Method and apparatus to provide electromagnetic interference shielding of optical-electrical module
View Patent ↗A pluggable optical/electrical module is disclosed. One or more features operate to decrease electromagnetic interference are implemented, which features include deforming the portions that mate together to form the housing, placing elbow deformities on extending fingers to more properly seal the housing convex shape to housing to seal gaps between multiple sections, and placing an EMI insulating material within an opening that is formed for the latch that locks the module in place in a chassis.
1. An optical/electrical module having a surface and a bail and a latch, the latch being exposed through an opening in the surface and movable in response to movement of the bail, the module further including an EMI gasket installed within said opening and underneath said latch so that an EMI seal is maintained.
2. The optical/electrical module of claim 1 wherein the surface is closed by connecting two longitudinal sections, at least one of which has a curved deformity.
3. The optical/electrical module of claim 2 further comprising a plurality of fingers extending upwardly and outwardly from said surface, said plurality of fingers each including at least two elbow shaped deformities.
4. The optical/electrical module of claim 3 wherein the fingers are present on at least three of four sides of said surface.
5. The optical/electrical module of claim 1 wherein one of the two longitudinal sections has a ledge, and a second of said sections has an indent into which said ledge fits.
6. A method of assembling an optical/electrical module having at least two elongated portions, at least one of said portions having a curved profile along a longitudinal directions thereof, the method comprising bending the curved profile into a non-curved profile to meet with the other of said elongated portions, and affixing the two elongated portions together.
7. The method of claim 6 wherein said bending further comprises the steps of placing a ledge at one end of said elongated portions under an indent at on another of said elongated portions and then forcing the two elongated portions together against the curvature of at least one of the elongated portions.
