A method for production of a welded connection between at least one first electrical conductor and at least one second electrical conductor, in which the conductors are brought into a compression chamber enclosed by delimitation elements and welded therein by an ultrasound welding device, one of the delimitation elements forming a sonotrode which may be subjected to ultrasound vibration. According to the invention, in order to connect a first conductor in the desired circumference with second conductors, where the total cross-section of the second conductors for connection to the first conductor can optionally be greater than the usual cross-section with the ultrasound device used, the first conductor is welded sequentially with two or more second conductors in the compression chamber.

The invention claimed is: 1. A method for producing at least one welded joint between only one first electrical conductor which is a terminal comprising a rigid flat support portion attached to a connecting portion, and a plurality of second electrical conductors, each of said second electrical conductors being a single wire, comprising the steps of:inserting only one said first conductor and at least one initial second conductor into a compression space surrounded by limiting elements which are displaceable relative to each another, one of said limiting elements being a sonotrode of an ultrasonic welding device,closing the compression space by displacing the limiting elements to compress the only one first conductor and the at least one initial second conductor,welding the only one first conductor and the at least one initial second conductor by exciting the sonotrode to produce ultrasonic vibrations,opening the compression space with the welded first conductor and initial second conductor therein, and placing at least one additional second conductor in the compression space,closing the compression space to compress the at least one additional second conductor, andwelding the at least one additional second conductor to the first conductor or to the welded initial second conductor by exciting the sonotrode to produce ultrasonic vibrations, in a successive welding process.
