This connection method is not only cumbersome to install and remove, but drilling threaded holes in the finished circuit boards can also damage the internal circuitry of the circuit boards, affecting the normal use of the spliced ​​circuit boards. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a circuit board splicing structure that can quickly connect two adjacent finished circuit boards, making the installation and removal process simpler, without damaging the finished circuit boards, avoiding the situation of damaging the internal circuit by drilling threaded holes, and ensuring that the spliced ​​circuit boards can be used normally.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A circuit board splicing structure includes a first circuit board and a second circuit board, and splicing components used to connect the first circuit board and the second circuit board. Two sets of splicing components are provided, one on the front and the other on the back of the splicing point of the first circuit board and the second circuit board. Each set of splicing components includes a base plate 1 and a base plate 2 symmetrically arranged, a female seat fixed on the base plate 1, and a male seat fixed on the base plate 2. The base plate 1 and the base plate 2 are respectively mounted on the first circuit board and the second circuit board. The female seat has an annular female groove, and the male seat has an annular male groove. A rotating column is rotatably connected to the female seat. An arc-shaped locking block is rotatably connected to the annular female groove. The rotating column is connected to the arc-shaped locking block via a connecting rod. The rotating column can rotate the arc-shaped locking block in the annular female groove into or out of the annular male groove via the connecting rod.

[0006] Furthermore, adhesive layers are provided at the bottom of the first base plate and the second base plate respectively, and the first circuit board and the second circuit board are bonded to the first base plate and the second base plate respectively through the adhesive layers.

[0007] Furthermore, a release paper is provided at the bottom of the adhesive layer.

[0009] Furthermore, the base plate one, base plate two, female seat and female seat are all made of aluminum alloy.

[0010] The beneficial effects of this utility model are:

[0011] In practical applications, during assembly, the rotating posts on the front and back of circuit boards 1 and 2 are screwed on. The rotating posts, through the connecting rod, screw the arc-shaped locking block in the annular female groove into the annular female groove, thus connecting circuit boards 1 and 2. During disassembly, the rotating posts on the front and back of circuit boards 1 and 2 are screwed on. The rotating posts, through the connecting rod, screw the arc-shaped locking block back from the annular female groove into the annular female groove, thus separating circuit boards 1 and 2. This invention can quickly connect two adjacent finished circuit boards, making assembly and disassembly simpler. It also avoids damaging the finished circuit boards and prevents damage to the internal circuitry caused by drilling threaded holes, ensuring that the assembled circuit boards can be used normally.

Detailed Implementation

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a circuit board splicing structure includes a first circuit board 1 and a second circuit board 2, which are splicing components used to connect the first circuit board 1 and the second circuit board 2. Two sets of splicing components are provided, one on the front and one on the back of the splicing point between the first circuit board 1 and the second circuit board 2, respectively. Each set of splicing components includes a first base plate 31 and a second base plate 32 symmetrically arranged, a female connector 33 fixed to the first base plate 31, and a female connector 34 fixed to the second base plate 32. The first base plate 31 and the second base plate 32... 32 are respectively installed on circuit board 1 and circuit board 2. The female seat 33 is provided with an annular female groove 331, and the male seat 34 is provided with an annular male groove 341. A rotating column 35 is rotatably connected to the female seat 33. An arc-shaped locking block 36 is rotatably connected to the annular female groove 331. The rotating column 35 is connected to the arc-shaped locking block 36 through a connecting rod 37. The rotating column 35 can rotate the arc-shaped locking block 36 in the annular female groove 331 into or out of the annular male groove 341 through the connecting rod 37.

[0017] During assembly, the rotating posts 35 on the front and back of circuit board 1 and circuit board 2 are screwed on. The rotating posts 35, through the connecting rod 37, screw the arc-shaped locking block 36 in the annular female groove 331 into the annular female groove 341, thus connecting circuit board 1 and circuit board 2. During disassembly, the rotating posts 35 on the front and back of circuit board 1 and circuit board 2 are screwed on. The rotating posts 35, through the connecting rod 37, screw the arc-shaped locking block 36 back from the annular female groove 341 into the annular female groove 331, thus separating circuit board 1 and circuit board 2. This utility model can quickly connect two adjacent finished circuit boards, making the assembly and disassembly process simpler. It also avoids damaging the finished circuit boards and prevents damage to the internal circuitry caused by drilling threaded holes, ensuring that the assembled circuit boards can be used normally.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, adhesive layers 38 are respectively provided on the bottom of the base plate 31 and the base plate 32. The base plate 31 and the base plate 32 are respectively bonded to the circuit board 1 and the circuit board 2 through the adhesive layers 38. In this embodiment, the base plate 31 and the base plate 32 are bonded to the circuit board 1 and the circuit board 2 through the adhesive layers 38. Circuit board 1 and circuit board 2 can be connected without drilling threaded holes on the circuit board, making it easier to install and remove. The adhesive layer 38 uses an organic silicone adhesive, which has good high temperature resistance and can also conduct heat out of the circuit board 1 and the circuit board 2, avoiding excessive temperature at the splice of circuit board 1 and circuit board 2.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a release paper is provided at the bottom of the adhesive layer 38; in this embodiment, the release paper can prevent the adhesive layer 38 at the bottom of the first base plate 31 and the second base plate 32 from sticking together before use, making it more convenient to use.
