I vaguely recall reading about a "magnetically-coupled" plug than used strong magnets to "hold" the contacts together.

The "powered" end had a trio of concave-looking circular "sockets" that were held against/in-contact-with by the magnets to the "un-powered" trio of convex-looing circular "plugs."

A lot of force was needed to "directly" pull the two apart, but they could be easily "tipped" apart.
