ABSTRACT:
A shielding chassis is provided with an opening to allow passage of a shielded connector part for connection to a complementary connector part disposed to confront the opening inside the shielding chassis and mounted on a circuit board. The shielding chassis is also provided with an elastic, non-metallic conducting element mounted around the opening, the conducting element contacting a shielding element of the complementary connector part, thereby allowing parasitic currents generated by electromagnetic radiation to flow to ground without passing through the interior of the chassis.
