PURPOSE: A UIM card coupling device is provided to enhance space utilization of a PCB by separately installing a card holder for accommodating a UIM card from a port unit and installing only the port unit on the PCB. CONSTITUTION: When an impulsive force is applied to a card holder(100), a card holder connection recess(134) is released from a card holder connection protrusion(420) and the card holder(100) is moved to a front end portion along a card holder receiving recess(400). At this time, while a rotational shaft is moved to a slope portion of a movement recess, it receives a press-fit load in an axial direction, stores an elastic energy and is inserted in the axial direction. When the impulsive force is removed, the stored elastic energy is released, the rotational shaft is protruded in the axial direction and moved to a rear end portion of the card holder receiving recess(400) along the slope portion. Accordingly, the card holder connection recess(134) is positioned hear the card holder connection protrusion(420). In this state, the card holder(100) is rotated to lift up its real end portion and a UIM card(200) is inserted into the card holder(100). The card holder(100) is moved to the rear end portion along the card holder receiving recess(400) to insert the card holder connection protrusion(420) into the card holder connection recess(134), thereby fixing the card holder(100) to the card holder receiving recess(400).
