Description

Technical Field

[0001] This utility model relates to the field of PCB boards, and more particularly to a layered PCB board that is easy to repair. Background Technology

[0002] With the continuous development of electronic technology, traditional multilayer PCBs, while emphasizing performance and integration during design and manufacturing, often neglect ease of maintenance, leading to complex and time-consuming repair processes. Modern PCBs mostly employ surface mount technology (SMT), which improves production efficiency and reliability, but once soldering defects or component failures occur, repair personnel need to inspect and repair a large number of components, increasing complexity and time costs. Simultaneously, with the increasing automation of industrial equipment, the demand for repairing complex PCBs such as industrial control boards is growing. The rapid development of the repair industry has also prompted manufacturers and designers to pay more attention to the maintainability of PCBs to reduce repair costs and shorten repair time.

[0003] Currently, most of the existing easy-to-repair layered PCBs cannot be quickly removed, which makes it difficult to quickly repair damaged PCBs and increases the difficulty of repair when needed. In order to address this technical problem, this application proposes an easy-to-repair layered PCB. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-maintain layered PCB board, which aims to solve the problem of difficult maintenance in existing easy-to-maintain layered PCB boards.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The easily repairable layered PCB board includes a housing. Multiple sliding grooves are formed on the left side of the housing's interior, and multiple sliding through grooves are formed on the right side of the housing. A mounting plate is slidably connected inside each sliding groove. A slider is fixedly connected to the right side of the mounting plate and slidably connected inside the sliding groove. A storage groove is formed inside the slider, and movable grooves are formed on both the front and rear sides of the inner wall of the storage groove. Positioning components are slidably connected inside both ends of the movable grooves. The top side of the mounting plate is connected to the PCB board via multiple fixing components.

[0007] Furthermore, the positioning component includes a sliding member, which is slidably connected inside the moving grooves at both ends, and a positioning member is fixedly connected to the outer wall of the sliding member.

[0008] Furthermore, the fixing component includes a fixing ring, which is fixedly connected to the outer wall of the PCB board, and a screw is threaded inside the fixing ring.

[0009] Furthermore, the mounting plate has multiple threaded grooves on its top side, the inner wall of the threaded grooves is threaded to the bottom end of the outer wall of the screw, and a spring is provided inside the threaded grooves.

[0010] Furthermore, one end of the spring is fixedly connected to the bottom side of the threaded groove, and the other end is fixedly connected to a pressure block, the top side of the pressure block abutting against the bottom side of the screw.

[0011] Furthermore, a plurality of positioning grooves are provided on the right side of the outer casing, and the positioning grooves are located on the bottom side of the slide groove.

[0012] Furthermore, a door is rotatably connected to the front side of the outer casing, and multiple handles are fixedly connected to the front side of the door.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, after opening the box door, the sliding block can be moved to move the mounting plate and simultaneously remove the PCB board mounted on the top side of the mounting plate from the inside of the shell. Furthermore, by moving and rotating the positioning component, the positioning component can be inserted into the positioning groove to fix the mounting plate, thus achieving the effect of quick repair of the PCB board. This eliminates the need to disassemble the PCB board during repair, thereby reducing the difficulty of PCB board repair.

[0015] 2. In this utility model, when the PCB board is installed by screws, the bottom side of the screw will first contact the pressure block and compress the spring, so that the spring continuously exerts force on the screw through the pressure block, making the threads on the outer wall of the screw fit more tightly with the threads on the inner wall of the spring groove, thereby making the screw more tightly fixed to the fixing ring and the screw.

[0023] 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.

[0024] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an easy-to-maintain layered PCB board, including a housing 1. Multiple sliding grooves are provided on the left side of the interior of the housing 1, and multiple sliding through grooves are provided on the right side of the housing 1. A mounting plate 7 is slidably connected inside the sliding grooves. A slider 4 is fixedly connected to the right side of the mounting plate 7. The slider 4 is slidably connected inside the sliding groove 5. A storage groove is provided inside the slider 4. Moving grooves 13 are provided on both the front and rear sides of the inner wall of the storage groove. Positioning components are slidably connected inside the moving grooves 13 at both ends. A PCB board 8 is connected to the top side of the mounting plate 7 via multiple fixing components. The positioning components include a rotating slider 11, which is slidably connected inside the moving grooves 13 at both ends. A positioning component 12 is fixedly connected to the outer wall of the rotating slider 11. Multiple positioning grooves 6 are provided on the right side of the housing 1, located at the bottom side of the sliding groove 5. A door 2 is rotatably connected to the front side of the housing 1, and multiple handles 3 are fixedly connected to the front side of the door 2.

[0025] Specifically, when PCB board 8 needs repair, first open the box door 2 using handle 3, then move slider 4 to move mounting plate 7 and PCB board 8 on top of mounting plate 7 out of the housing 1. Then move positioning piece 12 and rotate it so that the bottom left side of positioning piece 12 inserts into positioning groove 6, thereby fixing mounting plate 7. This allows for quick repair of PCB board 8, achieving the effect of rapid repair of PCB board 8. This eliminates the need to disassemble PCB board 8 during repair, thus reducing the difficulty of repairing PCB board 8.

[0026] Reference Figure 1 , Figure 2 and Figure 5The fixing component includes a fixing ring 10, which is fixedly connected to the outer wall of the PCB board 8. A screw 9 is threadedly connected inside the fixing ring 10. Multiple threaded grooves are opened on the top side of the mounting plate 7. The inner wall of the threaded groove is threadedly connected to the bottom end of the outer wall of the screw 9. A spring 15 is installed inside the threaded groove. One end of the spring 15 is fixedly connected to the bottom side of the threaded groove, and the other end is fixedly connected to a pressure block 14. The top side of the pressure block 14 abuts against the bottom side of the screw 9.

[0027] Specifically, when installing PCB board 8, first place PCB board 8 on the top side of mounting plate 7, then align the fixing ring 10 with the threaded groove, and then fix the fixing ring 10 with the threaded groove using screw 9. When installing screw 9, the bottom side of screw 9 will first contact the bearing block 14, thereby pressing the bearing block 14 downward. At the same time, the bearing block 14 compresses the spring 15, which in turn causes the spring 15 to continuously apply force to screw 9 through the bearing block 14, making the thread on the outer wall of screw 9 more tightly connected with the thread on the inner wall of the threaded groove, thus making screw 9 more firmly fixed to PCB board 8 and improving the overall stability of PCB board 8.

[0028] Working principle: When installing PCB board 8, first place PCB board 8 on the top side of mounting plate 7, then align the fixing ring 10 with the threaded groove, and then fix the fixing ring 10 with the threaded groove using screw 9. When installing screw 9, the bottom side of screw 9 will first contact the bearing block 14, thereby pressing the bearing block 14 downward. At the same time, the bearing block 14 compresses the spring 15, which in turn causes the spring 15 to continuously apply force to screw 9 through the bearing block 14, making the thread on the outer wall of screw 9 more tightly connected with the thread on the inner wall of the threaded groove, thus making screw 9 more firmly fixed to PCB board 8. When PCB board 8 needs to be repaired, first open the box door 2 using handle 3, then move slider 4, and move mounting plate 7 and PCB board 8 on the top side of mounting plate 7 out of the inside of the outer shell 1. Then move positioning part 12 and rotate it so that the bottom left side of positioning part 12 inserts into the inside of positioning groove 6, thereby fixing mounting plate 7, and thus quickly repairing PCB board 8.
