US Patent 7252518 USB device with case having integrated plug shell

A Universal-Serial-Bus (USB) device includes a PCBA mounted inside a plastic housing, which in turn is inserted and secured inside an outer case. The case is made of metal, and includes a handle portion that is integrally connected to a plug shell. The plug shell extends over a plug portion of the PCBA, which is mounted on a corresponding substrate portion of the housing, forming a structural arrangement similar to a conventional male USB connector plug, but without having the plug shell soldered to the PCBA. The case is, for example, sheet metal that is folded into a frame-like box for receiving the housing. The handle portion engages a cover portion of the housing such that plastic tabs are received in slots formed in the casing walls.
