ABSTRACT:
A multi-pole plug connector is formed as a strip which includes a plurality of plug parts or socket parts having different respective numbers of poles; a plurality of corresponding socket parts or plug parts respectively insertable into the strip; coding elements arranged in the plug parts and the socket parts; first cooperating contours provided on the plug parts and the socket parts, and including a plurality of projections and a plurality of recesses arranged in a pattern with a predetermined pattern spacing, except in corner regions of the strip, so that the projections are normally engageable in the recesses when the plug parts are plugged into the socket parts; the corner edges of the plug parts and of the socket parts forming abutment edges of the parts, and including projection-free regions provided in the corner edges which deviate from the patterned contours so as to be purposely mismatched and nonfittingly collidable with the latter, the contours being provided with additional recesses in correspondence with the pattern spacing, but formed so that in the additional recesses either one of the further projections or a blocking element preventing the insertion of the one further projection can be inserted, and wherein the outlines of the blocking element and the one further projection are partially overlapping.
