Abstract

An arrangement for protecting against incorrect plugging of plug-in modules on the front side and rear side of a backplane comprises pairs of guide pin elements with guide pins pointing in opposite directions that extent along a common longitudinal axis perpendicular to the backplane. The guide pin elements engage positively in corresponding guide receptacles of the plug-in modules when they are plugged on in the correct orientation relative to the guide pins. The arrangement comprises means for non-rotatably mounting the guide pin elements on the front side and rear side of the backplane in a predetermined angular position. The two guide pin elements are identical. Arranged between the guide pin elements is a central connecting member that can be inserted in a non-rotatable manner into an attachment hole of the backplane. The connecting member has two molded sections that point in opposite directions and engage positively in commensurately embodied recesses, thus establishing the angular position of the guide pins relative to the backplane.
