Maybe someone here has a good idea:
For cost reasons, I planned all the push buttons (light switches, blinds, etc.) in our KNX house using a conventional switch system (so no "smart" push button terminals or high-end ones). To be future-proof (possibly for some network/internet-based control unit eventually), I installed CAT7 cables everywhere—so no 230V wiring.
So far so good... With this approach, I gradually wired the entire house. Now, in the technical room downstairs, I have about 70 CAT7 cables converging, of which I usually only need two conductors each. I don’t yet have a clever idea how to neatly terminate them. In my test setup, I just connected everything with a few Wago connectors.
In the distribution panel, all 230V wiring goes onto Wago TopJob connectors, which works perfectly for internal connections. But I don’t want to put all 70 CAT7 cables into there. That would be too chaotic. Also, I haven’t found anything suitable from Wago for this purpose.
So I need a smart terminal or wiring solution that can reduce the number of cables or conductors, making it manageable to feed into the distribution board.
I know this is very specific. Until now, I haven’t heard of anyone wiring like this. But maybe you have an idea of something suitable—perhaps from a different context.

I connected my control cables to Phoenix terminal blocks: 3213713 ( PT 1.5/S-3L) Those look good. They can also accommodate cross-sections from 0.14mm² (0.00022 sq in). However, the terminal blocks would need to be mounted on a DIN rail, meaning inside a distribution box. I actually wanted to avoid that, but maybe I should look for a smaller additional distribution enclosure.

An LSA distribution frame should also work. That’s a good suggestion—thanks for that! I wasn’t familiar with those. I only knew the classic patch panels from networking with LSA terminals. I’ll check if I can find one that can accommodate my cable bundle.
But now I at least have two solid options. From that (LSA) distribution frame, I would then run 5 x J-Y(ST)Y 10x2x0.8 cables to the main distribution panel. That should make things more organized 🙂

I ran Cat7 cables everywhere – so no 230V.Using this as a bus cable is rather a bad idea. Especially since CAT7 is more expensive than bus cable.
For the Cat cables, I would also use LSA connectors as already suggested.

There you already start with the problem that I don’t know any reliable terminal blocks. There are special bus terminal blocks; I have them in my cabinet.

Only the control cables have been my problem. Thanks to @world-e, I now have some ideas. I wasn’t aware of Phoenix terminals with the smaller cross-section before.
Now I need to work through these ideas in my mind first ;-)
