ABSTRACT:
A low insertion force, high contact force, electrical contact system, for use in a disk drive unit or printed circuit board, comprised of a socket contact and an insertion pin. The socket contact is provided with a mating region and a retention region. The mating region is formed of two independent opposed cantilevered contact beams embossed with contact dimples on their inwardly facing surfaces for engaging electrical pins. The cantilevered contact beams extend away from the retention region toward a pin-receiving end, and are angled inwardly toward each other to form a "flask" shape. Constant insertion forces are maintained on an insertion pin by the frictional forces produced by the embossed contact dimples. With a pin fully inserted into the socket contact, efficient mechanical and electrical contact is achieved by virtue of the compression and torsional forces produced by the independent cantilevered contact beams.
