Patent ID: 7833028

Claim:
A wireless receiving and transmitting device having an exposed projection structure for user to hold, comprising: a casing unit having a casing; an antenna unit having an antenna module fixed in the casing; a substrate unit having a circuit substrate movably disposed in the casing and electrically connected to the antenna module; a projection unit having a projection element positioned on one end of the circuit substrate, wherein the projection element has a bottom portion selectively exposed outside the casing or hidden in the casing according to the move of the circuit substrate, and the projection element has a top portion always exposed outside the casing; and an electrical connector unit having an electrical connector position on another end of the circuit substrate, wherein the electrical connector is selectively exposed outside the casing or hidden in the casing; whereby, when the projection element is pushed towards the electrical connector, the bottom portion of the projection element is hidden in the casing and the circuit substrate far away from the antenna module by a predetermined distance in order to make a predetermined space near the antenna module and the electrical connector is exposed outside the casing; the user holds the exposed top portion of the projection element to electrically insert the electrical connector into a predetermined electronic device.
