MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS ## Abstract An AC (Alternating Current) plug for providing power via a power circuit is assembled by: selecting a cover that includes prongs and structures on an inner side; positioning a PCB (printed circuit board) that includes contact pads connecting the PCB to the power circuit on structures of the inner side of the cover; positioning the spring mounted terminals on structures on the inner side of the cover such that a first end of each spring mounted terminal is positioned on a contact pad of the PCB; positioning a cap on the spring mounted terminals, the PCB and the cover, such that assembly holes of the cap, the PCB and the cover are aligned; and fastening the cap to the cover, such that the first end of each spring mounted terminal is secured against a respective contact pad and each spring mounted terminal is loaded and exerts a force against a prong. ## Claims ### Claim 1 An AC (Alternating Current) plug for providing power, the AC plug comprising: a cover comprising a plurality of prongs; a PCB comprising a plurality of contact pads; a plurality of spring mounted terminals; and a cap fastened to the cover, wherein the fastening of the cap secures a first end of each spring mounted terminal against a contact pad of the PCB, and wherein the fastening of the cap positions each spring mounted terminal for contact with a prong of the plurality of prongs. ### Claim 2 (depends on 1) The AC plug of claim 1, wherein the fastening of the cap connects the prongs to a power circuit via the contact pads. ### Claim 3 (depends on 2) The AC plug of claim 2, wherein no wires are included in the connections between the plurality of prongs and the power circuit. ### Claim 4 (depends on 1) The AC plug of claim 1, wherein the cover comprises a plurality of slots, and wherein the each of the plurality of prongs are foldable prongs that may be rotated into a slot of the cover. ### Claim 5 (depends on 1) The AC plug of claim 1, wherein the plurality of prongs are fixed to an outer side of the cover. ### Claim 6 (depends on 1) The AC plug of claim 1, wherein the spring mounted terminals are positioned based on an alignment of a second end of each of the spring mounted terminals with an alignment structure of the cover. ### Claim 7 (depends on 4) The AC plug of claim 4, wherein each of the plurality of prongs comprises a cam that contacts a spring mounted terminal when the foldable prongs are rotated to an extended position. ### Claim 8 (depends on 7) The AC plug of claim 7, wherein the cam of each of the plurality of prongs does not contact the respective spring mounted terminal when the foldable prongs are rotated to a folded position. ### Claim 9 A method of assembling an AC (Alternating Current) plug for providing power, the method comprising: selecting a cover comprising a plurality of prongs; positioning a PCB on an inner side of the selected cover, wherein the PCB comprises a plurality of contact pads; positioning a plurality of spring mounted terminals, wherein a first end of each spring mounted terminal is positioned on a contact pad of the PCB; and fastening a cap to the cover, wherein the fastening secures the first end of each spring mounted terminal against a contact pad of the PCB, and wherein the fastening positions each spring mounted terminal for contact with a prong of the plurality of prongs. ### Claim 10 (depends on 9) The method of claim 9, wherein the fastening connects each of the prongs to a power circuit of the PCB via contact with a spring mounted terminal that is fastened to a contact pad of the PCB. ### Claim 11 (depends on 10) The method of claim 10, wherein no wires are utilized to connect any of the plurality of prongs to the power circuit. ### Claim 12 (depends on 9) The method of claim 9, wherein the cover comprises a plurality of slots, and wherein the each of the plurality of prongs are foldable prongs that may be rotated into a slot of the cover. ### Claim 13 (depends on 9) The method of claim 9, wherein the plurality of prongs are fixed to an outer side of the cover. ### Claim 14 (depends on 9) The method of claim 9, wherein the cover is selected from covers comprising prongs conforming to electrical outlets used in different geographic regions. ### Claim 15 (depends on 13) The method of claim 13, wherein each of the plurality of prongs comprises a cam that contacts a spring mounted terminal when the foldable prongs are rotated to an extended position. ### Claim 16 (depends on 15) The method of claim 15, wherein the cam of each of the plurality of prongs does not contact the respective spring mounted terminal when the foldable prongs are rotated to a folded position. ### Claim 17 An AC (Alternating Current) adapter for providing power to an Information Handling System (IHS) via a power circuit, wherein the AC adapter comprises an AC plug comprising: a cover comprising a plurality of prongs; a PCB comprising a plurality of contact pads; a plurality of spring mounted terminals; and a cap fastened to the cover, wherein the fastening of the cap secures a first end of each spring mounted terminal against a contact pad of the PCB, and wherein the fastening of the cap positions each spring mounted terminal for contact with a prong of the plurality of prongs. ### Claim 18 (depends on 17) The AC adapter of claim 17, wherein the fastening connects the prongs to a power circuit via the contact pads. ### Claim 19 (depends on 18) The AC adapter of claim 18, and wherein no wires are included in the connections between the plurality of prongs and the power circuit. ### Claim 20 (depends on 17) The AC adapter of claim 17, wherein the cover comprises a plurality of slots, and wherein the each of the plurality of prongs are foldable prongs that may be rotated into a slot of the cover.
