RCA Connectors i.e Phono Plugs

They’re not long gone, nowadays they call them Cinch connectors. Not only Hams use them but most AVR and Stereo manufacturers. Take a look at a High End HI-FI or AVR rear side.

Those of us who have been around for a long time know what a *real*
Cinch connector looks like, and those "RCA" connectors do not.

Re: RCA Connectors i.e Phono Plugs

Cinch connectors like RCA plugs??? Not even similar.

By the way, all those plugs and connectors out there are lacking one
hugely great asset: An RC plug can be tightened if it becomes loose -
just a little squeeze is all it takes. And, I would sure rather have
several RCA jacks than a DIN plug to deal with when soldering!!!

Right -- a Cinch connector is VERY different. It has a square,
rectangular, or round body with blade-like contacts on the male and
receptacles on the female.

In reply to this post by Bob DeHaney

Hmmm ... not quite true. Well, actually not even close. For those who
did not experience the middle of the 20th century and in the interest of
historical accuracy:

Cinch-Jones connectors were popular back then because they came in a
variety of conductor numbers and were easy to assemble and solder, being
big enough [in contrast to the abomination known as DIN connectors which
came along later]. C-J connectors are square or rectangular, the "pins"
are blade-like [see current day automobile fuses] with a self-wiping
action on insertion, and they had a clamp device on the cable side that
would grip the cable outer sheath. They had the disadvantage that they
could be pulled apart fairly easily. I'm sure they're still around, I
just haven't seen one in a few years.

The RCA "Phono" connector accommodates two conductors, one of which is a
chassis connection [or should be, see k9yc.com/groundingandbonding.pdf]
I believe they appeared on the scene at the beginning of the "High
Fidelity Component Era" about the time 45 and 33 1/3 RPM records
appeared and were used for the audio paths between the various
components of a hi-fi system. They are small, round, and you can
increase the tightness of the shield connection by squeezing it
slightly. My K3 has one on the back which supplies power to the P3.
Nearly every TV sold at RC Willey, Best Buy, Frye's, Walmart, and Costco
has a set of them for video and audio connection. I like most folks
have a dozen or so of the cables that come with those TV's out in the
garage that are excess to our needs.

Those are now known as “Jones” connectors. No idea why the change, but they are becoming very hard to get with demand dropping.
Easy for us to work with, but they take up a lot of rear-panel space on equipment.

"Those are now known as “Jones” connectors. No idea why the change, but they are becoming very hard to get with demand dropping."

Still in production and available in a variety of configurations from multiple distributors at quite reasonable prices.

Browse for "Cinch Jones".

Re: RCA Connectors i.e Phono Plugs

I just built a Nanokeyer last night, and the connections for keyer and PTT
are both RCA jacks. However, in the documentation, they are referred to as
"cinch connectors". When cataloging the parts prior to building, I had to
look in the construction pictures to verify what kind of connector was a
"cinch" connector. I was rather surprised to see that RCA connectors have a
different name now, but RCA hasn't been a thing for a long time now so I
guess it was inevitable, seeing as it is listed as having gone defunct in
1986.

The curious can find a short two minute video of my Nanokeyer's first
testing here: https://youtu.be/_LLVS_Pk8zE
The RCA jacks, referred to as "cinch connectors" in the documentation, are
along the leading edge of the device, on the right side. Technically,
though, that's the back edge. It's just in the foreground because the cable
on my Bencher is short.

Cinch Jones Connectors

Yes. That's always been their correct name. Because of their relatively
large footprint as compared to modern connectors, they are used
primarily on legacy equipment. I have several '70s and '80s vintage
"brick" amps for 2M and 440 MHz that use them.

Re: RCA Connectors i.e Phono Plugs

In reply to this post by Gwen Patton

The Nanokeyer is the creation of Oscar, DJ0MY. It's possible that the
RCA Phono connector is called a "Cinch" connector in EU or DL, but in
the US [and I believe Canada], it is quite distinct from the
"Cinch-Jones" connectors, which I find are still available from the
several sources I checked.

I like them because I can get my arthritic hands around them and in the
days when a soldering iron was not a "weapon of mass destruction" in my
hands they were so easy to solder wires to.--

I'm an old ham (60+ years as a ham):

Originally called RCA and Phono connectors (I still refer to them as
that). Back of my K3 has a couple.

My brand-new, cutting edge, made-for-ham radio, super, A/D convertor*
has four of them to take two IQ baseband inputs from two SDR's to
convert to digital via USB2 port on a computer.

Its replacing my old M-Audio Delta44 soundcard (which had four
1/4-inch mono phone plug inputs).

I bought four 3.5mm mini-phone plug to RCA/Phono male connector audio
cables (6-foot) from Amazon to accommodate connecting the A/D to my
two LP-Pan's which are connected to main and sub-Rx IF's of my K3.

From Wikipedia:

"An *RCA connector*, sometimes called a *phono connector* or (in other
languages) *Cinch connector*, is a type of electrical connector commonly
used to carry audio and video signals."

https://en.wikipedia.org/wiki/RCA_connector

It was news to me that an RCA phono connector is also known as a "Cinch
connector". I think you're right that it must be a name used in Europe.

Re: RCA Connectors i.e Phono Plugs

Never were in UK to my knowledge, we always called them phono plugs and
sockets.

Jones connectors were always the black cased multi pin connectors with
rectangular blades, usually some at right angles to others. Think FT101
power connector.

I think Cinch was a manufacturer of Jones connectors at one time. Cinch
belongs to Belfuse now I think and they still make a lot of military
grade connectors, not Jones connectors though I suspect.

Here's an interesting history of the Jones connector found in a mail
back in 2012 on the Gearslutz web board.
https://www.gearslutz.com/board/geekslutz-forum/673980-cinch-jones-connector-whats-deal.html

Martin, HS0ZED

Hi. I'm not sure how i found this web site, but let me try to answer the
question.

My grandfather invented the first Jones Plug . I believe it was in the
early 1930's. His name was Howard Bevan Jones. He also manufactured lots
of different kinds of Jones plugs, with a company based in Chicago that
bears his name. At the height of the company's existence, it had about
200 <https://www.gearslutz.com/board/gear.php?id=48746> employees. the
early catalogs have LOTS of Jones Plugs.

At some point, Howard B. Jones and Co. was bought by Cinch
Manufacturing. For a number of years, the plugs were still called Jones
Plugs, but later on they were sold as Cinch Jones Plugs.

I , and others in my family, have old catalogs, photos of the whole
group of company employees, and lots of other memorabilia. My uncle,
Howard's son-in-law, tells tales of driving all over the Midwest to sell
them. Very entertaining. this uncle died at age 100 a few years ago.

I have tried in vain to find out a lot more. Cinch Mfg. was no help.
Even the family was quiet about what actually transpired in the early
days. Family lore has it that Howard also invented, and his company
manufactured, a device in slot machines that allowed the owners of the
machines ( casino owners, presumably) to adjust the odds of winning. You
can extrapolate whatever conclusions you find interesting from this
information.

Howard also invented the child's toy called the Hootnanny. It was widely
used, and is available from time to time on eBay
<https://www.gearslutz.com/board/gear.php?t=eBay>.

I could go on further, but perhaps this answers your question. I will be
interested if any other comments arise.

Re: Cinch Jones Connectors

If I remember rightly (and it's been a LONG time) there was an outer
shell pair made for at least some sizes which locked together external
to the shell. Even without the lock, the multi-pin models (especially
in the larger sizes) took some umph to get them apart.

In reply to this post by k6dgw

There is an easy locking device that can be added to any Cinch-Jones
connector.
The ones used on the older Yaesu radios had this device included.
You would have to practically destroy the chassis to get them apart if you
didn't squeeze it properly to dis-engage the lock.

Much tighter and higher current rating than those Anderson power poles
everyone seems to have fallen for.

You remember correctly. And they can require a tussle to separate on the bigger
