Abstract: Electromagnetic wave shielding material including a conductive fiber web with multiple pores and a heat dissipation unit provided in at least some pores that is so excellent in flexibility, elasticity, and creasing/recovery that it can be changed in shape freely and brought in complete contact with a surface where the material is to be disposed even if the surface has a curved shape, uneven portions, or stepped portions, thus exhibiting excellent electromagnetic wave shielding performance and prevent deterioration thereof despite various shape changes. Since heat dissipation performance is excellent, heat generated in an electromagnetic wave source can be rapidly conducted and released. Even if parts are provided in a narrow area at high density, the material can be brought in close contact with mounted parts by overcoming a tight space between the parts and a stepped portion. The invention is employed for light, thin, short, and small or flexible devices.

Abstract: A power adapter is disclosed. The power adapter includes housing parts that carries electronic components. To secure the housing parts together, one housing part includes snaps and another housing part includes protrusions and rails. During assembly, the protrusions slide under the snap, causing the snap to deflect in one direction, while the rails slide over the snap, which keeps the snap partially flat but also causes the snap to deflect in another direction. The engagement (during assembly) of the rails and the protrusions to opposing surfaces of the snap cause bi-directional deflection/bending of the snap. When each protrusion is positioned into an opening of the snap, the snap returns to a flat, non-deflected state, and the housing parts are secured together by the snap, protrusions, and rails. The rails support the snaps by limiting or preventing additional deflection of the snap, which subsequently promotes the housing remaining together.
