[0002] Switching power supplies are common high-frequency power conversion devices widely used in electrical equipment. Existing switching power supply housings typically consist of two L-shaped aluminum alloy shells, which have limited assembly stability. Chinese patent CN202320323702.8 discloses a switching power supply housing comprising an upper shell and a lower shell. The upper shell has a circuit board slot for inserting the switching power supply circuit board. During installation, the circuit board is directly inserted into the slot in the upper shell without bolt tightening, making the operation simple and efficient. While this meets general usage requirements, it cannot effectively seal the connection at both ends, which to some extent affects the reliability of the internal structure. Furthermore, disassembly and assembly are inconvenient and inefficient, limiting its applicability. Summary of the Invention

[0031] 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. Example

[0032] See Figures 1 to 6 As shown, a snap-fit ​​LED switching power supply housing includes a housing 1 and end cap structures 2 disposed at both ends of the housing. The end cap structure includes an end cap insertion plate 21, an end cap support panel 22, and an end cap flip-up plate 23. The power circuit board is located inside the housing, and both ends are sealed by the end cap structure, so that the connection terminals of the power circuit board are located inside the end cap structure.

[0033] During processing, the plug support panel is integrally formed on the outer end of the plug insert plate, and the two are arranged in an L-shape; a flip cover clearance groove 24 is provided in the middle of the connection between the plug support panel and the plug insert plate; a strip-shaped slot 25 is provided on the top surface of the inner end of the plug insert plate, and two flip cover positioning holes 26 are provided on the bottom surface of the inner end of the plug insert plate; a strip-shaped protrusion 27 is provided on the symmetrical outer wall of the plug insert plate; in this embodiment, the length and thickness of the strip-shaped protrusion can be processed and set as needed, mainly for assembly and snap-fit ​​connection with the shell, while the strip-shaped slot is mainly for snap-fit ​​connection with the end of the arc-shaped top cover of the shell.

[0034] During processing, a semi-circular protrusion 28 is integrally formed at the end of the plug flip cover, and a shaft protrusion 29 is integrally formed on the symmetrical side of the semi-circular protrusion. During assembly, the plug flip cover is placed in the flip cover recess, and the semi-circular protrusion is rotatably connected to the cover positioning hole. The plug structure is snapped into both ends of the housing and is connected to the housing by a strip-shaped groove and a strip-shaped protrusion. It can be snapped in place and flipped over by a shaft, facilitating the connection operation of the power circuit board's connection terminals.

[0035] In this embodiment, the housing includes a U-shaped bottom shell 11 and an arched top cover 12. The bottom surfaces at both ends of the arched top cover are provided with insert protrusions 13 that mate with the strip-shaped slots. A locking protrusion 14, aligned with the strip-shaped protrusion, is integrally formed on the symmetrical edges of the arched top cover. Simultaneously, a C-shaped groove 15 is provided on the upper part of the symmetrical inner wall of the U-shaped bottom shell. Both the strip-shaped protrusion and the locking protrusion are engaged in the C-shaped groove for positioning. The insert protrusion is engaged in the strip-shaped slot for limiting its position. This structure, through snap-fit ​​connection, reduces the use of screws and improves the convenience and effectiveness of assembly.

[0036] In this embodiment, several positioning cavities 3 are provided at both ends of the symmetrical inner wall of the U-shaped bottom shell; simultaneously, a positioning protrusion 4 that mates with the positioning cavities is integrally formed on the inner side of the plug support panel; during assembly, the inner side of the plug support panel is attached to the end face of the U-shaped bottom shell, and the positioning protrusion is inserted and limited within the positioning cavity. This improves the ease of connection and the stability of installation, and prevents the U-shaped bottom shell from loosening or shifting.

[0037] In this embodiment, a circuit board terminal limiting piece 5 is provided on the inner top surface of the plug plate. This is a conventional structure in the prior art, and it is simply applied. The length of the circuit board terminal limiting piece matches the width of the inner cavity of the U-shaped bottom shell. In use, the circuit board terminal limiting piece is inserted into the U-shaped bottom shell, and its two ends are positioned against the symmetrical inner wall of the U-shaped bottom shell.

[0038] Meanwhile, in this embodiment, a limiting abutment 6 is provided on the bottom edge of the inner side of the plug support panel, and the limiting abutment abuts against the top surface of the bottom wall of the U-shaped bottom shell. This increases the contact area with the U-shaped bottom shell, improving the stability and reliability of the connection. The arched top cover is provided with heat dissipation slots 7, which helps improve heat dissipation performance.

[0039] This utility model has positive effects: The structure of this utility model is reasonable. Its plug structure includes a plug insert plate, a plug support panel and a plug flip cover plate. The structure is connected by a snap-fit ​​method. At the same time, it is connected to the shell by a strip groove and a strip protrusion, which reduces the use of screws, improves the convenience and effectiveness of assembly, is stable and reliable in use, helps to improve assembly and maintenance efficiency, and has strong applicability.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
