Patent number: 7491069Abstract: A self-cleaning socket for contacting terminals on a microelectronic device wherein the first end of compliant tubular contactors rotate and wipe against terminals urged downwardly against the first end of the contactors. A rotational wipe of a contactor against a mating terminal breaks through any surface contamination layers on the terminal, thereby producing good electrical contact therebetween. Rotation of the first end of a contactor is caused by a downward deflection of a collar supported by two or more helical legs along a midsection of the contactor. Deflection of the collar distorts the resilient helical legs, each of which exerts a force on the collar which add up to produce a torsional force on the collar, thereby providing a rotational wipe in response to a downward urging of a terminal against the contactor. A void along the axis of the tubular contactor provides a reservoir to hold debris dislodged from the terminal and to keep the debris from interfering with operation of the contactor.Type: GrantFiled: January 7, 2008Date of Patent: February 17, 2009Assignee: Centipede Systems, Inc.Inventors: Thomas H. Di Stefano, Anthony B. Faraci, Konstantine Karavakis, Peter T. Di Stefano
