  • Publication number: 20100105220
    Abstract: A socket assembly for connecting an array of bulbous terminals such as balls wherein the female element is a miniature tube that has resilient prongs that grip the corresponding terminals with varying force during insertion and deletion. The tube is of resilient conductive material that has been sliced or helically partitioned into opposing prongs forming slots of a width that increases with axial distance from the end of the tube so as to allow the prongs of the connector to grip around the ball-like bulbous terminal and mechanically retain the terminal within the connector. The tubular element of the connector may be made by forming prongs in one or both ends of a tube by cuts of a width that increases with distance from the end of the tube.

  • Patent number: 7674142
    Abstract: An electrical interconnect device attaches electrical devices with a cantilever spring with out the use of solder or adhesive. The cantilever spring latches to a contact structure such that there are a plurality of contact points between the spring and the contact structure. The cantilever spring has two tines at a tip end that define an opening in the spring. The contact structure is received by the opening between the two tines so that the spring and the contact structure mate. The spring may engage the contact structure by latching to the contact structure or by a post that urges the tip end of the spring against the contact structure.

  • Patent number: 7559770
    Abstract: A socket connector for connecting a post or ball wherein the female element grips the post with resilient prongs with end tips at low insertion force but positive contact is maintained and wherein attempted withdrawal is normally inhibited by increasing force applied to the post by the female element in response to the withdrawal force. The female element comprises a tube of resilient conductive material that has been sliced or helically partitioned into opposing helical prongs so as to allow the prongs of the connector to spirally open around the post or ball-like bump and mechanically grip the post or bump as the post or bump is inserted along the longitudinal axis of the tube. The tubular element may be made by forming helical prongs in the end of a tube in helical cuts from about a mid section to one end of the tube.

  • Patent number: 7491069
    Abstract: 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.
