  • Patent number: 7229318
    Abstract: An electrical connector that includes first and second linear arrays of electrical contacts is disclosed. The first linear array is arranged in a first pattern of signal contacts and ground contacts. The second linear array is arranged in a second pattern of signal contacts and ground contacts that is different from the first pattern. The signal contacts define differential signal pairs. The signal contacts in the first linear array are elongated along a direction along which the first linear array extends.

  • Patent number: 7195497
    Abstract: A retention member aligns and stabilizes one or more insert molded lead assemblies (IMLAs) in an electrical connector. The retention member provides for alignment and stability in the x-, y-, and z-directions. Such a retention member may be in connection with a right angle header connector. The retention member provides stability by maintaining the true positioning of the terminal ends of the contacts. The retention member is expandable in length, and may be sized and shaped to fit a single header assembly or multiple position configurations.

  • Patent number: 7114964
    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.

  • Publication number: 20060068641
    Abstract: Electrical connectors having improved impedance characteristics are disclosed. Such an electrical connector may include a first electrically conductive contact, and a second electrically conductive contact disposed adjacent to the first contact along a first direction. A mating end of the second contact may be offset in a second direction relative to a mating end of the first contact. Offsetting of contacts within columns of contacts provides capability for adjusting impedance and capacitance characteristics of a connector assembly.

  • Publication number: 20050287850
    Abstract: An electrical connector according to the invention may include a first signal contact that defines a first side and a first edge, wherein the first side is greater in length than the first edge, the first edge having a first edge width, and a second signal contact that defines a second side and a second edge, wherein the second side is greater in length that the second edge, the second edge having a second edge width. The first signal contact and the second signal contact may be positioned edge-to-edge. A gap may be defined between the first edge of the first signal contact and the second edge of the second signal contact. The gap may have a gap width that is approximately equal to at least one of the first edge width and the second edge width. The connector may have a column pitch, and the gap width may be based on the column pitch. The gap width may be approximately 0.3-0.4 millimeters.

  • 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.
