Abstract

A Universal-Serial-Bus (USB) device includes a PCBA mounted inside a plastic housing molded from a hard plastic (e.g., PC), and includes a handle portion mounted over a body section of the PCBA, and a plug support portion that is snap-coupled onto the housing and disposed under a plug section of the PCBA. The plug shell portion of the housing is integrally connected to (i.e., molded at the same time as or connected by way of molding to) the handle portion, and combines with the plug support structure extending under the plug section of the PCBA to form a structural arrangement similar to a conventional male USB connector plug that allows access to metal contacts formed on the PCBA, but without having the plug shell soldered to the PCBA.

Claims

1. A Universal-Serial-Bus (USB) device comprising:

a printed circuit board assembly (PCBA) including;

a printed circuit board (PCB) having opposing upper and lower surfaces and including a PCB body section and a PCB plug section,

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

at least one integrated circuit (IC) mounted on the PCB body section, the IC including means for processing USB signals transmitted to the plurality of metal contacts; and

a plastic handle portion including a front wall defining a front handle opening, a rear wall, and first and second side handle walls respectively extending between the front and rear walls and defining a hollow handle region;

a plug shell structure attached to and extending from the front wall of the plastic handle portion, the plug shell structure including a lower shell wall, first and second shell side walls extending upward from the lower shell wall, and an upper shell wall integrally connected to upper ends of the first and second shell side walls, wherein the plug shell defines a hollow interior region that communicates with the hollow handle region via the front handle opening, and wherein front edges of the lower shell wall, the first and second shell side walls, and the upper shell wall define a front opening; and

a plug support structure having a first end portion that is coupled to the plastic handle portion, and a second end portion that extends through the front handle opening and is received in the plug shell structure,

wherein the PCBA is mounted into the handle portion such that the PCB body section is disposed between the front and rear walls, and the PCB plug portion extends through the front handle opening and is supported on the plug support structure such that the upper shell wall is positioned over and spaced from the upper surface of the PCB plug section by a predetermined gap.

2. The USB device according to claim 1, wherein the plastic handle portion and the plug shell structure comprise an integrally molded plastic housing.

3. The USB device according to claim 2,

wherein the plug shell structure defines a pair of guide grooves respectively defined by the shell side walls, and

wherein opposing side walls extending along the second end portion of the plug support structure define rails that are slidably received in the pair of guide grooves.

4. The USB device according to claim 1,

wherein the plug support structure comprises:

a lower support wall; and

a plurality of support ribs disposed on an upper surface of the lower support wall, and

wherein the PCBA is mounted on the plug support structure such that the PCB plug section abuts an upper surface of the support ribs.

5. The USB device according to claim 1,

wherein the plastic handle portion further includes a lower cover wall integrally molded to lower edges of the front wall, the rear wall, and first and second handle side walls, and

wherein the USB device further comprises a cover plate that is snap-coupled onto the plastic handle portion adjacent to upper edges of the front wall, the rear wall, and side handle walls, whereby the PCB body section is enclosed within the plastic handle portion.

6. The USB device according to claim 1, wherein the plug shell structure is metal and is molded onto the front wall of the plastic handle portion.

7. The USB device according to claim 6, wherein the metal plug shell structure includes a pair of mounting structures that respectively extend from the first and second shell side walls and are disposed inside the first and second handle side walls.

8. The USB device according to claim 6,

wherein the first and second shell side walls define engagement notches, and

wherein opposing side walls extending along the second end portion of the plug support structure include locking protrusions that are received in the engagement notches of the first and second shell side walls.

9. The USB device of claim 1, wherein the PCBA comprises a lead-free structure.

10. The USB device of claim 1, further comprising a light-producing device mounted on the PCB body section, wherein a peripheral wall of the handle portion defines a window aligned such that the light producing device is visible through the opening.

11. The USB device of claim 1, wherein at least one wall of the handle portion of the housing defines a key-chain hole for receiving a key chain therein.

12. The USB device of claim 1, wherein the PCB further comprises metal dividers formed on the upper surface of the PCB, each of the metal dividers being located between an adjacent pair of the metal contacts.

13. The low-profile USB device of claim 1, wherein the ICs include a wireless communication transmission device.
