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.
Claims30
A shield for an elongate electrical conductor, said shield providing protection to said conductor against radio frequency and electromagnetic interference as well as preventing electromagnetic radiation from radiating from said conductor, said shield comprising:
- an elongated sleeve having a central space for receiving said conductor, said sleeve comprising a plurality of flexible and resilient first filamentary members interlaced together, said plurality of first filamentary members including at least some electrically conducting filamentary members;
- and
- a pair of filamentary drain members oriented substantially lengthwise along said sleeve and interlaced with said first filamentary members, said drain members being flexible, electrically conductive and in electrical contact with one another and said electrically conducting filamentary members comprising said plurality of first filamentary members, one of said drain members having a lengthwise portion extendible away from said sleeve and connectable to an electrical ground for grounding said sleeve.
A shield for an elongate electrical conductor, said shield providing protection to said conductor against radio frequency and electromagnetic interference as well as preventing electromagnetic radiation from radiating from said conductor, said shield comprising:
- a flexible elongated sleeve having a central space for receiving said conductor, said sleeve having an electrically conducting surface surrounding said central space;
- and
- a pair of filamentary drain members oriented substantially lengthwise along said sleeve, said drain members being flexible, electrically conducting and in electrical contact with one another and said electrically conducting surface, one of said drain members having a lengthwise portion extendible away from said sleeve and connectable to an electrical ground for grounding said sleeve.
