  • Patent number: 5228861
    Abstract: An electrical connector (10) for interconnecting a component (50) and a circuit (58) having pads (54, 60) on closely spaced centers for high density packaging includes a thin, dielectric member (12) carrying contacts (20) on centers compatible with the centers of the component and circuit pads; the contacts having spring arms (28, 32, 36, 40) extending from a central mounting portion (22) in a star-like configuration to provide an outward wiping engagement with component and contact pads as the contact is compressed by displacement of the component toward the circuit. The contact arms are of a geometry and have characteristics to provide a balanced force precluding rotary or twisting loads on the dielectric member and are tapered to further provide a desired deflection and sufficient normal force to define a stable, low-resistance electrical interface.
