Abstract

A USB bluetooth connector includes a shell that includes a front shell whose front and rear communicating with outside and a back shell integrated with the rear of the front shell. A printed circuit module received in the shell has a printed circuit board and a chipset disposed on the printed circuit board. The front of the printed circuit board has electric modules accommodated in the front shell for electrically connecting with corresponding conductors received in a USB interface. And an antenna circuit is etched on the inner surface of the shell and connects with the printed circuit module.
