Connection assembly and electronic device using the same

An electronic connector connected to a print circuit board (PCB) includes an insulated body and a plurality of connection pins comprising connection ends. The insulated body defines a jack, the electronic connector further includes a communication board and a conductive pin module formed on the external of the insulated body. The connection pin is mounted between the insulated body and the communication board, and the connection ends are exposed from the jack. The conductive pin module includes a fixing frame positioned at the external of the insulated body and an elastic sheet fixed on the fixing frame. The elastic sheet is mounted on the communication board and communicates with the PCB, for allowing the PCB to electronically connected to the connection pins.
