Abstract: A heat relief socket is provided where a contact carrier substrate is provided carrying a plurality of contacts, and is supported by a frame. The frame has an open area therethrough which can receive air flow to cool the bottom of a chip carried by the socket and the contacts themselves.

Abstract: An electrical connector including a housing having a mating interface and a contact interface configured to receive an end of a flexible printed circuit (FPC) having at least one row of FPC contacts, and contacts received in the housing and extending between the mating interface and the contact interface. Each of the contacts being configured to engage a corresponding one of the FPC contacts. An insert member is received within the housing. The insert member includes individual fingers moving independently with respect to one another, and the insert member is configured to be loaded into the housing to a mated position at which each of the fingers separately engage the FPC.

Abstract: A circuit board and connector for use in an electrical connector has been provided. The circuit board comprises first and second signal contacts associated as a differential pair. A ground contact is located immediately adjacent the first signal contact and is joined directly to a ground plane provided within the circuit board. A floated contact is located immediately adjacent the second signal contact. A component interconnects the floated contact to the ground plane, forming an open circuit when a DC signal is impressed on the floated contact and a closed circuit when AC interference is impressed on the floated contact.

Abstract: An electrical contact includes a conductor spirally wrapped about itself from a longitudinal edge. The spirally wrapped conductor defines a longitudinal axis through the contact. The spirally wrapped conductor includes a center spiraled section between first and second contact ends, and the spirally wrapped conductor is compressible along the longitudinal axis.

Abstract: A high speed signal connector having a plurality of signal conductors disposed within the housing and a ground bus or plane disposed within the housing and including a plurality of coextensive layers of different conductive materials including at least a first conductive base layer having predetermined conductivity and permeability and a second conductive top layer have predetermined conductivity and permeability. A multiple layer common ground provides for improved current flow within the common ground so as to minimize cross talk between signal contacts. As a result, the present invention provides a connector for high frequency signal transmission which exhibits an attenuation characteristic which is substantially independent of frequency within a predetermined and selectable frequency range and which permits the tailoring of the attenuation and phase response of the connector as a function of frequency.
