I was just wondering what the word "threaded" refers to in the context
of a Threaded Neill-Concelman (TNC) connector. I know threaded wires
contain thin metallic threads for flexibility, but I don't think this
is what threaded in TNC is talking about.
Thank you.
You are thinking of stranded wire, not threaded wire. A stranded wire
is made of several strands of small wire, twisted together.
The coupling ring of a TNC connector is threaded, like screws and nuts
are threaded. A closely related connector is the BNC - Bayonet
Neill-Concelman - the coupling ring on a BNC locks with a 1/4 turn,
where a TNC will take several turns to lock securely.
The UHF or PL-259 connector used for radio antennas, and the "F"
connector used for cable TV in North America also have threaded
coupling rings.
