Embodiment Construction

[0026] This description is directed to an assembly for shielding EMI from escaping (or providing an EMI plug for) a hole or opening in any enclosure where EMI or problems may arise, such as but not limited to computer System shell. Also, the assembly is functional and not just an EMI shield. Accordingly, the component may be labeled or considered to be a functional EMI protection (EMC) component.

[0027] In short, a functional EMC assembly combines a circuit board (such as a PCA, etc.) with a membrane, and the membrane is fabricated or constructed from multiple layers. These layers are chosen to provide EMI protection or control, and also to allow components to function efficiently and effectively with the circuit board-based membrane keypad once installed to plug or cover openings or holes in the housing. The film is configured to fully encapsulate the circuit board (eg, PCA), and acts as a mechanical switch for the circuit board, EMI protection, and environmental protecti...

Abstract

A functional EMI containment plug or assembly useful to block an opening or hole in an electronics cabinet or enclosure to provide EMI containment. Functionality is achieved by combining a membrane with a circuit board. The EMC assembly functions as a circuit board-based membrane keyboard, which includes tactile switches a user can press to actuate a circuit board function. The switches may be a dome switch with collapsing action (e.g., amount of travel), and the thickness of the membrane layers placed on top of the front of the circuit board is matched to the chosen dome switch to allow a proper amount of travel. The layers of the membrane act as an EMI shield. In one embodiment, the membrane includes a metal foil layer and a conductive material layer, and the combination of foil and conductive layers of the membrane provide a shield for EMI.

Description

technical field [0001] The description generally relates to enclosures, such as cabinets, racks, and the like, for mounting and enclosing servers and other computer equipment, telecommunications equipment, and electronics. More particularly, the description relates to components (or "plugs") for plugging or sealing holes or openings in enclosures to provide EMI protection (EMC) while also being functional, and which components or plugs may be considered functional sex EMC components or plugs. Background technique [0002] In many settings or environments, electronic equipment, computers and computer equipment (eg, servers, routers, etc.), and telecommunications equipment are provided in a central location in standard or conventional enclosures, such as racks and cabinets. Typically, this equipment is provided within a box or enclosure, which is then mounted within the enclosure. The use of such enclosures with configurable electronic or computer equipment can be found in d...
