Abstract: A shield is adapted be locked to a casing. The casing is formed with an inserting space, an opening, and two engaging holes. The shield includes a shell body, two engaging members and two biasing springs. The shell body is inserted into the inserting space, and shields the opening. The shell body includes a base plate formed with a slot, and two side plates each formed with a through-hole. Each of the engaging members is slidable relative to the base plate, and includes an engaging portion extending through the corresponding through-hole and releasably engageable with the corresponding engaging hole. Each of the biasing springs biases the corresponding engaging member to move in a direction toward the corresponding through-hole.

Abstract: An expansion card module for a server is provided. The expansion card module includes at least one expansion card fixing structure and at least one expansion card. The expansion card fixing structure includes a bracket, a supporting member, and a handle. The bracket is fixed to the server and includes a first protruding post. The supporting member is slidably disposed on the bracket. The handle is pivotably connected to the supporting member. The expansion card is adapted to be fixed to the supporting member. When the handle is pivoted to push against the first protruding post, the handle and the supporting member slide relative to the bracket so as to drive the expansion card to be plugged into the server.
