Abstract
Abstract EMI-shielding strain relief boots (10, 50, 70, 80) and dust covers (90) and methods of using these boots (10, 50, 70, 80) and dust covers (90) are described. An inventive EMI-shielding strain relief boot (10) includes a flexible elongated boot body and an EMI shield (44). The boot body has a proximal end, a distal end, and an inner surface (40) defining a bore sized and arranged to contain an end portion of a transmission cable (14) and an associated cable connector (16). The EMI shield (44) extends along a substantial length of the boot body and is configured to shield a region of the bore from interfering electromagnetic radiation. The distal end of the boot body is slidable over the cable connector (16) and is conformable to and envelopable about at least a portion of a pluggable transceiver connector (18). The dust cover (90) has a flexible elongated dust cover body and an EMI shield. An inventive EMI-shielding dust cover body has a proximal end, a distal end, and an inner surface defining a bore sized and arranged to contain a flange protruding from an opening (30) in an electronic apparatus enclosure. The EMI shield extends along a substantial length of the dust cover body and is configured to shield a region of the bore from interfering electromagnetic radiation. The distal end of the dust cover body is conformable to and envelopable about the flange protruding from the opening (30) in the electronic apparatus enclosure.
