Description

Technical Field

[0001] This utility model belongs to the field of circuit board technology, specifically relating to a novel frequency conversion circuit board. Background Technology

[0002] Circuit boards are named as follows: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board (copper etching technology), etc. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can also be called printed circuit boards or printed circuit boards, with English names including (Printed Circuit Board) PCB, (Flexible Printed Circuit Board) FPC (also known as flexible circuit board, a highly reliable and highly flexible printed circuit board made of polyimide or polyester film as the substrate, characterized by high wiring density, light weight, thinness, and good bending properties), and rigid-flex board (soft and hard combination plate). The birth and development of FPC and PCB gave rise to this new product, the rigid-flex board. Therefore, a rigid-flex PCB is a circuit board that combines flexible circuit boards and rigid circuit boards through processes such as lamination, according to relevant process requirements, to form a circuit board with both FPC and PCB characteristics.

[0003] A multi-layer circuit board frequency converter disclosed in publication number CN202323136700.7 includes a first circuit board, a second circuit board, a first connector, a second connector, and a connecting plate. The first connector is connected to both the first circuit board and the connecting plate, and the second connector is connected to both the second circuit board and the connecting plate. The first and second circuit boards are distributed in parallel. This design improves the connection strength of the multiple circuit boards in the frequency converter. The aforementioned multi-layer circuit board inverters still have certain drawbacks. The multi-layer inverter circuit board occupies a large space and increases the overall thickness of the circuit board. This may cause installation difficulties for compact devices with limited space (such as portable electronic devices or high-density industrial controllers). Moreover, the circuit boards on both sides are not easy to disassemble after assembly, and maintenance is inconvenient when a fault occurs. Therefore, we propose a new type of inverter circuit board.

[0015] 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.

[0016] Please see Figure 1-3This utility model provides a novel inverter circuit board technical solution: It includes a first circuit board 1 and a second circuit board 2. A first protective frame 3 is fixedly connected to the outside of the first circuit board 1, and a second protective frame 4 is fixedly connected to the outside of the second circuit board 2. A first connecting block 5 is fixedly connected to the front and rear sides of the bottom of the first protective frame 3, and a second connecting block 6 is fixedly connected to the left and right sides. A third connecting block 7 is fixedly connected to the front and rear sides of the bottom of the second protective frame 4, and a fourth connecting block 8 is fixedly connected to the left and right sides. A snap-fit ​​block 9 is fixedly connected to the bottom of the first connecting block 5, and a snap-fit ​​groove 10 is provided on the top of the third connecting block 7. The snap-fit ​​block 9 is adapted to the snap-fit ​​groove 10, and a snap-fit ​​block 9 is movably connected to the front of the snap-fit ​​block 9. Block 11 has a slot 12 inside the snap-fit ​​groove 10, which extends to the outside of the third connecting block 7. The snap-fit ​​block 11 is adapted to the slot 12. The snap-fit ​​block 9 on the first connecting block 5 is inserted into the snap-fit ​​groove 10 in the third connecting block 7, and the snap-fit ​​block 11 is inserted into the slot 12, forming a double limit to ensure the stability after connection. When disassembly is required, the snap-fit ​​block 11 is removed from the slot 12, and the snap-fit ​​block 9 is removed from the slot 10, so that the two circuit boards can be disassembled. This solves the problem of the large space occupied by the multi-layer frequency converter circuit board and the increase in the overall thickness of the circuit board. It can be easily installed in compact equipment with limited space. Moreover, the circuit board is easy to disassemble after assembly, and maintenance is convenient in case of failure.

[0017] Specifically, the snap-fit ​​block 9 has a groove 13 inside, and a spring 14 is installed inside the groove 13. One end of the spring 14 is fixedly connected inside the groove 13, and the other end is fixedly connected to one side of the snap-fit ​​block 11. The snap-fit ​​block 11 is movably connected inside the groove 13. By pressing the snap-fit ​​block 11, the spring 14 extends and retracts, enters the groove 13, and separates the snap-fit ​​block 11 from the snap-fit ​​slot 12. Then, the snap-fit ​​block 9 is separated from the snap-fit ​​slot 10, and the spring 14 rebounds, making the separation of the snap-fit ​​block 11 from the snap-fit ​​slot 12 convenient and quick.

[0018] Specifically, the bottom of the second connecting block 6 is fixedly connected to a limiting rod 15, and the top of the fourth connecting block 8 is provided with a limiting groove 16. There are multiple limiting rods 15 and limiting grooves 16 that are compatible. When connecting two circuit boards, the limiting rod 15 is inserted into the limiting groove 16 to further improve the stability of the connection between the two circuit boards.

[0019] Specifically, both the outer sides of the first protective frame 3 and the second protective frame 4 are provided with anti-slip protrusions. There are multiple anti-slip protrusions. The anti-slip protrusions facilitate the provision of a point of leverage for the circuit board to disassemble the two circuit boards.

[0020] Specifically, after the No. 1 protective frame 3 and the No. 2 protective frame 4 are connected, a vent 17 is formed on the outside. There are multiple vents 17, and heat dissipation between the circuit boards is carried out through the vents 17 to improve the heat dissipation effect.

[0021] Specifically, a baffle 18 is provided on the outside of the third connecting block 7. The baffle 18 is rotatably connected to the outside of the third connecting block 7. After the circuit board is connected, the baffle 18 blocks the connection between the card block 11 and the card slot 12 to prevent dust from entering and improve the dustproof effect.

[0022] In this implementation scheme, when using the circuit board, the snap-fit ​​block 9 on the first connecting block 5 is inserted into the snap-fit ​​slot 10 in the third connecting block 7, and the snap-fit ​​block 11 is inserted into the slot 12 to form a double limit, ensuring the stability of the connection. When disassembly is required, the snap-fit ​​block 11 is removed from the slot 12 and the snap-fit ​​block 9 is removed from the slot 10, so that the two circuit boards can be disassembled. This solves the problem of the large space occupied by the multi-layer frequency converter circuit board and the increase in the overall thickness of the circuit board. It can be easily installed even in compact equipment with limited space. Moreover, the circuit board is easy to disassemble after assembly, and maintenance is convenient in case of failure.
