Hey all,
Can anyone help in identifying these terminals?
I haven’t come across these before, and it’s not clear how the retention mechanism works. I’ve already broken and lost the orange clip from the AUX terminal by playing around.
I need 0V and OSC to connect a smart relay to my garage door. I can’t afford to break another…
Thank you!
Those are 100% spring terminals as the other person mentioned. I use these in my designs, you’ll need to press the orange buttons quite hard as they’re meant to work even in rocketry applications where bolted electrical connections may loosen.
When you press the button, you’ll still need to apply mild insertion force. These work either with solid core wire, or stranded if the stranded wire has a ferrule crimped on.
Shows how pressing the button bends a metal tang away from where the wire comes in, the little area with a squiggle.
Thank you! Something concrete to go on. Is there a specific name these go by? I couldn’t find them by searching.
I think I have two issues to work through. I’m not sure I applied enough pressure to actuate the spring (access may be a limiting factor in-situ), and I was using an extremely fine gauge of wire. I doubt it would have the stiffness to push in.
Would a stalk lug work to provide added stiffness to the conductor, or does this terminal expect something malleable?
The green and orange colors are quite typical of the phoenix contacts brand. It’s not a perfect match, but this model is very close: https://www.phoenixcontact.com/en-us/products/printed-circuit-board-terminal-sptaf-1-7-35-il-1861988
These are made by te connectivity, horrendous datasheets, but pretty good products. I’m more a Phoenix man myself but you work with what you’ve got in stock: https://www.digikey.com/en/products/detail/te-connectivity-amp-connectors/1-2834011-4/5872966
The drawings are found towards the bottom of that page, scroll way down to see “product drawings”.
I don’t think these care about malleability too much, they’ll pinch whatever you can fit into its maw.
This is what people in my field mean re ferrules:
Good luck, glad I could help 👍
That’s great. Thank you again!
