A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion. Broadside coupling provides balanced pairs for very high frequency operation. The connector is assembled with multiple subassemblies, each of which has multiple pairs of signal conductors. The subassemblies are formed from an insulative portion having grooves in opposite sides into which the intermediate portions of signal conductors. Covers, holding the signal conductors in the grooves, establish the position of the signal conductors relative to reference conductors at the exterior of subassembly, so as to provide a controlled impedance. Lossy material is positioned between the pairs in a subassembly and/or contacts the reference conductors of the subassemblies, and the lossy material of the subassemblies is in turn connected with a conductive structure.

Electrical connector

A modular electrical connector with modular components suitable for assembly into a right angle connector may also be used in forming an orthogonal connector or connector in other desired configurations. The connector modules may be configured through the user of extender modules. Those connector modules may be held together as a right angle connector with a front housing portion, which, in some embodiments, may be shaped differently depending on whether the connector modules are used to form a right angle connector or an orthogonal connector. When designed to form an orthogonal connector, the extender modules may interlock into subarrays, which may be held to other connector components through the use of an extender shell. The mating contact portions on the extender modules may be such that a right angle connector, similarly made with connector modules, may directly mate with the orthogonal connector.

Extender module for modular connector

A modular electrical connector with separately shielded signal conductor pairs. The connector may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. Modules of different sizes may be assembled into wafers, which are then assembled into a connector. Wafers may include lossy material. In some embodiments, shielding members of two mating connectors may each have compliant members along their distal portions, such that, the shielding members engage at points of contact at multiple locations, some of which are adjacent the mating edge of each of the mating shielding members.

High speed, high density electrical connector with shielded signal paths preliminary class

A modular high speed, high density electrical connector configurable for use in multiple configurations, including a direct attach orthogonal configuration. The connector is assembled with modules that include shielded pairs of signal conductors with mating ends that are rotated approximately 45 degrees with respect to intermediate portions of the signal conductors. The connector may have a mating interface with receptacles in one connector and pins in the mating connector. The pins may be small diameter and may be implemented with superelastic wires so as to resist damage despite having very small effective diameter. A compact mating interface resulting from small diameter mating contact portions may enable other portions of the connector, including the shielding surrounding the signal conductors to be smaller, which may raise the resonant frequency of the connector and extend its bandwidth.

High density, high speed electrical connector

A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.

Connector for low loss interconnection system

A modular electrical connector with separately shielded signal conductor pairs. In some embodiments, the connector is may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. In some embodiments, the modules may have projecting portions, of conductive and/or dielectric material, that are shaped and positioned to reduce changes in impedance along the signal paths as a function of separation of conductive elements, when the connectors are separated by less than the functional mating range.

High speed, high density electrical connector with shielded signal paths

An electrical connector module with openings in an insulative support selectively positioned to limit dielectric loss in a signal. The connector may include a first and second conductor including first and second sides between first and second edges. An insulative support holds the first conductor adjacent the second conductor and may have at least five pedestal portions, wherein the first pedestal portion contacts the first side of the first conductor, the second pedestal portion contacts the second side of the first conductor, the third pedestal portion contacts the first side of the second conductor, the fourth pedestal portion contacts the second side of the second conductor, and at least a portion of the fifth pedestal portion is disposed between two edges of the first and second conductors. The pedestal portions may have widths less than the widths of the first and second sides of the first and second conductors.
