...I remembered the MagSafe connectors for Apple laptops but I couldn't
find anything off the shelf that was: 1) orderable, 2) had enough pins,
and 3) was easy to integrate into the skin of a rocket. It doesn't look
too complicated so I decided to try making a custom version. I found
these Mill-Max spring loaded pins...
There are off-the-shelf "negative insertion force" connectors, from
connector suppliers like Positronic Industries -- many-pin connectors
which have to be held mated by external forces, and will spring apart if
the external force is removed. (They're used in spacecraft-to-launcher
umbilicals, for example.) Haven't looked lately at availability and cost,
though.
Here are some photos of a prototype I made yesterday.
Cool!
