Description

Technical Field

[0001] This utility model relates to the field of spliced ​​printed circuit board technology, and more specifically, it relates to a spliced ​​printed circuit board. Background Technology

[0002] In the technological evolution of electronic engineering and printed circuit board manufacturing, spliced ​​printed circuit boards, as a basic component for flexibly configuring electronic systems, have always been the focus of industry research in terms of design optimization and application innovation. However, looking at the current state of technology, it must be admitted that there are still many technical pain points that need to be solved in terms of the practicality, convenience and reliability of circuit board splicing systems. These problems seriously restrict the further development and popularization of modular electronic devices.

[0003] From a process perspective, the splicing operation of printed circuit boards in existing technologies is generally complex and cumbersome. Traditional splicing methods mainly rely on welding and bolt fixing. Although these technical paths have their advantages in different application scenarios, they all have obvious drawbacks: welding connections, while having high mechanical strength and electrical reliability, require specialized welding equipment, constant temperature soldering irons, flux, and specific solders. This places high demands on the operator's technical skills, and the quality of solder joints is difficult to standardize and control. Moreover, once the connection is completed, the disassembly process often causes irreversible damage to the circuit board. Bolted connections, while offering good disassembly, require the use of screwdrivers, wrenches, and torque-controlled tools to complete a standard splicing, limiting their application in microelectronic devices or space-constrained scenarios. This complex operation process not only significantly reduces production and maintenance efficiency but also significantly increases labor costs and equipment downtime. Especially in large-scale production or on-site emergency repair scenarios, this inefficient splicing method may lead to production line delays or service interruptions, causing serious economic losses. More importantly, traditional splicing methods often cannot achieve rapid disassembly and reassembly, severely limiting the flexibility and upgradeability of modular electronic systems.

[0004] It is worth noting that some innovative designs do attempt to address the ease of circuit board splicing through quick-connect mechanisms. These technological innovations have simplified the splicing and disassembly of circuit boards to some extent, improved operational convenience, and reduced reliance on specialized tools and techniques. However, these quick-connect mechanisms generally suffer from insufficient stability and poor reliability. First, most quick-connect structures lack redundant design and failure protection mechanisms. These simple connections often cannot simultaneously ensure mechanical strength and electrical performance, and are prone to poor contact or momentary disconnection in vibration environments, leading to unstable circuit operation and reduced long-term reliability. More seriously, in mobile devices or industrial applications, circuit boards are frequently subjected to unexpected mechanical shocks or vibrations. These external factors can easily cause the simple connection mechanism to unlock unexpectedly, resulting in loose connections or even complete separation between circuit boards. Once the circuit board splicing fails, it will not only cause immediate interruption of device function but may also trigger a series of chain reactions, such as signal interference, power abnormalities, or even component burnout, causing irreparable damage to the entire electronic system and greatly reducing the lifespan and long-term reliability of the equipment.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a spliced ​​printed circuit board, which has the following advantages:

[0018] 1. The quick-connect device creatively solves the core pain point of cumbersome printed circuit board (PCB) splicing operations in the field of electronic engineering through the ingenious cooperation of quick-connect sleeve, quick-connect rod, quick-connect slot, and adapter rod. The device's clever design features a spiral quick-connect slot on the outside of the quick-connect rod, forming a precise motion transmission system with the adapter rod on the side wall of the quick-connect sleeve. Users only need to rotate or pull the quick-connect sleeve to drive the adapter rod to move smoothly along the spiral trajectory, achieving rapid connection and disconnection of the PCB. It completely eliminates the need for professional soldering equipment, constant-temperature soldering irons, screwdrivers, or wrenches. This innovative design completely eliminates the irreversibility of soldering operations and the complexity of bolted connections in traditional PCB splicing, maintaining the high efficiency and convenience of the splicing process. In particular, the movable spring and movable plate design on the inner side of the quick-connect sleeve provide appropriate pre-tightening force for the entire connection system, ensuring a tight fit between the splicing board and the PCB, preventing loosening and poor contact during use. This efficient and convenient quick-connect device significantly improves the maintenance efficiency and modular flexibility of electronic equipment, making it particularly suitable for large-scale production environments and on-site emergency repair scenarios, effectively saving labor costs and equipment downtime.

[0019] 2. The locking mechanism cleverly solves the key problem of insufficient stability in existing quick-connect systems through the coordinated work of the reset block, connecting block, reset plate, reset hole, locking plate, reset groove, adapter, longitudinal rod, reset spring, and adapter groove. This mechanism employs a multi-redundant safety design: First, the inner end of the adapter rod precisely engages with the adapter groove to form the first mechanical lock; second, the inner wall of the adapter limits the outer end of the adapter rod, forming the second layer of protection; third, the longitudinal rod, in conjunction with the locking plate, locks the adapter in a specific position, forming the third layer of protection. This multi-level protection design ensures that the entire locking system maintains high stability under vibration and mechanical impact, effectively preventing circuit instability and poor contact problems. The ingenious design of the reset plate and reset hole is particularly noteworthy. This design creates a security mechanism that requires a specific sequence of operations to unlock, eliminating the possibility of accidental unlocking due to external factors and preventing the risk of loosening or even complete separation of the circuit board connections. In addition, the reset rod on one side of the reset block and the through-hole design in the connecting block further enhance the stability of the locking mechanism, ensuring that it maintains a precise movement trajectory and locking effect even after long-term use. This highly reliable locking design avoids the risk of cascading failures such as signal interference, power abnormalities, and even component burnout, significantly improving the safety and reliability of the spliced ​​printed circuit board in various harsh working environments, extending the service life of electronic equipment, reducing maintenance costs, and providing a solid guarantee for the stable operation of modular electronic systems.

[0029] Please see Figures 1-5A type of splicing printed circuit board 1 includes a circuit board 1, a splicing plate 2 on one side of the circuit board 1, and mounting holes 3 on both the splicing plate 2 and the circuit board 1. A quick-clamping device is provided on one side of the splicing plate 2, the quick-clamping device including a quick-clamping sleeve 4, a quick-clamping rod 5, a quick-clamping groove 6, and an adapter rod 7. The quick-clamping sleeve 4 is detachably sleeved on the outside of the quick-clamping rod 5, the quick-clamping groove 6 is spirally formed on the outside of the quick-clamping rod 5, and multiple adapter rods 7 are slidably installed on the side wall of the quick-clamping sleeve 4 along a spiral array. A locking mechanism is provided on the outside of the quick-clamping rod 5, the locking mechanism including a reset block 8, a connecting block 9, a reset plate 10, a reset hole 11, a clamping plate 12, a reset groove 13, and an adapter rod 7. The set includes a matching 14, a vertical rod 15, a reset spring 16, and an adapter slot 17. The reset block 8 is fixedly installed on one side of the reset plate 10, the connecting block 9 is fixedly installed on the outside of the quick-release sleeve 4, the reset plate 10 is rotatably installed on the outside of the quick-release sleeve 4, the reset hole 11 is opened at one end of the reset slot 13, the locking plate 12 is fixedly installed on the vertical rod 15, the reset slot 13 is opened on the reset plate 10, the adapter 14 is set on the outside of the quick-release sleeve 4, the vertical rod 15 is fixedly installed on one side of the adapter 14, the two ends of the reset spring 16 are connected to the reset block 8 and the connecting block 9 respectively, and multiple adapter slots 17 are opened in the quick-release slot 6, and one end of the adapter rod 7 is inserted into the adapter slot 17.

[0030] In this embodiment, when the assembled circuit board 1 needs to be disassembled, the reset plate 10 is first rotated clockwise. The reset plate 10 will cause the reset hole 11 and the reset slot 13 to rotate clockwise, and the reset plate 10 will also cause the reset block 8 installed on one side to rotate clockwise. Then, the reset block 8 will cause the reset rod 21 connected on one side to move along the through hole 22, and the reset block 8 will cooperate with the connecting block 9 to press the reset spring 16. When the reset spring 16 is pressed to its limit, the reset hole 11 will just rotate to a position concentric with the card plate 12, and then the adapter will be pushed. The sleeve 14 allows the adapter 14 to slide along the slide rail 20 and the slide groove 19. The adapter 14 will drive the longitudinal rod 15 and the locking plate 12 to gradually slide through the reset hole 11. At the same time, the adapter 14 and the reset plate 10 cooperate to compress the spring 18. When the spring 18 is compressed to its limit, the locking plate 12 near the adapter 14 just completely passes through the reset hole 11 and moves to the other side of the reset plate 10. At this time, the reset plate 10 is released, the reset spring 16 pushes the reset block 8 to rotate in the opposite direction, and then the reset block 8 drives the reset rod 21 to rotate in the opposite direction along the through hole 22. The reset block 8 moves to the reset plate 10, causing the reset groove 13 and reset hole 11 to reverse, so that the longitudinal rod 15 is in the reset groove 13. At this time, the longitudinal rod 15, together with a locking plate 12 near the adapter 14, limits the adapter 14 to one side of the reset plate 10, so that the inner wall of the adapter 14 no longer limits the outer end of the adapter rod 7. Then, the quick-release sleeve 4 and quick-release rod 5 are pulled to both sides, so that the quick-release sleeve 4 drives multiple adapter rods 7 to move. Then, the inner wall of the adapter groove 17 presses the inner end of the adapter rod 7. The rounded corners at the edge and the end of the adapter rod 7 are designed so that one end of the adapter rod 7 slides out of the adapter groove 17, and the other end of the adapter rod 7 will drive the adapter spring 23 to stretch outward. Then the movable spring 24 resets and pushes the movable plate 25, causing the quick-release sleeve 4 and quick-release rod 5 to separate. At the same time, continue to pull the quick-release sleeve 4 and quick-release rod 5 to both sides so that the quick-release rod 5 and quick-release sleeve 4 are removed. Then, follow the above steps to remove the other quick-release sleeves 4 and quick-release rods 5. Then, remove the splicing plate 2 from one side of the circuit board 1 to realize the separation of the circuit boards 1.

[0031] Please see Figures 3-5 As a further implementation of the overall equipment: a spring 18 is connected to one side of the adapter 14, the spring 18 is movably sleeved on the outside of the longitudinal rod 15, and the other end of the spring 18 is in contact with the reset plate 10.

[0032] The inner side of the fitting 14 has a groove 19, and the outer side of the quick-release sleeve 4 is fixed with a slide rail 20. The groove 19 and the slide rail 20 are compatible.

[0033] A reset rod 21 is fixedly connected to one side of the reset block 8, and a through hole 22 is opened in the connecting block 9. One end of the reset rod 21 slides through the through hole 22.

[0034] The quick-release sleeve 4 has an adapter spring 23 on its outer side, and one end of the adapter rod 7 is movably connected to the outer wall of the quick-release sleeve 4 through the adapter spring 23.

[0035] A movable spring 24 is provided on the inner side of the quick-release sleeve 4, and the movable spring 24 is movably sleeved on the outer side of the quick-release lever 5.

[0036] Movable plates 25 are fixedly connected to both ends of the movable spring 24.

[0037] Both the end of the adapter rod 7 and the inner edge of the adapter groove 17 are designed with rounded corners.

[0038] More specifically, when it is necessary to splice circuit boards 1, firstly, the splicing plate 2 is attached to one side of one of the circuit boards 1, and the mounting hole 3 on one side of the circuit board 1 is aligned with the mounting hole 3 on the splicing plate 2. Then, the quick-clamp rod 5 passes through the mounting hole 3 on the circuit board 1 and the splicing plate 2 from one side. Then, the quick-clamp sleeve 4 is fitted onto the outside of the quick-clamp rod 5 from the other side, causing the quick-clamp sleeve 4 to move multiple adapter rods 7. Then, one end of the multiple adapter rods 7 enters the quick-clamp groove 6, and the outer end of the adapter rod 7 at this time drives the adapter spring 23 to stretch outward. Then, the quick-clamp sleeve 4 is rotated forward, and the quick-clamp sleeve 4 drives the multiple adapter rods 7 to slide along the spirally opened quick-clamp groove 6. When the adapter rod 7 moves to the position corresponding to the adapter slot 17 in the quick-release slot 6, the adapter spring 23 resets and pulls the adapter rod 7 to slide inward, so that the inner end of the adapter rod 7 is inserted into the corresponding adapter slot 17. When the quick-release sleeve 4 and the quick-release rod 5 press and fix the splicing plate 2 and the circuit board 1 together again, the adapter rod 7 moves to the position corresponding to the original adapter slot 17. At this time, the adapter spring 23 resets and pulls the adapter rod 7 to slide inward, so that the inner end of the adapter rod 7 is reinserted into the original adapter slot 17. At this time, the quick-release sleeve 4 and the quick-release rod 5 cooperate to press the movable spring 24 through the two movable plates 25. Then, the reset plate 10 is rotated forward again, so that the reset plate 10 drives the reset hole 1. 1. The reset plate 10 rotates clockwise again, and the reset block 8 on one side rotates clockwise again. The reset block 8 then drives the reset rod 21 to slide forward along the through hole 22, so that the reset block 8 and the connecting block 9 cooperate again to press the reset spring 16 sleeved on the outside of the reset rod 21. When the reset hole 11 rotates to the position corresponding to the clamping plate 12, the spring 18 resets and pushes the adapter 14 to slide and reset along the slide rail 20 and the slide groove 19. The adapter 14 will drive the two clamping plates 12 to slide and reset through the vertical rod 15. When the spring 18 is fully reset, the clamping plate 12 at the top of the vertical rod 15 moves back to the original side of the reset plate 10. Then the reset plate is released again. 10. The reset spring 16 pushes the reset block 8 to rotate and reset. Then, the reset block 8 drives the reset rod 21 to slide and reset in the opposite direction along the through hole 22. Then, the reset block 8 drives the reset groove 13 and the reset hole 11 to rotate and reset to a position that does not correspond to the longitudinal rod 15 and the locking plate 12 through the reset plate 10. At this time, the longitudinal rod 15 cooperates with the top locking plate 12 to limit and support the adapter 14 to one side of the reset plate 10, so that the adapter 14 cannot slide. The inner wall of the adapter 14 limits the outer end of the adapter rod 7, so that the adapter rod 7 cannot slide. Then, the adapter rod 7 cooperates with the adapter groove 17 to lock the quick-lock rod 5 and the quick-lock sleeve 4 together to prevent the quick-lock rod 5 and the quick-lock sleeve 4 from moving relative to each other, thereby ensuring the stability of the installation structure.

[0039] In summary, during the use or operation of the overall equipment: when it is necessary to disassemble the assembled circuit board 1, first rotate the reset plate 10 clockwise. The reset plate 10 will drive the reset hole 11 and the reset slot 13 to rotate clockwise, and the reset plate 10 will drive the reset block 8 installed on one side to rotate clockwise. Then, the reset block 8 will drive the reset rod 21 connected on one side to move along the through hole 22, and the reset block 8 will cooperate with the connecting block 9 to press the reset spring 16. When the reset spring 16 is pressed to its limit, the reset hole 11 will just rotate to a position concentric with the clamping plate 12. Then, push the adapter 14 so that it slides along the slide rail 20 and the slide groove 19. The adapter 14 will drive the longitudinal rod 15 and the locking plate 12 to gradually slide through the reset hole 11. At the same time, the adapter 14 and the reset plate 10 cooperate to compress the spring 18. When the spring 18 is compressed to its limit, the locking plate 12 near the adapter 14 just completely passes through the reset hole 11 and moves to the other side of the reset plate 10. At this time, the reset plate 10 is released, and the reset spring 16 pushes the reset block 8 to rotate in the opposite direction. Then the reset block 8 drives the reset rod 21 along the slide rail 20 and the slide groove 19. Hole 22 moves in the reverse direction, and reset block 8 drives reset groove 13 and reset hole 11 to reverse through reset plate 10, so that vertical rod 15 is in reset groove 13. At this time, vertical rod 15, together with a locking plate 12 near adapter 14, limits adapter 14 to one side of reset plate 10, so that the inner wall of adapter 14 no longer limits the outer end of adapter rod 7. Then, quick-release sleeve 4 and quick-release rod 5 are pulled to both sides respectively, so that quick-release sleeve 4 drives multiple adapter rods 7 to move. Then, the inner wall of adapter groove 17 squeezes the inner end of adapter rod 7. The rounded corners at the edge of the wall and the end of the adapter rod 7 are designed so that one end of the adapter rod 7 slides out of the adapter groove 17 and the other end of the adapter rod 7 will drive the adapter spring 23 to stretch outward. Then the movable spring 24 resets and pushes the movable plate 25, causing the quick-release sleeve 4 and quick-release rod 5 to separate. At the same time, continue to pull the quick-release sleeve 4 and quick-release rod 5 to both sides so that the quick-release rod 5 and quick-release sleeve 4 are removed. Then, follow the above steps to remove the other quick-release sleeves 4 and quick-release rods 5. Then, remove the splicing plate 2 from one side of the circuit board 1 to realize the separation of the circuit boards 1.

[0040] When it is necessary to splice circuit boards 1, firstly, attach the splicing plate 2 to one side of one of the circuit boards 1, aligning the mounting hole 3 on one side of the circuit board 1 with the mounting hole 3 on the splicing plate 2. Then, pass the quick-clamp rod 5 through the mounting hole 3 on both the circuit board 1 and the splicing plate 2 from one side. Next, slip the quick-clamp sleeve 4 onto the outside of the quick-clamp rod 5 from the other side, causing the quick-clamp sleeve 4 to move multiple adapter rods 7. Then, one end of each adapter rod 7 enters the quick-clamp groove 6, and the outer end of the adapter rod 7 pulls the adapter spring 23 outward. Then, rotate the quick-clamp sleeve 4 clockwise, causing the quick-clamp sleeve 4 to slide along the spirally opened quick-clamp groove 6. When the adapter rod 7 moves to the position corresponding to the adapter slot 17 in the quick-release slot 6, the adapter spring 23 resets and pulls the adapter rod 7 to slide inward, so that the inner end of the adapter rod 7 is inserted into the corresponding adapter slot 17. When the quick-release sleeve 4 and the quick-release rod 5 press and fix the splicing plate 2 and the circuit board 1 together again, the adapter rod 7 moves to the position corresponding to the original adapter slot 17. At this time, the adapter spring 23 resets and pulls the adapter rod 7 to slide inward, so that the inner end of the adapter rod 7 is reinserted into the original adapter slot 17. At this time, the quick-release sleeve 4 and the quick-release rod 5 cooperate to press the movable spring 24 through the two movable plates 25. Then, the reset plate 10 is rotated forward again, so that the reset plate 10 drives the reset hole 11 and the reset plate 24 to move inward. The slot 13 rotates forward again, and then the reset plate 10 drives the reset block 8 on one side to rotate forward again. The reset block 8 then drives the reset rod 21 to slide forward along the through hole 22, so that the reset block 8 and the connecting block 9 cooperate again to press the reset spring 16 sleeved on the outside of the reset rod 21. When the reset hole 11 rotates to the position corresponding to the clamping plate 12, the spring 18 resets and pushes the adapter 14 to slide and reset along the slide rail 20 and the slide groove 19. The adapter 14 will drive the two clamping plates 12 to slide and reset through the vertical rod 15. When the spring 18 is fully reset, the clamping plate 12 at the top of the vertical rod 15 moves back to the original side of the reset plate 10. Then the reset plate 10 is released again. 0. The reset spring 16 pushes the reset block 8 to rotate and reset. Then, the reset block 8 drives the reset rod 21 to slide and reset in the opposite direction along the through hole 22. Then, the reset block 8 drives the reset groove 13 and the reset hole 11 to rotate and reset to a position that does not correspond to the vertical rod 15 and the locking plate 12 through the reset plate 10. At this time, the vertical rod 15 cooperates with the top locking plate 12 to limit and support the adapter 14 to one side of the reset plate 10, so that the adapter 14 cannot slide. The inner wall of the adapter 14 limits the outer end of the adapter rod 7, so that the adapter rod 7 cannot slide. Then, the adapter rod 7 cooperates with the adapter groove 17 to lock the quick-lock rod 5 and the quick-lock sleeve 4 together to prevent the quick-lock rod 5 and the quick-lock sleeve 4 from moving relative to each other, thereby ensuring the stability of the installation structure.
