Abstract

A USB device in which all of the devices ICs are located on a lower surface of a PCB (i.e., opposite to the metal contacts) to minimize the device'"'"'s thickness, and at least one of the ICs is positioned on a relatively narrow portion of the USB plug to minimize the device'"'"'s length. A card-like carrier for protecting the USB device when not in use includes a frame-like base portion having peripheral walls surrounding a relatively wide main chamber, and an end portion that is attached to the base portion and includes end walls that define a relatively narrow slot communicating with the main chamber. The USB device plug structure is inserted through the main chamber into the slot until a front edge of the handle structure abuts the end walls, and then the device is rotated downward into the main chamber.

Claims

1. A card-like carrier for a low-profile Universal-Serial-Bus (USB) device, the USB device including a relatively wide handle structure having a peripheral edge, and a relatively narrow plug structure extending from the handle structure, the plug structure including a plurality of metal contacts exposed on an upper surface thereof, wherein the card-like carrier comprises:

a base portion having peripheral walls surrounding a relatively wide main chamber;

support structures disposed on lower edges of at least some of the peripheral walls and extending into the main chamber;

one or more locking structures disposed along upper edges of at least one of the peripheral walls and extending into the main chamber; and

an end portion attached to the base portion, the end portion including end walls defining a relatively narrow slot having a first end communicating with the main chamber,

wherein the card-like carrier is constructed such that, when the plug structure of the USB device is inserted into the slot and the handle structure of the USB device is pressed into the main chamber, the handle structure of the USB device is restrained by the support structures and the locking structures such that the peripheral wall of the base portion extends along the peripheral edge of the handle structure, and the plug structure is maintained inside the slot.

2. The card-like carrier of claim 1, wherein the peripheral walls of the base portion include first and second opposing side walls extending from the first and second end walls, respectively, and a rear wall extending between the first and second side walls.

3. The card-like carrier of claim 2, wherein the support structures comprise rails extending along the lower edges of the first and second side walls between the rear wall and the first and second end walls, respectively.

4. The card-like carrier of claim 3, wherein each locking structure comprises a protrusion extending from the upper edge of one of the first and second side walls and the rear wall.

5. The card-like carrier of claim 2, wherein the end portion further comprises a cover plate extending between the end walls such that the cover plate is positioned over the metal contacts of the USB device when the USB device is mounted inside the card-like carrier.

6. The card-like carrier of claim 2, wherein a groove is defined at an intersection of the second side wall and the rear wall for receiving a key chain mounted on the USB device.

7. An assembly comprising:

a low-profile Universal-Serial-Bus (USB) device including;

a printed circuit board assembly (PCBA) including;

a printed circuit board (PCB) including a relatively wide PCB handle section and a relatively narrow PCB plug section, the PCB having opposing first and second surfaces,

a plurality of metal contacts disposed on the first surface of the PCB plug section, and

first and second integrated circuits (ICs) mounted on the second surface of the PCB, and

a housing attached to the PCBA and including a cover plate extending over both the PCB handle section and the PCB plug section,

wherein the cover plate includes a planar surface that is parallel to the PCB, and

wherein a first thickness measured between the first surface of the PCB and the planar surface adjacent to the metal contacts is substantially equal to a second thickness between the first surface of the PCB and the planar surface adjacent to the IC; and

a card-like carrier including;

a base portion having peripheral walls surrounding a relatively wide main chamber;

support structures disposed on lower edges of at least some of the peripheral walls and extending into the main chamber;

one or more locking structures disposed along upper edges of at least one of the peripheral walls and extending into the main chamber; and

an end portion attached to the base portion, the end portion including end walls defining a relatively narrow slot having a first end communicating with the main chamber,

wherein the USB device is detachably mounted onto the carrier such that the plug structure of the USB device is received inside the slot and the handle structure is restrained by the support structures and the locking structures such that the peripheral wall of the base portion extends along the peripheral edge of the handle structure.

8. The assembly of claim 7, wherein the end portion of the carrier further comprises a cover plate extending between the end walls over the metal contacts of the USB device.
