Abstract:
1. An expansion module for fixing an interface card and electrically connecting the interface card to a main circuit-board, wherein the main circuit-board comprises at least one card slot corresponding to the interface card, the expansion module comprising: a transfer circuit-board, comprising an electrical connector disposed at an edge of the transfer circuit-board to be inserted into the card slot; an expansion slot, disposed on the transfer circuit-board and connected electrically to the electrical connector, wherein the expansion slot is for the interface card to be inserted into the expansion slot and electrically connecting the interface card to the main circuit-board; and a carrier body, providing an accommodating space to accommodate the interface card, and comprising: a bottom-plate, wherein the transfer circuit-board is mounted onto the bottom-plate and located in the accommodating space; and a lateral-frame extending from the bottom-plate to define the accommodating space between the bottom-plate and the lateral-frame; and a latch, pivoted to the lateral-frame and moving between a releasing position and a latching position, wherein the latch comprises a first clamping element, a pivoting piece, a first blocking piece, and a second blocking piece, the pivoting piece being pivoted to the lateral-frame, the first blocking piece perpendicularly extending from the pivoting piece, the second blocking piece perpendicularly extending from the first blocking piece and being perpendicular to the pivoting piece; the first blocking piece and the second blocking piece being used for respectively blocking two adjacent edges of the interface card, and the first clamping element being disposed to one of the first blocking piece and the second blocking piece, and at the latching position the latch clamps and fixes the interface card with the first damping element.
