What terminals to use for stacked boards

LukeBarber

I'd like to stack a bunch of boards with terminal blocks on the edges of each of them. The boards are stacked with only 10mm of spacing in between them. With regular terminal blocks, the screw terminal is inaccessible once you stack the boards.

What's something that works like a terminal block except lets you adjust the tightness on the edge as well?

I was looking at Weidmueller but was wondering if there's a better solution out there?

Look for "Screwless Terminal Blocks". Weidmuller has some nice ones, but TE, Wago, Phoenix Contact, etc, also offer many. Looks like most fall in to the 11-13mm range for height.

Here's one that would probably work:

Pololu also has some no-namers, but too tall, (12.7mm)

You might want to search for "pluggable screw terminals." Here's a diagram:

PhiPi has the answer. These are showing up in all the new stuff in my industry. As for the Wago screwless spring terminals, the 0.1 inch pitch ones have a distressing tendency to self-destruct in use aiming a spring at your eye (which you can never find to reassemble the terminal).

I love those pluggable screw terminals.



The two most common sizes appear to be 5.08mm pitch and 3.81mm pitch.

I started using these a couple years ago and I like them much more than normal screw terminals.
