Description

Technical Field

[0001] This utility model relates to the field of switching power supply protection technology, and in particular to a switching power supply structure with protection against accidental touch. Background Technology

[0002] With the rapid development of industrial automation, smart homes and other fields, switching power supplies, as the core components of power conversion and distribution, are being used in increasingly wider scenarios and are often in environments accessible to people. When switching power supplies are working, the internal electronic components carry a certain voltage. If there are no effective protective measures, accidental contact with these electronic components by personnel or external objects can easily cause safety accidents such as electric shock and short circuits. At the same time, the connecting wires of switching power supplies are a key part of power transmission. If they become loose or fall off due to accidental contact or pulling, it will not only affect the normal operation of the equipment, but may also pose a risk of electric shock due to exposed wires. At present, although some switching power supplies are equipped with basic shells, the protective structure design is simple and it is difficult to completely prevent accidental contact, especially in terms of fixing and protecting the connecting wires.

[0003] Existing technical problems: 1. Incomplete protection against accidental contact with internal electronic components. The protective shells of existing switching power supplies are mostly open or semi-open designs with large gaps or lack of tight clamping and fixing structures. External objects can easily touch the internal electronic components through the gaps, posing a safety hazard. 2. Poor protection and fixing effect for connecting wires. In the existing technology, connecting wires are simply placed without dedicated wire clamping and fixing devices. When operating or moving equipment, personnel can easily accidentally touch the connecting wires, causing them to loosen their connection with the terminal block, or even cause the wires to fall off, leading to power outages or electric shock accidents. Therefore, it is necessary to design a switching power supply structure with accidental contact protection to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a switching power supply structure with anti-accidental touch protection, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A switching power supply structure with anti-accidental touch protection includes a base. Multiple electronic components are mounted on the upper end of the base. Slots are formed on both the upper left and upper right sides of the base. A protective device is snapped onto the upper end of the base. A terminal plate is located on the front upper end of the base. A mating hole is formed on the upper right side of the base, located to the right of the terminal plate. A wire clamping device is rotatably connected to the front left side of the protective device. Multiple connecting wires are housed within the terminal plate. A fixing bolt is threaded onto the front right side of the protective device.

[0007] Preferably, the protective device includes a protective shell, with locking strips fixedly connected to the lower left and lower right portions of the protective shell, a rear plate fixedly connected to the rear end of the protective shell, and fan shells inserted and fixedly connected to the rear left and rear right portions of the rear plate. A cooling fan is rotatably connected inside the two fan shells. Multiple heat dissipation holes are opened at the upper, left, and right ends of the protective shell. A first screw hole is opened at the front right portion of the protective shell. A connecting groove is opened at the lower front portion of the protective shell. The protective shell is snapped onto the upper end of the base.

[0008] Preferably, the wire clamping device includes a fixed wire clamp, a rotating shaft is provided at the left rear end of the fixed wire clamp, a handle groove is provided at the right front end of the fixed wire clamp, multiple interval slots are provided at the lower end of the fixed wire clamp, multiple wire pressing blocks are fixedly connected to the lower end of the fixed wire clamp, a protective layer is fixedly connected to the lower end of each of the multiple wire pressing blocks, a connecting rod is fixedly connected to the right lower end of the fixed wire clamp, a second screw hole is provided at the right front end of the fixed wire clamp, and the fixed wire clamp is rotatably connected to the left front end of the protective shell.

[0009] Preferably, the multiple electronic components are arranged in a matrix at the upper middle position of the base, and the height of the electronic components is lower than the internal height of the protective shell, and the front end face of the terminal block protrudes from the front end face of the protective shell.

[0010] Preferably, one end of each connecting wire is electrically connected to an electronic component, and the other end of the connecting wire passes through the terminal block and extends to the outside of the protective housing. The fixing bolt passes through the first screw hole and is threadedly connected to the second screw hole.

[0011] Preferably, the cross-sectional shape of the card strip and the cross-sectional shape of the card slot are both T-shaped, and the card strip and the card slot are tightly engaged. The heat dissipation holes are equidistantly linearly distributed at the upper, left and right ends of the protective shell.

[0012] Preferably, the rotating shaft extends laterally through the front left part of the protective shell, and the fixing clamp can rotate 0-90 degrees through the rotating shaft. Multiple pressure blocks and spacer slots are alternately distributed. The lower end surface of the protective layer is an arc-shaped curved surface, and the positions of the docking rod and the docking hole are vertically corresponding.

[0013] Preferably, the axis of the cooling fan coincides with the axis of the fan housing, and a 2mm gap is left between the edge of the cooling fan blades and the inner wall of the fan housing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, comprehensive and reliable anti-touch protection is achieved through the protective device. The protective shell adopts a closed design, and the lower end of the locking strip is tightly engaged with the base's locking groove, which can minimize the gap between the shell and the base, preventing external objects from touching the internal electronic components through the gap. At the same time, the protective shell completely covers the electronic components, forming a physical isolation barrier, which significantly reduces the risk of safety accidents such as electric shock and short circuit caused by accidental contact with electronic components.

[0016] 2. In this utility model, the wire clamping device plays a precise and stable protective and fixing role. After the fixing wire clamp is rotated by the shaft and covers the front end of the terminal plate, multiple wire pressing blocks and the spacer groove cooperate to classify and clamp the connecting wires, avoiding messy tangling. The protective layer at the lower end of the wire pressing block not only increases the friction with the connecting wire to prevent the wire from slipping, but also avoids damage to the wire during pressing. In addition, the insertion of the docking rod into the docking hole and the threaded connection of the fixing bolt through the first screw hole and the second screw hole can firmly fix the fixing wire clamp. Even if it is accidentally touched or pulled by external force, the connecting wire will not loosen or fall off the terminal plate, ensuring the normal operation of the equipment.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] The switching power supply structure with anti-accidental touch protection includes a base 1. Multiple electronic components 6 are arranged on the upper end of the base 1. The upper left and upper right sides of the base 1 are both provided with slots 5. A protective device 2 is snapped into the upper end of the base 1. A terminal plate 7 is provided on the upper front of the base 1. A docking hole 9 is provided on the upper right side of the base 1, and the docking hole 9 is located on the right side of the terminal plate 7. A wire clamping device 3 is rotatably connected to the front left of the protective device 2. Multiple connecting wires 4 are arranged inside the terminal plate 7. A fixing bolt 8 is threadedly connected to the front right of the protective device 2.

[0028] In this embodiment, the protective device 2 includes a protective shell 21. A retaining strip 27 is fixedly connected to the lower left and lower right portions of the protective shell 21. A rear plate 24 is fixedly connected to the rear end of the protective shell 21. A fan shell 25 is fixedly connected to the rear left and rear right portions of the rear plate 24. A cooling fan 26 is rotatably connected inside the two fan shells 25. Multiple heat dissipation holes 22 are provided at the upper, left, and right ends of the protective shell 21. A first screw hole 28 is provided at the front right portion of the protective shell 21. A connecting groove 23 is provided at the lower front portion of the protective shell 21. The protective shell 21 is snapped onto the upper end of the base 1. Multiple electronic components 6 are arranged in a matrix at the upper middle part of the base 1, and the height of each electronic component 6 is lower than the internal height of the protective shell 21. The front end face of the terminal block 7 protrudes from the front end face of the protective shell 21. The cross-sectional shape of the clip 27 and the cross-sectional shape of the slot 5 are both T-shaped, and the clip 27 and the slot 5 are tightly engaged. The heat dissipation holes 22 are equidistantly linearly distributed at the upper, left and right ends of the protective shell 21. The axis of the cooling fan 26 coincides with the axis of the fan shell 25. A 2mm gap is left between the blade edge of the cooling fan 26 and the inner wall of the fan shell 25.

[0029] Through the above scheme: the protective shell 21 of the protective device 2 is tightly engaged with the T-shaped slot 5 on the base 1 via the lower T-shaped clip 27, securely covering the electronic components 6 that are matrix-distributed in the upper middle part of the base 1. Because the height of the electronic components 6 is lower than the internal height of the protective shell 21, the protective shell 21 can effectively prevent external objects from accidentally touching the electronic components 6. At the same time, the cooling fan 26 inside the fan shell 25 on the rear plate 24 cooperates with the heat dissipation holes 22 that are linearly distributed at equal intervals on the protective shell 21. When the cooling fan 26 rotates, its axis coincides with the axis of the fan shell 25. The blade edge and the inner wall of the fan housing 25 are left with a 2mm gap to ensure that air flows smoothly in and out of the heat dissipation hole 22, forming a good heat dissipation channel and efficiently removing the heat generated by the electronic components 6. The front end of the terminal block 7 protrudes from the front end of the protective housing 21 to facilitate the connection of external lines. The first screw hole 28 on the right side of the front end of the protective housing 21 and the connecting groove 23 at the lower front end provide the structural basis for the subsequent fixing of the wire clamping device 3 and the threading of the connecting wire 4. The whole system realizes the combination of anti-accidental contact protection and efficient heat dissipation, improving the safety and stability of the switching power supply.

[0030] In this embodiment, the wire clamping device 3 includes a fixed wire clamp 31. A rotating shaft 32 is provided at the left rear end of the fixed wire clamp 31. A handle groove 33 is opened at the right front end of the fixed wire clamp 31. Multiple spacer grooves 36 are opened at the lower end of the fixed wire clamp 31. Multiple wire pressing blocks 37 are fixedly connected to the lower end of the fixed wire clamp 31. A protective layer 38 is fixedly connected to the lower end of each of the multiple wire pressing blocks 37. A connecting rod 34 is fixedly connected to the right lower end of the fixed wire clamp 31. A second screw hole 35 is opened at the right front end of the fixed wire clamp 31. The fixed wire clamp 31 is rotatably connected to the protective layer 38. At the front left of the outer casing 21, one end of the connecting wire 4 is electrically connected to the electronic component 6 one by one, and the other end of the connecting wire 4 passes through the terminal plate 7 and extends to the outside of the protective casing 21. The fixing bolt 8 passes through the first screw hole 28 and is threadedly connected to the second screw hole 35. The rotating shaft 32 passes through the front left of the protective casing 21 laterally, and the fixing clamp 31 can rotate 0-90 degrees through the rotating shaft 32. Multiple pressure blocks 37 and spacer grooves 36 are alternately distributed. The lower end surface of the protective layer 38 is an arc-shaped curved surface. The positions of the docking rod 34 and the docking hole 9 are vertically corresponding.

[0031] Through the above scheme: the fixing clamp 31 of the clamping device 3 can rotate 0-90 degrees at the front left of the protective shell 21 via the rotating shaft 32. The user can easily rotate the fixing clamp 31 through the handle groove 33. When it is necessary to organize or fix the connecting wire 4, the fixing clamp 31 is rotated to cover the front of the terminal plate 7. At this time, the docking rod 34 is inserted into the docking hole 9 to accurately position the fixing clamp 31. Multiple alternately distributed wire pressing blocks 37 cooperate with the spacer groove 36 to classify and separate the connecting wire 4 that passes through the terminal plate 7. The lower end of the wire pressing block 37 The curved protective layer 38 can prevent damage to the connecting wire 4 and increase the contact area with the connecting wire 4, thereby improving clamping stability. Finally, the fixing bolt 8 passes through the first screw hole 28 of the protective shell 21 and is threadedly connected to the second screw hole 35 of the fixing clamp 31, so that the clamping device 3 is firmly fixed, effectively preventing the connecting wire 4 from loosening or falling off due to external pulling or accidental contact, ensuring that the electrical connection between the connecting wire 4 and the electronic component 6 is stable and reliable. At the same time, the structure is simple in design, easy to operate, and convenient for subsequent maintenance or replacement of the connecting wire 4.

[0032] It should be noted that this utility model is a switching power supply structure with accidental contact protection. When this structure is in operation, the lower end of the protective device 2, via a locking strip 27, engages tightly with the slot 5 on the base 1, causing the protective shell 21 to cover multiple electronic components 6 on the upper end of the base 1, thus protecting the electronic components 6 from accidental contact. Multiple heat dissipation holes 22 on the upper, left, and right ends of the protective shell 21 work in conjunction with the cooling fan 26 inside the fan housing 25 on the rear plate 24 to accelerate airflow and dissipate heat from the electronic components 6. One end of the connecting wire 4 is electrically connected to the corresponding electronic component 6, and the other end extends through the terminal plate 7 to the outside, clamping... The fixing clamp 31 of the wire device 3 rotates on the left front end of the protective housing 21 via the rotating shaft 32. The handle groove 33 facilitates the rotation of the fixing clamp 31. When it is rotated to cover the front end of the terminal plate 7, the docking rod 34 is inserted into the docking hole 9. Multiple wire clamping blocks 37 and the lower protective layer 38 cooperate with the spacer groove 36 to clamp and fix the connecting wire 4 in categories. Then, the fixing bolt 8 passes through the first screw hole 28 of the protective housing 21 and is threaded to the second screw hole 35 of the fixing clamp 31 to complete the fixing of the wire clamping device 3, further preventing accidental contact with the connecting wire 4. At the same time, the connecting groove 23 of the protective housing 21 provides space for the connecting wire 4 to pass through, ensuring the stable operation of the overall structure and providing the function of preventing accidental contact.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
