Abstract
A shock absorbing insert for protecting a fragile quartz crystal includes a Teflon carrier with sloping walls which carries a number of dimple or rib shaped springs. These springs have varying spring rates increasing as they get farther from the base. The carrier is supported by a cushion spring system having a lower spring rate than that of the dimple or rib springs. This structure allows the force of mechanical shock to be distributed across the entire surface of the crystal rather than being concentrated at isolated areas of high stress.
