Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, in particular to a switching power supply protection cover. Background Art

[0002] A switching power supply is a high-frequency power conversion device. Its primary function is to convert a voltage level into the voltage or current required by the user through various architectures. Compared to linear power supplies, it offers higher conversion efficiency, is compact, and is lightweight, making it widely used in various electronic devices.

[0003] Patent publication number "CN218277398U" discloses a "safety shield for a switching power supply." The shield comprises a base plate and a protective shield located on top of the base plate. A cavity for placing the switching power supply is formed between the base plate and the protective shield. Hooks are connected to the four corners of the bottom surface of the shield. The lower half of the hooks extends into a mounting slot defined in the top surface of the base plate. A spring seat is connected to the inner wall of the mounting slot, and a compression spring is connected to one end of the spring seat. The end of the compression spring, remote from the spring seat, is connected to a clip that engages with the hook. The clip is slidably connected to the inner wall of the mounting slot via a slider connected to the bottom surface. A toggle lever is connected to the outer wall of the clip. A wire-combing mechanism is provided on one outer wall of the shield. The wire-combing mechanism includes a fixing plate that fits into a mounting opening defined in the outer wall of the shield. This safety shield for a switching power supply has a simple structure and is easy to disassemble.

[0004] The device in the aforementioned patent moves the two toggle levers relative to each other, causing the toggle levers to drive the clamping member to move in the mounting groove in the base plate, thereby compressing the compression spring and releasing the clamping member from the engagement with the hook member. This facilitates installation or removal of the protective cover and meets the maintenance personnel's needs for quick maintenance. However, if the distance between the two toggle levers is too large, then when pressing the toggle lever on one side, it may be difficult to effectively press the toggle lever on the other side, resulting in problems such as difficulty in achieving efficient removal with this operation method, which may affect the efficiency and speed of maintenance work.

[0036] The control mechanism 3 includes a card slot 31 and a working slot 33. One end of the working slot 33 is respectively provided with a side of the inner wall of the card slot 31, and a sliding slot 36 is respectively provided on one side of the working slot 33, and a sliding slot 39 is respectively provided on one side of the sliding slot 36.

The holding block 44 provides an elastic holding effect through the third spring 43 installed at the top. When the connecting wire needs to be replaced or adjusted, the holding block 44 can be easily moved upward by simply toggling the pressing block 45, allowing the connecting wire to smoothly complete the disengagement action, which is convenient for subsequent operations. When installing the connecting wire, the holding block 44 is also moved upward by toggling the pressing block 45 to provide space for the connecting wire to pass through the through hole 41, and then the pressing block 45 is released, and the holding block 44 can firmly hold the connecting wire to ensure the reliability and stability of the connection.

As the connecting rod 38 moves, it can drive the limit block 35 to disengage from the card block 32, realizing a quick disassembly function and providing convenient conditions for subsequent efficient maintenance. When the card is released, the first spring 34 installed on the other end of the inner wall of the working groove 33 pushes the limit block 35 to be clamped on one side of the card block 32 to achieve a control effect. Then the connecting rod 38 is installed on the second spring 37 through the other end, and is in a conflicting state under the action of the elastic force, and the two sides of the pressing block 310 are slidably connected between the inner sides of the sliding groove 39. The sliding groove 39 is respectively opened on one side of the inner wall of the sliding groove 36 and passes through the two side surfaces of the bottom plate 1.

When installing the connecting wire, the holding block 44 is also moved upward by toggling the pressing block 45 to provide space for the connecting wire to pass through the through hole 41, and then the pressing block 45 is released, and the holding block 44 can firmly hold the connecting wire to ensure the reliability and stability of the connection.

[0048] The heat dissipation mechanism 5 can effectively dissipate internal heat through the fans 52 installed inside the ventilation ducts 51, and then the dust-proof mesh cover 53 at the top of the ventilation duct 51 can effectively prevent dust from entering the interior. The heat-dissipating air is discharged through the ventilation holes 54 on both sides of the inner wall of the outer cover 2, which are respectively opened and penetrate the two side surfaces.
