Description

Technical Field

[0001] This utility model relates to the field of switching power supply technology, specifically to a switching power supply with good waterproof performance. Background Technology

[0002] A switching power supply, also known as a switching converter or switching power supply, is a high-frequency power conversion device and a type of power supply. Its main function is to convert a voltage at a certain level into the voltage or current required by the user through different architectures.

[0003] In traditional switching power supplies, the upper and lower casings are usually simply spliced ​​together or fixed with a few screws, lacking an effective waterproof barrier. This allows moisture to directly contact the electronic components inside the power supply, resulting in a relatively high risk of short circuits and damage. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof switching power supply that solves the problem that in traditional switching power supplies, the upper and lower casings are usually simply spliced ​​together or fixed with a few screws, lacking an effective waterproof barrier.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a waterproof switching power supply, comprising a lower housing, a switching power supply body, and an upper housing. The switching power supply body is fixedly installed inside the lower housing, and the upper housing is fixedly installed on the outer surface of the lower housing. An exhaust fan is fixedly installed inside the upper housing, and several heat dissipation vents are provided on the upper surface of the upper housing. Terminals are installed on the outer surface of the switching power supply body. Mounting mechanisms are installed on both sides of the lower housing, and waterproof mechanisms are inserted into the mounting mechanisms. The waterproof ends of the waterproof mechanisms cover the outer surfaces of the upper and lower housings.

[0006] Furthermore, the waterproof mechanism includes a waterproof shell, which is disposed on the outer surface of the lower shell and the upper shell. A set of buckles is fixedly installed on the lower surface of both ends of the waterproof shell, and the number of buckles in each set is fixed to two.

[0007] Furthermore, a water guide groove is provided on one side of the waterproof shell.

[0008] Furthermore, a plurality of limiting grooves are provided on one side of the waterproof shell, and the limiting grooves are located on one side of the wiring terminal.

[0009] Furthermore, the mounting mechanism includes a fixing seat, which is fixedly installed on one side of the lower housing, and the fixing seat has two snap-fit ​​grooves inside.

[0010] Furthermore, the buckle is inserted into the interior of the fixing base and engages with the snap-fit ​​groove.

[0011] This utility model has the following beneficial effects: (1) In this utility model, the buckle is inserted into the fixed base and squeezed and deformed into the fixed base. Then, when the snap-fit ​​groove and the snap-fit ​​end are aligned, the snap-fit ​​snaps back and snaps into the snap-fit ​​groove, thus completing the installation of the waterproof shell. The waterproof shell covers the outer surface of the lower shell and the upper shell to prevent external moisture from entering. Furthermore, a water guide groove is provided on one side, and the water will flow away along the water guide groove to avoid accumulating on the surface of the switching power supply. This effectively prevents external moisture from entering the switching power supply, reduces short circuits and damage caused by moisture, and improves the working reliability of the switching power supply in a humid environment.

[0012] (2) The present invention has a limiting groove on one side of the waterproof shell, which is set on one side of the wiring terminal. When wiring the wiring terminal, the limiting groove can limit the line connected to the wiring terminal, thus avoiding the situation of messy placement.
