A telecommunication socket structure including a rigid housing defining an internal cavity and at least one resilient arm disposed in the cavity near an opening thereof. The resilient arm has a free end formed with a first and a second projecting sections which are adjacent to each other. The first and second projection sections are respectively positioned in forward and backward positions in the cavity. The surfaces of the first and second projection sections are respectively inward and outward inclined. In case an incorrect smaller telecommunication plug is inserted into the socket, a straight stopper section of the first projecting section facing outward will stop the plug from entering the socket. When a correct larger telecommunication plug is inserted into the socket, along the outward inclined face of the second projecting section, the plug will gradually press the second projecting section to bias the free end of the resilient arm to outer side of the cavity. Therefore, the plug can be smoothly plugged into the socket.
