Would make it less modular, at least production-wise. But! The last "wall" stopping the "daisy-chaining" undead could have some elongation to stop misaligned attempts.

[@MrMartinSchou]

I think that would make them more expensive. It looks like you can just swap out the lever as you want, which doesn't work with your suggestion, because you could just swap the lever to another colour and things would now be massively frustrating, and you'd be ripping your hair out trying to figure out why the blue won't connect to the other blue.

[@oasntet]

These are so close to being fairly cool. I was also reminded of the anderson powerpole action for the plugging two connectors together, though I feel like those make a more solid connection with a lot of copper-on-copper and self-alignment features. Perhaps if they had realized the misalignment problem and extended that end-cap piece to overlap the other side, it'd prevent most misaligned connections. Or an outer shield that also has to be aligned, a bit like the 4-pin Molex. Maybe a fun 3d printing project?

I got a bunch, and they are wonderful for low voltage electronics protoyping situations, also because the not keyed and can be abused becomes a benefit.

They might be ok for bench testing applications. I wouldn't put them anywhere permanent/out of view.

The Anderson versions have a steel spring backing the contact so "pushing past the bump" does not compromise the contact pressure, and indeed the wiping action is part of the self-cleaning property of the Anderson.

@@Woffy. The problem with that suggestion is that they'd have to design and produce a second body part, diving up cost.

The could easily add a "key/finger" to that closing plate that you put on the final position of the stack to eliminate the misaligned insertion issue. But, as many others have commented, I'd really like to see some current/temperature tests on these things.

[@Pystro]

Yup, the mis-aligning risk could be _lessened_ if they made the end plates stick out next to the non-directional plugs. That way, you could only offset the assemblies in a _single_ direction. And to mitigate the risk from that, it would just be enough to always put the incoming live and the ground that goes to the machine onto the connectors that would remain unconnected. (And by elimination, the neutral wire would go in the middle. ) You just have to be able to trust that what you call "live" is indeed the wire that carries a voltage with respect to ground.(*) (And as long as the incoming/outgoing cables are wired into their intended sides of the assembly.) In fact, I think this order should *always* fail safely, even if you shifted the connection one place in the other direction (as long as the appliance doesn't have a fault). (*) Another reason not to use these for any place where some other electrician can get their unqualified hands on the system.

[@HDRW]

The hermaphrodite "bumps passing in the night" technique for mating contacts is what Anderson use for PowerPole and other connectors, which go up to 350A (if I remember correctly). Advantages are that parting/mating them scrubs them across each other, doing a bit of cleaning, and by the initial contact/last break being on the forward faces, but the live connections on the rear faces of the bumps, means that any arcing won't be on the surfaces carrying the live current - not that you're supposed to mate/separate them when live, but people break rules 🙂

[@BoB4jjjjs]

I would use them for 24 volt heating connections, they would be very handy for these type connections. However, I would not use them for high voltage or high current applications. With a bit of improvement, they would be very useful, but limited at the moment. But that is basically what you said anyway.

I use wago 734’s for that type of application. It works about the same except you use a little tool as a lever instead of the lever being a permanent part of the connector. You can pull them apart and snap together more slices to change the number of pins if so desired for the female connector, but the male connector cannot be easily modified. UL rated for 10 amps (300v).

Exceptionally good advice. I would be interested to see what would happen to the plastic if you put a soldering iron tip near it. Some plastics have a higher melting point and I could bet that wago ones offer better high temperature tolerances.

[@foogod4237]

The dumb thing about the "offset" problem is that if they had actually made the cover plate at the end longer, so it extends down the edge of the plug connector, it would actually prevent you from being able to connect them up in an offset way. They apparently just never actually thought of this or how to protect against it. These could be cool for lower-voltage low-current applications, but I don't think I'd trust them with mains voltages (even in the US) or with anything more than an amp or two of current. The overall idea is kinda neat, but the implementation just seems like it may not have been through the amount of refinement and testing really needed for this sort of a product in that sort of application. As you quite correctly pointed out, one of the really good design features of the WAGO connectors is that the contacts are designed to "fail closed", so it is actually the natural state of all the metal components to hold tightly onto the wire (and you must apply force _against_ the spring to open them). This means even if the plastic bits of the connector fail (or even melt) it will still continue to hold onto the wire securely anyway (there are actually a few videos where people have pumped way more than the rated current through them, and all the plastic around the connector basically entirely melted, but it still maintained good electrical contact anyway). These connectors rely far too much on their plastic bits for actually exerting necessary forces, and plastic under stress can fail or deform for many reasons (sometimes not even if it's overloaded, if for example it just gets too old, or too warm, or too cold, or comes in contact with the wrong things, etc, etc). No good electrical connector will ever be designed to rely on plastic under constant force for its proper operation. Doing so is a huge red flag.

[@iggysixx]

On AEG power tools, the 18V and 14,4V batteries are different in length. The connectors are literally identical, BUT... The "rail" that guides the battery connector to the connectors on the tool is simply longer on the 18V (or 'elongated' if you will). This very simple difference results in the 14,4V battery comnectors not reaching an 18V receptacle (because the 'recipient rails' it slides into are longer). And an 18V battery connector can't reach a 14,4V connector because the rails on the 18V battery are too long for the 14,4V recipient. (Fits like a glove, but reaches the end before the connectors can mate) Such a simple an elegant solution, I feel. As per THIS connector shown in the video; there could be 'crossbars' between the female connectors - one at top side, one at the bottom side (and mirror image thingies between the male connectors) that would only allow them to connect when all 3 pins line up

I think it could be safer if the earth modules had their connector mirrored, providing a key and making it very unlikely that a current wire be conected to earth. Doesn't stop L/N swapping, but if the recommended layout is separating L and N with an earth it would be mostly avoided.

[@johndododoe1411]

Because opposites will be mirrored, plugging two identical power sources together with the yellow earth keyed would still mate, yet short live to neutral twice as solidly as the plug can normally connect! A keying that has one plug upside down would avoid that and also allow a simpler shape of the bronze spring plate .

[@dougerrohmer]

I think the end plates should extend and be made in a way that if you misalign the connectors the end plates interfere. (Please contact me directly for my royalty cheques).

On the modularity aspect: it seems you can pre-fabricate cables with eg three leads, and then combine one end into a bus by peeling off the lid and joining multiple connectors. Useful.

I’ve been using some Wago clone connectors in the building of my 3D printer. They are modular like these in that they may be connected together in order to create any number of wires connector required but they don’t disconnect in the middle. The hole to test the connection with a multimeter is in the middle of these. For permanent connections I’m switching the Wago clones to the heat shrink wrap with solder in the middle and for non-permanent connections I’m using JST XH connectors. Connections to/from the power supply are done with spade terminals or disconnects. Except for a fan or two, which are 5V, everything is 24V after mains electricity goes into the power supply. The Wago clones are great for quickly setting up tests before finalizing everything.

[@davidg5898]

I see now what you meant (in your reply to my comment on your short) about their modularity being more difficult to key, since it can't be done on the prongs while keeping the modularity. But if the end cap pieces were extended to the full length of the prongs, that would prevent offset connections (so long as you used the same number of modules on each side).

[@aaronlandry3947]

I think the simpler fix for these modular connectors being able to be connected out of sync with each other would have been to have each color key differently. Meaning that they come in pairs and the connector rod has a particular shape that can only push into its partner that it's paired with. Similar to how power connectors on a typical PC are keyed. So in this instance with three pairs of colors you can have One completely circular one completely square and one half circle half flat like a dome. This way when you try to fit them back together they should resist plugging in to things that aren't keyed to its mating pair.

[@miketrissel5494]

You've got a good point about pushing past the optimum pressure point as they click together, but couldn't help but notice, that with the angle of the connector surfaces, there is going to be quite a bit of increased surface area, copper to copper, as it advances beyond the peak pressure point, They may just have had a little bit more insight than were credited for. 🤐

Thank you for your thoughts, I agree personal non-plugged sockets only, also plastic and not rated I can understand.

I really worry about the popularity of these wago knock offs. They are fine for low volt projects but I'd never trust them for mains.

As a concept design, I think these are... interesting. I do like the modularity of each connector, but as noted, some security and rigidity issues need to be addressed.

[@tonysmith7283]

Among many excellent diagnosis and comments regarding spring contact designs and their engineering is a consideration of what makes a reliable junction … disregarding plating thicknesses, barrier metals and direct but inadvertent submersion in aqueous solutions ( spillage, humidity and sweat for example ) is the concept of a gas tight contact area where the normal force Between the joints is sufficient to prevent atmospheric air to ingress … the contact normal force … the pressure exerted by the mating contact areas … is sufficient to provide contact to contact low resistance over the lifetime of the contact … and to keep air from migrating between the contact surfaces.

[@PaulSteMarie]

The connector tab looks very similar to those on Anderson Power Poles, which are rated for 30A when paired with appropriate wire. Going past the peak is a good thing. When they slide together, it provides a wiping action to clean the contacts, and the two sloped sides give a much larger contact patch than the peaks would.

[@matthewmiller6068]

The one major difference though Anderson connectors have an additional piece of spring metal under the connector which ensures it is always pushed tight against the other mating surface

[@ehsnils]

Some notes here: The connector part of it where it overlaps and clicks into place it's quite similar to the Anderson powerpole connectors. Not identical, but works on the same principle. (I'm using the SB50 connectors in several places) Each color should have its own keying to prevent the "offset" issue and allow for building truly unique connectors. But they seem to be a nice basic idea though.

[@Lizlodude]

Interesting design. I'd imagine you could at least partially solve the misalignment problem by having the cap piece extend into the connector area, similar to a JST-XH style connector, but you would need end caps on each side of each connector. The 32 amp rating is hilariously terrifying though.

[@HardwareHarry]

Could the manufacturer address the potential for misconnecting the two connectors at an offset by making their "clip on" panel to have a longer piece which goes across into the same space on the opposing connector and only allowing connection where the correct pin is aligned? In some ways I love to see people try to produce a similar project but include their own tweaks and "design enhancements", rather than just trying to produce a rip off version of an existing product but cheaper and almost always inferior. I guess that sometimes the evolution is an improvement, other times it's dangerous and you have to look carefully at each product version . Thanks Clive, very informational video as ever.

[@johndododoe1411]

An extended end plate would only stop misalignment in one direction . If system is redesigned to always have live on left, the end plates would be on the same side and collide .

[@ManWithBeard1990]

There's a lot of potential here, I do like the basic idea. I agree it has a few issues but I believe most of those could have been avoided if the design was only a little different. I also kind of like how the lever works when compared to Wago. On one of these if you've used a wire that's too thin, the lever will give you that kind of feedback because it feels loose. On a Wago connector (I use the 221's, usually) that is spring-actuated and you use the lever to release it. That's the opposite way round, so it always feels like there's tension there even if (actually... especially if) the wire isn't being gripped all that well. Sure, the Wago will keep on going if the plastic has melted, but if things get that far, your connector acting like a fuse might not be the worst thing that happens to you that day.

[@steubens7]

were there dummy sections available? that's usually how modular connectors and switches end up keying things to avoid the dislocation problem. could do it with different style end caps too. they get to hang out a bit on the side

[@interdimensionalsailboat]

So, if i understand correctly. Giving the modules more structurally sound materials for the grippy bits under load and make the modules keyed and shielded from one another to prevent accidental electrocution and this could be a sufficiently safe, viable product with a practical use? It sounds expensive but still, perhaps its worth it somewhere like you described!

[@daviddavidson2357]

As someone already said, keying them would make them safer, but you could just key the earth so only earth can be plugged into earth, that will eliminate most mishaps that are dangerous to the user. I've seen American videos saying to wrap electricians tape around the levers on Wago 222s before putting them in a backbox so they don't open (I've never found that legit 222s would open easily, even if they caught on something and you should always pull on the wires after installing to be sure it's done right) so that might work to hold these closed, unless they melt. Changing the lever to make it fail-safe like Wagos would be better. I assume having the lever act as a retainer and not a spring 'loosener' also makes these far less reliable than the Wago connectors in areas with heat cycling and vibrations, probably barely better than the old screw down terminal blocks *after* taping the levers down. Making the connection better when plugging them together is hard to think of in my head and harder to put into words, but an inverse * or + shaped hollow piece of metal that's sloped and flexible enough to deform in one direction or the other may work, add a detent to the ends and a small pip to the tips of each blade in the hollow star shaped piece of copper may allow it to bend the click in place with more connectors than just 1 per wire. Might require a lot of force to push together and pull apart though. Another option is to add a second connector to the side of each one (horizontally and vertically) so you get double the connection area. Or just have them marked A and B for a male-female arrangement. You're always going to use 2 of them together anyway, so making them that way would work. Makes it a bit harder to use them in something where you may want to swap a love one around for different things though, but that would likely only be used in lower voltage hobby stuff.

I see that they've modeled the mating connection off of Anderson Powerpole connectors.

Great review as always.....but no UL or CSA (a Canadian accreditation organization) = no bueno

[@dcallan812]

Ok for low current home use, but the tree way should have some form of key system to stop it plugging into the correct way. Interesting look at them I know to avoid them now Thanks 2x👍

[@patomahony9747]

Thanks Clive. Nice review

[@frankhage1734]

It seems like the designer could provide end plates which have a locking clip that extends past the connector ends and has a receiving plate with the latch pip that captures the clip. If they were on each side, then the connector could not be assembled offset and there would be some mechanical support for keeping the sides latched together.

Very interesting for me who used to build whole industrial grade switching cabinets from the ground up. Thanks for the upload! Did you ever use connector components from Phoenix Contact? Amazing, well thought through, but very pricy. Stuff works like a Lego system - nearly endless flexibility to combine their various components. Original a German company, now manufacturing in over 10 nations though. So one has to wait and see how that goes.

[@TheTruth.K.J.V.]

QUESTION?? Can one of the units be reversed? Making one of the slots male out of the set...thus must be aligned correctly to mate?

[@bigclivedotcom]

They're all symmetrical.

[@thepcmaniaccc]

It will be interesting to compare the contact resistance of these vs the original.

A Wago, Phoenix and an Anderson Salesman go into a Bar, they discuss their products. Wago: our spring loaded clamps have a nice lever to use without tools but they arent flexible Phoenix: our SC2.5 and SP2.5 spring loaded modular connectors are incredibly flexible to use. They can even be keyed. Anderson: our connector may need tools and is not very flexible but we only keed the shell and 2 connectors which saves a ton of money for production and logistics Some Chinese businessmen on the next tabel: Write that down, wrote that down

[@terrym1065]

Good job Clive. Certainly not Wago or Ideal quality. Melting plastic smells bad too...

[@ovalwingnut]

My God man You put the R in Rembrandt. Pure digital, high gloss, rasterized excellence & goodness Just saying. Now I need a cigarette! And oh yeah. Another GR8T video! But don't let that go to your head

[@GeekRedux]

Close to being great. Those side caps could easily be redesigned to keep a misaligned connection from happening.

[@UpLateGeek]

They could fix the misalignment issue by keying the different colours differently, so you can't connect a blue to a yellow or brown, only to another blue. The connection from module to module could be fixed by making the plastic connectors themselves click together rather than the metal contacts, so the contacts don't have to slip past their highest spring point. Or there should be some mechanism that applies pressure to the contacts after the connectors click together and they've slipped past each other. As for relying on the integrity of plastic to maintain a good connection, you'd pretty much have to adopt a "Vago" style spring contact, which may be difficult if Wago has patented it (not that it's ever been a problem for the Chinese manufacturers before). Either that or mitigate the problem by using a high-temperature plastic or one that otherwise doesn't soften/deform due to heat. Or you could just spend a little extra for the genuine Wago connector. There's a reason why they cost more, and I suspect if you fix all those issues with the cheap one, they wouldn't be quite so cheap anymore.

[@generalmisery]

They seem to be perfect for projects like RC vehicles or similar things that benefit from easy connectors.

[@MrFujack103]

Clive what hand cleaner do you use?Swarfega made my hands like yours!

[@bigclivedotcom]

I think it's just the ravages of time. My skin often gets dry and cracks in winter.

[@MrFujack103]

Oh I see. Sry I thought maybe you might of used it at work as a lot of company’s do. Was going to recommend Manista for anyone that finds other aggressive. And no I don’t have any affiliated links. Lol

[@Stelios.Posantzis]

Interesting concept. Looks quite flimsy on the negative side. Seems very handy for quick prototyping on the positive side, e.g. in a project where you haven't quite decided what types of connectors you will use and you know you will need more than a couple of types. I'd consider them for low voltage and low current (both conditions met at the same time) applications. I don't like the fact that the spring is not permanently connected to the bar conductor and that its tiny pivot is made of plastic They don't look like they would last for decades in a permanent installation. Perhaps in a low voltage, low current installation that might be acceptable in certain cases, e.g. a small, low-powered battery toy.

[@acmefixer1]

I would like to know what sizes of wire it's designed for. One video showed the Wago handling very high current and not failing. I wonder what the maximum these are rated for.

[@DorsetSaferRoads]

Let's see some destructive testing of these connectors. Let's see them work at 32 amps. Good use for the flir camera 😁

[@transmitterguy478]

The wire only makes a small thin connection with the connector electrode. A wire nut makes a far better and safer connection. 32 amps current carrying capability, I don't think so. The contact will get hot and melt the spring pivot and a fire will ensue. 5 amps is all I rate it for. Great videos Clive! How's your brother doing?

[@a.lisnenko]

Clive, please test them at max rated current.
