[0002] In the field of electronic equipment manufacturing, the assembly process of PCBA motherboards directly affects the production efficiency and quality stability of products. Traditional fixing methods mainly include screw fastening, clip fixing, and guide rail installation. These methods generally suffer from low assembly efficiency, insufficient fixing reliability, or lack of error prevention mechanisms. For example, screw fastening requires tightening each screw individually, which is cumbersome; clip structures are prone to aging and loosening; and guide rail installation requires high machining precision and is difficult to achieve quick locking. Furthermore, users may forget to tighten the screws after assembling the motherboard, which is difficult to detect later and affects usability. These defects make the motherboard assembly process time-consuming and labor-intensive, and may affect the long-term reliability of the equipment. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0020] Please see Figure 1-4In this utility model, a PCBA motherboard that is easy to assemble includes a mounting base plate 1, a mounting slot 2, and a motherboard body 3. The mounting slot 2 is located on the top of the mounting base plate 1, and the motherboard body 3 is located inside the mounting slot 2. The top of the mounting base plate 1 has evenly distributed movable slots 4. A mounting seat 5 is slidably connected to the inner wall of the movable slot 4. A synchronous shaft 6 is slidably connected inside the mounting seat 5. Two limiting slots 7 are provided on the inner wall of the movable slot 4. The bottom end of the synchronous shaft 6 passes through the mounting seat 5 and is located inside the corresponding limiting slot 7. A synchronous shaft 6 is slidably connected to the inner wall of the mounting seat 5. The synchronous shaft 6 is rotatably connected to the synchronous plate 8. A spring 9 is fixedly installed on the top of the synchronous plate 8. The top of the spring 9 is connected to the inner wall of the mounting base 5. A protective cover 10 is detachably connected to the top of the mounting base 1. The protective cover 10 has evenly distributed through slots 11. The top of the synchronous shaft 6 passes through the through slots 11 and extends to the top of the protective cover 10. A rotating clamping plate 12 is fixedly installed on the top of the synchronous shaft 6. The bottom of the rotating clamping plate 12 contacts the protective cover 10. A limiting plate 13 is rotatably connected to the synchronous shaft 6. The limiting plate 13 is located on the top of the main body 3.

[0021] Two guide shafts 14 are fixedly connected to the bottom of the limiting plate 13, and the bottom ends of the guide shafts 14 penetrate through and extend into the interior of the mounting base 5;

[0022] A guide groove 18 is provided on the inner wall of the movable groove 4, and the mounting base 5 is slidably connected to the inner wall of the guide groove 18.

[0023] When PCBA motherboard assembly is required, the operator first pulls the synchronous shaft 6 upward. At this time, the synchronous plate 8 compresses the spring 9 under the drive of the synchronous shaft 6, so that the bottom end of the synchronous shaft 6 is disengaged from the limiting groove 7. Then, the mounting base 5 slides outward along the movable groove 4. The limiting plate 13 is completely moved out of the area above the mounting groove 2 by the guide groove 18. At this time, the motherboard body 3 can be accurately placed into the mounting groove 2.

[0024] After placing the motherboard body 3, pull up the synchronous shaft 6 again to completely disengage it from the limiting groove 7. Push the mounting base 5 inward to move the limiting plate 13 directly above the motherboard body 3. After releasing the synchronous shaft 6, under the elastic force of the spring 9, the synchronous shaft 6 automatically snaps into the inner limiting groove 7. At this time, the limiting plate 13 stably presses the motherboard body 3 under the guidance of the guide shaft 14, achieving reliable fixation.

[0025] When installing the protective cover 10, the rotating plate 12 should be aligned with the through slot 11 first, and then the protective cover 10 should be pressed down. After the rotating plate 12 has completely passed through the through slot 11, the protective cover 10 can be locked by rotating. If the limiting plate 13 is not moved to the position above the motherboard body 3, the protective cover 10 will not be fully installed. This design can effectively prevent the motherboard fixing steps from being missed.

[0026] In this invention, the assembly mechanism achieves two precise positioning positions through the cooperation of the limiting groove 7 and the synchronous shaft 6, uses the spring 9 to provide continuous clamping force, and cooperates with the guide shaft 14 to ensure the accuracy of the movement trajectory. The cooperation of the rotating plate 12 and the through groove 11 not only realizes the rapid installation of the protective cover 10, but also forms an error prevention mechanism to ensure that the main board body 3 is reliably fixed before the protective cover 10 is installed. The entire assembly process is simple to operate, and the movement trajectory of each component is clear, which effectively improves the assembly efficiency and reliability of the PCBA main board.

[0027] Please see Figure 1-3 Among them, the bottom of the limiting plate 13 is fixedly connected to the damping pad 15, and the damping pad 15 is in contact with the main body 3.

[0028] In this invention, when the limiting plate 13 limits the main body 3, the damping pad 15 will increase the degree of compression without causing excessive damage to the main body 3, thus avoiding hard contact.

[0029] Please see Figure 1 The protective cover 10 has heat dissipation slots 16 arranged at equal intervals on its top, and the heat dissipation slots 16 are located on the top of the motherboard body 3.

[0030] In this invention, the heat dissipation slot 16 can dissipate heat from the motherboard body 3 inside the protective cover 10 for a long time, preventing heat accumulation from affecting its use.

[0031] Please see Figure 1 The mounting base plate 1 has a finger groove 17 on its top, and the interior of the finger groove 17 is connected to the interior of the mounting groove 2.

[0032] In this invention, when the user needs to remove the motherboard body 3, the finger groove 17 can provide a good point of leverage, avoiding excessive friction between the motherboard body 3 and the inner wall of the mounting groove 2 when it is removed.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
