Abstract
A mounting frame for supporting several printed circuit boards in abutting relationship includes a pair of side frame members. At least some of the printed circuit boards have slots along or near the side edges, through which screws extend into the side frame members. The screw heads extend over and retain the printed circuit boards in position. When the screws are loosened for some of the boards, those boards can be displaced from each other but not removed from the frame. Additional loosening of one set of screws allows the removal of that one board, even if that board is not the last board in the run of boards. Cylindrical bores are provided in at least one of the side frame members to afford pivotal mounting of the frame-and-card set in an enclosure. When the frame-and-card assembly is pivoted outwardly, an additional set of cards can be mounted on the back of the frame. Cylindrical stand-offs are provided in the back of the enclosure, so that upon rotation of the frame assembly, electrical connection is made through banana plugs which extend between the frame side member and the stand-off.
