Crimped connections can suck for one reason that most DIY'rs have no idea bout. Should the connector seam should be UP or DOWN? How do I know wat size wire to use? Are manual tools really stronger? End the Crimp anxiety when you pull that wire and learn to crimp like electric Connectors, Insulated & Non-Insulated like a pro.

I have never done an inverted crimp such as you've just demonstrated nor have I ever had a problem with any of my crimps; not ever! The proper tool along with a good set of eyeballs and technique is what gets me through this type of ordeal. I would never do an inverted type of crimp unless you follow up with flowing solder into the joint and over the outer split connector joint on an uninsulated terminal. Sorry, but doing an inverted crimp does not nor will not get it for me! I could actually demonstrate a solid crimp whereby it would be 100 percent of impossibility of not being able to pull a wire out of said crimp without breaking nearly all the wire strands first! And so I stand by my crimps by at least 200% without any common failures what so ever!!! The crimper that I used back around 24 years ago withstood 10 whole years of use and abuse and so if I could remember the tool manufacturer's name and P.N. I would give you that info right now!

​@@deslomeslager Always, always establish a good physical/mechanical connection (crimp) before you solder. Then, Depends on the application. Most people over solder. You only need to wick into the conductor and get some flow to the connector. I prefer some, but minor stick out of the conductor when pushed through the connector. This allows you to place your iron so that you heat the connector and the conductor at the same time. You don't want your solder to move outside the connector as it can lead to embrittlement in a high vibration environment. In a high silver content wire you can even get hydrogen embrittlement. Less is more.

Another potential issue, primarily with the insulated connectors, is getting some of the wire insulation into the crimp. Using the right size connector, as you pointed out, can help avoid that because only the wire will fit. But if the wire is in the smaller range for a particular connector, it is possible to get some of the wire insulation into the crimp, and then it impedes a good connection and it’s difficult to notice if the connector has an insulated collar around it.

What you say is correct but If you buy brazed-barrel crimp terminals this failure mode cannot happen. They cost a lot more than the cheapies but are worth it. They often are made from thicker copper material, so they are sturdier. Nylon insulated terminals are good to higher temperatures than the cheaper PVC insulated ones. Many critical applications specify brazed-barrel terminals. For smaller screw size terminals 1/16 stick out of the wire may be too much. Any wire past flush is not part of the connection, so just make sure the wire strands are just a little past flush and not in the way of the screw head. Ratcheting crimping tools are great and often take a lot less force to crimp. I have carpal tunnel damage from crimping terminals and cutting wires with less than the easiest tools over fifty years of tool use.

Thank you Walter. Also people should avoid generic no name brand Chinese made crimp terminals widely available at online stores because even though they come in very affordable multi-packs with every size and style of crimp terminal you'll ever need in one convenient box.....video demonstrations have proven that they don't hold their crimp even when crimped correctly, to the point where just a slight tug on the wire pulls the terminal right off. By comparison, Gardner Bender crimp terminals hold together very nicely. I'm not sure what manufacturer makes the best brazed-barrel crimp terminals or where is the most convenient place to buy them but I have to find out before my next project.

Couldn't agree more. High quality terminals, and a high quality crimp tool are so worth it. I've been working on industrial machinery and building control panels for 40 years. Panduit or T&B are the way to go. I own both a Panduit CT-1550 and a T&B ERG 4001. A lot more expensive than most of the other tools on the market, but when a bad connection results in downtime and/or a call in the middle of the night, then they seem rather cheap by comparison.

Although technically your using uninsulated crimpers on insulated terminals, you are correct about the orientation which is easy to see by looking down the inside of the terminal. Insulated crimpers are what typically result in soft crimps, also good quality terminals have grooved interiors that help with getting a good bite on the wire, unlike the cheap Chinese terminals which are usually smooth.
@heartysteer8752
@heartysteer8752 3 месяца назад
I've been doing this method using uninsulated crimpers on insulated terminals for decades. Rarely does the crimper penetrate the insulation. If it does, it's just a small area inside a depression that is still protected from contact with other objects. For low voltage it's not a problem. For line voltage there might be some added shock risk but usually the compromised area is on the backside of a terminal so it is still protected from accidental contact.

@kh40yr

I lessoned myself about 30 years ago in getting the crimp right, and using the correct heat shrink tube. Insulated connectors have the insulating shell removed and thrown away, and crimped properly as shown. You can get the uninsulated solid tube butt/end connectors at Napa usually, or any Commercial truck supply store. Ancor Marine Grade heat shrink tube only, all I use now. No more Harbor Frightening Chinashrink. The Ancor is expensive, but you'll thank me later. When shrunk properly, it will ooze sealant out of both ends of the shrink tube on the wire or connector., sealing and locking the connection. You could tow a vehicle with the strength of that adhesive/sealant. I made my own crimping tool because I was tired of folding the china crimpers over, when I would squeeze tight. All big high amp connections get a hydraulically crimped end, and solder and Ancor. You can also get the shrinkable butt connectors and others at Napa. Most of those are junk. Don't buy them. Some of those better marine connectors do both with a shrinkable insulator and being loaded with Dielectric grease from the factory.

On the hydraulic presses, once you did the initial setup for whatever wire gauge and terminal, you had to do a "pull test". We had specific machines for this, that would pull until failure. We had specific rates for what each should fail at. Some manufacturers asked that we solder the terminals as well. When I do this at home , I always solder them, because I was so use to having the pull test, and I don't have access at home, so I solder it lol.

Don't use solder in automotive applications, as it can crack under vibration. A properly crimped wire is bonded to the connector, and solder is just a point of failure. The exception to this is when potting the connection, as the sealant prevents the solder from cracking or separating.

Thank you for making this. It seems like such a simple solution. Nobody ever told me they needed to be spun the proper direction. I always wondered why I'd have to do it 3x to finally get a good connection. Here I just by chance would end up with it turned properly.

You covered a great topic and glad you showed it done the right way, NICE JOB. If I may add, I ONLY use Ideal crimp connectors with either a ratchet crimper or a Klein regular crimper to get the best results. Whenever I rewire any kind of automotive application, especially boat trailers, I remove the insulation off the connector, slide 2 pieces of heat shrink tube with the last heat shrink to go on being a little longer before I crimp my connection. Last, all my crimps get sprayed with white lithium grease before I heat shrink them. Truly a long lasting, almost bullet proof connection. Hope you like the method to my madness. Mike. :)

try double-wall heat shrink with a melt-liner you will marvel at the finished connection. That single wall heatshrink you are using will probably split with age. When you heat the double-wall you stop heating right the very second it oozes out. This also serves as limiting the heat applied.

@@cruze1953This is exactly why I use 2 pieces of heat shrink, 1 longer than the other. Lithium grease under the 1st heat shrink, and the 2nd heat shrink overlaps each end to seal in the grease. Over heating heat shrink makes it brittle and a very good point. I will look in to that type of heat shrink that I am not familiar with. Thanks!

Excellently done video. For me, sometimes crimping just isn't enough. Like when you are repairing wires behind a dashboard and re-accessing them would be a hassle. When I need a bulletproof connection like that, I remove the plastic insulation, put heat-shrink tubing on the wire, crimp properly as demonstrated here, then Silver Solder, then finish with the heat-shrink tubing. That will last forever!

This! I tried to teach a new boss this once and he wouldn't listen, until I started going over to the bench where he was working and easily pulling off 2/3 of the terminals he had just crimped. Another bad habit of his was to strip the wire too short, the crimp (even when properly oriented) would only pinch the very tip of the stripped portion of the wire... also easily pulled off. My agency wouldn't spring for good ratcheting crimpers but at least I got them to throw out the trash Radio Shack crimpers (like the first pair you showed) in all the toolkits for a fairly decent Ideal 30-429 that had dies for both insulated and bare terminals. I used my pair for nearly 20 years, crimping thousands upon thousands of terminals, and I took them home with me when I retired. Good video!

The right crimp for the right wire, the right tool and correct preparation will make a long lasting crimp every-time. I can say that because I am one of a handful of EWIS, Electrical Wiring Interconnect System, experts on USN/USMC, a few USAF an a half dozen foreign military aircraft. If you’re going to do more than a dozen crimps in a year and you can afford it buy the ratcheting crimper. You’ll get interchangeable heads and you won’t be able to crush the crimp like so many do. It really takes about 15 minutes to train someone to be able to properly one crimp after another. Other than the lug breaking I can’t remember seeing a failed crimp in years.

There's also a right way round in a ratcheting tool for insulated crimps: there are two sections in the crimping die, one for the insulation and one for the wire crimp, and they are different sizes (cheapo ones sometimes are not). Crimping is all about compressing the materials into their plastic region without passing the yield point. Understanding this allows you to appreciate why you need many different size crimps, each of which only accommodate a small range of wire sizes. Remember that a crimp done properly is mechanically superior to any other type of termination. method.

Great post. After 43 years of doing crimp lugs, I concur with your observations. It would've been nice to show not only failed and poor crimps like you just did.. but with high current connections.. the TIN plated with insulated connections.. the plating becomes destroyed by the heat due to higher resistance from the bad crimp, creating more resistance.. cycle, repeat.. until at some point, lug gives out and either fails.. or flames.. or both. THAT is the big danger with crimp lugs.. necessitating as perfect a crimp as possible. As one who went through multiple UL, CSA, TUV, cUL, and ETL certs for products.. it was important that we had to get this one right. Thanks for a great, concise, video!

Good tip. I used to do this in the commercial marine electronics industry. I would crimp it then solder it. I didn't clean them though, I'd just use RMA flux core solder (or no-clean but I don't really care for that stuff). I stopping soldering them because I found they only ever corroded when there's water in the wire and the wire is ruined anyway. Or it corrodes around/behind the connector and you have to redo the connection anyway. But I still believe soldering the connectors is good practice.

I am not agree with you on which side of the connector facing the crimping claw of the tool. Crimping the connector your way will deform the connector itself and cause poor connection, thus overheating ... The claw of the crimping tool should fold the two edges of the connector from end to end. In order to achieve that, you should crimp the connector two to three times depending on the size of the connector

Have you tested whether the connection is poor? If you want to refute a video that provides evidence, you need evidence also. Post a video if you feel so strongly.

I read my comment again and I agree with you all because I was not very clear. If your crimper is with pointed claw, then it meant to fold the opening of the connector. If your crimper has a rounded claw like the one in the video, then the rounded claw use to pinch the connector as shown in the video. However, the rounded claw should be placed in mid part of the barrel so that it won't deform the connector. Also, you can see in the video 2:20 incorrect crimper iused thus deform the connector. If the connector is a male or female spade deformed then it will definitely won't pass quality control.

Here's how I use crimp connectors: 1. Remove insulation and put a piece of heat shrink over wire. 2. Crimp each ear of the connector down, one first, then the other on top. This keeps the connector from deforming like it does if you crimp from the back. 3. Heat the connector with a lighter and put a little solder on the tip of the wire allowing it to soak in between the conductor and the connector. 4. Apply heat shrink in same spot where connector insulation was. You can't beat it.
