  • Publication number: 20090219702
    Abstract: An electronic plug-in module to be accommodated in a mounting rack with a module rail in the front region comprises a circuit board, a circuit board holder and an adapter. The adapter features a receptacle for a mounting element in order to mount the adapter on the module rail. The circuit board holder is fixed on the circuit board in the front corner region of the circuit board. It features a coupling structure that is coupled to a corresponding coupling element of the adapter in order to produce a coupling between the circuit board holder and the adapter. In an end position of the plug-in module in the mounting rack, the adapter and the circuit board holder cooperate in such a way that the plug-in module is held in its position in the mounting rack.

  • Publication number: 20080212265
    Abstract: The present invention pertains to a switchgear cabinet for accommodating electronic plug-in modules with an interior in which the heat-generating plug-in modules can be inserted one on top of another, a roof area arranged above the interior and a base arranged underneath the interior and that forms a base area. The switchgear cabinet furthermore comprises an air channel that is arranged to the side of the interior and connects the roof area to the base area. A closed cooling circuit within the switchgear cabinet serves for carrying off the heat generated by the plug-in modules. A fan arranged in the roof area takes in air from the interior and blows this air into the air channel. The heated air from the air channel flows around a heat exchanger arranged in the base in such a way that the air is cooled and the thereby produced cooling air is admitted into the interior from below and flows through this interior vertically upwards.

  • Patent number: 6915562
    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.

  • Patent number: 6447082
    Abstract: The invention relates to a subrack (1) for industrial electronics. The front and/or rear edge of a cover sheet (4) and that of a base sheet (6) are formed by edge-folding for fixing a specially configured angular strip (12). This enables known module rails to be integrated with the cover or the base and means that said module rails can be produced from sheet steel, which significantly reduces the production costs.

  • Patent number: 6134119
    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.

  • Patent number: 6083037
    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.
