For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Please refer to Figures 1 to 4 The utility model provides an LED power supply housing, including a bottom shell 1 and an upper cover 2, the outer side walls on the left and right sides of the bottom shell 1 are both provided with external female buckles 11, and the external female buckles 11 on the left and right sides are both inclined inwardly arranged; the outer side walls on the left and right sides of the upper cover 2 are both inwardly recessed with buckle grooves 20, the shape and position of the buckle grooves 20 are adapted to the shape and position of the external female buckle 11, the external female buckle 11 is provided with a buckle hole 10, and the buckle groove 20 is provided with an external male buckle 21 adapted to the position of the buckle hole 10; the external female buckle 11 is embedded in the buckle groove 20 on the corresponding side, and the external male buckle 21 is snapped into the buckle hole 10, so that the upper cover 2 is arranged on the top of the bottom shell 1;

[0028] The bottom shell 1 and the upper cover 2 are combined to form a receiving cavity, and the upper cover 2 is provided with a communicating notch 22 communicating with the receiving cavity.

[0029] The LED power supply housing is provided with a bottom shell 1 and an upper cover 2, which are connected by snapping by an external female buckle 11 and a snapping groove 20. Compared with the existing method of fixing by screws or fixing by snapping internally, the connection structure of the bottom shell 1 and the upper cover 2 is arranged on the outside, which effectively utilizes the internal space of the accommodating cavity and increases the layout space of the internal components. At the same time, the production mold structure of the LED power supply housing can be simplified, the mold manufacturing cost can be reduced, and the assembly and repair of the bottom shell 1 and the upper cover 2 can be facilitated.

[0030] The external female buckle 11 is tilted inward, and the buckle slot 20 is also provided with an inclined surface that matches the tilt angle of the external female buckle 11. The two external female buckles 11 cooperate to clamp the upper cover 2, preventing the external female buckle 11 from deforming after multiple assemblies and causing the buckle to not be fastened. At the same time, the inclined surface of the buckle slot 20 has a guiding function, which is convenient for assembly.

[0031] Specifically, the external female buckle 11 is inclined inwardly at an angle of 30 to 60°. In a specific embodiment of the utility model, the external female buckle 11 is inclined inwardly at an angle of 30 to 60°. When the inward inclination angle is too large, the distance between the tops of the two external female buckles 11 is too small. During assembly, the external female buckle 11 needs to be pried apart with force so that the distance between the tops of the two external female buckles 11 increases before the upper cover 2 can be buckled on the bottom shell 1, which is inconvenient for the assembly of the upper cover 2. If the inward inclination angle is too small, the purpose of clamping the upper cover 2 cannot be achieved.

[0032] Specifically, the outer front and rear ends of the external female buckle 11 are both provided with guide slopes 111. With the above structure, the thickness of the front and rear ends of the external female buckle 11 is reduced, so that the external female buckle 11 can be easily opened outward during assembly, reducing the difficulty of assembly.

[0033] Specifically, a disassembly notch 201 is provided at the top of the buckle slot 20 , and an extension plate 112 extends upward from the upper edge of the external female buckle 11 ; when the external male buckle 21 is snapped into the buckle hole 10 , the extension plate 112 is embedded in the disassembly notch 201 .

[0034] The disassembly notch 201 is connected to the buckle groove 20. When the external male buckle 21 is buckled into the buckle hole 10, the extension plate 112 is embedded in the disassembly notch 201. When the bottom shell 1 and the upper cover 2 need to be disassembled, the staff can use the extension plate 112 to pry apart the external female buckle 11, so that the external female buckle 11 is bent outward, so that the buckle hole 10 is away from the external male buckle 21, and the upper cover 2 can be pulled out of the bottom shell 1. The above structure is convenient for staff to disassemble.

[0035] Specifically, a plug plate 23 extends downward from the bottom of the upper cover 2, and the plug plate 23 is arranged along the bottom edge of the upper cover 2. The inner side wall of the bottom shell 1 is provided with a mounting notch 12 that matches the shape of the plug plate 23; when the upper cover 2 is placed on the top of the bottom shell 1, the plug plate 23 is inserted into the mounting notch 12. The above structure enhances the connection stability between the upper cover 2 and the bottom shell 1, making the connection between the upper cover 2 and the bottom shell 1 more secure, and increases the sealing of the accommodating cavity.

[0036] Specifically, the front and rear sides of the bottom shell 1 are both provided with fixing plates 13, and the fixing plates 13 are provided with through holes 131. With the above structure, the LED power supply housing can be fixed to a preset position by cooperating with screws through the through holes 131 of the fixing plates 13, and the structure is simple, which is convenient for workers to fix the LED power supply housing.

[0037] Optionally, a support bar 14 is provided inside the bottom shell 1 for supporting the electronic components. With the above structure, the support bar 14 inside the bottom shell 1 can provide an additional fixing point to firmly fix the electronic components on the bottom shell 1 to prevent the components from loosening or falling off during use. In addition, the bottom shell 1 can reduce the impact and vibration of the electronic components by absorbing and dispersing external impact forces, provide a certain degree of shock resistance and protection, and reduce the risk of component damage.

[0038] The utility model also provides an LED power supply, including a PCB board 3 and the above-mentioned LED power supply housing, wherein the PCB board 3 is arranged in the accommodating cavity, and the PCB board 3 is provided with a line socket 31, and the line socket 31 is electrically connected to the outside through the connecting notch 22.

[0039] The LED power supply adopts the above-mentioned LED power supply housing, and realizes snap connection through the external female buckle 11 and the snap groove 20. Compared with the existing method of fixing by screws or internal snap fixing, the connection structure of the bottom shell 1 and the upper cover 2 is arranged on the outside, which effectively utilizes the internal space of the accommodating cavity and increases the layout space of the internal components. At the same time, the production mold structure of the LED power supply housing can be simplified, the mold manufacturing cost can be reduced, and the assembly and repair of the bottom shell 1 and the upper cover 2 can be facilitated.

[0040] In addition, the line socket 31 on the PCB board 3 is electrically connected to the outside through the connecting notch 22, which saves the internal PCB layout space and is conducive to the expansion of product functions.

[0041] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
