Abstract
An electrical interconnect assembly (1750) for electrically interconnecting terminals on a first circuit member with terminals (1770) on a second circuit member (1772). A plurality of contact members (1700) are positioned in a plurality of the through openings (1761) in a housing. The contact members include a base portion (1708), a first beam (1704) having a proximal end attached to the base portion and a distal end extending away from the base portion in a first direction, and a second beam (1706) having a proximal end attached to the base portion and a distal end extending away from the base portion generally in the first direction. The first and second beams are configured to form at least one loop. At least one tab (1716, 1718) is attached to the base portion. The tab includes at least one engagement feature (1722, 1724) mechanically coupled to a solder member (1726).
