Abstract
Abstract An isotropic shock mounting to prevent damage to electronic components such as a display mounted in a hand-held signature capture terminal includes a shock gasket which extends around the edges of the display, a carrier in which the display is disposed, a formed metal bezel within which the carrier fits having a cut-out portion through which the display can be viewed, and a plurality of shock grommets positioned at the corners of the carrier to coact with the interior of the housing of the hand-held terminal. This arrangement provides for torsional and beam strength, elastic support of the display, strain relief for TAB and PCB connections, and controlled isotropic deceleration in case of an impact resulting from a fall of the hand-held terminal.
