Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically a mixed-voltage high-frequency circuit board. Background Technology

[0002] In various electronic devices, such as computers, televisions, telephones, mobile phones, and various control instruments, printed circuit boards are currently used as substrates for fixing components and connecting circuits. Printed circuit boards usually have component holes, fixing holes, and printed circuit lines connecting various component holes on the board body. In use, various high and low voltage and high and low frequency electronic components are inserted and soldered into the component holes of the printed circuit board to form corresponding control circuits. Then, the printed circuit board is fixed to the corresponding electrical housing with its fixing holes to form various electronic devices.

[0003] Some electronic devices have complex circuits, and it is difficult to distribute the required printed circuit lines on a single circuit board. Therefore, multiple circuit boards are often needed for the overall circuit layout.

[0004] Existing multilayer mixed-voltage high-frequency circuit boards are fixed to the integrated mounting frame by multiple threaded components, which means that when disassembling and assembling the circuit board, it is necessary to tighten or loosen multiple threaded components in sequence, making the disassembly and maintenance of the circuit board cumbersome and inefficient. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mixed-voltage high-frequency circuit board. Through the elastic force of a first spring, the top plate supports the bottom of the high-voltage or low-voltage circuit board, ensuring stability and preventing loosening. It can also accommodate circuit boards of different thicknesses, enhancing vibration and impact resistance. Simultaneously, a limiting mechanism limits the sidewalls of the high-voltage or low-voltage circuit board, improving installation stability and reliability. Furthermore, it allows for the independent disassembly of either the high-voltage or low-voltage circuit board, facilitating maintenance and replacement.

[0006] To achieve the above objectives, a mixed-voltage high-frequency circuit board is provided according to an embodiment of the first aspect of this utility model, comprising a mounting frame, a fixing mechanism, and a limiting mechanism. The mounting frame has two mounting slots on its sidewall; a high-voltage circuit board is disposed in the upper mounting slot, and a low-voltage circuit board is disposed in the lower mounting slot. A connecting opening is provided in the middle of the mounting frame, and the bottom of the high-voltage circuit board and the top of the low-voltage circuit board are interconnected. The fixing mechanism includes a top plate and a first spring. A top groove is formed at the bottom of the mounting slots, and the top plate is disposed inside the top groove. One end of the first spring is connected to the bottom of the top groove, and the other end is connected to the bottom of the top plate. The top plate provides elastic support for the bottoms of the high-voltage and low-voltage circuit boards. A first rounded corner is provided on the side of the top plate facing out of the mounting slot. The limiting mechanism is disposed on the sidewall of the mounting slot, limiting the sidewalls of the high-voltage and low-voltage circuit boards that are away from the mounting slot.

[0007] As a further embodiment of this utility model: the limiting mechanism includes a limiting block, a second spring, a limiting rod, and a pull ring. A limiting groove is formed on the side wall of the mounting groove. The limiting block is disposed in the limiting groove. The second spring is disposed between the limiting block and the limiting groove. The limiting rod is disposed on the side of the limiting block facing the limiting groove. The limiting rod passes through the limiting groove and is connected to the pull ring. The limiting rod slides in cooperation with the mounting frame.

[0008] As a further embodiment of this utility model: an elastic block is provided at one end of the mounting groove, and the elastic block provides elastic support for the high voltage circuit board and the low voltage circuit board facing the side wall of the mounting groove.

[0009] As a further embodiment of this utility model, the limiting block has a second rounded corner on the side facing out of the mounting groove.

[0010] As a further embodiment of this utility model: the second spring is sleeved on the limiting rod.

[0011] As a further embodiment of this utility model: the size of the top plate is adapted to the size of the top groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses the elastic force of the first spring to support the bottom of the high-voltage circuit board or low-voltage circuit board with the top plate, ensuring stability and preventing loosening. It can also be adapted to circuit boards of different thicknesses, enhancing vibration and impact resistance. At the same time, the limiting mechanism limits the side wall of the high-voltage circuit board or low-voltage circuit board, improving the stability and reliability of installation. It can also independently disassemble the high-voltage circuit board or low-voltage circuit board, facilitating maintenance and replacement.

[0014] 2. This utility model uses a pull ring to compress the second spring of the limiting block, causing it to quickly retract into the limiting groove, thereby releasing the limiting effect on the circuit board and facilitating disassembly.

[0015] 3. By setting up elastic blocks, this utility model can further improve the stability of the circuit board in the mounting groove, and at the same time prevent the circuit board from shifting or deforming due to vibration or external force, ensuring that the circuit board can maintain the correct position and shape for a long time.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1 to 5 As shown, a mixed-voltage high-frequency circuit board includes a mounting frame 1, a fixing mechanism, and a limiting mechanism. The mounting frame 1 has two mounting slots 11 on its side wall. A high-voltage circuit board 2 is disposed in the upper mounting slot 11, and a low-voltage circuit board 3 is disposed in the lower mounting slot 11. A connecting port 12 is provided in the middle of the mounting frame 1, and the bottom of the high-voltage circuit board 2 and the top of the low-voltage circuit board 3 are interconnected.

[0024] The mixed-voltage high-frequency circuit board employs a design where the high-voltage circuit board 2 and the low-voltage circuit board 3 are interconnected, which optimizes the signal transmission path and reduces signal loss and interference. Especially in high-frequency signal transmission, this design can significantly improve signal transmission efficiency and stability.

[0025] The fixing mechanism includes a top plate 4 and a first spring 42. The bottom of the mounting groove 11 has a top groove 13, and the top plate 4 is disposed inside the top groove 13. The size of the top plate 4 is adapted to the top groove 13. One end of the first spring 42 is connected to the bottom of the top groove 13, and the other end is connected to the bottom of the top plate 4. The top plate 4 provides elastic support for the bottom of the high voltage circuit board 2 and the low voltage circuit board 3. The top plate 4 has a first rounded corner 41 on the side facing out of the mounting groove 11. The design of the first rounded corner 41 can reduce the friction during installation, making the installation process smoother.

[0026] The limiting mechanism is disposed on the side wall of the mounting groove 11 to limit the high voltage circuit board 2 and the low voltage circuit board 3 from the side wall outside the mounting groove 11.

[0027] When the high-voltage circuit board 2 or the low-voltage circuit board 3 is installed in the mounting slot 11, the top plate 4 supports the bottom of the high-voltage circuit board 2 or the low-voltage circuit board 3 by the elastic force of the first spring 42, ensuring that the high-voltage circuit board 2 or the low-voltage circuit board 3 is stable and not easy to loosen. At the same time, it can adapt to circuit boards of different thicknesses, enhancing the vibration and impact resistance. Meanwhile, the limiting mechanism limits the side wall of the high-voltage circuit board 2 or the low-voltage circuit board 3, improving the stability and reliability of the installation, and can independently realize the disassembly of the high-voltage circuit board 2 or the low-voltage circuit board 3, which is convenient for replacement.

[0028] The limiting mechanism includes a limiting block 5, a second spring 53, a limiting rod 52, and a pull ring 54. The side wall of the mounting groove 11 is provided with a limiting groove 14. The limiting block 5 is disposed in the limiting groove 14. The second spring 53 is disposed between the limiting block 5 and the limiting groove 14. The limiting rod 52 is disposed on the side of the limiting block 5 facing the limiting groove 14. The limiting rod 52 passes through the limiting groove 14 and is connected to the pull ring 54. The second spring 53 is sleeved on the limiting rod 52. The limiting rod 52 is slidably engaged with the mounting frame 1.

[0029] When the high-voltage circuit board 2 or the low-voltage circuit board 3 is installed into the mounting slot 11, the sidewall of the circuit board will contact the limiting block 5. As the circuit board is further installed, the limiting block 5 will be squeezed and move into the limiting groove 14, compressing the second spring 53. After the circuit board is installed in place, the reverse elastic force of the second spring 53 will cause the limiting block 5 to extend and press against the sidewall of the circuit board, firmly locking the circuit board in the mounting slot 11. If it is necessary to remove the circuit board, the user can pull the pull ring 54 to retract the limiting block 5 into the limiting groove 14, thereby releasing the limiting of the circuit board.

[0030] An elastic block 6 is provided at one end of the mounting groove 11. The elastic block 6 provides elastic support for the high voltage circuit board 2 and the low voltage circuit board 3 towards the side wall of the mounting groove 11.

[0031] By setting the elastic block 6, the stability of the circuit board in the mounting slot 11 can be improved, and the circuit board can be prevented from shifting or deforming due to vibration or external force, ensuring that the circuit board can maintain the correct position and shape for a long time.

[0032] The limiting block 5 has a second rounded corner 51 on the side facing the outside of the mounting groove 11.

[0033] By setting the second rounded corner 51, the friction between the high-voltage circuit board 2 or the low-voltage circuit board 3 and the limiting block 5 can be reduced, thus improving the smoothness of installation.

[0034] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
