Custom Cables & Guide to Crimping Dupont PCB Interconnect Cables
Вставка
- Опубліковано 14 жов 2024
- This is a very quick video guide to working with custom PCB connectors. I recently had to make a custom connector for my Raspberry PI, which has a bank of male headers. I looked at a few different options and in the end I decided I would invest in a crimp tool to create my own custom cables. While the experiences are still fresh in my mind I decided I would make this video in case that it will be of benefit as an introductory guide to others who are trying to do the same sort of thing. The video will discuss regular ribbon cables, fixed length pre-crimped cables, and custom crimped cables. I will also give a guide to how to crimp 0.1" male and female PCB interconnect cables and describe what a proper crimp connector should look like. See: www.derekmolloy.ie
About 15 minutes ago I was looking at "some" connector and trying to figure out how to attach wires to it. Now after watching this video I know what type of connector it is and how to connect to it. Excellent video !
A great video for someone who never quite understood those little buggers. Thank you.
That is the most thorough, well presented and informative instructional video that I've ever watched on UA-cam.
Brilliant, thanks.
Rick White - I absolutely agree. Excellent job. Thanks.
Rick White - I absolutely agree. Excellent job. Thanks.
I agree. What a level of presentation.
only video I have been able to find that shows the proper crimping of these connectors, good job! All other videos show improper wire stripping length and crimping only bare wire.
Friend - this is the most comprehensive instructive video on cables and especially crimping. Very nicely done. I'm subscribing.
Very useful - thanks. One thing I do differently that I find works well is not to detach the metal connectors from the strip until after the crimp is complete. This makes it much easier to hold the connector in the perfect position in the crimp tool. They are also easier to snap off the strip once the wire is attached.
You have the perfect combination of cadence and clarity and a pleasant tone..fantastic!!!
Very good tutorial! Custom cables offer an advantage over ribbons for Eurorack synth module power cables: ribbons are typically 28 AWG and the parasitic resistance in them causes noise problems in many Eurorack systems. Ribbon cables are good for data--not for power, particularly in sensitive analog systems! Using crimp pins allows module power connections to be made with 22 AWG wires (53 mOhm/m vs 213 mOhm/m). In addition, custom cables can be connected to bus bars in a star configuration, rather than using a distribution board; that eliminates coupling of voltage drops from one module to another.
Rarely do I stop to comment on UA-cam, but wow... what a video. I had ordered like 1/3 of the items I thought I needed and thanks to your video I was able to actually find the pieces required and as a bonus learned how to assemble some very useful cable.
Wish I'd seen this video BEFORE I started crimping. After four days search online and as many days wandering among suggested retailers to locate what I 'thought' I needed (which was the mailing time to get it for a fraction of the cost from Polulu),I wound up buying an acceptable set of connectors and pins for my project. HOWEVER, with the totally worthless tools I purchased, I wound up working on my back for several hours to get the 8 pins crimped and bloodied my thumb badly attempting to hold the pins in that lousy tool. OUCH.
So my moral is to keep searching until you find this video...>) and if you've completed your project, now you are the wiser.
GREAT explanations and WONDERFUL video quality.
Thanks again Derek for another very complete, clear, yet concise video. You are quite a communicator and your accent is wonderful! I think I shall be getting myself a decent crimp tool now!
You and terrysb20124 are two of the best out of the dozens I have had to endure, Thanks Derek.
Excellent video. Clear and simple. I have been making up servo connectors for model aircraft and could never figure out how to get the tool and crimp aligned. Thanks for your great help. The connectors look very like rc servo connectors for model aircraft. A crimp tool which works well is available from Hobbyking for €12. Cable and connectors can also be found cheaply and also cables made up mostly for 3 pin servo connectors in various lengths.
Very simple video. Just what’s needed. I like to close up the crimp with needle nose pliers before the crimp, easier than trying to hold the wire, crimp and crimp tool as I only have two hands. The other advantage of making your own ribbons is that you can maintain colour integrity. All I need now is a way of holding then in a ribbon shape.
I use a set of "helping hands" to hold both the wire and the crimp connector pin and then crimp it with one just hand. This video demonstrates some good techniques.
Thank you very much for taking the trouble to share that with us. For me it was extremely informative and useful.
Congratulations on the excellence of the production in every respect: clarity, simplicity, thorough and methodical approach and presentation, excellent photography, and a delivery and presentation that the BBC would be happy with. I have liked and subscribed.
Every guide video should be of this quality. Thanks a lot.
SHOULD BE?
Easy to say. It's a LOT of work, and usually - in exchange for bugger all.
Excellent, clear & concise explanation. Camera work and stills the best I've seen, commentary precise and relevant. This process is something I'm about to use for wiring some infra red sensors on a model rail layout, so thank you very much, and I've subscribed on the basis that there is bound to be more of this stuff I can learn about.
I had no luck with crimping until I found this link from Pololu. Very helpful, Derek, and much appreciated.
Thanks Derek! Just what I have been looking for. There are so many types of connectors out there that one can get lost! Thank you again!
I work in a wiremill and I have to use those dupoint connectors terminals and a proper applicator. Just letting you know you should keep an eye on your crimp depth as if it's too high it will crush your wire, and if it's too low, it won't be a snug and will come off over time...and the scary thing is...you can't tell visually if it's too high or low. You should use a depth gauge and a pull tester to get the proper depths depending on your wire gauge.
also the way the insulation crimp went in your demonstration would have to be rejected because there is a chance it could have cut into the strands.
just letting you know.
I wish I can give you TWO thumbs up! I've now watched this video 2 times. Great video! It was clear and concise. It completely took a way the mystery of custom cables. Many thanks!
Been looking for this exact video for the longest time. Custom connectors are definitely the way to go. Thanks mate!!
This was a good guide. I have a very cheap crimper, thin wires, and low quality components and it’s an absolute nightmare to get a good crimp. I end up soldering the pins to the wire and using the crimping tool to close it up so it fits in the plastic sleeve. Not an ideal solution by any means, but it’s what seems to work for now. Eventually I’ll experiment with thicker/higher quality wire, components and then a tool, but for now the absolute cheapest stuff works if you put a little more time into it haha
This is the best instructional video I have ever seen, ever.
Extremely well done! Thank you. This was very informative and expertly laid out. It covered the exact questions I was having while investigating what's needed to start diving down the microcontroller rabbit-hole, such as Arduino, PIC, and ESP8266. I will recommend and share this video with some friends who are also thinking of getting into some hobby projects. Cheers!
very helpful. adding the crimp is definitely a challenge - I needed to hold the wire in a vice and use an eye loop. thank you1
Great tutorial and exactly what I was hoping to find. I was a bit sad when it ended as your dialect is completely soothing.
Excellent instruction, i was disappointed with my crimping tool until i saw this. Clear and crisp video that helps explain exact positioning and use of the tool. Thank you :-)
Thanks Derek. You video made it clear how to use this system and I've decided to invest in the tools for a large project.
Thank you for doing this video! It's very difficult to find any good cables out there for PCB connectors. I appreciate your time and effort making this.
Thanks so much for sharing this. Really talented use of closeups and explanations of what we are looking at. This is 5 star rating stuff.
Really great video! I would just add that when crimping it is much easier to strip just 1-2 mm, click crimper partially closed only 2 or 3 clicks depending on brand, then you can just drop the empty crimp pin into the tool and it will catch it at the correct depth, click one more time to grab the crimp pin. Now push wire into tool and crimp pin. Assuming the wire is stripped to the correct length, then the teeth that crimp the exposed conductor will block the insulation and stop the wire at the perfect depth. If you're using very small guage wire, such as 24 guage found in cat5e cable, then give the tool an extra click or 2 before inserting wire.
wow you hit the subject spot on I converted several dozen arcade games over the years and have dealt with molex amp and countless other strange Japanese and European DIN standard pins connectors tools and various other forms of electronic joinery and I still feel like I learn something from watching your video ...cheers from San Diego
I just bought your RPi book and this video is my introduction to you. Great video! I can’t wait to dig in to this book now!!
Great instruction video sir. Clear instruction and sound. Quality recording. Hats off. And thank you.
Thanks for this excellent video, just what I needed to know. Fellow cheapskates might like to know that very cheap connectors of this type are available direct from China on Ebay. The keywords to include in your searches are "dupont connector".
***** Long wait times that means there is no agency in your country ,if it does, anything would be much faster than any country in the world.
What a brilliant demonstration. Thank you
Thanks for sharing your useful experience via this video! I suspect you've saved me time and money that can be better spent on the embedded computing and electronics projects I've got in mind.
Best description of this process I have found.
From personal experience I found it easier/necessary (30AWG) to cut the ribbon the pins are on providing a tab to hold while crimping then breaking the tab off the pin post crimp. Hope this helps with smaller gauges and larger thumbs.
This is what I just wanted to mention. Thumbed up your comment :]
This is how UA-cam how-to videos should be. Thank you very much!
Thanks for the video, it was very useful, I spent at least 1 hour trying to find this same information in various forums; your video is very clear and I have bookmarked it for future reference. Thanks again!
The proper crimper for those DuPont type terminals (they are known as Mini PV for the Dupont/Berg/FCI Amphenol version or M20 for the Harwin version) is the FCI Amphenol HT-0095, HT-100, HT-208, or HT-213 for the FCI Amphenol version or Z20-320 for the Harwin version (the terminals will work with either). Double D crimpers don't work as well for these, the official factory tool has a cylindrical die and swages the barrel into a tight tube around the conductor. Old Berg and DuPont branded tools show up on ebay regularly for under $100.
Great informative video. I was referred to this video by Derek Molloy's "Exploring Raspberry Pi: Interfacing to the real world with embedded Linux" book (Chapter 4) which has a boat load of valuable information about the Raspberry Pi and its electronic and software interfacing design and development.
Awesome Video, I have bought some female jumper wires from yourduino
They are very cheap at a reasonable quality!
They are already pre-crimped you would how ever have to take of the black housing at at least one side.
But they only cost 2.00 Dollas for 40 cables (20cm) or 2.50 Dollas for 25cm!
Great presentation. You should tell all the connector companies to include a link to your video.
Derek,
Thank you for making this education/training video available.
The Arduino boards I am using have the same pin size and spacing as your Raspberry Pi in the video.
I searched Google for the crimping tool with "SN-28B Pin Crimping Tool 2.54mm".
Mine has just arrived from ebay for $US11.80 + $US3.00 postage, seller accecity2009.
Now I can make projects that look a lot more professional.
Regards,
Colin
Thank you for your video! It helped me to make my own custom cables for my recent build. Very well done.
Excellent and very instructive. I get my supplies from E-Bay. Super cheap and comes from China, but seems to work very well. I've also seen these types of connectors used by model airplane hobbyists for servos and RC modules.
Very well illustrated. Thank you.
Really helpful! I was looking for information on how to use this type of connector and you answered all my questions.
Fantastic!! Thanks for taking the time and posting this video!
Great video. Thanks for the detailed look.
One brilliant tutorial on crimping. Well done and thank you.
it cant be done better ! excellent video. greetings from germany
Perfect. Thanks for the clear, detailed explaination
please note: I don't have giant thumbs - I'm just giving this video a big thumbs up
I've always wonder about creating my own custom connectors. Excellent Video. Thank you!
Wow - that was perfect for what I wanted to know. i can proceed with some confidence now. Thanks.
Great tutorial. Stuff like this is really useful. Those pesky little details seem to always get in the way :)
Derek - KUDOS on one of the best tutorial videos on You Tube! It must be good - I've been back a second time... :-)
very professionally done and correct all the way. Thanks!
Hi, thank you very much for the video it is very helpful.
Where can I get those kind of connectors, dupont connectors?
Excellent presentation.. and great voice.. very useful.. thanks..
perfect! thank you for posting this video I'm not sure why this kind of information seems so difficult to find. cheers!
Thanks:) Alternate sources are our local RC hobby shop (it was cheaper at my hobby shop but I had already ordered from pololu. Also bangood.
Nice video. Have you come across a cheaper source for the 6 inch pre-crimped cables and connectors?
Still useful in 2021! Thanks!
Thanks a bunch Derek, you completely demystified it for me.
very intresting vid. Thanks.
I found the same crimping tool on ebay for 15$.
Also i buy some pins on ebay too, but they dont fit in the dupont housing.
I advice to double check the pin dimensions before buying. ;)
You did an EXCELLENT job !
thumbs up for the web link. i always wondered how they make these tiny connectors.
This was super helpful, thank you!
Excellent video. Thank you!
Great video, thanks for taking the time to share your experience!
Very well explained and commented video! Thank you very much! Karl
Outstanding video, clear and informative, thank you so much!
Thank you for this great explanation of this option. I'd like to find those teeth to fit in my current crimp tool that I have for RJ-45 and RJ-11. Any idea what I'd search for to find the proper part?
Fantastic vid - Thanks for your effort
Thank you so much for sharing your expertise. Helped me a lot.
Very useful and very well made video, thank you!
Aliexpress has the hole crimp kit at a fair price.
And yes their fun to use.
Ultra precise and thoroughly explained, thank you so much, God bless you.
Thank you. I had some issues as I used 24 and 28 AWG cables. I've sourced my tools, parts and cables from ebay (chinese vendors). Crimp tool is around $10 there incl shipping.
Great video! I've been using these connectors (with same tool) for a while. But since I switched to so called polarized connections. They are much more secure at connecting (also .1 in pitch), and actually very chip from Taydaelectronics (they call them wafer connectors). Alas I yet to find a crimping tool for polarized/wafer connectors...
Fantastic presentation. Thanks you so much!
Good and clear video.
Very nice instructions. Thanks for your time making the video and sharing it with everyone in the world. :-)
Great video. Have you considered the Engineer PA-09?
Very useful video , thanks.
Superbly done and exceptionally informative. Simply perfect. Thank you, Derek! Now, where's that "Subscribe" button?
I separate the pins by cutting the foil strip between the pin and then use the foil portion to hold the pin in place while crimping. When I show that trick to people they feel foolish that they didn't think of it.
Awesome video, it helped a ton! Thank you for the assist!
Excelent video! it has all what I needed to know. Kudos!
I bought 22AWG stranded cable as suggested here but it was too big for the metal Dupont connectors (the end part of the connector that crimps the plastic sheath needs bending out, very fiddly), also the cable was too wide to fit into the plastic Dupont housing! Does 22AWG refer to the metal strands, or the outer sheathing? I'm guessing the former, in which case watch out because it appears the sheaths are not necessarily going to fit if you buy the right cable!
I measured the outer diameter of the 22AWG stranded cable to be 1.6mm, whereas pre-made stuff is 1.3mm. There's the problem!
I can make it work, but it takes about 4 mins per cable: not efficient!
Really useful and clear - thanks!
Exactly what I needed. Thanks!
Exactly what I needed. Thank you.
Thank you for this video!
