ABSTRACT:
A mechanism is provided as part of a test clip for locking the clip to the body of an integrated circuit device, at the corner regions of the IC body. The mechanism includes locking fingers (62, FIG. 4 ) that are formed of metal spring wire, with each finger having an upper part (84) fixed to a base (22) that closely engages an upper portion of the IC body, a middle part (84) that extends at a downward-axially outward incline, and a lower finger end (66) that engages a lower portion of the IC body. When a shaft (72) is pushed down against the biasing of a spring (74), the shaft moves down an actuator (64) that has prongs (80) which press against the middle parts of the locking fingers to deflect them radially inwardly, so the finger lower ends slide radially inwardly along grooves (112) formed in the base, to engage the lower portion of the IC body.
