RCA Connectors i.e Phono Plugs

[Edward R Cole]

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.

There used to be (and there may still be) in the Cinch line, locking
Jones connectors with steel tabs on each side with released when you
squeezed them.
