Crimping DuPont Connectors
HTML-код

- Of all the connectors I’ve had to make, by far the most frustrating to learn were the DuPont connectors. It took a while for me to figure out where I was going wrong, but once I figured it out, making them got to be a breeze. For something like an R2D2 build, learning to make DuPont connectors is crucial for wiring the servos, the Arduino and all the other microcontrollers used throughout the droid.
I watched numerous other videos when I was trying to learn to make these connectors, but none of them really addressed the specific issue I was encountering, and many even suggested using a sharp implement to help “push” the wire into the connector! What I have learned since then is that unless you are using a thicker gauge wire, you should NOT need any implement to help insert the pin. If you are having difficulty, inspect your crimp and look for damage that is likely causing the problem.
The exact connector kit that I got from Amazon is no longer available, but there are plenty of them to choose from. In addition to the connector pins and housings, be sure to get a decent ratcheting crimper if the kit doesn't include one.
Good explanation. In many parts of the world the term "Dupont" is not used. Usually these are called uninsulated terminals. I've even heard fold over terminals used to describe them.
I wasn't aware of that. Very interesting, thanks for sharing!
Good video. These are much easier than the really tiny JST pins.
thanks so much - totally saved me A LOT of time and frustration. I finally got a pair of crimpers and thought I'd lost my mind till I watched your guide.
Excellent video . At last a clear concise explanation with good close ups.
There are crimpers available that have a spring loaded blade that locates between the bare wire tabs and the "wings". This will locate the connector pin in the correct place for crimping. Down side is, they are usually expensive.
You have a place in the heaven! Thank you very much for this wonderful explanation!
I just got one of these kits. Did not come with any directions. I figured it would be simple. I have destroyed several pins trying to figure it out. Perfect timing that your video popped up in my feed. Thanks for the great tips.
Man I could’ve used this video a few days back! I believe I have the exact same DuPont connector case and crimper tool! It was a nightmare with some of the connection and I ended up having to over crimp them to keep the wire from sliding out! Either that or the end wings for the wire sheathing would not crimp enough and then wouldn’t slide into the connector. So I’d squeeze those shut with needle nose to fit. EST breakdown I’ve seen on these connectors. Thanks for making the video!
Excellent video! I use mini-pliers to snug the insulation wings around the wire insulation, which "locks in" the positioning of the wire before putting the assembly into the crimp tool.
I've started doing exactly that, too! I recently made a boat load of servo extension cables and every one came out fine. I often don't strip as much insulation as shown in this video - perhaps I'll post an update soon with the extra tips. Thanks for watching!
Perfectly clear instruction. Thank you for sharing your experience. Very useful.
Fantastic video, exactly what I was hoping find - thank you
Thanks for the clarification. I‘ll now try again.
Great close-up tutorial. I have just started crimping and my first dive into the process involved crimping the mx1.25 connectors which are tiny. Using a lit desk mounted magnifying glass is a must as my old eyes need a little help to check those little tabs are far enough away from the crimping process. One thing that helped was to ever so gently close the butterfly ends to be u-shaped rather than v-shaped which allowed me to more easily fit the tiny connector in the crimping tool. I uses an IWS3220 which seemed to work ok.
Thanks! Magnifying lenses are a must, and thicker wire makes things easier, too. Since recording this video, I've shifted to stripping less insulation off the wire (especially when crimping the female connectors) and I also find that pre-bending the butterfly ends tighter to the wire helps keep things stationary when crimping.
It seems my issue , after watching this video, is the crimper which came with a kit, and I thought I was doing it wrong.The labels on mine are .25mm .5mm and 1mm. Using the .5, there is not enough crimp, and the wire comes out easily. Using the .25, the crimp on the insulation area is too much, pressing down in excess causing the insulation to flatten, and thus cannot fit inside the connector.
Sometimes if the crimp flattens the insulation too much, you can take some pliers and squeeze it back into round and it will slide easily into the housing. It's a shame that so many of the crimpers out there are not exactly up to spec.
Thank you for the great video.
Thanks for the video. I have a bunch of pre-made ones I got from Amazon, but they don't seem to stay on the pins for NodeMCU boards. If you don't mind answering me, since you have the experience here, am I doing something wrong and/or any advice for me on that front? The goal is to connect LEDs to the NodeMCU using (what I think is) 18 awg pre-made wires. Thanks again!
Oh, so sorry I didn't see your comment sooner. The connector should provide a reasonably tight connection - there should be no danger of it falling off. Chances are you aren't doing anything wrong - the pins and connectors are all a standard size, and if the pre-made connectors aren't gripping the pins well, it might just be a matter of poor construction. I have a love/hate relationship with Amazon - there are good deals to be found, but quality is hit or miss. I think that's a big reason why I prefer to just make my own - I can inspect each crimp and test the connectors before moving on. It takes some time and practice to get the hang of it, but it's worth it in the end. Good luck with your project!
Can you send me the crimping tool link ? I want to buy it for awg22 wire
This is the one I have: www.amazon.com/gp/product/B00OMM4YUY but as I mention in the video, the crimper die is "wider" than the area that I actually want to crimp - so if you decide to use this one, be very careful to position the wire correctly to avoid damaging the little prongs that stick up close to the connector end.
where to get this cimper
The exact crimper I got is no longer available, but there are tons of identical options out there. You should be able to search for "ratcheting dupont crimper" and see lots of results for SN-28B dupont crimpers. For around $20 you can get a crimper and a decent supply of pins and housings.
Do have a link for the Bluetooth dongle?
www.amazon.com/gp/product/B002AQSTXM This is the one I got, but that was nearly 3 years ago. The main thing was to get one that had a decent range - this one will go up to 100 meters, which at this point is WAY farther than I'll ever be from my droid.
Thank you
Never understoood why people have problems using crimpers for jst/dupont style connectors , it's a simple case of observation to the connecteor when inserted into the crimp anvil jaws .......
and you got wrong crimped dupont as result wrong crimper using :)
huh?
