Abstract

A centering strip for plugging onto a backplane printed circuit board provided with contact blades accepts plugs in a housing opening and accepts contact blades through openings in a floor of the centering strip. In order to guarantee that the individual cable plugs are correctly plugged into the proper location on the centering strip and that the centering strip is not damaged when the plug is inserted into the housing opening, the centering strip is divided into a plurality of segments by transversely oriented partitions. The partitions have two sides on an upper half portion which forms a mechanical coding devices for the plugs to be accepted. The lower half of the partitions are provided with cavities for acceptance of contact blades. The depth of the cavities is dimensioned such that the centering strip is supported on the contact blades by a solid middle part located between the upper and lower half portions of the partitions.
