Abstract: A connection (V) of an electrical aluminum cable (1) with a connection piece (4) of another metal, especially of copper or a copper alloy, is brought about by crimping the wires (2) forming the aluminum cable (1) together in an end region and by welding to the connection piece (4), especially by a friction welding process. Moreover, the frictional heat between the materials is used to melt the two materials and to join them with each other without additional welding material. The aluminum cable (1) is provided for this purpose with a support sleeve (13) crimped upon it, which practically forms the individual wires (2) at the connection point into a solid surface, which is itself welded to the connection piece (4). Consequently, connection pieces of copper can be connected tightly and with good electrical conductance, without the danger of corrosion existing in the area of the connection due to various electropositive and electronegative metals.

Abstract: A cord (3) which consists of a plurality or a bundle of individual filaments (2), especially individual wires, can be inserted into an opening (4) with a stripped or bare end (1), even if the filaments (2) are spread out at this end (1). The cord is grasped near the free end (14) of the bare filaments (2), and the filaments (2) are pressed together over the total circumference of the cord. The free end of the cord is provided with a contour which corresponds to the receiving opening (4). The compacting occurs for this purpose in such a manner that opposite the pressure position a projection at the free end (14) still remains, which now in this contoured shape fits and is inserted into the opening (4). Thereafter, the bundle of filaments (2) is then pressed together again at a slight distance from the opening (4), and by this aforementioned distance is inserted into the opening (4) or the sheath (5).
