[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] See Figures 1 to 4 As shown, an ultra-thin power supply box for track lights includes a base box 1 and a cover 2 fixed by screws. The bottom box has partitions 3 integrally formed at both ends of its recessed cavity, and a drive circuit board 4 is fixed between the two partitions. In this embodiment, the drive circuit board uses a conventional structure from the prior art, simply applied. Furthermore, in this embodiment, the overall height of the base box and cover is only slightly greater than the height of the drive circuit board, thus achieving an ultra-thin effect. The partitions facilitate the installation and positioning of the drive circuit board and allow for sealing by potting adhesive.

[0029] In this embodiment, the cover is provided with a contact slot, and a conductive contact 5 connected to the drive circuit board is provided in the contact slot. In this embodiment, the conductive contact passes through the contact slot and extends out of the cover. When connected to the track, the conductive contact is electrically connected to the conductive strip in the track by pressure.

[0030] In this embodiment, the lid has supports 6 at both ends, and each support has a strip-shaped groove 7. A protrusion 8 is fixed in the middle of the strip-shaped groove. Furthermore, each end of the strip-shaped groove has a retaining member 9, and a first spring 10 is provided between the retaining member and the protrusion. During assembly, the outer end of the retaining member extends outward from the side of the lid under the action of the first spring. To reduce the overall thickness, recessed areas 11 are provided at both ends of the bottom box, located outside the partition. When the lid and bottom box are combined, the supports are located within the recessed areas. This structure not only facilitates installation and connection but also reduces the overall thickness.

[0031] In this embodiment, to improve assembly convenience, a cover plate 12 is fixed to the bottom surface of the support by screws; a second spring 13 is provided on the cover plate, and a circular hole 14 is provided in the middle of the cover plate; the circular hole is mainly used for screw installation, and during assembly, the bottom surface of the conductive contact abuts against the second spring. This structure ensures the elasticity of the conductive contact, thus guaranteeing the effectiveness and stability of its power extraction.

[0032] In this embodiment, a screw post 15 is fixed in the recessed area; the screw passes through the cover and is threadedly fixed to the screw post.

[0033] Meanwhile, in this embodiment, a snap-fit ​​groove 16 is provided in the middle of the inner wall of the bottom box, and a snap-fit ​​protrusion 17 that mates with the snap-fit ​​groove is provided at the bottom edge of the lid; the bottom box and the lid are fixed by screws, and the snap-fit ​​protrusion is engaged in the snap-fit ​​groove for limiting. With the above structure, during assembly, the snap-fit ​​protrusion can be used to position the box first by engaging the snap-fit ​​groove, and then the screws can be installed. The combination of the two methods also helps to improve the stability and reliability of assembly.

[0034] Furthermore, in this embodiment, the symmetrical sidewalls of the fastener are provided with protrusions 18, and the outer edge of the strip groove is provided with a limiting protrusion 19; the outer end of the fastener extends out of the cover under the action of the first spring, and the protrusion abuts against the upper limit of the limiting protrusion. This structure prevents the fastener from loosening or falling out of the strip groove, improving stability and reliability during use.

[0035] This utility model has positive effects: The structure of this utility model is reasonably designed. It has supports at both ends of the lid and recessed areas at both ends of the bottom box. When the two are combined, the thickness of the overall structure can be reduced to achieve an ultra-thin effect. Furthermore, the fastener and the first spring are set in the support, which can reduce the assembly difficulty. The fastener can also ensure the stability and reliability of the installation with the track. It has strong applicability.

[0036] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
