ABSTRACT:

FIELD OF THE INVENTION
This relates to the field of electrical connectors and more particularly to components mountable to a circuit board.
BACKGROUND OF THE INVENTION
In computers and other electronic equipment, circuit boards are utilized to which are mounted numerous electrical and electronic components. Smaller circuit cards are utilized to establish electrical connections to a larger circuit board in a manner that permits removal and disconnection, by inserting an edge of the card into a receptacle connector mounted on the board and containing an array of contacts connected to circuits of the board; contact sections of the contacts are exposed within a card-receiving cavity of the connector that engage circuit pads on the card surfaces upon card insertion. It has become useful to secure certain cards within larger modules so that components mounted on the card are protected by the module covers during handling. Such modules, such as Slot
1
processor modules, need to be accurately guided during mating with the receptacle connector so that the leading end of the enclosed card is accurately received into the card-receiving cavity of the connector, since the module covers inhibit accurate visual alignment of the card with the cavity. It is known to provide elongate retention members projecting from the board from ends of receptacle connectors to facilitate mating in similar situations.
It is desired to assure that all tolerance is eliminated between the processor module and the retention members, to eliminate looseness from the resulting mated assembly and stabilize the module against the effects of vibration and other movement.
SUMMARY OF THE INVENTION
The present invention provides resilient members adjacent the inner ends of the retention members and at opposed ends of the receptacle connector that are positioned between the retention members, to be engaged and compressed by ends of the leading end of the processor module upon full mating with the connector, as the module is latched in the fully mated position by the retention members so that the compressed resilient members continue thereafter to exert pressure to maintain the fully latched engagement of the cooperating latch members.
In embodiments where the housing of the receptacle connector includes integral mounting blocks at ends thereof, where elongate retention members are either integral with or are affixed to the mounting blocks, resilient members are retained in openings of the mounting blocks to be compressed by opposed ends of the leading end of the module cover upon full mating with the connector and latching with the retention members.
In other embodiments where the mounting blocks that are separate members affixed at ends of the receptacle connector housing and the retention members are integral with the mounting blocks, recesses are provided in the mounting blocks into which are inserted resilient members that are disposed at the connector ends to be engaged by the module cover leading end; the mounting blocks may be mountable either to the circuit board or may be locked to the connector housing.
