitable for thin-walled sheet metal components, which has significant limitations. The other method involves directly filling the perforation with expanding foam and curing it to form a primary sealing layer. Although this method provides better sealing, it lacks a supporting structure, resulting in poor stability of the wire harness. It is also inconvenient to disassemble, increasing the difficulty of maintenance.

[0004] Therefore, a sealed installation device is needed to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a sealing installation device, which includes a support structure 10, a first sealing structure 20, a second sealing structure, and a locking member 30. The support structure 10 has a through hole 11 for threading a wire harness 100 and can be threaded onto a mounting plate 200. The first sealing structure 20 is connected to the support structure 10 and has a through hole 21 communicating with the through hole 11. The first sealing structure 20 seals against the first end face of the mounting plate 200. The second sealing structure is sealed between the inner wall of the through hole 11 and / or the inner wall of the through hole 21 and the outer peripheral surface of the wire harness 100. The locking member 30 is detachably connected to the support structure 10, and the locking member 30 abuts against the second end face of the mounting plate 200. The first end face and the second end face are parallel.

[0036] Specifically, in this embodiment, as Figure 2As shown, the mounting plate 200 is provided with mounting holes 201, and the support structure 10 passes through the mounting holes 201. The through holes 21 and the wire holes 11 can pass through the wire harness 100. The first sealing structure 20 is sealed against the first end face of the mounting plate 200. The locking member 30 and the support structure 10 are detachably connected, and the locking member 30 can abut against the second end face of the mounting plate 200, thereby stably connecting the support structure 10 to the mounting plate 200. The support structure 10 can provide sufficient support for the wire harness 100, thereby improving the stability of the wire harness 100, extending the service life of the wire harness 100, and preventing the sealing installation device from collapsing. The first sealing structure 20 and the locking member 30 can abut against the two end faces of the mounting plate 200 respectively, thereby enabling the sealing installation device to have good versatility and adapt to mounting plates 200 of different thicknesses, improving the flexibility of use. The setting of the first sealing structure 20 and the second sealing structure can also improve the sealing performance of the sealing installation device, thereby ensuring the safety of the wire harness 100.

[0037] Furthermore, such as Figure 1 As shown, at least a portion of the outer peripheral surface of the support structure 10 is provided with external threads, and the inner ring of the locking member 30 is provided with internal threads. The internal and external threads are configured to cooperate. Specifically, in this embodiment, the support structure 10 is a cylindrical structure, with a portion of its outer peripheral structure provided with external threads, and the inner ring of the locking member 30 is provided with internal threads. The internal and external threads are configured to cooperate, allowing the locking range formed by the support structure 10 and the locking member 30 to be adjustable, thereby improving the versatility of the sealing installation device. Furthermore, the support structure 10 and the locking member 30 are threadedly connected, making them convenient to use and providing a stable connection.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the sealing installation device also includes fasteners. The locking member 30 includes a locking portion 31 and a flange 32. The flange 32 surrounds the periphery of the locking portion 31, and the fastener passes through the flange 32 to connect the locking member 30 to the mounting plate 200. Specifically, in this embodiment, by connecting the fastener to the mounting plate 200 after it passes through the flange 32, the locking member 30 can be connected to the mounting plate 200. At the same time, the locking member 30 is connected to the support structure 10, which further improves the stability of the connection between the support structure 10 and the mounting plate 200, ensuring the support effect of the support structure 10 while ensuring the sealing effect between the sealing installation device and the mounting plate 200.

[0039] Furthermore, such as Figure 1 and Figure 2As shown, the fastener is a self-tapping screw 40. The flange 32 has a through hole, through which the self-tapping screw 40 passes and connects to the mounting plate 200. Specifically, in this embodiment, this arrangement ensures that when the sealing mounting device is installed on mounting plates 200 of different thicknesses, the fastener can always prevent loosening of the locking member 30, thereby improving the stability of the connection between the flange 32 and the mounting plate 200, enhancing safety performance during use, and providing convenient and efficient installation.

[0040] Alternatively, in another embodiment, the fastener is a bolt, the flange 32 has a through hole, and the mounting plate 200 has a threaded hole. The bolt passes through the through hole and is threaded into the threaded hole. The through hole is a slotted hole, which ensures that the through hole and the corresponding threaded hole can always be connected when the sealing device is installed on mounting plates 200 of different thicknesses, thereby ensuring the normal safety of the bolt. This also improves the convenience of disassembly and assembly, and enhances the stability of the connection between the flange 32 and the mounting plate 200, ensuring its performance.

[0041] Alternatively, in other embodiments, the fastener can also be a locking pin. The mounting plate 200 has a pin hole, and the locking pin passes through the through hole and engages with the pin hole to achieve the same effect. No specific limitation is made here.

[0042] Furthermore, multiple fasteners are provided, and these fasteners are spaced apart around the periphery of the flange 32. Specifically, in this embodiment, multiple fasteners are provided, and these multiple fasteners are spaced equally around the periphery of the flange 32, which can improve the stress balance of the flange 32, thereby ensuring the installation stability of the support structure 10, ensuring the support effect on the wire harness 100, and further improving the stability of the wire harness 100 during use.

[0043] Furthermore, such as Figure 2 As shown, the locking part 31 and the flange 32 are stepped, and the end face of the locking part 31 facing the mounting plate 200 and the end face of the flange 32 facing the mounting plate 200 are on the same plane. Specifically, in this embodiment, the height of the flange 32 is lower than the height of the locking part 31. This arrangement ensures the thread length of the locking part 31, thereby improving the connection stability between the locking part 31 and the support structure 10 by ensuring the engagement length of the locking part 31 and the support structure 10. On the other hand, the bolt head of the self-tapping screw 40 can be located on the flange 32 and the stepped surface, which reduces the protrusion length of the bolt head and thus effectively reduces collisions. Furthermore, it allows the locking part 30 to have a better contact effect with the mounting plate 200, improving the stability of the connection.

[0044] Furthermore, such as Figure 1 and Figure 2As shown, the support structure 10 is provided with a flange 12, and the first sealing structure 20 is provided with a slot 22. The flange 12 and the slot 22 are inserted into each other. Specifically, in this embodiment, both the support structure 10 and the first sealing structure 20 are arranged in a ring shape, so that the flange 12 and the slot 22 are also arranged in a ring shape. The insertion and engagement of the slot 22 and the flange 12 can improve the ease of connection between the support structure 10 and the first sealing structure 20. At the same time, when the sealing installation device is installed on the mounting plate 200, the flange 12 can press part of the structure of the first sealing structure 20 onto the mounting plate 200, thereby ensuring the sealing performance between the mounting plate 200 and the sealing installation device and ensuring the effect of use.

[0045] Furthermore, such as Figure 1 and Figure 2 As shown, the first sealing structure 20 also includes an annular lip, which is disposed on the end face of the first sealing structure 20 facing the mounting plate 200. Specifically, in this embodiment, the annular lip further enhances the sealing performance between the first sealing structure 20 and the mounting plate 200, ensuring the sealing performance between the sealing mounting device and the mounting plate 200.

[0046] Furthermore, at least two annular lips are provided, and these at least two annular lips are radially spaced apart along the first sealing structure 20. Specifically, the radially spaced annular lips along the first sealing structure 20 create a multi-stage seal between the first sealing structure 20 and the end face of the mounting plate 200, thereby improving the sealing performance after the sealing device is installed on the mounting plate 200 and ensuring the effectiveness of use. In this embodiment, three annular lips are provided, namely a first annular lip 23, a second annular lip 24, and a third annular lip 25 arranged sequentially along an axis away from the first sealing structure 20. The heights of the first annular lip 23 and the third annular lip 25 are both higher than the height of the second annular lip 24, thereby ensuring the sealing effect. In other embodiments, the number of annular lips can be specifically set according to actual use, and is not limited here.

[0047] Furthermore, the second sealing structure is cement-resistant, with cement-resistant filling disposed between the inner wall of the through hole 21 and the wire harness 100. Specifically, in this embodiment, the cement-resistant material is disposed between the wire harness 100 and the inner wall of the through hole 21, which can fill the gap between the wire harness 100 and the inner wall of the through hole 21, thereby ensuring the sealing performance between the sealing installation device and the wire harness 100.

[0048] In another embodiment, the inner wall of the wire hole 11 and the wire harness 100 may be filled with cement-resistant material, or the inner wall of the wire hole 11 and the wire harness 100, as well as the inner wall of the through hole 21 and the wire harness 100, may be filled with cement-resistant material to ensure sealing performance. No limitation is made here.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
