Abstract: A device for mounting a hard disk in a server or other housing includes a frame, a hard disk, and a rotatable element. The frame defines a receiving space thereon and includes an end wall. The hard disk is slidably received in the receiving space. The hard disk includes a fastening element facing to the end wall. The hard disk is slidably attached to the end wall and the fastening element is locked to the end wall. The rotatable element is attached to the end wall and can rotate from a first position to a second position to abut the fastening element. The rotatable element can be pressed against the fastening element to unlock and the hard disk can be slidably detached from the end wall.

Abstract: A server includes a substrate, a circuit board and a locking device assembling the circuit board to the substrate. The locking device includes a frame and a sliding member. The frame includes a pin having a main body and a hood wider than the main body. The sliding member defines a latching groove and a sliding groove therein. The latch groove includes a circular hole facing the sliding groove and a slit narrower than the circular hole. The sliding groove includes an opening facing the latch groove and a split. The opening is wider than the hood. The split is narrower than the hood but not narrower than the main body. The hood extends through the opening of the sliding groove. The sliding member moves relative to the frame along a first direction to cause the main body of the pin to engage in the split of the sliding groove.
