So is it missing an insulator or is it supposed to not have one?

That's why all my receptacles are GFCI.
It could easily prevent a mishap like this. When I first started using them, I bumped a chassis with a grounded cable TV coax and it tripped instantly, no damage to the set. It happened a few times.
Also, none of my test equipment is grounded. I use those 3 to 2 prong adaptors on the equipment that has grounding plugs.
AC/DC sets, an isolation transformer.
