Why rotary-tip on 4mm banana plugs?
(1/8) > >>
MrCAL:
What's the advantage of the rotary-tip on some banana plugs?
One might argue it just add one more "problematic" connection-point?


Original Fluke prope from model 177. Can actually be unscrewed, which add yet another additional connection-point.





I did notice that when you insert the plug with a rotary-tip it does clamps/tightens to it's "body" and make good connection, but still an additional connection compared to the "standard" 4mm banana plug (picture 4)

Cheap to manufacture from stamped sheet.

The last picture are better (IMHO), they provide a reliable connection every time.

I have had too manu bad connections from the springy spinny ones (admittedly cheap ones), I even soldered a batch of them once to stop them spinning because they were so bad.
Jeroen3:
The stamped metal sheet needs to elongate when inserted. There are some audiofoolery variants around where the flex mechanism is more fixed, but I suspect their mating cycles are a lot less.

Being a loose sleeve also makes it much easier to rotate when inserted compared to, for example, the one made from spring pins. (your last picture)

The kind in the last picture are only good if it’s good quality product — I have encountered cheap versions of those where the bundle of wires has no springiness and just stays compressed after a few insertions.  :palm:

In a nutshell: any style is fine if it’s high quality, and any style can suck if it’s low quality.
