I'm looking for some in-line connectors suitable for carrying power (a few amps at perhaps a few dozen volts). Indoor use.
But, I want them to be idiot proof and easily mated/separated. WITHOUT having to be "focused" on that operation (e.g., you can mate a pair of headphones without even looking at what you are doing; the same is not true of a USB connector, D-shell connector, etc.)
E.g., barrel connectors, phone/phono plugs, etc. are ideal from this standpoint -- but not sure they are hardy enough for the long haul.
I've seen some automotive connectors that might work but they tend to be much harder (force) to mate and much more reluctant to separate!
I've currently relaxed my size constraints (smaller is better) in the hope of finding something that looks/feels good... with an eye towards identifying WHY that might look/feel good so I could search for a connector of similar qualities.
Cost is currently a low priority (< $10/mated pair?)
