Circuit shell enclosure

Abstract

An enclosure for a circuit on a printed circuit board consisting of two boxes fastened to the opposite sides of the printed circuit board. The boxes each have one open side which faces the printed circuit board and seals against it by means of a gasket, creating protected areas under the boxes on both sides of the printed circuit board. The boxes are offset so that protected areas on one side of the board are directly opposite both protected and unprotected areas on the other side of the board. This allows the top sides of connectors, terminals, and feed-through fittings installed on the board to be unprotected and accessible, while their solder sides are protected as are all components of the circuit and interconnecting wiring on both sides of the board.

What is claimed is:  
     
         1 . An enclosure for a circuit on a printed circuit board, 
 comprised of two boxes,    said boxes being attached to opposite sides of said printed circuit board by fastening means,    said boxes each having one open side facing said printed circuit board,    said open side of each said box having a perimeter gasket means for sealing against said printed circuit board resulting in a protected area on both sides of said printed circuit board underneath said boxes,    such that at least one of said protected areas is opposite both protected and unprotected areas on the other side of said printed circuit board.
