Description

Technical Field

[0001] This utility model belongs to the field of PCBA board technology, and in particular to a PCBA board with drop protection function. Background Technology

[0002] PCBA circuit boards occupy a very important position in various electronic devices. With the diversification, miniaturization, and lightweight requirements of various complete products, SMT manufacturing has enabled the circuit boards to be formed into various types such as multilayer boards, flexible boards, rigid-flex boards, HDI / BUM substrates, and IC packages. This can meet the needs of various products on the market. In large and ultra-large packages, it can provide a very effective chip carrier for the miniaturized chip packaging of electronic components, ensure the soldering quality of various components, and provide recognizable graphics and characters for the soldering, inspection, and repair of components on the PCB board, which can quickly improve the efficiency of assembly and maintenance.

[0003] Existing PCBA boards are widely used in various electronic products. Among them, PCBA boards used in earphone charging cases are mostly directly installed inside the earphone charging case using bolts or other mechanisms. However, since earphone charging cases are often carried in pockets, they are prone to falling. The vibration generated when the earphone charging case falls is directly transmitted to the PCBA board, which can cause the connection between the PCBA board and the earphone charging case to break or cause damage to the circuit components on the surface of the PCBA board due to vibration. Therefore, there is an urgent need for a PCBA board with drop protection to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a PCBA board with drop protection to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCBA board with anti-drop function, comprising a bottom plate and a top plate for anti-drop protection of the PCBA board in an earphone charging case, wherein a PCBA board is disposed between the bottom plate and the top plate, and a plurality of springs for shock absorption of the PCBA board in the earphone charging case are fixedly installed on the top surface of the bottom plate and the lower end of the top plate, wherein the ends of the plurality of springs fixedly connected to the bottom plate and the top plate are all fixedly connected with abutment rings, and a plurality of vertical rods are fixedly connected to the top surface of the bottom plate, wherein a plurality of through holes are vertically opened on the top surfaces of the PCBA board and the top plate, and the plurality of vertical rods slide through the plurality of through holes, wherein the vertical rods are slidably sleeved inside the springs;

[0006] The top surface of the top plate is fixedly connected with multiple mounting rings, and the inner wall of the mounting rings is provided with insertion holes. The top surface of the vertical rod is provided with an L-shaped hole, and an L-shaped insertion rod is slidably connected inside the L-shaped hole. One end of the L-shaped insertion rod extends slidably to the outside of the vertical rod body, and the L-shaped insertion rod matches the insertion hole.

[0007] Preferably, damping rods are fixedly installed between the top surface of the base plate and the ground surface of the top plate, and between the top surface and the bottom surface of the PCBA board.

[0008] Preferably, the vertical rod has strip blocks symmetrically fixedly connected to its wall, and the inner walls of the through holes in the PCBA board and the top plate are symmetrically provided with limit grooves.

[0009] Preferably, the two strip blocks fixedly connected to the outer wall of the vertical rod are slidably connected to the interior of the two limiting grooves opened on the inner wall of the through hole.

[0010] Preferably, the abutment rings fixedly connected to the ends of the multiple springs are all fixedly connected with rubber anti-slip pads on the side away from the springs.

[0011] Preferably, a rubber sleeve is fixedly fitted to one end of the L-shaped insert that slides to the outside of the vertical rod.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This drop-resistant PCBA board, when installed, first connects the through holes on the PCBA board to multiple vertical rods. At this time, the springs fixedly connected to the bottom plate will contact the bottom surface of the PCBA board. Then, connect the through holes on the top plate to the outer wall of the vertical rods. Next, press the top plate against the bottom plate to compress the springs fixedly connected to the bottom and top plates, so that the springs on the bottom and top plates are pressed against the top and bottom surfaces of the PCBA board. Then, push the L-shaped plug into the slot inside the inner wall of the mounting ring to limit the top plate. Finally, the bottom plate is installed inside the earphone charging case with bolts and other structures and electrically connected. In this way, when the earphone charging case is dropped, the springs fixedly connected to the bottom and top plates can effectively absorb shocks to the PCBA board, thereby minimizing damage to the PCBA board.

[0014] This drop-resistant PCBA board can be easily disassembled by simply moving one end of the L-shaped insert rod out of the insertion hole in the inner wall of the mounting ring. The top plate can then be removed from the insert rod, allowing for easy removal of the PCBA board. Compared to existing technologies, this device effectively protects the PCBA board from drops, facilitating its installation and removal. Attached Figure Description

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 4The main structure of a PCBA board with anti-drop function is a bottom plate 1 and a top plate 2 for anti-drop PCBA board in an earphone charging case. A PCBA board 3 is arranged between the bottom plate 1 and the top plate 2. Multiple springs 6 for shock absorption of the PCBA board in the earphone charging case are fixedly installed on the top surface of the bottom plate 1 and the lower end of the top plate 2. The springs 6 on the bottom plate 1 and the top plate 2 are respectively distributed at the four corners of the bottom plate 1 and the top plate 2, thereby improving the stability of the PCBA board 3 after installation.

[0026] The ends of the multiple springs 6 fixedly connected to the bottom plate 1 and the top plate 2 are all fixedly connected to abutment rings 5. The abutment rings 5 ​​fixedly connected to the ends of the multiple springs 6 are all fixedly connected to a rubber anti-slip pad on the side away from the springs 6. Thanks to the setting of the rubber anti-slip pad, it can prevent the abutment rings 5 ​​from scratching the PCBA board 3 when they come into contact with the PCBA board 3, and can also further cushion the PCBA board 3.

[0027] Multiple vertical rods 7 are fixedly connected to the top surface of the base plate 1. Multiple through holes 4 are vertically opened on the top surfaces of both the PCBA board 3 and the top plate 2. The multiple vertical rods 7 slide through the multiple through holes 4. Strip blocks 11 are symmetrically fixedly connected to the rod walls of the vertical rods 7. Limiting grooves are symmetrically opened on the inner walls of the through holes 4 opened in the PCBA board 3 and the top plate 2. Two strip blocks 11 fixedly connected to the outer walls of the vertical rods 7 are slidably connected to the two limiting grooves opened in the inner walls of the through holes 4. Thanks to the two strip blocks 11 fixedly connected to the outer walls of the vertical rods 7 being slidably connected to the limiting grooves opened in the inner walls of the through holes 4, the sliding direction of the PCBA board 3 and the top plate 2 can be effectively limited.

[0028] The vertical rod 7 is slidably sleeved inside the spring 6. Thanks to the slidable connection of the vertical rod 7 inside the spring 6, the spring 6 can be further limited, thereby preventing the spring 6 from undergoing lateral deformation when compressed.

[0029] Multiple mounting rings 12 are fixedly connected to the top surface of the top plate 2. Insertion holes are opened on the inner wall of the mounting rings 12. An L-shaped hole 13 is opened on the top surface of the vertical rod 7. An L-shaped insertion rod 14 is slidably connected inside the L-shaped hole 13. One end of the L-shaped insertion rod 14 slides to the outside of the rod body of the vertical rod 7, and the L-shaped insertion rod 14 matches the insertion hole.

[0030] Damping rods 8 are fixedly installed between the top surface of the base plate 1, the ground surface of the top plate 2, and the top and bottom surfaces of the PCBA board 3. Thanks to the setting of the damping rods 8, the frequency and amplitude of the vibration of the PCBA board 3 will not be amplified due to the elasticity of the spring 6.

[0031] The L-shaped insert 14 extends slidably to the side wall of one end of the vertical rod 7, where a rubber sleeve is fixedly fitted. The rubber sleeve can limit the L-shaped insert 14 when it is inserted into the insertion hole opened in the inner wall of the mounting ring 12, so that it will not easily slip out of the insertion hole.

[0032] Working principle

[0033] When using this drop-proof PCBA board, the PCBA board 3 is first inserted into multiple vertical rods 7 through the through holes 4. At this time, the abutment ring 5 fixedly connected to the top surface of the spring 6 on the base plate 1 will contact the bottom surface of the PCBA board 3. Then, the through holes 4 on the top plate 2 are fitted onto the outer wall of the vertical rods 7. The top plate 2 is then pressed against the base plate 1, thereby compressing the springs 6 fixedly connected to the base plate 1 and the top plate 2. This causes the springs 6 on the base plate 1 and the top plate 2 to be pressed against the top and bottom surfaces of the PCBA board 3. Then, the L-shaped insert 14, which is slidably installed at the upper end of the vertical rod 7, is inserted into the slot opened in the inner wall of the mounting ring 12, thereby limiting the position of the top plate 2. Then, the base plate 1 is installed inside the earphone charging case by bolts and other structures and electrically connected. In this way, when the earphone charging case is dropped, the springs 6 fixedly connected to the base plate 1 and the top plate 22 can effectively absorb shocks to the PCBA board 3, thereby minimizing the damage to the PCBA board 3.
