This question is a great example of why using terms properly can be
important.  Current goes thru things, voltage can be accross them.  Voltage
thru something is just gibberish.

A connector is intended to have as low a resistance as possible.  It will be
designed to carry some maximum current.  The voltage accross the connector
at any time is the current thru it times its resistance.  Ohms law states
that V = I * R.  If R is fixed as it is with a connector, you only get to
pick one of V or I.

The voltage spec of a connector refers to the open voltage or the insulation
voltage between adjacent pins or to some other point.

I don't see how you can answer a question that doesn't make sense in the
first place.

A good explanation requires a good question.
