If it?s crimped properly, everything is compressed together. Stranded
wire has gaps between the wires, but crimping closes those up. And the
connector is forced into the crevices between the strands. >
With a properly done crimp, I think the pressure should be enough to give a
cold wled between the wire and the terminal tag.
Perhaps the industries that stopped using
soldered connections in favour of
crimped did so because with hand-soldering, you can get variation (and also
of course bad solder joints), whereas with a crimp it's pretty uniform from
joint to joint?
Could be. Speed is also a likely consideration . And with crimp you
don?t have to worry about insulation damage due to heat.
Personally, i think if you gave the average car repair mechanic over here
a soldering iron, you've have holes burnt in the car seats within a few
minutes.
And if I
don't have such a tool? ?
Then you should solder things. Or get one. I finally broke down and
got a ratchet crimp tool. Spent $50 on it at least, probably a bit
more, but I have never regretted the investment.
$50 sounds rather cheap compared to what I've been quoted for a
good-quality crimp tool
I wonder if part of the differnece between 'reasonable' and 'top quality'
crimp tools is the hardness of the steel. Both will do good relaible
crimps when new, but the cheaper one wears out faster. And you don't know
this, but your crimps are getting ever less reliable. There would seem to
be no easy way to detect this
