Abstract
An edge card interconnection system provides enhanced electrical interconnection between a module and a circuit board. Electrical contact length is minimized and deflection of the contacts is controlled as the system is configured to eliminate the need for the contacts to absorb module thickness tolerances. A latching mechanism is easily manipulated and provides significant protection to modules being installed/extracted. A hold-down mechanism facilitates enhanced engagement of the connector with the printed circuit board. An insulative connector portion includes a back-up spring that pushes an inserted module against a set of contacts. Deflection of the contacts is controlled by a wall of the connector portion that prohibits the module from deflecting the contacts beyond a preset amount. The back-up spring absorbs any tolerance(s) in board thickness. A module latch and protection mechanism includes latch arms for engagement with a connector body, the latch arms have tabs disposed thereon upon which manual forces are exerted to release the latch arms from the associated connector body latch mating portion. A connector hold-down mechanism is provided which snaps onto ends of the ins…
