[Elecraft] More about Anderson PowePole connectors

[Sandy]

On the crimping vs. soldering thread for the Power Pole connectors....

I would be extra careful about putting them on with a torch.  It is very 
easy to overheat a pin this way.  Two things can ruin the metal connector 
being soldered on.  Too much heat can:
1. cause the plating to be damaged and increase the resistance of the 
mechanical connection.
2. Anneal the metal connector taking the stiffness or "spring" out of the 
metal, and cause poor contact an mating.

I usually crimp them because I happened to have a tool already that did a 
wonderful job.  This was an "AMP" number 29004-1 hand crimp tool.  Notch "G" 
works really great on the barrels of the pins commonly supplied with them. 
Also other notches of this tool will crimp MOLEX large and small pins well. 
Also it will do the usual red, blue and yellow barrel lugs too.

If you see one of these tools at a hamfest or want to buy a crimp tool, this 
one tool will do just about everything I have run across.

PS:  I hasten to add......Tyco-AMP makes an "imitation" of the Anderson 
Power pole connector.  My advice:  stay away from them.  The plastic 
housings and the inner contacts are shoddy compared with the Anderson 
product!
