Why does the Lightning Connector have exposed pins?  Is there a risk of a short circuit if the pins are accidentally touched to the aluminum case on the ipad while inserting in the Lightning Connector port?  Are those exposed pins dangerous due to short circuit hazards?

iPad, iOS 6.1

    You always insert the Lightning Connector before you turn on power.

    I hope you mean that the Lightning cable doesn't connect power until it has exchanged a handshake with the device it is connected to---that's true.

     

    If you meant that one should 'turn off' the iOS device before plugging in the Lightning connector--that isn't necessary.

    I never turn off my iPad to plug in the 30 pin plug. I only make sure the wall socket is off.

    The OP was speaking of the Lightning connector and that's what I responded to.  The Lightning connector is pretty well protected against anything like a short.  If it weren't then Apple wouldn't have chosen a male connector with the tabs exposed.

     

    As far as that goes, I don't remember ever reading anything that indicates it is necessary to plug in one item--charger, cable, iOS device--before the other on either the 30-pin or the Lightning connector and I believe that if it were necessary Apple would have cautions all over the documentation.

     

    If you know of any such warnings--from Apple--I'd really like to have a pointer to one.

    Anecdotal evidence and not from Apple.

     

    I don't believe the connector is the source of that problem.  Now, if we find out that he somehow subjected the cable to a large static discharge that shorted out the protective circuitry then all bets are off, but that can happen to practically any electronic device controlling power flow. 

     

    The source of his problem could easily be from a bad charger that blew out the protective circuitry or even a high energy voltage spike that shorted it out.  I have tested my cable by shorting out all pins--no over heating resulted.

     

    Blaming the connector design isn't appropriate at this time.

    In the US, most wall sockets don't power off.
