[0002] The clock machine PCBA board is a printed circuit board assembly for clock machines. It uses a printed circuit board as the basic carrier and integrates various electronic components required for the operation of the clock machine into a whole through processes such as soldering and plugging, forming a module with complete electrical functions. It needs to be fixed during installation.

[0003] For example, Chinese Patent No. CN209363226U discloses a PCBA board positioning mechanism, including a base plate and two positioning plates disposed on the base plate. The base plate is provided with a sliding mechanism that allows the two positioning plates to move horizontally on the surface of the base plate towards opposite or opposite sides. The edges of the surfaces of the two positioning plates away from the base plate are provided with recesses for supporting the PCBA board. The recesses on the two positioning plates are arranged opposite to each other. Each positioning plate is provided with at least one gripper on the surface of the side away from the base plate and above the recess for clamping the PCBA board. By setting two positioning plates that can move horizontally on the base plate, and providing recesses and grippers on the positioning plates, the PCBA board can be fixed on the mechanism, preventing the back and front of the PCBA from directly contacting the workbench or hand, which would cause damage to the components and circuits of the PCBA board, reducing the scrap rate and reducing enterprise costs.

[0004] Traditional PCBA board assembly is time-consuming due to the lack of a clear guiding structure. The PCBA board position needs to be adjusted repeatedly during installation. During transportation or use, external vibrations are easily transmitted to the PCBA board, causing electronic components to fall off, poor circuit contact, and affecting the lifespan and operating accuracy of the clock. Utility Model Content

[0005] The purpose of this invention is to provide a clock PCBA board with a quick-positioning pin, so as to solve the problem in the above-mentioned background art that the lack of a clear guiding structure during the assembly of traditional PCBA boards leads to long positioning time and the need to repeatedly adjust the position of the PCBA board during installation.

Detailed Implementation

[0024] 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.

[0025] Example 1: Please refer to Figures 1 to 6 The present invention provides the following technical solution:

[0026] like Figure 1 and Figure 6 As shown, a clock machine PCBA board with quick-positioning pins includes an upper shell 1, a lower shell 2, and a PCBA board body 3. The upper shell 1 and lower shell 2 are spliced ​​together to form an outer shell, and the PCBA board body 3 is installed inside the outer shell to form a clock machine; as shown Figure 4As shown, the PCBA board body 3 has insertion holes 4 at the four corners and the inner edge of each hole. A positioning pin assembly is installed inside the insertion hole 4. The positioning pin assembly includes an insertion rod 5 that is slidably connected inside the insertion hole 4. An insertion block 6 is fixedly connected to the bottom of the insertion rod 5. A pad 7 is fixedly connected to the outside of the insertion block 6. The insertion block 6 has a conical structure. The top of the lower shell 2 has a positioning sleeve 8 that corresponds to the position of the insertion hole 4. The insertion block 6 and the pad 7 are inserted into the positioning sleeve 8 to form a positioning.

[0027] like Figure 3 As shown, the plug rod 5 has a hollow structure, and its internal opening penetrates the middle of the plug block 6 and the pad 7. The pad 7 forms a shock-absorbing layer between the plug block 6 and the positioning sleeve 8. The inner side of the upper shell 1 is fixedly connected with a connecting rod 9 that corresponds one-to-one with the plug hole 4. The connecting rod 9 is inserted into the plug rod 5, and the connecting rod 9 has a hollow structure.

[0028] like Figure 4 and Figure 5 As shown, a fixing screw 10 is slidably connected inside the positioning sleeve 8. A limiting plate 11 is fixedly connected to the outer side of the middle of the fixing screw 10. The limiting plate 11 and the end of the fixing screw 10 cooperate to form a limiting structure and are slidably connected inside the positioning sleeve 8. The upper end of the fixing screw 10 passes through the pad 7 and the plug block 6 and extends into the plug rod 5. The end of the fixing screw 10 located inside the plug rod 5 is threadedly connected to the inner side of the lower end of the connecting rod 9.

[0029] like Figure 1 and Figure 2 As shown, a compression spring 13 is fixedly connected between the top of the PCBA board body 3 and each connecting rod 9, and a shock-absorbing sleeve 12 is fixedly connected between the bottom of the PCBA board body 3 and the top end face of each plug block 6. The PCBA board body 3 is installed between the compression spring 13 and the shock-absorbing sleeve 12. A mounting bracket 14 is fixedly connected to the middle of the top of the PCBA board body 3. A digital display module 15 is fixedly connected to the top of the mounting bracket 14. A flexible ribbon cable 16 is provided between the digital display module 15 and the mounting bracket 14 to achieve electrical connection. An observation window 17 corresponding to the position of the digital display module 15 is provided in the middle of the upper shell 1.

[0030] When assembling the clock PCBA board, positioning pin assemblies are pre-installed inside the insertion holes 4 at the four corners and inside the edges of the PCBA board body 3. The insertion block 6 in the positioning pin assembly has a conical structure, which can help guide the insertion into the positioning sleeve 8 corresponding to the position of the insertion hole 4 on the top of the lower shell 2. The pad 7 on the outside of the insertion block 6 enters the positioning sleeve 8 together with the insertion block 6, forming a contact buffer between the insertion block 6 and the inner wall of the positioning sleeve 8, thus initially completing the positioning of the PCBA board body 3 relative to the lower shell 2 and preventing the PCBA board body 3 from shifting during the initial stage of assembly.

[0031] Move the upper shell 1 closer to the lower shell 2, so that the connecting rods 9, which correspond one-to-one with the insertion holes 4 on the inner side of the upper shell 1, are aligned with the hollow interior of the insertion rods 5 in the positioning pin assembly and inserted. At this time, the compression springs 13 between the top of the PCBA board body 3 and each connecting rod 9 will be compressed due to the insertion pressure of the connecting rods 9. The compressed compression springs 13 will apply a downward elastic force to the PCBA board body 3, so that the shock-absorbing sleeves 12 between the bottom of the PCBA board body 3 and the top end face of each insertion block 6 are tightly fitted, forming the initial elastic support of the PCBA board body 3 in the vertical direction, and strengthening the positioning stability of the PCBA board body 3.

[0032] The fixing screw 10 inside the positioning sleeve 8 is provided with a limiting plate 11 on the outer side of the middle. The limiting plate 11 and the end of the fixing screw 10 cooperate to form a limiting structure. When the fixing screw 10 is turned, the limiting plate 11 will slide along the axial direction of the fixing screw 10 inside the positioning sleeve 8. The upper end of the fixing screw 10 will move upward along the positioning sleeve 8, pass through the pad 7 and the plug block 6 in sequence and extend to the hollow interior of the plug rod 5. Finally, it forms a threaded connection with the lower inner side of the connecting rod 9 inserted into the plug rod 5. As the fixing screw 10 is continuously tightened, the upper shell 1 and the lower shell 2 will be gradually pulled closer, making the shell splicing tighter. At the same time, the PCBA board body 3 is firmly clamped between the pressure spring 13 and the shock-absorbing sleeve 12, completing the rapid positioning and fixing of the PCBA board body 3.

[0033] During the use of the clock, the mounting bracket 14 in the middle of the top of the PCBA board body 3 provides mounting support for the digital display module 15. The flexible ribbon cable 16 between the digital display module 15 and the mounting bracket 14 realizes the electrical connection between the two, so that the PCBA board body 3 can transmit clock signals to the digital display module 15. The digital display module 15 displays the clock information. The user can check the time through the observation window 17 in the middle of the upper shell 1, which corresponds to the position of the digital display module 15. If the device is subjected to external impact, the downward pressure spring 13 at the top of the PCBA board body 3 can buffer the upward impact force through its extension and deformation. The shock-absorbing sleeve 12 at the bottom can buffer the downward force through its own elasticity. At the same time, the pad 7 can further absorb vibration between the plug block 6 and the positioning sleeve 8, protecting the stable operation of the PCBA board body 3 and the digital display module 15, and reducing the impact of vibration on the circuit and structure.
