Abstract
Abstract A backplane signal connector assembly includes a header connector adapted for mounting on a backplane and a receptacle connector adapted for mounting on a daughter printed circuit board. Each connector includes a conductive housing having a cavity for receiving at least two signal terminals and at least one ground terminal. The signal terminal has an insert molded insulating mounting body about a portion thereof to provide a module for mounting in the cavity to insulate the terminal from the conductive housing. The ground terminal is in direct conductive engagement with the housing. The terminals are stamped and formed metal components. At least one ground clip is mounted on each conductive housing in direct conductive engagement therewith and is adapted for commoning to a ground on the respective backplane and daughter printed circuit board, whereby the housing establishes a primary ground reference for the connector.
