Problems with auto crimp terminal connectors
robint:
Has anyone else had these infuriating problems I experienced. This refers to the common old type crimped auto connectors, I just took for granted till this pm I was faced with making a but splice with bullet connector pair having wasted time finding the crimp pliers didnt provide a reliable grip I soldered the wire in then I found that I could not get the bullet to plug into the female ferrule part, whatever I tried, the clearances were far too tight.
So this sent me on a a wild waste of time trying to source a proper set of auto style connectors (formerly a Lucas design). Fleabay was totally flooded with Cheap Charlie copies - 100's of listings of the same product - never got to a real product - total waste of time. Then I tried ggle - again Cheap Charlie in your face , but I found some wholesalers who then presented me with an incomprehensible array of proprietary design requiring me to drill down into spec sheets to find a compatible male/female pair of a basic auto connector - plus of course 10x price gouging unless MOQ 1000+
I am still flailing my arms around at this stupidly basic problem. You see male and female have to fit together due to accurate tolerance/dimensions. There is no real spring, its an interference fit - or else a sloppy fit
All those cheap kits you buy try seeing if you can make a reliable connected pair - I never trusted them, but only for 12V non critical use - and then soldered
What is your experience |O Am I going mad?

You mention bullet connectors, but show an image of spade/quick connect terminals. I hate bullet connectors, but never really had a problem with quick connect - although I rarely do in-line connections with them, almost always wire-to-board with PCB mounted terminals.
Yes, ebay, amazon, aliexpress is flooded with "cheap" terminals, and crimping tools. As with most items on these sites, they're not necessarily "bad" but its pot luck whether or not you get a decent one. For applications where its important, get branded terminals from reputable sources.
Don't solder crimp connections, its unecessary and can compromise the mechanical properties of the stranded wire, making it more likely to break where it flexes. If you want to splice using solder, then solder. If you want to splice using crimp, then crimp.
Are you asking about other types of connectors for in-line connections? Or are you splicing and want to know the best butt terminal, or crimp splice? Or are you after a relaiable and decent crimping tool for the terminals you pictured? It isn't completely clear what you're after.

for sure theses had quality gone down, all coming from oversea, i rely on usa stuff to get quality nowadays
metal is thinner for 15 amps ???

To this day, as far as I can remember, I've never once used those bullet connectors for anything. To me they are a waste of time and money. How many amps are going thru this pair I think I want to use? Uh - nope. I can't trust these to do what I want. :--

I got a used AMP 47386 from Ebay. It works well, at least for parts of the right size from their Plasti-grip or Pre-insulated Diamond Grip series.
