Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lighting component fixing technology. Specifically, this utility model relates to a snap-fit structure for a light source board. Background Technology
[0002] When assembling lighting fixtures, manufacturers mount the light source board onto a bracket. After assembly, the light source board must be stable and precisely positioned, which is crucial for the performance of the lighting fixture. Furthermore, the time spent assembling the light source board determines the overall production cycle of the lamp, thus affecting the cost. Typically, the light source board is attached to the bracket using PCB fasteners or screws, as shown in the diagram. Positioning is achieved through a separate positioning structure on the bracket, followed by screw tightening. However, manual screw tightening by workers reduces production efficiency and carries the risk of electrostatic discharge. For tilted screw posts, demolding issues arise, and complex core-pulling structures are required in the mold, increasing both mold costs and injection molding cycles.
[0003] Chinese patent (publication number: 202442301U) discloses a heat dissipation structure for LED lighting fixtures, including a base, an LED light source board, a reflector, glass, a lamp head ring, a connector, and a spring plate. The base is fixed to the power supply box with screws. The reflector and LED light source board are fixed to the base with screws. The heat generated by the LED is directly conducted to the base and reflector through the LED light source board for heat dissipation, increasing the surface heat dissipation area. The glass is placed on top of the reflector, and the lamp head ring has a platform. One end of the connector is fixed to the base with screws, and the other end is fixed to the lamp head ring and the spring plate with screws. The platform of the lamp head ring presses and fixes the glass on the reflector. However, fixing with screws reduces production efficiency and makes demolding easier. Utility Model Content
[0004] This utility model is designed to solve the aforementioned problems and aims to provide a snap-fit structure for a light source board, which facilitates the assembly of the light source board and reduces production costs. To achieve the above objective, the technical solution adopted by this utility model is as follows:
[0005] A snap-fit structure for a light source board includes a light source board, wherein the light source board is provided with a connecting structure and a first snap-fit that cooperates with the connecting structure.
[0006] The first buckle includes a first connecting plate, and the two ends of the first connecting plate are connected to reinforcing ribs, which are connected to the connecting structure.
[0007] The connection structure includes a connection hole, and the reinforcing rib is located inside the connection hole, with the reinforcing rib abutting against the connection hole.
[0008] A second connecting plate is connected to the first connecting plate, and the second connecting plate abuts against the light source plate.
[0009] The reinforcing ribs and connecting holes are square in shape.
[0010] The first connecting plate, the reinforcing rib, and the second connecting plate are integrally molded polyoxymethylene structures.
[0011] The second connecting plate has a wedge-shaped structure.
[0012] The long side of the connecting hole is 0.1 mm longer than the long side of the reinforcing rib.
[0013] The technical advantages of this invention are as follows: the reinforcing rib engages with the connecting hole, firmly abutting against the side wall of the connecting hole. Through the first connecting plate's own fixed connection with other components, the light source board can be secured. Both the reinforcing rib and the surface of the connecting hole have textured surfaces, which increases the friction between them.
[0014] The first connecting plate, reinforcing rib, and second connecting plate are integrally molded, ensuring the strength and stability of the overall snap-fit structure and preventing loosening of the connections between components during use, which could affect the fixing effect. At the same time, the integral molding process reduces processing steps, improves production efficiency, and lowers production costs. Attached Figure Description

[0017] Figure 2 This is a top view of a snap-fit structure for a light source board according to this utility model.

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.
[0020] like Figures 1-2As shown, a snap-fit structure for a light source board includes a light source board 1, a connecting structure 2 and a first snap-fit 3 that cooperates with the connecting structure 2. The first snap-fit 3 is disposed on a mounting bracket of the light source board 1. The connecting structure on the light source board 1 cooperates with the first snap-fit 3 to fix the light source board 1. After assembly, the light source board 1 will not shake or make any abnormal noise.
[0021] The first buckle 3 includes a first connecting plate 301, with reinforcing ribs 302 connected to both ends of the first connecting plate 301. The reinforcing ribs 302 are connected to the connecting structure 2. The connecting structure 2 includes a connecting hole 201, with the reinforcing rib 302 located inside the connecting hole 201 and abutting against it. The reinforcing rib 302 engages with the connecting hole 201, firmly abutting against the side wall of the connecting hole 201. The first connecting plate 301 itself is fixedly connected to the mounting bracket of the light source plate 1, thus securing the light source plate 1. Both the reinforcing rib 302 and the surface of the connecting hole 201 have textured surfaces to increase the friction between them.
[0022] A second connecting plate 303 is connected to the first connecting plate 301, and the second connecting plate 303 abuts against the light source plate 1. When the second connecting plate 303 abuts against the light source plate 1, the reinforcing rib 302 enters the connecting hole 201 and reaches the designated position.
[0023] The reinforcing rib 302 and the connecting hole 201 are square structures. The reinforcing rib 302 can better fit with the connecting hole 201, the contact area between the reinforcing rib 302 and the connecting hole 201 is larger, and the reinforcing rib 302 has a better fixing ability for the light source plate 1.
[0024] The first connecting plate 301, reinforcing rib 302, and second connecting plate 303 are integrally molded polyoxymethylene (POM). This integral molding structure ensures the strength and stability of the overall snap-fit structure, preventing loosening of connections between components during use and ensuring a secure hold. Furthermore, the integral molding process reduces processing steps, improves production efficiency, and lowers production costs. POM material also offers better wear resistance, reducing wear during insertion and removal.
[0025] The second connecting plate 303 has a wedge-shaped structure. The wedge-shaped structure allows the second connecting plate 303 to undergo a certain elastic deformation when it contacts the light source plate 1 and when it is pressed against the light source plate 1, thereby further enhancing the fit and fixing force between the second connecting plate 303 and the light source plate 1.
[0026] The long side of the connecting hole 201 is 0.1mm longer than the long side of the reinforcing rib 302. This ensures that the reinforcing rib 302 can be smoothly inserted into the connecting hole 201, and also ensures that the reinforcing rib 302 fits tightly against the side wall of the connecting hole 201 after insertion. Through this slight interference fit, the connection reliability between the snap-fit structure and the light source board 1 is enhanced, effectively preventing the snap-fit from loosening due to vibration or other factors, and ensuring that the light source board 1 maintains a stable installation state during use. In addition, during actual assembly, this 0.1mm dimensional difference will not cause excessive obstacles to the installation operation. Workers can easily install the first snap-fit 3 onto the connecting structure 2 of the light source board, balancing assembly convenience and connection firmness.
[0027] The role and effect of the embodiments
[0028] The reinforcing rib 302 engages with the connecting hole 201, firmly abutting against the side wall of the connecting hole 201. Through the first connecting plate 301 itself and its fixed connection with other components, the light source plate 1 can be secured. Both the reinforcing rib 302 and the surface of the connecting hole 201 have textured surfaces to increase the friction between them.
[0029] The first connecting plate 301, the reinforcing rib 302, and the second connecting plate 303 are integrally molded, which ensures the strength and stability of the overall structure of the buckle and prevents the fixing effect from being affected by loosening of the connection between the parts during use. At the same time, the integral molding process reduces processing steps, improves production efficiency, and reduces production costs.
[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
