A broadside coupled connector assembly has two sets of conductors, each separate planes. By providing the same path lengths, there is no skew between the conductors of the differential pair and the impedance of those conductors is identical. The conductor sets are formed by embedding the first set of conductors in an insulated housing having a top surface with channels. The second set of conductors is placed within the channels so that no air gaps form between the two sets of conductors. A second insulated housing is filled over the second set of conductors and into the channels to form a completed wafer. The ends of the conductors are received in a blade housing. Differential and ground pairs of blades have one end that extends through the bottom of the housing having a small footprint. An opposite end of the pairs of blades diverge to connect with the wafers. The ends of the first and second sets of conductors and the blades are jogged in both an x- and y-coordinate to reduce crosstalk and improve electrical performance.

High speed, high density electrical connector

A short, high density interposer. The interposer has multiple contacts, with upwards and downwards-facing contact surfaces. Each of the contacts may be formed as a beam stamped from a sheet of metal. Two sheets of metal may be used in forming the interposer. A first sheet may be stamped with upwards facing contacts. A second sheet may be stamped with downwards facing contacts. Bases of the beams on the first sheet may be fused with bases of the beams on the second sheet, creating a conducting path through the interposer, with compliant contacts at each end. The joined contacts may be separated from the sheets from which they are stamped and held together with an insulative base of the interposer. Beams shaped to form contacts in the interposer may be closely spaced when stamped in a sheet of metal and may have a low height.

Small form factor interposer

An interposer assembly including a plate and a plurality of conductive contacts extending through plate passages for forming electrical connections with pads on overlying and underlying substrates.

Interposer assembly and method

A cable termination assembly configured for mounting to an interior portion of a printed circuit board. The cable termination assembly has a frame shaped to receive a paddle card to which a plurality of cables are terminated. A lid, when closed, may force the paddle card into contact with an interposer, which in turn may be pressed into a printed circuit board on which the cable termination assembly is mounted. Electrical signals may pass between the cables and traces in the printed circuit board via the paddle card and interposer. The termination assembly may be mounted near a processor or other high speed component on the printed circuit board, enabling high speed signals to be coupled with low loss between a periphery of the printed circuit board, or even a location off the printed circuit board, and the high speed component.

Method of forming an electrical connector

An electrical interconnection system with high speed, high density electrical connectors. One of the connectors includes a mating contact portion that has multiple contact surface. The mating contact portion has multiple segments, each with a contact surface, such that multiple points of contact to a complementary mating contact portion in a mating connector are provided for mechanical robustness. Such a mating contact may have parallel elongated members on which the mating surface are positioned, providing for the possibility of more than two contact surface per mating contact portion. The mating contact surfaces may be positioned on the elongated members such that the points of contact are at different distances from the distal end of the mating contact portion.

Mating contacts for high speed electrical connectors

An electrical interconnection system with high speed, high density electrical connectors. One of the connectors includes a mating contact portion that generates contact force as it is compressed against a wall of the connector housing. The mating contact portion has multiple segments, each with a contact region extending from the wall, such that multiple points of contact to a complementary mating contact portion in a mating connector are provided for mechanical robustness. Additionally, each signal path through the mating interface portions of the connectors can be narrow and has a relatively uniform cross section to provide a uniform impedance. Additional size reduction may be achieved by mounting a ground contact on an exterior surface of a connector housing in alternating rows. Additionally, embodiments in which a wavy contact is used in a cantilevered configuration are also described.

Compressive contact for high speed electrical connector

An electrical connector with a reference contact for improved shielding. The contact provides multiple points of contact between members in the ground structure of two mating connectors. The points of contact are arranged to provide desirable current flow in the signal paths and ground structures of the connectors. The contact is stamped from a shield plate and has multiple elongated members that provide spring force for adequate electrical connection. The elongated members are curved to position the points of contact with the desired orientation. Such a contact structure may be used alone or in combination with other compliant structures providing further points of contact.
