How can a wire be connected to several contacts?

Question

Electronics

I need to connect the wire shown in the picture to the legs of 4 LEDs. I know for sure that these are not short jumpers from the legs to the common wire. But I know that heat shrink should definitely be put on the contacts.
I need to describe the installation of this node. There is no developer. Nothing is written on the assembly. I know that the tube should be put on legs, and one wire should power 4 legs of 4 LEDs.

Answer 1

1) Twist the four legs together with the wire, solder and put on heat shrink.
2) Bend the wire opposite the diode, clean the fold, put on heat shrink, solder to the leg, stretch and heat the heat shrink ... repeat 3 more times.
...
And more M-2 ways, depending on specific conditions.

Answer 2

The meaning of the question is not entirely clear. Are you modifying a finished device, or what are you even trying to do?
If you were to breed a printed circuit board, then such questions would not arise. If you did everything "in the air" - too.
Hint: LEDs fit perfectly into dupont connectors or breadboard.

Answer 3

Firstly, this topic is a duplicate , and duplicates on this resource are prohibited by the rules.
Next, they already wrote to you there, so I will repeat - you show the circuit diagram and ask to describe the installation to you. It's impossible to do this - we don't know (well, if you dig your comments, it turns out you can dig out what kind of LED you have there).
To describe the installation, you need an assembly drawing or a wiring diagram, or at least a photo of a similar device, and not that's all.
