Patent attributes
A positioning member for securing in position an add-on board is proposed, which is disposed inside an electronic device. The positioning member includes a coupling portion for coupling the positioning member to the inside of the electronic device, and a block portion attached to the coupling portion for preventing the add-on board electrically connected to a motherboard installed inside the electronic device from occurring any undesirable displacement. As the block portion is capable of being resiliently movable relative to the coupling portion, it allows the engagement and disengagement of the add-on board with the motherboard to be easily carried out without use of any auxiliary tool.
