[Elecraft] Anderson Powerpole connector

[Robert Harmon]

The only problem I have had with the Anderson Powerpoles is from my installing the connectors.
I will lose the 12 volts to a piece of gear and it always boils down to the same thing.  The leaf
didn't snap over the mating piece inside the connector.  Looking in at the end of the connector I can 
see that it didn't slide down completely.  If I can't snap it all the way in with my fingers I 
place the connector vertically on the bench and insert a small flat blade screwdriver and push down
on the edge of the leaf until it snaps.  Now I always check the connector after assembly to make sure
it has snapped in properly.

There are times when I thought I had it but I actually did not.  However, once I finally learned how to do it, everything works just fine with no heating and no significant voltage drop.  The connector has to snap in place into the housing, if it does not something is wrong.  Usually either the contact is upside down or the crimp or soldered connector became deformed.

Further, the contacts are well protected greatly reducing the chance of an unintended short. These features plus the fact that PowerPole connections are standardized and modular make them popular in EmComm and other field work, where equipment must be frequently assembled and disassembled in the field.  Life in the field is a great deal safer and simpler if everyone is using PowerPoles.  If you need to move your rig into someone else's vehicle, all you have to do is plug your equipment with PowerPole connectors into their PowerPole system.
