Connecting apparatus for electrically connecting memory modules to a printed circuit board

Connecting apparatus for electrically connecting memory modules having electrical contacts substantially along one of the module's edges to a PCB of a digital electronic circuit comprising:

• at least two channel mounts, each having a channel therein for edge-wise receiving said memory modules, each said channel containing spring contacts for electrically coupling the edge contacts of said memory modules when the module is inserted and rotated in said channel and for producing a moment thereon, and each channel capable of accepting the edge of one memory module;
• lead means for electrically coupling the spring contacts in the channels to electrical lead lines on the PCB;
• one end retention post at each end of each channel, each said end retention post including a latch for holding a memory module in a fixed position while inserted into a channel by opposing the moment produced by said spring contacts on the memory module edge contacts, said end retention posts being flexible in the longitudinal direction of the channel to allow separation thereof for insertion of said memory module therebetween;
• and
• at least two side retention posts, separate from said end retention posts, for preventing a connected memory module from rotating beyond a predetermined angular position, each said side retention post having a securing peg thereon above the plane of the channel mount for engaging a securing hole of said module and for extending through the full thickness of said module to provide positive locking of said memory module in said channel.

• at least two side retention posts on each channel mount for lateral positioning and restraint of a memory module, each said side retention post having securing pegs that protrude through securing peg holes in the memory module for vertical positioning and restraint of the memory module;
• separate control lead lines coupled to spring contacts on separate channel mounts, each channel to activate one module at a time for data transfer;
• and
• common data and address lead lines coupled to spring contacts on both channel mounts, each said data and address line coupled to a corresponding electrical contact on each channel for transferring data and address signals.
