I have a 750m 0.75mm² wire on a spool that needs a quick disconnect connector of some sort on it so it can take it off in 250m lengths. But it has to handle the tension of being spooled up. Any ideas?
In an ideal world it would be a male and female banana plug thing, but that wouldn’t hold under tension. So I’m hoping you folks have ideas.
Have you seen these knife connectors used in aviation? They are genderless and lock together. Of course your crimp better be solid - meaning proper connector for the wire size and proper crimping tool die.
No never seen them. Will investigate. I wish the pictures made it more clear what the actual mechanism is. Maybe I need to handle one in person to understand.
They are kind of like two hands making a handshake - they just twist/slide into each other and each is then looped around the back of the other. Very simple and effective
Depending on how frequently it needs to be connected and how much tension it needs to hold, it might be worth taking a look at some Wago connectors, as i’ve generally been impressed by how well they hold. Not really an option if the connection needs to be regularly connected and disconnected, but if it’s just occasional it could be an option.
Outside of that I would second Aubeynarf’s suggestion, but don’t have much personal experience with them.
You could try a bullet connector. They take quite a bit of force to disconnect.
This seems like a decent suggestion. Also, inexpensive and field repairable.
