Electromagnetic interference shielded panel

1. A panel for use in constructing an electromagnetic interference shielded enclosure, said panel comprising:

one or more frame members, each said frame member including a first side wall extending between a first end and a second end, a second side wall extending between a first end and a second end, and an end wall connected to said second ends of said first side wall and said second side wall, said first side wall including a first surface extending from a first end to a second end, a lip extending outwardly from said second end of said first surface to an outer end, said first surface and said lip forming a first recess, a second surface extending from a first end to a second end, said first end of said second surface located at said outer end of said first lip, a third surface extending between a first end and a second end, said second end of said third surface being located adjacent said second end of said second surface, said third surface being located outwardly from said second surface such that a second recess is formed by said second and third surfaces;

a first skin member having an edge, said edge located in said second recess of said first side wall of said frame member and welded to said first side wall;

a second skin member having an edge coupled to said second side wall of said frame member, said second skin member being spaced apart from said first skin member; and

a core member located between said first and second skin members.

2. The panel of claim 1 wherein said second surface and said third surface of said first side wall of said frame member are generally parallel to one another.

3. The panel of claim 2 wherein said third surface of said first side wall is spaced outwardly from said second surface of said first side wall a distance approximately equal to the thickness of said first skin member.

4. The panel of claim 1 wherein said frame member includes a first inclined wall extending between said end wall and said second end of said first side wall, and a second inclined wall extending between said end wall and said second end of said second side wall.

5. The panel of claim 1 including a barrier member located in said first recess between said first surface of said first side wall and said first skin member.

6. The panel of claim 1 including a barrier member located between said edge of said second skin member and said second side wall of said frame member.

7. The panel of claim 1 wherein said first skin member includes an outer surface, said outer surface of said first skin member being generally coplanar with said third surface of said first wall of said frame member.
