Abstract: A card edge connector includes a housing configured to be mounted to a host circuit board and having a card slot at the front configured to receive a card edge of a module circuit card of the pluggable module. A contact assembly is received in a cavity of the housing having cable contacts arranged in an upper contact set and lower contact set. An upper ground bus bar is electrically connected to terminating ends of the ground contacts of the upper contact set and a lower ground bus bar is electrically connected to the ground contacts of the lower contact set. A ground element is coupled to the upper ground bus bar or the lower ground bus bar and includes a board termination component configured to be terminated to the host circuit board to electrically connect the corresponding ground bus bar to the host circuit board.

Abstract: A communication system having a circuit board with an airflow opening includes a receptacle cage configured to be mounted to the circuit board adjacent a communication connector. The receptacle cage has walls including a front wall, a rear wall and side walls defining a cavity. A module channel is defined in the cavity configured to receive a pluggable module. The module channel has a module port at the front wall that receives the pluggable module. An airflow channel is defined by at least one of the walls of the receptacle cage located between the module channel and the circuit board. The airflow channel is configured to be in flow communication with the airflow opening in the circuit board for cooling the pluggable module in the module channel. The airflow channel has an airflow port at the front wall.

Abstract: A connector assembly includes a cage member having a plurality of walls defining a module cavity for a pluggable module. The walls include a top wall, a bottom wall and side walls extending between the top and bottom walls. The side walls extend to a bottom edge at the bottom wall and include mounting pins extending from the bottom edge that each have a press-fit portion configured to be press fit in a plated via of a circuit board. The bottom wall has a generally planar bottom surface facing the circuit board and a generally planar top surface facing the module cavity. The bottom wall includes a locating feature extending below the bottom surface and having a datum surface configured to engage the circuit board. The datum surface is a predetermined distance from the top surface to set a position of the top surface relative to the circuit board.

Abstract: A card edge connector assembly includes a card edge connector having a housing defining a card slot and holding contacts to electrically connect to a pluggable module and a host circuit board. The card edge connector assembly includes a plug guide having a main body including end walls and a side wall defining a cavity receiving the housing of the card edge connector and the pluggable module.

Abstract: A connector assembly includes a cage member having walls defining a module cavity receiving a pluggable module. The walls extend rearward from a front end to a rear end and surround a communication connector at or near the rear end. An EMI skirt is provided at or near the mating interface between the pluggable module and the communication connector. The EMI skirt includes plural spring beams configured to surround a mating perimeter of the pluggable module forward of a mating end of the pluggable module configured to be mated with the communication connector. The spring beams are deflectable and are elastically deformed against the mating perimeter when the pluggable module is mated with the communication connector. The spring beams have mating interfaces configured to engage and electrically connect to the pluggable module.
