Abstract

An RFI/EMI shield is formed of interlaced conducting and non-conducting filamentary members. The shield takes the form of a sleeve with a longitudinal seam, the sleeve being biased so that free edges defining the seam are positioned in overlapping relation. A pair of filamentary drain members are positioned adjacent to each other and covered by one of the free edges. One of the drain members is continuously interlaced with the filamentary members forming the sleeve, the other is interlaced at a plurality of attachment regions arranged in spaced relation lengthwise along the sleeve. Between the attachment regions, the drain member floats on the surface of the sleeve and is extendible away from the sleeve for attachment to an electrical ground.
