AI Technical Summary
Existing electronic products have difficulty simultaneously improving the strength of electromagnetic shielding structures and the ability to prevent electromagnetic interference in their structural design, making them prone to loosening or falling apart, especially in environments with vibration or shaking.
The design employs a snap-fit structure for the cover and frame. By combining the first and second snap-fit structures and utilizing the overlapping and snap-fit of the first and second spring arms, the structural strength of the electromagnetic shielding module is enhanced. Metal or alloy materials are used to improve the stability of the connection.
The structural strength of the electromagnetic shielding module has been improved, ensuring that it is not easily loosened in vibration or shaking environments. It conforms to the radiation characteristics, conduction characteristics, spectrum distribution, interference suppression and anti-interference capabilities of electromagnetic interference, and meets market standards.
