Found in an old Soviet textbook ways to connect wires
Do you know what was good about the Soviet Union? Due to the fact that the state was surrounded by external (and sometimes internal) enemies, its population was prepared for everything: the country provided itself with everything necessary, and any work was honored.
So there were more useful books: encyclopedias, reference books and books from the series were printed in millions of copies #do it yourself. So I recently came across a book on self-repair of household electrical appliances.
From it I learned two useful and most importantly VISUAL ways of twisting wires: single-core and multi-core. It will come in handy if you do not have modern terminal blocks or a soldering iron with solder and rosin at hand.
Method one.
We strip off 3 cm wires on each side, and forward
Note:
twist the two sides of the twist alternately and as tightly as possible - with the most dense rings.
Method two.
For stranded wires.
And here it is important to finally squeeze the veins with pliers.
