nostr:npub152jgfxwyqfpj5d448pq5sdevv37t66xshm8gpvkszp6kc0za7dyshftfmu why do all insulated crimp connectors suck so much? I know your follow up, yes I'm using the correct tool.
I've had enough fail I'm thinking of throwing them all away and switching to uninsulated and heat shrink.
Is it the right crimp connector for the cable area? (mm^2 or AWG) A connector for a larger area than is used can give a bad connection and/or slip off even if crimped with the right tool.
Is the tool of good quality? Some tools just don't work well, even for their intended use.
Many tools, particularly the better ones, are dependent on being used in the right direction - I recently made the mistake of putting the connector in back-to-front, and the cable slid right back out of the crimped connector.
Some tools have adjustment knobs, that need to be set to the right connector size, others have different slots for different sizes. Is it set/used for the correct connector?
Are the connectors good quality? Some connectors, particularly cheap ones, are the wrong size for their color code (if applicable), or not made to specifications.
That's all I can think of at the moment.
Uninsulated and heat shrink is good too, they can usually even be soldered.
I've run down that list and still have unpredictable results even with brand name connectors. The Chinese bulk variety pack I have is often better than TE. Or at least it bugs me less since it is cheaper to throw away the ones that won't crimp right.
Solderseal or powerpole are my preferred choices, but sometimes a ring terminal is what you need.
I have a dumb question, are you crimping at the right angle?
Assuming the right angle is a right angle between the connector and crimper and I haven't been misled my entire life, yes.
(you'll have to forgive me. I have a multi hour non electronics chore this morning because a pump seal I bought didn't come with instructions and every YouTube video about how to install it was wrong. Very aware that there is always more to learn and I might be wrong)
