Methods of assembly are provided for an AC plug supporting foldable prongs. The AC plug includes: a cover including slots and prongs. In an extended position, the prongs are insertable in AC outlet receptacles and each prong contacts a spring mounted terminal that is coupled to a power circuit. In a retracted position, each prong is recessed in a slot of the cover and does not contact a spring mounted terminal. In the extended position, the coupling between each prong and the power circuit does not utilize wires. A first end of each spring mounted terminal is positioned on a contact pad of a printed circuit board (PCB) that connects the AC plug to the power circuit. A cap is fastened to the cover and secures the spring mounted terminals to the respective contact pads and secures the PCB and spring mounted terminal to the cover.
