Patent

CA 2169563

A switching matrix (10) includes at least two parallel circuit boards (11, 13, 15, 17) each having plural conductive traces and multiple matrix holes (20) therethrough arranged to permit traces (21, 22) on one board to be connected to traces (23, 24) on the second board. Connection is achieved by means of a flexible non-conductive circuit jumper pin (40) having a resilient conductive sleeve (47, 49) arranged to extend between an aligned pair of holes in the two boards. The holes are conductively plated to define female contacts to radially compress the conductive sleeve. Circuit jumper pins may be moved between different matrix positions manually or by a pick and place mechanism (50) controlled from a remote location. In one embodiment, connections are made in pairs, there being four circuit boards and two conductive sleeves (47, 49) on each pin, each sleeve interconnecting a pair of traces on a respective pair of boards.

Matrice de commutation (10) entre au moins deux cartes à circuits imprimés parallèles (11, 13, 15, 17) présentant chacune plusieurs conducteurs imprimés et une matrice de trous (20) disposés pour permettre aux conducteurs (21, 22) d'une carte d'être reliés aux conducteurs (23, 24) de l'autre carte. Les connexions s'opèrent à l'aide de fiches traversantes flexibles non conductrices (40) revêtues d'une gaine conductrice élastique (47, 49) et conçues pour s'étendre entre deux trous alignés des deux cartes. Les trous, rendus conducteurs par plaquage, constituent des contacts femelle enserrant radialement les gaines. Les fiches traversantes peuvent être déplacées entre les différentes positions de la matrice manuellement ou à l'aide d'un mécanisme d'extraction/positionnement (50) télécommandé. Dans l'une des réalisations, les connexions se font par paire, quatre cartes à circuits et deux gaines conductrices (47, 49) étant placés sur chaque fiche, chacune des gaines reliant une paire de conducteurs situés sur une paire correspondante de cartes à circuits.
