<p>The present invention provides devices and methods for inhibiting external interference and environmental contaminants from entering through an access portion to an internal chamber of an electronic device. An access panel (100) may be coupled to a fastening frame (105) of the electronic device. The access panel is rotatably attached to the fastening frame so that the access panel can be moved between an open and closed position over the access portion. A protruding edge can be formed around the perimeter of either the fastening frame or the access panel. The other of the access panel and the fastening frame can have a recessed portion (130) which may contain a gasket (115) or other form of a seal. The protruding edge may slide into the recessed portion such that the protruding edge (111) and the gasket are forced into contact with one another. When in contact, the protruding edge and the gasket form a substantially airtight seal, thus preventing any particulate contaminated air from entering an inner chamber of the electronic device.</p> |
