With the increasing complexity and diversification of electronic product functions, higher demands are being placed on the flexibility and scalability of integrated circuit boards.

[0003] Traditional circuit board assembly methods mostly rely on screws, soldering, or other mechanical fixing methods. While these methods achieve circuit board connection to a certain extent, they have many shortcomings. For example, although screw fixing is secure, the installation process is cumbersome and requires additional tools and time, which is not conducive to quick assembly and disassembly. Although soldering provides a strong connection, it is difficult to change once completed, lacks flexibility, and may generate thermal stress during the soldering process, affecting the reliability and lifespan of the circuit board. Utility Model Content

[0004] The purpose of this invention is to provide a modular integrated circuit board to address the problem that traditional circuit board assembly methods mentioned in the background art mostly rely on screws, soldering, or other mechanical fixing methods. Although these methods achieve circuit board connection to a certain extent, they have many shortcomings. For example, although screw fixing is stable, the installation process is cumbersome and requires additional tools and time, which is not conducive to rapid assembly and disassembly. Although soldering provides a strong connection, it is difficult to change once completed, lacks flexibility, and may generate thermal stress during the soldering process, affecting the reliability and lifespan of the circuit board.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined integrated circuit board, comprising a circuit board body one and a circuit board body two. An outer plate is fixedly connected to one side of both the top and bottom ends of the circuit board body one. An outer sleeve plate is fixedly connected to one side of both the top and bottom ends of the circuit board body two. A fixing post is fixedly connected to one side of the outer plate. A through groove is formed inside the outer sleeve plate. One side of the fixing post extends through the through groove and outwards to the outside of the outer sleeve plate. Movable slots are formed at the top and bottom ends of one side of the fixing post. Movable plates are arranged inside the movable slots. Trapezoidal limiting blocks are fixedly connected to the opposite sides of the two movable plates, one side of which extends away from the movable plates and outwards to the outside of the fixing post. One end of the trapezoidal limiting block contacts one side of the outer sleeve plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This modular integrated circuit board achieves rapid locking between circuit board body one and circuit board body two through the engagement of the fixing post and the through slot of the outer sleeve plate, and the contact of the trapezoidal limiting block with one side of the outer sleeve plate. During installation, the user simply inserts the fixing post into the through slot; the trapezoidal limiting block automatically retracts inward under external force. Once the fixing post is fully inserted, the trapezoidal limiting block pops outward under the action of the return spring, making tight contact with the outer sleeve plate, thus completing the locking. Disassembly is similar; simply apply external force to retract the trapezoidal limiting block inward to easily separate the circuit board. The entire process requires no additional tools, greatly simplifying installation and disassembly steps and improving work efficiency. The trapezoidal limiting block design not only facilitates installation and disassembly but also… The trapezoidal structure ensures a stable connection between circuit boards, allowing the limiting blocks to generate greater resistance when ejected outwards. This effectively prevents the circuit boards from loosening or separating under external forces. Simultaneously, the elastic force of the return spring further enhances the stability of the connection, maintaining a stable connection between circuit boards even under vibration or impact conditions. This improves the reliability and lifespan of the electronic system. The design of the side end plates on opposite sides of circuit board body one and two, along with the cooperation of the locking plate and slot, ensures precise alignment and positioning of the circuit boards during assembly. The locking design of the limiting slot and the limiting plate further enhances the alignment effect, avoiding performance degradation of the electronic system due to assembly errors.

[0013] 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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a combined integrated circuit board, including a circuit board body 1 and a circuit board body 2. An outer plate 3 is fixedly connected to one side of the top and bottom of the circuit board body 1. An outer sleeve plate 4 is fixedly connected to one side of the top and bottom of the circuit board body 2. A fixing post 5 is fixedly connected to one side of the outer plate 3. A through groove 6 is opened inside the outer sleeve plate 4. One side of the fixing post 5 extends through the outside of the through groove 6 and extends to the outside of the outer sleeve plate 4. Movable grooves 7 are opened at the top and bottom positions of one side of the fixing post 5. Movable plates 8 are arranged inside the movable grooves 7. Trapezoidal limiting blocks 9 are fixedly connected to the opposite sides of the two movable plates 8. The side of the trapezoidal limiting block 9 away from the movable plate 8 extends through to the outside of the fixing post 5. One end of the trapezoidal limiting block 9 contacts one side of the outer sleeve plate 4.

[0015] The fixed column 5 has sliding grooves 11 on both sides of the movable groove 7. The two sides of the movable plate 8 pass through the two sliding grooves 11 and are slidably connected to the sliding grooves 11. A support rod 12 is fixedly connected to the center of the sliding groove 11. The support rod 12 is sleeved with the movable plate 8 and slidably connected.

[0016] Limiting protrusions 10 are fixedly connected to both sides of the top of the movable groove 7, and the bottom of the limiting protrusions 10 contacts the top of the movable plate 8.

[0017] Side end plate 15 and side end plate 2 are fixedly connected to opposite sides of circuit board body 1 and circuit board body 2, respectively. Side end plate 2 has a slot 17 on one side and a card plate 18 is fixedly connected to one side of side end plate 15. One side of card plate 18 extends into the slot 17 and engages with the slot 17.

[0018] Limiting grooves 19 are provided on one side of the card plate 18 at the top, center and bottom positions. Limiting plates 20 are fixedly connected to the top, center and bottom positions of the card groove 17. One side of the limiting plate 20 extends into the interior of the limiting groove 19 and engages with the limiting groove 19.

[0019] Two movable plates 8, one above the other, are fixedly connected to two sides of each other with a return spring 13. The side of the return spring 13 away from the movable plate 8 is fixedly connected to the bottom of the movable groove 7.

[0020] Two damping rods 14 are fixedly connected to the center position of each of the two movable plates 8 set at the top and bottom. The side of the damping rod 14 away from the movable plate 8 is fixedly connected to the bottom of the movable groove 7.

[0021] Working principle: Align the fixing post 5 of the circuit board body 1 with the through slot 6 of the outer sleeve plate 4 of the circuit board body 2, and slowly push it in. As the fixing post 5 is inserted, the trapezoidal limiting block 9 is squeezed and retracts inward when it encounters the inner wall of the outer sleeve plate 4. The movable plate 8 slides under the guidance of the slide groove 11 and the support rod 12, while compressing the return spring 13. When the fixing post 5 is fully inserted into the through slot 6, the trapezoidal limiting block 9 pops outward under the elastic force of the return spring 13 and makes tight contact with one side of the outer sleeve plate 4 to achieve locking. At this time, the damping rod 14 plays a role in buffering and stabilizing the movement of the movable plate 8, preventing the movable plate 8 from moving too fast or too violently. After locking, push the circuit board body 1 towards the circuit board body 2, so that the side end plate 15 contacts the side end plate 2. As the circuit board approaches, the locking plate 18 gradually enters the slot 17 until it is fully inserted. The limiting groove 19 on the locking plate 18 meets and engages with the limiting plate 20 in the slot 17, further enhancing the connection stability between the circuit boards. When it is necessary to disassemble the circuit board, first squeeze the trapezoidal limiting block 9 outward to make it retract inward, releasing the locking between the fixing post 5 and the outer sleeve plate 4. Then, gently pull out the fixing post 5 to separate the circuit board body 1 from the circuit board body 2. Finally, use external force to separate the locking plate 18 from the slot 17, completing the entire disassembly process.

[0022] In summary, this modular integrated circuit board achieves rapid locking between circuit board body 1 and circuit board body 2 through the cooperation of the fixing post 5 with the through slot 6 of the outer sleeve plate 4 and the contact of the trapezoidal limiting block 9 with one side of the outer sleeve plate 4. During installation, the user only needs to insert the fixing post 5 into the through slot 6, and the trapezoidal limiting block 9 automatically retracts inward under external force. When the fixing post 5 is fully inserted, the trapezoidal limiting block 9 pops outward under the action of the return spring 13, making tight contact with the outer sleeve plate 4, thus completing the locking. During disassembly, similarly, only external force needs to be applied to retract the trapezoidal limiting block 9 inward to easily separate the circuit board. The entire process requires no additional tools, greatly simplifying the installation and disassembly steps and improving work efficiency. The design of the trapezoidal limiting block 9 not only facilitates installation and disassembly but also... The design also ensures a stable connection between the circuit boards. The trapezoidal structure allows the limiting block to generate greater resistance when it pops outward, effectively preventing the circuit boards from loosening or separating under external force. At the same time, the elastic force of the return spring 13 further enhances the stability of the connection, maintaining a stable connection between the circuit boards even under vibration or impact conditions, thus improving the reliability and lifespan of the electronic system. The design of the side end plates 15 and 16 on opposite sides of the circuit board body 1 and circuit board body 2, as well as the cooperation between the card plate 18 and the card slot 17, ensures the precise alignment and positioning of the circuit boards during the assembly process. The snap-fit ​​design of the limiting slot 19 and the limiting plate 20 further enhances the alignment effect, avoiding the problem of performance degradation of the electronic system caused by assembly errors.
