Abstract
A rectangular connector assembly having a plurality of contacts, with each contact being enclosed in a metal shield along the contact length is disclosed. The assembly has a rectangular metallic housing that contains a plurality of contact channels through which the contacts are inserted. The contacts are insulated from the surrounding housing by a coating on the inside of the housing. The contacts are connected at one end of the housing to an intermediate printed circuit board. The other end of the housing forms the mate to a receptacle mounted on the motherboard of an electronic system. The housing assemblies are stackable because of their shape. The invention also includes a hybrid electrical-optical connector that employs VCSEL technology, so that both electrical and optical connections can be accommodated in the same connector. Further, the connector can include a connector cooling system to cool the connector.
