How should the shielding overlap of an EPS connector be designed?

When connecting shielded cables to equipment in EPS (Electric Power Supply), the shielding overlap design at the connector is crucial to ensuring shielding continuity. Design considerations:

1. Select shielded connectors: Use connectors with metal shells and elastic conductive pads (such as conductive rubber, springs, or metal braided mesh) at the interface.

2. 360-degree overlap: The cable shield should achieve a 360-degree circumferential electrical connection with the connector's metal shell through the connector's rear shell crimping ring, clamp, or welding. The "pigtail" method is strictly prohibited.

3. Connector cabinet installation: When the connector is installed on a cabinet panel, its metal shell should achieve low-impedance metal-to-metal contact with the panel. This is typically achieved by installing conductive sealing gaskets at panel openings and securing the connector shell to the panel with multiple screws.

4. Internal grounding: The connector shell should be connected to the grounding busbar inside the cabinet via a short grounding wire or directly. For unshielded connectors, the cable shield should be stripped at the entry point and grounded nearby via metal clips or crimp terminals.
