ABSTRACT:
A housing and connection device for electronic modules consisting of two parts, one of which is fixed and the other of which is movable. The movable part is detachably connected to the fixed part via a hook and pivot, and screw. The inside of the movable part contains a series of parallel grooves suitable for holding one or more electronic modules, such as printed circuit boards. The modules make electrical contact with a first motherboard at the rear of the movable part. The first motherboard in turn makes electrical contact with a second motherboard in the movable part, located above the first motherboard. The movable part also has a removable, grilled cover with a lock and it has an expansion system to accommodate additional modules.
