Abstract
A Universal Serial Bus flash memory unit having an electrically conductive housing includes a spring that provides an electrically conductive, low-resistance pathway between the housing and the metal shell of the Universal Serial Bus connector so that electrostatic charge can directly discharge from the housing to the metal shell instead of discharging through electronic components within the housing.
Claims2
A Universal Serial Bus nonvolatile memory unit comprising:
- a nonvolatile memory system;
- an electrically conductive housing that encloses the nonvolatile memory system, the housing having a top lid with an inner surface and an opening at a distal end;
- and
- a Universal Serial Bus connector that is connected to the nonvolatile memory system, the Universal Serial Bus connector being movable within the opening with respect to the conductive housing between a retracted position and an extended position whereby the Universal Serial Bus connector may be inserted into a Universal Serial Bus connector port of a portable device;
- and
- a conductive spring extending upwardly from a top surface of the Universal Serial Bus connector, wherein at least a portion of the conductive spring remains in contact with the inner surface of the top lid as the Universal Serial Bus Connector moves between the retracted position and extended position and forms an electrically conductive pathway between the Universal Serial Bus connector and the conductive housing;
- wherein the spring is integral with the USB connector;
- wherein the spring is formed from a portion of a metal shell of the USB connector;
- wherein the nonvolatile memory system is formed on a printed circuit board;
- and
- wherein the connector is mounted to the printed circuit board, the printed circuit board being movable with the connector.
