Abstract: A device for levering in and levering out a plug-in unit into and out of a module carrier includes a corner piece adapted for being arranged in a frontal region of the plug-in unit, and a pull lever comprising. The pull lever includes a lever positioned to be pivotable on the corner piece. The lever has a long lever arm and a short lever arm that is adapted to be supported on a lateral profile of the module carrier. The pull lever further includes a handle rotatably positioned on the long lever arm of the lever. The handle is arranged to be displaceable in a longitudinal direction between a starting position in which the handle is freely rotatable, and an engaged position in which the handle is connected force-locking with the long lever arm for pivoting the lever.

Abstract: A device for the insertion and extraction of a plug-in module into a module frame which has at least one front module bar, contains a swivel-mounted lever which is located in the front area of the plug-in module and whose short lever arm has at least one lever cam and a push-off nose and a pressure piece which is fastened to the module bar. The pressure piece absorbs the forces transferred from the lever, whereby the pressure piece has at least one recess, in which the lever cam of the lever reaches into during the insertion of the plug-in module. Furthermore the pressure piece has at least one push-off shoulder against which the push-off nose of the lever pushes off during the extraction of the plug-in module.

Abstract: A front part (3) for electro-magnetically screened-off modules (2) that are inserted into module chassis', the front part has a front panel (5) that has a longitudinal groove (7a, 7b) on each of its two narrow edges (6a, 6b). Two mounted side parts (8a, 8b) that have a L-shaped profile are arranged in such a way that the one L-leg (9a, 9b) reaches into one of the longitudinal grooves (7a, 7b) of the front panel (5), and the other L-leg (10a, 10b) can be designed as sealing body for the acceptance of a HF-seal or as contact surface (12).

Abstract: A card-holding device for locking a printed circuit card in a guide rail of a subassembly/subrack includes a retaining element that is inserted in the guide rail at the front edge of a printing circuit card when the circuit card is inserted to retain the card. The retaining element swivels outward and away against the elastic restoring force of an activating element. The activating element is releasable from the retaining element to allow withdrawal of the printed circuit card.

Abstract: A shielded module support structure for printed circuit boards 2 can be inserted on guide rail 7 and having electrical or electronic components has two parallel side walls 3 and at least four module rails 4 for bearing the guide rails 7. The module rails are anodized aluminum or an anodized aluminum alloy and have, at the front side, at least one seating surface 12 for one or more front plates 9, to improve electrical conductivity, sections of the module rails 4 are freed from the anodized layer. This can be done by removal of protrusions 18 by processes such as mechanical milling. For improved contacting, resilient contact bands 19 may be snapped onto the rails 4 into engagement with the bared seating surfaces 12. The resilient contact bands include sharp-edged breakouts 22 for conductive engagement with plates 9 for effecting a shielded enclosure about the circuit boards 2.

Abstract: A contact element having at least one leaf spring 2,3 has a U-shaped contact means 6, the two U-legs 8,9 of which taper towards their ends and can be elastically deformed with respect to each other. This contact element 1 is introduced into a guide groove 22 of a guide rail 13 of a module support structure or the like. The leaf springs 2,3 thereby contact a printed circuit board which can be inserted into the module support structure and the contact means 6, together with guide rail 13, can be clamped in a positioning hole 15 of a module rail 16 of the module support structure to thereby establish electrical contact with the module rail 16. In this manner, the interfering effect of an anodized layer on the module rail 16 is circumvented.

Abstract: A module support structure is proposed for printed circuit boards which can be inserted on guide rails. The four parallel module rails of the module support structure to which the guide rails are mounted are connected to the two parallel side walls via a special mounting technique. Specially shaped mounting bolts are used with a head bolt having a flat seating surface, a substantially cylindrical threaded shaft, as well as a transition piece disposed between the bolt head and the threaded shaft and tapering in a conical manner towards the threaded shaft. The mounting bolts are fed through cylindrical mounting holes in the module rails. During tightening, the transition piece abuts against the outer edge of the mounting holes to force the module rails against the projections disposed above or below the mounting holes. In this manner, an exact positioning of the module rails relative to the side walls is necessarily effected.

Abstract: A shielded module support structure 1 for printed circuit boards 2 which can be inserted on guide rails 7 and having electrical or electronic components is proposed comprising at least four module rails 4 for mounting the guide rails 7. The printed circuit boards 2 are assembled into plug-in modules 10, each having a front plate 9, wherein the front plates 9 are attached to a threaded-hole-strip using screws, the threaded-hole-strips seating in a groove 11, opening towards the front side of the module support structure 1, in the front module rail 4. In order to assure shielding of the module support structure 1 against interfering radio frequency fields, the front plates 9 are contacted with the module rails 4 using specially formed resilient contact bands 15 which can be snapped onto a seating surface 12 of the module rails 4.
