Method of making a passage or end node, and passage or end nodes

摘要

The invention relates to a method for producing a cross-section a rectangular geometry having passage or end node of electrical conductors by compacting and then welding the conductor by means of ultrasound in a height and / or width adjustable and rectangular in cross-section compression space of an ultrasonic welding machine, wherein opposite Limiting surfaces of the compression space sections of a sonotrode or one of these opposite counter electrode are. In order to connect difficult or in the prior art basically non-weldable electrical conductors to an end or transit node, which has a rectangular geometry in section, it is proposed that the conductor is inserted into a sleeve and then the sleeve with the conductors in the Compaction space are welded to the end or transit node rectangular cross-section.
