Cinch-Jones always referred to square black connectors with large "blade" pins.
They were used a lot with early ham amplifiers and until recently in
Ham-series rotator controllers; now they come with 9-pin round
connectors populated with 8-pins which one crimps onto rotator wire
and inserts (like a Molex connector). One has to have special
removal tool to pull the pins. I recently bought a Ham-IV and T2X
rotator with those used at the rotator. Control box still uses
Cinch-Jones 8-pin. Older Ham rotators sold by Hygain (and CDE) had
simple screw strips.
I bought one of W6PQL 2m kilowatt amps and it came with a 12-pin
Cinch-Jones, which is great since the amp draws 40A at 50v thru the
pins. I paralleled two pins to be sure to handle current. Other
pins carry 12v for control board and several lines for remote
monitoring/control.
I can still find them in internet searches (usually Amazon companies).
Internet search shows pictures:

You will note some pictures show RCA-phono types with Cinch name.
Interesting history given in recent link.
Other "old" connectors used in ham radios were Octal Plugs (on many
Heathkits) and 4-pin mic connectors. These days one finds computer
type connectors in use.
