Is there a standard that all DC power jacks follow? More specifically, I plan to use 5.5/2.1 mm barrel, and I've found a bunch of these components on eBay, but they all lack drawings (not to mention 3D models).
I've found a 3D model, but it does not fit to a footprint of one commercial component that I've managed to find. And that is why I'm asking for a standard.
For example, this component

does not have a drawing, they only state that it follows the IEC 60130-10 Standard, but I wasn't able to find drawings for this standard.
