I think someone already mentioned doubling the stripped wire back over
the insulation, then putting that in the APP terminal. I'm pretty sure
that's what Anderson recommends. But then you have to PROPERLY crimp it,
not solder it. Do that and you won't need strain relief in ordinary service.
So treat yourself. West Mountain has an EXCELLENT crimper good for all
three APP terminals, and as quality crimpers go, it's dirt
cheap...$40...the price of two large pizzas. Anderson has one too, but
you need a credit check to buy it. I've done hundreds of crimps with the
West Mtn crimper for ham, auto and R/C use. Soldering APPs is ridiculous
and produces an inferior connection that NEEDS strain relief. You select
a stranded wire, then wick solder up it to make it a solid wire. That's
nuts.
I've heard from lots of R/C people that crimping makes an inferior
connection and the connection should be soldered as well. Tell that to
Mercedes or any quality auto or motorcycle manufacturer. Except for PC
boards, just try to find a soldered joint in an automobile of any
quality. You won't.
Everything is crimped. I don't know for sure, but I'd bet all aircraft
connectors are crimped. I bet the SR-71 connectors are all crimped.
Probably the Shuttle too. Shouldn't that be good enough for a 12 volt
ham rig?
Crimping isn't inferior. Crimping with crap tools is inferior.
Well, that feels better.

For the fine wires, before crimping I slide a short length about half
to 3/4 inch length of shrink tubing with a diameter just big enough to
fit over the crimped end on each lead then I slide another piece of
shrink tubing over both wires about 2 inches long and slide it out of
the way for now. once the crimp and soldering is done I slide
the short tubing so that it is just covering the crimp then shrink
it then I slide the terminals into the connector body and join the
two together and line them up. Then I slide the longer shrink that
covers both wires as close to the APPs as I can and shrink it. It
makes a tidy strain relief As a side note I never use the pins to
hold the connector pairs together I find that they can still come
apart Crazy glue does a much better and more permanent job.

Hi all,
I have recently converted more or less completely to Anderson Power
Poles
for all my power supply needs. I use an 8-way "hub" from Powerwerx as my
"distribution center". No fuses as the switching power supplies are
current
limited and probably failsafe in the event of most electrical component
failures. For the big stuff, radios with #12 power wires I am not
worried
about the lack of strain relief on the connectors. But for the flimsy
power
cables supplied with accessories like my KAT500, LP-100A, Lantronix
serial
servers I am. Has anybody found a good solution for this? Should I
just fill
the back of the connectors with epoxy or is there a better way?
