ABSTRACT:
A weathertight and EMI shielded cabinet (10) for housing electronic equipment is disclosed. The cabinet (10) is structurally supported and framed by a tubular frame (30) which defines a generally rectangular structure having upper horizontal frame members (34, 36), lower horizontal frame members (38, 40), and vertical corner posts (42). The tubular frame (30) may include internal cross members (60, 62) to further reinforce the structure. Door openings are further defined by vertical door frame members (56). A plurality of outer skins (80, 84, 110, 111, 112, 90, 102) are welded to the tubular frame (30) and substantially enclosing it and hiding it from view. The outer skins also define the door frames (90, 92, 94, 102, 104, 106) welded to the vertical door frame members (36) and upper and lower horizontal frame members (34, 36, 38, 40), forming a generally vertical door-frame mating plane. The doors (16, 18) are hung in the door openings and operable to substantially close the door opening and meet the door-frame mating plane. Flat strips of environmental and EMI shielding gaskets (100, 132, 138) are used between the door (16, 18) and the door frame skins (90, 92, 94, 102, 104, 106) where they meet in the door-frame mating plane.
