I find that to get a tight crimp on the insulator so that it fits smoothly into the back of the DuPont shroud, after the first crimping action, I need to slide the connector in the crimper so that the insulation crimp is resting in the conductor crimp zone and hit it with a second squeeze.įor stripping wires, I like to use a tool made by OK Industries:
I’ve used a few for breadboards, but mostly, I use DuPont connectors for making pluggable connectors for PCBs – motor, power, sensor, etc, into the Berg headers. The link to the video has been replaced with a new video that provides much sharper images. With the wire already stripped and the tool holding the terminal snuggly, it is fairly easy to insert the wire into the terminal:ĭo take another quick look to verify the conductor is past the 2nd set of tabs before you squeeze the tool tight and finish the crimp. Now close the jaws just enough to hole the terminal in place: 1″ style terminals use the center crimp on the jaw): Here is the terminal in place in the tool with the tabs against the ridge (note that the. You are going to align the terminal such that the left side of the insulation tabs (using pic above) butt up against this ridge. Now note the ridge inside of the tool’s jaw. The bridge gives you a little slack so you don’t have to be too exact on where to cut the insulation: The very small set of tabs right before the bridge are not bent (at least not by this tool).įirst, prep the wire by stripping it such that the insulation is going to be grabbed by the first set of tabs and the conductor by the second. The far right tabs will attach to the insulation while the center set of tabs will attach to the conductor.
The crimper will bend two sets of tabs (though there are actually 3 sets). Here is an enlargement of a dupont terminal:

Rather than waste time trying to make another video that will almost certainly have the same issues, I will post a series of stills here which should make the process much clearer. Surprisingly, it has ended up being my top video. It seems it focuses at the start of the video and never again so close up videos like this don’t work well.Īdmittedly, I never really expected this video to be viewed by anyone but myself so I didn’t care. I use a lumix dmc-lx7 which is a great still camera. Update: I’ve had this for about a month now and have found multiple unexpected uses for it like building decent 9V breadboard connectors:Įveryone complains about the clarity of the video, and they are right – it sucks.
So I decided to post an instructional video of how I crimp the ends with success:

I had no luck finding an explanation on how to crimp the terminals onto the terminal and destroyed a few learning. I purchased male and female pins from pololu:
