Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, and specifically to a highly waterproof power adapter. Background Technology

[0002] Power adapters, as key power supply components for electronic devices, are widely used in laptops, smart homes, and outdoor electronic equipment. With the diversification of application environments, the requirements for their waterproof performance are increasing. In existing technologies, power adapter housings typically employ a snap-fit ​​structure between the upper and lower shells, and waterproof designs often rely on a single sealing ring or simple seam sealing, which has the following shortcomings.

[0003] Single-seal structures are prone to seal failure due to assembly errors, material aging, or external vibrations. Moisture can easily seep into the interior through the shell seams, causing short circuits, component damage, or even safety accidents. In humid environments, outdoor rainy days, or scenarios with a lot of water mist, existing waterproof structures are difficult to effectively prevent moisture intrusion. Some complex waterproof structures require additional sealing rings, which not only increases the assembly difficulty but may also lead to a decrease in waterproof performance due to seal detachment or wear.

[0031] The present invention will be further described in conjunction with the following embodiments.

[0032] Depend on Figures 1 to 10 As can be seen, the highly waterproof power adapter described in this embodiment includes an upper shell 1 and a lower shell 2;

[0033] The bottom of the upper shell 1 is provided with an upper enclosure plate 11; the outer periphery of the upper enclosure plate 11 is provided with a first upper waterproof baffle 12; the upper enclosure plate 11 is provided with a second upper waterproof baffle 13 on the inner side of the first upper waterproof baffle 12; an upper waterproof groove 14 is formed between the first upper waterproof baffle 12 and the second upper waterproof baffle 13.

[0034] The lower shell 2 is provided with a lower enclosure plate 21 at the top; a first lower waterproof baffle 22 is provided on the outer periphery of the lower enclosure plate 21; a second lower waterproof baffle 23 is provided on the inner side of the first lower waterproof baffle 22; a lower waterproof groove 24 is formed between the first lower waterproof baffle 22 and the second lower waterproof baffle 23.

[0035] The first upper waterproof baffle 12 is disposed in the lower waterproof groove 24; the second lower waterproof baffle 23 is disposed in the upper waterproof groove 14.

[0036] Specifically, the highly waterproof power adapter described in this embodiment has a double-nested labyrinthine waterproof structure formed by embedding the first upper waterproof baffle 12 of the upper shell 1 into the lower waterproof groove 24 of the lower shell 2, and embedding the second lower waterproof baffle 23 of the lower shell 2 into the upper waterproof groove 14 of the upper shell 1. This structure extends the water penetration path. When water comes into contact with the shell seam, it needs to break through the two nested baffles and groove barriers in sequence, effectively preventing liquid and water vapor from entering the interior. Furthermore, the structure is stable and highly reliable, does not rely on easily aging seals, reduces the risk of waterproof failure due to material wear, and has a longer service life.

[0037] This embodiment describes a highly waterproof power adapter, in which an upper fusion splice 15 is provided at the bottom of the first upper waterproof baffle 12. The upper fusion splice 15 can be welded to the bottom of the lower waterproof groove 24 during assembly using processes such as ultrasonic welding, forming a sealed connection between the mating surfaces of the first upper waterproof baffle 12 and the lower waterproof groove 24. This eliminates gaps between them, further strengthening the sealing performance of the first waterproof barrier and preventing moisture from seeping in from the mating area between the first upper waterproof baffle 12 and the lower waterproof groove 24.

[0038] The highly waterproof power adapter described in this embodiment has a lower fusion weld 25 at the bottom of the second lower waterproof baffle 23. The upper fusion weld 15 can be fused to the bottom of the lower waterproof groove 24 during assembly using processes such as ultrasonic welding, so that the mating surfaces of the first upper waterproof baffle 12 and the lower waterproof groove 24 form a sealed connection, eliminating the gap between them, further strengthening the sealing performance of the first waterproof barrier, and preventing moisture from seeping in from the mating area of ​​the first upper waterproof baffle 12 and the lower waterproof groove 24.

[0039] In this embodiment, a highly waterproof power adapter is described, wherein the length of the first upper waterproof baffle 12 is greater than the length of the second upper waterproof baffle 13; and the length of the second lower waterproof baffle 23 is greater than the length of the first lower waterproof baffle 22. This dimensional design causes the endpoints of the two waterproof barriers to be misaligned, preventing the gaps from aligning and forming a straight penetration channel, further extending the water penetration path, increasing penetration resistance, and improving the redundancy of the waterproof structure. Even if a tiny gap appears in one barrier, the other barrier can still effectively block water.

[0040] The highly waterproof power adapter described in this embodiment has an upper interface 31 at the end of the upper panel 11 and a lower interface 32 at the end of the lower panel 21. An installation interface 3 is formed between the upper interface 31 and the lower interface 32. The highly waterproof power adapter also includes a waterproof connector 4, which is located at the installation interface 3.

[0041] This embodiment describes a highly waterproof power adapter. The waterproof connector 4 is equipped with a first limiting plate 51 and a second limiting plate 52. The first limiting plate 51 abuts against the outer side of the mounting interface 3, and the second limiting plate 52 abuts against the inner side of the mounting interface 3. The first limiting plate 51 and the second limiting plate 52 clamp and fix the mounting interface 3 from both the inner and outer sides, ensuring the relative position of the waterproof connector 4 and the mounting interface 3 is stable. This prevents the connector from loosening or shifting due to vibration, external pulling, etc., prevents the sealing structure from failing, and ensures waterproof stability during long-term use.

[0042] This embodiment describes a highly waterproof power adapter. The waterproof connector 4 has a first blocking rib 53 between a first limiting plate 51 and a second limiting plate 52; a welding groove 55 is provided between the first limiting plate 51 and the first blocking rib 53; the mounting interface 3 has a welding rib 61 that mates with the welding groove 55; and the welding rib 61 has a waterproof weld line 62. The cooperation between the welding groove 55 and the welding rib 61 increases the contact area between the waterproof connector 4 and the mounting interface 3. The waterproof weld line 62, through welding, forms a tight seal between the two, creating a first welded waterproof barrier on the outside of the connector, directly preventing external moisture from seeping in through the gaps between the connector and the interface, thus strengthening the primary waterproof capability at the interface.

[0043] This embodiment describes a highly waterproof power adapter. The mounting interface 3 is provided with a dispensing groove 63. A first blocking ridge 53 is located within the dispensing groove 63. Sealant is applied between the first blocking ridge 53 and the dispensing groove 63. The sealant fills the space between the first blocking ridge 53 and the dispensing groove 63, forming a second adhesive sealing barrier on top of the welded seal. The sealant has good extensibility and sealing properties, can fill tiny gaps, and can adapt to thermal expansion and contraction caused by temperature changes, preventing new gaps from forming due to material deformation and improving the waterproof durability of the interface.

[0044] This embodiment describes a highly waterproof power adapter. A second blocking rib 54 is provided between the first blocking rib 53 and the second limiting plate 52; a first waterproof groove 56 is formed between the first blocking rib 53 and the second blocking rib 54; the mounting interface 3 is provided with a first waterproof rib 64 that mates with the first waterproof groove 56; a second waterproof groove 57 is formed between the second blocking rib 54 and the second limiting plate 52; and the mounting interface 3 is provided with a second waterproof rib 65 that mates with the second waterproof groove 57. The multi-layered nested structure of grooves and ribs forms a labyrinthine waterproof path inside the waterproof connector 4. Water must sequentially overcome the barriers formed by the first waterproof groove 56 and the first waterproof rib 64, and the second waterproof groove 57 and the second waterproof rib 65, further extending the penetration path. Each layer can block some water, and the multiple layers significantly improve the waterproof level at the interface. Furthermore, a sealing ring can be provided between the second waterproof groove 57 and the second waterproof rib 65 to further improve the overall sealing performance.

[0045] This embodiment describes a highly waterproof power adapter, wherein the mounting interface 3 is provided with a limiting groove 66 that mates with the second blocking protrusion 54. The engagement of the limiting groove 66 and the second blocking protrusion 54 further secures the position of the waterproof connector 4, preventing the connector from shifting due to vibration or external force during long-term use. This ensures precise engagement between the first and second waterproof grooves 57 and their corresponding protrusions, maintains the stability of the multi-layered waterproof structure, and guarantees long-term effective waterproof performance at the interface.
