Method and apparatus for connecting winding materials to terminal elements

A device for connecting winding materials to terminal elements, the winding material being wound around a terminal element and connected mechanically and electrically to the terminal element at at least one connection point by the application of energy, the winding material having an electrically insulating cover, comprising:

• a winding device having a wire-feed device for supplying the winding material and having a winding nozzle for dispensing the winding material onto the terminal element;
• and
• an ultrasonic horn mechanically connected to the winding nozzle for transmitting ultrasonic vibrations to the winding material, the ultrasonic horn and the winding nozzle forming a guide for the winding material;
• wherein the ultrasonic vibrations in an ultrasonic range are coupled into the winding material via the winding nozzle, thereby removing the insulating cover of the winding material in a region of the connection point and thereby effecting an electrical connection between the winding material without the insulating covering and the terminal element, and wherein the winding nozzle performs predetermined path movements and wraps the winding material end around the terminal element to connect the winding material to the terminal element.

• an ultrasonic horn coupled to the winding nozzle for transmitting ultrasonic vibrations to the winding material, the ultrasonic horn being rigidly located between the winding nozzle and the terminal element;
• wherein the ultrasonic vibrations in an ultrasonic range are coupled into the winding material via the winding nozzle, thereby removing the insulating cover of the winding material in a region of the connection point and thereby effecting an electrical connection between the winding material without the insulating covering and the terminal element and wherein the winding material moves contiguously past the ultrasonic horn for the application of the vibrations.
