Abstract: An apparatus for the insertion and withdrawal of a plug-in module with front panel into and out of a module carrier includes a lever arm (2) pivotable about an axis (3) with a handle portion (2a) for the rotation of the lever arm as well as a bolt (5) to lock the lever arm and an operating element (5a) connected to the bolt with which the lever arm can be unlocked. The operating element (5a) is arranged spaced from the lever arm (2), and the handle portion (2a) is designed such that it contacts the front panel (10) of the plug-in module in the inwardly pivoted position.

Abstract: The figures show module carriers with one straight and one angled sheet metal cover (1, 2) which form an angle connection for a housing. Hooks (3) are bent out from the straight sheet metal lamina (1) on the inner side in order therein to receive a limb (4) of the angled sheet metal lamina (2). Elastic contact springs are formed on the hooks in order to produce a predetermined contact force on the inserted limb. The thickness of the sheet metal lamina and the dimensions of the contact springs and the hooks are matched to one another in such a manner that the hooks can be accommodated within a distance 1<16 mm from an edge (5) of the straight sheet metal lamina (1).

Abstract: The invention disclosed module carriers for electromagnetically screened, plug-in modules, which carry a front plate (2) which in turn has U-shaped limbs (3, 3', 4, 4') with lateral spring elements (5) for the screening. Through use of a suitable metallic sheet, and through a geometrical design of the limbs (3, 4) and of the spring elements (6, 17) matched thereto, it is possible to cut out and bend screening plates (10, 10'), limbs (3, 4) and spring elements (6, 17) in one piece from the sheet metal. If one can decide to adopt standardized limbs (3, 4) and spring elements (6, 17) with corresponding bending tools and if the cutting out is, for example, effected under numerical control with a laser on a sheet of stainless metal, then a high flexibility arises for different dimensions of the front plates (2) and rational manufacturing is possible even with small batch sizes.
