Method for manufacturing an effective electric contact point at the end of an electrical line

Method for manufacturing an electrically effective point of contact on an end of an electrical conductor, the electrical conductor having a plurality of stranded wires composed of aluminum or an aluminum alloy with exposed ends, with an end of the electrical conductor being arranged vertically along its axial direction with said exposed end of said stranded wires facing upwards, said method comprising:

• initially a holder is placed surrounding the end of said vertically arranged conductor so that the front side of the conductor is exposed and accessible from the top,
• by which after the point of the electrical conductor is heated by a heat source to a temperature of at least 2000° C. such that surrounding oxide layers which surround the individual stranded wires are melted away or vaporized until all the exposed ends of the stranded wires of the electrical conductor, including the same surrounding oxide layers, form a one-piece fused contact part;
• and
• cooling the fused contact part together with the end of the electrical conductor.
