Too big plug and cable

I want that.

I suppose I'll need to find the adapter for that plug though. Pretty sure there's one in that cardboard box behind the old modem in the back of my closet under the basement stairs.

we have cabling like this on our automated testers, although they use a (huge) nut-like thing to press the contacts together. Big circular connector with nearly finger sized contact pins for the power lines, and you have to use both hands to tighten it down into the test head.
