[0020] 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.

[0021] Example

[0022] See Figures 1 to 3As shown, an LED driver plug structure is provided at both ends of a driver housing 1, including a U-shaped plug body 2. The U-shaped plug body is placed horizontally, and the long side of the U-shaped plug body is set on the side close to the center line of the driver housing. With the above structure, that is, the protrusion of the U-shaped plug body is located at the edge of the driver housing, so that the C-shaped mounting grooves at both ends of the bottom wall of the driver housing can be exposed, which makes it convenient for the mounting screw to fix the driver housing to the corresponding mounting position.

[0023] In this embodiment, the top surface of the convex-shaped plug is provided with a cavity 3, and the long side of the convex-shaped plug is a hollow side that is connected to the cavity. In this embodiment, the hollow side is mainly to facilitate the end of the drive circuit board to extend into the cavity, and the connecting terminal 7 is located in the cavity and attached to the top surfaces of both ends of the drive circuit board, which is the conventional installation method in the prior art.

[0024] Furthermore, the bottom wall of the cavity has two symmetrically arranged fixing holes 4 around the center line for mounting and fixing to the bottom wall of the drive housing; several supporting ribs 5 are integrally formed on the bottom wall of the cavity; a supporting step 6 for supporting the end edge of the drive circuit board is integrally formed on the symmetrical inner wall of the cavity, and the edge of the supporting step is connected to the edge of the fixing hole; the top surface of the supporting step and the supporting rib are on the same horizontal plane. The fixing holes are mainly used to fix the plug to the bottom wall of the drive housing with bolts, ensuring the stability of the installation position of the U-shaped plug. When the drive circuit board is fixed to the drive housing, the two ends of the supporting rib and the supporting step can abut against the supporting rib and the supporting step, pressing the bottom surface of the U-shaped plug into contact with the bottom wall of the drive housing, preventing it from lifting up. This prevents glue leakage when applying glue and improves the sealing effectiveness.

[0025] In this embodiment, the supporting step protrudes 0.3-0.4mm above the top surface of the fixing hole. Simultaneously, the long side width of the convex-shaped plug matches the internal width of the drive housing. During assembly, the convex-shaped plug is attached to the inside of the drive housing, with its bottom surface adhering to the bottom wall of the drive housing, and its symmetrical sidewalls adhering to the symmetrical inner walls of the drive housing. This ensures a close fit between the convex-shaped plug and the inner wall of the drive housing, guaranteeing the effectiveness of subsequent adhesive application.

[0026] Furthermore, in this embodiment, the convex-shaped plug is a plastic structural component.

[0027] This utility model has the following positive effects: Its structure is rationally designed, employing a U-shaped plug. During assembly, the C-shaped mounting groove on the drive housing can be positioned within the recessed area of ​​the U-shaped plug, and the bottom wall of its recess has fixing holes. This allows for quick and easy installation and fixation to the drive housing using bolts, ensuring stable and reliable installation. Furthermore, it features supporting ribs and steps, so when the drive circuit board is fixed to the drive housing with screws, both ends of the drive circuit board abut against the supporting ribs and steps. This pressure from the drive circuit board prevents the bottom surface of the U-shaped plug from lifting, thus preventing glue leakage during application and improving stability and reliability. It also boasts strong applicability.

[0028] 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.

[0029] 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.
