| 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. |

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) |
