Amphenol connectors. Used a ton in industry, military and aerospace. They are actually really nice when you get down to it, but you need expensive tools and the connectors themselves are usually quite expensive. I once had a client ask for a specific 6 pin one, only about the size of my thumb, it was $800.

Yup, heard about it a week or two ago. Found it installed on my Samsung phone, it never asked for permissions or gave any info that it was added to my phone.
