Crimping dupont connectors is among the most frustrating things in this life. The designers clearly revel in the sorrow of others. You sir, are a brave soul for taking this on!

sOMEtimes when i cANt fall asleep I put this video on

I used to work for an electronics manufacturer who had all the proper tools worth thousands of dollars. They could crimp a perfect JST, Molex, or Dupont in a fraction of a second. When I got into drone / 3D printer building, I was incredibly frustrated that a single connection could take me up to 5 minutes...and usually fail. It is definitely an exercise in skill, patience, and crafting new swear words for the DIY community. Thanks for sharing your technique.

Thanks for this - worked perfectly ! Especially making sure only about 1.5 mm of wire is stripped - less is more in this case. One trick I can add - use an ultra small dab of super glue on the insulation to pre-glue the contact onto the wire to hold in place, then crimp it.

Thanks for making this video.
I went from not not being able to open the crimpers to immediately making a successful joint after watching you. The instruction that came with my tool were a waste of time. Your guidance was brilliant.

[davidattenberg]

So, after messing-up several Dupont's, I was watched several videos on proper crimping techniques. Your video was the one that got me on the right track.
Thanks!

I've had to refer to this video multiple times over the years, LOL. About every other time I need to do this, I forget how the heck it works. Thanks.

Want to thank you a ton for this video. Helped immensely. I want to add that if you clip the pin off the string of pins at the strap part, it can become a tab that sticks out a bit and stops you from pushing the pin too far into the tool. Then you can just break it off after you have made the crimp.

Thanks... You saved my bacon! I´ve spent almost 2 months on-and-off trying to get my connectors to work (yes Dupont) one´s... After watching your video carefully, I realized I was using my crimpers the wrong way and ended up having to use long-nose pliers after to finish the crimp. Just so you know, I was crimping 18-Pins at a time, male and female ones, hence why I kept walking away from the job when it didn't quite work out. But now that I have seen your video, the jobs a good´n! So thanks again, as I was trying forever to wire up my 3D printer and cable managing it all to perfection!!

I really like the slow treatment on this video and the trial-and-error quality of the instruction. It all helps towards familiarizing the tool and procedure. Very nice!

This is like watching grass grow, but the best grass grow video yet!! Thank you for sharing this. Great camera work, considering the subject.

I honestly suggest 2 - 3 clicks on the next size up, and that'll close the wings just enough where you can slide your wire in and then guide it in the rest of the way to finish the crimp. Loading the wire in first (outside of the tool) is the fastest way I've found of doing this.

[randychapman]

Thank you, this really helped! I would suggest one change that was much easier for me, especially since my wires i'm working with have oddly thick insulation. Use a pair of needlenose pliers to hold the connector by the wing, place the wire in it, then tighten the wing just enough to be snug -- this will take care of the problem you were facing with the connector not fitting in the right slot, and the wire is so much easier to place when you can see it. After the wings are snug, it can be put in the right slot of the crimping tool, and crimped right up perfectly :D

Watched two other videos do it completely different and it was taking me forever to do just one. Watched this one and all my wiring was done in minutes. Thank you!

[jrwaters]

I liked the extra context you provided. There are short videos out there already that leave out details that I personally (being a noob here) needed. Thank you.

I like Gary Myers' idea of the header jig. However, I found that the thumbnail trick works very well. I have exactly the same sort of crimp tool and I have found that you can crimp all the way down on the largest gap to pre-form the back part of the pin and then immediatly move to the smallest crimp to set up for the cable. I got this down to a fine art crimping 20 breadboard power leads for a school I volunteer at! :-) Also, if I press all the way down in the smallest crimp, the pin gets jammed in and is hard to release. So I crimp down just enough and then spring it with the release trigger. It just takes a little practice to know how far to go. Many thanks for the video. It saved a lot of hair pulling!

In a factory somewhere there is probably a machine that does the entire operation in two steps, ten in parallel and ten per second. That is amasing enough but someone designed that machine and got it working. Automation is awesome.

I appreciate you taking the time to make this detailed tutorial, I watched it the other day and so when my pair of these crimpers arrived today I was able to use them perfectly straight away. Thanks very much, you’ve no doubt saved me lots of experimenting and swearing!

[chuckmorgan]

Thanks...
I've been having 1 out of 3 to 4 successful crimp.
NOW, I very seldom have a bad crimp thanks to you and your video..

[tommyong]

Thanks for a thorough tutorial. I haven't done any crimping work, as a first timer this video taught me a lot.
