An electronic device includes an enclosure, a connector, a connector cover, and a resisting member. The enclosure defines at least one opening. The connector is disposed in the enclosure and corresponding to the at least one opening of the enclosure. The connector cover covers the opening to protect the connector and includes pivot shaft. The pivot shaft is rotatably connected to the enclosure. The resisting member elastically resists against the connector cover. The resisting member may be formed by a spring biased block that presses in an end of the pivot shaft to maintain the cover in open or closed position. A restricting member may be located in the opening to limit cover rotation in both open and closed positions.
