I have an existing LED light curtain but I would like to redo it in more robust way. It has a main cable with 6 branches hanging down like this:

Battery&DC-DC___________________
                |  |  |  |  |  |
                o  o  o  o  o  o
                o  o  o  o  o  o
                o  o  o  o  o  o
                o  o  o  o  o  o

At the moment the T-branches are just twisted and soldered around the main but soldering tends to break because branches are flexing a lot.

Are there some recommended T-connectors available? It can be permanent or detachable.

Edit: The wire gauge is not fixed, I think at the moment it uses 0.75 mm²

Something like a 3M Scotchlok T-Tap connector might be what you want.

Be sure to use stranded wire if your application requires flex, it will impart less stress to connections (soldered or not).
