[0002] A switched-mode power supply, abbreviated as SMPS in English, also known as a switching power supply or a switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage level into the voltage or current required by the user through different forms of architectures. The input of the switching power supply is mostly an AC power supply (such as mains power) or a DC power supply, and the output is mostly devices that require a DC power supply, such as a personal computer. The switching power supply then converts the voltage and current between the two. Compared with the traditional method of replacing the switching power supply of the whole machine, the transformation of the new plug-in frame power supply can save labor costs, save electricity consumption, and achieve cost reduction and efficiency improvement.

[0003] For the existing plug-in frame type switching power supply device, its shell is fixed with a large number of bolts. The switching power supply is not convenient to disassemble and install, cannot be quickly disassembled, is not convenient for subsequent maintenance and use. At the same time, most of the existing switching power supplies cannot achieve efficient dust prevention. After a long time of use, dust will enter the interior of the switching power supply through the heat dissipation holes, affecting the service life of the device. Therefore, it is necessary to regularly clean the dust inside the switching power supply. Content of the Utility Model

[0022] The following further elaborates on the present utility model in detail:

[0023] As Figures 1 to 5 shown, the present utility model provides an insertion-frame type switching power supply device, including an outer shell 1 and an insertion frame 2. The insertion frame 2 is fixedly installed at the rear side inside the outer shell 1. The upper cover 3 is movably clamped at the top of the outer shell 1. The outer shell 1 includes a housing 11. An upper concave edge 12 is provided at the top of the housing 11. A docking groove 13 is opened on the left side at the top of the housing 11. A side card slot 14 is opened on the right side of the housing 11. The upper cover 3 includes a cover plate main body 31. A side card edge 32 is provided above the inner side of the cover plate main body 31. The side card edge 32 is movably clamped outside the upper concave edge 12. Fixed plates 35 and second insertion bars 34 that are respectively clamped in the docking groove 13 and the side card slot 14 are fixedly connected to the inner side of the cover plate main body 31. A fixed bolt 36 located inside the outer shell 1 is threadedly installed outside the fixed plate 35. A dust-proof component 4 is movably installed outside the cover plate main body 31.

[0024] By providing the upper concave edge 12, the docking groove 13 and the side card slot 14 on the housing 11, the cover plate main body 31 is guided by clamping the side card edge 32 on the outside of the upper concave edge 12 so that the cover plate main body 31 can slide along the upper concave edge 12, and is limited by inserting the second insertion bar 34 and the fixed plate 35 into the side card slot 14 and the docking groove 13 and fixed using the fixed bolt 36, thereby reducing the number of bolts, facilitating the effective fixing and support of the switching power supply, facilitating the combined installation and disassembly of the cover plate main body 31, and further facilitating the maintenance work. By providing the dust-proof component 4 outside the upper cover 3, the card frame 41 is clamped in the card slot 39 and fixed using the card slot 39, and the heat dissipation hole 37 is covered by the dust-proof net 42, thereby reducing the entry of dust from the heat dissipation hole 37 into the outer shell 1 and improving its dust-proof effect. At the same time, the card slot 39 can be disassembled and assembled by hand-tightening, with a simple structure and convenient disassembly, cleaning and maintenance of the card frame 41.

[0025] As Figure 2 and Figure 3As shown, a first insert bar 33 is fixedly connected to the inner side of the cover plate main body 31 and is located below the fixing plate 35. The first insert bar 33 is clamped inside the housing 11, and a fixing bolt 36 is threadedly connected to the inside of the first insert bar 33.

[0026] The first insert bar 33 is clamped inside the housing 11 to ensure the limiting effect on the cover plate main body 31. At the same time, the fixing bolt 36 passes through the first insert bar 33 for fixing to ensure stable fixation.

[0027] As Figure 3 shown, a rubber strip 38 is movably clamped to the inner side of the cover plate main body 31, and heat dissipation holes 37 are equidistantly formed in the top of the cover plate main body 31.

[0028] Through the arrangement of the rubber strip 38, it fits the housing 11 when the cover plate main body 31 is installed, thereby improving the sealing effect. Through the arrangement of the heat dissipation holes 37, heat dissipation is facilitated.

[0029] As Figure 2 shown, the housing 11 is provided with openings at the top and on the right side, and the cover plate main body 31 is in an "L" shape.

[0030] Through the housing 11 having openings at the top and on the right side and cooperating with the cover plate main body 31 being in an "L" shape, the housing 11 can be covered and blocked, increasing the operable space and facilitating disassembly and maintenance.

[0031] As Figure 4 shown, a card slot 39 corresponding to the heat dissipation holes 37 is formed in the top of the cover plate main body 31, and the dust-proof assembly 4 is movably clamped inside the card slot 39.

[0032] The dust-proof assembly 4 includes a card frame 41. A dust-proof net 42 is fixedly installed inside the card frame 41, and a hand-tightening bolt 43 is threadedly installed on the outside of the card frame 41 and is located inside the cover plate main body 31.

[0033] By clamping the card frame 41 inside the card slot 39, it can slide along the card slot 39 and is fixed by the hand-tightening bolt 43. By covering the dust-proof net 42 outside the heat dissipation holes 37, external dust is blocked, reducing the influence of external dust entering the inside of the housing 11. At the same time, the card frame 41 is convenient for disassembly and facilitates intensive maintenance.

[0034] As Figure 4 shown, the card frame 41 is in an "L" shape, and the hand-tightening bolt 43 is installed on the outside of the cover plate main body 31.

[0035] With the card frame 41 being in an "L" shape, the hand-tightening bolt 43 is inserted into the cover plate main body 31 from the side of the card frame 41 for fixation. Thus, by manually tightening the hand-tightening bolt 43, it can be disassembled, facilitating sliding the card frame 41 out of the card slot 39 for cleaning, and at the same time facilitating installation and fixation.

[0036] AsFigure 4 As shown, the size of the dust-proof net 42 is adapted to the heat dissipation holes 37.

[0037] The dust-proof net 42 adapted to the heat dissipation holes 37 is used to block them to reduce external dust from entering the interior of the housing 11 through the heat dissipation holes 37.

[0038] Next, the working principle of the plug-in frame type switching power supply device will be specifically described.

[0039] As Figures 1 to 5 shown, during disassembly, by removing the fixing bolts 36, the fixing bolts 36 are successively removed from the interior of the first inserting strip 33, the housing 11 and the fixing plate 35. Subsequently, by pulling the cover plate main body 31 towards the side away from the docking groove 13, the cover plate main body 31 slides outwards to open the housing 11. During installation, by clamping the cover plate main body 31 on the top of the housing 11, the side clamping edge 32 is clamped outside the upper concave edge 12, and by pushing the cover plate main body 31 towards the docking groove 13, the fixing plate 35 is clamped into the docking groove 13 through the sliding of the cover plate main body 31. At the same time, the first inserting strip 33 is clamped inside the housing 11, and the second inserting strip 34 is clamped into the side clamping groove 14. The fixing bolts 36 are used to connect and fix by passing through the fixing plate 35, the housing 11 and the first inserting strip 33. The cover plate main body 31 is limited by the side clamping edge 32, the first inserting strip 33 and the second inserting strip 34. Heat dissipation is carried out through the heat dissipation holes 37 on the cover plate main body 31, and dust prevention is carried out through the dust-proof net 42 installed in the card slot 39 outside the heat dissipation holes 37 to prevent dust from entering the housing 11. During maintenance, by turning the hand-tightening bolt 43 located outside the cover plate main body 31, the hand-tightening bolt 43 is disengaged from the interior of the cover plate main body 31. By pulling the card frame 41 outwards, the dust-proof net 42 is pulled out from the card slot 39 to clean the external dust and then installed back in place.

[0040] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are all within the protection scope of the present utility model.
