ABSTRACT:
The invention relates to bus type connection systems, in particular those for wiring backplanes of electronic systems, when the bus comprises connectors distributed in an irregular manner. It consists in selecting segments (D1, D2) over which the intervals (d1, d2) between the connectors are substantially constant. The structure of all the segments except one is then modified to make the effective impedance of the modified segments coincide with that of the unmodified segment. It produces a bus that is fully matched from end to end and able to operate at a very high frequency with a slight reduction of its propagation constant.
