Abstract

In a subrack, the front plates have shank screws which extend through the front plates and are fitted into the front plates so that the front plates have virtually no ability to move, i.e., have no "play", in the radial direction, but the shank screws can still be rotated and be displaced in the axial direction. The shank screws advantageously undertake two functions simultaneously in this arrangement. When a module is inserted into the subrack, the front plate is simultaneously centered by the shank screw. It can also subsequently be fixed accurately in position on the subrack by the same shank screw. As a result, a multiplicity of modules can be inserted into the subrack next to one another without mutual hindrance.
