Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically a multifunctional waterproof wire harness. Background Technology

[0002] In modern electronic equipment and electrical systems, cables serve as crucial carriers of signals and power transmission, and their waterproof performance plays a decisive role in the system's stability and lifespan. Currently, the industry commonly employs a waterproofing method that involves encasing the cable in a waterproof shell and injecting sealant into both ends of the shell. This method aims to fill the gap between the cable and the shell with sealant, forming a waterproof barrier.

[0003] However, the existing waterproofing methods mentioned above are insufficient: on the one hand, to ensure a sealing effect, a large amount of sealant needs to be injected, which not only increases production costs but also reduces production efficiency; on the other hand, because the cable has a certain amount of space to move inside the waterproof casing, the movement of the cable during the sealant injection process can easily cause gaps, air bubbles, or uneven filling of the sealant. These defects will seriously weaken the sealing performance of the sealant, allowing external moisture and humidity to seep in along the gaps, leading to faults such as cable short circuits and insulation aging, ultimately affecting the safe operation of the entire electrical system. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a multifunctional waterproof wire harness, which effectively overcomes the problems of traditional cable waterproofing technology.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional waterproof wire harness, comprising a waterproof outer shell that surrounds the cable for waterproofing; a cap installed at the end of the waterproof outer shell; a through hole for the cable to pass through the cap; a storage groove for storing sealant on the outside of the through hole; sealant filled in the storage groove for sealing the through hole; and a second storage groove for storing sealant on the inner wall of the cap; sealant filled in the second storage groove for sealing the waterproof outer shell and the cap.

[0008] Furthermore, a sealing ring is provided inside the through hole.

[0009] Furthermore, a positioning element that can be inserted into the waterproof outer shell is fixedly provided on the inner side of the cover.

[0010] Furthermore, the positioning element is a cylindrical positioning cylinder.

[0011] Furthermore, the inner diameter of the positioning cylinder is larger than the outer diameter of the cable, and the outer diameter of the positioning cylinder is smaller than the inner diameter of the waterproof shell.

[0012] Furthermore, the outer wall of the cover is provided with anti-slip texture.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a multifunctional waterproof wire harness with the following advantages:

[0015] This multifunctional waterproof wire harness, by installing a cap at the end of the waterproof outer shell and by setting a storage groove 1 on the outside of the through hole of the cap and opening a storage groove 2 on the inner wall, precisely limits the filling area of ​​the sealant within a specific space. Compared with the traditional method of directly injecting a large amount of sealant into the waterproof shell, it significantly reduces the amount of sealant used and effectively reduces material and production costs.

[0016] The storage tank is located on the outside of the cap, allowing staff to visually observe the glue injection process and confirm the glue filling status in real time. This avoids waterproofing failure caused by air bubbles, gaps, or uneven filling inside the sealant, effectively improving the waterproofing effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model discloses a multifunctional waterproof wire harness, comprising a waterproof outer shell 1 that surrounds a cable 2 for waterproofing. A cap 3 is installed at the end of the waterproof outer shell 1, and a through hole 4 for the cable 2 to pass through is provided on the cap 3. A storage tank 5 for storing sealant is provided outside the through hole 4. The sealant is filled into the storage tank 5 to seal the through hole 4. The storage tank 5 is located outside the cap 3, allowing workers to visually observe the sealant filling process and confirm the sealant filling status in real time, thus avoiding air bubbles inside the sealant and improving the waterproof effect.

[0025] The inner wall of the cover 3 is provided with a storage tank 2 8 for storing sealant. The sealant is filled in the storage tank 2 8 to seal the waterproof outer shell 1 and the cover 3.

[0026] Storage tank 5 and storage tank 2 8 are opened on the inner wall to precisely limit the filling area of ​​the sealant within a specific space, thereby reducing the amount of sealant used.

[0027] A sealing ring 6 is provided inside the through hole 4 to provide a seal and effectively reduce the flow of sealant into the waterproof housing 1.

[0028] A positioning element, which can be inserted into the waterproof outer shell 1, is fixedly installed on the inner side of the cover 3. The positioning element is a cylindrical positioning cylinder 7, the inner diameter of which is larger than the outer diameter of the cable 2, and the outer diameter of which is smaller than the inner diameter of the waterproof outer shell 1. This serves to position the cable and improve the stability of the cover 3 during installation.

[0029] The outer wall of the cover 3 is provided with anti-slip texture 9, which plays a protective role when the cover 3 is installed.

[0030] In summary, when using this multifunctional waterproof wire harness, a glue gun or applicator is used to evenly fill the sealant into the storage groove 2 8 on the inner wall of the cap 3, ensuring that the sealant layer is continuous and uninterrupted, and the thickness covers 80%-90% of the groove depth.

[0031] Pass the cable 2 through the through hole 4 of the cover 3, align the end of the waterproof housing 1 with the installation position of the cover 3, and securely install the cover 3 onto the waterproof housing 1 using the sealant in the storage slot 2 8.

[0032] After the cap 3 is fixed, inject sealant into the storage tank 5 on the outside of the cap 3, filling it to be flush with the opening of the tank, ensuring that the sealant completely fills the through hole 4 and the storage tank 5 and wraps the cable 2. When injecting the sealant, observe the state of the sealant in the storage tank 5 to avoid air bubbles remaining.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
