Why 50% of All Crimp Connections Fail

Why 50% of All Crimp Connections Fail - Up or Down?

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.

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.

@maubunky1 2 ай бұрын

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.

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.

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 2 ай бұрын

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.

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.

This made my day, if you know you know.... This is incorrect, the seam of crimp must curl around the wires evenly, also there must be a insulated shrink wrapping over wire and crimp. There only needs to be the length of wire only the size of crimping area.

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!

@@stephenolan5539, during development.. seldom.. but all tools that required a measured force were calibrated periodically in manufacturing. After a Beta Level build, Manufacturing would typically outsource the subassembly in most companies I have been at.. but I personally still inspect - and pull - every one I do. - to ensure durability of the the connection. Too many times I have seen the blackened insulators and discolored plating.. on other's work.. so glad i learned it right. The only time I ever saw discoloration/burnt lugs on a prototype I built was on a special controller I built for a NASCAR team.. that was intended for 120 VAC 20A MAX. The uninformed gearheads would plug in 2X the load; 28 - 32 amps.. yikes.. HTH..

The example "problem" crimp nr.3 at 3:50 should be considered a perfect crimp. The wire should terminate where the insulation ends, wire extending at all onto the mating surface is considered a defect in all 3 product classifications according to IPC standards.

Nicely made video. I would caution that there are different methods for crimping insulated and non insulated connectors. A tug test should always be performed. While a proper crimp doesn’t need solder, I like to solder and add glue lined heat shrink. The seam is also very often the top in which the seam curls down around the conductor, such as in auto wiring, and spark plug wires. Those are open crimps and made using a two-step process - the curl, and then the crimp. I’ve never been a fan of insulated connectors, and much prefer removing the insulator if present, and using heat shrink instead. Happy crimping!

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.

The Ratcheting professional Crimpers have a huge crimping area on both sides so the orientation doesn't matter. It crimps the entire area of the terminal barrel.

@stevegraham3817 2 ай бұрын

The best option is to check how the Manufacturer guarantees their Connectors and Connections. They will have their own brand of tool, and it will be almost identical to the other Ratcheting Crimpers. Solid lugs maybe ok for Indent Crimpers, but the Lugs that are not a solid barrel will never pass inspection for any manufactured, built, repaired or modified wiring on any site, or on any piece of equipment. It's a good way to void your insurance as well.

After 40 years experience in the commercial and military electronics industry, if you don’t have the best reliable crimping tool, then solder the connection with flux, then clean with 99% isopropyl alcohol. But what about the crimp connector plastic? Use an un-insulated connector and add heat shrink tubing This is only my opinion and experience.

@NovaNinja_ 2 ай бұрын

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.

@user-ti1vs2qf3l 6 күн бұрын

Good stuff. This has been an area of confusion for me from before there was an internet to go watch helpful videos. I had originally concluded they should be done the other way, with the prong into the seam. This was based on examining commercially done crimps on things I had bought. On those, it looks like each half of the seamed side was rolled down into the crimp. I also noticed that some of the spots on the crimping tool have a pointed prong with curved edges that seems to match those rolled edges. I concluded that the prong went on the seam side. The pointed prong appears on the smaller size spots on the crimper, so I concluded that on the larger sizes, the shaped prong wasn’t necessary. I always use uninsulated terminals and heat shrink them, so I’ve been able to see the crimp, after I’ve done it. I was frequently dissatisfied, and usually ended up crimping connections twice, once from each orientation - that way I was sure one of them was correct! Ha! It has only been in the last year or so that I settled on crimping the way you described. I still learned I can improve by having a little wire stick out. Thanks.

@Imcrikee 2 ай бұрын

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

@TheTimtam112 2 ай бұрын

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. Also, the degree of which the actual spades of the connector is deformed is minimal (2:18 at 0.25 speed). If anything, the slightly overturned spades would provide an interference fit.

@Imcrikee 2 ай бұрын

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.

@MrItsthething 2 ай бұрын

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.

@richardhutchins240 3 күн бұрын

Important to note that higher quality crimp terminals are braised along the seam. I won’t buy terminals that are not braised-seam. The video is correct that the “tooth” should be opposite the seam, but braised-seam terminals can be crimped in any orientation. Also, I only use ratchet tools, specifically for ins vs non-ins terminals.

I've mostly eliminated the insulated ones from my toolbox, and have largely just gone with uninsulated ones and heat-shrink tubing. I find the end result looks better, and for certain applications, is even more durable. I've also recently started using Wago's wire stripper, model # 206-1125, which is absolutely excellent for getting repeated strips at the same length, and has the ability to leave a bit of the insulation at the end of the strip, so if you're doing a bunch of wires at once, you don't have them fray between stripping and crimping. It's sizing guide isn't as prone to slipping as the guide on any other stripper I've used, be it inline, "katapult", or perpendicular, which is, again, great for batches
