Abstract
An electronic device includes a chassis. The chassis has a bottom wall and a rear wall, substantially perpendicular to the bottom wall. A motherboard is disposed on the bottom wall, and a riser card is perpendicularly connected to the motherboard. An expansion card is substantially parallel to the motherboard and coupled to the riser card. The expansion card has a first end and a second end, and the first end is secured to the rear wall. An airflow duct is located on the bottom wall of the chassis. A supporting bar protrudes from the airflow duct. A securing member is pivotably mounted to the airflow duct. The securing member includes a pressing plate. The second end of the expansion card is clamped between the pressing plate and the supporting bar of the airflow duct.
