Pluggable module and receptacle

A pluggable module system comprising:

• a receptacle mounted to a host circuit board within a chassis of a host system, said receptacle comprising a housing having a front, a back wall, a top wall, a bottom wall, and side walls and defining a cavity for receiving a module, said bottom wall having a bottom opening to receive a receptacle connector, said front having a front opening to receive said module, the walls comprising a conductive material and being electrically connected to said host circuit board;
• a receptacle connector electrically connecting to said host circuit board and protruding into said cavity through said bottom opening, said receptacle connector being adapted for electrically connecting said module to said host circuit board;
• and
• a module comprising a module housing having a front end and a back end and being adapted for insertion into said receptacle and grounding contacts configured for electrical connection to said housing of said receptacle.

A module for electrically connecting to a mating connector mounted to a host circuit board the module comprising:

• a housing having a front and back orientation and a top and bottom orientation, said housing having a top wall, a bottom wall, a back wall and side walls, each of said top wall, said bottom wall, and said side walls being planar;
• a planar module circuit board comprising at least an edge portion comprising pads suitable for forming an electrical connection with contacts of the mating connector, said module circuit board being enclosed by the planes of said top wall, said bottom wall, and said side walls, and wherein said back wall only partially covers the back of said module such that said edge portion is accessible from the back of the module along the plane of said module circuit board;
• and
• a connector interface at the front of said housing, said connector interface being adapted for receiving a connector of an electrical or optical conductor.
