Abstract: Modular automation device including a compartmented chassis which delimits an internal volume and accommodates a plurality of interface modules. Each module can be locked by a lateral pivoting lever which is journaled on one of its side walls and which cooperates with a fixed locking member on a vertical partition of its compartment. Alternatively, the lever can be journaled on a side wall of the vertical partition with the locking member located on the module.

Abstract: Automation equipment includes at least one removable interface module containing processor electronics on at least one printed circuit electrically connected to an interconnect printed circuit carried by a support via respective connectors. The printed circuit is accommodated in a casing of the module fixed to the support and electrically connected to a conductive part of the latter by a frame ground connection device which has connecting members fastened to the support and to the module, whereby mutual electrical contact is established between the module and the support. The connection members include a male member and a female member adapted to cooperate plug-and-socket fashion, and the interconnect printed circuit includes an opening through which at least one of the connecting members passes when the module is mounted on the support. This connecting member is insulated from the interconnect printed circuit where it passes through the opening.

Abstract: A portable data-processing terminal is provided comprising a central unit, a keyboard and a screen, the keyboard being disconnectable whereas the screen is connected to the central unit by an articulation device comprising at least one (cranked) bent lever, one end of which is articulated to a first face of said central unit, whereas the other end is articulated to the screen. With the (cranked) bent shape of the lever, the screen may be folded back against a second face of the central unit.

Abstract: The invention discloses a printed circuit card on which is welded at least an electronic component box as well as a thermal dissipator for dissipating the heat emitted by the component box. The component box and the thermal dissipator are respectively provided with clips and lugs which are engaged and welded in respective holes drilled in the card. A thermal drainage metallic area provided on a zone of the card located under the box forms a thermal adduction path between the box and the lugs of the thermal dissipator. This thermal drainage metallic area is further connected to a clip ensuring a privileged thermal drainage of the electronic component box.
