Patent ID: 8668188

Claim:
A vibration damping device adapted to receive an electronic component and reduce vibration, the device comprising: a spring body extending along an axis and having a first axial end and a second axial end, with reference to the axis, the spring body being hollow along an entire extent of the spring body along the axis and having radially, relative to the axis, inner and outer boundaries; one or more slots formed in the spring body located intermediate the first and second axial ends of the spring body, the one or more slots extending radially, relative to the axis, through the spring body from the radially inner boundary of the spring body to the radially outer boundary of the spring body; a shaft extending substantially coaxially within the spring body, the shaft having a first axial end, a second axial end, and an internal bore extending along the axis such that the bore extends along the entire extent of the shaft along the axis and configured to extend substantially coaxially through the spring body and shaft, the shaft having a portion that is radially, relative to the axis, adjacent and opposed to the one or more slots in the spring body and spaced radially, relative to the axis, away from the spring body at the one or more slots; and a damping mechanism configured to be positioned between the spring body and the shaft, wherein the one or more slots provides axial, radial, and rotational movement of the spring body and the damping mechanism provides the damping of motion within the internal bore; wherein the damping mechanism comprises a plurality of O-rings, which are distinct from the spring body, the shaft includes at least one channel formed in an outer surface and extending annularly, relative to the axis, about the shaft, and the at least one channel is configured to hold one or more O-rings, the at least one channel and the O-rings being located adjacent to the second axial end of the spring body.
