Patent ID: 7403398

Claim:
A positioning member for securing in position an add-on board with a connection port inside an electronic device, comprising: a coupling portion for coupling said positioning member to a predetermined location inside said electronic device; and a block portion attached to said coupling portion and capable of being resiliently movable relative to said coupling portion wherein, when subjected to no external force, said block portion abuts against said connection port of said add-on board in a manner that said block portion stops said connection port from being withdrawn into an inside of said electronic device from an opening formed on said electronic device for exposing said connection port to the ambient, and said block portion and said connection port are arranged in a line parallel to a motherboard with which said add-on board is electrically connected, and wherein, when subjected to an external force, said block portion is moved to a position where said connection port is free from being stopped by said block portion, so as to allow said add-on board to be disconnected from said motherboard.
