No. Voltage has nothing to do with current rating.
Current ratings in connectors are usually (always?) based on temperature rise. For example, maybe the connector was tested at 5 Amps and it was found that after a long time, the temperature of the connector stabilized at 60 degrees in a 25 degree room, so this was declared to be the maximum allowable current. (I am just kind of making up numbers here to explain the idea.... these are not real numbers from a real connector).
However, if you know that your room will always be 10 degrees, maybe you can get away with running the connector at 6 Amps. Likewise, if you are only going to run 6 Amps for 5 minutes, then rest for 1 hour, maybe that is OK, too.
But doubling the current will probably cause the connector to overheat fairly quickly. So, the best thing to do is use the component within its published limits, or test it yourself to make sure it will work satisfactorily.
Connectors get hot because they have some resistance, R. The power dissipation in the connector is I2R. So doubling the current will quadruple the power dissipation and temperature rise in the connector (even more than quadruple because of the positive temperature coefficient of resistance).
So if a connector runs at 60 C in a 25 C room at 5 Amps (5 Amps -> 35 C temperature rise), then when you double the current to 10 Amps it will probably stabilize at over 165 C (10 Amps -> 140 C temperature rise). Unless the plastic melts first.
