Hi, my project box is a large tin cookie box. I need to bring in +15V,-15V, and GND lines from my external bipolar power supply. (I wasthinking I would have a separate bolt for the chassis ground, whichwould go off to a big ground bus bar near my workbench.) For the threelines from the power supply, I am wondering what would be the best (buteconomical) choice for a power connector to mount into the side of theproject box. Something that sounded appealing was the spring speakerterminal clips I see on Amazon, but the downside there is they only comein pairs of two or four, rather than three, and they are color codedred/black which does not quite make sense here. I am inclined to leavethe wires on the power supply itself bare on the end, rather thanattaching some specialty connector to those.-- Christopher Howard

 If its rather low current,   coaxial power plug and Jack, or even
  a 1/4" stereo Jack. I prefer the binding posts.

They are not round, but Anderson Powerpole connectors can be
very useful.  The ground connector mates before the other ones
and they can be built up into various multi-contact combinations.
The current rating may be overkill for many projects, but they
are versatile and reliable.
