The shell includes a power supply module configured to provide power to the data storages, and an adapter plate connected with the power supply module through a cable. The bracket is electrically connected to a connecting device. When the bracket is slid in the shell, the connecting device closely contacts the adapter plate to be electrically connected with the adapter plate, and the data storages are thus electrically connected with the power supply module.

Abstract: A server rack able to maintain electrical connections to its components during replacements includes a shell and brackets for data storage devices. The data storage devices are electrically connected to the bracket. The shell includes a power supply module and a connecting device electrically connected to the power supply module. The connecting device includes a resilient ring and a cable, one end of the cable is secured on the resilient ring, and the other end of the cable is electrically connected to the bracket. When the bracket is slid in the shell, the resilient ring elastically deforms to release cable or take back the slack cable, to maintain the electrical connections at all times.

Abstract: A server includes a main board, a side panel having an attached female connector, an expansion card, and a lever. The expansion card includes a latching member having a pivot and a male connector. The lever includes an engaging portion defining a slot, and a main body connected to the engaging portion and pivotally connected to the main board. When the lever is rotated in a first direction, the pivot is slid into the slot, causing the engaging portion to engage with the latching member. Further rotating the lever in the first direction, the expansion card is urged to move toward the side panel until the male connector mate with the female connector. When the lever is rotated in a second direction opposite to the first direction, the expansion card is urged to move away from the side panel, causing the male connector to disengage from the female connector.
