Header connector of a future bus and related compliant pins

摘要

Header connector portion (10) of a future bus connector includes an insulative housing (12) having a bottom wall (14) defining a plurality of passageways (20) therethrough for receiving a corresponding plurality of compliant pins (22) therein and two side walls (16, 18) projecting upward from two opposite sides of the bottom wall (14), respectively. Each pin (22) includes a contact portion (24) for engaging with a complementary contact of a receptacle connector portion of the future bus, a retaining portion (26) having an embossed retention mechanism (29) formed thereon for interferentially engaging with inner walls (17) of the passageways (20) of the housing (12), and a tail portion (30) having an eye (32) of the needle engagement feature for reception in a corresponding hole defined in a PCB. The retention mechanism (29) includes two projections (27, 28), wherein one projection (27) is ramp-shaped and the other projection is either a partial sphere or a partial cylinder (28). The pins (22) are inserted into the passageways (20) so that the projections (27, 28) exert a force perpendicular to a longitudinal direction of the housing (12) on an inner wall (17) of each corresponding passageway (20).
