A device for inserting, extracting, and locking a module into, from, and in a rack. The device includes two arms which can pivot with respect to the module and which are articulated together by a common articulation, each of them including, on the one hand, at one end, an anchor for anchoring it into the rack and, on the other hand, a non-common articulation with the module. A device immobilizes one of the arms with respect to the other when the arms are anchored in the rack. Further, associated with at least one of the arms, an elastic device works in compression between the module and the arm when its end is anchored into the rack. Such a device may find particular application in electronics modules for avionics.

Device for inserting, extracting and locking a module in a bay

A modular structure for carrying a printed circuit board, having to be connected to an electronic installation. The modular structure includes two cover plates opposite each other, contributing to defining a housing for at least one printed circuit board. The cover plates engage one another by sandwiching, via a first edge, a support for one or more connection blocks for the connection and, via a second edge, a support for a locking mechanism in order to hold the structure in a connected position. The support for the locking mechanism and for the connection blocks have ends which are separate before the assembly of the cover plate. Such a modular structure may find particular application to electronic installations of the integrated modular avionics type.

Simplified modular structure

A device for connecting an array of electronic-card-carrying modular structures to an external installation with which a flow of signals can be established, and also providing communication between the various modular structures. The device includes, near the array of modular structures, a plate provided with openings, terminal connection blocks coming from the installation, which should each be inserted into the openings and coupled directly to a connection block carried by a modular structure of the array and, fastened to the plate, a circuit for distributing signals between various modular structures, which is protected from the ambient environment. Such a device may find particular application to aircraft.
