[0001] This utility model relates to the field of LED power supply technology, specifically to a plug-in LED power supply. Background Technology

[0002] An LED power supply is a type of power supply that provides power to LED devices. It uses a transformer and rectifier to convert alternating current into direct current to drive LED lights to emit light. Current LED power supplies typically include a housing, a PCB board, and a plug.

[0003] However, with existing plug-in LED power supplies, dust in the air can enter the protective shell through the holes in the casing and adhere to the electrical components inside the power supply body, easily causing short circuits. In addition, the input and output lines of LED power supplies are mostly soldered to the power supply body, and users often drag and bend the connecting lines. After long-term use, the metal at the solder joints is prone to fatigue and breakage, reducing the lifespan of the LED power supply and making it difficult to promote its use.

[0004] To address this problem, this application provides a plug-in LED power supply. Utility Model Content

[0005] The purpose of this utility model is to provide a plug-in LED power supply to solve the problems mentioned in the background art, such as dust in the air entering the interior of the protective shell through the holes in the shell during LED power supply use, and the metal at the solder joint being prone to fatigue fracture after long-term use, which can easily cause short circuits, reduce the lifespan of the LED power supply, and result in poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A plug-in LED power supply includes a mounting assembly, a heat dissipation assembly, and a fixing assembly. The mounting assembly includes a protective shell and a connecting cover, with the connecting cover fixedly mounted on the top of the protective shell. The heat dissipation assembly is disposed inside the mounting assembly and includes a filter, an inner sealing shell, and heat dissipation fins.

The fixing assembly is disposed inside the mounting assembly and includes an upper fixing block and a gasket. The upper fixing block is movably mounted inside the protective shell, and the gasket is movably connected inside the upper fixing block.

[0007] A further improvement of this utility model is that: both ends of the protective shell are fixedly connected with fixing ears, the top of the protective shell is provided with a fixing hole, the power supply body is fixedly installed inside the protective shell, and the inner sealing shell is disposed outside the power supply body.

[0008] A further improvement of this utility model is that: both ends of the power supply body are provided with connecting wires, and the other end of the connecting wires is fixedly installed with a connector.

[0009] A further improvement of this utility model is that an air inlet is provided on one side of the protective shell, and the filter screen is fixedly installed inside the air inlet.

[0010] A further improvement of this utility model is that a fixing frame is fixedly installed inside the protective shell, and a cooling fan is fixedly installed inside the fixing frame.

[0011] A further improvement of this utility model is that: heat-conducting plates are fixedly installed on both sides of the power supply body, and the other side of the heat-conducting plate is movably connected to the inside of the inner sealing shell. A wire-passing port is opened inside the inner sealing shell, and the connecting wire is movably connected to the inside of the wire-passing port.

[0014] 2. This utility model provides a plug-in LED power supply. Through the combined action of the connecting cover, the upper fixing block and the gasket, the connecting cover presses down on the upper fixing block and the gasket, fixing the connecting wire between the gasket and the lower fixing block.

[0017] The present invention will be further described in detail below with reference to embodiments: like Figure 1-6 As shown, this utility model provides a plug-in LED power supply, including a mounting component 1, a heat dissipation component 2, and a fixing component 3. The heat dissipation component 2 cools the power supply body 14 and prevents short circuits caused by dust adhering to the electrical components in the power supply body 14. The fixing component 3 fixes the connecting wire 16 to prevent metal fatigue fracture at the weld between the connecting wire 16 and the power supply body 14 after long-term use.

[0018] like Figure 2 and Figure 5 As shown, the mounting assembly 1 includes a protective shell 10 and a connecting cover 11. The connecting cover 11 is fixedly mounted on the top of the protective shell 10. The top end of the upper fixing block 31 is movably connected to the bottom end of the connecting cover 11. The connecting cover 11 applies pressure to the upper fixing block 31 to fix the connecting line 16.

[0019] like Figure 2 As shown, both ends of the protective shell 10 are fixedly connected with fixing ears 12, which can be used to fix the LED power supply.

[0020] like Figure 3 and Figure 4 As shown, a fixing hole 13 is provided on the top of the protective shell 10. The power supply body 14 is fixedly installed inside the protective shell 10. The inner sealing shell 22 is set outside the power supply body 14. By setting the inner sealing shell 22 outside the power supply body 14, the power supply body 14 is in a closed environment, which can prevent dust from adhering to the electrical components in the power supply body 14.

[0021] like Figure 2 , Figure 4 and Figure 5As shown, both ends of the power supply body 14 are provided with connecting wires 16, and the other end of the connecting wires 16 is fixedly installed with a connector 15, through which the power supply and the LED light are connected.

[0022] like Figure 3 , Figure 4 and Figure 6 As shown, the heat dissipation component 2 is located inside the mounting component 1. The heat dissipation component 2 includes a filter screen 20, an inner sealing shell 22, and heat dissipation fins 23. The inner sealing shell 22 is fixedly installed inside the protective shell 10, and the heat dissipation fins 23 are fixedly installed outside the inner sealing shell 22. Heat conduction plates 24 are fixedly installed on both sides of the power supply body 14. The other side of the heat conduction plate 24 is movably connected to the inside of the inner sealing shell 22. A wire through hole 27 is opened inside the inner sealing shell 22, and the connecting wire 16 is movably connected inside the wire through hole 27. The heat generated by the power supply body 14 is conducted to the inner sealing shell 22 through the heat conduction plate 24, and then heat is exchanged with the air through the heat dissipation fins 23, carrying the heat out of the protective shell 10.

[0023] like Figure 1 and Figure 3 As shown, an air inlet 25 is provided on one side of the protective shell 10, and a filter screen 20 is fixedly installed inside the air inlet 25 to block larger foreign objects in the air.

[0024] like Figure 2 and Figure 6 As shown, a mounting bracket 26 is fixedly installed inside the protective shell 10, and a cooling fan 21 is fixedly installed inside the mounting bracket 26. By rotating the cooling fan 21, air is drawn into the interior of the protective shell 10 through the air inlet 25 and exchanges heat with the heat dissipation fins 23 on the inner sealing shell 22.

[0025] like Figure 2 and Figure 6 As shown, the fixing component 3 is disposed inside the mounting component 1. The fixing component 3 includes an upper fixing block 31 and a gasket 32. The upper fixing block 31 is movably mounted inside the protective shell 10, and the gasket 32 ​​is movably connected inside the upper fixing block 31. Lower fixing blocks 30 are fixedly mounted at both ends of the protective shell 10. The connecting wire 16 is disposed at the top of the lower fixing block 30 and movably connected to the bottom of the gasket 32, so that the connecting wire 16 is positioned between the gasket 32 ​​and the lower fixing block 30 and is fixed therein. When the connecting wire 16 is dragged and bent, the weld joint between the connecting wire 16 and the power supply body 14 is not subjected to stress, thereby improving the service life of the LED power supply.

[0026] The working principle of this plug-in LED power supply will be explained in detail below.

[0027] like Figure 1-6As shown, when using this plug-in LED power supply, it is fixed by the fixing ears 12, and then the power supply and LED light are connected by the plugs 15 at both ends of the protective shell 10. When the power supply is working, the heat generated by the power supply body 14 is conducted to the inner sealing shell 22 through the heat conduction plate 24. At the same time, the cooling fan 21 rotates, drawing air into the interior of the protective shell 10 through the air intake 25, so that the air comes into contact with the heat dissipation fins 23 on the inner sealing shell 22 and carries the heat out of the protective shell 10. When the air is drawn into the interior of the protective shell 10, the filter screen 20 will filter out the heat in the air. Large foreign objects are blocked, and the presence of the inner sealing shell 22 keeps the power supply body 14 in a closed environment, which can prevent short circuits caused by dust adhering to the electrical components in the power supply body 14. Furthermore, a lower fixing block 30, an upper fixing block 31, and a gasket 32 ​​are provided at both ends of the protective shell 10. During installation, the connecting cover 11 will press down on the upper fixing block 31 and the gasket 32 ​​to fix the connecting wire 16 between the gasket 32 ​​and the lower fixing block 30. This ensures that when the connecting wire 16 is dragged and bent, the welded joint between the connecting wire 16 and the power supply body 14 is not stressed, thereby improving the service life of the LED power supply.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
