A system is disclosed for terminating the shield a high speed cable having an outer jacket, an inner metallic shield with a portion of the outer jacket removed to expose a portion of the metallic shield, and an inner dielectric inside the metallic shield. The system includes a conductive two-part terminating member having a shield management part and a shield terminating part. The shield management part is adapted for allowing separation of the metallic shield from the inner dielectric and soldering of the shield to the shield management part, while protecting the inner dielectric from the heat of soldering. The shield terminating part is adapted for grounding the metallic shield and includes a receptacle for receiving the shield management part in conductive engagement therewith.

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.

A method is disclosed for terminating the metallic shield of a high speed cable which includes an inner dielectric inside the metallic shield, as well as a system for effecting the method. At least a portion of the outer jacket of the cable is removed to expose a portion of the metallic shield. An insulating member is positioned between the metallic shield and the inner dielectric of the cable. The cable then is positioned on a conductive terminating member having a portion in registry with the exposed portion of the metallic shield outside the insulating member. The metallic shield is soldered to the portion of the terminating member, as the insulating member protects the inner dielectric from the heat of the soldering step.

A grounding electrical connector system includes first and second mateable connector modules each having dielectric blocks mounting a plurality of terminals and a ground plate. The ground plates of the connector modules interengage with one another in a cross-shaped grounding configuration therebetween. The terminals of the connector modules are located in spaced dispositions such that a pair of mating terminals from each connector module is located in each of four quadrants defined by the cross-shaped grounding structure of the interengaging ground plate.

A pedestal connector that incorporates one or more grouped element channel link transmission lines is seen to have a dielectric body and two opposing contact ends that are intended to contact opposing contacts or traces. The dielectric body has an S-shaped configuration such that the transmission lines supported thereon make at least one change in direction, thereby permitting the use of such connector to interconnect elements lying in two different planes. The transmission lines include slots that extend within the frame and which define opposing, conductive surfaces formed on the dielectric body which are separated by an intervening air gap.

A terminal contact arrangement for a connector promotes reduction in deviation of the impedance of the connector when mated to an opposing connector and energized. The connector has an insulative housing with a plurality of terminal-receiving passages disposed in it. Conductive terminals are supported in some, but not all of the passages. The terminal contain distinct terminal sets that include a pair of differential signal terminals and at least two associated ground reference terminals. The two associated ground reference terminals are interconnected together so that electrically, they act as a single ground terminal having a width equal to the sum of the widths of the two connected ground reference terminals. The ground reference terminals of the sets are disposed in a single row of terminals, while the differential signal terminals of the same terminal set are disposed in another row of terminals spaced apart from the row of ground reference terminals. The differential signal terminals are separated from each other within their terminal row by an empty passage so that the two differential signal terminals of each terminal set are spaced farther apart from each other than they are spaced apart from their associated ground reference terminals.

A termination structure for mating a cable connector to a circuit board has a ground terminal and two signal terminals arranged in triangular pattern through the connector in order to reduce the impedance through the connector. The width of the ground terminal increases along its extent with respect to the signal terminals. This increase occurs along either a transition or contact portion of the ground terminal.

An electrical connector is provided for mating with a complementary connector. The electrical connector includes a dielectric housing having a mating portion. A cross-shaped ground plate structure is disposed in the mating portion of the housing when the electrical connector is mated with the complementary connector. The cross-shaped ground plate structure defines four plate edges and four quadrants. At least one terminal is mounted in the mating portion of the housing in at least some of the quadrants defined by the cross-shaped ground plate structure. A pair of outboard terminals are mounted in the mating portion of the housing outside a pair of the plate edges of the cross-shaped ground plate structure.
