I don't think an RCA qualifies - it's a co-axial connector. A jack is
a single prong device with the various contacts in line.


My 1912 edition of "The Practical Telephone Handbook" (where would I be
without it?) refers to "plugs" and "spring-jacks". The plugs are just
the same as the sort you refer to above, being 1/4" dia and coming in
two and three pole versions, plus the special 3-pole type for CB
switchboards (now known as "B-gauge"). These plugs then plug into the
"spring-jacks" which again come in a variety of flavours: 2 and 3 pole,
break jacks and branching jacks etc., but all conforming to the same
general form. Of course in those days phono connectors, XLRs etc. etc.
didn't exist so the opportunity for confusion was limited.

ISTR 'Jack' is another name for male, ie jackrabbit, and refers to the
penis. ;-)
