Abstract
An EMI gasket having a uniform V-shaped cross section. Parallel grooves are provided in an area on one arm of the V-shaped cross section. Each optical fiber is held by a groove of the parallel grooves. Two arms of the V-shaped crosssection are pressed toward each other by two parallel conductive plates which forms a shielding for the openings where optical fibers go through.
Claims12
An Electromagnetic Interference ("EMI") gasket for shielding electromagnetic or electrostatic interferences penetrating into a casing through openings, comprising:
- a belt comprising an inner buffer member and having a V-shaped uniform cross-section and a length, said V-shaped cross section having a first side and a second side opposite said first side;
- an outer conductive coating covering said belt;
- a plurality of parallel grooves provided in said first side of said V-shaped cross-section of said belt, said parallel grooves being positioned in a direction perpendicular to the length of said belt;
- means for holding an optical fiber in a groove of said parallel grooves;
- and
- means for holding said first side of said V-shaped cross-section toward said second side of said V-shaped cross section between two parallel conductive plates of said casing, and for compressing said belt between said two parallel conductive plates.
An Electromagnetic Interference ("EMI") gasket for shielding electromagnetic or electrostatic interferences from penetrating between a casing and a front panel, comprising:
- a belt comprising an inner buffer member and having a V-shaped uniform cross-section and a length, said V-shaped cross section having a first side and a second side opposite said first side:
- an outer conductive coating covering said belt;
- a plurality of parallel grooves provided in said first side of said V-shaped cross-section of said belt, said parallel grooves being positioned in a direction perpendicular to the length of said belt;
- means for holding an optical fiber in a groove of said parallel grooves;
- and
- means for holding said first side of said V-shaped cross-section toward said second side of said V-shaped cross section between said casing and said front panel, and for compressing said belt between said casing and said front panel.
