Soldering after Crimping

[kd1na]

If you have the proper crimping tool for Anderson Power Pole connectors ( not the cheap $30 Pair but the $50 or more pair with ratchet locks) the crimped connection should not be soldered.  Soldering the crimped pin results in solder wicking back up into the wire melting or damaging the insulation and causing the wire be very stiff at the point of entry in the Anderson pin. This could result in failure of the connection after some use.

If you don't have the proper crimping tool you must solder.

This may be a dumb thing to do, but after crimping (using the more
expensive ratchet type crimper) and inserting the connectors into their
housing, I run some hot melt glue around the conductors where they enter
the housing.  This IMHO provides support to the conductors where flexing
may tend to cause failure after a time.

I would be pleased of anyone could provide reasons why this is a stupid
idea to put their argument on the reflector.  We learn by mistakes and
by discussion!

That's been suggested before and as long as it doesn't stop the slight  
movement of the contacts, is ok.

   At the W1KM station we have had Anderson PowerPole connectors in
service for about 4 years.  All were installed with the proper crimping
tool.  The crimps were not soldered.

   We are starting to see some increase in resistance on some of the
connections, and have speculated that some oxidation is occurring inside
the crimped bundle of wires.  Typically 5 connections exist between
source and sink:
   -- inside the power supply, between the board's wiring harness and
the external terminal.
   -- between the supply's external terminal and a cable run toward the
operating position.
   -- at the other end of this cable run, where it connects to a
RigRunner (PowerPole).
   -- at the start of a second cable run, where it connects to the
RigRunner.
   -- at the other end of this second cable run, where it connects to
the radio.
The resistance of these connection, plus cable resistance and current
draw, determine the voltage drop between supply and the radio's connector.

   To me, it seems a reasonable precaution to allow solder to be wicked
up into the crimp from the front (not the rear) of the PowerPole pin.  
Properly done, this does not melt insulation nor cause the wire outside
the housing to stiffen.
