sOMEtimes when i cANt fall asleep I put this video on
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!
LOL, Yes, I do believe that frustration is shared by many!
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.
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.
lol - so true!! I felt the same way, "this can't possibly be so hard! What am I doing wrong!¥@#!"
Part of the reason I made this video, was because if I need to make a specialty cable/length in a few months/years, I'll have documented exactly what worked for me.
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.
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.
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!
This is like watching grass grow, but the best grass grow video yet!! Thank you for sharing this. Great camera work, considering the subject.
Your video saved my ass. I had zero spare connectors and this got me back on the road.
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.
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.
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!
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.
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!!
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..
Thanks for the video , I thought I had the wrong crip tool. I've never crimp anything this small.
Thanks for a thorough tutorial. I haven't done any crimping work, as a first timer this video taught me a lot.
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!
THANK YOU SO MUCH!!!! I was about to give up... I could not work it out, your a saver !! :)
Glad it helped you!
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.
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
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!
You're very welcome! I'm glad it helped!
i watched several videos on how to properly make these connections, yours was the one that did it for me. Thank you!
I was having a terrible time with these connectors until I watched your video. Thank you!! Very helpful!!
deanwesterburg , I'm glad it helped! What are you making? Just curious.
Thanks for making this video. I was putting the pins into the crimper the wrong direction.
Thanks for the very concise tutorial (and props for the macro views of what you're working on that are actually in focus)!
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!
Here I thought using needle nose pliers and soldering the wire was difficult! I guess once you get the knack. Very good video, well explained, clear, excellent closeups. The best of the 4 that I've watched. Tally ho, gotta go practice with my new tool. (Only 6 bad connectors made so far...this video pointed out the error of my ways.)
This video was extremely helpful. I can now crimp almost entirely error free. Thanks!
Extremely helpful. Your camera work is great
Thanks for the helpful video! I admire your patience. I'm not even on camera and it takes me 10x times longer than you and I destroy 5 crimps for every successful one. My family & neighbors know when I'm working. Too bad there's not a larger selection of pre-crimped Dupont harnesses on the market place.
Thankyouverymuch, sir. I've learned a lot, not the least important, i've learned to be at ease, tranquil and calm. Together with Gary Myers 's trick of using some pins ( i use a row of 5, and put the crimped part on the middle) as a guideline made me did the trick! I've had this piece of equipment for half a year, never could use it. Now i started to shorten all of my 3D printer cables to length. I'm happy ! Say hello to your wife :-) Greetings from The Netherlands, Radio-Ron.
Ron Versteeg . heh heh that is so great! I'm glad to have helped so many people because those on internet have helped me too!
I just found your video, and it was extremely helpful. Thank you for putting it up.
Great presentation. I reviewed 4-5 other videos and this is by far the best. Many thanks for your detailed video!!!!
You sir, have just saved me countless hours of frustration. Turns out I go the short pins too! I've been puzzled as to why all my crimps were always crushed. Thanks loads!
NuketardMaximus thanks! I'm glad it helped!
717 dislikes, wtf is wrong with people these days. Great video, thanks for sharing your experience.
Wrong tool for the terminals (unfortunately, the Chinese tool vendors almost universally market this tool model, which is made for much larger terminals, for DuPont), wrong strip length stated, insulation is crimped into the conductor crimp, and the final result is a bad crimp that doesn’t even fit the housing properly, indicating the crimp is nowhere close to what it should be. The video shows some very good tips, but they’d be more meaningful if applied to a proper crimp. What he says is largely correct, but the end result is not an acceptable crimp.
Cool, I should be done with my simple project in about 2 years.
I paid a company to make 600 4 pin -> 4 pin female to female 80mm after spending a weekend making 50. They've got a machine that turns these out like a blur...
I've spent enough time trying this I feel like my better investment is to just buy a damn soldering gun
@@davidhunt240 How much did that cost? Just curious
TheRainHarvester I just bought the same tool from amazon under a different name ($15):
www.amazon.com/gp/aw/d/B07DZBS1FW?psc=1&ref=ppx_pop_mob_b_asin_title
Identical to the tool in the video except different colored handles. 😊
@@TheRainHarvester I vaguely remember it was around $200. A bit expensive, but at least it was done quickly using good connectors and wire. I can get the same thing from China for waaaaay less, but it takes ages and the connectors are often of the type use-once-and-trash and the wire is often CCA and only 32AWG core - ok for signals but won't take any current.
Thanks a lot for this. Very, very helpful and talking is very okay. Takes off the guesswork from what you are doing and why you are doing it!
I created a youtube account just to say that your details (although others may find boring) were very necessary for the correct understanding of the use of this tool. I for one appreciate the details, the close up shots that were clear, and YES we all know how IMPOSSIBLE it is to try to do this while using a camera... Well done..
I also subscribed to show my appreciation.
If you do a soldering video, a tip is get a small spray bottle of rubbing alcohol and spray the contact on the printed board, the alcohol will both clean and evaporate when the contact is heated to the right temperature... this is a good trick for learning. After you get the nack for the time it won't be necessary... anyway I get my tool in a couple of weeks and I'll know how to use them all because you took the time to teach me. Thanks
Flea Fart Thank you. Personally, i thought the details were important even though it made the video longer. I'm glad you appreciated the technical challenges too! Thanks for making a youtube account to leave this comment: I'm floored!! Glad it helped!
Best one. Thanks for showing me.
I think it took me about 5 hrs for 3 Harley Road King Gas Gauge terminals. And removing the 1st 3 because the wires were too far in and wouldn’t allow the harness to snap shut. Next time I only stick in the Tip !
Thank you for this! I was having the same issues and was getting really frustrated, then I watched this and it helped to answer some of those questions that make you question yourself!
you're welcome. what kind of connectors are you using? and where did you get them? i'm wondering if the ebay ones are the common denominator in some of our frustration!
Great video. Well explained as a result my second attempt at crimping was a success.
thanks ..i was having the same problem ..first time user.. this helped so much ...i wasted so many male pieces ..lol..great work ..i think i was using the wrong size wire as well ..speaker stuff .. :)
Thanks for sharing the tool and technique to make a proper connection. You definitely saved from spending my time on learning this.
Ronalds Tilcens, thanks! I'm glad it helped!
Thanks buddy, you just saved what hair I have left! Why could the tool manufacturer not provide something even half as useful as this?
Very helpful video and your camera is clear and sharp. Thanks!
Scooters Denver I really tried to make sure the details were in focus and zoomed-in. I'm glad you liked it!
Excellent, thank you. I know how hard you worked to get things looking good on camera. I now, finally, know how to crimp those fussy little buggers.
Rye Gewalt, I'm glad you were able to find the video useful!
Great guide, works for JST connectors just as well.
What an absolutely fantastic tutorial video.
Just like you i also spent a couple of hrs & i wasted 3 Terminals so far in the process.
After seeing your video AGAIN though i now realise where i am going wrong. I had the terminals upside down in the crimper. It's no joke considering the cost of these terminals is it! If only i could find some already made terminals with about 4" of wire on them so all i had to do was solder them & put some heatshrink over them.
I will now have another go tomorrow.
Cheers Bro
I watch again too because I forget my own tricks and everybody else's tips in the comments!
Thanks man, I managed my first dupont connector thanks to your video :-)
Wish I knew this when I got my tool. distroyed 20 connections however, slightly squeezing the wings in a bit help so much.
Excelent work here - Good focussing, this is a difficult and tricky thing to demonstrate - well done
Thank you my friend, this really helped
Thanks man my crimpers were doing my box in, until I watched this I ordered a complete set from china and as always no directions they think everyone is savy already with them lol, always thanks great help
Thx for making this video. I couldn’t figure out how to use this tool.
VZ_ 342 same here. At least he gave an idea of how to use it.
Allah razı olsun sizdən çox gözəl video idi. Teşekkür edirəm.
Thank you. I found this very informative and helpful - saved me a lot of time and potential problems with my project today. I was hoping that buying a proper crimp tool rather than using fine nose pliers would be easy .... not so! The only issue which you didn't mention was that of the crimped wire "sticking" to the tool once the ratchet has been released - a very delicate operation to release it without bending it and breaking it off but hey ho - I will continue to investigate. Thanks again.
Thanks for the detail. Awesome video.
I agree with many others. This is the best of these demos that I have seen on TH-cam. Well done and thank you.
Tracy Wallace, thanks! So many people making things! How did we ever learn without the internet?!
This was excellent. Thanks for the camera detail.
Great demonstration! Thanks!
This is the best video in the topic! Thank you man, you've made my day!
Thanks for posting. Some good info in there.
Thank you for the great video.
Use a two pin male header to make a crimp holder. Cut the pins to length so that one of them pushes into the housing to the right depth to keep the wire from pushing too far forward. The other pin sets the distance to the crimper so that the crimp is held at the right position. Solder a short length of brass tubing to the opposite pins to act as a handle.
I'll leave the method of making female versions as an exercise for your imagination.
Gary Myers That is an excellent idea! I'm definitely going to try it! Thanks!!
you should let people know where to get this brass tubing since it seems some are not clued in enough to even get what the video implies or have the patience to watch it. I am guessing K&S metals like found at hobby and ace hardware stores usually used for model railroading.
I tried your idea with a 3-pin male header, its center pin inserted -- at 90 degrees to the jaw opening -- into the connector on the side opposite the wings for the insulation. The outer 2 pins of the header touch the sides of the upper and lower jaw. The black plastic that holds the 3 pins lets the center pin be longer, letting its insertion set the limit for how far the wire and insulation can go into the connector from the winged end. This works great for female connectors but not at all for male connectors. I think yours is similar. Anyways, thanks for the suggestion.
I'm using a different pin style but your video was very helpful with the issues of getting the pin and wires just right. Thank You.
Just got end connectors and pins (Furukawa style) for a Yamaha outboard and NMEA connections. Company is Corsa Technic in Wisconsin. I live in Oregon and their prices were very good and shipping only 4 dollars. Corsa-technic.com. Also just ordered harder to find male ends of same make from small company in Japan! He builds wires sets for special small scooters and bikes and had the connectors and pins. Good prices and shipping was only 6 bucks.
Cycle Terminal is another site I found but didn't get anything, same things carried though. Eastern Beaver is the Japanese company I bought from. They all had a bunch of types of connectors and pins, don't know if it would apply to computer boards which I think I heard you mention. Good luck, let me know if I can help with anything else. bill
i love your crimping videos :)
I thought for sure that I bought the wrong tool I'm not using this type of connector I'm using JST-XH Kit 2p 3p 4p 5Pin 2.54mm Terminal Housing PCB Header Wire Connectors. When trying to crimp it would also crimp the locking mechanism on the pins making a poor connector, if it gets any type of a tug it will come out of the connector. I watched this and well I finally made 1 solid connector once I inserted the wire I pushed it until the lock on the pin came out of the tool then I crimped it and presto it worked not sure how many pins I've wasted in the last hour but thanks for making this video it helped me see what I needed to do even though we're using different pins there was enough information for me to figure it out, now I need to buy more connectors.
🤷♂️😁👍 I wonder what other things this tool can crimp.
Thank you so much for this video! I was about to throw on the wall the crimper! but it finally works!!! Thanks!!
toff christophe , yep! I knew the feeling!
For this type of small/delicate projects it's good to 1st have a pair of those "mini precision wire cutter" for reason below.
2nd, there is no right or wrong way here just what is convenient (your method to pre-cut the copper wire to length or leave the copper wire long), insert/lay the wire and align the wire insulation to the correct space in the female/male metal connector then wrap the extra copper wire around the mid section of the metal connector, now hold the wire and gently place the connector in the correct orientation in the crimper slot/jaw and crimp.
3rd , removed the crimped wire & connector from the crimper, use that mini precision wire cutter to cut away the extra copper wire. DONE!
This way, to me, I align the wire in the metal connector exactly where it needs to be before place them in the crimper, also there is the whole wire to hold-on to without worrying the wire slips out while crimping.
Rick T , that's a good idea! I'm going to try it. I would have thought the extra wire would get tangled in the connector, and that it would be hard to trim to length afterward, so I never even considered this!
Thank you for the tips, that thumbnail trick just saved me so much time.
It's the little things, isn't it? Glad it helped you.
Ok so, from learning about building my own computers, here' s what I found. When you plugged the 2 wires into the black housing, you put them in backwards. On the black housing, there's an arrow. That arrow should have the positive wire. You had the negative wire in it. It's just a way so that you can identify your positive post if you were to decide to shrink wrap the wires, you'll know what the positive post is. Great video though. I just bought this tool and had no clue how to use it...Thanks....
Neat, I've never noticed that before! Thank you for that knowledge!
The arrow indicates pin 1. There are no standards as to what pinout is used. On my own designs, I tend to assign ground to pin 1.
It has a lot to do with having the correct die and correct ratchet setting on the crimp tool. You have to dial the ratchet setting in first. This prevents you from crushing and distorting the pin. Next get the length of the strip right. After that preset the pin, meaning squeeze the pin tray so it holds the wire firm. That way you can see that everything fits. load the tool and squeeze at the end of the handle to get the most leverage. You have to do this with every pin manufacture because not all pins are alike.
The ratchet provides a consistent crimp.
Lovely detailed explanation! I've watched a lot of these videos, and yours was clearly the best. A lot of the time "pros" don't cover thing that are super obvious things to them...:) I personally am only looking to make a couple connectors, so I don't really care to buy some $50 tool!
Oh you're welcome! I'm glad it was useful to you.
TheSN-28B tool costs $4.25 on AliExpress.
This tutorial is very very very helpfull. Thank you very much.
Thanks for this! I was having some serious trouble but your video had the tricks I was missing. One was pre-squeezing the insulator "wings" so they fit fully down into the tool's smaller gauge crimp slots, and won't twist and turn as you crimp; and most importantly sliding those same wings until they stop at the ridge, to find the perfect connector insertion depth. Also middle agers out there beware, once you hit about 46-47, to do this kind of stuff with tiny components you need reading glasses and a whole lot of light. It is not gradual, it happens rather suddenly.
I have bad eyesight as well! I'm glad it helped!
Great tutorial, man! I've been having trouble making good connections and you've clearly taught me what I'm doing wrong. I've been pushing the wire in too far, believing the part that's supposed to grip the conductor was the insulation clamp.
Good tutorial here, thanks for showing us. Lots of little clues to get it right.
Gort Newton you're right about the clues! I was clueless, and had to remember every trick... that's actually why I made the video: to remember for myself too! :-)
hahaha, love it, I use a similar method when exploring a new tool in my workshop, I write down a text file on it, but you do it even better with a video. Well done lad! On the basis of your video I ordered an SB-28B crimp tool. Thank you.
Thanks for showing this. I also bought this crimping tool and i thought it would be clear how to use it or maybe there would be an explanation on the packaging. I was begining to think i had the wrong tool for these dupont pins.
I’ve always had trouble with crimping and it’s all because I thought my crimping moulds were badly made.... SO I FILED THE RIDGES AWAY LOL.
So now I’ve got a new set of crimps and they works great... still need to get some practice I’m doing JST sockets and they are TINY in my big meat hooks.
So yeah, thanks. (Still can’t believe I screwed up by cleaning up those heads). 😳
Neo Morph , lol that's great news! (Except for filling the old ones.) I'm glad you got them working!
TheRainHarvester they do look like they have been badly cast though... I used to use the old style of crimpers years ago where you crimp the conductor first then push it forward and crimp the insulation. But my grip sucks now so I thought a ratcheting one would help. Oops!
Neo Morph , what are you making the cables for? Just curious. I use these cables for custom lengths when I need a few on some Arduino projects.
Great video , still can't do it properly but learning , and wow your voice sounded like dirty harry doing video lol ,thanks again for showing tips on how to crimp
Thanks you save my life
Excellent tips! Thanks
That's the most stressful, most cumbersome lookin, overcomplicated crimping tutorial iv ever watched.. good amount of info tho, thanks for taking the time to show us
Stephen Nganga It could be shortened a bit. But I didn't know what parts to leave out/assume others already knew. TH-cam needs a way to dynamically display a " jump to" button, to jump to the next interesting aspect of the video...
ㅍ
Super super thanku sir very good explain
Thanks to your excellent video I did my first two wire connector using only 6 pins. As for the length of your video, it gave me an excellent feel for what the process feels like. If you had condensed it into 30 seconds, it would not have been as useful.
Wow thank you so much you are the mega man you saved me so much time and headache god bless you my man you made my first crimping project a successful one thanks again
+jjella77 I'm glad it helped. Thank you!
Good video. Very helpful. I usually use a different crimper to do stereos installation and such but now I’ve moved on to messing with car ECUs pinouts and at least trying to make it look professional rather than Mickey Mousing shet for quick fixes.
You will find these easer to use if you swap the jaws over so that the forming jaws are on the top, it much easier to use that way.
That's a good idea. I wonder why is was upside down.
What a good video! You saved me hours of headache!
growingfuzzybeards that's great! I'm glad it helped.
very good several thing I learned.
good video helped me a lot
I use a tool sold by Mercury Marine and it works perfectly with no effort. It is thinner and has no ratchet, nor does it need one.
this helped me so much! thanks!
philip james , you're welcome! I'm glad it helped!
Curling in the "wings" was a mystery to me before this vid ... thank you! Strange my tool did not come with instructions. Certainly needs some! Gosh, I have ruined about 150 connectors.
I'm glad it helped you. I felt your frustration!!
With the short pins, they should press about 3mm further forward into the housing. The ridge you hook your nail onto to position them is where the latch on the cover is supposed to grab.
how come the information about many tools are an investigation effort out of the normal? If I produced some tool, I would make helping info easy accessable.It increases the tools value.
One important thing your crimper jaws are upside down flip them and and try again ,the flat should be pointing down and the curved up so when you insert the wire you can see how far you are in
94Discovery , that's a great idea! I was wondering why I had to hold the tool upside down!
Thanks for this one
Brilliant video, sadly I eventually gave it up as a bad job. I need better eye sight or something.
