[0002] A lamp is a common lighting and decorative structure, which generally has a corresponding driver box, which contains a driver circuit board, and the driver circuit board is provided with an input circuit, a transformer circuit, a control circuit and a driver circuit. The main body of the transformer circuit is a transformer. In the prior art, the electronic components of each circuit are plug-in and welded fixed. Although it can meet the general usage requirements, it requires packaging and there will be pins, which makes the overall driver circuit board taller. Moreover, the plug-in terminal of its input circuit generally includes a terminal shell and a conductive plug in the shell. When it is combined with the driver box, due to the existence of the shell, the thickness of the driver box will be larger, and it is difficult to make it thinner, which will also affect its scope of application and limit its practicality.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example

[0019] See Figures 1 to 3 As shown, an ultra-thin driving circuit structure includes a bottom box 1, a cover 2, and a driving circuit board 3. Several electronic components 4 and plug-in terminals 5 are soldered to the driving circuit board via SMD soldering. In this embodiment, the bottom box and the cover are both made of insulating plastic, aluminum, or stainless steel. The electronic components, including resistors, capacitors, transformers, or connecting terminals, are all fixed by SMD soldering, thereby reducing the overall thickness of the driving circuit board and electronic components, achieving an ultra-thin effect.

[0020] Furthermore, in actual use, the plug-in terminal includes a pin support plate 51 and at least two conductive pins 52 fixed to the pin support plate. The inner ends of the conductive pins are soldered to the driver circuit board. The height of the pin support plate only needs to be slightly larger than the diameter of the conductive pins, and there is no need to add a shell around the edges of the conductive pins, thereby reducing the thickness of the overall structure. Furthermore, the edges of the bottom box and the top cover are each provided with a plurality of semicircular grooves 6. During assembly, the bottom box and the top cover are fixedly connected, and the semicircular grooves are combined to form a complete circular hole, into which the conductive pins of the plug-in terminal extend. In other words, in actual use, the inner wall of the circular hole serves as the shell of the conductive pins, thereby reducing the use of the pin shell, reducing costs, and also helping to reduce the thickness of the overall structure, achieving an ultra-thin effect and strong practicality.

[0021] Furthermore, in actual use, the pin support plate is shorter than the inner height of the base box and the front cover. The pin support plate is made of insulating plastic. It contains two conductive pins. This structure ensures that the pin support plate does not affect the overall thickness of the structure or the assembly connection between the base box and the front cover, enhancing practicality.

[0022] The present invention has positive effects: the structure of the present invention is reasonably arranged, and its electronic components are all soldered on the driver circuit board, so that there are no pins, which makes the thickness of the entire driver circuit board thinner, and its plug-in terminals include pin support plates and conductive posts, which do not have corresponding conductive post shells. They cooperate with the semicircular grooves on the bottom box and the surface cover, that is, the semicircular grooves are used as the shells of the conductive posts, thereby reducing the overall thickness of the bottom box and the surface cover, achieving an ultra-thin effect, and being stable and reliable to use, and having strong practicality.

[0023] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0024] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
