A cabinet for housing electronic plug-in cards has front and rear card baskets for inserting plug-in cards and first and second vertical backplanes. The front side of the first backplane faces the front of the cabinet and the front side of the second backplane faces the back of the cabinet. A distance piece connects the two backplanes and a counterbore is disposed in at least one of the rear sides of the two backplanes. The depth of the counterbore or the residual thicknesses of the backplane after drilling the counterbore is sized such that the distance between the front side of the second backplane and the front of the cabinet is a predetermined value. This ensures that the plug-in cards pushed onto the second backplane are completely received inside the rear card basket and the front plate of the plug-in cards ends flush with the rear card basket.

Cabinet for housing electronic plug-in cards and method of assembly

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.
