I'm designing a system for a high-vibration application. I need to land wires on circuit boards. Someone suggested that I use a Wago cage clamp, and that there might be similar things from other manufacturers. The cage clamp was described as useful for this application because the more the wire pulls, the tighter the clamp becomes.
I'm thinking that this might be the same as a spring cage, tension clamp connector. Is it? Is either of these things the "correct" terminal to use for this kind of application?

Not having heard of either of these devices before, I did a bit of research into these parts.
To answer your first question, no, they are not the same part. A "spring cage, tension clamp" connector seems to be just an ordinary terminal block, which is not what you want.
As far as being the "correct" part, there seems to be no one solution to this problem. I am sure that there would be lots of ways of connecting a wire to a bord in a high vibration environment. The Wago cage clamp seems as good a solution as any, and looks pretty robust and well-made. I don't know how much they cost though, and it us probably worth looking around in case another manufacturer has a similar part cheaper and/or better suited to your individual project.
