Glad it helped. That's exactly why I made the video. Information was hard to find on using these and once I figured it out I thought I should share it. :)
This was such a well explained video. One of the best diy videos period. Use of product names, step by step instructions, explanations, great visuals. Thank you!
This is EXACTLY what I've been looking for over the last 18 months to make my own RGBW extensions for LED lighting. Thank you and brilliantly explained.
Think I must've tried making these connectors at least 70-80 times and never once got it absolutely right. Your video was absolutely on the mark, amazingly short and got the connector right the very first time! Thanks!
Grrrrrrrr, why didn't I find you last year. I bought one of these to help me with a project that I parked as I couldn't find a help file or decent how to video till now. The irritating part is you had already made this wonderfully insightful and easy to follow video. I have now saved this so that post crimble I can return to the project dust if off and try to move forward. Many Thanks Lewis, your projects are ones I will look to emulate and shamelessly use.
Thank you! One of the few videos that is at high enough res to actually see the detail of the connector in the crimping tool. After butchering many attempts I watched your video and made the cable I needed :)
Thank you so much for this video! I've searched this subject in the past on YT and all the vids didn't do a great job explaining how to do it properly with good closeup photos of how things should look.
I just wanted a video to show me how to use the bright orange crimper I bought on Amazon yesterday but what I got was an EXCELLENT video strapped to a channel that looks awesome. Easy sub.
Great stuff - a much needed tutorial. What I've found is the second crimp is the important one - if you get the angle wrong (i.e. it isn't in straight) it'll mess it up and bloat out the sides making it impossible to push into the housing correctly. When that happens you can't push it beyond the catch and it will fall back out eventually. You can reshape any bloat by re-crimping at a good angle - but it's messy.
Well spotted I have used a paire of pliers to adjust the crimp after crimping the idea is the crimp should click into the housing and not wedged in otherwise this is an excellent video demonstrating how to crimp.
Daaaaaaaamn! I seriously wish I would have came here a few days ago. I was so confident I knew how these worked and was having a nightmare of a time. Turns out I was wrong about nearly every detail. Had I only come here first I would have saved myself from quite a few super annoying hours of frustration. At least I'll know for next time. Thanks for this video!
A very well-done video. I'm not a trained technician but I work in integration and that means having to bodge solutions together every now and then, simple things like crimping properly aren't really as intuitive as you might think--there are so many things you can do incorrectly. I wish I'd seen this video before I had to butcher a few Dupont connectors before getting it right!
At a guess because a lot of folk, like me, come across videos of specific things but don't need to see everything he does? This was a really great video, but I'm unlikely to watch much else he does
Very nice video Lewis. This is the first one I found how to actually use my crimper tool. For a next time take some more time to show how you actually crimp it because that is why most people click on this video. You showing that was actually very very very quick.... and we want to have a very very good look. So take some time. However thank you so much. I am now ready for my first good crimp :)
You can also , on a 3 + way connector use a male on the outside of a female connector set and a female on the male connector set as a location pin. Suitable when joining 2 connector sets. (I use this for removable/replaceable modules or ease of servicing without having to take everything out and loosing orientation. Great for nema17 steppers).
Such a simple, simple thing, but alas, without your video, I would have destroyed a lot of things trying to figure it out! Thanks for showing high-quality, up-close details for us! This was GLORIOUS!!!
Excellent video, thank you. You covered all of the questions/details I needed to ensure that I was crimping correctly. My cheap crimpers did not come with any directions.
Thank you! Perfect timing for my current project. I watched a few other videos and yours was by far the clearest and easiest to understand. Good job! :)
@@DIYMachines for the first time i have succeeded. Still a bit of a wiggle to.push the metal in the plastic deep enough, but for the first time since i bought a kit i have been able to succesfully crimp a cable. So yes it has been a great help
very well made video. i was looking for connectors to link rgb led strips on acoustic panels and was a bit lost. i initally thought I would use the led strip solder-free connector - but these are awful, and can't really be attached to wire anyway...
Thank you, I find I create these style connectors more and more. With practice I'm becoming very quick and proficient at it and often choose it when prototyping now.
Another use for the male pins is to connect wires to a PCB. Crimp in the normal way, push the pin through a hole in the PCB and solder on the copper side. Trim the pin to remove any excess. Insulate the part on the top of the PCB with a bit of sleeving or leave exposed if you want to use it as a test point. You have a connection which incorporates strain relief and prevents stray bits of wire causing short circuits.
The only thing I would add is to use a pair of pliers to sort of decompress the portion that grips the plastic insulation because mine sort of deforms that portion outside of the parameters of the square hole for the plastic housing. Once decompressed, it should slide into the housing and click effortlessly. If you experience any sort of resistance, 9/10 it's the crimped portion over the insulation.
Yes you're right. Sometimes you need to make a slight adjustment with pliers as you explained. Worth checking if it's not seating inside the plastic housing well.
Nice video, but the crimp shown @2:52 is terrible. The insulation is not gripped properly and the striped portion of the wire is too long. This would interfere with the male connector seating fully. But, in reality, you should never crimp solid core wire. Always use stranded wire instead.
Those things bothered me as well. If you make a tutorial, at least make shure to show how it's done properly. Also, recrimping with a smaller size crimptool is a nono as well.
I have used a cheap ratchetting crimper on amazon once, and have never had any success. The strain relief was always crimped akwardly and would end up too big to fit in the housing. Currently I own an IWISS and an engineer PA crimping tool. Had much more success with those. I personally prefer the engineer ones, since they operate smoother and don't tend to snag. But if you are looking for a low cost pair, IWISS, in my experience, always made good solid crimps that slide right into the housing. I would he curious to hear if any of you here have ratchetting pliers that worked well for Duponts.
Very helpful. But which size jaw opening should I use for the Dupont terminals seen in the video ? Does it depend on the wire size ? If so, where can I find a chart to match them ?
Hi Lewis, tx for the video! Finally a simple and good explanation for diy dupont cables!. But my sn-01bm "pushes" to hard and bends the dupont connector. I think I can loose it up with the vise and 1-6 gear but how? I don't want to break my tool ...
OK, I’m officially stupid! I've just received my kit and I thought I should have had two different styles of plastic sleeve. Thank you, a very useful video.
It's great to have stumbled upon your video and channel! I am very interested to know about the longevity of the crimper you used for crimping Dupont wires. Could you kindly share your experience of how well the tool has held up over the past two years? Your insight would be greatly appreciated.
Thanks. I'm still using the same tool. It may not be a professional version but it does the job for me - however I'm not using more than a few time a week if that.
The production value of the video is excellent. However, the actual crimps shown, especially the female one, are _awful._ Unfortunately, DuPont contacts (with the diagonal offset insulation wings) require a crimping tool with a circular insulation jaw, not the m-shaped jaw in nearly all inexpensive crimp tools. So DuPont contacts are categorically impossible to crimp correctly with 99% of the cheap tools out there, even if they expressly say they’re for DuPont. Also, 5-7mm of insulation is too much to strip. 3.5mm-4mm should be your target strip length for most DuPont contacts. Any less and you can’t inspect it and it could be weak; much more and the wire interferes when mating the female contact onto a pin.
Exactly. The wire should not enter the "tunnel" part. It's OK on the male side, but on the female side the tunnel is where the male connector is supposed to go when connecting to something, that might be difficult with a wire already there.
@@geostrophc Are you familiar with the EEVblog forums? I started a thread there titled something like “affordable crimp tools for DuPont”. Lots of discussion there.
@@geostrophc And also, be sure to check out Matt Millman’s pages on crimp tools. He owns nearly every official DuPont crimp tool (and original tools for tons of other contacts) and compares them, including to cheap Chinese tools. Fantastic resource.
Awesome video!!! How about a refill link for just the cable? Found some, but would rather you get something from Amazon when I get em. If not for this vid, I wouldn't need to buy any, so you should reap the rewards.
at 2:22, strip 5 to 7 mm of insulation off? No! Measure the wings for the bare wire, they are not longer than 3mm. The insulation wings are 2.5mm long. ALSO, don't crimp solid wire! Use stranded wire. BEST WAY: 1) for female connectors, insert a square pin into the connector until it reaches the wings for the bare wire, where it will act as a backstop, 2) for male connectors, close the wings between the male tip and the wings for the bare wire, and have these folded wings act a backstop.
Hi! Thanks for this! Can you tell us the model number listed on the removable jaws inside the crimping tool (for dupont cables). I already have two sn style crimpers. Would love to just buy the jaws.
After fiddling with these connectors and destroying about 20 of them, I watched your video and got it on the second try. Well done!
Glad it helped. That's exactly why I made the video. Information was hard to find on using these and once I figured it out I thought I should share it. :)
I did 4 wrong, gave up & went to bed. I'll try again after work.
