Hello All:

For quite some time at work I've noticed many of our newer 737s (circa 2010+), have the ground power port in a vertical position vs the older model 737s.. Can anyone explain why this is the case?

In Boeing speak, it was done to improve "External Power Receptacle Retention and Connectivity". There have been problems with the pins breaking on the new vertical connector, so from line #3852 they went back to the previous horizontal one until changes can be made. Eventually the new vertical connector will be offerred as a retrofit for all NG's.

And for any of those that have ever "plugged-in" in such a fashion, the reasoning behind the change is crystal.

To avoid the Cable + connector load bearing excessively on the plug point....A chain/cable to the lower end of the plug was used ending in a hook that used to hold the inner wall of the panel,This used to relieve the excess load.
