[Elecraft] RCA Connectors i.e Phono Plugs

[Martin Sole]

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.

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.
