Abstract: A module carrier with a plug module (2) can be moved into and out of a rear final position (10) with an insertion and removal grip (5). A spring-actuated lock (112) at the front side (7), which secures the insertion and removal grip in the rear final position, actuates a switching element (11) for an active switching of the plug module after an effective locking position has been reached. A pressing down of the lock (12) effects a passive switching in the locked state before the insertion and removal grip (5) is unlocked after a further displacement distance of the lock and mechanically stores the unlocking in cooperation with lock (112) by means of an engagement surface (120) with the shape of a circular segment, which is held back by a guide surface (21) of the insertion and removal grip (5).

Abstract: The invention concerns a manually actuatable rotary switch with keying function for electrical engineering and electronics. The invention essentially consists of an annular magnet, a stator, engaging elements, a shaft, washers, a code disk, a scanning device and a stop. The stator is provided with a cylinder which encompasses an annular magnet. A catching element with an embedded washer, guides for engaging elements, and a code disk are associated with the upper face of the annular magnet and a washer with the lower face. A rotatably mounted and axially sliding shaft which is square with an extension is mounted in the center of the rotary switch. The washers consist of ferromagnetic or soft magnetic material. A scanning device is associated with the code disk and a stop with the washer. The cylinder is constructed as a notched rim with notch elevations and notch countersinks which engage with engaging elements. The engaging elements engage in guides which extend radially.

Abstract: The invention of module carriers made of sheet metal is shown. The module carrier has a sheet metal cover from which a cover flange extends. A side plate of the module carrier has strips which are formed out on a straight line in order to form insertion eyes which are engaged by tongues of the cover flange. Contact springs are cut free in the cover flange, and they have knobs at their ends which are arranged to protrude outwardly as contact points. Since the insertion eyes, the insertion tongues and the contact springs are arranged on the inner side of the module carrier housing so as to be protected, smooth outer surfaces are obtained and contact springs with a long permissible travel can be chosen.

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: With the invention, for a module carrier, combinations are shown of sheet metal covers with a longitudinal section which has a through-going slit for the insertion of an edge of a sheet metal cover. Since the edge is interrupted by slits or cut-outs in order to form resilient tongues and the tongues bordering on a slit have an oppositely protruding contact knob, the tongues can be provided with a bias stress when being inserted and produce a contact and holding force.

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.

Abstract: The manipulator for pushing plug connectors of a plug board out of engagement with spring strips of a component support has a lug for engaging a plug-in surface of the support in order to engage the plug connectors with the spring strips. The same manipulator is used not only for unplugging the connectors but also for establishing a connection between the plug connectors and the spring strips.
