It looks to me like a punch card exactly fits in there and the contacts
are what read the holes in the card. If a contact is made there is a
hole. If not the spot is unpunched. Hard to imagine that as a cable
connector. I don't actually know though.

The massive steel fixture locked the socket and plug together. The
cables I remember were about 1.5" in diameter and fabric covered.
