This is why everyone says crimping is the way to go.
No not everyone. I say crimping is the way to go because the end result is a low ohm, permanent connection that cannot fail without aggressive destructive intervention.
What about coating the bare strands with some oil or other anti corrosive treatment and just crimp no solder? Would dielectric grease be useful in this case?
Dielectric- the “die-“ part means it’s resistive to electrical conductivity. You want clean, dry crimps. Use dielectric grease or fluidfilm
after the electrical connection is assured to lock out oxygen on the exposed area
What’s dangerous about this kind of crimp?
It is not 100% contact over the full body of the terminal cavity. Higher ohms; resistance makes heat, heat causes fires. Never mind poor performance- at the price of copper just spend it and do it right.
I mean there are hammer style crimpers, what’s wrong with this redneck version
The hammer-style crimpers are dubiously effective on just one or maybe two sizes of terminals. Plus, the die crimpers have a huge advantage (that is marginally the reason why the hammer crimpers sortof work dubiously for 1ga, 1/0ga, and 2/0(barely)): they swage the fitting barrel
smaller than its manufactured shape and size. The hammer crimp
crushes the fitting even sometimes stretching it. This is not 100% contact. When I use the hammer crimper I actually crimp in a few ‘stages’ to theoretically force the fitting to fold in itself before finally crushing it shut making a swage-like fit. But it’s not ideal for sure.
you've spent thousands of dollars, maybe tens of thousands of dollars and you're going to trust the most important connection in your entire system to some random screws and a sledge hammer head you found laying around
That is the best summary comment on this thread
While you can justify it to yourself to not accept a standard, SOP or best practice; the end result may not be safe, have longevity, satisfaction and long term economic value
As above!
struggling with the thought that a soldered joint isnt as good as a crimp. More contact area with solder.
Contact area is great; low resistance is another leg of the three-legged stool
never thought about (marine grade/glue lined) heat shrink helping keep moisture and air out.
Imho that is the primary reason to use it
I like the closed end, and with a shrink wrap on there they are well sealed
Because you like stuff done well
with a die that's just slightly too small is the creation of some 'wings' on the sides of the crimp where the two halves of the die meet. Shrink and perhaps a gentle filing to remove any sharp edges would fix that.
I seldom crimp in one stroke, but I start the swage, and rotate 90* and even ‘odd’ fittings don’t get the wings.
I’ve always been an annoying advocate of 100% contact. A former employer was irritated that I didn’t use the heat-shrink crush crimp terminals but used bare crimps and heat-shrinked over that. But with winter road salt and summer CaCl on dirt roads I learned a long time ago what worked. Years ago a broken spring event wrecked a boat trailer’s wiring and I quick fixed it roadside with a piece of extension cord and bare crimp butt-connectors, and heat shrink over. It’s been 15 years of a lot of wet cycles and it’s still going well-I never “fixed it.”
