Patent ID: 7297024

Claim:
A Universal-Serial-Bus (USB) flash-memory device comprising: a printed circuit board assembly including an elongated printed circuit board (PCB) having an insertion end and a rear end opposite to the insertion end, metal contacts disposed on a top surface of the PCB in a contact region located adjacent to the insertion end, and at least one integrated circuit electrically connected to and mounted on the PCB adjacent to the rear end; a plastic housing having a front portion and a rear portion, a flat bottom wall that extends under both the front and rear portions, a flat top wall that extends only over the rear portion, rear side wall portions extending upward from the bottom wall to the top wall in the rear portion, and front side wall portions and a front wall portion extending upward from the bottom wall in the front portion, wherein the front side wall portions and the front wall portion are shorter than the rear wall portions; and a metal wrap having a flat lower metal sheet, flat side metal sheets respectively connected at opposite sides of the lower metal sheet and extending substantially perpendicular to the lower metal sheet, and a flat upper metal sheet attached to upper ends of the side metal sheets, whereby the metal wrap defines an elongated interior region having a substantially rectangular cross-section, and front edges of the lower, side and upper metal sheets collectively define a front opening, wherein the printed circuit board assembly is substantially encapsulated inside the plastic housing such that the rear end is enclosed by the rear portion of the plastic housing, and a bottom surface of the PCB adjacent to the insertion end is covered by the front portion of the plastic housing, wherein only the contact region of the top surface of the PCB is exposed outside the plastic housing, and wherein the plastic housing is slidably inserted inside the metal wrap such that, when both the rear portion and the front portion of the plastic housing are located inside the interior region of the metal wrap, the bottom, side and top walls of the plastic housing respectively contact the lower, side and upper metal sheets of the metal wrap, and wherein the device further comprises means for securing the plastic housing to the metal wrap when the front wall of the plastic housing is aligned with the front opening of the metal wrap.
