Abstract

An expansion card frame assembly is configured to support a riser card and an expansion card. The expansion card frame assembly includes a frame, a pivotable component and a stopper. The frame is configured to support the riser card, and the expansion card is configured to be inserted into the riser card. The pivotable component is pivotably disposed on the frame and configured to be located aside the expansion card. The stopper is movably disposed on the pivotable component and configured to be located at one side of the expansion card which is located farther away from the riser card.

2 . The expansion card frame assembly according to claim 1 , wherein the stopper is slidably disposed on the pivotable component so as to be slidable between a first position and a second position; when the stopper is in the first position, the stopper is configured to be located at one side of the expansion card of full height which is located farther away from the riser card; when the stopper is in the second position, the stopper is configured to be located at one side of the expansion card of half height which is located farther away from the riser card.

3 . The expansion card frame assembly according to claim 2 , wherein when the stopper is in the first position, the engagement protrusion of the stopper is engaged with the first engagement hole of the pivotable component; when the stopper is in the second position, the engagement protrusion of the stopper is engaged with the second engagement hole of the pivotable component.

4 . The expansion card frame assembly according to claim 3 , wherein the straight line is configured to be located farther away from the expansion card than the pivotal axis of the pivotable component.

5 . The expansion card frame assembly according to claim 3 , wherein the pivotable component has a guide slot, and two opposite ends of the guide slot respectively communicate with the first engagement hole and the second engagement hole.

6 . The expansion card frame assembly according to claim 3 , wherein the stopper further has an opening and an elastic arm, the elastic arm is movably located in the opening, and the engagement protrusion is located on the elastic arm.

7 . The expansion card frame assembly according to claim 1 , further comprising a positioning component, wherein the positioning component is fixed to the frame, the pivotable component has a curved slot, and the positioning component is partially located in the curved slot.

8 . The expansion card frame assembly according to claim 1 , further comprising an elastic engagement component, wherein the pivotable component has an opening, the elastic engagement component is fixed to the pivotable component and is partially located in the opening, the frame has an engagement hole, and the elastic engagement component is detachably engaged with the engagement hole.

9 . The expansion card frame assembly according to claim 1 , wherein the pivotable component has a contact structure, the contact structure and the stopper are configured to be located at two opposite sides of the expansion card, and the contact structure is configured to be in contact with the expansion card.

10 . The expansion card frame assembly according to claim 1 , wherein the frame further comprises a positioning portion, the positioning portion is connected to the front frame portion and extends towards a direction away from the second side, the positioning portion is configured to support the expansion card.

11 . An expansion card module, comprising:

an expansion card frame assembly, comprising:

a stopper, movably disposed on the pivotable component and located opposite to the side frame portion;

a riser card, supported by the side frame portion of the frame; and
