Description

Technical Field

[0001] This application relates to the technical field of circuit boards, and in particular to an installation structure for an LED lamp circuit board. Background Art

[0002] A circuit board usually has a printed circuit, printed components, or a conductive pattern formed by a combination of both on an insulating material, which is called a printed circuit. Traditional circuit boards have poor seismic resistance and do not have a buffer structure. During transportation or use, vibrations are likely to cause problems such as the detachment of electronic components or damage to the circuit, affecting the service life and performance of the circuit board.

[0003] There are also some circuit boards with buffer structures in the prior art. For example, a Chinese patent with the authorization announcement number CN218831007U and a publication date of April 7, 2023, discloses a circuit board with seismic stability, including a circuit board body, a housing, pin columns, fixing nuts, and buffer springs. The housing has a cavity for placing the circuit board body. A fixing hole is respectively opened at each of the four corners of the housing. A pin column is inserted through the fixing hole, penetrating from the bottom of the housing to the top of the housing. The buffer spring is sleeved on the part of the pin column that penetrates out of the housing. The top end of the pin column has an external thread, and the fixing nut is in threaded cooperation with the pin column. The buffer spring is in a compressed state and is limited between the outer wall of the top of the housing and the fixing nut. Among them, the fixing nut includes an end cap and a fixing column. The fixing column is provided below the end cap. The fixing column is hollow and milled with an internal thread that matches the external thread of the pin column. The surface of the end cap has several screw holes for external fixing

[0004] In the above, connection is achieved by setting pin columns with buffer springs, and fixing is carried out through the pin columns and the fixing nuts to achieve a buffer effect. Regarding the related technology above, the inventor believes that the spring in this application is located on the outside and is prone to friction with the circuit board. Moreover, in the installation process, the pin columns are prone to rotation when using a threaded connection method, affecting the installation effect. Utility Model Content

The buckle cover 102 and the sealing plate 103 in this embodiment are both slidably connected to the mounting shell 1, and buckles are provided at the connection points. A cover plate is snapped with the upper end of the mounting shell 1 (the cover plate is not drawn in the figure); a plurality of mounting holes 201 are provided on the circuit board 2 and a buffer 3 is connected through the mounting holes 201. The buffer 3 is made of elastic material and is connected to the mounting plate 101. Positioning protrusions 301 are provided at the upper and lower ends of the buffer 3, and an elastic member 302 is embedded in the positioning protrusion 301. A positioning hole 101a corresponding to the positioning protrusion 301 is provided on the mounting plate 101.

[0030] Reference Figure 4 and Figure 5, the buffer member 3 is made of rubber material. The buffer member 3 includes a connecting portion 303 in the middle. The connecting portion 303 is cylindrical and an annular groove 303a is provided on the outer side of the connecting portion 303.

When the positioning convex portion 301 is ejected for the first time, the positioning convex portion 301 needs to be pressed back between the mounting plates 101. When the positioning convex portion 301 is ejected for the second time, the positioning convex portions 301 at the four corners of the circuit board 2 correspond to the positioning holes 101a on the two side mounting plates one by one, and the circuit board 2 is stably fixed. Since the buffer member 3 is made of elastic rubber material, and at the same time, buffer convex portions 304 are provided on the buffer member 3 and are connected to the mounting plate through the buffer convex portions 304, it can buffer the circuit board 2, improve the seismic performance of the circuit board 2, and facilitate installation and use.

[0034] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
