KNIT EMI SHIELD AND METHOD OF CONSTRUCTION THEREOF

摘要

An electromagnetic interference (EMI) shield assembly (20) and method of construction is provided. The assembly (20) includes a body (22) having a wall (24) of warp knit nonmetallic yarn (26) having opposite sides (30) extending generally parallel with one another between opposite ends (32) and a plurality of weft inserted metal wires (28). The wire (28) is inserted to provide discrete bundles (44) each arranged in side-by-side relation with one another and extending beyond the opposite sides (30) of the wall (24) to provide a plurality of exposed free ends (38). The nonmetallic yarn (26) is looped about the wires (28), thereby fixing the wire (28) relative to the nonmetallic yarn (26) and to other wires (28) in an optimal EMI shielding position. Metal brackets (40) adapted for ready attachment to a source of electrical ground are attached to the exposed free ends (38). The individual bundles (40) of wires extend parallel to one another, with a gap (46) having a predetermined width (w) extending between the adjacent bundles (44).
