Embodiment Construction

[0036] In order to connect electrical conductors of different materials or material properties, in particular cores made of fine or very fine wires, intact by means of ultrasonic welding to form transition nodes or end nodes, wherein at the same time high mechanical and dynamic load-bearing properties as well as good electrical connection and can achieve the final shape of the square, according to the proposal of the present invention, the wire is first loaded into the sleeve, then this sleeve is loaded into the compaction chamber of the ultrasonic welding device together with the wire, and in this compaction Compacted and welded in a solid cavity.

[0037] exist figure 1 The principle structure of the corresponding ultrasonic welding device is shown in . The ultrasonic welding device or ultrasonic welding machine 110 generally includes a transducer 112 , if applicable a horn 114 , and an ultrasonic horn 116 . Attached to the sonotrode 116 or its surface is a multi-part coun...

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.

Description

technical field [0001] The present invention relates to a method of compacting and then welding a wire in a compacting chamber of a welding machine, such as an ultrasonic welding machine, which is adjustable in height and / or width and is polygonal in cross section, such as a rectangle, to process a Method of making electrical conductors such as wire cores with a polygonal, eg rectangular, geometry in cross-section for transition nodes or terminal nodes, wherein the opposite boundary surfaces of the compaction chamber are sections of electrodes such as ultrasonic horns or with The segment corresponding to the corresponding electrode of the ultrasonic welding head. The invention also relates to a transition node or end node consisting of mutually compressed and welded electrical conductors, wherein the transition node or end node has a polygonal, eg square, shape. Background technique [0002] A corresponding ultrasonic welding method is described in EP-B-0 723 713. The esta...
