ABSTRACT:
A electromagnetically shielded and insulated housing assembly (500) is provided having a housing member (200) and a flexible member (100). The housing member has an open side (240) and enclosing sides (215). The flexible member has a layer (110,180,185) of conductive material disposed on selected areas of each opposing side (150,155). The conductive areas are electrically connected by a plurality of conductive feed-throughs (120,115). One side of the flexible member also has adhesive areas (130,125), which are separated from the conductive area. The conductive area of the flexible member is placed over the open side of the housing member and covers it, and thereby electrical contact between the housing and the peripheral edges (250) of the open side is produced. Upward folding of the flexible member bonds the adhesive areas to the opposed enclosing sides of the housing. The other side of the flexible member is connected to a main ground, thereby electromagnetically shielding the housing assembly.
