<p>A modular construction of an interface board for mounting electrical connectors comprises a plurality of interlocked modular blocks on which the connectors are mounted. Each side face of each block comprises one or more sets of locking elements which engage with a mirror-image set of locking elements on another of said blocks to prevent relative lateral motion between the blocks or structures. Motion of the blocks or structures away from each other, in a direction normal to their mated side faces, is prevented by providing a tapered mortise in each of said side faces, the adjacent mortises of adjacent interlocked blocks or structures being in mutually confronting, aligned relationship to each other so that the tenons of a double dovetail wedge can be inserted into both mortises simultaneously to hold them in fixed position. A resilient hooked projection integral with the wedge enrages a detent in one of the block side faces when the wedge is fully inserted, to prevent its later loosening and accidental removal.</p> |
