摘要： An interconnection system that includes a daughter card and backplane electrical connectors, each mounted to a printed circuit board at a connector footprint. The backplane connector has conductive elements with transition regions that allow the mating contact portions to be positioned on a uniform pitch while contact tail portions can be shaped to improve signal integrity or to provide a more compact and/or mechanically robust footprint. The conductive elements in both connectors are configured such that the contact tails of the ground conductors align from column to column, but the planar portions of the ground conductors in one column align with a pair of signal conductors in the other column, which improves mechanical and signal integrity. Mechanical integrity may be improved by forming the connector footprints with pads for the ground conductors that span multiple columns.

摘要： An interconnection system that includes a daughter card and backplane electrical connectors mounted to printed circuit boards at connector footprints. The spring rate of beam-shaped contacts in the daughter card connector increases while mating with the backplane connector so that the retention force may be greater than the insertion force. Such a change in spring rate may be achieved by positioning the beam-shaped contacts adjacent a surface of a connector housing. That surface may include a projection that aligns with the beam-shaped contact. When the connectors are unmated, the beam-shaped contact may be spaced from the projection. As the connectors begin to mate, a central portion of the beam-shaped contact may be pressed against the projection, which has the effect of shortening the beam length and increasing its stiffness.

摘要： A shielded electrical connector in which multi-beam contacts are used to improve performance of the connector. The beams are positioned to create multiple current paths through a shield member, thereby increasing the effectiveness of the shield. These contacts are used in a connector that has individual shield strips running in parallel with signal conductors. Multiple contact tails are also used to create multiple current paths. Projections from the shield strips shield adjacent signal contacts and the contact portions are positioned to increase current flow through the projections. Structures to allow beam-type contacts to be formed in a small space are also disclosed. The contact structure also reduces the impedance of the ground path.

摘要： An electrical connector has a first wafer having a first housing with a first plurality of contact beams extending from the first housing in a first plane. A second wafer has a second housing with a second plurality of contact beams extending from said second housing in a second plane substantially parallel to the first plane. A dividing panel member extends from the insulative housing between the first plurality of contact beams and the second plurality of contact beams. Each of the contact beams extending from the wafer pair is configured to mate with a corresponding backplane contact in a backplane connector. The contact beams extending from the wafer pair and the backplane contacts are configured such that each pair of corresponding contacts includes a first contact point and a second contact point. When the wafer pair is fully received by the backplane connector, contact between the contact beam and the backplane contact is maintained at both the first and second contact points. Each of the contact beams includes a pivot member configured such that the electrical connector has a low initial insertion force and develops a constant working normal force as the beams travel to and beyond the pivot member, as each mates with the backplane connector.

摘要： An interconnection system with capacitors integrated into a printed circuit board footprint of an electrical connector. One end of each capacitor shares a pad on the printed circuit board with a contact tail of a conductive element in a connector. The shared pads are not connected through vias to internal circuit structures. Rather, a via, such as which would conventionally be formed as part of the connector mounting pad, is formed as part of a separate, adjacent pad. A second end of the capacitor is attached to the adjacent pad, forming an electrical connection between the conductive element and the via through the capacitor. Incorporating capacitors into the footprint reduces the number of vias required, which improves signal integrity. The capacitors may be placed on the printed circuit board separately from the connector or may be incorporated into the connector, allowing the connector and capacitors to be placed in one operation.
