Abstract:
An insertion extraction device for attaching a printed circuit board (PCB) module to a cabinet, comprising:a mandrel having a first section on a first side thereof with a cross section characterized by a major diameter and a smaller minor diameter, and a second section on a second side thereof adapted to couple to a corresponding member on the cabinet; a retaining plate for affixing said mandrel to the PCB module; and a flexible sleeve positioned over said first section of said mandrel, said flexible sleeve having a predetermined elasticity such that when said flexible sleeve is rotated in a first direction with a torque less than a predetermined amount, said sleeve distorts to engage and turn said mandrel, and when said sleeve is rotated in said first direction with a torque greater than said predetermined amount of torque; said sleeve slips over said first section of said mandrel, thereby limiting the maximum amount of force applied for the insertion of the PCB module to the cabinet.
