Patent ID: 8197273

Claim:
A German/French style plug with multiple pin arrangements, comprising: an outer enclosure, which has a side wall in which a plurality of slide channels is formed and a top wall adjacent to the side wall and forming a plurality of through holes, the outer enclosure forming therein a constraint rail; an inner housing, which is received in the outer enclosure and has a wall forming a constraint member that is matingly engageable with the constraint rail and also forms a constraint slot at a location close to the constraint member, the inner housing has a top forming a plurality of through openings, the inner housing forming a retention projection extending from an outer surface thereof; a stop plate, which is received in the outer enclosure and forms a retention trough in a portion projecting from a predetermined location thereof and engageable with the retention projection; a constraint plate, which is received in the outer enclosure and forms a plurality of constraint passages corresponding to the slide channels; at least one first plugging unit, which comprises at least one conductive pin receivable through the through holes; a second plugging unit, which forms at least one conductive pin receivable through the through openings and comprises a constraint section that is formed on a predetermined location of the second plugging unit to engage the constraint slot, whereby the second plugging unit is movable in a limited way as being constrained by the inner housing to exhibit difference in vertical positioning; and at least one third plugging unit, which forms at least one conductive pin receivable through the through openings.
