ABSTRACT:
A box (100) includes one or more housings (130) each of which is capable of receiving a memory module (MM). The memory modules have longitudinally extending side grooves and the housings are provided with corresponding module-guiding tongues (111) and 112). The back of each module includes orifices for engaging centering pegs (PC11 and PC12) to ensure that a male connector portion (C1) on the memory module is properly engaged with a female connector portion (C2) which is cushion-mounted at the back of each housing. A switch (IC10) detects when a module is fully inserted and the connectors are properly engaged. Complete insertion of a memory module is ensured by means of a toothed sector (121) engaging a rack segment (SC21) located at the front of one of the grooves. The toothed sector (121) is actuated by a lever (125) which closes across the front of the housing (130) and is locked in place by means of a screw (128) having a knurled knob (127).
