be accepted by the fig1 female connector socket 100 there are a very large number of potential variations and possibilities so the examples shown in these drawings are only representative one can assume that an unauthorized or unlicensed hardware manufacturer would try to make his or her connector as different as possible from an authentic connector while still achieving electrical and mechanical compatibility elements of electrical and mechanical compatibility include for example proper electrical connection of most of the six electrical connections in the exemplary implementation at least data and clock line connections would presumably be wanted to provide electrical compatibility although the pluggable device might be able to provide its own power it would presumably also tie to the common ground connection or to shield but perhaps not to both and prevention or correction in some way shape or form from reversed orientation such that those lines are not reversed although in some circumstances one could envision simply telling the user to try it one way or the other until it works since there are only two possibilities so long as pin assignment is made carefully to avoid short circuits elements of mechanical compatibility depend to some extent on the particular application rugged locking conformal compatibility is probably useful for many applications however in applications where not much movement is involved then perhaps the locking mechanism could be dispensed with or not used and.
