[0025] In the existing design, the driving power box of the lamp usually includes: a power box shell, a driving circuit board installed in the power box shell, and plugs installed at the openings at both ends of the power box shell. The plugs are installed at both ends of the power box shell in a manner that screws pass through the plugs and extend into the power box shell to fix the plugs at the openings at both ends of the power box shell. However, the above scheme not only requires special tools, increases the complexity of assembly, and increases the assembly cost of the driving power box, but also the screws are exposed to the air and are prone to rust, affecting the safety of the power box drive.

[0026] In the present utility model, if Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a driving power supply box, which includes: a power supply box housing 10, and a plug 20, the two ends of the power supply box housing 10 have openings 11, and the plug 20 is installed at the opening 11 to block the opening 11;

[0027] Among them, both sides of the inner wall of the power box shell 10 extend inward along its length direction to form a snap-in groove 12, and the inner side of the plug 20 extends toward the opening 11 to form a fixed convex edge 21. The fixed convex edge 21 extends into the opening 11 and then snaps into the snap-in groove 12, and glue is applied between the fixed convex edge 21 and the inside of the power box shell 10 to fix it.

[0028] In the utility model, the above-mentioned scheme is adopted to overcome the shortcomings of using screws to fix the plug 20, which requires special tools for installation and the screws are easily rusted when exposed to the air, thereby improving the convenience of assembling the power drive box and its own installation safety; moreover, since the clamping groove 12 is provided on the inner wall of the power box shell 10, after the fixed convex edge 21 is clamped in the clamping groove 12, it is prevented that the plug 20 falls off due to the deformation of the power box shell 10.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, specifically, a slot 13 is provided at the bottom of the power box shell 10 along its length direction, and the slot wall of the slot 13 is bent toward the inner wall of the power box shell 10 to form the snap-in slot 12; the fixed convex edge 21 is provided with a clearance notch 211 at a position corresponding to the slot 13, and the two ends of the clearance notch 211 are respectively clamped with the corresponding snap-in slot 12, so as to fix the plug 20 at the openings 11 at both ends of the power box shell 10.

[0030] In order to enable the fixed protrusion 21 to clamp the clamping groove 12, the clearance notch 211 extends toward the inner wall of the fixed protrusion 21 to form a limiting protrusion 212, and the limiting protrusion 212 is embedded in the clamping groove 12. The limiting protrusion 212 abuts against the inner wall of the clamping groove 12, thereby enabling the limiting protrusion 212 to clamp the clamping groove 12.

[0032] The outer diameter of the contraction surface 213 is smaller than the inner diameter of the opening 11, the inner diameter of one end of the guide surface 215 is smaller than the inner diameter of the opening 11, the inner diameter of the other end of the guide surface 215 is smaller than or equal to the inner diameter of the opening 11, and the outer diameter of the interference surface 214 is equal to or slightly larger than the inner diameter of the opening 11, so that the interference surface 214 can extend into the inner side of the opening 11;

[0033] After the contraction surface 213 extends into the opening 11 , the guide surface 215 guides the fixed convex edge 21 to extend into the inner side of the opening 11 , so that the interference surface 214 presses against the inner wall of the power box housing 10 , thereby stably fixing the plug 20 at the opening 11 .

[0034] In order to prevent the plug 20 from completely extending into the power box housing 10 , the plug 20 is further provided with a limiting convex edge 22 corresponding to the opening 11 . The limiting convex edge 22 can abut against the opening 11 to limit the plug 20 from completely extending into the inner side of the opening 11 .

[0035] In order to fix the driving power box, a fixing portion 23 is provided on the outer side of the plug 20, and a fixing through hole 231 is provided on the fixing portion 23. When fixing is required, the screw passes through the fixing through hole 231 and extends into the place where fixing is required, such as the back of the ceiling lamp, or the groove on the back of the linear lamp.

[0036] In order to stabilize the structure of the fixing portion 23 , a reinforcing rib 24 is provided on the inner side of the plug 20 at a position corresponding to the fixing portion 23 . The reinforcing rib 24 can enhance the structural stability of the fixing portion 23 .
