Could be the tool. How many pliers have you tried so far?
- sigstoat 6y ago
  zero.

    You can buy cheap crimping pliers on banggood, but check the reviews first (e.g. youtube).

      hmm, i thought you were implying that i was using pliers to crimp them, instead of actual crimpers. (which would've made you a jerk, which is why i didn't elaborate much further.) instead it looks like you call them "crimping pliers" instead of "crimpers" (or perhaps "crimping tool") like most american english speakers. fair enough. looking very quickly at some youtube videos, i appear to have something similar to the cheap ratcheting chinese crimpers, not the (apparently) popular and non-ratcheting japanese crimpers. i'll pick up the different tool and see how it goes. ...i've still got hundreds yet to go, so it'll have plenty of time to pay for itself.

      Those crimping tools are usually good enough for male pins, but they make a mess out of female pins. They just don't come out square enough.

        You have to be careful not to damage the square part when crimping. Some have a little tab that give a guide how far you can push it in to the tool without damaging it.

Just get the 63811-1000 and be done with it. This will suffice for 99% of open-barrel long-crimp terminals you'll ever encounter. (For short-crimp stuff like JST PH, look at the Iwiss 2820M.)

  > 63811-1000 Expensive for two pieces of die cut steel, but I can confirm they've worked well for me on a variety of terminals, including automotive stuff.

These tiny connectors absolutely must be used with a proper crimper. http://www.mattmillman.com/info/crimpconnectors/dupont-and-dupont-connectors/ http://www.mattmillman.com/info/crimpconnectors/dupont-and-d...

Investing the money in a proper crimp tool helps a LOT with these fiddly little buggers. I've got a nice set of interchangeable crimp dies that go with one of two different sized crimpers, ( Its from the same ODM/manufacturer as this tool set https://www.altronics.com.au/p/t2177-crimptool-ratchet-multi-connector-universal-kit/ https://www.altronics.com.au/p/t2177-crimptool-ratchet-multi..., I just collected my own set from several different stores because I wanted a different set of crimp dies) and while I can crimp right down to these sorts of small connectors... the moment I have any problems or it doesn't crimp right first time I'll put down my big crimp tool, and swap over to the little crimp tool I have thats specific for these darn things, pretty sure its this one, https://www.altronics.com.au/p/t1537-crimptool-telephone-terminal-20-28-awg/ https://www.altronics.com.au/p/t1537-crimptool-telephone-ter..., I've had it so long I've forgotten which model it is. While having good tools helps, they are still a PITA, just no longer a RPITA.
