Does anyone else use Krone blocks as a means of connecting wiring together?

Does anyone else use Krone blocks as a means of connecting wiring together? If you don’t know what a Krone block is, it’s the white thing with all the wires hanging off it in the picture.

I use “European style” power terminals from radioshack.

Yeah, I use those too for things that get disconnected regularly. The Krone blocks are useful as you just use a punch down tool to terminate a cable and that means there’s no wire stripping or fiddly screwdriver action. You can also ‘double punch’ 2 wires onto the same terminal meaning you can then daisy chain a single 12v feed for instance. I assume I can’t be the first person to have thought of using them…

@ThantiK we call those Lüsterklemmen, and they are generally a poor choice for connecting braided wire if you don’t crimp an endsleeve on every single wire.
@Tim_Rastall are those blocks self-cutting? Google doesn’t turn up any results as @Krones_AG is also a large supplier of beverage production machines.

@Thomas_Sanladerer try looking up IDC, that’s generally the term used for that, insulation displacement connection

@Thomas_Sanladerer http://en.m.wikipedia.org/wiki/Krone_LSA-PLUS
The blocks aren’t self cutting but the tool you use has a little pair of snips on the end. All clever German engineering btw. You can buy 'clone ’ blocks and the Krone tool from Aliexpress for not much.
(edited to remove duplication of what IDC stands for)

I believe terminal blocks make wiring easier and more organised.

Oh and now I have finally learned what LSA-PLUS stands for: Lötfrei, Schraubfrei, Abisolierfrei, Preiswert, Leicht zu handhaben, Universell anwendbar, Sicher und schell.

I use the same blocks as @ThantiK . The first time I built my printer I spent a lot of time crimping ends and tying the wire up nice, but re-doing all that with every modification got old, so now I don’t get much fancier than zip ties :slight_smile:

In Italy the blocks named by @ThantiK are called “Mammoth”… I don’t exactly know why :slight_smile: :-). In our printer we try to reduce at maximum the extended wire to avoid this and every wire is terminated only on the motherboard, but I need to find some useful connectors for extending motor wires… The “world of connectors” is very large! For example, to terminate wires that need connection to classic 2.54 male pin header, what do you use?

I also use the same type of terminal blocks as @ThantiK . We call them sugar cubes. I don’t feel totally happy with them when using thin wires even though they have been working fine so far.

@Tim_Rastall I’ve been meaning to try them out since I am planning to rewire most of my cabling with CAT5-cabling.

Another thought is using patch panel sockets like this in both ends and conenct stuff with crimped CAT5 cabling but I don’t know if the connectors and sockets are up to the task. I know Makerbot switched from that idea long ago, but havent read up on why;

Edit: I believe a better term is Keystone Jacket

We also call them sugar cubes. Tinning/soldering the end of the wires make them a bit more reliable if you don’t have ferrules. (Which now is on my eBay watch list after reading @Richard_Horne 's latest blog post).

I thought about doing this I just didnt have a good place to mount it to. Great idea though as getting out the soldering iron to connect wires is getting a bit old at this point :smiley:

I have to go to RS today for wire so I’ll check out @ThantiK 's power terminals.

These seem to resemble telephone punch down blocks. I think punchdowns are nice for signaling applications with solid wires, but not quite so nice with stranded. And, they’re generally not meant for high currents.

@Joseph_Chiu yeah, I had my doubts but telephony is only one several applications for LSA-PLUS. They are perfectly serviceable for steppers, ends tops and thermistors.

If money isn’t an object, phoenix connectors are great. They’re essentially connectors that have terminal blocks for the wires to terminate in. Absolutely great for prototypes, but rather pricey. The good news is that they are completely reusable, so they can be reused in a new design without any recrimping

@Eric_Moy - Phoenix is the recognized leader, but there are other companies making compatible “Eurostyle” removable terminal blocks. I was just talking to a vendor yesterday about how Phoenix gets a large premium… Those removable blocks, while a bit pricey, are so worth it, if you anticipate having to connect/disconnect your cabling often!
