An electrical connector includes a wafer formed with a ground shield made from a non-conductive material made conductive with conductive particles disposed therein, thereby eliminating the necessity of the metal ground shield plate found in prior art connectors while maintaining sufficient performance characteristics and minimizing electrical noise generated in the wafer. The wafer housing is formed with a first, insulative housing at least partially surrounding a pair of signal strips and a second, conductive housing at least partially surrounding the first, insulative housing and the signal strips. The housings provide the wafer with sufficient structural integrity, obviating the need for additional support structures or components for a wafer. Ground strips may be employed in the wafer and may be formed in the same plane as the signal strips. The second, conductive housing may be connected (e.g., molded) to the ground strips and spaced appropriately from the signal strips. The wafer may also include air gaps between the signal strips of one wafer and the conductive housing of an adjacent wafer further reducing electrical noise or other losses (e.g., cross-talk) without sacrificing significant signal strength.

A midplane has a first side to which contact ends of a first differential connector are connected and a second side opposite the first side to which contact ends of a second differential connector are connected. The midplane includes a plurality of vias extending from the first side to the second side, with the vias providing first signal launches on the first side and second signal launches on the second side. The first signal launches are provided in a plurality of rows, with each row having first signal launches along a first line and first signal launches along a second line substantially parallel to the first line. The second signal launches are provided in a plurality of columns, with each column having second signal launches along a third line and second signal launches along a fourth line substantially parallel to the third line.

A connector for transmitting signals using electrostatic coupling, comprises an inner first conductor portion and an outer first conductor portion respectively connected to two signal lines, an inner electrode portion having a facing area larger than the cross-sectional area of the inner first conductor portion in the direction perpendicular to the direction of the common axis, an outer electrode portion outside it, an inner second conductor portion for electrically connecting between the inner first conductor portion and the inner electrode portion, and an outer second conductor portion outside it, wherein the ratio of outer diameter of the inner second conductor portion to inner diameter of the outer second conductor portion is set to provide substantially fixed characteristic impedance at every position along the direction of the common axis.

An electrical connector according to the invention includes a linear contact array of electrically conductive contacts and a lead frame into which the contacts at least partially extend. The contacts may be selectively designated as either ground or signal contacts such that, in a first designation, the contacts form at least one differential signal pair comprising a pair of signal contacts, and, in a second designation, the contacts form at least one single-ended signal conductor.

An electrical connector with electrically lossy materials bridging ground members. The lossy conductive members may be formed by filling a settable binder with conductive particles, allowing the partially conductive members to be formed through an insert molding process. Connectors assembled from wafers that contain signal conductors held within an insulative housing may incorporate lossy conductive members by having filled thermal plastic molded onto the insulatative housing. The lossy conductive members may be used in conjunction with magnetically lossy materials. The lossy conductive members reduce ground system do resonance within the connector, thereby increasing the high frequency performance of the connector.

An electrical connector includes a dielectric housing that holds a plurality of electrical wafers. Each of the wafers includes a first side, a second side opposite the first side, and a forward mating edge. A plurality of contact pads on the first side are recessed from the forward mating edge, and a perimeter conductive trace is closer than the contact pads to the forward mating edge.

An electrical connector (100) includes a unitary insulative housing (1) including a base (10) defining a number of parallel slots (13) and a first shroud (11) extending forwardly from the base, a number of parallelly arranged circuit board modules (3) and a metal stiffener (2) attached to the housing. The circuit board modules are retained by and between the metal stiffener and the housing. Each circuit board module includes a dielectric spacer (30), a circuit board (36) attached to the dielectric spacer and received in a corresponding slot of the housing, and a row of press-fit contacts (38) mechanically and electrically connecting with the circuit board. The metal stiffener includes a second shroud (201) vertically spaced from the first shroud. The circuit boards have mating portions (362) disposed between the first and the second shrouds.
