METHOD FOR CONNECTING STRANDED WIRES IN AN ELECTRICALLY CONDUCTING MANNER AND ULTRASOUND WELDING DEVICE

摘要

the present invention is an ultrasonic device 10, and an aluminum individual wires (32, 34) along the line (30) including a a method for connecting conductive by ultrasonic welding and the U-shaped carrier 40 made of a metal. Welding surface 80 a bottom surface 86 of the short open load has a trapezoidal shape with a small notebook base leg (78) is used. Bottom for the welding is inserted starting from the bottom surface and the side surfaces forming an obtuse angle relative to the bottom surface (88, 90) directly in contact with the stranded wire 30 to and from the welding condition into the U-shaped carrier 40 The total cross section of the stranded wire (F _L ) in relation to the space surrounded by the bottom surface and the side of the welding plane of the cross-section (F _S ) is F _S & F _L & 2F _{a S}
