  • Publication number: 20080248693
    Abstract: A shieldless, high-speed electrical connector is disclosed. Such a connector may include a first column of electrical contacts comprising a first arrangement of differential signal pairs separated from one another by first ground contacts, and a second column of electrical contacts adjacent to the first column, the second column of electrical contacts comprising a second arrangement of differential signal pairs separated from one another by second ground contacts. The connector may be devoid of electrical shield plates between the first column of electrical contacts and the second column of electrical contacts. The connector may be capable of transferring differential signals at data transfer rates of at least ten gigabits per second through the connector while producing no more than an acceptable level of cross talk on any of the differential signal pairs.

  • Patent number: 7309239
    Abstract: A mezzanine style electrical connector is disclosed. The connector includes first and second arrays of electrical contacts extending through a connector housing. Each contact array may include single ended signal conductors or differential signal pairs or a combination of both. The contact arrays are disposed adjacent to one another such that cross-talk between adjacent signal contacts is limited, even in the absence of any electrical shielding or ground contacts between the contact arrays.

  • Patent number: 7284221
    Abstract: Methods for designing SMT connector footprints are disclosed. A circuit board may have disposed thereon an arrangement of SMT pads and corresponding vias. The arrangement of vias may differ from the arrangement of SMT pads. The arrangement of SMT pads may differ from the arrangement of contacts in a connector the footprint is designed to receive. The terminal ends of the contacts may be jogged or bent for electrical connection with the SMT pads. The SMT pads and vias may be arranged in a number of ways that increase signal contact density of the board, while limiting cross-talk and providing adequate impedance and routing space on the board. An interactive tool for designing such a footprint is disclosed.

    Abstract: Lightweight, low-cost, high-density electrical connectors are disclosed that provide impedance-controlled, high-speed, low-interference communications, even in the absence of shields between the contacts, and that provide for a variety of other benefits not found in prior art connectors. An example of such an electrical connector may include a first signal contact positioned within a first linear array of electrical contacts and a second signal contact positioned within a second linear array of electrical contacts that is adjacent to the first linear array. Either of the signal contacts may be a single-ended signal conductor, or one of a differential signal pair.

  • Patent number: 6976886
    Abstract: Lightweight, low cost, high density electrical connectors are disclosed that provide impedance controlled, high-speed, low interference communications, even in the absence of shields between the contacts, and that provide for a variety of other benefits not found in prior art connectors, such as low insertion loss. Signal contacts and ground contacts within the connectors can be scaled and positioned relative to one another such that a differential signal in a first differential signal pair produces a high field in the gap between the contacts that form the signal pair and a low field near an adjacent signal pair. Consequently, cross talk between adjacent signal contacts can be limited to acceptable levels for the particular application. In such connectors, the level of cross talk between adjacent signal contacts can be limited to the point that the need for (and cost of) shields between adjacent contacts is unnecessary, even in high speed, high signal integrity applications.

  • Patent number: 6511344
    Abstract: An electrical-connector system includes an electrical connector having a plurality of upper signal contacts arranged in at least two rows of vertically-aligned pairs. A plurality of tails electrically couple the upper signal contacts to a circuit substrate. The upper tails have a predetermined length and are spaced apart by one or more predetermined distances so that the upper tails produce a compensating cross-talk. The compensating cross-talk offsets a cross-talk produced by the upper signal contacts. The electrical-connector system also includes a plurality of lower signal contacts electrically coupled to the substrate. The lower signal contacts are substantially located between the upper signal contacts and the circuit substrate.

The receptacle could also comprise: a housing with first and second openings, contact terminals in the first opening; and contact terminals in the second opening positioned relative to the contact terminals in the first opening so as to produce an acceptable level of cross-talk therebetween, such as −40 dB. The receptacle could comprise: a housing with first and second openings; and contact terminals. Adjacent contact terminals maintain a centerline distance, and the offset between the first opening and the second opening is a function of the centerline distance of the contact terminals.
