ABSTRACT:
A device is described for welding the ends of electrical conductors, especially strand ends, by means of ultrasonics which comprises a sonotrode, provided with a plurality of different projections, and an anvil, associated with the sonotrode, which anvil is provided with a plurality of different or like recesses which, together with the sonotrode projections, constitute compaction spaces for the strand ends. The anvil is disposed with its longitudinal axis coaxially with the longitudinal axis of the sonotrode, and the cross-sections of the compaction spaces can be simultaneously varied by rotation of the anvil relative to the sonotrode about the common longitudinal axis, so that a plurality of strand ends can be simultaneously welded by only one anvil. Several alternatives for the rotational drive of the anvil are also described.
