Sealing the DTU cable inlet shield requires the use of a filter connector or shielding clip. The filter connector incorporates a π-type filter to suppress noise leakage. The shielding clip presses the cable shielding layer 360 degrees to the housing, ensuring a low-impedance connection. Conductive gaskets or potting compound are used to fill gaps at the inlet to prevent electromagnetic leakage. For multiple cables, treat them separately to avoid coupling. During testing, radiated emission tests are performed, comparing the inlet before and after treatment; leakage should decrease by more than 15 dB. Sealing the inlet improves overall shielding effectiveness and ensures the system passes the radiated emission test.
