Abstract
Abstract An assembly of matable connectors includes first and second connectors (10,100) each including housings (16,116) having a respective plurality of signal contacts (24,124) each having a front contact section (46,146) extending transversely of the connector's mating face (12,112) to a free end (52,152) from a bend section (44,144) adjoining the contact's body section (40,140). The front contact sections (46,146) of each associated pair extend forwardly of the respective mating faces to engage each other proximate their free ends and deflect each other rearwardly about bend sections (44,144), which results in low mating force and high cycle life. The connector housings (16,116) can include a durable latching system comprising a latch arm (18) of one connector (10) having a spaced apart pair of beams (208) having pairs of latches (210) and each being received into latching slots (252) of the other connector (100) near both lateral ends of the connectors, latching proximate both lateral ends.
