1. The direct connection of multiple strand copper wire is shown in the figure below. Firstly, straighten the multiple strand core wire stripped of the insulation layer, twist and tighten about 1/3 core wire close to the insulation layer, and scatter the remaining 2/3 core wire in umbrella shape, and do the same for the other core wire that needs to be connected. Then insert the two umbrella shaped core wires opposite each other and pinch the core wires, and then divide the core wire ends on each side into three groups. First, twist the first set of wire on one side and wrap it tightly around the core wire, then twist the second set of wire and wrap it tightly around the core wire, and finally twist the third set of wire and wrap it tightly around the core wire. Wrap the other end of the thread in the same way.
2.The connection between single strand copper wire and multiple strand copper wire is shown in the figure below. Firstly, twist and tighten the core wire of multiple strand copper wire into a single strand, and then wind it tightly on the core wire of single strand copper conductor for 5-8 turns. Finally, refold and press the end of single strand core wire on the winding position.
