Thanks for the video. Just got one of these and it came without instructions. After destroying a couple connectors, I found this video. You're a lifesaver!
These are my favorite kind of videos; unpolished, hobbiest to hobbiest, "Here's something I learned" kind of videos. Thanks for making it.
Thanks! I appreciate the kind feedback.
This was such a helpful video, you've certainly spared me agony and saved me time. I don't think it's "unpolished"; I think a better choice of words might be "not over-produced."
I wouldn't mind a *bit* more polish, say a tripod and arm (as in the soldering aid devices) to keep things steadier. But it's still one of the best videos of its kind I've seen. So many others gloss over or skip the really important bits, taking some thing for granted. I really appreciate the macro shots and thorough explanation. Thank you for that.
Exactly, no music, no nasty intro or flare.. just the raw information explained in easy to follow steps!
Yes one of the best videos on the problems of crimping. After wasting hours and dozens of crimps I am noe getting it correct.
1 He shows the correct way to insert the crimp. Its counter intuitive i.e. upside down.
2 He shows the correct way to inset the crimp with the "ledges" in the tool clearly shown.
I have just bought a crimp tool like the one used but the jaws are different.
There are 4 slots not 3
The jaws are only 4.7mm wide. This means that when the "wing" for the insulations is perfectly positioned in the wider section the "wing" for the copper is slightly too far out and is not caught by the crimper.
Best video on this topic! Even with the blurry parts.
Since my last comment, I've crimped 30+ connectors and they have all been perfect. So just wanted to say thanks again for this.
Thank you for the Video... I successfully managed to kill about 6 connectors before I stopped and stumbled on your video. After watching Success. I had the wrong orientation of the Dupont connector. Everything you could do wrong... I had tried. Your video put me on the path to redemption. Awesome Job and Thank you.
This is seriously the only video that explains this properly. Think of all the wasted pins they could have been saved.... Thanks for posting.
Oh my god. Thank you. I was seconds away from throwing out my crimper and just fucking soldering everything. I followed your instruction and got a perfect crimp
Thank you. First and only video I needed to learn how to use my new crimp tool properly.
Excellent explanation. So many videos just blindly (to the viewer) place part in the tool with no idea which way up and which way in and so on. Your attention to detail helps your audience not having to keep looking through 100 videos to finally getting to yours. Thanks!
Just wanted to say thank you for this video! You're the only person I've seen go into detail about getting the proper orientation and explain the two different sizes required for the wing part that crimps around the wire insulation and the barrel part that crimps around the bare wire(s). FYI, I have the Qibaok Qi-28BMA crimper that has 2 channels - the smaller one for Dupont connectors and the slightly larger one for JST/XH/C3-R connectors. With my tool, you have to insert the connector as you described - with the V of the wings opposite of the V of the crimper channel, ratchet down once, which holds the connector in place, then insert the wire and continue ratcheting until the crimp is made. You're also exactly right that the orientation of the connector is counterintuitive. Again, thanks!
thank you so much. You saved me hours of trial and errors :-)
Thank you so much!! I was crushing every single connector. Precisely! As you point out, the placement on the crimper makes all the difference. Cheers!
Thank you Terry! I have watched alot of UA-cam videos and yours is by far the best at showing how to do this job accurately. It will save me much trial and error. Thank you for what you do.
Undoubtedly the best video on this topic. I just counted and I had wasted 11 connectors before I decided to put it all back in the drawer and try again later. After watching this, the next attempt was successful and, even better, the connector fit in the plastic housing perfectly. Many Thanks!
THANK YOU! This is the first video I've found that actually helped me successfully crimp my own cable! Seeing close-up exactly how to position the connector in the tool was exactly what I needed to see.
I watched a ton of videos trying to figure out these connectors, yours is the one that made sense.. Thanks. Extremely in depth on the entire connector and very useful.
UA-cam is great...thanks to you Terry. Thanks!
Excellent tutorial. Thank you. The macro lens closeups were very useful. So many crimping tutorials I watched before were so poorly focused, I couldn't see the key features. I finally understand this now.
Thanks to you and others who have commented here. I'm glad this video is helping even if some of the shots are shaky and the subject matter is a bit tedious to present :) I hope to resume making videos soon. I built a new workshop in the basement and also a proper video/photo studio. So, hopefully I'll have more room to shoot the video content and can improve the quality. I've accumulated a bunch of "kits" from ebay so I plan to put some short videos together on how to assemble this stuff and get it working.
this is by far thee best explanation of this process I have found.I need to learn this for automotive wire.Thanks Terry You are very knowledgable I will watch this video several more times.Gladly subscribed .Thank you
I've watched several videos and i must admit, this vid was like the best one. Thank you very much for being as accurate as possible!
After a few lame attempts at crimping, I decided to look to UA-cam for assistance. The first video I found was a useless crimping video that featured how soldering the wire is the trick. Wrong. Luckily this was the second video I found. You provided absolutely the exact information I was seeking. Much appreciated.
I like this video because you got in nice and close. Despite the shaking I was able to absorb what had to be done, and you saved me a lot of time! I found that my crimped connectors were not fitting into the case, because I was over-crimping. The tool has the adjustment wheel for the tightness of the crimp and now this adjustment is right I am crimping quickly and consistently. I am grateful you took the time to explain.
Great video! Received my crimper and connector kit today. Definitely not intuitive as to how to crimp, and this was perfect. Worked out even better that I have the exact same crimping tool. Managed to get a correct crimp on the very first try.
Terry, thank you. Many videos have this wrong. I just did about 15 crimps on a model railroad control module incorrectly, found your video. Bam, now all is well!!!
Excellent video. I was just about to junk the entire kit of the crimping tool, the dupont connector assortment and the male/female pins all into recycling after frustration, but then I ran into this video. For me the key was how to understand the mechanics of this crimping tool which is well explained in this video, shot with macro lens.
I am so damn happy I found this video. I had to replace the RCA cable going to the reverb tank on my amplifier and of course it's 4 pin connector on end. It took me two and half hours to make a four pin connector. I would never have figured it out if I didn't find this video. Thank you!
Thanks a ton for this video! I got a setup to do this on my own but when I got it I had zero clue how to use it and there was zero instructions on how to do it. Likewise I wasted 3 before seeking help. One thing I did do different is I saw on my crimpers at least I could undo a screw and was able to reverse the crimp flanges. So I moved the bottom to the top and likewise for the other one. That way I can hold the crimper the logical more comfortable way and it was perfect. Made all my connections and on to the next step, again thanks so much for taking the time to make this slick tutorial!
On a side note for those like me that are using the tiny 1550 connectors its not a bad idea after crimping them to hit the wire part with a dab of solder to ensure it does not come out. I am finding these crimpers are just to big for these very small connectors and not doing a very solid job wrapping the tongue around the insulator.
I wasted alot of time watching other videos, but this is the absolute best tutorial I have found. Great job, great information. Thanks.
Thanks Al!
thank you for this video! and i agree You're the only person I've seen go into detail about getting the proper orientation of the crimp conector
thank you, ive had these an entire year and watched what must have been every single other video on the subject and despite youres being here four years I never found it until now. Im sure you know by now but the other die jaws are for spades and other connectors according to the size of the crimp etc. Also I noticed the foil filament that connects the uncrimped connectors in the package is useful to fit the connector in the slot properly by giving a backing wall to back off and line up the connector into the ridge line of the die jaw. Again thank you!
Thanks - I burned through 20+ getting it wrong using other instructions I found. This one worked just about perfectly on the first try.
Best video I've seen explaining how to use the tool and crimp wires. Thanks!
Thank you so much for making this video! As others have said, your video saved me many wasted hours of stress. I finally understand how to crimp duponts correctly and consistently!!!!
Thanks also for taking the time to make this video. I also had watched a bunch of videos showing how "simple" it was while I wasted connector after connector never able to get enough of a reliable result.
I love it. This is the only youtube video that helped me AT ALL in this endeavor. I'm grateful to you for having made it. Nonetheless, I feel I must offer these points of constructive criticism. First, the out-of-focus macro shots.. I understand the difficulty in pulling those shots off, and they WERE somewhat useful, but I can't help thinking that an illustration might have done the job, along with an in-depth narrative such as you delivered. And also, I'm glad you said definitive and not exhaustive, because you left out the whole part where one seats the crimped hardware into the plastic. Which isn't completely straightforward, it turns out. How to orient it so that it clicks into place the way that it's supposed to, especially when one is not attaching a wire at all, but just making a connection block, ie. female connectors in the plastic with no wire. I'm constantly re-configuring and re-using the same arduino uno for use as an ISP, and the connections I make are temporary. Anyway, I'll figure it out one of these days.
my crimper now works perfectly. thanks
Thanks for taking the time to make this video. After watching your video I had success my very first time. I was kinda nervous about what I was getting my self into after reading a lot of the reviews for different brands of tools. I actually found out about your video from a crimper tool review on amazon.
Thanks Terry. I looked at a tutorial and 2 other videos ans made 10 bad crimps. I watched your video and actually understood how the damn tool works! The first crimp I made was pretty good. Thanks again
Thank you for your great video. I watched 3 other useless vids, your close up views are what helped make the explanation very clear.I would think you could either practice holding the crimped the right way and get used to having your connectors "upside down" or you might be able to switch the jaw inserts. I have a crimper on order, I think your video will be very helpful. Big live crimps a lot and he is really good. He explains it well, but your close up shots make the process make sense. Thank you again.
Thank you! Even though it was shaky, it was the best, most precise video on this that I could find.
What I've been doing on the past couple projects that required crimping dupont connectors:
1) Strip the wire end
2) Line the wire up precisely in the crimp
3) I crimp the wings over the conductor with a PA-09 engineer crimper relatively lightly
4) I finish the crimp by crimping both the wings over the conductor and the wings over the insulation with an SN-28B
The reason I do this is because I found that if I put a crimp inside an SN-28B, I cannot see exactly how the end of my wire is lined up inside the crimp. The PA-09 is much thinner, and I can see where the insulation ends and where the conductor starts between the 2 sets of wings in the crimp right before I start my crimp. Once I crimp the wings over the conductor portion in the PA-09, the crimp will not move on me. Then I crimp it down fully with the SN-28B, which creates a good quality crimp on both sets of wings.
For me, the most frustrating and challenging part is to get female crimps into the plastic shell housing. I think I may need to strip the wire more cleanly sometimes to avoid any bulges where the insulation ends. I think I should probably also practice sometimes squeezing the wings over the insulation down a bit more with pliers if it's hard to slide female crimps into the connector housing.
You are excellent and very well explained. Thank you
Anyone who criticizes this video is a fool. Yes maybe its a bit too long, but I'd rather have too much than not enough. This made me a pro after my 2nd attempt. I've looked at other video's, but this one was perfect. Even though at times the Micro Video quality was pretty bad, it was needed for the critical point about how to properly insert the Dupont piece. Thanks so much for taking the time to do this. Gottal love UA-cam for ideas on how to figure out how to do just about anything.....
Thanks very much for your comments. I'm glad the instructions worked for you. When making this I knew I wasn't going to win the Oscar for best cinematography and that trying to explain all the details behind crimping these connectors was going to be a real sleeper. However, I'm really happy to see that it has succeeded with the original goal of providing enough detailed instructions so that someone could crimp these connectors with consistent success. It was really frustrating for me to watch the other videos out there and still not have a real clue as to how to make these things work. I went through a couple of dozen connectors before I got frustrated enough to take a few steps back and figure out steps that would yield reproducible results. Thanks again.
I went through 6 connectors. After coming across this video I ruined 1 more and then got 4 in a row. Kudos, solid explanation
Relally helpful. Tried a few and gave up. Glad you made this. The shake was no worry, you had enough there to make the point clearly. Especially how to work the tool.
thanks so much for this video i have some crimpers on the way and this video clears up alot of questions for me! very confident i can do this right, now i wont have worry if my connections will fail!!
Oh yeah, working everytime. I'll be referring everyone to this video who needs help crimping. Awesome, just awesome
This video was very helpful, thanks so much.
Thanks man, you saved me from throwing away my crimping tool :) Great explanation and 100% success rate!
Wow, thank you for this video, I wish there were a lot more tutorials like this one!
First video that explains it all. Thanks. I had the connector the wrong way around half of the time.
Thank you. Exactly what I needed to know.
Finally!!! A video that showed me the right way to crimp these lil bastards! I've watched 4 other videos that all said to do it the opposite way that you do. Tried your way and boom first try! Thank you so much!
Thank you for taking the time to make this video.
Very helpful video. Thanks for taking the time to make it. I am no longer frustrated by these little beggars. Cheers........ Ian....
Thank you so much!!! Saved me hours of frustration. It was hope and pray everything stayed stable, until this video.
This is a great video!!! Thank you!🙏🏻
Really good man, super useful. Thanks.
long video but worth it! I'm finally crimping consistently!
Excellent! Clear and concise! Great job! Thanks
Good info and the close-ups are useful. I bought a WEL-202A and it's not up to the job. SN-28B now on order.
I'm usually pissed when I'm looking for some simple info and see a 20+ minute video where the instructor blabs about what he's going to show you instead of just doing it straight away but after smoking a joint and fucking up several connectors after watching several videos, I found your introduction very pleasing and had to pause the video to tell it to you. I'm going to light a cigarette now and click play full of hope that you'll show me just how to do it.
why dont you just turn the dies upside down inside the tool ?
Thank you for this -- you've saved me hours of frustration!
Hi and thanks.
Quick question: What wire size can are compatible with dupont connectors?
Thanks for this video! This was exactly what I needed.
Thank you Terry after watching your video I got it!
Very thorough video. Thank you!
Crystal clear! Thanks!
Muy buen video! Muchas gracias por compartir tu sabiduría!
Very well explained. I did it first time after watching
1
Thanks. Just saw another video and tried it that way and no such luck. After watching your video, got it on the second try (first try I didn't have enough wire).
Thanks!
Finally someone who seems to know what they're doing.
this is a great video god bless you
The wings of a Dupont connector are supposed to fold around the insulation and not to pierce the insulation. The SN-025 or TZ-4228B would be the right crimping tool. The SN-28B that you are using is intended for spade connectors
thank you. Very informative.
Fantastic. I was ready to throw my crimpers out. Thanks for the in depth tutorial.
That was great! it worked very well.
Excellent! I'm glad it was useful to you.
Good explanation Thanks 👍🏾
Nooooooo!!!! I messed with this for 2 hours trying to keep the little boogers straight and what a pain!!! So I sat down and thought about it. Then it hit me!! There's a reason they are on that strip!!! It's not to keep them together. It's so you can control them in the crimper. leave them on the strip!!! Then it's as easy as pie to place them straight up (or down, in your case) and keep them there until they're crimped!!! Hooooooorayyyyyy!!!! Now I can get on with my crmiping.
I would add a small caveat to this comment. For me this works great when doing the male connectors, but not for the female. Maybe I am using an off-brand of connectors, but my females are a little shorter than the males, and if I leave the strip tab on when crimping a female, the catch-tab gets crushed (meaning I cannot put the cover on) along with the wire portion. I find I have to break off the strip tab and seat the female connectors about 2mm in from the outer surface of the crimper (I use an Iwiss brand), and then they crimp beautifully. I believe "the pros" use separate crimpers for male and female.
@@splinesmith that's why I showed my partner this vid so she could do the fiddly blighters for me. She asked if she could help after all. Guess what shes getting for Xmas.
Very useful video. Thanks a lot. !!!
Very good. Does the SN-28B crimp both the insulation and conductor in one go, or two?
Thanks! Yes, the insulation and the conductor will be crimped in one operation.
Thanks Terry, camera went out of focus during that period. Thanks again for a brilliant video.
nice video!
if you are now before you shrink,
a male pin stuck in the female before you go shrinking?
then the copper wire can do not go further than that is necessary
success with shrinking!
friendly greetings from The Netherlands
Rob.
Yes, I do that all the time but not only to keep the wire from going in too far, but also to hold the connector in the right orientation. I do use a 90 degree angle male pin to give me some control...
Do you have any tips for then placing my crimped connector into the black plastic plug / socket? I’m struggling with that now. They don’t want to seat correctly in the plug. Thanks.
When buying pins - What is meant by "B-WIND - Right Payoff" and/or "D-WIND - Left Payoff" ?
wow I guess I did not save my previous comment, well, I will type it out again,.
Because this video was that helpful, only thing I can think of to make it better, would be a sort of "index" where someone takes the time to link to specific times in your video on specific topics in the video you hit on, so it can also be used as a reference to those who watched it before, and want to clue say someone else in, on a specific aspect that they might be missing info on, or something important to them, but they are harder to convince of just watching it all and spending the time, learning cause the time is well spent watching this video.
People have been burned so many times by disinformation, or misinformation, on the internet. very sad, that it has happened causing gems like this to get overlooked by many.
Anyway, thank you so much!!
I am just getting into using these for my 3D printer boards to have breakout cables for my drives, and such, to marry my 3D printer board, added on laser head and extruder heads to a CNC system that used a parallel port to give connection to the motor step and direction inputs, for much larger motors than the tiny motor driver boards you use in reprap style printers can handle LOL. Also you got another subscriber :)
(the main thing I got from this besides the specific form of the parts with those curves at the top and bottom of the cavity they form when pressed together, is that there is that level of thickness difference, will have to make two, since I have some I am using on ether net cable wires and the insulation is much thinner, and one for the stranded wire to go in my cable drag chains since it has to be able to flex many times, which has thicker insulation around it. Also I am making mine to go in a lever press fast as the hand held, not as mobile to do near something, but I dont need that, as it is going to stay still and I can add a couple extra contact points that hold things in place while I crimp so the parts dont move around until, it is all done, )
Thanks for watching! I'm glad you found it useful. If I get some time I'll try to put up some indices.
sounds like a pin inside a stand off bolt might help with holding the whole thing still and get an exact distance each time, unless I missed something and it moves the whole connector around, in which case then a slot maybe with a back at the side that the connector moves away from would be better, so you can lay down the tool on a board with said slot, place in the connector first, and push the jaws overtop of the connector and ratchet down to grab it as you showed, and place in your wire (pre stripped to length so it should catch once pushed all the way in) and finish the ratcheting job,
one thing I noticed about nearly all of the ones I was looking at, (bought one on ebay yesterday, so waiting for it to get here) is that the jaws that hold the connector in the crimper seem to be removable and replaceable or swappable, some have flat back looking form and others look like they are curved and formed to fit in the head, hoping mine are flat as I intend to try and insert them into a press I have (lever drawn half ton so easy to control) and try and make a jig to hold it all so that I dont have to worry as much each time I place them, that they are correct. will have to make a small video when done.
additionally it sounds like you could benefit from a video feed microscope like they use for electronic board repair lol.
please show how to crimp D-sub connector for the big size - I mean 10 sq.mm =7AWG. thanx a lot
Thank you! That helped
Thanks for showing me how to do this.
great. Thank you!!!
This video help me a lot. Now I know how to do it right.. Thanks ....
I wonder if we can remove the jaws and swap them over so the tool doesn't have to be held upside-down?
You don't have to hold it upside down. Hold it with the jaws above the handle (handle angled down), and insert the connector with the wings pointing up. That's the same relative orientation.
I still haven't gotten the hang of inserting the wire to the correct depth. I wonder if that's why he's doing it upside down?
I've added an index so you can skip to the good stuff
Great vid. 10x
Hmmm, your crimper looks different than my SN28B, which according to your 'heresay' is "the best". Actually, with my SN28B (from some Chinese source on e-bay) I can hardly make one good crimp out of five, so it would qualify as "the worst". The difference is not so much in the plier, but in the inserts that form the crimp. Your inserts are shiny while mine are black and look rougher and less 'well-shaped'. So I wonder where you obtained your tool (and at what price çuz we're all hobbyists.
When I bought my tool on Internet I tried to find one with good dies, but judging from a picture is difficult. Maybe there is an original good SN28B out there and I got a copy....
I recently found a Berg/Dupont HT-95 crimper in the scrapbin, it misses the contact holder so it is a bit awkward in use, but makes an awfully good crimp. Still, while crimping Dupont connectors I often wish I was born with three hands! Thanks for the video!
The word is spelled hearsay!
*my SN28B (from some Chinese source on e-bay)*
Well, I think we've found the problem. The quality of a *copy* has a huge affect on the results, as does experience with any given tool. So while a proper SN28B may be the best or just preferred by many (which it is) a cheap copy (from some Chinese source on e-bay) could easily be the worst and *not* preferred by anybody. There is no 'maybe' - you got a cheap version..
Somebody will correct me if I'm wrong - SN28B is probably a standard (like USB, E19, SAE 10-30W, whatever) for this specific type of connector. Various companies make the crimping tool to work with it. Quality will vary along with price points. You may or may not get your money's worth. You didn't.
Awesome
What size and type of wire do you use? Wire gauge, stranded or solid, and type of insulation (e.g., PVC, silicone, etc.)?
Did you figure out what size wire and casing or insulation, as I have the same question. Thanks
@@paddajunior744 He never answered the question.
great !!!!
Perfect
