The card and the spring are stably connected at the mounting hole, and two ends of the card respectively extend out of two sides of the connecting rod. After the card crosses the locating hole on the PCB circuit board, the card can make the end of the card abut against the port of the locating hole of the PCB circuit board after resetting, and finally the lower end of the connecting rod is stably connected with the PCB circuit board.
When the card is installed, the card is pushed and extruded to act force, the external force can be buffered through the spring, and the card is prevented from being in rigid contact with the PCB.
In foretell shielding magnetic shield, the card is including being the linkage segment of straight section form and the joint section of slope, and the quantity of above-mentioned joint section is two and two joint sections are located the both ends department of linkage segment respectively, and above-mentioned spring coupling is in linkage segment department.
In the shielding magnetic cover, the connecting section and the clamping section are of an integral structure, and the two clamping sections and the connecting section are symmetrically arranged on the basis.
The card is made of brass material, which enables the card to have proper elasticity. Once the two clamping sections cross the positioning hole of the PCB, the reset clamping sections can stably abut against the port of the positioning hole of the PCB.
In the shielding magnetic cover, an included angle between the connecting section and the clamping section is 100-120 degrees.
This construction enables a stable, oblique extension of the clamping section out of the side of the connecting rod.
In the shielding magnetic cover, the upper part of the connecting section is provided with a cylindrical upper positioning column, and one end of the spring is sleeved on the upper positioning column.
The end part of the spring can be stably positioned through the upper positioning column.
In the shielding magnetic cover, the lower part of the connecting section is provided with a cylindrical lower positioning column, the side part of the mounting hole of the connecting rod is provided with a concave positioning notch, the lower positioning column is matched with the positioning notch, and the lower positioning column is embedded in the positioning notch.
The lower positioning column is matched with the positioning notch to enable the card to be stably positioned in the mounting hole.
Compared with the prior art, this shielding magnetic shield is owing to can be connected the locating hole of connecting rod lower extreme and PCB circuit board stable through at elastic positioning structure, simultaneously, keeps off along stable supporting to leaning on and connecting along upper portion, and the connecting rod is worn to establish and is connected along last, finally with the stable connection of the cover body on PCB circuit board, its installation is more convenient. After the external force is applied to enable the card to be damaged and deformed, the connecting rod can be conveniently taken out from the PCB and the connecting edge, so that the connecting rod is convenient to disassemble.
Of course, the card can not be recovered after being damaged, and the lower end of the connecting rod and the PCB can be stably connected again only by replacing a new card after the card is disassembled.
In addition, because the connecting edge is tightly pressed between the blocking edge and the PCB, the connection between the cover body and the PCB is stable, the stability is high, and the practical value is high.
