A retaining mechanism for holding a circuit board and a related electronic device include a supporter, a first fixing component, a second fixing component and a third fixing component. The first fixing component is disposed on a supporting wall of the supporter, to buckle an edge of the circuit board and to constrain a movement of the circuit board in a first direction. The second fixing component is disposed on another supporting wall of the supporter, to contact against another edge of the circuit board and to constrain a movement of the circuit board in a second direction. The third fixing component is disposed on a base of the supporter. A holding portion and a hooking unit of the third fixing component respectively holds a bottom of the circuit board and inserts into an opening on the circuit board, to prevent the circuit board and the holding portion from separation.

A wedge lock clamping assembly, system and method wherein the module to be clamped in a slot in a chassis has a pair of wedge surfaces oppositely inclined to spaced-apart side surfaces of the slot. The clamping assembly comprises a pair of wedge elements on opposite sides of a movement axis and each wedge element is configured to be disposed within the slot between a respective wedge surface of the module and a respective side surface of the slot. An actuator operates to forcibly urge the wedge elements along the movement axis for causing the wedge elements to be wedged between the respective wedge surfaces of the module and respective side surfaces of the slot for clamping the module in the slot. A toggle is interposed between the wedge elements and the actuator for equalizing the force acting on each wedge element such that the wedge elements will move axially relative to one another to accommodate any difference in gap widths between the wedge surfaces of the module and side surfaces of the slots thereby to minimize any lateral shifting of the module relative to the slot while still securing clamping the module in the slot.
