I was wondering that, too. I've seen plenty of such sockets that have a
metal can on the inside of the case containing suppression components, and
have seen more than one fail - result being that the smoke works its way
out via the external power cord pins. It's so long since I've been inside
a DELNI that I don't remember if they have these (or if they're just a
plain ol' socket)
Also I
don't know why the socket shorted, if it *was* wet then perhaps I
could plug it in again, but I am very doubtful that this would be a good
idea. Should I just be thinking of replacing the socket?
Many "IEC sockets" are more than just sockets, and incorporate EMI suppression
components as well. The euphemism becomes "power entry module" instead
of "socket". The EMI suppression components (especially capacitors) in them
are
specced for AC line voltage applications and UL rated such, but they
still let out their magic smoke every so often :-). Even if it's just a socket, some debris can get in
there during storage, you
plug it in, the debris trips a fuse and vaporizes, and all you're left with is
a charred socket.
Maybe the power cord, even - damaged contacts or internal wiring, and
plugging it in shorted things out?
