I've come across a couple of connectors that would be perfect for my projects but i can't figure out how to design the mounting for it. The type of connector in the attached image is what i'm talking about. They don't have any screw holes and the side profiles are just straight so there is really nothing to grab on to so to speak.
Ideally it should be somewhat water resistant.
I know that there are great ways to design for these kinds of connectors since there are many of these kinds but i have a hard time finding examples of designs that implements this.
If anyone has any reference designs, ideas or can point me in the right direction i would be deeply greatful!
