## Abstract

A mounting device for mounting an expansion card which forms a fixing piece at an end includes a rack and a frame detachably mounted to the rack. The rack defines two spaced recessed portions. Each recessed portion includes two opposite sidewalls and a bottom wall connected between the sidewalls. A resilient member is formed on each of the bottom walls. Two parallel tabs and a connection portion connected between the tabs are formed on the frame. The tabs are respectively received in the recessed portions and each abuts against one of the sidewalls of the corresponding recessed portion. The fixing piece of the expansion card is sandwiched between one of the tabs and the corresponding resilient member.

## Claims

### Claim 1

A mounting device for selectively mounting expansion cards with different lengths, each expansion card having a fixing member, the fixing member forming a fixing piece, the mounting device comprising:
a rack defining a plurality of spaced recessed portions each comprising two opposite sidewalls and a bottom wall connected between bottoms of the sidewalls, each bottom wall forming a resilient member; and
a frame detachably mounted to the rack, and comprising a plurality of first tabs respectively received in the recessed portions, and a plurality of connection portions each connected between two adjacent first tabs, each first tab abutting against one of the opposite sidewalls of the corresponding recessed portion;
wherein when an expansion card is mounted by the mounting device, the fixing piece of the expansion card is received in one of the recessed portions and pushed by the corresponding resilient member to abut against the corresponding first tab.

### Claim 2 (depends on 1)

The mounting device of claim 1, wherein a protrusion protrudes from each first tab to be engaged with the fixing piece of an expansion card once the fixing piece is received in the corresponding recessed portion.

### Claim 3 (depends on 1)

The mounting device of claim 1, wherein an L-shaped blocking portion is formed on the rack opposite to the recessed portions to detachably block an end of the frame opposite to the first tabs.

### Claim 4 (depends on 1)

The mounting device of claim 1, wherein each resilient member comprises a substantially C-shaped resilient portion defining an opening facing the corresponding bottom wall, a distal end of the resilient portion resiliently abuts against the corresponding sidewall of the corresponding recessed portion to sandwich the corresponding first tab together.

### Claim 5 (depends on 1)

The mounting device of claim 1, wherein each connection portion comprises a second tab parallel to the first tabs, and two extension tabs extending from opposite ends of the second tabs to be connected to the corresponding first tabs.

### Claim 6 (depends on 1)

The mounting device of claim 1, further comprising a switch member fixed to the frame, wherein the switch member comprises a circuit board, an expansion slot formed on a side surface of the circuit board to be electrically connected to the expansion card, and an edge connector formed on a bottom side of the circuit board.

### Claim 7 (depends on 1)

The mounting device of claim 1, wherein a holding piece is formed on the frame to hold the fixing member.
