Abstract:
1. An arrangement for preventing incorrect plugging of plug-in modules to the front and rear sides of a backplane, the arrangement comprising: a pair of identical guide pin elements non-rotatably mounted on the front and rear sides of the backplane in a predetermined angular position and extending along a common axis perpendicular to the backplane, the guide pin elements having guide pins pointing in opposite directions, the guide pin elements being adapted to engage corresponding guide recesses of the plug-in modules when the plug-in modules are plugged into the back plane in the correct orientation relative to the guide pins; and a central connecting member arranged between the guide pin elements that is non-rotatably insertable into an attachment hole of the backplane, the connecting member having two molded sections that point in opposite directions and engage in respective recesses of the guide pin elements, thereby establishing the angular positions of the guide pins about the common axis relative to the backplane.
