The assembly includes a housing in the form of a guide frame that has a hollow interior which accommodates the insertion of an electronic module therein. A heat sink is provided to dissipate heat generated during operation of a module and the heat sink has a base portion that defines a ceiling of the hollow interior. An opening in the top of the guide frame provides an attachment location for the heat sink. A separately formed base plate is inserted into the housing and it defines a bottom of the interior of the housing. ## Claims ### Claim 1 A receptacle connector assembly, comprising: a receptacle connector, the receptacle connector including a body and a plurality of conductive terminals supported thereby;

and a base plate, the base plate being configured to attach to the housing and define a bottom portion of the interior. ### Claim 2 (depends on 1) The receptacle connector assembly of claim 1, wherein the base plate includes plurality of contact members, each contact member contacts a surface of the module after insertion thereof into the interior and urging the module into contact with the heat sink member. ### Claim 3 (depends on 2) The receptacle connector assembly of claim 2, wherein the housing further includes an adapter frame and at least a pair of engagement members disposed on the opposing sidewalls of the housing, each pair of engagement members being configured to engage opposing portions of the base plate. ### Claim 4 (depends on 3) The receptacle connector assembly of claim 3, wherein each contact member is cantilevered, having respective free ends that extend above the base plate. ### Claim 5 (depends on 3) The receptacle connector assembly of claim 3, wherein the base plate further includes at least a pair of engagement tabs disposed along opposite edges thereof, each pair of engagement tabs engaging the pair of engagement members. ### Claim 6 (depends on 3) The receptacle connector assembly of claim 3, wherein the base plate further includes at least a plurality of upright tab members configured to engage sidewalls of the housing. ### Claim 7 (depends on 6) The receptacle connector assembly of claim 6, wherein: the upright tab members include: a first pair of upright tab members, the first pair being spaced apart from each other on opposite sides of the base plate in a first spacing, and a second pair of upright tab members, the second pair being spaced apart from each other on opposite sides of the base plate in a second spacing; the first and second spacings being different such the first and second pairs respectively engage opposite surfaces of the housing sidewalls; and one of the first and second pairs further include latching members that extend therefrom into the interior. ### Claim 8 (depends on 1) The receptacle connector assembly of claim 1, further including: a plurality of rib members, each rib member extending lengthwise of the housing and being spaced apart from each other in a widthwise direction to partially divide the interior into a plurality of distinct portions; and a plurality of inner wall members equal in number to the rib members, each inner wall member extending lengthwise along the rib members and vertically between the rib members and the base plate to define inner walls of the housing, which, in cooperation with the housing sidewalls, define a plurality of distinct module-receiving bays, each bay being configured to enclose a single receptacle connector therein and accommodate a single module therein. ### Claim 9 (depends on 8) The receptacle connector assembly of claim 8, wherein each inner wall member includes latching members formed therewith, which extend into the bays. ### Claim 10 (depends on 8) The receptacle connector assembly of claim 8, wherein each inner wall member includes module-orienting members, the module-orienting members extending therefrom and preventing a module from being inserted into the bay in an incorrect orientation. ### Claim 11 (depends on 1) The receptacle connector assembly of claim 1, further including an EMI gasket arranged around an entrance opening thereof. ### Claim 12 A multi-bay receptacle configured to receive a plurality of plug connectors, the receptacle comprising: a guide frame, the guide frame including: a plurality of outer walls which cooperatively define a hollow interior space of the receptacle when the receptacle is mounted to a circuit board primary top wall, a plurality of inner walls which cooperatively define, in combination with the outer walls, a plurality of individual plug-connector receiving bays, each bay being configured to receive a single plug connector therein, and an opening, the opening being disposed in a top portion and extending over the bays; a heat sink member, the heat sink member being engagable with the guide frame and extending in the opening; and a base plate, the base plate being engagable with the guide frame across the bays and forming bottoms of the bays, the base plate including a plurality of contact members formed therein, each contact member extending from the base plate in a cantilevered fashion and formed so as to provide an urging force against a plug connector inserted in any of the bays and into contact with the heat sink member. ### Claim 13 (depends on 12) The receptacle of claim 12, wherein each contact member is arranged in the base plate in discrete, spaced apart rows, with multiple rows being disposed in each of the bays. ### Claim 14 (depends on 12) The receptacle of claim 12, wherein: the base plate further includes: first tab members, each first tab member extending up from the base plate along exterior surfaces of the guide frame to engage the guide frame, with contact members being formed from the guide frame and extend from the guide frame into the interior space thereof; second tab members, each second tab member: extends up from the base plate, but spaced apart from the first tab members, is disposed proximate to an entrance opening of the receptacle, and includes latching members that extend into the interior of the guide frame; and the inner walls include latching members that extend into the guide frame interior from opposite sides of the inner walls. ### Claim 15 (depends on 12) The receptacle of claim 12, wherein the guide frame and heat sink member are die cast from a conductive material, and the base plate and inner walls are formed from sheet metal. ### Claim 16 (depends on 12) The receptacle of claim 12, wherein the guide frame further includes a plurality of elongated ribs, the ribs extending lengthwise, are spaced apart from each other in a widthwise direction and engage the inner walls to hold them in a vertical orientation within the guide frame. ### Claim 17 (depends on 12) The receptacle of claim 12, wherein the inner walls include plug connector stop members, formed therewith and extending into the bays, the stop members preventing the insertion of a plug connector incorrectly into a bay. ### Claim 18 A hybrid housing for enclosing a receptacle connector, comprising: an adapter frame, the adapter frame being formed from a solid, cast material and including a plurality of interconnected walls, cooperatively defining a hollow interior space therein configured to receive at least one receptacle connector therein, and an opening disposed in a top portion thereof; a solid heat sink member, the heat sink member being attached to the adapter frame by threaded fasteners so as define a flat heat transfer surface extending within the top portions opening at a preselected level, closing off the top portion opening, and extending between opposing walls of the adapter frame; and a base plate, the base plate being formed of sheet metal, being attached to the adapter frame so as to define a bottom surface of the adapter frame interior space, and including a plurality of contact members disposed thereon that exert a pressing force on any module inserted into the adapter frame interior space, the pressing force occurring in a direction toward the heat sink. ### Claim 19 (depends on 18) The hybrid housing of claim 18, further including at least one inner wall member disposed in the adapter frame interior space, dividing the adapter frame interior space into a plurality of module-receiving bays, each bay being configured to receive a module therein. ### Claim 20 (depends on 19) The hybrid housing of claim 19, wherein the base plate further includes a plurality of U-shaped windows defining the contact members, each contact member being cantilevered and having a curved contact surface disposed within the adapter frame interior space which extends at a level above the plane of the base plate.
