摘要:
A metal-tube flash-memory-drive device has an integrated slim Universal-Serial-Bus (USB) connector that fits into a standard USB socket. The slim USB connector has 4 metal contacts. The 4 metal contacts are on a circuit board that slides into a slot on a front holder to form the USB connector. Components are pre-mounted onto the circuit board. The circuit board is fitted into the slot in the front holder and then both are inserted into a front opening of a metal tube. A rear holder is inserted into a rear opening of the metal tube to seal the circuit board inside the metal tube. The 4 metal contacts may also be an integral part of a front holder-connector that fits over and edge of the circuit board. A metal or plastic shield may be added over the USB connector to cover the 4 metal contacts.

A metal-wrapped flash-memory-drive device has an integrated slim Universal-Serial-Bus (USB) connector that fits into a standard USB socket. The slim USB connector has 4 metal contacts on a circuit board that is encapsulated by a plastic case. Components are mounted onto the circuit board. A metal wrap conforms to the general shape of a plastic sub-assembly of the plastic case and a plastic cover that enclose the circuit board. The metal wrap can be bent around the plastic sub-assembly in a forming process, or can be pre-formed into a metal tube that the plastic sub-assembly is inserted into. Alignment holes in the metal wrap can fit over plastic stubs on the plastic sub-assembly, or friction can hold the metal wrap to the plastic sub-assembly. The plastic cover and case can be bonded together by molding, ultrasonically, with adhesive films, or using snaps to form the plastic sub-assembly.

A narrow flash-memory-drive card has an integrated slim Universal-Serial-Bus (USB) connector that fits into a standard USB socket. The slim USB connector has 4 metal contacts on a board that is encapsulated by a plastic case. Components are mounted onto the board on the side opposite the metal contacts. The flash-memory drive card is as narrow as the USB connector, with straight edges, since a narrow flash-memory chip is used that is packaged in a more area-efficient Ball Grid Array (BGA) package that has solder-ball connections in a two-dimensional array rather than leads around a perimeter. The BGA package and board are covered by a plastic case and a cover. The cover and case can be bonded together ultrasonically, with adhesive films, or using snaps. The cover and/or plastic case can also be formed by a molding process.
摘要:
A low-profile Universal-Serial-Bus (USB) connector includes a substantially flat base structure that is received in the lower section of a conventional female USB connector, and includes metal contacts formed on an upper surface of the base structure. Wobble or vertical play is reduced by rails extending along side edges of the base structure that are partially inserted into gaps formed between the metal case and base structure of the female USB connector. Between metal contacts on the low-profile USB connector are raised ribs (dividers) that prevent undesirable damage or contamination to the metal contacts. The connector base structure of the low-profile USB connector can be separate or can be integrated with a circuit board that holds a flash memory chip and a USB controller chip.
