[0024] See also Figure 1-5 , an embodiment provided by the utility model:
[0025] A protective charging circuit board includes a circuit board body 1. Multiple sets of limit plates 2 are fixedly mounted on the top outer surface of the circuit board body 1, and the outer surfaces of the multiple sets of limit plates 2 are all fixedly mounted with connecting rods 3. Connecting rings 5 are movably mounted on the outer surfaces of the connecting rods 3, and guide plates 6 are connected between the connecting rings 5. A connector 7 is connected to one side of the guide plate 6, and a screw hole 711 is provided on one side of the connector 7. A connecting rod 811 is movably mounted on the inner wall of the screw hole 711, and one end of the connecting rod 811 is connected to a wire 8, and one end of the wire 8 is connected to a guide rod 9. When static electricity accumulates on the circuit board body 1, the static electricity will flow into the guide plate 6 through the connecting rod 3, and then be conducted along the guide plate 6 through the connector 7, the connecting rod 811, and the wire 8 to the guide rod 9. During the installation process, the guide rod 9 is connected to the ground wire, and the static electricity can be safely discharged to the ground, effectively avoiding potential damage to the circuit board caused by static electricity discharge.
[0026] Furthermore, the outer surface of the connecting rod 3 is provided with a thread, and the top of the connecting rod 3 is connected to a fixing ring 4. The threaded design enables the connecting ring 5 to easily slide along the connecting rod 3 and be fixed in the desired position, providing flexible assembly and disassembly capabilities while ensuring the stability and reliability of the connection.
[0027] Furthermore, the outer surface of the fixing ring 4 is serrated, and the serrated outer surface increases friction, making it easier for people to rotate the fixing ring 4 and improving people's work efficiency.
[0028] Furthermore, the top end of the connecting rod 3 is arc-shaped. The arc-shaped design not only facilitates the installation and disassembly of the connecting ring 5, but also reduces friction and resistance during the connection process, improves assembly efficiency, and increases the durability of the connecting rod 3.
[0029] Furthermore, a reinforcement plate 611 is fixedly installed between the guide plates 6. The addition of the reinforcement plate 611 enhances the connection strength between the guide plates 6, making them more stable when facing external forces and less likely to deform or be damaged, thereby ensuring the continuity and effectiveness of electrostatic diversion.
[0030] Furthermore, reinforcement blocks 712 are fixedly installed on both sides of the connector 7. The design of the reinforcement blocks 712 improves the connection strength between the connector 7 and the guide plate 6, ensuring the stability and reliability of the entire electrostatic diversion path.
[0031] Furthermore, the outer surface of the fixing ring 4 is wrapped with rubber. The rubber material has good elasticity and anti-slip properties. Wrapping the outer surface of the fixing ring 4 not only improves the comfort of holding.
[0032] Working Principle: First, snap the connecting ring 5 into place and slide it along the connecting rod 3 to the desired position. The arc-shaped top of the connecting rod 3 not only facilitates the installation of the connecting ring 5 but also increases the stability of the structure. Next, rotate the fixing ring 4 to secure the connecting ring 5. The connecting ring 5 is fixedly connected to the guide plates 6. These guide plates 6 are supported by reinforcing plates 611, forming a stable static diversion channel. The addition of reinforcing plates 611 enhances the overall strength of the guide plates 6, making them more stable in the face of external forces. The guide plates 6 are connected to the connecting rod 811 via the connector 7. The reinforcement blocks 712 on both sides of the connector 7 ensure the stability of the connection. The other end of the connecting rod 811 is connected to the wire 8, which ultimately leads to the guide rod 9. This series of connections forms an efficient static diversion path. When static electricity accumulates on the circuit board body 1, it flows into the guide plates 6 through the connecting rod 3. Then, it flows along the guide plates 6 through the connector 7, the connecting rod 811, and the wire 8, and is finally conducted to the guide rod 9. During the installation process, the guide rod 9 is connected to the ground wire, and static electricity can be safely discharged to the ground, effectively avoiding potential damage to the circuit board caused by static discharge.
