How to ensure continuity in the casing overlap of the intelligent low-voltage monitoring unit?

Time：2026-02-03 Views：8次

Share：

Enclosure overlap continuity ensures low-impedance connections.

Surface contact is used: the insulating coating is removed from the contact surface.

Conductive gaskets are used: beryllium copper springs with a compression ratio of 30%-70%.

Screw fixing: spacing less than λ/20, consistent torque.

Bridging treatment: braided copper strips are used for bridging movable parts such as hinges.

Testing: overlap resistance is less than 15mΩ (DC).

By ensuring continuity, the overall enclosure shielding effectiveness is greater than 35dB.
