Abstract
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.

An interconnection system comprising a first component comprising a first plurality of conductive elements held by a first dielectric housing and a second component comprising a second plurality of conductive elements held by a second dielectric housing, wherein:
- the first plurality of conductive elements are configured to provide first signal paths within the first component, the first signal paths having a first impedance;
- the second plurality of conductive elements are configured to provide second signal paths within the second component, the second signal paths having the first impedance;
- and
- the first plurality of conductive elements, the second plurality of conductive elements, the first dielectric housing, and the second dielectric housing are configured to provide a mating region having a length that varies in relation to a separation between the first component and the second component, and
- when the first plurality of conductive elements are mated with the second plurality of conductive elements, the impedance varies across the mating region to an inflection point with a second characteristic impedance such that a change in impedance from the first impedance at the first signal paths within the first component to the second impedance at the inflection point and from the second impedance at the inflection point to the first impedance at the second signal paths within the second component is distributed across the mating region.
An interconnection system, comprising:
- a first component comprising a first plurality of conductive elements held by a first dielectric housing;
- a second component comprising a second plurality of conductive elements held by a second dielectric housing, wherein:
- the first plurality of conductive elements are configured to mate with the second plurality of conductive elements in a mating region having a length that varies in relation to a separation between the first component and the second component to provide at least one signal path between the first plurality of conductive elements and the second plurality of conductive elements, wherein the at least one signal path has an impedance at a frequency of interest, and wherein:
- the impedance varies by less than 4 Ohm when the length of the mating region varies while the first and second plurality of conductive elements are mated.
