USB application device
First Claim
1. An USB application device, comprising:
- a casing;
a printed circuit board completely received in the casing and comprising a top surface and a bottom surface opposite to the top surface;
a plurality of electrical elements disposed on the bottom surface of the printed circuit board;
a plurality of contacts disposed on the top surface of the printed circuit board;
a first supporting portion received in the casing and located between the bottom surface of the printed circuit board and the casing;
wherein the first supporting portion supports the printed circuit board, which is in front of all the electrical elements and abuts against up front one of the electrical elements disposed on the bottom surface of the printed circuit board;
wherein the casing has a housing and a shell coupled with the housing, the printed circuit board has a front end portion and a rear end portion opposite to the front end portion, the contacts are disposed on the top surface of the first end portion of the printed circuit board, the rear end portion of the printed circuit board is received in housing, the contacts is exposed outside the housing and received in the shell, the first supporting portion supports a central portion of the front end portion of the printed circuit board;
wherein the housing has a bottom wall, a top wall opposite to the top wall and opposite side walls, each of side walls has a first portion and a second portion, the first portions of the side walls respectively connect to opposite sides of the bottom wall and the top wall to surround a rear receiving space for receiving the rear end portion of the printed circuit board, the second portions of the side walls only connect to the bottom wall to form a front receiving space for receiving the front end portion of the printed circuit board and the first supporting portion, the contacts are exposed outside the front receiving space and received in the shell covering the second portions of the side walls;
wherein the first portions are higher than the second portions.

Abstract
An USB application device includes a casing and a printed circuit board received in the casing. The printed circuit board includes a top surface disposed a plurality of contacts, and a bottom surface disposed a plurality of electrical elements. A first supporting portion is received in the casing and located between the bottom surface of the printed circuit board and the casing, which supports the printed circuit board and is in front of all the electrical elements and abuts against up front one of the electrical elements disposed on the bottom surface of the printed circuit board. Therefore, the first supporting portion supports a central portion of the printed circuit board to resist an external pressing force in order to prevent the printed circuit board from damage. Furthermore, the first supporting portion positions the printed circuit board during the fabricating procedure of the USB application device.
