An integrated circuit test socket is provided with contact holders which support torsion spring contacts in the socket. Each contact includes a length of wire which includes a wound portion with a pair of arms extending from opposite ends of the wound portion. One of the arms terminates in a portion engaging a corresponding terminal on an integrated circuit undergoing test, and the other arm includes a portion extending through a corresponding aperture in the socket to make electrical contact with a conductor of a circuit board.

Integrated circuit test socket having torsion wire contacts

A socket for positioning and installing an integrated circuit chip having terminals on one side thereof on a conductive elastomer includes a base which positions the chip over the elastomer. A camming member is moveable relative to the base between an open position disengaged from the chip and allowing the chip to be installed in the socket to a closed position in which the actuating member engages a side of the chip and exerts a force on the chip to embed the terminals in the elastomer to thereby provide an electrical connection between the terminals and the elastomer.

A socket for positioning and installing an integrated circuit on a circuit board includes multiple contacts mounted in a base, each contacts receiving one of the leads which extend from the sides of the integrated circuit. The contacts include a pair of engagement members which are spread apart by spreader members which are forced between the engagement members by operation of an actuating member which is slidably mounted on the base, thereby permitting installation of the leads within the contacts. Upon release of the actuating member, the contact engagement members return to their initial position and engage on opposite sides of the leads, thus providing an electrical connection between the contacts and the leads. The contacts include offset lips on the upper end thereof which permits the engagement surfaces to deflect without interference with adjacent contacts. Contacts also include a contact arm which extends around the bottom wall of the socket and is clamped against the circuit board to provide electrical connections therewith.
