A connector for a displayed mobile device that is connected to a mobile device displayed in a store to supply power to the mobile device is proposed. More particularly, the connector for a displayed mobile device is usable for various types of mobile device. The connector includes: a charging cable having an insertion block, a connection terminal, and a screw hole; and a holder casing having a body, a support plate, and a long hole; and a fixing bolt fixing the insertion block of the charging cable to the body of the holder casing by being tightened and coupled to the screw hole after passing through the long hole. Therefore, an interval between the connection terminal and the support plate is adjustable.
