Abstract
The invention relates to method for producing a connecting passage node or end node which has a rectangular shape in cross section and consists of electrical conductors. The nodes are produced by compacting and subsequent welding of the conductors by means of ultrasound in a compression chamber of the ultrasound welding machine of which the height and width can be adjusted and which has a rectangular shape in cross section, wherein opposite delimitation surfaces of the compression chamber form sections of a sonotrode and an opposite counter electrode, respectively. To connect electrical conductors which are difficult to weld to an end node and/or connecting passage node, the conductors (50, 52, 54) are brought into a sleeve and, subsequently, the sleeve (62, 65) is welded with the conductors in the compression chamber to form the end node and/or connecting passage node (49) having a rectangular cross section.
