One of my pet peeves is "jack plug". In the UK it seems to refer to the 1/4 inch (retro-defied as 6.5mm) connector with either two circuits (TS = Tip, Sleeve) or three (TRS = Tip, Ring, Sleeve)
I grew up understanding that "plug" refers to the male gender, while "jack" refers to the female of the species. Perhaps "jack plug" is some newfangled politically-correct term here in the era of LGBTQQI (probably more variations that I can't remember?)
So I never know whether "jack plug" refers to a cord-end male connector, or a panel-mount female connector? One needs the context to be sure.
Furthermore, the elegant and rugged Switchcraft 297 that I grew up with as a child now costs $4-5!
And Switchcraft is selling cheap Chinese designs with goofy spiral spring "strain relief".
