BNC socket fatigue

<< < (6/6)

Hello, could anyone say to me why the connector manufactuers don't use nickel silver alloys for these kind of connector ?

 I took a closer look with some magnification and it seems the Jaycar line socket dielectric is too large in diameter (it mates ok with a Jaycar BNC plug).

Maybe your Jaycar connectors are 75 ohm BNC (that is, the ones for video), rather than the 50 ohm BNC used for test gear?

Edit: nah, I just double checked and 75 ohm BNC has an absence of dielectric, so that can’t be the issue.

Probably because BNC, like most of the common RF connectors, were designed by or for the US military, and standardized in DOD military specs. So their canonical specifications are in inches.
