Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0036] In one embodiment of this utility model, such as Figure 1 As shown, a non-isolated power supply box is provided, including a housing 10, a side panel 20, and a top cover 30;

[0037] Both the housing 10 and the side plates 20 are made of aluminum plates. The housing 10 is groove-shaped and consists of a bottom plate and a side wall. The side plates 20 are groove-shaped and consist of a horizontal plate and a side plate. There are two side plates 20, which are embedded in both sides of the housing 10, with the horizontal plate inside and the side plate outside. The top cover 30 has folded edge buckles on both sides and is snapped onto the top of the housing 10. The housing 10 and the top cover 30 work together to make the structure more stable and firm after the side plates 20 are embedded in the housing 10.

[0038] like Figure 2 , 3 As shown, the housing 10 is provided with a side groove 11, a protrusion 12, a curved strip 13, a positioning groove 14, a limiting hole 15, and a nut 16;

[0039] The side groove 11 extends along the housing 10 and is provided on both sides of the housing 10. By providing the side groove 11 on both sides of the housing 10, not only can the heat dissipation effect of the non-isolated power box be improved, but the friction of the power box surface can also be increased, which can effectively prevent the power box from being broken due to slipping. At the same time, it reduces the contact area between the two sides of the housing 10 and the plant light frame, reduces the difficulty of installation, and avoids the problem of the power box sticking to the plant light frame and being difficult to remove during maintenance.

[0040] The protruding strip 12 has a square cross-section and is located on both sides of the housing 10 and above the side groove 11. The outer surface of the protruding strip 12 protrudes from the outer surface of the side wall of the housing 10. The protruding strip 12 causes the side wall of the housing 10 to deform under the pressure of the plant lamp frame, so that the two sides of the housing 10 press against the side plate 20, thereby further improving the structural stability of the power box. At the same time, it also further reduces the contact area between the two sides of the housing 10 and the plant lamp frame.

[0041] The curved strip 13 has a semi-circular arc shape and is located on both sides of the housing 10 and above the protruding strip 12. The curved strip 13 plays a role in cooperating with the top cover 30 to make the top cover 30 and the housing 10 more securely engaged. At the same time, when the top cover 30 and the housing 10 need to be partially engaged, the curved strip 13 acts as a slide rail for the folding buckle plates on both sides of the top cover 30.

[0042] The positioning groove 14 is located at the four corners of the bottom of the housing 10. The positioning groove 14 cooperates with the side plate 20 to restrict the position of the side plate 20.

[0043] The limiting holes 15 are located at both ends of the bottom of the housing 10, and the limiting holes 15 serve to limit the position of the power box within the plant lamp frame.

[0044] The nuts 16 are fixed at both ends of the bottom of the housing 10 and are distributed diagonally. The bottom end of the nuts 16 is polygonal and recessed into the bottom plate of the housing 10. This can increase the connection strength between the nuts 16 and the housing 10, and at the same time ensure that the bottom surface of the housing 10 is flat to facilitate the installation of the power supply box. The nuts 16 serve to fix the side plate 20.

[0045] like Figure 4 , 5 As shown, the side plate 20 is provided with a limiting block 21, a wing edge 22, a connecting ring 23, a heat dissipation groove 24, a mating block 25, and a mating groove 26.

[0046] The limiting block 21 is located at the bottom of the side plate 20. When the side plate 20 is embedded in the housing 10, the limiting block 21 is embedded in the positioning groove 14. The limiting block 21, in cooperation with the positioning groove 14, fixes the side plate 20 in the housing 10. At the same time, it enables the side plate 20 to stand upright in the housing 10 when the power box is assembled.

[0047] The wing edge 22 is located at the bottom of the side of the side plate 20 without a side plate. The wing edge 22 serves to help the side plate 20 stand stably in the housing 10 during installation.

[0048] The connecting ring 23 is located at one end of the wing 22. When the side plate 20 is embedded in the housing 10, the connecting ring 23 is sleeved on the nut 16. The connecting ring 23 plays the role of cooperating with the nut 16 to fix the side plate 20 to the housing 10. At the same time, the connecting ring 23 assists the wing 22 to make the side plate 20 stand stably in the housing 10 during installation.

[0049] The heat dissipation groove 24 is located at the top of the horizontal plate portion of the side plate 21, and the heat dissipation groove 24 serves to better dissipate the heat generated by the power supply.

[0050] The mating block 25 is a hollow structure, located above the wing edge 22, and is fixedly connected to the side plate 21. The mating block 25 serves to mate with the top cover 30 and fix the top cover 30 to the side plate 20.

[0051] The mating groove 26 is provided on the side plate 21 and is located above the mating block 25. The mating groove 26 serves to reserve a position for the installation of the top cover 30.

[0052] like Figure 6 , 7 As shown in Figures 8 and 9, the top cover 30 is provided with a curved groove 31, a top groove 32, a screw hole 33, a protrusion 34, a groove 35, and a wire hole 36.

[0053] The curved groove 31 extends along the top cover 30 and is provided on the inner wall of the folded edge buckle plate on both sides of the top cover 30. When the top cover 30 is fully engaged with the housing 10, the curved groove 31 is sleeved on the outer surface of the curved strip 13. The curved groove 31 plays a role in cooperating with the curved strip 13 to make the connection between the top cover 30 and the housing 10 more stable and firm. At the same time, when assembling the power box, after the top cover 30 and the housing 10 are fully engaged, under the action of the curved groove 31 and the curved strip 13, the folded edge buckle plate of the top cover 30 makes a sound with the side wall of the housing 10 to remind the installer that the top cover 30 and the housing 10 are assembled in place.

[0054] The top groove 32 is located on the top surface of the top cover 30, and the top groove 32 serves to assist in the heat dissipation of the power supply box. The screw holes 33 are located at both ends of the top cover 30. When the top cover 30 is fully engaged with the housing 10, the screw holes 33 are aligned with the holes on the mating block 25. The screw holes 33 serve to fix the top cover 30 to the side plate 20 under the action of screws.

[0055] The screw hole 33 is chamfered to form a protrusion 34 and a groove 35 on the top cover 30. When the top cover 30 is fully engaged with the housing 10, the protrusion 34 is located in the mating groove 26 and contacts the side plate 20. The protrusion 34 restricts the position of the top cover 30 under the action of the side plate 20, and at the same time makes the structure of the side plate 20 in the power box more stable. The groove 35 accommodates the nut when the top cover 30 needs to be tightened with the side plate with screws, so that the top surface of the top cover 30 remains flat.

[0056] The wire hole 36 is located on the top of the top cover 30, and the wire hole 36 serves to allow the power supply wire to pass through the power box. The working principle of this utility model is as follows: A non-isolated power box has two side plates respectively embedded on both sides of the housing 10, with the limiting block 21 embedded in the positioning groove 14 to position the side plate 20. Simultaneously, under the action of the side plate 20's side plate, limiting block 21, wing edge 22, and connecting ring 23, the side plate 20 is stably installed in the housing 10. The top cover 30 is then placed on the housing 10, so that the bottom of the folded edge fastening plate of the top cover 30 contacts the top surface of the protrusion 12, and the folded edge fastening plate of the top cover 30 interacts with the side wall of the housing 10. The sound indicates to the installer that the top cover 30 and the housing 10 are assembled in place. At the same time, with the cooperation of the mating groove 26 on the side plate 20 and the protrusion 34 on the top cover 30, the position of the top cover 30 is completely fixed. The non-isolated power box is assembled and the structure is stable, firm, and easy to disassemble and maintain. If further tightening is required, screws can be installed in the nut 16 to fix the side plate 20 to the housing 10. Then, screws can be installed in the screw hole 33 to allow the screws to enter the mating block 25 and fix the top cover 30 to the side plate 20.

[0057] When the power supply unit requires stronger heat dissipation performance, such as Figure 9 As shown, when the top cover 30 is placed on the housing 10, the bottom of the folded edge buckle plate of the top cover 30 contacts the top of the curved strip 13. With the cooperation of the top cover 30 and the housing 10, the top cover 30 is snapped onto the housing 10, and the non-isolated power box assembly is completed. At this time, the non-isolated power box is still structurally stable and firm, easy to disassemble and maintain. If further tight fixing is required, screws can be installed in the nut 16 to fix the side plate 20 to the housing 10, and screws can be installed in the screw hole 33 to enter the mating block 25 to fix the top cover 30 to the side plate 20.

[0058] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
