Abstract: A male connector assembly is plugged into a female connector. The male connector assembly comprises a male-head connector and an antenna. The male-head connector comprises an electrical connection part and a covering body. The covering body is arranged at a first side of the electrical connection part. The antenna is arranged inside the covering body. The male connector assembly is connected to the female connector, and then the female connector transmits a wireless signal to the antenna. The antenna transmits a back-pass signal to the female connector after the antenna receives the wireless signal. Data is transmitted between the male connector assembly and the female connector when the back-pass signal is verified correctly by an electronic product electrically connected to the female connector.

Abstract: The invention relates to an outer type antenna structure comprising: a frame; an antenna arranged in the frame, the antenna extending to have a pin outside of the frame; and a connector. The antenna is integrated to the connector. The location of the antenna arranged in the portable electrically communicative device may be not limited so that the distribution of the antennas becomes easy. Therefore, the signal interference among the antennas can be reduced.

Abstract: An electronic exchange is applied for a portable electronic device is provided, which includes an exchange unit and a loading portion, which is provided for loading a SIM card. The loading portion is positioned in the portable electronic device. SIM card is electrically connected with the SIM interface of the portable electronic device. The exchange unit includes an antenna and an exchange module on the loading portion, in which the antenna is electrically connected with the exchange module. The exchange unit is electrically connected with the SWP pin of the SIM card, and is electrically isolated from the SWP corresponding contact of the SIM interface corresponding to the SWP pin.
