An electronic device includes an enclosure body, a mounting apparatus, a securing apparatus, and a connector. The connector defines an engaging hole. The mounting apparatus includes a receiving housing and a first elastic member mounted in the receiving housing. The securing apparatus includes a sliding member mounted to the receiving housing and an engaging member. The engaging member is secured between the receiving housing and the sliding member. The engaging member is engaged in the engaging hole in a first position. The connector is received in the receiving housing and the first elastic member is compressed between the receiving housing and the connector in the first position. The connector moves out of the receiving housing from the first position to a second position when the sliding member slides relative to the receiving housing, to drive the engaging member to disengage from the engaging hole.
