Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
In a modular structure for electronic apparatus implemented with circuit boards, a support frame, a plurality of modular printed circuit boards each of which has an upper edge, a lower edge and an edge connector, a plurality of board connectors mounted side by side on said frame and in mating engagement with said edge connectors, guide means on said frame for supporting said printed circuit boards, said guide means being arranged in parallel order and mating the upper edge and the lower edge of said circuit boards to guide said circuit boards during insertion into said frame and said edge connectors into corresponding board connectors, at least one of said printed circuit boards being provided with a stiffening frame extending outwardly from a surface of the board and mounted on a portion of said surface spaced from said upper and lower edge to provide non-interferring engagement of said board with said guide means, at least one fixed portion of a cable connector rigidly affixed to said stiffening frame, flexible connection means disposed between said board and said connector fixed portion, and attaching means for attaching said stiffening frame to said support frame.
